  • Focus: These mainstream and well-regarded documentaries will quickly put a critique of the US Food System on the table. Check movie availability. Take some notes on: 1. Facts that you are surprised by, think important, or are suspicious of.; 2. Questions raised by the movie; 3. Claims or thesis that the movie's documentary evidence seems to support. Note segments or narratives. Try to note some names.
  • Sonnenbergs, C 1, "What is the Microbiota and Why Should I Care?"
  • Recommended: View one of these gut movies:

Sonnenbergs, C 1, "What is the Microbiota and Why Should I Care?"

  • How the world looks to a microbiologist! "Without microbes humans wouldn't exist, but if we all disappeared, few of them would notice." 10
  • Introduction to the Tube and digestion
  • Microbiota Case against the Western Diet
  • Sets the history of human diet in context. Agriculture already a big change, but then industrial ag / industrial foods
  • Adaptability of M remarkable. Makes us omnivores.
  • Baseline M - cant' be health Western Diet eaters. studies of groups like Hadza -- far more diverse.
  • 19 - Evolved Symbiotic relationship between us and bacteria --
  • types of symbiotic relationship - parasitic, commensal (one party benefits, little or no effect on the other), mutualism.
  • The heart warming story of Tremblaya princeps and Moranella endobia. (21) -- why we should be happy mutualists. Delegation and division of labor might create resiliance.
  • 22-30 - Cultural History and History of Science on Bacteria -- or, how germs got such a bad name.
  • Pasteur -- germ theory of diseases.
  • The Great Stink 1858 London, Miasma theory disproved, Cholera bacterium, not isolated until near end of century. Dr. Robert Koch.

  • Contemporary research: gnotobiotic mice. early fecal transplant studies of [Dr. Jeffrey Gordon].

Food Inc & Fed Up

  • Food Inc Notes As we review the movie, take notes to answer the following questions: 1) What are the distinctive features of an industrial approach to food? 2) What is the relationship of "organic" to "industrial"?

Sonnenbergs, C 5, "Trillions of Mouths to Feed"

  • Microbiota extinction -- not just from change in foods, less fermented foods, more sterile food and sterile environments.
  • To improve gut diversity, eat ferments and fiber. whole grains and rice. pets, gardens...pets help with our microbiota. (Elsewhere, food provokes an immune response. That's a good thing.)
  • introduces acronym: MAC -- these are really complex carbs.
  • Microbiota mechanisms:
  • direct response to diet, "recyclers",
  • life is hard for our M germs: no oxygen down there and transit time is fast. So they make SCFAs that can metabolize in the blood stream where there is oxygen.
  • Why feed the gut? Isn't that just more calories? (116) - No. people with high scfa diets lose weight, decrease inflammation, Western diet diseases. Back to the connection between satiety and nutritional health. (N - S - P)
  • Sig. claim: 117: "Providing more..."
  • History of research -- field doctors: Thomas Cleave, 70s "The Saccharine Disease" "Bran Man"; Denis Burkitt studies comparing Western and Africans on fiber, stool quality, and health. Note on "transit time". Overconsumption of refined carbs. (S&S mention here that public health attention didn't stay on refined Carbs. fear of fat, elsewhere "lipidphobia" took more attention.)
  • Carb chemistry/metabolism basics -- 120: also in our nutrition textbook chapters. Note unique types of saccharides in particular foods: read 121 and 126; Oligosaccharides ferment in gut. insulin resistance. Big point here. At the level of MACs, plant chemical diversity is reflected in diversity of M. and it's products.
  • 122: glycemic index and glycemic load. show how to look up food values. note that glycemic index isn't really an issue with most whole fruits and vegetables.
  • Measuring MACs - the authors acronym for Macrobiotically Available Carbohydrates. - no standard measure of dietary fiber (note discrepancies from above.) 124. mention that undernurished gut bacteria can start eating the mucus lining of the gut. (This was also in a segment of one of the gut movies.). Feed them or they'll eat you!
  • RDAs: 29/38 grams. Actual 15 grams/day. 126: Notes that not all complex carbs are available to the M.
  • research discovering enzyme in nori, a seaweed based sushi wrapper: found in Japanese guts. Helps digest fish. Note: Terrior. Local adaptation of the M.
  • 128: Dutch research on rich and poor M. richness of M correlates with anti-inflammatory effects, thinness, low insulin resitane, metabolic potential for procarginogenic compounds.
  • Gordon's famous 2013 FMT mouse research: need M and M-supporting diet. Note caveat 129. Can't just benefit from the microbes alone. Fecal transplant with poor diet killed off beneficial bacteria.

Refining MACs out of the diet.

  • What's wrong with refined cereal seeds (130) (like Montgomery's account). Wheat bread vs. Wheat berries. The form of the food matters to the fiber count. Highly milled whole wheat flour will behave differently in your gut that rough milled.
  • What about the Inuit?
  • What about excess gas? Interesting consolations.
  • 135: Note their dietary advice. A high MAC, non-industrial omnivorous diet.

Sonnenbergs, C 7, "Eat Sh*t and Live" (Recommended)

  • This chapter is more focused on diseases that have been treatable with new knowledge about the M, and the limits of that research currently.
  • Gastroenteritis, infectious diarrhea, -- culprits like Giardia, Salmonella, and norovirus.
  • Immunological effects of the M: "colonization resistance" - mechanisms (165) - crowding out, bacteriocidal chemicals. Problematic nature of antibiotics in the M.
  • C. difficile (Cdiff) -- associated disease CDAD. 14,000 deaths in US a year. why antibiotics don't always help. spores.
  • 2013 Dutch FMT therapy for CDAD - 94% cure rate (note earlier researcher in 50s who tried this.)
  • Antibiotics -- Interesting that Americans not only eat the Western Diet, but take high levels of antibiotics. Effects of Cipro on M. -- decrease in volume (-10-100x) and diversity of bacteria (25-50% of species). Test subject had diverse responses. Some recovered M in several weeks. Some sustained damage. 2nd round of Cipro hurt everyone's M. Microbes in the gut can trigger immune responses and some even release anti-biotics directly at pathogens.
  • IBS and IBD - 177: Finding your personal "transit time".
  • Difficulties with FMT as a therapy: dangers in introducing new bacteria into someone's gut. Might be hard to remove. (Like issue of releasing GMOs in environment.)
  • Limited results from FMT in humans for obesity treatment. or inflammatory bowel disease.

Some implications of Microbiome research

  • The form of the food you eat partly determines the kinds of nutrition you can get from it.
  • Nutritional information about the food is incomplete for assessing potential nutrition from the food.
  • Which part of you eats the food affects what kind of nutrition (and other benefits) you receive from it.

Nestle, "Introduction: The Food Industry and 'Eat More,' from Food Politics"

Intro: "This book exposes the ways in which food companies use political, government and professional support for the sale of their products."
  • Note opening picture of food industry: overproduction, connection to publicly traded companies creates need to sell more.
  • On the other hand, this model worked well to meet nutritional deficits that continued well into the 20th century for many americans.
  • historic note: early 20th century still battled nutritional disease from inadequate calorie intake. Then shift to overconsumption.
  • her professional experience (3) with editing Surgeon General's report: no "eat less meat" - Government gave up producing the report in 2000. Authoritative advice would have required some "eat less" messaging. Could say "eat less sat. fat". (Note nutritionism.)
  • Side note: "New Dietary Guidelines Crack down on Sugar but red meat gets a pass," NPR Jan 7, 2016 [1]
  • her thesis: "that many of the nutritional problems of Americans—not least of them obesity—can be traced to the food industry's imperative to encourage people to eat more in order to generate sales and increase income in a highly competitive marketplace."
  • note her concise nutrition advice on p. 5ff. A bit old school and reductive.
  • 7ff: stats on diet and mortality, childhood obesity. Note that she does endorse "energy balance" as legitimate (more so than in Fed Up, but she would agree with their point)
  • 8ff: food production and consumption trends. more total daily calories (3200 in '70 to 3900 in the 90's), increased consumption of low fat foods, more restaurant food, where we are in relation to USDA advice. see p. 10. low variety of food in actual diets.
  • 10: Conclusion on sources of excess in American diets. Read.
  • 11: dimensions and trends in food industry and international - European diets are approximating US diet in calories from fat. "nutrition transition" idea that as cultures move from primary healthy diets to industrial diets they ironically seek more calories and want cheap calories. US less than 10% of income on food (see wiki links for more)
  • Some food economics: percent of food value from farming across food types p. 17. Advertising spending on industrial food, using philanthropy for branding, new food products (25)
  • Follow data: size of industry, timeline of tobacco company purchases of industry. Farm value vs. Marketing of industrial food. p. 18. Stop to consider explanations.
  • Why might it matter if farm value in food products is a declining proportion of food value in dollars?
  • Social trends: half of all meals consumed outside the home, 25% as fast food, female labor market participation, changes in perception of "cooking". Scratch cooking associated more with sub-cultures.
  • Q: Is there a basic conflict between good food policy and treating food as a product that free markets can optimize?

  • Gastropod episode, "The End of the Calorie"
  • Focus: The Gastropod episode will give you alot of information about the way the "calorie" came about as a unit of measurement and the complexity of measuring food energy.
  • Moss, Michael. Chapter 4, "Is it Cereal or Candy," Salt Sugar Fat. (pp. 68-93)

Gastrpod, "The End of the Calorie"

  • Antoine Lavasier — Guinea pig in coffee urn - we “burn” food chemically. Change in temperature of water the pig is in. 1st “calorimeter”. Axed in French Rev.
  • Later defined by a german scientists (Favre and Silbermann in 1852 or Mayer in 1848) as: Amount of heat energy to raise 1 gram of water by one degree centigrade from 14.5 to 15.5 at sea level.
  • We still use calorimeters......museum of calorimeters also (Penn State). Nestle recounts seeing example of a room calorimeter. Visit to contemporary calorimeter. USDA site in Maryland (see photo): Converted walk in cooler. Implication that the woman with the sewing machine “made a mess”? 8:50
  • Bomb calorimeter. You burn the food. Segment on how it works.
  • Wilbur Atwater. Atwater values. USDA scientist. “Father of nutrition science” (Nestle likes him.). 4,000 food values. Method...omg. Potental energy (bomb cal value) - excretion = value. 4 cal/gram of carb or protein. 9 calories per gram of fat. (7 alcohol).
  • Recent evidence about variability of calorie values — researchers repeating Atwater research, but using additional measures. David Baer and Bill Rumpler both work at the Food Components and Health Laboratory at the USDA-ARS headquarters, in Beltsville, Maryland. Check out Baer and his colleagues' papers on the difference between the calories on the label and those our bodies can extract for almonds and walnuts.b. “The food is free, but you have carry ...”. 5-6% off on tree nuts, 30% on almonds, 21% walnuts,
  • Richard Wrangham is the author of Catching Fire: How cooking made us human. Harvard medical anthropologist. —
  • First to show that cooking changes food to allow earlier digestion (small intestine) and greater calorie recovery. 30% for starch. Also cooked meat, peanuts. All research on mice (and pythons). Still hard to say what the variation will be for us. Maybe 20-50%, depending upon food.
  • What about heat extrusion, also called Food Extrusion? (Used in cereals.). Industrial food might raise calorie levels relative to atwater values. That's a good thing, right? Or is it? (Note that early digestion means less activity for large intestine.)
  • Digression on Food Extrusion (not in podcast):
  • [2]
  • So, if extrusion damages nutrition, what about pasta? Why doesn't it have a high glycemic index like breakfast cereals?
  • "In pasta products, gluten forms a viscoelastic network that surrounds the starch granules, which restricts swelling and leaching during boiling. Pasta extrusion is known to result in products where the starch is slowly digested and absorbed (59,60). Available data on spaghetti also suggest that this product group is a comparatively rich source of resistant starch (61). The slow-release features of starch in pasta probably relates to the continuous glutenous phase. This not only restricts swelling, but possibly also results in a more gradual release of the starch substrate for enzymatic digestion. Pasta is now generally acknowledged as a low glycemic index food suitable in the diabetic diet. However, it should be noted that canning of pasta importantly increases the enzymic availability of starch, and hence the glycemic response (62).[3]
  • Indivudal variation: age, gender, muscle mass.
  • Sarah Haley — scientist claiming counting calories didn’t work for weight reduction. After second child, big change in metabolism.
  • CALORIES AND THE GUT MICROBIOME - how does microbiome affect calorie processing.
  • Peter Turnbaugh's lab at the University of California, San Francisco, promises "better living through gut microbes." In our conversation with him, we discussed this study on the effects that transplanting gut microbes from lean and obese twins had on the weight of mice. Further examples of the impact of microbes on energy balance can be found in this paper on one woman's weight gain following a fecal transplant, and this paper on how risperidone is associated with altered gut microbiota and weight gain.
  • microbiota creates variation in calorie capture.
  • 36:45. Sarah Hailey comment.
  • CALORIE REPLACEMENTS?
  • Susan B. Roberts is the creator of the satiety-based "iDiet." She has also done extensive research into the accuracy of calorie counts on menu labels. David Ludwig's book, Always Hungry?, also proposes measuring foods based on their satiety score. Adam Drenowksi's Nutrient-Rich Food Index is explained here.
  • They acknowledge that we don’t have a better standard, but other methods might tell us more.
  • DAVID WISHART AND METABOLOMICSDavid Wishart's research group is based at the University of Alberta. You can check out the Human Metabolome Project Database online here. And the Israeli study on personalized nutrition based on individual glycemic responses is available online here.
  • WHY THE CALORIE IS BROKEN
  • We wrote a feature article for Mosaic, the online publication of the Wellcome Trust, to accompany this episode. You can read it online here.
  • THE CHEMICAL DEFINITION OF THE CALORIE
  • In the episode, we say that a calorie is the amount of heat energy needed to raise the temperature of one gram of water by one degree centigrade, from 14.5º to 15.5º, at one unit of atmospheric pressure. This is accurate, but it is misleading, because throughout the rest of the episode, we are discussing a different kind of calorie—the kilocalorie, which is the amount of heat energy needed to raise the temperature of one kilogram of water by one degree centigrade. The kilocalorie is the number we see on our food labels and recommended daily allowances, but no one other than chemists actually calls it the kilocalorie. Instead, it has been shortened to "calorie" on labels and in everyday usage. Throughout our episode, we follow common practice by calling a kilocalorie a calorie, but then we mistakenly gave the definition of a true calorie without noting the difference. We apologize for any confusion!
  • The University of Alberta's David Wishart offers us a glimpse of the future, in which truly personalized nutrition advice will evolve from the emerging science of how the chemicals in our bodies interact with all the different chemicals in the food we eat. And Susan Roberts, director of the energy metabolism laboratory at the Tufts USDA nutrition center, suggests an alternative unit as a replacement for the traditional calorie.

Moss, Ch. 4, "Is It Cereal or Candy?"


  • John Harvey Kellog vs. Will Kellog. Drama at Battle Creek Michigan.
  • note early ad claims by Post for Grape-Nuts and Postum -- shows something about food psychology and tendency to fad diets.
  • $660 million to $4.4 billion 1970 to mid 80s.
  • breakfast cereal growth coincided with increased labor participation by women. Easy meal to eliminate cooking for, especially with cheap milk.
  • Ira Shannon, Dental activist!, measures sugar content on breakfast cereals after Feds refuse. 74
  • Jean Mayer, Harvard nutritionist, big deal, early obesity research. title for chapter from an essay of his. urged moving cereals over 50% sugar to the candy aisle. Look at current and puzzling data for frosted flakes [4].
  • note nomenclature issue in the public policy discussion: breakfast cereals v. breakfast foods. who cares?
  • 76: Key theoretical claim: The breakfast cereal industry responded to concern over sugar in part by developing market campaign to children and by putting marketing in charge of product development (85)
  • 76ff: political story of sugar in 1977 -- FTC over responds to concern about marketing of cereals to kids by banning all advertising to kids. battle between advertising lobby and FTC. advertising ban failed. Washington Post labels it "the National Nanny". role of gov't issue. "social engineering". still, FTC report was credible and damning on the topic of advertising sugar to kids. note the industry documents showing the industry's effort to "engineer" their consumer.
  • 2/3 price of the cereal is in the advertising (!).
  • 1990's competition from store brands -- 82ff: note value of minute market share movements. "product news" - continual change in marketing. Kellog is losing out at one point, Moss finishes chapter with their strategic response: concept of "permission" (when a taste is close enough for the consumer to say that had an experience of a real thing through the taste, example: the taste of rice crispy treats in a cereal. "We didn't have to be literal. We just had to have the flavor spot on." (87)
  • Key theme from Kellog's market share loss: This is a real crisis for a food company. 87ff. CinnaMon/Bad appple campaign
  • odd twist - the "Cinnamon" and "bad apple" commercials. [[5]]
  • Frosted Mini-Wheats became "brain food". fraudulent research. 91-92 Commercial in this NPR story Also, check out these oldies. [6]
  • Kellogg even tried comparing kids who ate Mini-Wheats to kids who skipped breakfast!
  • Interesting. Possible thesis: We entered a "post truth" era in the food industry before politics.
  • The Kellogg story reinforces the idea that food may be a difficult business to subject to the demands of publicly traded corporations. (Note: Doesn't mean food can't benefit from other market realizations.)

  • Complete Carbohydrates worksheet (10 Q&W points)
  • From the main wiki page, follow the link to the carbohydrates worksheet (https://wiki.gonzaga.edu/alfino/index.php/Carbohydrates). Copy and paste the worksheet into a word document, fill it out, and print it. You can make additional notes or edits in class, but I will collect these in class for credit.


Nix, Chapter 2, "Carbohydrates"

  • Nature of
  • Carbs are a source of short term energy. All Carbs break down into sugars during metabolism.
  • Scale of simple to complex. Simple sugars (monosacharides) don't even require digestion. Starchs are complex and "slow burning".
  • Limits to the "energy" metaphor:
  • carb levels and types help regulate other processes like insulin response,
  • fiber helps with useful bacteria production, appears to reduce colon cancer, helps with bowel function and avoidance of diverticulosis.
  • carb types and level signal body to break down protein for energy or not.
  • soluble fiber binds bile acids, lowering cholesterol
  • per capita HFCS (high fructose corn syrup) up from .12 tsp daily in 1970 to 11.18 tsp in 2008.
Note warning on high fiber low iron-rich diet. Phytic acid in this diet can cause iron deficiency. You can get too much fiber, but most Americans don't.
  • Functions of
  • reserve fuel supply is stored as glycogen in muscles [[7]] and blood sugar. Roughly 1-2 hours of aerobic exercise. glycogen also stored in the liver to regulate blood sugar.
  • carbs keep us from going into ketosis, but as we've noted, you can have a diet based on having your body in a state of ketosis.
  • Digestion
  • primarily in small intestine, through enzymes such as amalyse from the pancreas, and from the "microvilli" of the intestine which contain specific disaccaridases: sucrase, lactase, and maltase. (digression from p. 26 text box on dairying as textbook case of gene-culture co-evolution.)
  • As we learned earlier in the term, you can think of carbs as feeding both you and them. Neither fat nor protein get into the large intestine in significant amounts. We feed our gut bacteria with carbs.
  • Recommendations
  • decrease added sugar to less than 10% of calorie intake. Current ly 28 teaspoons of added sugar a day.)
  • increase proportion of complex carbs.
  • Two practical take aways:
  • Calculating Carb amounts for your diet and noticing carb types and values in your diet. Think about your "carb profile". Is it tilted toward a high glycemic diet?
  • Understanding carb related advertising and health claims. How and why does industrial food tend toward refined carbs?

Moss, Ch. 8, "Liquid Gold"

  • Wallace and Grommet on cheese: [8]
  • Stories told in this chapter: Dean Southworth and Cheese Whiz; James Lewis Kraft, cheese entrepreneur!; story of cheese in the US food economy; Kraft marketing of Philadelphia cream cheese and Paula Dean story; closing research on visible/invisible fats. There is no upper bliss point for fat!
  • Cheez Whiz; altered from original, but never a gourmet experience. Pretty much no cheese in it.
  • Am cheese consumption: 33pounds/year; 50 gallons of soda
  • traditional consumption of cheese (mention Cesare & Ornella)
  • Kraft orgins story: invented canned cheese. used in field rations. 1928: Velveeta, high sodium as by product of industrial process.
  • point is that industrial cheese can be made in a few days. fresh cheeses are quick, but real solid cheese can take 18 months or more to mature. (Is that a real value or just an old way of doing something?). note 167.
  • Cheese in US food economy
  • anti-fat campaign of 80s led to overproduction of milkfat ("Cows can't make skim milk" - maybe a clue that something's backwards), gov't subsidized milk and cheese; huge warehouses of cheese (1.9 billion pounds at a cost to taxpayers of 44billion a year) ; Reagan admin stopped this, but also raised funds from the industry for new marketing efforts to promote milk consumption.

  • 2008 Dutch research
  • visible / invisible fats and satiety, perception of fat. results: everyone underestimated fat content, visible fat group full faster, about 10% more.
  • Personal advice: buy whole fats and eat them sparingly and mindfully. Compare satiety with Costco sized skim-fat products.
  • Puzzle: many cultures eat much more cheese than Americans. French 53, Italy 44, Germans 46, yet do not suffer dietary disease from it as we do.
  • Previous student comment: "This material makes me really glad that I don't like cheese."
  • Brief class discussion: What's your cheese strategy?

Writing Discussion 1: Working with the Assignment Rubric and old student writing

  • We will look at the Assignment Rubric for formal writing in the class and a couple of pieces of writing from last semester.
  • 10 minutes:
  • Here is the prompt for SW1 from last semester: What is "food value"? Why is it so hard to determine the value of food(s)? Consider the different ways that food(s) can by valued (nutrition, cost, quality, satisfaction) in formulating your answer. Are the "real" and "fake" food values? Have you found any useful approaches to solving this problem?
  • Please browse to the Sharepoint site, Student Writing Food, SW1 and read two works: Lark and Quokka. Can you see differences in the writing and content quality of these two pieces of student writing?

Nestle, Chapter 1, "From Eat More to Eat Less"

  • this reading gives more detail to the argument as summarized in the Intro. You could say that we are the victims of an industry that succeeded too well!
  • early history of USDA survey of food supply and consumption, 1909. (interesting to note that early studies in the 1890s predate knowledge of vitamins and dietary causes of conditions like beriberi, pellagra, and scurvy.
  • USDA missions: 1. promote reliable and secure food supply. 2. Educate public about food. (Big point: These goals are not in conflict until food abundance ("nutrition transition".)
  • "food groups" approach since early 20th century. War food policy, post-war "food for freedom" promotes sugar and candy. "eat more". Even in 1950's people weren't hitting RDAs in some areas. response of US gov't "eat more". 1960s war on poverty also reinforced "eat more" (recall %33 poverty rate).
  • McGovern committe is the pivot point on "eat more" "eat less". Ancel Keys, explaining increase in heart disease since war, uses comparative data on food cultures with plant based diets. Hits on lipid hypothesis. reduce calories from fat. go low fat.

  • note last page summary: transition in 1980s of not resisting the consensus from the nutritional community, but using it to market nutrients. This coincides with the thesis of "nutritionism". Beware of nutrition marketing. You are often being sold being marketed foods that have added industrial versions of nutritional properties removed in the industrial process.
  • Some inferences from Nestle's narrative: We have had the food politics that you would expect from the historical and social conditions of our culture. The historical conditions of malnurishment and insecure food supplies, along with economic organizations that are motivated to increase profit and production gave us a kind of momentum that produced food in abundance. But it was hard for the political system, having developed political and institutional systems of support for increasing production of food products, and cheap calories, to transition to a world in which the best nutritional advice was to tell people to eat less of many kinds of foods. Meanwhile, food science and the rise of industrial food products gave major food producers a way of contributing to nutrition (ex. fortifying industrial flour and polished rice) or manipulating nutritional advice by altering the chemistry of the product to market on an isolated nutritional claim.

  • fatty acids are chains of C-H bonds with a methyl group on one end (so-called the "omega") and an acid on the other (which bonds to a glycerol)
  • saturated (no spaces in the C-H string), mono (space at the 9th H), poly (spaces after 6) (linoleic acid) and, if after 3, Omega-3 or (alpha-linolenic acid)

  • Food Sources
  • fat from meat is compatible with a healthy diet, but better when taken with fiber and balanced with high ratio of polyunsaturated fats.
  • fish have mostly unsaturated fat [12] compared to red meat [13] or chicken [14] or a Starbuck's caramel brownie [15]!
  • visible and invisible fats
  • Digestion
  • enzymes in small intestine (from pancreas), bile from gallblader, bile emulsifies fat, increasing surface area for enzymes to act.
  • frying foods at high temperatures makes digestion harder and compounds can break down into carcinogenes.

Notes on Practicality

I wanted to move up this lesson on practicality since some of you might want to incorporate practicality goals into your work.

Practicality can be thought of at several levels from the logistics of supplying your diet to sustainability.

  • Here's my initial list of criteria for practicality (on the logistical side of things):
  • You have a practical diet when:
  • you always know what you need at the store, (easy methods here)
  • you rarely waste food, (favors batch process)
  • you don't spend more time preparing food than you can afford, (But how much is that?)
  • your food is portable when you need it to be, (gear, favors bulk form)
  • your meals are flexible when they need to be, (can be delayed if you change you mind about eating at home, can be quick)
  • you have plenty of opportunities to prepare food when you aren't busy, (time shifting meal prep time)
  • but you never have to do it when you are too busy, (measure reserve or quick dinner options)
  • you always have something great to eat and many choices about dinner, (assess need for variety)
  • And, it's all completely affordable. (cost assessment)

Some measurement and goal setting challenges:

  • How much time should you "afford" for food preparation and enjoying. How often? Slow Food thinking supplies some answers to this.
  • How much time do you (should you have) have for making meals? When is that time available to you during the week?
  • What are the main strategies for "time shifting" your meal preparation? for batch preparation?
  • How many different dinners do you need?
  • On any given night, how many different dinners could you choose to make quickly?
  • When you make food from scratch, how often do you make multiple dinners?

Nestle, "Chapter 2: Politics Versus Science -- opposing the food pyramind, 1991-1992"

  • Tells the story of the blocked printing of the 1991 Eating Right Pyramid. Lots of drama and intrigue!
  • Meat and Dairy did not appreciate being "narrowed" in the pyramid.
  • She highlights the USDA mandate (over HEW) after 1977 to produce nutrition information, the tension between that agency and then "HEW" (health education and welfare), (now DHHS) where the Surgeon General was.
  • 53: specific law in 1988 preventing DHHS from issuing nutritional advice that might adversely affect agricultural interests.
  • 54-55: documents the development of the 1988 pyramid. Clearly a multi-year process with lots of professional review.
  • p. 55. Specific design process for the pyramid. Compare other countries approaches. [17]. Compare to current US Dietary Guidelines for 2015-2020. [18] [19]
  • the controversy over the pyramid was mostly about the diminished size of the meat group and it's proximity to the sugar, fats, and oils. If you look at the previous chapter's image of the "Basic Four" design, meat and dairy were "in front" and "on top" of the image. The ensuing controversy had partly to do with gov't officials dodging responsibility for the nutritionists work.

Pollan, Part II of In Defense of Food

  • Part II : Western Diet and diseases of civilization
  • Chapter 1: The Aborigine in all of us
  • Summer 1982 - W. Australia aborigines study -- "metabolic syndrome" -- defined, theorized as signature disease of western diet. [20]
  • O'Dea's results p. 87. Note that she didn't look for a silver bullet, a single factor. Just the diet change.
  • Major premise: Compare us to many traditional diet populations and the difference in diseases profile is stark. It might be the "whole diet pattern" rather than a single imbalance. (The imbalances are symptoms.)
  • Chapter 2: The Elephant in the Room
  • Group of early 20th c intellectuals/doctors (bot 90) noticed absence of chronic disease in populations they traveled to.
  • British doc Dens Burkitt: "Western Diseases" -- diseases attributable to western diet and lifestyle.
  • Pollan chooses the story of Weston Price from this group.
  • Two objections to hyp that Western diet is to blame: disease/race theory (but evidence from mixed ethnicity/race cultures like US suggests not), demographic theory (we live longer, so we get more disease). In both cases, the evidence refutes the claim.
  • Weston Price -- b. 1870. diseases of teeth are effects of Western diet. 1939 major work after global travels looking at teeth. Lots and lots of teeth. kind of an amateur scientists, but collected important data (and seen right by later dental research). hard to find control groups. Price found big differences in Vit A and D. (Note comment about Masai -- . Multiple successful diets for omnivores.) pl 98: note comparison of groups with wild animal flesh and agriculturalists.
  • first to make comparisons of grass fed / winter forage fed animals to find vitamin differences. Example from Pure Eire Dairy
  • decline of nutrition in current vegetables and fruits: [21]
  • Albert Howard 99 -- "father" of organic farming movement; early 20th century; similar time period, making argument against synthetic nitrogen (more later). both pioneers in what would later be seen as an ecological approach to food production.
  • Important: Among first to see a connection between dietary diseases of the food system as part of an "ecological dysfunction". (This is a theme that will occupy alot of our attention in the course.)
  • Chapter 3: The Industrialization of Eating
  • thesis: Calling for a more ecological way of thinking about food. think of food as mutual adaptation of plants and animals to humans. propagation/place in ecology of food chain. example of fruit: ripeness, transportation, high nutrient state. Corn vs. corn syrup. (Note point about possible future humans who could use HFCS. also true of milk in history of agriculture. Pollan doesn't quite give the details on milk. not like a light switching on. Textbook example of gene-culture co-evolution. Selective advantage for those who keep lactase expression going past breast feeding. You can always leave it to natural selection to favor those who can get on with the new diet.)
  • Types of Changes that mark the Western Industrial Diet
  • 1. From Whole Foods to Refined
  • prestige of refined products: prior to roller technology, white rice and flour would be labor added, story of grain rollers 107, Refined flour is the first industrial fast food. Fresh flour lasts days. 108: specific details germ/endosperm, but also local mills, water power. Fortified bread. B vitamins added back in to reduce pellagra and beriberi.
  • 1996: added folic acid.
  • Jacobs and Stefffen study: epidemiological study showing effects of whole grains, but also that groups not eating whole grains, but getting equivalent nutrients did not enjoy benefits. alludes to possible wholism in effects. Sugar intake since 1870's.
  • 2. From Complexity to Simplicity
  • The flip side of food degradation is soil degradation. nitrogen fertilizers. simplification through chemical processing. control. Documented nutrient decline in foods (also article above).
  • simplification of plant species in industrial foods. Again, appearance of greater variety in industrial food store, but products actually represent a small variety plants and animals. 116 for details.
  • details on loss of food crop diversity. [22]
  • conclusion: there may be a false economy in industrial food production. varietals, soil, diversity of food have values that are lost in assessing costs at the retail level and without this knowledge.


  • 3. Quality to Quantity
  • Industrial food system has favored cheap macro-nutrients over cheap whole foods. (whole foods in Italian significantly cheaper.)
  • decline in nutrient content (118-119: review), "nutritional inflation," interest in "phytochemicals" -- seem related to anti-oxidant and anti-inflammatory effects.
  • False food value lesson from "nutritional inflation" : You get a larger variety of X fruit or veg with less nutrition, but it's cheaper. Problem is that you have a limited volume of food intake, so you lose value in the end and possibly compromise nutrition. Simplification of species diversity and monoculture of ag. corn and soy are very efficient producers of carb calories. but then we draw less food diversity by focusing on these two.
  • decline in food nutrient content from food grown in impoverished soil. Calls the result "nutritional inflation" because you have to get greater volumes of food to get your nutrition. some details on how soils matter: growing time affects mineral and vitamin levels (bio-accumulation). some evidence that organic plants have chemicals related to immune responses.
  • "overfed and undernurished"
  • cites Bruce Ames, serious researcher interest in micronutrition and cancer. Interesting theory (unproven) that "satiety" mechanisms are tied to nutrition such that a malnurished body always feels hungry.
  • 4. Leaves to Seeds
  • shift from leaves to seeds decreases anti-oxidants and phytonutrients in our diet.
  • Mentions Susan Allport's The Queen of Fats
  • more seeds tilt in the fat profile of the food product toward O6. less healthy fat. O3 fats spoil faster, so tend to be removed from industrial food. nutritional advice to move toward seed oils didn't originally distinguish O3 from O6.
  • Claims that lipidphobia led us to shift to seed oils (give up butter --which has some 03 fats and move to corn -- which is high in 06 fats) and that led to a change in ratio of O6/O3 from 3:1 to 10:1. note the connection p. 129 between fat profile and sense of "food security" -- interesting digression here. Could we have a deep fear of hunger that still leads us to choose overeating, especially of caloric foods?
  • O3 decline also related to mental health. 130
  • 5. From Food Culture to Food Science
  • shift from reliance on national / ethnic food cultures to science.

Nix, "Proteins"

  • Nature of
  • 20 amino acids, 9 essential; proteins are polypeptides -- chains of amino acids 100s of links long. Proteins exist in specific forms in foods (ex. casein is milk protein) and are broken down by us into amino acids and resembled as protein in metabolism.
  • about 16% nitrogen; protein is a primary source of nitrogen in diet. Nitrogen Balance is shown when excretion of urinary nitrogen occurs as by product of protein metabolism (ratio of 1 g of urinary nitrogen to 6.25 g of protein). Negative nitrogen balance can be a symptom of protein deficiency.
  • Functions of Protein Metabolism
  • Tissue growth/repair: largest component of tissue by dry weight. 75%.
  • Water and pH balance; plasma proteins can exert osmotic pressure to help circulation of tissue fluids (I think this is the "interstitium", but I'm not sure).
  • Proteins can take up acids to contribute to blood Ph management.
  • Metabolism, transport, immune system, energy system. Wide range of functions here. We have already met "lipproteins" that help carry fats around. Here you learn that enzymes, transport agents, and hormones also have protein structures.
  • Proteins also help make white blood cells, so support your immune system.
  • Food Sources
  • Complete proteins mostly from animal sources, including dairy, cheese.
  • Soy is the only complete plant protein.
  • Completing proteins: p. 52. also compare links ceci beans [[23]], lentils [24], peanut butter [25] and sesame seeds [[26]]. Sirloin steak [27]. Note how you can use the site to find complementary foods for foods with relatively low amino acid scores.
  • advice on vegetarian diets -
  • Digestion
  • Occurs in stomach and small intestines
  • Recommendations
  • 10-35% of calories from diet
  • .8g / Kg of body weight.
  • Overconsumption of protein by Americans, p. 59 Men at 181% of DRI
  • Debates about protein quality. [28]

Personal Protein Tally

  • We've used a "profile" metaphor to talk about carbs and fats (profiles of complexity in carbs and fat saturation for fats), but with proteins, it makes sense to "tally" or add up your intake, while watching for protein quality.
  • Calculate your protein goal in grams. 150 lbs. = 68kg x .8 = 54grams RDI /day
  • Go through your diet and look at the amounts of good protein in your day. How hard is it to meet your goal?

Short Writing Assignment #1: 600 words

  • Stage 1: Please write an 600 word maximum answer to the following question by Monday, February 25, 11:59pm.
  • Topic: What do critics of industrial food mean by "industrial food" and what are the most significant and authoritative criticisms of industrial food and the industrial food system. Are there healthy industrial foods?
  • Advice about collaboration: I encourage you to collaborate with other students, but only up to the point of sharing ideas, references to class notes, and your own notes. Collaboration is part of the academic process and the intellectual world that college courses are based on, so it is important to me that you have the possibility to collaborate. It's a great way to make sure that a high average level of learning and development occurs. The best way to avoid plagiarism is to NOT share text of draft answers or outlines of your answer. Keep it verbal. Generate your own examples.
  • Prepare your answer and submit it in the following way:
  1. Do not put your name in the file or filename. You may put your student id number in the file. Put a word count in the file.
  2. Format your answer in double spaced text in a 12 point font, using normal margins.
  3. Save the file in the ".docx" file format using the file name "SW1".
  4. Log in to courses.alfino.org. Upload your file to the Q&W dropbox.
  • Stage 2: Please evaluate four student answers and provide brief comments and a score. Review the Assignment Rubric for this exercise. We will only be using the Flow and Content areas of the rubric for this assignment. Complete your evaluations and scoring by Friday, March 1, 2019, 11:59pm.
  • Use this Google Form to evaluate four peer papers. The papers will be in our shared folder, but please do not edit or add comments to the papers directly. This will compromise your anonymity.
  • To determine the papers you need to peer review, I will send you a key with animal names in alphabetically order, along with saint names. You will find your animal name and review the next four (4) animals' work.
  • Some papers may arrive late. If you are in line to review a missing paper, allow a day or two for it to show up. If it does not show up, go ahead and review enough papers to get to four reviews. This assures that you will get enough "back evaluations" of your work to get a good average for your peer review credit. (You will also have an opportunity to challenge a back evaluation score of your reviewing that is out of line with the others.)
  • Stage 3: I will grade and briefly comment on your writing using the peer scores as an initial ranking. Assuming the process works normally, I will give you the higher of the two grades. Up to 14 points in Q&W.
  • Stage 4: Back-evaluation: After you receive your peer comments and my evaluation, take a few minutes to fill out this quick "back evaluation" rating form: [31]. Fill out the form for each reviewer, but not Alfino. Up to 10 points, in Q&W.
