Gastrpod, "The End of the Calorie"
- Sanctorio Sanctorius - 1600’s Padua - 30year practice for weighing inputs and outputs.
- 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. Visit to contemporary calorimeter. USDA site: Converted walk in cooler. Implication that the woman with the sewing machine “made a mess”?
- 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):
- 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.
Andrews, Chapters 1 & 2, The Slow Food Story
Chapter 1, "Politics in Search of Pleasure"
(This wasn't assigned for us, but I have these notes to share:)
- context for slow food: social movements of the 60's and 70's. (Italian counter-culture.)
- low power radio stations common means: Radio Bra Onde Rosse.
- politics at Club Tenco, also the pursuit of pleasure.
- revival of traditional festivals: the singing for eggs (Cante i'euv)
- 1982 incident: Montalcino Sagra del Tordo (thrush) Mention Arci clubs.
- formation of an "Arci Gola" (appetite)
- projects: Gambero Rosso, wine guides, Osterie d'Italia, guides to osterie.
- 1986: wine poisoning scandal. McDonalds opens in Rome at Spanish Steps.
- Slow Food Manifesto
- parallel movement in US embodied on story of Alice Waters, founder of Chez Panisse. Pollan also finds sources of these ideas in 1960s US counter-culture.
- Eco-gastronomy -- (a great sub-field of food study, by the way! cf. Dan Berber, The Third Plate) and the "politics of aesthetics" (only partly in line with Marxism). (So Carlo Petrini is another candidate for Gramsci's authentic intellectual.)
- Projects: international food exhibitions, then Terra Madre (2004), related movements in Germany (Greens)
- slow food also has a conservative dimension.
Chapter 2, "The Critique of 'Fast Life'"
- some key dates: McDonald's in Rome, 1986, incident between the two arci chapters (a moment in which politics and gastronomy interact to great effect!).
- critique of "productivity culture"; efficiency vs. frenzy; idea that you need to live faster because other things are accelerating (financial trade volume, sale, news cycles, social media posting and communication)
- critique includes resistance to corporate formations and rationalizations (degradation) of taste. Slow Food is tied to leftist politics, but also has a US upper middle class "face" in the US site. 
- Castell's theory of time-space compression -- capitalism more and more about speed of transactions. circuluation of capital. (on edge of a big discussion about the future of work - piece work is coming back).
- Counter view of Charles Leadbeater and others: fast culture is the answer, the problem is that we have all of these institutions from the 19th century and earlier slowing us down.
- Ritzer's "McDonaldization of Society" -- "globalization of nothing" (social forms centrally conceived, centrally controlled and lacking in context).
- Schlosser, Fast Food Nation:
- 1970 6 billion on fast food; ("million" in the text is a mistake)
- 2001 110 billion
- 2010 200 billion (not in text)
- British "trolley towns"; American suburbs. globalization of construction and architecture.
- Petrini on slowness: p. 39 read
- Slow cities: features of slow cities

Microbiome Movie Notes
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
- 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 --
- 22-30 - Cultural History and History of Science on Bacteria
- 60-70's: Abaigail Salyers: early pioneer, 2008: Human Microbiome Project
- Contemporary research: gnotobiotic mice. early fecal transplant studies of [Dr. Jeffrey Gordon].
Montgomery and Bilke, "What Your Microbiome Wants for Dinner" (recommended)
- Digestion Basics
- good introduction to digestion.
- Microbiota (M) like a pharmacy.
- Grain Wreck
- Chemistry of Typical cereal crop seed --
- espouses what I'm calling the "consensus healthy diet" - movement away from industrial processed food.
Philosophical Implications of the Microbiome
- The Microbiome research we are reading seems to have implications for the following course research questions:
- 1. What is food?
- 5. What are the challenges of nutrition science as a field of knowledge and what is the state of knowledge about nutrition, broadly?
- 6. What is a nutritious diet?
- 10. How should I critically assess my own food practices in light of my understanding of the nature of food and food culture?
- Here are some possible theoretical claims for you to evaluate in terms of their plausibility and their own implications:
- Your food doesn't just feed you.
- Mental health is influenced by the health of our M.
- We have co-evolved with our Microbiome.
- The interic nervous system is an ecology.
- In small group discussion, consider how information about the Microbiome might change your approach to questions like "What is Food?" Then look over the proposed philosophical implications above. Are they too strong? Warranted? Do you have sceptical doubts about using this research to alter your view of these research questions?
OCT 2: 5
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. pets help with our microbiota.
- Microbiota mechanisms:
- direct response to diet, "recyclers",
- 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. Overconsumption of refined carbs.
- Carb chemistry/metabolism basics -- 120: also in our nutrition textbook chapters. Note unique types of saccharides in particular foods: read 121 and 126; insulin resistance.
- Measuring MACs - the authors acronym for Macrobiotically Available Carbohydrates. - no standard measure of dietary fiber (note discrepancies from above.)
- 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 better predictor of disease than obesity.
- Gordon's famous 2013 FMT mouse research: need M and M-supporting diet. Note caveat 129. Can't just benefit from the microbes alone.
- 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.
- What about the Inuit?
- What about excess gas?
- 135: Note their dietary advice.
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.
- IBS and IBD - 177:
- 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.
Montanari, "Food is Culture"
- Creating One's Own Food
- q. 3: roughly, now that we're in a postindustrial age, we look at agriculture as "natural" and traditional, but from the perspective of those adopting, it wasn't. - but they experienced ag as a break from nature. against nature, but also a breakthrough and innovation. ...gave us power to rule nature (later ideas about space and time).
- demography of agriculture is amazing.dates for ag in diff regions (5), "invention of agriculture...matter of necessity tied to population growth"
- cites Franz Braudel, who made a version of this thesis. Agriculture organized everything (roughly). see list. economy, religion (make side point about warrior / ag gods). Civitas and civilitas depend upon agriculutre!
- Bread, breadeaters, marks break from nature. Bread is an invention from nature (sidepoint: can sustain life, man can live on bread alone, it just isn't pretty.). Interesting reference to mythology of bread and woman in Epic of Gilgamesh (short term research oppportunity).
- Fermented drinks - like bread, break from nature.
- germ idea about culture: culture is produced where tradition and innovation intersect
- Even Nature is Culture -
- two oppositions: 1. ag and hunt/gather goes through plant and animal kingdom. but 2. sedentary/nomad favors plant over animal (in fields vs. forest opposition, plants are identified with culture, hunting with nature)
- gods/myths of agricultural societies: stories of Persephone, rice in asian narratives, corn in Mayan legend. hunting practices treating bones of animal as sacred, basis for rebirth. Germans have their grand Miale!
- thesis: opposition between nature and culture somewhat fictitious. something like: civilized man uses nature (food structured) in the primary myths to separate him/herself from nature.
- p. 11: difference btween Greco-Roman and German food systems. Germ of European food system in the clash between these cultures (note that Romans saw German meat culture as barbaric. Romans would have eaten meat, but not as primary food (note, later, Christian calendars with meatless and fasting days). Christianity coming from Med culture, has bread and wine as liturgical symbols. Unification of these cultures produces European food culture, balancing bread and meat. Implications for gastronomy.
- Playing with Time
- no seasons in Eden or Land of Cockainge.
- Food culture developed by prolonging and stopping time, through species variation and food storage. examples 14-15. "man made putrefaction a means to a useful end" cheese, cured meats.
- Playing with Space
- goal of transcending spatial limits to food, transpo. Nice story from the Mantuan court of Gonzaga. "good horse and a full purse". involves concept of "terroir".
- food systems are not nec. harmonious (esp. given what is at stake in a food insecure world). Medieval system was a class based system of control of food production. Peasant rebellions over restricing forest access. Robin Hood. famine image: scene of farmers at the city gate starving. conflicts between lords also about food, cities taxed area villages in food. Irish food famine of 1846 due to English control of food. (can't live on potatoes).
- examples of movements of food in global trades cultures. For Columbus ( int. term "Columbian exchange") and age of conquest, exploitation was avowed purpose.
- Original text in "bio-history".
OCT 4: 6
Pollan, In Defense of Food, first 4 chapters of Part 1
- background on previous work and personal food history.
- 5: example of failure of advice on fat and cancer, coronary heart disease. Failure of claims about fiber not reducing cancer risk., also on value of fish.
- best to understand confusion on nutrition as result of interaction of food industry, gov't and journalism.
- claim for Part One: most of the nutritional advice of the last 50 years has made us less healthy.
- surprising claim: It's a dangerous idea to think that food is just about health. orthorexics.
- 10: Western Diet defined. Four of the top ten causes of death today are chronic diseases with well-established links to diet: coronary heart disease, diabetes, stroke, and cancer. Even after adjusting for longevity. Note: You could define it epidemiologically or in terms of principle traits.
- goal: advice for enjoying food.
- Chapter 1 - From Foods to Nutrients
- food disappearing in favor of "nutrients" - a kind of reductionism.
- William Prout, early 19th division of macronutrients into Protein, Carb, and Fat. Justus von Leibig, also studied soil, imp. or minerals.
- 1912: Casimir Funk, "vitamines" - goes back to "vitalism", also "amines" because nitrogen based.
- McGovern Committee: important ideological moment: part of the story starts in 1977, with the first Fed comm on nutrition. blow back on recommendations 23. This led to a strategy of not referring to foods directly in terms of "more or less" but nutrients. Also, good foods reduced to nutrients.
- also from 1950's "lipid hypothesis" - that fats from meat and dairy were responsible for much dietary disease.
- Chapter 2 - Nutritionism Defined
- Gyorgy Scrinis -- 2002 claim.
- Nutritionism puts the food scientists in charge. leads to thinking about foods as "good" or "bad" based on their nutrients. you find this in the history of nutrition. 29ff. Liebig made "protein" a master nutrient. Others, like Kellog and Fletcher, would promote carbs. Good place to see limits of nutritionism is in baby formula. Still no match for the real thing.
- Chapter 3 - Nutritionism comes to Market
- nutritionism works well with marketing of food. margarine, for example. starts as cheap fat, but then marketed as healthier. industrial foods can be redesigned as nutrition fads change.
- early history of food adulteration. Sinclair's The Jungle, 1938 Food, Drug, and Cosmetic Act. Objections to "imitation" rule. (note other controversies: milk, real). Thrown out in 1973. If an imitation food is nutritionally similar to the food it imitates, it doesn't need to be called imitation. Opened the door to lots of chemical substitutes.
- Chapter 4 - Food Science's Golden Age
- diet fads tend to favor foods that can be re-engineered. Some of that can be done with animals by feeding them differently, but mostly this favors industrial food over whole foods. Note on taste of leaner corn-fed beef. Arguably a decrease in satisfaction.
Group Writing Exercise
- What is nutritionism? Does it makes sense to say that it contributes to an ideology about food? Express both majority and minority views from your group. 300 words.
Montanari, "Food is Culture" "Fire > Cooking > Kitchen > Cusine > Civilization
Fire > Cooking > Kitchen > Cuisine > Civilization
- cooking essential to human being. (note other resources) . Western story of Prometheus (30), the hearth identifies human being (abode).
- Not true that cuisine is only about cooking. raw food methods. Chinese critic of western gastronomy as based too much on cooking. meanings of "Cucina". transition from womens' domain to men's.
Diamond, Ch. 10, "Agriculture's Mixed Blessings" (recommended)
- Old "progressivist" view
- Ants practice agriculture and something like animal husbandry
- Details about the spread of agriculture
- Advantages of hunter gatherer lifestyle
- short work week, more leisure
- better nutrition (in some comparisons)
- no impact from crop failures
- paleopathology: what you tell from old bones and cookware
- health evidence from early adoption of agriculture
- height, nutrition, cavities, anemia, tb, syphillis, mortality
- low carb, varied nutrients
- class structures emerge after agriculture: diff outcomes dep. on class
- sexual inequality
- other differences that sustained agriculture
- increased population density made hunt/gather politically vulnerable
- hunt/gather requires lots of room
- agriculture created society that could produce sophisticated art (churches).
OCT 9: 7
Two famous restaurants started by Chef/food activits.
Barber, "Intro and Ch 12"
- Story of Eight Row flint corn at Blue Hills. sig. "varietal restoration" "heritage cultivation"
- Story of the summer of corn at Blue Hills Farm when Barber was a kid. Note diffs.
- planted in "Three Sisters"
- polenta not typically thought of as high flavor experience, but in this case it was.
- Some detail on Blue Hills.
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 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. (Note: Not just more protein. More of everything! Revise our protein hyp.)
- 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. Advertising spending on industrial food, using philanthropy for branding, new food products (25)
- Social trends: female labor market participation, changes in perception of "cooking". Scratch cooking associated more with sub-cultures.
OCT 11: 8
Pollan, Part II of In Defense of Food
- Part II : Western Diet and diseases of civilization
- Chapters 1 and 2
- Summer 1982 - W. Australia aborigines study -- "metabolic syndrome" -- defined, theorized as signiture disease of western diet.
- 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.)
- Group of early 20th c intellectuals (bot 90) noticed absence of chronic disease in populations they travelled to. Pollan chooses the story of Weston Price from this group.
- Two objections to hyp that Western diet is to blame: disease/race theory, demographic theory (live longer). 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. made comparisons of grass fed / winter forage fed animals to find vitamin differences.
- Albert Howard -- 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.
- Chapter 3
- 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
- 2. From Complexity to Simplicity
- 3. Quality to Quantity
- "overfed and undernurished"
- 4. Leaves to Seeds
- O3 decline also related to mental health. 130
- 5. From Food Culture to Food Science
OCT 16: 9
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 onditions like beriberi, pellagra, and scurvy.
- "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. (connect this discussion to Pollan, 40-50)
- 43: Surgeon General's contribution -- 1979 first attention to processed foods nutritional value, publication Healthy Peoplerecommended less red meat (last time Fed Gov't would do that). Instead, switch to lean meats.
- back to USDA guidelines: 1985, first mention of maintaining ideal weight. "avoid too much" instead of "eat less". 49: consensus among nutrtitionists in late 1980s. Series of authoritative reports against high fat meat. consensus on limits of calories from fats, salt. consensus on need to restrict overall calorie intake as well.
- 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".
- 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 to transition to a world in which the best nutritional advice was to tell people to eat less of many kinds of foods.
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. 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.
- 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.
Small Group Discussion
- Considering this political history, what part of government should have responsibility for informing the public about diet and health?
- Review the various ways of picturing a healthy diet including some of the other governments' approaches and "My Plate" (see Guidelines or )
OCT 18: 10
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.
- 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. []
- Frosted Mini-Wheats became "brain food". fraudulent research. 91-92 Commercial in this NPR story Also, check out these oldies. 
- Kellogg even tried comparing kids who ate Mini-Wheats to kids who skipped breakfast!
- Interesting. You could argue that we entered a "post truth" era in the food industry before politics.
Zepeda, Lydia, "Carving Values with a Spoon"
- Zepeda gives us a great example of philosophy of food writing that addresses many of the kinds of issues we have identified in the course so far. Note how she moves us off a "binary" of "consumer responsibility" vs. "regulatory state"
- How do you assess responsibility? individual vs. food industry. Her thesis: context affects choice.
- Values of US food context: lots of cheap calories, low % of spending on food, little concern about conditions of production. (note her point that we are using public money to do this. In a way, the opposite of a Nanny state might be one in which corporations maximize profit from food by degrading the quality of food.)
- some stats: food away from home up to 42% of food expenditures. 2004.
- national policy and cultural values influence by pioneer experience (p. 36), which often involved food insecurity and starvation. (Mention 1493- Thanksgiving story). Also might explain bias toward storable foods.
- postwar food culture characterized by industrial versions of pre-war diet. frozen dinners, more desserts, bigger serving sizes tracked increases in wealth.
- industrial deskilling -- "end of cooking"; labor participation from women increases.
- Eating in the New Millenium - focus on palette and how we spend our time.
- 1990s-2000s -- note p. 39. Interesting claim: we don't want real cuisine, but a branded version of it we can trust.
- 30 minutes a day on food prep and clean up. Simple Diet Plan: 70-90 minutes.
- wages in the food and restaurant industry are among the lowest.

Pollan, In Defense of Food, Part 3
- Chapter 1
- concedes need to use science in spite of some ideology in nutrition science (nutrient fads, for example); big evidence about Western Diet is still epidemiological.
- hard to avoid industrial food if meat is raised on a Western diet (but not impossible. What does a whole food diet cost?)
- "eating algorithms" - interesting concept. rules of thumb for choosing food.
- Chapter 2: Eat Food
- Use grandma's standard; if it can't rot, it's not food. Ingredients; products with health claims; stay on the edges of the supermarket, avoid the commercial supermarket... (easier to just eliminate most processed foods). (Interesting to note how much smaller a food store can be without so much industrial food.)
- Chapter 3: Mostly Plants, especially leaves.
- leafy plants especially (current guidelines distinguish types of plants by color and starch). Gives the anti-oxidant theory (which seems to be holding up well)
- try not to isolate the seed from the plant. (Kind of like isolating the juice from the fruit.) Eat the whole thing.
- "You are what you eat eats too" - you can't have healthy animal food if you feed the animals a Western Diet. (disgress on Andrew Smith argument -- can't be vegetarian). Attention to soil.
- Pro: wild food, supplements, traditional cuisines (typically nutrient dense and balanced), scepticism about new foods, don't look for "magic" diets, enjoy food.
- Chapter 4: How to Eat
- European food culture: behaviors -
- Pay More, Eat Less - not just trade offs, but actually asserting control of amounts.
- Is save meal prep time a false convenience? economist study using concept of "time cost" of eating. Microwaves reduce that, for example.
- Eat Meals vs. "continuous eating" (some issues here: family units don't characterize your part of the life span at the moment. Ideas?)
- Some things to add to Pollan's list:
- potato chips comparison: Lay's vs. Kettle Brand
Small Group Discussion
- 1. Using the continuum we developed between "Ultra-industrial and Ultra-Organic/Saporific locate some of your favorite foods. Where are they on the scale? Which ones could you imagine "trading up" in cost and quality? Compare with others in the group?
- 2. Recall a time when you or a group of friends or family last made a "big deal" out of eating a meal together? Was that part also satisfying? Why? How do the satisfactions of a meal with others compare to those of eating alone? What do you or might you do to make a "big deal" out of eating alone? Is treating food as sacred going too far?
- 3. Evaluate Pollan's "Pay more, eat less" advice in the context of our discussions of "food value" and monthly food budgets. Does it make sense?

Ethical Diets #1
Age of Slaughter vs. Natural Life Span
- Note that the more symmetrically you see animal and human interests, the more likely this information is to be problematic.
- Pigs: Slaughtered at 6 months young; Natural life span: 6 to 10 years
- Chickens: Slaughtered at 6 weeks young; Natural life span: 5 to 8 years for those birds bred as "egg layers" such as Rhode Island Reds; 1 to 4 years for factory layer breeds such as leghorns; and 1 to 3 years for "meat" breeds.
- Turkeys: Slaughtered at 5 to 6 months young; Natural life span: 2 to 6 years
- Ducks/Geese: Slaughtered at 7 to 8 weeks young; Natural life span: domestic ducks: 6 to 8 years; geese from 8 to 15 years.
- Cattle: “Beef” cattle slaughtered at 18 months young; dairy cows slaughtered at 4 to 5 years young; Natural life span: 18 to 25+ years
- Veal Calves: Slaughtered at 16 weeks young; Natural life span: 18 to 25+ years
- Goats: Slaughtered at 3 to 5 months young; Natural life span: 12 to 14 years
- Rabbits: Slaughtered at 10 to 12 weeks young; Natural life span: 8 to 12+ years
- Lambs: Slaughtered at 6 to 8 weeks young for “young lamb” and under 1 year for all other; Natural life span: 12 to 14 years
- Horses/Donkeys: Slaughter age varies; Natural life span: 30 to 40 years
Singer and Mason, "What Should We Eat"
- This reading gives you an overview of value oriented questions in diets.
Singer and Mason, "Ch 4, Meat and Milk Factories"
- "Jake" refers to real interview subject. Book framed around several distinct diets of actual people and then journalism and ethics layered in.
- 90% fewer farms producing 103 million pigs, up from 69 million in 1975.
- Pig farms environmental footprint dominated by excrement production. 4x human/day.
- Evidence against sow stalls in EU investigation.
- difficulty sourcing to particular dairy, even specialty brand. Cf. Pure Eire dairy 
- air pollution from dairy and cattle production.
- Beef cows
- Australian ranch: example of "happy meat" -- like "crowd cow"?
- Additional sources:
Fischer, Bob, "Arguments for Consuming Animal Products"
- This article considers the ethical possibilities for arguing either against prohibitions on meat eating or in favor of meat eating.
- "man on the street" intuitions: health, natural, nice, normal. Not very promising starts.
- organization: survey of arguments:
- 1. "ought" or "may" eat meat;
- 2. practices: animal friendly ok; industrial ok; insects, oysters, roadkill, wild animals
- Utilitarians arguments favoring consumption of animal products (or problems with simple utilitarian arguments against meat)
- might focus on hunting or eating a whale (loss of utility of one big animal vs. pleasure of many)
- Rights based arguments
- Cuneo offers another version of this kind of argument, not killing is too great a burden on rights.
- New Speciesism and Agrarianism
- Environmental and Agrarian approaches
- Summary of key insights of attempts to justify animal consumption
- 1. Don't forget that plant agriculture involves killing animals too.
- 2. Don't forget about insects, mollusks, bivalves and road kill.
- 3. Rights arguements don't yet tell us what we can or cannot do to animals.
- 4. Ahimsa is fine, but we might need to accept the violence of getting nutrition from the world.
