  • 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"?

Assigned

  • Sonnenbergs, C 5, "Trillions of Mouths to Feed" (111-136)
  • Sonnenbergs, C 7, "Eat Sh*t and Live" (163-185)
  • Nestle, "Introduction: The Food Industry and 'Eat More,' from Food Politics", 2013. (1-30).
  • Student Writing: Food biographies


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",
  • 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)
  • 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.

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. [What is relationship between ownership type and production, capitalization, industrialization? Digress to woofing. More traditional farm structure might focus on sustaining real income rather than meeting investor expectations.]
  • 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. (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)
  • 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.
  • Social trends: female labor market participation, changes in perception of "cooking". Scratch cooking associated more with sub-cultures.

Assigned

  • 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. 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):
  • [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.
  • 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. [[4]]
  • Frosted Mini-Wheats became "brain food". fraudulent research. 91-92 Commercial in this NPR story Also, check out these oldies. [5]
  • 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.
