I’ve just heard about the new Netherlands food guide.  It emphasizes sustainability.  According to an article in National Geographic’s The Plate,

The Netherlands Nutrition Centre says  it is recommending people eat just two servings of meat a week, setting an explicit limit on meat consumption for the first time [but see added comment below].

Here’s what the Netherlands food guide looks like.

Google translator calls this a pyramid, and explains: “Moreover, the Pyramid helps you eat more environmentally friendly broadly.”

Ours, of course, looks like this.  I’m guessing the USDA is working on a new food guide in response to the 2015 Dietary Guidelines.  These do not mention sustainability at all—the S word.

If you want to check out food guides m other countries, see FAO’s pages on food-based dietary guidelines.  You can search the site by regions and countries.  Fun!

Added comment: A reader from Amsterdam, who obviously speaks Dutch better than Google translator, and who also is well versed in the Dutch nutrition scene, writes:

Sustainability is indeed an important concern in the new Dutch food guide. However, the recommendation for meat is not ‘two servings per week’, but two servings of red meat and two servings of white meat (chicken), for a total of four per week. One serving is 100 gram or 3.5 oz. of meat. Diehards may add a third serving of red meat; 300 g of red meat (11 oz) plus 200 g of chicken (7 oz) per week is considered the absolute limit.

The fish advice has been reduced from twice to once a week because environmental concerns were thought to outweigh the small health benefit of a second weekly serving of fish.

Is fat really good or bad and, one way or the other, is it really back?

Food Navigator-USA has an interest in fats from the perspective of companies that use them in food processing.  Here’s what it says:

Fats are often classed into good, bad and ugly categories. But do consumers know which are which, and how can manufacturers help increase consumption of the healthier variety (MUFAs and PUFAs) and reduce trans- and saturated fats (and that’s assuming that saturated fats really are the bogeyman many dietitians have made them out to be)?

Protein is hot, sugar is public enemy #1, and fat is back (so the trend-watchers say). But when it comes to good, bad and ugly fats, does everyone agree on which are which? Check out our gallery of insights from consumers, industry stakeholders, and the 2015 Dietary Guidelines Advisory Committee…

After all the talk yesterday about the Dietary Guidelines’ advice to cut down on sugar, and our sadness at the passing of Sidney Mintz who wrote Sweetness and Power, it’s good to consider just why we like sugar so much.  Oxford University Press has an encyclopedia on Sugar and Sweets.  But this weekend, for a short and sweet reminder, consider this contribution to the genre.

Andrew F. Smith.  Sugar: A Global History. Reaktion Books, 2015.

This is one of Andy Smith’s entries in Reaktion’s Edible series of small, brief, lavishly illustrated books devoted to a single food or beverage.

Andy discussed the genesis of this book in an e-mail memorial to Sidney Mintz.

Sid Mintz had an influence on my professional life as well. In the early 1980s I decided to use sugar as a vehicle to write a history of the world.  It was going to be a three volume work: one volume on Southeast Asia/India and the ancient world; one on the Middle East/Mediterranean in the Middle Ages/Renaissance; and one on the Americas and the modern world. I acquired and located thousands of potential books/articles and these were likely just a small portion of the material I assumed would be necessary to examine.

I continued plugging away until Sid published Sweetness and Power (1985), I assumed publishers would not be interested in another book on sugar history, so I decided to wait a couple years for it to go out of print before I resumed work on my sugar project.  So in the interim I decided to write a book on the history of the tomato, which was published in 1994. Then one topic led to another and sugar ended up on the shelve…

When I dined with Sid in 2001, I told him my sugar story, and asked him if he’d take his book out of print so I could write a sugar book. He laughed, and told me what I knew to be true– the topic of sugar history was big enough for many books.

I finally got around to writing Sugar: A Global History, which was published last spring. Rather than the three volume extravaganza I had planned, it ended up one of the shortest books I’ve ever written.

Maybe, but lots of that information got into it, wonderfully written, and beautiful to behold.

Jason Huffman, Helena Bottemiller Evich, and Jenny Hopkinson of Politico Pro Agriculture have published their end-of-year assessment of game-changing events in food and agriculture policy last year.  Here’s their list:

• Avian flu blew up the U.S. egg industry.
• The Trans-Pacific Partnership deal got done.
• The battle over the Dietary Guidelines turned even nastier.
• The FDA banned most uses of trans fat.
• The FDA said a genetically engineered fish is safe to eat.
• The EPA released its final Waters of the U.S. rule, inciting the wrath of multiple industries, states and lawmakers.
• A federal judge sent peanut company executives to jail for decades for their part in a giant salmonella outbreak.
• The FDA released major rules to promote the safety of produce and imports.
• The FDA doubled down on added sugars on food labels, proposing daily values for the listings.

I’ve discussed most of these on this site (all except Waters of the US).

I can’t wait to see what this year brings—more of the same, for sure, but what else?  Stay tuned.

Thanks to Helena Bottemiller Evich of Politico Pro for doing the homework on food issues covered by the omnibus spending deal just agreed to by the House.  Here’s my quick summary of her summary.

• GMO labels: the effort to preempt local and state GMO labeling initiatives failed as a result of the efforts of 30 representatives who opposed the measure.
• Country of origin labels repealed: the meat industry scores a win in the House vote to repeal the measure.
• Dietary guidelines: I discussed this one in yesterday’s post.  The House wants to block their release on the grounds that they are not sufficiently scientific (translation: the meat industry doesn’t like advice to eat less meat).
• The Clean Water Act: it survives.
• GMO salmon: it will have to be labeled.
• Food safety funding: up more than $132 million to $2.72 billion in discretionary funding. This is a big win for the FDA. It also proposes $1 billion for the USDA’s Food Safety and Inspection Service, also above the president’s request.
• Trans fat ban”: delayed until FDA’s formal rules go into effect in June 2018.
• School lunch flexibility: Riders allow schools to ignore whole grain requirements and block sodium restrictions pending further research.
• Chinese chicken out of schools: Prohibits purchasing chicken that was processed in China for school meals or other federal nutrition programs.
• More kitchen equipment: Schools get another $30 million for school equipment grants.
• Horse slaughter: Banned.

Caveat: this is the House deal only.  The House has to vote on the actual bill, then the Senate.  Then the two bills need to be reconciled and the President needs to sign.  Until then, everything is up for grabs.

In case you haven’t been following this saga, I’ve been collecting studies funded by food companies since last March and posting them according to whether the results do or do not favor the sponsor’s interests.  So far, I’ve reported 80 that do, versus 6 that don’t (although I have a couple more saved up for posting soon).

The point of this exercise is to demonstrate that sponsored studies are far more likely to favor the interests of the sponsor than are studies funded by government agencies or foundations, and to argue for more independent funding of food and nutrition research (see my recent Viewpoint on this topic in JAMA Internal Medicine).

Here are five more examples.

Is consuming yoghurt associated with weight management outcomes? Results from a systematic review. J Eales, I Lenoir-Wijnkoop, S King, H Wood, F J Kok, R Shamir, A Prentice, M Edwards, J Glanville, R L Atkinson. Int’l J Obesity 2015 ahead of print.

• Conclusions: Yoghurt consumption is associated with lower BMI, lower body weight/weight gain, smaller waist circumference and lower body fat in epidemiological studies. RCTs [randomized controlled trials] suggest weight reduction effects, but do not permit determination of a cause/effect relationship. Well-controlled, adequately powered trials in research and community settings appear likely to identify a modest but beneficial effect of yoghurt consumption for prevention of weight gain and management of obesity. The ready availability of yoghurt (a nutrient dense food) and its ease of introduction to most diets, suggests that educating the public to eat yoghurt as part of a balanced and healthy diet may potentially contribute to improved public health.

Red Meat and Colorectal Cancer: A Quantitative Update on the State of the Epidemiologic Science.  Dominik D. Alexander PhD, MSPHab*, Douglas L. Weed MD, PhDc, Paula E. Miller MPHb & Muhima A. Mohamed M PHd. J Am College Nutrition 2015;34: 521-43.  DOI:10.1080/07315724.2014.992553

• Conclusion:  The state of the epidemiologic science on red meat consumption and CRC [colorectal cancer] is best described in terms of weak associations, heterogeneity, an inability to disentangle effects from other dietary and lifestyle factors, lack of a clear dose-response effect, and weakening evidence over time.
• Funding: This manuscript was partially funded by Meat & Livestock Australia (MLA). MLA did not contribute to the writing, analysis, or interpretation of study findings.
• Comment: The conclusion of this industry-funded study contradicts the findings of the WHO International Agency for Research on Cancer, which finds processed meats to be carcinogenic, and red meat to be a probable carcinogen.

The challenges of nutrition policymaking. Joanne Slavin.  Nutrition Journal (2015) 14:15 DOI 10.1186/s12937-015-0001-8.

• Thrust of paper: As every DGAC [Dietary Guidelines Advisory Committee] wants to be bold and set new direction, nutrition science would support that first we must do no harm with our dietary guidance. Moderation and variety must be kept front and center…A suggestion that all Americans should reduce sodium intakes is not sound and is potentially dangerous. Targeting certain foods and beverages, including chocolate milk, processed meats, added sugars, and even the noble potato as villains in the nutrition wars is not a science-based strategy and may need to be countered on the political front if appointed scientific review committees continue to take this approach.

Does low-energy sweetener consumption affect energy intake and body weight? A systematic review, including meta-analyses, of the evidence from human and animal studies PJ Rogers, PS Hogenkam , C de Graaf, S Higgs, A Lluch, AR Ness, C Penfold, R Perry, P Putz, MR Yeomansand DJ Mela.International Journal of Obesity (2015), 1–14 10 November 2015; doi:10.1038/ijo.2015.177

• Conclusions: Overall, the balance of evidence indicates that use of LES [low-energy sweeteners] in place of sugar, in children and adults, leads to reduced EI [energy intake] and BW [body weight], and possibly also when compared with water.
• Conflict of interest: Peter J Rogers has received grants from Sugar Nutrition, UK in support of research on the effects of sugar on human appetite. Cees de Graaf has received grants from the Dutch Sugar Bureau in support of a study on brain responses to sugars and low energy sweeteners. Suzanne Higgs has received a grant from Canderel in support of research on the effects of low-energy sweeteners on human appetite.

The Physicans Committee for Responsible Medicine (PCRM), a group advocating against use of animals in research but for vegetarian and vegan diets, has started a campaign to restore egg-and-cholesterol recommendations to the Dietary Guidelines for Americans.

Eggs are the largest source of cholesterol in American diets.

The campaign involves billboards like this one, in six locations in Texas:

It also involves a new organization (truthaboutegg.org) with an interactive website on a dozen issues related to egg production and consumption.

The one that particularly caught my eye was #5.

A 2013 review suggested that high-cholesterol foods have only a modest effect on blood cholesterol. Of the 12 studies it relied on, 11 were industry-funded.

In a letter to Congressman K. Michael Conaway (Rep-TX), Dr. Neal Barnard, PCRM’s president, wrote:

This week, billboards near your Texas offices will alert you to the dangers Americans face if cholesterol warnings are removed…Eggs are the leading source of cholesterol in the American diet.  A report (which I’ve included for your review) in the autumn 2015 Good Medicine magazine finds that this recommendation may have been influenced by egg-industry-funded cholesterol research. America’s heart disease and diabetes epidemics will continue unabated if the egg industry succeeds in its efforts to get cholesterol warnings out of the guidelines.

The 2015 Dietary Guidelines Advisory Committee (DGAC) said this about dietary cholesterol.

Cholesterol. Previously, the Dietary Guidelines for Americans recommended that cholesterol intake be limited to no more than 300 mg/day. The 2015 DGAC will not bring forward this recommendation because available evidence shows no appreciable relationship between consumption of dietary cholesterol and serum cholesterol, consistent with the conclusions of the AHA/ACC report.^2,35.  Cholesterol is not a nutrient of concern for overconsumption.

The DGAC based its unconcern about dietary cholesterol on two references:

2.  Eckel RH, Jakicic JM, Ard JD, de Jesus JM, Houston Miller N, Hubbard VS, et al. 2013 AHA/ACC guideline on lifestyle management to reduce cardiovascular risk: a report of the American College of Cardiology/American Heart Association Task Force on Practice Guidelines. Circulation. 2014;129(25 Suppl 2):S76-99. PMID: 24222015. Its conclusion:

There is insufficient evidence to determine whether lowering dietary cholesterol reduces LDL–C.

35.  Shin JY, Xun P, Nakamura Y, He K. Egg consumption in relation to risk of cardiovascular disease and diabetes: a systematic review and meta-analysis. Am J Clin Nutr. 2013;98(1):146-59. PMID: 23676423. This study, which was also independently funded, concluded:

compared with those who never consume eggs, those who eat 1 egg per day or more are 42% more likely to develop type 2 diabetes. Among diabetic patients, frequent egg consumers (ie, > 1 egg/d) are 69% more likely to have CVD comorbidity…This meta-analysis suggests that egg consumption is not associated with the risk of CVD and cardiac mortality in the general population. However, egg consumption may be associated with an increased incidence of type 2 diabetes among the general population and CVD comorbidity among diabetic patients.

Were these references based largely on studies funded by the egg industry?  If so, PCRM is correct in arguing that the question of egg consumption and blood cholesterol levels merits much closer scrutiny and analysis than it is currently receiving.

What does a study funded by the egg industry look like?  Here are two one from my recent collection:

The effect of a high-egg diet on cardiovascular risk factors in people with type 2 diabetes: the Diabetes and Egg (DIABEGG) study—a 3-mo randomized controlled trial, by Nicholas R Fuller, Ian D Caterson, Amanda Sainsbury, Gareth Denyer, Mackenzie Fong, James Gerofi, Katherine Baqleh, Kathryn H Williams, Namson S Lau, and Tania P Markovic.  Am J Clin Nutr 2015; 101:705-713.

• Conclusion: High egg consumption did not have an adverse effect on the lipid profile of people with T2D [type 2 diabetes] in the context of increased MUFA [monounsaturated fatty acid] and PUFA [polyunsaturated fatty acid] consumption. This study suggests that a high-egg diet can be included safely as part of the dietary management of T2D, and it may provide greater satiety.

Dietary cholesterol and cardiovascular disease: a systematic review and meta-analysis. Berger, S., Raman, G., Vishwanathan, R., Jacques, P.F., Johnson, E.J., 2015. Am J Clin Nutr ajcn100305. doi:10.3945/ajcn.114.100305.  Am J Clin Nutr August 2015
vol. 102 no. 2 276-294

• Conclusion: Reviewed studies were heterogeneous and lacked the methodologic rigor to draw any conclusions regarding the effects of dietary cholesterol on CVD risk.  [Implication: suggestions that eggs might raise cardiovascular risk are unwarranted]
• Sponsor: Supported by USDA agreement 1950-51000-073 and the American Egg Board, Egg Nutrition Center.  The funders did not have a role in the study selection, quality assessment, data synthesis, or manuscript preparation.

Yesterday, the World Health Organization’s International Agency for Research on Cancer (IARC) issued a warning about the carcinogenic potential of processed and red meat.  This, as you might expect, caused a media flurry.  CNN News asked me for a written comment.  They titled it “The other benefit to eating less red meat.”  Here’s what I wrote:

Meat producers do not like the “eat less meat” message. Consumers do not want to give up their bacon and hamburgers — delicious and also icons of the American way of life.

But these judgments should come as no surprise to anyone. Eating less processed and red meat has been accepted dietary advice since Ancel and Margaret Keys wrote their diet book for heart disease prevention, “Eat Well and Stay Well,” in 1959. Their advice: “restrict saturated fats, the fats in beef, pork, lamb, sausages …” They aimed this advice at reducing saturated fat to prevent heart disease. Federal committees and agencies have continued issuing such heart-disease advice to the present day.

Cancer entered the picture in the 1970s, when scientists began to link red meat — beef, pork, lamb — to the risk of cancers of the colon and rectum. Even after several decades of research, they had a hard time deciding whether the culprit in meat was fat, saturated fat, protein, carcinogens induced when meat is cooked to high temperatures or some other component.

In the mid-1990s, dietary guidelines committees advised eating lean meats and limiting intake of processed meats, still because of their high fat content. By the late 1990s, cancer experts said that red meat “probably” increases the risk of colorectal cancers, and “possibly” increases the risk of cancers of the pancreas, breast, prostate and kidney. The IARC report, based on more recent evidence, makes even stronger recommendations and favors carcinogens as the causative factors.

To put this in context: For decades, the meat industry’s big public relations problem has been that vegetarians are demonstrably healthier than meat eaters. People who do not eat red meat havemuch less of a chance of developing heart disease and bowel cancers than the average American.

More recently, the 2015 Dietary Guidelines Advisory Committee (DGAC) found diets “higher in red/processed meats…” to be associated with a greater risk of colorectal cancer, and it recommended dietary patterns and low in red and/or processed meats, but higher in vegetables, fruits, legumes, whole grains, lean meats/seafood and low-fat dairy — largely, but not necessarily exclusively, plant-based.

This is good advice for anyone.

Eating less red and processed meats has two benefits: a reduced risk for certain forms of cancer,and a reduced effect on climate change.

The DGAC deemed eating less red meat to be exceptionally beneficial to the environment as well as to human health. The IARC report strengthens the health component of the recommendation. The secretaries of USDA and Health and Human Services, however, have refused to allow environmental concerns to be considered in the 2015 dietary guidelines.

I mention the dispute over environmental “sustainability” in the dietary guidelines because largely plant-based diets are appropriate for all kinds of health concerns — obesity, type 2 diabetes, coronary heart disease and now, especially, colorectal cancer — as well as environmental concerns.

By eating less red and processed meats, you promote both your own health and that of the planet.

At issue then is how much red and processed meat is compatible with good health. The IARC commission ducked that question, although it cites evidence that as little as 100 grams (a quarter pound) of red meat a day, and half that much of processed meats, increases cancer risk by 15% to 20%.

Will an occasional hamburger or piece of bacon raise your risk that much? I don’t think so. But the evidence reviewed by IARC strongly suggests that if you do eat meat, eat less when you do, don’t eat meat every day, save processed meats for rare treats and be sure to eat plenty of vegetables.

Fortunately, this advice leaves plenty of room for delicious meals — just with meat taking up much less room on the plate.
