Currently browsing posts about: Eggs

I read a report in the Washington Post discussing a study done by Neal Barnard and his colleagues associated with the Physicians Committee for Responsible Medicine, a group advocating for plant-based diets and animal welfare.

More than 85 percent of the studies in Barnard’s meta-analysis, whether funded by industry or not, showed that eggs have unfavorable effects on blood cholesterol. Industry-funded studies, Barnard found, were more likely to play down these findings.

The study, a meta-analysis, reviewed 153 studies examining the effects of eggs on blood cholesterol levels.  It found the proportion of egg studies funded by the egg industry to have increased since 2010, and the industry-sponsored results to be spun—no surprise—in favor of the benefits of eggs.

This matters because advice in the 2015-2020 Dietary Guidelines for Americans is unhelpful about eggs.

Here’s how I explained the confusion in my January 7, 2016 post:

Cholesterol: the recommendation to limit cholesterol has been dropped, but the document says, confusingly, that “this change does not suggest that dietary cholesterol is no longer important to consider when building healthy eating patterns. As recommended by the IOM, individuals should eat as little dietary cholesterol as possible while consuming a healthy eating pattern.”  Could the dropping of the limit have anything to do with egg-industry funding of research on eggs, the largest source of dietary cholesterol, and blood cholesterol?  The Physicians Committee for Responsible Medicine has just filed a lawsuit on that very point.

The lawsuit was about undue influence of the egg industry, but the judge threw the suit out of court because no legal standard exists for undue influence.  Oh.

What to do about eggs?  I vote for moderation, of course.

As readers of this blog should know by now, I’m a big fan of food safety lawyer Bill Marler, whose blog keeps me up to date on food safety matters.

He posted recently on a Salmonella outbreak caused by contact with backyard chickens.

The CDC keeps track of such things.  By its count,

A total of 279 people infected with the outbreak strains of Salmonella have been reported from 41 states.

• 40 (26%) people have been hospitalized and no deaths have been reported.
• 70 (30%) people are children younger than 5 years.

The CDC’s advice:

I was interested in Marler’s account because I knew that he had backyard chickens at his place near Seattle.

Here’s what he says about that:

We have had hens in our backyard since just after the DeCoster egg debacle in 2010.  I clean the chicken house about twice a month and the shoes and clothes I wear are removed before going inside.  I wear a mask and gloves when I clean and either wash my hands well or take a shower.  I do not pick up the chickens unless they are ill, and I wash my hands after I do.  I wash the eggs and refrigerate then.  They tend to get used within the week.

I do my best to think about the possibility of cross-contamination with Salmonella and/or Campylobacter.  So far, so good.

Good advice.

Here’s another in my series of post-Unsavory Truth examples of studies whose funder can be predicted by their titles.

The consumption of 12 Eggs per week for 1 year does not alter fasting serum markers of cardiovascular disease in older adults with early macular degeneration Hassan Aljohia , Mindy Dopler-Nelson , Manuel Cifuentes , Thomas A. Wilson.  Journal of Nutrition & Intermediary Metabolism 2019;15:35-41.

Hypothesis: Egg consumption is associated with reduced risk of macular degeneration, but because eggs are so high in cholesterol, they might increase the risk for cardiovascular disease.

Conclusion: “This study suggests that the consumption of 12 eggs per week for 1 year does not significantly alter fasting serum lipids, lipoprotein cholesterol, or other biomarkers of CVD in older adults diagnosed with early macular degeneration” [the hypothesis is shown to be false].

Funding: “The authors would also like to thank the American Egg Board, Egg Nutrition Center, Washington, DC (T.A.W.) and the Massachusetts Lions Eye Research Fund Inc., New Bedford, MA (T.A.W.) for their funding support. The funding played no role in data collection, analyses, or interpretation.”

Comment: So the authors say, but industry influence is often unrecognized.    Independently funded studies sometimes come to quite different conclusions, as one in JAMA did last week.  Its conclusion: “Among US adults, higher consumption of dietary cholesterol or eggs was significantly associated with higher risk of incident CVD and all-cause mortality in a dose-response manner.”

You have to have some sympathy for egg producers.  Egg consumption has been declining for years.

Egg producers blame the decline on cholesterol concerns; eggs are by far the largest dietary source of cholesterol.

Now Pete and Gerry’s Organic Eggs is petitioning the FDA to forget about cholesterol and update its definition of “healthy” so the company can advertise its eggs as “healthy.”

FDA Commissioner Scott Gottlieb said in a speech last month that the FDA would be updating the definition.

I, of course, think “healthy” is a slippery slope best avoided, and that Congress never should have allowed health claims on foods in the first place.,

But too late for that.

I don’t envy the FDA’s challenge here.  The petition is based on the dietary guidelines, but what the guidelines say about dietary cholesterol, and therefore eggs, is extremely confusing.

As I explained in a previous post, the guidelines no longer recommend a cap on dietary cholesterol of 300 mg/day (the equivalent of 1.5 eggs), but do say that people should eat as little cholesterol as possible.

Good luck on this one.

I’m trying to get my head around 200 million eggs being recalled because of Salmonella.

The Washington Post has the story:

An investigation by the federal agency led to an inspection of the farm, [Rose Acre Farms of Seymour, Ind.] which is located in Hyde County, N.C., and produces 2.3 million eggs a day from 3 million hens. Eggs produced at the farm are distributed to retail stores and restaurants in Colorado, Florida, New Jersey, Pennsylvania, Virginia, West Virginia and the Carolinas.

The recalled eggs were sold under brand names such as Great Value, Country Daybreak and Crystal Farms. They were also sold to Waffle House restaurants and Food Lion stores. (Click here for a full list of brands and stores.)

 Rose Acre Farms produces 2.3 million eggs a day from 3 million hens?

Bill Marler has the technical details: 22 people ill, and 206,749,248 eggs recalled.  I like his image:

In my book “Safe Food: The Politics of Food Safety,” I explain how Salmonella gets into eggs and how it got into them in the first place.  This was a preventable problem.  It still is, if egg producers paid close attention to following standard egg safety procedures.

These, of course, are more difficult if you are dealing with millions of eggs every day.

But that doesn’t help the people who became ill.

• The FDA announcement of the voluntary recall
• USA Today’s  Egg recall: What you need to know about salmonella
• The FDA’s report on what it found at the site (sigh)

Competition in the food service industry must be fierce these days.

My colleagues who are members of the Academy of Nutrition and Dietetics recently received this letter from a public relations firm working for Panera.

Subject: Panera’s Quest to #RespectTheEgg

Did you know 50% of the top 10 fast casual restaurants that sell breakfast have an “egg” made of at least five ingredients, often more? That’s why Panera has officially petitioned the FDA to establish a clear definition for the term “egg,” in an effort to improve standards and transparency throughout the food industry.

In the meantime, customers can rest assured that when they order an egg at Panera, that’s exactly what they’re getting. Panera has launched a line of new breakfast sandwiches featuring 100% real, freshly cracked, cooked-to-order eggs with no additives at all.

In case this is a fit for anything you’re working on, here is a link to more materials and images, including:

• Panera’s Official Press Release
• An Infographic Comparing Competitor’s Eggs and Breakfast Sandwiches (print size and JPG for social sharing)
• Images of Panera’s Breakfast Sandwiches
• The FDA Petition
• Panera’s New & Improved Breakfast Menu

You can also find detailed nutrition info on Panera’s new breakfast sandwiches here. Please let me know if you have any questions on Panera’s quest to #RespectTheEgg!

The press release does not say what evil additives are used by Panera’s competitors.  Fortunately, Forbes has a list.  Its top prize goes to Subway, but the others don’t look much better.

Here’s the ingredient list for Subway’s Egg Omelet Patty (Regular):

Whole eggs, egg whites, water, nonfat dry milk, premium egg blend (isolated pea product, salt, citric acid, dextrose, guar gum, xanthan gum, extractive of spice, propylene glycol and not more than 2% calcium silicate and glycerin to prevent caking), soybean oil, butter alternative (liquid and hydrogenated soybean oil, salt, soy lecithin, natural and artificial flavors, beta carotene (color), TBHQ and citric acid added to protect flavor, dimethylpolysiloxane (antifoaming agent added), salt, beta-carotene (color).

Hey—eggs are the first ingredient.

Panera isn’t really asking for a standard of identity for eggs.  It’s asking not to count an egg as an egg if these kinds of things are added to it.

I can’t wait to see what the FDA does with this one or if it even tries to attempt to draw the line between the items in the non-egg “premium egg blend” and additives like salt and pepper.

McDonald’s ran a full-page ad in yesterday’s New York Times:*

“At McDonald’s we’re on a journey: What’s important to you is important to us.”

The ad says McDonald’s is taking these actions [with my comments]:

• Removed artificial preservatives from Chicken McNuggets and other items [Fine, but no big deal in my book.]
• Removed high fructose corn syrup from hamburger buns [And replaced it with what?  Sugar?  This matters? I’m guessing the price of HFCS must be close enough to the price of sugar to make this possible.]**
• Committed to only source chickens that have not been treated with antibiotics [OK.  Now we’re talking important.  For this alone,  McDonald’s deserves high praise.  My only question: by when?]*** 

The ad also summarizes the company’s additional actions, done and promised:

• Burgers are 100% beef
• Eggs are freshly cracked
• Salads feature baby spinach, kale, Tuscan red leaf lettuce, and carrots
• Buttermilk chicken uses real buttermilk
• Milk is sourced from cows not treated with rbST
• 2 billion sides of fruit were served (including 59 million clementines)
• Espresso beans are Rainforest Alliance Certified
• Eggs will be cage-free by 2025

Amazing, no?

It’s worth a field trip to see how all this works in practice.  I’m on it.

Thank you readers!  Much appreciated.

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.
