The American Heart Association was the first group in the world to proclaim saturated fat is bad for health (in 1961). So of course it's are not backing down. Even reject full-fat milk and normal cheese--due to sat fat content--ignoring the last 15 years of science to the contrary. An illustration in the intransigence of bureaucracies

The American Heart Association recommends getting protein from plants—rather than meat—and avoiding full-fat dairy. on.wsj.com/4m0X3h6

So true. When we published the first higher protein low carb diets in 2003 we went through 2 years of bias reviewers at AJCN. Finally published in Journal of Nutrition

The Dietary Guidelines are finally aligned with the science. Prioritize protein & balance Carbs and fats for muscle health. @DrGabrielleLyon has been a leader in muscle-centric health &her new book The Forever Strong Playbook is the essential roadmap https://.drgabriellelyon.com

Interesting question. Protein quality reflects the content & digestibility of 9 EAAs from foods under defined conditions. Glycemic Index reflects potential of different foods to impact blood glucose. PQ precedes GI by about 100 yrs
Douglas Kalman PhD@dougkalmanphdrd

@donlayman Well done Don (and the group you are working with). Can we consider this the #Protein version of glycemicindex.com ?

The protein quality Hub also features our EAA-9 calculator for determining % of RDA for each EAA in a food, meal or diet. The paper provides website & examples. Try it out. Have fun

Our new paper (bit.ly/4pVpE80) introduces our open access website for protein quality. We have captured all public available protein quality data. Hub allows for calculations for over 7000 foods & ingredients

@calleymeans “Proteinification” of junk food does not make it healthy. Deception is not the route to a healthy diet

A lot of junk food companies are advertising new protein branded snacks - still with a bunch of sugar and chemicals. To be clear - the Dietary Guidelines recommend high quality REAL FOOD protein and to AVOID highly processed food.

Control of pre-diabetes and T2D is more about reducing Carbs but you need to replace the calories. IMO increasing protein has many advantages over increasing fat. So higher Prot & reduced Carbs proven effective

So true. In India there might be 4 or 5 people eating too much protein but there is 1 billion who aren’t eating enough
Mind Muscle Project@mindmusclepro

@donlayman Thanks Dr layman, India is protein deficient in a big way, the wrong kind of messaging like that post will push people into more health crisis

😉 research should always be about providing information to help you decide what works best for you. No preaching just information
RobAround@AroundRob

@donlayman Dearest Professor: You are in my head at every first meal, telling me to get that thirty-forty grams high quality protein. Late sixties, female—your sharing your findings has made all the difference and I thank you from the bottom of my heart!

Protein only triggers phase I insulin release to support protein synthesis, glucose triggers phase II for glucose disposal. Prot replacing Carbs gram for gram reduces insulin release by 75%. Carb intake determines the outcome not protein
Aravind@aravind

Protein triggers insulin. Who will tell this to the protein propaganda bros in India promoting over-consumption of protein to an Indian population genetically pre-disposed for insulin resistance, and also causing a unnecessary demand spiking protein prices (like eggs and milk) risking the public health of already protein deficient poor people among us? Eat unnecessary amount of proteins now and, as an Indian, you may end up with diabetes later. So always better to moderate consumption of all nutrition - cut on refined, processed carbs, take only required lean protein for your health needs, increase fiber, vitamins, and minerals by eating more vegetables. And most importantly, don't fall for health fads from foreign lands parroted by colonized minds telling you "our food is bad, our ghee is bad, our coconut oil is bad, our breakfast is bad so follow this new fad" etc just like that. Think for yourself before going for any fad.

Elizabeth, thank you. That material was not part of DGA and frankly is a huge mistake by a staff person. We published the correct information in JAND (bit.ly/45HXoyp) and in the actual DGA report, Appendix page 362, Tables 1 & 2. We are working with HHS staff to get this corrected. Thanks
Elizabeth Ward@EWardRD

@donlayman I understand your point about the protein ounce equivalents when it comes to plant foods, but they are saying that 1 egg has as much protein as 3 ounces of meat, chicken or seafood. That is incorrect.

True. Chicken. the 2010 DGA reported the increase in breaded & fried chicken products, wings, chicken sandwiches and nuggets and accounted for the second leading cause of increased calories in US diet after pastries and bread. Are those nutritionally equal?
Tamar Haspel@TamarHaspel

@donlayman In that time, us meat consumption per capita has risen from about 100 kg per yr to about 120, so it's hard to make the case we've turned away from animal foods and that's responsible for obesity and attendant diseases.

Honestly I have not seen all of the serving size statements but we recommended significant correction of previous Protein Ounce Equivalent that were grossly in error for both protein and essential amino acids
Ken Echevarria, MS, RDN@ken_echevarria

@donlayman It’s a tiny thing- but do you know why they chose to change the serving size of meat/poultry/seafood from 1 to 3 oz, legumes from 1/4 cup to 1/2, and keep egg as 1 egg? Were they controlling for total protein, quality of protein, protein:calorie ratio, or total calories?

I ran 3 large clinical trials (I’ll post ref. later) that demonstrated you could target 1.6 g/kg protein with 65% protein from animal foods and still meet fat guidelines of <30% of total kcal and <10% SFA. The argument that the DGA are “inconsistent” does not recognize the intended shift in perspective. You are allowed to get your SFA from natural, nutrient-dense animal protein foods and you can still meet current SFA guidelines. All that said, do I personally think the 10% SFA is a legitimate government guideline for everyone … no, but until the science can elucidate the real risk, I’m willing to work with the number. However, should that number be used to demonize specific foods or to create healthy diets?

The new Guidelines eliminate to goal to demonize animal source protein foods (ASF). There is no question protein quality and nutrient density are better in ASF, but they also have SFA. An egg is a nutrient rich food, but it can never be considered an excellent or even a good source of B12 (1 large egg = 25% RDA) because it has 19% SFA, even though it only has 1.6 g of SFA. If you think of the SFA guideline as a diet goal (versus a food critique), a 2000 kcal diet with 10% SFA = 22.2 g SFA. One egg is irrelevant. So, if you choose to use ASF in your diet, the ASF will be the source of your SFA. Currently Americans get nearly 35% of SFA from hydrogenate seed oils. Is that better than the SFA in an egg or dairy?

I’ve listened to a lot of critiques about the DGA. The biggest controversy seems to focus on saturated fat (SFA) … as expected. Let me share a different perspective. For 50 years, saturated fat and cholesterol have been used to demonize animal-derived foods even though both are essential in the human body. From 1975 until 2010 there was a 35% decrease in consumption of eggs, dairy and beef and a decrease in SFA from 15% to 11%. Benefits? None, but it did result in massive increase in processed foods and epidemics of obesity and diabetes.
