New study, Eating animal protiens is good for the heart!!

Postby veggiesusie » Sun Aug 30, 2015 8:00 pm

A friend of mine pointed out this new . Although it says plant proteins are important , it seems to stress the importance of animal proteins as heart healthy.
I can recall reading from plant based doctors that a vegan diet increases the flexibility of the arteries, not the other way around like this study is saying.

Could readers please comment. thanks

Very reductionist study and we don't consume "amino acids" we consume whole foods. This study confuses the real outcome that plant foods are helpful to the endothelial cells and lower blood pressure (lower central blood pressure is a definite finding in this study itself). Since animal foods contain fats and cholesterol, there's no way that they are beneficial to the heart. This study is really nonsense. For a good summary of how to spot a reductionist study, I would suggest picking up the book "Whole" by T. Colin Campbell which is very informative.

All the foods in the Starch Solution have protein. The only foods low in protein are fruits.

Dr. McD is still right: "People love to hear good news about their bad habits" :\

http://jn.nutrition.org/content/early/2 ... 0.abstract

Here is an abstract of the original article. It is in an open access journal. Does this mean it was not subject to peer review?

The subjects filled out food recall questionnaires.

Among the amino acids methionine is conspicuously missing. How did they compile their lists without this amino acid which is present to a much greater extent in animal protein than plant protein? And which has been identified, at least by some plant based advocates, as the main trouble maker in some illnesses. How can you eat amino acids from animal food without consuming methionine?

It is unlikely that there were very many wfpb no fat eaters among the twins. It did not look like they asked one of each set of twins to consume a plant based diet. Perhaps the full article would answer this question. Compared to the amount of meat most people eat, the amount eaten in the study did not seem like very much, with as little as about two or three ounces which may or may not have been the amount per day.

There does not appear to be any conflict of interest or direct funding from agribusiness.

If you based your diet on the above study, you could justify a paleo diet. Lots of meat and vegetables.

This journal has an editorial board composed of experts in the field of nutrition from various prominent universities. They are only looking at the helpful amino acids and selecting out the detrimental amino acids. It's not each individual amino acid that matters, but the whole package! Plus, foods never have nutrients in isolation. When you look at fiber intake, it blows everything out of the water, because fiber is only in plant foods. No one should base anything on this study, especially what one eats! No one should cite this study to justify anything either! It's pretty useless and should be in the circular file. They're not even looking at the end outcomes of heart attack, stroke, not even clinically relevant lab markers, but these "indicators" of arterial function such as the PWV, etc. The only use of this article hypothetically may be a manufacturer who is looking at what to put in a "protein" supplement.

Thanks for the book recommendation. I bought it and started reading.

Open access and peer review are separate issues. The Journal of Nutrition is peer-reviewed. They apparently have an option for the authors to make their accepted article immediately freely available online to anyone by paying $3000. Otherwise the article will be available to subscribers only for 12 months and freely available online thereafter. They do require the authors to transfer the copyright to the journal (some of the more open open-access journals don't), but automatically grant relatively extensive rights back to the authors (the right to reproduce the article in compilations such as theses etc.).

It didn't take long, but TN Beef Council already is citing this study on their twitter account saying
Eating #steak daily could be as good for heart as quitting smoking
and links to this article: http://www.dailymail.co.uk/health/article-3212807/Eating-steak-salmon-day-good-heart-giving-smoking.html

More unbelievable is their facebook feed, where they are suggesting to make pureed beef as baby's first food after breastmilk ?!?!?! WTF!

Wonderful!
We could probably start a whole thread on this discussion board for discussion of this book!

I just noticed that in the first page of the picture book, in the list of starches, beans are listed first. Maybe this means the Starch Solution has become more conscious about protein.
