Red meat and heart disease link: Not all about the fat?

Answered on August 19, 2014
Created April 16, 2013 at 2:41 AM

A new study has come out saying its the amino acid Carnitine, commonly found in red meat, which leads to CHD via an altered gut biome which alters the way your body handles cholesterol supposedly. Any thoughts on this subject? The article is here, and they link to the study (free) http://www.latimes.com/health/boostershots/la-heb-carnitine-heart-disease-microbiome-20130408,0,6081972.story . If this has been asked before I'll close my question, but it's definitely new and different than the previous research regarding the health benefits/costs of red meat in that instead of focussing on fat it's the amino acids (which I find particularly interesting) and gut biome they're focussing on. Thoughts? Critiques? Explanations?

Thanks for the article. I don't know the answer though.

I am not concerned about at all because carnitine is found in red meat, not chicken breasts, salmon, eggs/egg whites, whey protein, or whitefish. Also, yeah I eat plenty of fiber from green vegetables...fitness models do the same. I don't think there's anything to worry about unless you eat a low fiber diet, eat an excessive amount of red meat, and/or take carnitine supplements (which I've done in the past but will likely not do again in the future).

Hey Stephen, there was some good discussion on this thread. Don't close if your link gets access to the full study, but it was behind a pay wall when I tried. http://paleohacks.com/questions/190129/new-nyt-article-on-red-meat#axzz2QakmmcFb

That's an interesting take, I was thinking something similar in that certain vegetables might provide some sort of a protective effect over meat consumption. How do you personally reconcile this with the macros including 40% protein that many fitness models seem to have? Is it as simple as, they eat a lot of fiber in your eyes?

The Jaminet's give a pretty good explanation http://perfecthealthdiet.com/2013/04/lessons-from-the-latest-red-meat-scare/

There are quite a few questions on this study already.

I think one of the most powerful critiques for this study is that the sample size is SIX people. The "control group", vegetarians whose gut flora is not altered by heavy meat eating group, consists of only ONE person. There is no statistical significance that can come from this.

While it may be worth investigating, I think it's their duty to further experiment before they write the study, not ours.
