It seems we need more science based guidelines for protein in older adults. It’s still an unknown. Can more protein prevent protein wasting associations with aging? I haven’t heard about heart damage with too much. How much is too much? Clearly there is a problem with protein intake and kidney disease. I’m on your side, shoot for moderate levels. I avoid meat almost anyways. Keep up the good insights.

So we get back to the Mediterranean diet. People need to have short chain fatty acids from fruit fibers so that they can make butyrate which is important for extracting or metabolizing B vitamins and it's always about the quality of carbohydrates and the quality of proteins and fats most Americans can just give up white flour if they have the money . It's important to rotate your food sources people who are switching to a more plant-based diet need to know how to cook beans to get rid of lectins and there are plenty of grains to have other than wheat .pseudo grains like buckwheat or quinoa are good to add to the diet ,as we age we need more digestive enzymes and I don't think you can just get them from fruit and vegetables .avocado or nuts are definitely better than commercial Fried Chicken.. people get obsessed with counting calories it's more important to consider the quality and the ratio of good nutrients to potentially detrimental ones. It's a damn shame that Donald Trump doesn't want information from the NIH to get out to the General Public. You still have TV stations telling you what I call Reader's Digest Health news from the 50s. If there's a chance that you can make your food and stay away from pre-made food that's stored in plastic I'm sure you would do better

David, thank you for this article. The flip side of too much protein (from animal sources) is too little fiber (from plant sources). When planning healthy meals, I like to start with the fiber, then consider other phytonutrients, and finally add enough additional protein to meet a person's daily needs

After age 50, people generally require more protein. Most older people eat less, and don’t get enough high-quality protein, which contributes to sarcopenia and subsequent frailty. An average daily protein intake of 1.6g/kg lean body mass, spread out through the day, can help in preventing muscle loss, but strengthening exercises are also necessary.

I've linked to your article about protein in an update to my post:

I heard about a recent study - small - but something like 5 years on keto with HIGH average cholesterol, did not increase plaque in the keto group compared to the control group, with lower average cholesterol. That’s 5 years of keto with high protein and sat fat.

MiHeart study?
