“High-quality” is an extremely vague notion I'm glad you said that. This notion of "high quality" just refers to the essential amino acids it contains. There is no intrinsic quality to a particular protein source, they are broken down into single amino acids or very small (tripeptide or less) in digestion, anyway. Anyone can get all essential amino acids necessary for their body's protein synthesis from a mix of plant sources, too, it just requires a little planning. Most people should look more at metabolic disorders as a factor in middle age or later sedentary lifestyles, and maybe even secondary vascular disorders' role in health and muscle density in later life. Being active when you are young is great, but their are many other factors in later life health. There is good evidence that veganism is associated with improved average longevity (among other good outcomes). I don't care who eats meat - I do - but it's better to do it with eyes open, and not for faulty reasons. Bringing it back to the article though, some of the plant based products being brought to market give me pause because of how processed they are. The salt, sugar, and fat levels are getting high and you lose the benefits of less processed vegetables.
