Where do you get your protein on a plant based diet?

Um...from the proteins in the plants you consume?

Yep, it's a myth that plants do not have protein. The myth is reinforced in various ways, but lets look (for example) at competitive professional body builders with extreme levels of musculature, who consume mostly animal protein foods. Yes, one advantage of animal based proteins is they are effective at building muscle size.

So what are the disadvantages? Many pro body builders die in their 30's 40's and 50's of heart diseases. Some of that is certainly anabolic steroid use, but all of these premature deaths also had the condition of atherosclerosis, which is the build up of fats and cholesterol on the artery walls. As we all know, this is also the plaque that narrows arteries reducing blood flow. And plaques can also burst, causing blood clots. 

Is the cause of premature death in body builders mostly anabolic steroid use? Probably not, considering the primary cause of premature death in the general population is also due to sclerotic plaques in the arteries.

Another thing that is not generally mentioned in discussions of heart disease is that plaque build up is not limited to the arteries, it also occurs simultaneously throughout the vascular system (veins, capillaries, etc), and there are various dysfunctions in health that additionally occur as a result.

Basically we do not want plaques anywhere in our cardiovascular system, and if we can reverse that condition we should. And we can reverse it...in fact, logistically, it is not all that difficult.

How common is this condition? In the developed west extremely common, it is found in the autopsies of teenagers who died accidentally. 

It is caused primarily by the western diet, which is increasingly clear, on an ongoing basis.

But it is difficult to change the diet we grew up with, we unconsciously associate the early diet with survival, even, ironically, if it is killing us. Smoking is the same, we unconsciously associate it with the early feeding mechanism of sucking in mothers milk needed for survival. Out of all the addictions, oral addictions are probably the most common.

And BTW, health producing behaviors are not addictions. Addictions, by definition, destroy health. Some will say "I'm addicted to exercise", but that is actually a misnomer, because exercise is health producing.

I'm addicted to breathing? No, that is just silly.

Speaking of exercise, just what can plant proteins produce in terms of muscle size and quality? Have a look at what these two gents have gained in terms of size and function, and more importantly, what has been gained in overall health.
