Sorry Ji,
I was referring more to a vegetarian diet compared to a meat diet.
Yes, meat will digest slower, but thats because it requires lots of blood and enzymes from your white blood cells, so it is very taxing for your body...you want more blood providing the amoni acids to yout muscles and cells rather than be pumped into your digestive system to digest the food.
So for overall heath, good skin, good cell repair, organ function, having a digestive system that is not overworked is best. and having as many raw foods helps keep your digestive system work efficiently as raw food already have the digestive enzymes in them.
Slow digesting proteins are good in that they supply a nice amount of proteins to aid muscle regeneration, but even if you get too many amino acids quickly (more than the body needs), the liver will store the amino acids (amino acid pool) and release them as and when required.
Any amount of Red meat is bad for you...results from a long-range study showed even eating it once a week severely damages your health

Nuts are a good source of many of the amino acids, and most only contain 'good fats' these fats are 'used' by the body and generally wont be 'stored' by the body. and also lower cholesterol.
ofcourse balance is key...but my original points were geared towards keeping healthy on a vegetarian diet.
god bless all.
