Mind you there are plenty of top athletes, especially among tri-athletes, who are vegetarian, who are medallists, who do not suffer "fatigue" and who don't 'always' combine 'as taught' the perfect amino acids.
The evolutionary point here is that for several millions of years humans thrived pretty well, without "fixing" the amino acid ratio more frequently than haphazardly. We need these combinations over the medium to long term, but not on a per meal or daily basis.
yeah, I think you needed some rice & maybe one more vegetable in there.
For protein you can eat soya, paneer(indian cottage cheese), tofu or lentils.
Dont mean to hijack the discussion, but I did notice a lot of people are curious about what consists of "vegetarian" food. To bust a myth, vegetarian does not mean just vegetables.
There are two types of food - staple and non-staple. Meat is a staple food. For vegetarians, rice or wheat consists of the staple food. The vegetables are extra.
Usually my meal consists of sizeable quantities of (dishes made of) rice or wheat, with some gravy made mainly with pulses & vegetables, and a bit of fried or boiled vegetables to go with it. There is rarely ever salad or raw vegetables or anything of the kind, on my plate. The meal is extremely tasty (and not necessarily healthy).
When I tried tasting meat (tried a few different kinds - chicken, mutton, beef), what I found is that meat doesn't even come close to the taste of vegetables. It is perhaps closer to (and better compared with) rice / wheat because it is staple food.
Though I prefer meat over vegetarian food any day, veg food can be satisfying.
How about you guys try something I'm gonna make for brunch today - Aalu ka paratha.
Its pretty simple.
Boil some potato's, peal and mash them.
Add some chopped onions, salt, pepper & other spices to taste and mix with the mashed potato's.
Now knead some dough.
Make 2 small balls of dough & roll them out. Spread your mashed potato mix over one of the rolled out pieces of dough & cover it with the other one.
Cook it in a hot pan. When one side it done, flip it over & apply oil over the side that's cooked(or you can skip this part if you're watching fat & make a aalu ki roti instead).
When the other side is done, flip the paratha & oil again. Flip again after a few seconds.
Your paratha is ready.
Eat with pickle, yogurt, chutney, salsa, ketchup or butter.
Try googling if my instructions are hard to understand.
Off topic: Where in India are you from?
You use an erroneous definition of staple. Meat is most certainly not a "staple". North Americans "staple" is potatoes. For most Asians the staple is rice and pulse, for South Americans the staple is both potatoes and rice (only because rice production is highly subsidised) but it used to be corn. In Africa, due to high subsidies to corn, it has become the staple food of poor nations.
Personally, I stay away from Staples.
