What are protein sources for vegans?

Seeds, grains, nuts and pulses, and there's also a smaller amount of protein in most other plants.

Herbivores get their protein from the same site. Cows don't eat meat, despite the fact that they need a lot of protein to develop. And the protein that meat eaters get from cow meat isn't obtained from the cow meat itself. It's derived from the plants that cows drink.

Meat is a great way to get a concentrated dose of protein with little effort, but one can get all the protein one needs without consuming meat.

chick peas, quinoa, tofu, buckwheat, chia seeds, cereals, rice and beans, seeds, peanut butter. Those are some options but being vegan isn't necessarily healthy even though you think it might be "helping the environment." 

Vegan diets lack nutrients in these particular:

Vitamin B12

Calcium

Iron

Zinc

Iodine

Essential fatty acids (long chain) EPA and DHA (essential for brain health)

Proteins, essential for neurotransmitters (brain function) and healthy tissues

Fat soluble vitamins A and D, very important for brain and hormonal health

(Also taking a bunch of supplements to try and "replace" those things isn't really good. Taking loads of supplements isn't healthy at all.)

Vegans may also replace the calories from protein sources with refined carbohydrates including bread, crackers, and cookies. Over-consuming carbohydrates can lead to non-alcoholic fatty liver disease, blood sugar dysregulation, and other troublesome symptoms.

plus yam and casava.

Almost all vegetables and grains have protein in them! Green peas, quinoa, rice and beans together, nuts and nut butters, leafy greens.. Personally, I recommend staying away from protein powders - they are expensive, and there is, for me at least, some doubt as to our need for so much protein! 

Mother's milk has about 6% protein, and it is the perfect food for a baby. In other cultures, some babies are breast fed until age 4 or longer.. and these babies thrive on 6% protein.. you might be thinking, 'well, that is because they are small and don't do much', but the truth is, at no other time in our lives do we grow as much as when we are babies! A baby doubles in size in 2 years.. they are building bone, cartilage etc.. all on 6% of their diet being protein.. a typical protein powder could have as much as 30 - 60 grams of protein in a single drink.. and some claim that it is hard on the kidneys.. 

Back to the 6% protein - cows, oxen, horses are huge, strong animals who eat hay.. the protein in hay varies quite a bit, with some types having only about 6% protein.. and although we aren't animals, I personally think that this goes to show that tons of protein is not needed to make you big and strong
