Why are vegans at risk for vitamin B12 deficiency?
Abstract. Since vegetarians have a lower intake of vitamin B12 (B12) than non-vegetarians, they are at increased risk of developing B12 deficiency. The less animal products the food contains the worse the B12 status. However, even lacto-ovo-vegetarians run the risk of becoming deficient in B12.

Where do non-vegans get their amino acids?
The same way non-vegans ultimately get them—from plants. The “essential” amino acids are amino acids that humans can’t synthesize within their own bodies. But here’s the fun part: to the best of my knowledge, no other animal can synthesize them, either. They have to come from plants. So even though a non-vegan will typically get most of theirs from eating meat, the animal (s) that the meat came from probably got them from plants.
What is the best protein for vegans?
Soybeans and soy products are among the only complete vegan proteins. However, these foods are not great sources of the essential amino acid methionine. To ensure that you meet the recommended dietary allowance of approximately 1,400 milligrams for a 160-pound person, you should include grains and other legumes in your daily diet. Starting off your day with 1 cup of oatmeal provides you with 335 milligrams of methionine. Drinking 1 cup of soy milk with this adds another 213 milligrams. At lunch, you can mix a 1/3-cup serving of dry-roasted peanuts with 1/4 cup of sunflower seeds to add another 543 milligrams. Finishing your day with 1 cup of whole-wheat spaghetti and 1 cup of cooked broccoli adds 363 milligrams, bringing your total to 1,454 milligrams of methionine.

Eating a sandwich containing two slices of whole-wheat bread and 2 tablespoons of peanut butter adds 476 milligrams, while a late-afternoon snack containing 1/4 cup of pistachios and 1/4 cup of cashews adds 647 milligrams. Topping 1 cup of quinoa with 1/2 cup of cooked lentils and 1 cup of cooked broccoli at supper provides another 1,300 milligrams, resulting in a total of 2,739 milligrams.

For vegans, who do not consume animal foods, plant-based proteins must provide complete forms of protein. The belief that vegans can't get all the essential amino acids is a myth; it is possible to consume enough protein to supply the vegan with the essential acids required by the body. A vegan with a well-rounded diet does not lack amino acids. Soybeans, quinoa and buckwheat are sources of complete proteins and suitable for vegan diets.
How many amino acids are produced in the human body?

What Are Amino Acids?
The food you eat is made up of an array of nitrogen-containing organic compounds called amino acids. Amino acids are often described as the building blocks of life because they bond together to create long chains called proteins. Amino acids make up 75 percent of your dry body weight. All of your hormones, neurotransmitters and signaling molecules that influence the activity of your brain and body are made from amino acids.
