Veganism is malnutrtion.

Plants don't have:
Vitamins: A, B6 (pyridoxal. pyridoxamine), B12, D, F, K2
Amino acids: Creatine, Carnitine, Carnosine, Taurine
Heme-iron, CoQ10, CLA

Here are some basics on vegetarians:

Here are their problems as to why they usually quit:

Vegans are deficit in b12:

High fiber diets reduce serum half life of vitamin D3:

Vegans are deficient in Coenzyme Q10:

https://www.ncbi.nlm.nih.gov/pubmed/16873950

Vegans are deficient in iron due to the fact that iron from plant sources is less bioavailable than iron from meat sources:

Veganism causes loss of libido and erectile dysfunction:

Children who are raised on strict vegan diets do not grow normally:

https://www.ncbi.nlm.nih.gov/pubmed/4067152
https://www.ncbi.nlm.nih.gov/pubmed/8005079

Children develop rickets after prolonged periods of strict vegetarian diets:

"There are some links between vegetarians and lower birthweight and earlier labour"

Effects of vitamin B12 and folate deficiency on brain development in children:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3137939/

"Particular attention should be paid to adequate protein intake and sources of essential fatty acids, iron, zinc, calcium, and vitamins B12 and D. Supplementation may be required in cases of strict vegetarian diets with no intake of any animal products."

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2912628/

These next five are case studies:

Nutritional vitamin B12 deficiency in a breast-fed infant of a vegan-diet mother:

https://www.ncbi.nlm.nih.gov/pubmed/3948463

"We report the case of a 7 month-old girl that presented with acute anemia, generalized muscular hypotonia and failure to thrive. Laboratory evaluation revealed cobalamin deficiency, due to a vegan diet of the mother."

https://www.ncbi.nlm.nih.gov/pubmed/18293883

Most recent studies using more sensitive techniques for detecting B12 deficiency have found that 68% of vegetarians and 83% of vegans are B12 deficient, compared to just 5% of omnivores. https://www.ncbi.nlm.nih.gov/pubmed/12816782
https://www.ncbi.nlm.nih.gov/pubmed/10966896
https://www.ncbi.nlm.nih.gov/pubmed/10552882

On paper, calcium intake is similar in vegetarians and omnivores (probably because both eat dairy products), but is much lower in vegans, who are often deficient.
https://www.ncbi.nlm.nih.gov/pubmed/21139125
http://ajcn.nutrition.org/content/70/3/543s.full

Vegetarians and omnivores have similar levels of serum iron, but levels of ferritin—the long-term storage form of iron—are lower in vegetarians than in omnivores.
https://www.ncbi.nlm.nih.gov/pubmed/24871479

Fruits and Vegetables
https://www.ncbi.nlm.nih.gov/pubmed/12064344

This is significant, because ferritin depletion is the first stage of iron deficiency. Moreover, although vegetarians often have similar iron intakes to omnivores on paper, it is more common for vegetarians (and particularly vegans) to be iron deficient. For example, this study of 75 vegan women in Germany found that 40% of them were iron deficient, despite average iron intakes that were above the recommended daily allowance.

many plant foods that contain zinc also contain phytate, which inhibits zinc absorption. Vegetarian diets tend to reduce zinc absorption by about 35% compared with omniovorous diet.
http://ajcn.nutrition.org/content/78/3/633S.long

Thus, even when the diet meets or exceeds the RDA for zinc, deficiency may still occur. One study suggested that vegetarians may require up to 50% more zinc than omnivores for this reason.
