"It is the position of the American Dietetic Association that appropriately planned vegetarian diets, including total vegetarian or vegan diets, are healthful, nutritionally adequate, and may provide health benefits in the prevention and treatment of certain diseases. Well-planned vegetarian diets are appropriate for individuals during all stages of the life cycle, including pregnancy, lactation, infancy, childhood, and adolescence, and for athletes." - American Dietetic Association
"A vegetarian or vegan diet can be suitable for everyone, regardless of their age." - NHS UK
"[I]t is possible to follow a well-planned, plant-based, vegan friendly diet that supports healthy living in people of all ages, and during pregnancy and breastfeeding." - British Dietetic Association.
"For adults, protein from two or more plant groups daily is like to be adequate. " - World Health Organisation

This is definitely false. Newborns not given mother's milk are worse off than those that receive maternal milk. Newborns given milk that is non-dairy substitutes not incorporating dairy are unlikely to living a long time. People in predominantly vegetarian countries like India and those that eat far less animal protein live significantly shorter lives than those in countries that eat more meat.
Consuming a diet low in meat, eggs and dairy products may extend one’s life, according to two new studies. While one study was conducted in mice and the other on people, both reached the same conclusion. And both appear in the same March 4 issue of Cell Metabolism
You don't have to eat a lot, but you have to eat some. India is a major counterexapmle to your thesis, it has one of the lowest consumptions of animal protein and yet low life expectancy. Breast milk is animal protein, or you'd have to include dairy too. You can justify it for animal cruelty reasons, but not for health reasons.
> India ... has one of the lowest consumptions of animal protein and yet low life expectancy
False cause fallacy.
> You don't have to eat a lot, but you have to eat some
Because you say so? Or do you have a source for your claims?
> Breast milk is animal protein, or you'd have to include dairy too
Vegans have a saying: "not your mother, not your milk".
It's one fallacy after another. You really should read the article I've linked, it's all there. Read it. At least skim it. It's not that hard.
> You can justify it for animal cruelty reasons, but not for health reasons
You think that adult humans have to drink cow milk to be healthy, do I understand you correctly? Not dog milk, not lion, giraffe, rat, pig milk, but cow milk specifically?
