Children who want to adhere to vegetarianism, it is advisable to get the necessary nutrients with products, meat and fish substitutes. Examples are soy products, including soy milk and nuts. They are sources of protein, but also of iron, zinc, calcium and vitamin D, which children are deprived of, avoiding meat. Yeast is rich in vitamin B12, and linolenic acid can be obtained from flaxseed.

Vegetarianism can be started as a child, according to some nutritionists at All Children's Hospital in St. Petersburg. If the young have eggs and dairy products in their diet, they will not be deprived of essential substances for their growth and development. However, vegans need to become a little more sensible, pediatricians warn.
