What should i be careful of when vegan?

Since vegetarians don't eat meat, they run the risk of losing protein and vitamin B12. Vegans, who do not consume any animal products, follow an even more restrictive diet. Without eggs or dairy products in their diet, vegans should monitor their intake of calcium and vitamin D, as well as protein and vitamin B. If you are not careful, following a vegan diet may cause you to develop some deficiencies in vitamin D, calcium, omega-3 fatty acids and zinc. Since this diet does not include meat, a popular protein source for many, those who follow a vegan diet should be careful to consume plenty of high-quality, vegan-friendly proteins.
