1. Zinc deficiency: The zinc intake of vegetarians is lower than that of non-vegetarians. Zinc deficiency will affect children's development, immune function and sexual desire. Because of the low bioavailability of plant zinc, vegetarians should strive to reach or exceed the recommended intake of zinc.

Suggestion: Eat more soy products, drupes or unrefined whole grains and mustard, which are also rich in zinc.

2. Vitamin B 12 deficiency: Vitamin B 12 is necessary for hematopoietic process and nervous system. Vitamin B 12 exists almost only in animal foods, and vitamin B 12 provided by spirulina, marine plants and soybean fermented foods has no activity. Long-term vegetarian diet leads to a serious shortage of vitamin B 12, and then special hallucinations appear.
