Step-by-step explanation:
People who are vegetarian are at risk for vitamin B12 deficiencies. Vitamin B12 is found primarily in animal products such as meats, dairy, and eggs. Since vegetarians avoid these sources, they may not get enough vitamin B12 in their diet.
Additionally, vegetarians may also be at risk for protein deficiencies. While it is possible to get enough protein from plant-based sources, it requires careful planning and a variety of sources to ensure all essential amino acids are obtained.
Vegetarians are generally not at risk for vitamin C or carbohydrate deficiencies, as these nutrients can be obtained from a variety of plant foods.
