Low 25-hydroxyvitamin D concentrations in the serum have been documented in vegan societies, especially in winter or spring, or in those living in high latitudes [6,43,56].
Deficiencies in minerals such as iodine, calcium, and zinc may also occur. Iodine deficiency is very common among vegans, often leading to acquired hypothyroidism [58].
In vegans, low plasma zinc levels can lead to iron deficiency anemia. Zinc-rich plant foods are wholemeal bread, peas, corn, nuts, carrots, whole grains, wheat germs, soybeans, cabbage, radish, watercress, and legumes [4,30,62].
