Vitamin E C (0.04), O (0.04), V (0.04), M (0.05)
Selenium O (0.13), V (0.12), M (0.09)

  1. We here consider four different diets, control, ovo-lacto vegetarian, vegan, and methionine-restricted diets. For the definition of these diets, refer to the main text. In a given diet, each nutrient is assigned θ, and low θ indicates a risk of the nutrient deficiency in that diet (see Methods). We list the nutrients that have θ ≤ 0.15 in at least one diet. For each nutrient, we specify the diets that give θ ≤ 0.15 (C, control; O, ovo-lacto vegetarian; V, vegan; M, methionine-restricted; the specific value of θ is presented in parentheses beside each diet). Here, we omit rather trivial information, i.e., the risk of vitamin B12 deficiency in a vegan diet (see the main text) and the risk of methionine deficiency in a methionine-restricted diet.
