Vitamin B12, Diabetes, and “Superagers”
In a National Institutes of Health study, vegan and vegetarian participants tended to score higher than meat eaters on a depression-measuring scale. While the results don’t prove causality, it wouldn’t be surprising if nutritional shortfalls were to blame, the researchers said. In particular, vegetarians and vegans are often low in vitamin B12, and animal products are the only natural source of this nutrient. However, it’s possible to reach the recommended levels by taking supplements or by eating fortified foods such as soy milk and breakfast cereal.
