Many studies link vegetarian and vegan diets to deficiencies in key nutrients including vitamin D, magnesium, B vitamins, and iodine - all nutrients that, if lacking, can lead to hormonal, thyroid, and methylation impairments.

As you read along, you'll find out that most health conditions developed by vegans are related to vitamin B12 deficiency. Without the familiar sources of vitamin B12, certain bodily functions can be disrupted, leading to anemia, gastritis, stroke, Crohn's disease, and Celiac disease.

Unfortunately, due to the highly restrictive nature of the diet, vegans are at risk of being deficient in certain nutrients such as calcium and vitamin B12 usually found in dairy and meat respectively.

Avoid vegan foods that are processed and have high amounts of sodium and saturated fats like faux meats, cheese, frozen vegan meals that come with heavy sauces, and some canned vegetables and vegetable broths that are very high in sodium.
