Vegetarian Diets with Life Style and Nutritional Problems with Nutritional Quality of Foods

Vegetarian and vegan diets are becoming more and more popular as the benefits they offer to human health and the environment become more widely recognized. However, even while eating a vegetarian diet has been linked to a lower risk of mortality and chronic diseases, adherents to these diets may not receive enough nutrients, which may limit the positive effects on their health. The nutrients iron, calcium, vitamin B12, vitamin D, iodine, and selenium are the primary ones to be concerned about. Vitamin B12 supplementation is necessary for anyone adhering to a vegetarian or vegan diet. Adults should take one oral dose of 50–100 μg cyanocobalamin daily or two oral doses of 2000 μg weekly to prevent vitamin B12 insufficiency. Supplementing with iodine is advised for vegetarians and vegans who cannot obtain sea vegetables or meals fortified with iodine, as well as for expectant and nursing mothers. For adults, 150 μg of iodine supplements should be taken daily. It is crucial to comprehend the full range of consequences associated with a vegetarian diet, not just the nutritional ones. Studies in this field may help mitigate all variables that could discourage people from adopting a vegetarian diet or negatively affect the quality of life of those who already do so, in addition to providing more consistent data.
