Recently, vegetarian diets have experienced an increase in popularity. A vegetarian diet is associated with many health benefits because of its higher content of fiber, folic acid, vitamins C and E, potassium, magnesium, and many phytochemicals and a fat content that is more unsaturated. Compared with other vegetarian diets, vegan diets tend to contain less saturated fat and cholesterol and more dietary fiber. Vegans tend to be thinner, have lower serum cholesterol, and lower blood pressure, reducing their risk of heart disease. However, eliminating all animal products from the diet increases the risk of certain nutritional deficiencies. Micronutrients of special concern for the vegan include vitamins B and D, calcium, and long-chain n-3 omega-3 fatty acids. Unless vegans regularly consume foods that are fortified with these nutrients, appropriate supplements should be consumed. In some cases, iron and zinc status of vegans may also be of concern because of the limited bioavailability of these minerals. A nationwide poll conducted in April by Harris Interactive reported that 1.

The vegan group also managed to reduce their medication significantly more than those who belonged to the other group, a significant finding in light of the fact that some hypoglycaemic drugs contribute to weight gain Barnard et al. If you follow or are interested in a vegan or vegetarian lifestyle, you may need to put in more effort initially to learn where your nutrients are coming from. Vegans are consistently reported to have lower intakes of calcium and vitamin D, with resultant lower blood levels of vitamin D and lower bone mineral density reported worldwide. Conclusion After a brief introduction, I argued in the second part of this appendix that vegan diets can be nutritionally adequate, but that vegans must make sure to consume foods that contain adequate amounts of vitamin B12 and omega-3 fatty acids as the former cannot be obtained from plants and the latter are present in significant quantities only in a few common vegan foods.
Hidden hunger affects over two billion people, globally. The cause is a chronic lack of essential micronutrients in the diet, such as vitamins and minerals. The effects of these nutritional deficiencies may not be seen immediately, but the consequences can be severe. They include lower resistance to disease, mental impairment and even death. While many of the cases of hidden hunger are found in developing countries, this phenomenon is also a growing public health concern in developed countries. For example, iodine deficiency is the most common cause of preventable mental impairment and the UK ranks seventh among the ten most iodine-deficient nations. And data from the US shows that more than one in four children lacks calcium, magnesium or vitamin A, and more than one in two children are deficient in vitamin D and E. There are several causes of hidden hunger in developed countries.
