The decision to change over to a vegan lifestyle happens for many reasons. Whether it be for moral, ethical or health reasons, this decision should be thought out carefully, for there are benefits and risks that go along with the vegan diet and lifestyle. Studies have shown that while many people tout that the vegan diet is more healthy than those who eat a mixture of both animal and plant products, the truth is that the vegan diet has its own issues that can be a deterrent to healthy living.
While eating fresh fruits and vegetables are considered to be heart healthy and reduce chances of high cholesterol, obesity and blood sugar levels, there are some nutrients that are not supplied by the vegan diet and should be seriously considered if a vegan diet is being contemplated by an adult.
Vitamin B12 is a nutritional necessity that is not provided by any plant product. It is only found in animals or animal by products. Therefore this should be known before starting to go on a strict vegan diet. While it is true that the liver has stored Vitamin B12 in itself and may not be depleted for some time in an adult, the same cannot be said for children. If children are to be on a vegan diet, they need to have B12 supplements in order to keep them from becoming deficient and having some severe health issues such as pernicious anemia.
Iron is another nutrient that is not found in large quantities in the vegan diet. Therefore, for the person who is either on a vegan diet, or thinking about starting one, Iron supplements should be considered as well. There are good plant beased meat products that are rich in iron and you can buy plant based meat online very easy. Other health issues such as people who are prone to urinary problems or have a family history of either ovarian or testicular cancer, usually have high levels of potassium or zinc in their blood should not be on a vegan diet at all.
People with problems such as kidney failure and have high levels of protein, phosphorus, and sodium while low in potassium and zinc are good candidates for a vegan or vegetarian diet. Individuals should be evaluated by a licensed medical professional and blood levels drawn to see if their liver and kidney functions warrant such a change in diet before anyone decides to take on this type of lifestyle.
