The Pros and Cons of the Vegan Diet
By Kim Leach
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. 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. |
