Beta carotene is found most commonly in yellow and orange vegetables, like
squash and sweet potatoes. This mineral was previously believed to reduce the
risk of cancer, this may still be true; however, many fruits and vegetables
with beta carotene also contain lycopene and lutein, which may be what actually
lowers the risk.
Beta carotene is also an antioxidant, and helps the immune system to target
and destroy cancer cells in the body. This mineral has also be closely linked
to Vitamin A, and is the precursor for the vitamin. And, since Vitamin A has
been known to cause lung and respiratory problems when taken in excess, beta
carotene has been reported to increase the risk of lung cancer in individuals
with asbestos and those who smoke. However, the daily allowance of beta
carotene found in multi-vitamins is generally considered safe.
Calcium
Calcium, along with Vitamin C and iron, could cause diarrhea and abdominal
pain. Calcium, which is usually taken in conjunction with Vitamin C (lots of
orange juice now have added calcium), has been known to increase collagen
production and help in developing strong bones and teeth despite these claims.
Taking more than 500 mg of Vitamin C per day could cause damage to the
immune system, decreasing the body’s ability to fight off outside toxins.
However, Vitamin C has also been known to help cure colds, prevent cancer, and
fight off cardiovascular disease. Iron can help in the avoidance of anemia, or
low blood count and can increase energy, but can also cause extreme
constipation if taken every day.
It’s best to get the right amount of iron from green leafy vegetables, like
spinach and cabbage, and to consume at least three fruits containing Vitamin C
per day. Calcium can be found in foods like milk, yogurt, or rice, so try to
include these into your diet so that you won’t have to rely on supplements
completely.
Whether or not you buy into medical reports that vitamin supplements are
completely harmful, it’s important to rely on vitamins to be just
that—supplements. Adding vitamins to part of a healthy diet can help you
receive maximum benefits and reduce health risks.
