Nutritional supplements and cancer prevention-what’s the hype and what’s the science?

May 29, 2012

Millions of American men and women are taking nutritional supplements with the attention of preventing cancer and other serious health conditions.  Does this work and is it worth the risk?

The US food and drug administration categorized as nutritional supplements under the general a brown of foods rather than drugs.  The supplements had not undergone clinical trials and a rigorous approval process and cannot be removed from the market and less they are proven to be dangerous or have false labile information.  It is of interest that FDA Manufacturing guidelines do not have to prove supplements safe or affective.

The risks

A little is good but a lot can’t be harmful.  Most American study had on and off vitamins in their normal diet.  By taking extra vitamins can cause an overdose.  In 2008 a more than 69,000 cases of toxicity 228 vitamin overdose were reported.

Another risk of using supplements is that some supplements can interact with medications in a way that will harm the patient.  If you are taking prescription medications you should inform your physician about any nutritional supplements you may be using.

Nutrients in foods

It is true: An apple at they may really keep the doctor away.  Fruits and vegetables contain important nutrients and fiber, which helps protect against colon cancer.  By eating fresh fruits and vegetables you can reduce both the risk and recurrence of breast cancer.  The American institute for cancer research estimated that one third of the cancers that occur every year in the United States could be prevented by lifestyle changes, including bleeding or whole foods.

The reason whole foods are more beneficial than and vitamin supplements is probably that whole foods contain any nutrients that worked in combination to protect against cancers.  For example, fresh salmon is superior to salmon oil supplements because although both provide fatty acids, Fresh salmon provides nutrients not found in oil, such as vitamin D and B,amino acids, calcium and selenium.

Foods known to help prevent cancer include: berries, grapes, tomatoes, mushrooms, green tea, salmon, squash, broccoli, cauliflower, cabbage, Brussels sprouts, linseed, and flaxseed.

Bottom line: For most people a diet that includes healthful foods can eliminate the needs for supplements.
