  c. Vitamins A, C, and E are generating a great deal of interest for their role as anti-oxidants that neutralize free radicals, which are believed to increase a person's risk for various cancers.
  d. The majority of vitamins are synthesized in the body in adequate amounts, but because they are not stored, daily dietary intake of these substances is necessary.

Answer to Question 1

C
Certain vitamins (A, C, and E) are currently of considerable interest in their role as antioxidants that neutralize substances called free radicals, which are thought to produce oxidative damage to body cells and tissues. It is believed that oxidative damage increases a person's risk for various cancers.
Fat-soluble vitamins (A, D, E, K) can be stored in the body. Hypervitaminosis of fat-soluble vitamins can result from intentional or unintentional megadoses of supplemental vitamins, ex-cessive amounts fortified foods, and a large intake of fish oil.
Although water-soluble vitamins are not stored, toxicity may still occur with vitamin megadoses.
The body is unable to synthesize most vitamins in the required amounts and depends on dietary intake.

Answer to Question 2

D
It is recommended that males over the age of 50 undergo a yearly prostate-specific antigen (PSA) blood test to detect prostate cancer.
Twenty years of age does not reflect the current practices for early detection of prostate cancer.
Thirty years of age does not reflect the current practices for early detection of prostate cancer.
Forty years of age does not reflect the current practices for early detection of prostate cancer.
