Cancer-fighting vitamins -

Verdict: Drinking up to three cups of green tea per day is probably safe for most people and may have anticancer effects. However, green tea extracts or pills are not recommended. Be aware that green tea contains caffeine, which may interact with medications and keep you awake.

Charge: Lycopene is a plant chemical called a carotenoid. Research has shown that lycopene in food appears to reduce prostate cancer risk; however, this remains controversial. Verdict: Once again, we don't know how lycopene works in the body -- or whether it's working alone -- to reduce cancer risk.

Consider this: Researchers noted that foods rich in beta-carotene -- a cousin to lycopene -- seemed to reduce lung cancer risk in smokers. But when beta-carotene supplements were tested by smokers as a preventive, cancer risk increased.

Leave lycopene supplements alone. Instead, eat more tomato sauce, low-sodium tomato juice, watermelon, guava, rose hips and pink grapefruit. Charge: Melatonin is a hormone found in the body. Doctors sometimes prescribe a synthetic form of it to supplement cancer treatment or ward off side effects.

Melatonin also is used to treat insomnia. Research is under way to determine whether melatonin helps boost the immune system. Verdict: If you are having problems sleeping, it might be worth talking to your doctor about melatonin.

However, do not take this supplement -- or any other -- without consulting your doctor first. Some melatonin supplements may contain contaminants. Melatonin is known to interact with certain medications -- including blood pressure drugs -- and may worsen depression.

Charge: Resveratrol is a polyphenol known to act as an antioxidant, an antiinflammatory and a weak plant estrogen. These properties may help it to prevent cellular damage known to trigger cancer, but its ability to slow the growth of cancer cells has only been shown in early laboratory testing.

Verdict: Resveratrol is found in grape skins, so eat more red and purple grapes. It's too soon to know how resveratrol works or whether resveratrol supplements are safe, so don't take resveratrol pills -- or uncork the red wine.

While it's true that resveratrol is found in wine, it's also true that alcohol consumption is associated with increased cancer risk. Resveratrol may have an estrogenic effect, so women with hormone-sensitive conditions, in particular, should avoid resveratrol supplements. Charge: Selenium is a mineral found in poultry, fish, wheat and liver.

It was once thought to be potentially beneficial in preventing cancer. However, several studies have shown that it is not only ineffective, but also potentially dangerous.

Studies have shown it does not prevent skin, lung, prostate, stomach and esophageal cancer. Furthermore, research conflicts as to whether it may increase risk for a type of skin cancer called squamous cell carcinoma.

Last year, a trial examining vitamin E and selenium for prostate cancer prevention was halted after researchers noted a small increase in diabetes among men who took selenium.

Charge: Turmeric, a curry spice, has anti-inflammatory properties and contains an antioxidant called curcumin. In very early basic laboratory studies, curcumin has been shown to stop the spread of melanoma cells.

However, researchers do not know whether curcumin has any anticancer effects in humans. Verdict: A recent study showed turmeric may interfere with chemotherapy for breast cancer, so avoid turmeric during chemo. Turmeric supplements also may worsen gallbladder problems or slow blood clotting.

If you have finished treatment and want to learn how to use turmeric as a spice, try our recipes featuring tumeric. Never take a supplement without talking to your doctor first. They may cause dangerous interactions with medications or lessen the effectiveness of cancer treatment.

Charge: Vitamin D to reduced cancer risk. Vitamin D helps control cell growth and holds promise for cancer prevention. Verdict: Research hasn't determined what dose of Vitamin D is effective -- and safe -- for cancer prevention. In the meantime, eat oily fish along with milk and fortified cereals.

Isoflavones are chemicals in soy products that are known for their health benefits. It is very similar to the hormone oestrogen. Oestrogen can stimulate some cancers, such as breast cancer, to grow. People often worry that foods or soy supplements containing isoflavones might have the same effect as oestrogen and cause cancer to grow.

But current research says that foods containing natural isoflavones are safe. Early studies also show that isoflavones may have some benefits in certain cancers. It may:. In breast and prostate cancer isoflavones may reduce the risk of cancer coming back.

This is because isoflavones are similar to the hormone oestrogen and bind to the oestrogen receptors on cells. By doing so, it blocks cancer cells from absorbing oestrogen. However, these studies are based on Asian diets that contain large amounts of soy.

Soy can be a meat free source of protein and fibre in your diet. One trial showed that selenium might protect against the overall risk of prostate cancer in men with a history of non melanoma skin cancer.

But a later systematic review found that selenium supplements had no benefit in protecting against cancer. Some randomised controlled trials showed a higher incidence of high grade prostate cancer and type 2 diabetes in people taking selenium supplements. Research in this area has produced mixed results.

Doctors don't recommend that people take it to treat cancer or reduce the risk of cancer. People often take vitamin C in much higher doses than the recommended nutrient intake RNI of 40mg per day. Some people take it as a drip into the bloodstream IV.

There is no good quality research to say that vitamin C helps chemotherapy to work better or help to reduce its side effects. Research continues to look at the role of vitamin D in the development and recurrence of different cancers. Some early studies suggest that there is a link between low levels of vitamin D and the development of cancer.

However, vitamin D is important for keeping our bones healthy. We need it to absorb calcium. Most of our vitamin D comes from sunlight, but some comes from our diet. The Government recommends that all people in the UK consider take 10 micrograms of vitamin D in the autumn and winter.
