It is a known fact that fruit and vegetables are essential for a healthy diet, because they are full of anti-oxidants are substances or nutrients in our foods which can prevent or slow damage to our bodies. When our cells use oxygen, they naturally produce free radicals, by-products may cause damage. Antioxidants act as "free radicals, prevent and repair damage. Health problems such as cancer is caused by oxidative damage. Scientists are busy discoveringthe hardest working antioxidants in our diet and how they work. Green TeaIn the last 15 years, tea has become one of the most studied food. Researchers believe the health benefits of tea are due to polyphenols, which are powerful antioxidants. Flavonoids, a type of polyphenols, the most effective and catechins, a type of flavonoid, play a role in cancer prevention. All teas, caffeine free, and the tea is drunk hot or cold, these substances, but the amounts varyby type and how much a cup of tea brewed. Another antioxidant in green tea, EGCG has been shown to latch on a protein in the tumor cells and inhibit cell growth. The amount of green tea used in the study was not much, comparable to the amount found in the body after drinking two cups.
While both green and black teas offer health benefits, green tea deal more punch. All varieties of tea from the same plant. The difference is in howThe leaves are treated after they are picked. For black tea, fresh leaves are rolled and then may wither before the doors, which most of the active substance causes oxidation. Green tea leaves are steamed to preserve the natural active substances, and thus gives more antioxidants. Indeed, based on in vitro studies, flavonoids in a cup of green tea has higher antioxidant activity than an individual portions broccoli, carrots, apples or grapes.
Green tea is also a morehealthy drink or coffee or alcohol. Fresh green tea is completely natural and contains no fat, calories, alcohol or sugar (if it unsweetened and without milk.) A cup of green tea has about half the caffeine in a cup of coffee.
Citrus Fruit Eating just one orange a day will reduce the risk of certain types of cancer in half. Oranges contains over 170 antioxidants, flavonoids and sixty of them. Citrus fruits also strengthen the immune system, which inhibits tumorand normalizes tumor growth.
Tomatoes Tomatoes are colored by lycopene, which has proved extremely useful to the chances of men from prostate cancer reduction. Indeed, researchers have recommended lycopene grants used to supplement standard prostate cancer treatment with surgery, chemotherapy and radiation. Lycopene has also shown that DNA damage that can precede prostate cancer in African-American men.
If you want the mostanti-cancer benefits by tomatoes, cook them. Heat treatment was indeed the amount of lycopene, which can be absorbed by the body and its anti-oxidant activity to increase.
Other fruit and vegetable Americans not eating enough fruit and vegetables tend not to go too much black. Iceberg lettuce, corn, apples, potatoes and bananas not give many cancer-fighting punch. To get health benefits and risks of the disease, we should eat more variety.Cauliflower, lettuce dark (ie, Roman or red leaf), spinach, broccoli, are sprouts, carrots, pumpkin, sweet potatoes, melon, red peppers and strawberries already high in antioxidants and has shown that the disease preventive properties.
SeleniumThe mineral selenium has been found for esophageal, skin, rectal and prostate slow. Researchers study the blood levels of selenium found that people with less selenium was three times more likely to have precancerousgrowth rates than those with more selenium. They believe that selenium inhibits the growth of abnormal cells, preventing genetic damage and help the body to destroy tumor cells that would otherwise be. Foods with selenium include tuna, oysters, shrimp, salmon, brazil nuts, liver, pork and turkey.
Less meat, dairy and alcohol, scientists have found that premenopausal women who ate the most fat red meat and milk, had a 54% greater chance of developing invasive breast cancer than thosewho ate less meat. Scientists believe that eating more saturated fats from meat increases hormone levels, reduce the potential for breast cancer increases.
A 2003 study also showed that post-menopausal women, who average two alcoholic drinks a day increased breast cancer risk by 80%. Again, the researchers believe that alcohol affects the levels of hormones that affect cancer.
