How antioxidants kill cancer cells?

How antioxidants kill cancer cells?

But antioxidants can be used to kill cancer, at least in rodents. High concentrations of the “antioxidant” ascorbate, achievable only by injection in vivo, result in the production of ascorbate radicals and hydrogen peroxide in the extracellular fluid that kills cancer cells, but not normal cells.

How do antioxidants protect against disease?

Antioxidants are substances that may protect your cells against free radicals, which may play a role in heart disease, cancer and other diseases. Free radicals are molecules produced when your body breaks down food or when you’re exposed to tobacco smoke or radiation.

What do antioxidants reduce the risk of?

Disease-fighting antioxidants A diet high in antioxidants may reduce the risk of many diseases (including heart disease and certain cancers). Antioxidants scavenge free radicals from the body cells and prevent or reduce the damage caused by oxidation.

Do antioxidants reduce risk of disease?

Antioxidants prevent oxidative stress and have been thought to help reduce risk of cancer, diabetes, Alzheimer’s disease, and other conditions. This is one reason why fruits and vegetables, which are generally rich sources of these nutrients, are universally recommended.

Can antioxidants cause cancer?

There was a time when it was thought that antioxidant supplementation could be a major breakthrough for disease treatment and prevention. But recently, two studies have found evidence that antioxidants may cause lung cancer cells to spread.

What is the strongest antioxidant?

Vitamin E: more than nature’s most powerful antioxidant

  • Summary.
  • Introduction.
  • Oxidative stress and antioxidant system.
  • Vitamin E Metabolism.
  • Vitamin E is the most powerful antioxidant of lipid membranes.
  • Conclusion: higher levels of vitamin E have multiple benefits.

What vitamins fight free radicals?

Although there are several enzyme systems within the body that disarm free radicals, the principal antioxidants are vitamin E, beta-carotene, vitamin C, and selenium. When these antioxidants neutralize free radicals by donating an electron particle they are left with a small problem.

What fruit is high in antioxidants?

Many fruits are high in antioxidants, packed with vitamins, and beneficial in a myriad of ways. These include cranberries, red grapes, peaches, raspberries, strawberries, red currants, figs, cherries, pears, guava, oranges, apricots, mango, red grapes, cantaloupe, watermelon, papaya, and tomatoes.

What are the best antioxidants for cancer?

This vegetable family contains powerful phytochemicals, including carotenoids, indoles and glucosinolates and isothiocyanates, which have been studied and shown to slow the growth of many cancers.

What antioxidants fight cancer?

Free radical damage may lead to cancer. Antioxidants interact with and stabilize free radicals and may prevent some of the damage free radicals otherwise might cause. Examples of antioxidants include beta-carotene, lycopene, vitamins C, E, and A, and other substances.

Which fruit is highest in antioxidants?

  • Raspberries – 4 mmol antioxidants per 3.5 ounces serving.

What foods are high in free radicals?

1) Avoid high glycemic foods, or foods that are rich in refined carbohydrates and sugars. They are more likely to generate free radicals. 2) Limit processed meats such as sausages, bacon and salami. They contain preservatives, which leads to the production of free radicals.
