Famous antioxidant research scientist Dr. Lester Packer, PhD., believes that degenerative diseases like cancer and heart diseases indicate aging since the body’s immune system becomes weak because of the presence of too many free radicals in the body. Free radicals are easily killed by antioxidants.

Antioxidants are group of different chemical substances whose primary function is to boost the immune system and delay the signs of aging by attacking the harmful free radicals in the body. Four powerful antioxidants are naturally found in foods like fruits and vegetables.
Vitamin E, a known antioxidant, neutralizes the free radicals in the body that were produced during the oxidation process. Oxidation is a process when oxygen is used to break down the body’s tissues. Enough supply of vitamin E in the body delays aging since free radicals get the electrons of Vitamin E and leave the healthy cells in the body to prevent the tissues from being damaged.
It also enhances the body’s immune system and prohibits certain diseases. This vitamin prevents the clogging of arteries and allows blood to flow easily through arteries to prevent the occurrence of cardiovascular problems. It lowers the risk of cancer by stopping carcinogenic nitrosamines, which can be found in some foods, from forming in the stomach. Common food sources include nuts, whole grains, wheat products, vegetable oils, and dark leafy green vegetables like broccoli.

Vitamin C destroys the free radicals in the body, which can also be drawn from external sources such as stress and pollution, repairs damaged tissues, boosts the immune system, helps strengthen teeth and bones, and speeds up the healing of wounds. It also prevents the oxidation of low-density lipoprotein cholesterol (LDL-C) or the bad cholesterol which is the root of atherosclerosis and other cardiovascular ailments. Foods that are rich in vitamin C are citrus foods such as orange and lemon, dark leafy green vegetables like spinach, tomatoes, peppers, and berries.
Beta-carotene is known as the pro-vitamin A since the body converts this to vitamin A when needed. It helps improve and maintain healthy skin and eyes, strengthens bones, lessens the physical signs of aging, and stimulates the immune cell macrophages that can kill cancer cells. Carrots, green leafy vegetables, pumpkin, sweet potatoes, and tomato are good sources of beta-carotene.
Selenium activates prostaglandins that are responsible in regulating blood pressure and the production of glutathione, another antioxidant. It boosts the immune cell activity in order to delay the growth of tumors in the body, thus preventing cancer. Its anti-inflammatory property also helps relieve the pain of people with arthritis. Well-known foods that have high selenium content include brown rice, chicken, eggs, garlic, onion, whole grains, seafood, and vegetables.
