About oxidation Antioxidants and free radicals The effect of free radicals Disease-fighting antioxidants Sources of antioxidants Vitamin supplements and antioxidants Dietary recommendations for antioxidants Where to get help.

About oxidation The process of oxidation in the human body damages cell membranes and other structures, including cellular proteins, lipids and DNA. Antioxidants and free radicals Antioxidants are found in certain foods and may prevent some of the damage caused by free radicals by neutralising them.

Disease-fighting antioxidants A diet high in antioxidants may reduce the risk of many diseases including heart disease and certain cancers. Sources of antioxidants Plant foods are rich sources of antioxidants. Also derived from the plants that animals eat. Vitamin supplements and antioxidants There is increasing evidence that antioxidants are more effective when obtained from whole foods, rather than isolated from a food and presented in tablet form.

Dietary recommendations for antioxidants Research is divided over whether antioxidant supplements offer the same health benefits as antioxidants in foods.

To achieve a healthy and well-balanced diet , it is recommended we eat a wide variety from the main 5 food groups every day: vegetables and legumes or beans fruit whole grain foods and cereals lean meat, poultry or alternatives such as fish, eggs, tofu, legumes, nuts and seeds dairy and dairy alternatives — mostly reduced fat reduced fat milk is not recommended for children under 2 years.

Other antioxidants include lycopene, carotenoids, lutein, zeaxanthin, anthocyanins , quercetin, glutathione and flavonoids like rutin. As described above, the single most important benefit of antioxidants is counteracting free radicals found inside every human body, which are very destructive to things like tissue and cells.

Free radicals are responsible for contributing to many health issues and have connections to such diseases as cancer and premature aging of the skin or eyes.

The body uses antioxidants to prevent itself from the damage caused by oxygen. Electrons exist in pairs; free radicals are missing an electron. This is their weapon of sorts. Free radicals then damage DNA, cellular membranes and enzymes. Many foods that provide these nutrients also supply antioxidants called lutein and zeaxanthin, nicknamed the eye vitamins , found in brightly colored foods like fruits and vegetables — especially leafy greens and types that are deep orange or yellow.

These antioxidants are believed to be easily transported around the body, especially to the delicate parts of the eyes called the macula and the lens. In fact, there are more than different types of carotenoids found in nature, but only about 20 make their way into the eyes.

Of those 20, lutein and zeaxanthin are the only two macular carotenoids that are deposited in high quantities into the macular portion of the eyes, which is one of the earliest to be damaged during aging.

Research shows that high-lutein sources like spinach are proven to help decrease eye-related degeneration and improve visual acuity.

Similarly, flavonoid antioxidants found in berries, such as bilberries or grapes also great sources of the antioxidant resveratrol , may be especially beneficial at supporting vision into older age.

Perhaps most noticeably, free radicals speed up the aging process when it comes to the appearance and health of your skin. Using antioxidants for skin may help combat this damage, especially from eating sources high in vitamin C, beta-carotene and other antioxidants.

Vitamin A and C have been connected to a decrease in the appearance of wrinkles and skin dryness. Vitamin C, specifically, is a powerful antioxidant that can help reduce the effect of oxidative damage caused by pollution, stress or poor diet.

Vitamin A deficiency has also been linked to skin dryness, scaling and follicular thickening of the skin.

Similarly to how free radicals damage surface skin cells, keratinization of the skin, when the epithelial cells lose their moisture and become hard and dry, can occur in the mucous membranes of the respiratory, gastrointestinal tract and urinary tract.

At this point, the data does not show that all antioxidants are effective in protecting against heart disease, but some, such as vitamin C, do seem to be. The American Journal of Clinical Nutrition featured a study that found those with high levels of vitamin C in their blood had almost a 50 percent decreased risk of stroke.

Countless studies also have found that people who consume highly plant-based diets — loaded with things like fresh veggies, herbs, spices and fruit — have a better chance of living longer and healthier lives with less heart disease.

Some research has unearthed a potential connection between antioxidants and cancer. In fact, studies have found that high intakes of vitamin A, vitamin C and other antioxidant foods could help prevent or treat several forms of cancer thanks to their ability to control malignant cells in the body and cause cell cycle arrest and apoptosis destruction of cancer cells.

Retinoic acid, derived from vitamin A, is one chemical that plays important roles in cell development and differentiation, as well as cancer treatment. Lung, prostate, breast, ovarian, bladder, oral and skin cancers have been demonstrated to be suppressed by retinoic acid.

Another study collected numerous references demonstrating the findings of retinoic acid in protection against melanoma, hepatoma, lung cancer, breast cancer and prostate cancer.

Many studies have found that people eating plant-based diets high in antioxidants, such as the Mediterranean diet , have better protection over cognition. In addition to improving heart health and cognitive function, some research suggests that antioxidants could aid in the prevention of type 2 diabetes.

For example, one animal model out of Japan showed that administering antioxidants to mice helped preserve the function of beta cells in the pancreas, which are responsible for the production of insulin.

Another large review of 12 studies found that vitamin E helped reduce blood sugar levels, while vitamin C was effective at decreasing levels of oxidative stress. Antioxidants may be easier to add to your diet than you might think.

Have you Antioxidwnt-rich wondered what Advanced weight support a blueberry blue? Well, technically blueberries are purple, but that rich color you see comes from anthocyanin pigments, which are found naturally in foods like blueberries. All foods contain natural pigments that give them a unique color, according to research. Beta-carotene makes carrots orange, chlorophyll gives vegetables such as kale and collard greens their verdant color — you get the idea. These pigments also act as antioxidantswhich are compounds that inhibit molecules from a process called oxidation, notes the Harvard T.
