For years, scientists have speculated about the role of antioxidants in disease and health. Several diseases and chronic illnesses are thought to be affected by antioxidants. Some of them are heart disease, cancer, Alzheimer’s disease, arthritis, cataracts, Parkinson’s disease and dementia. The following article discusses the many beneficial effects of antioxidants on human health.
In recent years, researchers have discovered that antioxidants may help prevent heart disease, cancer and even Alzheimer’s disease. Antioxidants can be found in several foods, vitamins and herbal remedies. Several foods that are high in antioxidants are: fresh fruits and vegetables, berries, nuts, whole grain cereals, green tea, wine and beer.
When humans are exposed to free radicals (FR), which are byproducts of metabolism, they become vulnerable to infections and disease. Common symptoms of FR include a runny nose, red eyes, irritation and diarrhea. Eating foods that are high in antioxidants can help prevent the development of chronic illnesses and diseases, although scientists are not exactly sure how this is done. Some studies show that antioxidants counter the effects of oxidative stress, which is one of the mechanisms underlying ageing. Antioxidants also help to repair damaged cells, so consuming foods that are high in antioxidants may help delay, or even prevent the aging process.
Vitamin C, as well as beta carotene, is one of the most powerful antioxidants. It has been shown to protect against certain cancers, cardiovascular disease and macular degeneration. Oxidative stress can result in the development of a host of serious health problems, including atherosclerosis, stroke, diabetes, obesity and cancer. Green vegetables, spinach, citrus fruits, broccoli, tomatoes, and peppers are all good sources of vitamin C. However, the richest source of vitamin C is in raw fruits and vegetables, so consuming them is not sufficient to provide your body with adequate amounts of antioxidants. Whole foods, such as green leafy vegetables, are great sources of antioxidants.
Deficiencies in some vitamins can lead to vitamin deficiencies, so it’s important to eat a balanced and healthy diet. Vitamin C supplements can be taken to increase the levels of antioxidants in your body. Taking these supplements regularly can prevent the development of chronic diseases and age-related eye disorders such as vision loss due to the loss of vision caused by free radicals in your system.
A diet that is rich in antioxidants can be obtained by eating plenty of fresh fruits and vegetables, as well as foods that contain a high level of dietary fiber. The best and most complete diet that contains antioxidants is a diet that consists mainly of whole grains, nuts and seeds, as well as legumes, and whole soy products. One of the best natural sources of antioxidants is selenium. High levels of selenium are found in whole grains, nuts, seeds and soybeans, although studies have shown that eating a particular type of salmon (for example, marine salmon) can also provide good sources of selenium. For a good source of vitamin A, consume foods that are high in beta-carotene, such as carrots.
Antioxidant supplements are available in tablet and liquid form. It is advisable to combine antioxidant supplements with a healthy diet, as well as a regular dose of physical exercise. Vitamins A, C and E are considered to be the most important nutrients for fighting damage caused by free radicals, and it is important to get enough of each to achieve good health benefits. It is also important to drink enough water every day, since water helps to neutralize free radicals in the body. Drinking a glass of red wine with each meal may also be beneficial to your health.
Vitamin C, E, and A are all important nutrients in helping to maintain healthy eyesight, as well as reducing the risk of developing age-related eye diseases. Many fruits and vegetables contain antioxidants, and research indicates that these fruits and vegetables may help prevent cancer, as well as keep your heart healthy. In addition to taking antioxidant supplements, eating lots of fruits and vegetables may help to achieve adequate levels of these vitamins. Remember that not all fruits and vegetables are created equally – organic and whole foods are healthier for you than artificial or convenience foods. However, fruits and vegetables do offer plenty of antioxidants that are essential to your health.
