An antioxidant is something that prevents or

  An antioxidant is something that prevents or slows down oxidation. The normal processes of oxidation produce highly reactive free radicals. These can react with and damage other molecules. In some cases, the body uses free radicals to destroy foreign or unwanted objects, such as in an infection. However, sometimes the body’s own cells may become damaged. If the damage occurs to the DNA, this can lead to diseases such as cancer. To prevent this, antioxidants can decrease the damage done to cells by reducing oxidants before they can damage the cells. This causes the antioxidants to be beneficial in reducing the incidence of cancer, cardiovascular disease, Alzheimer’s disease, stroke, and much more. In addition, oxidants may be encountered from the external environment from pollutants, smoke or alcohol. Antioxidants help the body by neutralizing and removing these oxidants from your bloodstream. Therefore, it’s important to maintain the balance between antioxidants and oxidants in the body for good health.   Not only do antioxidants help reduce the chances of diseases, but can also increase life expectancy as well. A restricted calorie diet can help this happen. As food produces free radicals when metabolized, antioxidant-rich diets are thought to stave off the effects of aging significantly better than diets lacking in antioxidants. Typically, the mitochondria produce natural antioxidants to counteract the effects of free radical production. However, as one age, the membranes of mitochondria become less stable, and these free radicals manage to escape more easily and do much more damage. This is believed to contribute to the effect of “aging” thus making many believe that taking antioxidants can reduce levels of free radicals. Most of the food that many people eat, such as fast food and other food sources high in processed carbohydrates, sugars, and fat, contain very low levels of antioxidants. As well as being low in antioxidants, these items actually increase the cholesterol level, which can lead to some serious health risk.   There are many ways to obtain antioxidants so that a healthy diet and possibly a longer life can be achieved. Effective antioxidant choices are vegetables such as spinach, lettuce, and cauliflower that are rich in antioxidants along with minerals and vitamins Tuberous sweet potatoes, onions, and garlic are other rich sources of antioxidants. Additionally, orange vegetables like carrots are rich in vitamin A and phytochemicals (flavonoids). Flavonoids can be found in a variety of fruits, red wine, and teas. Fruits such as grapes, especially dark grapes, are loaded with antioxidants such as phytochemicals, selenium, and vitamin C, which are helpful in protecting against heart disease and cancer. The antioxidant properties of tea leaves have properties like anthocyanin and proanthocyanidin, which help the body fight inflammation, and quercetin and catechins, with the latter blocking cell damage that could cause cancer.     Even Though there are many options available to get antioxidants, many factors or ingredients have a possibility of decreasing its effectiveness. For instance, take black tea or green tea as an example. Tea, which is a popular drink, is a great source of antioxidants for the body. Many people put additives like milk and sugar in their tea, which can probably cause an effect on the antioxidant levels of green and black tea. Because antioxidants are important in preventing many diseases, this became the main reason to select a project about milk and sugar’s effect on antioxidants in tea.
