Antioxidants are chemicals that help stop or limit damage caused by free radicals. Your body uses antioxidants to balance free radicals. This keeps them from causing damage to other cells. Antioxidants can protect and reverse some of the damage. They also boost your immunity. You can help fight and reduce free radicals and the damage they cause. You can stop smoking, get sun exposure safely, and eat healthy. Antioxidants may also help.
Your body produces some antioxidants. The best way to get antioxidants is through certain foods and vitamins. Common antioxidants include:. You can get most of these antioxidants by eating a healthy diet. This includes a mix of colorful fruits and vegetables. Whole grains, seeds, and nuts also provide good nutrients. Each antioxidant has a different chemical makeup. Each one provides different health benefits.
Too much of one antioxidant can be harmful. Talk to your doctor before changing your diet or taking supplements. Doctors recommend eating a balanced diet that include fresh fruits and vegetables. A lot of produce has natural antioxidants.
It also contains minerals, fiber, and other vitamins. Eating healthy can help lower your risk of certain diseases. However, antioxidants alone do not prevent chronic conditions.
Some people choose to take antioxidant supplements. However, many are not balanced. They are also not approved or regulated by the U. This article contains content that is no longer available. It's not just food: antioxidant supplements line the shelves of supermarkets, chemists and health food stores, promising to hold back the tides of ageing and chronic disease.
Yet research shows antioxidants don't always live up to the hype when it comes to delivering health benefits. Even more concerning is the evidence that shows taking antioxidant supplements can sometimes do more harm than good. To understand antioxidants, first we must understand oxidants — better known as free radicals. Free radicals are natural by-products our cells create when they convert food into energy.
They're a normal part of the way our bodies function, and natural oxidants are easily tolerated. We also encounter free radicals in many aspects of our daily lives.
Sunlight triggers the formation of free radicals in our skin and eyes; they are also in the food we eat and the air we breathe. Cigarette smoke, pollution, alcohol and stress can also contribute to the development of free radicals. What makes free radicals nasty is that react with whatever molecule they bump into. This reaction is called oxidation, and much like the oxidation that causes iron to rust or a cut apple to brown, it causes damage. The damage caused by free radicals is thought to be one of the key contributors to the gradual deterioration of your body that comes with ageing.
It can affect the protective membranes that envelope each of our cells, as well as the proteins and DNA molecules inside each cell. Dr Beckett said the damage caused to DNA by free radicals can cause cell mutations and promote cancer. Free radicals can also oxidise low-density lipoprotein LDL or "bad cholesterol" , making it more likely to collect in artery walls, harden blood vessels and lead to cardiovascular disease.
Given the constant barrage of free radicals your body encounters, it's not surprising that you come equipped with some defence molecules. This brings us back to antioxidants. It's like a chain reaction. So they're halting that negative chain reaction. Hundreds of substances are known to behave as antioxidants in the presence of free radicals.
