Study Notes
Antioxidants are compounds found naturally in some foods, which can prevent or slow damage to cells caused by free radicals. Free radicals are highly reactive molecules with unpaired electrons that can cause cellular damage through oxidative stress. Oxidative stress is associated with various chronic diseases, including cancer, cardiovascular disease, diabetes, arthritis, cataracts, Alzheimer's disease and other forms of dementia, multiple sclerosis, Parkinson's disease, AIDS, and aging.
There are several types of antioxidants, each providing unique health benefits:
- Vitamin C: This water-soluble nutrient neutralizes free radicals called superoxide and hydroxyl radicals, and it also strengthens blood vessels and immune system function.
- Vitamin E: This fat-soluble compound protects cell membranes from oxidation and helps reduce inflammation. It may play a role reducing the risk of heart attack and stroke.
- Beta-Carotene: This plant pigment is converted into vitamin A within the body. It acts as an antioxidant, protecting the body from harmful substances that could cause cancer or heart disease.
- Lycopene: Found in tomatoes, this compound is a powerful antioxidant linked to improved prostate cancer survival and reduced lung, breast and other cancers.
- Polyphenols: These micronutrients provide numerous health benefits, such as anti-inflammatory effects, immune support, neuroprotective action, and protection against chronic diseases like diabetes and cardiovascular disorders.
The role of antioxidants in health is crucial because they help counteract the damaging effects of free radicals, which contribute to many chronic diseases. By consuming a diet rich in antioxidants, individuals can potentially lower their risk of developing these conditions. Additionally, antioxidants have been shown to improve cognitive function, memory, and learning ability in elderly people.
In summary, antioxidants are essential for maintaining good health, protecting against cellular damage, and preventing chronic diseases. Consuming a diverse range of fruits and vegetables is key to obtaining a balanced intake of antioxidants for optimal health.
