Roles of Antioxidants
Roles of antioxidants. They are vital substances that are important for preserving our health and well being. These compounds, which are present in a wide range of foods, aid in shielding the body from harm brought on by dangerous molecules called free radicals. Knowing what antioxidants are, how they function, and their advantages can help people make dietary decisions that will improve their general health.
ROLES OF ANTIOXIDANTS
Molecules known as antioxidants prevent other molecules from oxidizing. A chemical process called oxidation can create free radicals, which can start a chain reaction that harms cells. Unstable chemicals known as free radicals can lead to oxidative stress, which ages people and causes a number of illnesses, such as cancer, heart disease, and neurological conditions.
Types of Antioxidants
Antioxidants come in various forms and can be categorized into several types:
1. Endogenous Antioxidants:
These are produced naturally by the body and include enzymes like superoxide dismutase, catalase, and glutathione peroxidase.
2. Exogenous Antioxidants:
These are obtained from the diet and include:
– Vitamin C :
Found in citrus fruits, strawberries, and bell peppers.
– Vitamin E:
Found in nuts, seeds, and green leafy vegetables.
– Beta-Carotene and Other Carotenoids:
Found in colorful fruits and vegetables like carrots, sweet potatoes, and spinach.
– Polyphenols:
Found in tea, coffee, red wine, chocolate, and many fruits and vegetables.
– Selenium:
A trace mineral found in nuts, seafood, and meats.
How Antioxidants Work;
Antioxidants neutralize free radicals by donating an electron, thereby reducing their reactivity. This process helps to prevent the free radicals from causing cellular damage. The body relies on a balance between free radicals and antioxidants to maintain optimal physiological function. An imbalance, with more free radicals than antioxidant, leads to oxidative stress.
Benefits of Antioxidant;
Antioxidants offer a wide range of health benefits, primarily through their ability to combat oxidative stress and support overall cellular health. Here are some of the key benefits:
1. Prevention of Chronic Diseases:
By neutralizing free radicals, antioxidant help reduce the risk of chronic diseases such as cancer, cardiovascular diseases, and neurodegenerative disorders like Alzheimer’s and Parkinson’s disease.
2. Immune System Support:
Antioxidants boost the immune system by protecting immune cells from damage, thereby enhancing the body’s ability to fight off infections and illnesses.
3. Skin health;
Antioxidants such as vitamins C and E protect the skin from damage caused by ultraviolet (UV) radiation and pollution, reducing the signs of aging, such as wrinkles and age spots.
4. Eye Health:
Certain antioxidants, like lutein and zeaxanthin, are essential for eye health and can help prevent age-related macular degeneration and cataracts.
5. Anti-Inflammatory Properties:
Many antioxidants have anti-inflammatory properties, helping to reduce inflammation throughout the body. This can be particularly beneficial for conditions like arthritis and other inflammatory diseases.
6. Heart Health:
ROLES OF ANTIOXIDANTS
Antioxidants help improve heart health by preventing the oxidation of low-density lipoprotein (LDL) cholesterol, which can reduce the risk of atherosclerosis (hardening of the arteries) and subsequent heart attacks or strokes.
Sources of Antioxidant;
A diet rich in antioxidants is essential for maintaining good health. Here are some foods that are high in antioxidant:
– Fruits: Berries (such as blueberries, strawberries, and raspberries), citrus fruits, grapes, apples, and cherries.
– Vegetables: Leafy greens (such as spinach and kale), bell peppers, broccoli, carrots, and sweet potatoes.
– Nuts and Seeds: Almonds, walnuts, sunflower seeds, and flaxseeds.
– Beverages: Green tea, black tea, coffee, and red wine (in moderation).
• Others: Dark chocolate, whole grains, and legumes.
