Antioxidants:Why they are essential for health?
Antioxidants are one of the most important defense mechanisms in the body against the harmful effects of free radicals. Free radicals are compounds that can damage processes in the body if their levels in the body become too high. Excess free radicals are linked to several diseases, including diabetes, heart disease and cancer. However, antioxidants are substances that protect our body against the development of chronic diseases. In this blog post, we will explore what antioxidants are, how they work, and what potential benefits they offer.
What Are Antioxidants?
Antioxidants are compounds that can neutralize free radicals—unstable molecules that can damage cells, proteins, and DNA. Free radicals are naturally produced in the body through metabolism, but they are also generated by external factors.
For example, free radicals can be caused by smoking, unhealthy diet, air pollution and infections.
The main antioxidants that are considered essential are:
- Vitamins: Vitamin E and Vitamin C
- Minerals: Selenium and zinc
- Phytonutrients:: Carotenoids and flavonoids
How Do Antioxidants Work?
When the level of free radicals in the body becomes too high, oxidative stress occurs, leading to cell damage and the development of diseases like cancer, cardiovascular diseases, diabetes, and neurodegenerative disorders such as Alzheimer's.
Antioxidants act like a "defense army," donating electrons to free radicals, neutralizing them before they can damage cells and tissues. This process helps maintain the balance between free radicals and antioxidants.
Health Benefits of Antioxidants:
- Cardiovascular Health: Antioxidants like Vitamin C and Vitamin E help reduce arterial damage that can lead to cardiovascular diseases. They help lower inflammation and keep blood vessels healthy.
- Skin Care: Antioxidants like beta-carotene and coenzyme Q10 are often used to support skin health. They protect the skin from UV damage and help slow down the aging process.
- Immune System Support: Antioxidants play a crucial role in strengthening the immune system, aiding the body's ability to fight infections and diseases. Vitamin C is known as one of the most powerful immune boosters.
- Brain Health: Studies have shown that antioxidants can help protect the brain from oxidative damage associated with aging and neurodegenerative diseases. Flavonoids and polyphenols, found in berries and green tea, may support cognitive function.
Sources of Antioxidants
The best way to get antioxidants is by consuming a varied and balanced diet rich in fruits and vegetables. It is recommended to eat at least 500g of vegetables and 200-400g of berries/fruits daily. Some of the best sources of antioxidants include:
- Berries (e.g blueberries, raspberries, strawberries, blackcurrant)
- Green tea
- Dark leafy greens (eg. spinach, kale)
- Cruciferous vegetables (e.g. broccoli, cauliflower, radish)
- Nuts and seeds
- Dark chocolate
Do We Need Supplements?
While nutrition plays a central role, supplements can be beneficial, especially when it's challenging to get enough antioxidants from food alone. The NutriDream e-shop has a selection of antioxidants:
- Vitamin C with bioflavonoids and rosehip (1 capsule contains 1000mg of vitamin C, 25mg of Citrus bioflavonoids, 20mg of roseships powder)
- Zinc (20 mg) with Vitamin C and Broccoli (1 capsule contains 20mg of zinc and 300 mg of vitamin C)
Antioxidants are crucial for neutralizing free radicals and reducing oxidative stress in the body. Maintaining strong antioxidant levels through diet and, when necessary, supplements can help improve overall health, protect against chronic diseases, and support the body's youthful vitality and energy.
Taking care of your health through a balanced diet and high-quality supplements is a simple step that can provide long-term benefits!
