Antioxidants help limit free radicals the cause of health deterioration
Free radicals are molecules or atoms that have lost electrons, causing their energy to become unstable.
Therefore, they induce reactions to steal electrons from other molecules, resulting in changes in the structure of other molecules. Free radicals can occur from both internal and external factors of the body.
Free radicals are caused by สมัคร UFABET วันนี้ รับเครดิตฟรีสำหรับสมาชิกใหม่ external factors. That cause more free radicals in the body, such as UV rays, smoke pollution, smoking, bacterial or viral infections.
Eating fried, grilled or stir-fried foods, as well as physical stress (lack of sleep, fasting to lose weight, heavy exercise), etc.
Antioxidants help eliminate these wastes. In order to prevent or reduce oxidative stress. In addition to making healthy lifestyle changes, eating a healthy diet rich in antioxidants is also important.
3 types of antioxidants
Vitamin A
Including precursors that can be converted to vitamin A (Vitamin A precursors). Divided into 2 groups: the carotenoid group (Carotenoids) such as Beta-carotene, Alpha-carotene, Beta-cryptoxanthin and the retinoid group (Retinoids) such as Retinol Esters, Retinal, Retinoic Acid, etc. and precursors of vitamin A have the ability to capture free radicals (Peroxyl Radical Scavenging) and inhibit the process of creating free radicals from fat. Carotenoids with at least 11 double bonds are 5 times more effective in resisting free radicals than the retinoid group.
Foods high in vitamin A include meat, eggs, milk and dairy products.
Foods high in carotenoids include yellow and orange vegetables and fruits, such as carrots, pumpkins, and papaya.
Vitamin C (Ascorbic Acid)
Vitamins that have good antioxidant properties. They can donate electrons to substances that will become free radicals, thus reducing the level of free radical formation.
Food sources high in vitamin C include vegetables and fruits such as bell peppers, kale, broccoli, cauliflower, peas, tomatoes, potatoes, and local Thai vegetables such as neem shoots, hemp leaves, and sweet basil.
Vitamin E (Tocopherol)
It is divided into four subgroups: Alpha, Beta, Gamma and Delta. All these subgroups differ in the position of the methyl group. They have anti-inflammatory effects due to their ability to inhibit the inflammatory substances Prostaglandin E2 (PGE2) and Leukotriene B4 (LTB4) in endothelial cells, Macrophages and Neutrophils.
