Antioxidants are substances that can help protect cells from damage caused by free radicals. Examples of antioxidants include vitamins C and E, selenium, and carotenoids such as beta-carotene, lycopene, lutein, and zeaxanthin. Three of the main antioxidant vitamins are beta-carotene, vitamin C, and vitamin E. These vitamins can be found in colorful fruits and vegetables, especially those with purple, blue, red, orange, and yellow tones.A diet rich in fruits and vegetables is beneficial for protecting against disease.
Plant-based foods are the best sources of antioxidants, including fruits, vegetables, whole grains, nuts, seeds, herbs and spices, and even cocoa. Eating a diet with lots of vegetables and fruits is healthy and reduces the risk of certain diseases.Vitamin C helps promote wound healing and the production of collagen, the connective tissue that holds bones and muscles together. Vitamin A (beta-carotene) has been linked to a reduced risk of certain types of cancer. Biotin is a member of the B vitamins and plays a crucial role in sugar and fat metabolism.
Vitamin B12 is essential for the maturation of erythrocytes during the production of red blood cells.Vitamin D deficiency is associated with many disorders such as osteoporosis, rickets, osteomalacia, loss of balance, diabetes, rheumatoid arthritis, asthma, depression, epilepsy, and decreased immune function. Vitamin A is not a popular antioxidant but has been reported to have an indirect antioxidant role. Vitamin K is found in foods such as vegetable oils, nuts, seeds, wheat germ, and leafy green vegetables.Therefore, due attention should be paid to these neglected vitamins in research activities on oxidative stress, nutrition and the treatment of diseases related to oxidative stress. Alpha-tocopherol has received the most attention among vitamin E with antioxidant potential but some studies suggest that tocotrienols may have different health-promoting capabilities.
