It is common to hear experts recommending foods rich in antioxidants such as astaxanthin, resveratrol, or beta- carotene, because of their health effects. There are two types of antioxidants:Lipid-soluble antioxidants – including vitamin E and A, carotenoids, and lipoic acid – are present in your cell membranes, while water-soluble antioxidants (such as vitamin C, polyphenols, and glutathione) are found in your blood and the fluids around your cells.
The best sources of antioxidants are food, especially in their organic and unprocessed forms. These are more preferred than using oral antioxidant sources such as a vitamin A or an astaxanthin supplement.Carotenoids are referred to as pigments because they induce color.Vitamin A, carotene, and xanthophylls are carotenoids that give redand yellow fruits their color.
Zeaxanthin and lutein, which are also pigments, are found in greenleafy vegetables such as spinach, kale, and egg yolks.Astaxanthin, which is a popular carotenoid, is found in salmon andkrill. This antioxidant is actually responsible for turning these speciespink.
Another water-soluble antioxidant is anthocyanin. This nutrientis found in berries such as bilberries and black currant. Nuts arealso good sources of antioxidants.Vitamin E can actually be found in almonds. Peanuts are alsoa good source of resveratrol, a type of polyphenol.
Apart from peanuts, raw cacao and red wine are other sourcesof resveratrol. However, resveratrol is most concentrated inmuscadine grapes – specifically in their thick skin and seeds.Other polyphenols are often concentrated in green tea. VitaminC, another lipid-soluble polyphenol, can be found in citrus fruits.
