That is why you should support your vision naturally as early as possible. It starts with your diet. Learn why blueberries are a power food for your eyes.
Blueberries: The king of berries for the eyes
Berries should always be on your menu. Blueberries, huckleberries, bilberries – call them what you will, they undoubtedly belong in a balanced diet. Wondering where to find so many exotic berry varieties? Don't worry, all these synonyms refer to a single berry: the good old blueberry. And it contains many antioxidants, which in turn benefit your vision.
The secret of the blue color
Blueberries are not only suitable for making delicious compote or as an ingredient for famous blueberry muffins. Their real strength lies in the plant pigments they contain, the anthocyanins, which give them their dark blue color and stain your mouth and teeth red to purple when eaten. Anthocyanins are found in the outer layers of red, violet, blue, or blue-black fruits and vegetables, which include the blueberry. They belong to a subgroup of flavonoids that have an antioxidant effect and can neutralize free radicals in the body.
Free radicals – they act just like they sound
Free radicals are natural metabolic intermediates of oxygen metabolism that are formed in the body during energy production or as part of the immune response. Due to their highly reactive and unstable properties, free radicals can functionally restrict or even destroy the body's cell structures, enzymes, or proteins. These are also active in the fine blood vessels of the eye. Therefore, if present in excess, they represent a potential danger to the organism and to vision.
