Carrots: are they really good for the eyes?
"Bunnies don't need glasses because they like to eat carrots." Most people have probably heard a saying like this before. But is it really true that carrots are good for the eyes?
Healthy vegetables Carrots are rich in various vitamins and minerals and also have few calories. They also provide a lot of fiber and are therefore good for digestion. So the vegetables are always healthy. But are carrots really good for the eyes, as is often said? "Carrots contain vitamin A, the lack of which can lead to night blindness, dehydration of the cornea and even melting," said Prof. Gisbert Richard from the Ophthalmology Clinic at the University Medical Center Hamburg-Eppendorf to the dpa news agency. "Vitamin A does not make the eyes better, but a deficiency can have bad consequences for eyesight".
Valuable vitamin A As the agency writes, vitamin A is an important component of the visual pigment rhodopsin. It is also used to maintain the normal cell structure of the cornea. A vitamin A deficiency can arise, among other things, from a one-sided diet or from diarrhea. Then, according to the information, it helps to swallow vitamin A in the short term. As the expert said, in the long term, if there is a deficiency, the diet must be changed. Foods that also contain vitamin A in addition to carrots include pork liver and color-intensive vegetables such as spinach, kale or lamb's lettuce.
Cosmetics with vitamin A You can also get too much of the vitamin. For example, the Federal Institute for Risk Assessment (BfR) warned last year that vitamin A intake via cosmetic products was too high. As was announced at the time, an excessive intake of vitamin A can lead to headaches and nausea, with a chronically high intake even liver diseases and scaling of the skin. Therefore, the additional intake by cosmetics with vitamin A should be limited. (ad)
