It is estimated that around one million blind and visually impaired people live in Germany. Impaired vision has very different causes. Vegetables and fruits seem to have a positive influence on some of these diseases.
Causes of changes in vision
The most common cause of blindness is age-related macular degeneration (AMD), followed by glaucoma, ocular changes in diabetic retinopathy and cataracts.
Especially older people are affected by the visual disturbances, which are associated with a significant loss of quality of life: Although many older people with senile deficiency are often still able to cope with their immediate environment, they gradually lose their ability to read and drive and have difficulty recognizing People.
Nutrients for strong eyes
With regular ophthalmological checks, especially with known risk factors and pre-existing diseases, changes in the eye can be detected early and their progress delayed. Whether the regular intake of fruits and vegetables protects is not very clear, but at least for some of the clinical pictures very likely. The positive influence of the AMD is considered assured.
Several studies have shown that carotenoids, especially lutein and zeaxanthin, as well as vitamin A protect the macula, the area of the sharpest vision on the retina. These substances are found mainly in dark leafy vegetables such as kale, spinach and carrots.
However, other antioxidants such as vitamins C and E as well as zinc appear to reduce the risk of developing macular degeneration. The same applies to cataract in cataracts - even these appear to be much less common with the regular intake of fruits and vegetables.
Other foods for healthy eyes
The following are recommended in addition to the above mentioned foods:
- Citrus fruits (especially organs)
- vegetable oils
- Dairy products
A balanced mixed diet not only serves the eyes, but also a fundamentally healthy way of life. Whether additional vitamin and mineral preparations have a preventive effect, about the researchers at a distance.
On the emergence of diabetic retinopathy and glaucoma, the fruit and vegetable intake seems to have no influence on current knowledge.
