Although the general public consensus is that carrots are good for your eyesight, even if this is considered by some to be based on a myth, researchers have discovered that glaucoma risk gets lowered by eating green leafy vegetables. In other words, the concept that carrots improve your health in regards to your eyes was not that far from the truth, it was simply focusing on the wrong vegetable.
The study was conducted by a research team created from a partnership between Harvard’s Medical School and the Brigham & Women’s Hospital. This analysis focused on documenting how nitrate-containing leafy greens, like spinach, kale, and lettuce can combat the onset of primary open-angle glaucoma.
Glaucoma can be summarized as an infection of the optic nerve, leading to a loss of eyesight. This disease is generally caused by a fluid build-up in the frontal part of the eye that leads to optic nerve damage. Glaucoma is the main source of blindness in senior adults and over 3 million US citizens have been diagnosed with this illness up to this point.
As with most statistics-based studies, this analysis of over 100,000 US adults gave a result that is based on correlation, not cause and effect. Because of this, the general public should still take the idea of a high nitrate intake directly combating glaucoma with a pinch of salt.
Out of the study participants, 1,500 of them developed glaucoma, while the ones who had a diet consisting of leafy greens rich in nitrates had a 30% risk decrease towards developing this disease. The follow-up checks, made every two years, further cemented the concept that nitrate-based vegetables combat the onset of glaucoma, but further clinical studies made in a controlled environment must be conducted in order to provide a more conclusive result.
Even if this theory is still viewed with a degree of skepticism from several parties, be they medical teams or just the general public, this does not mean that one should not opt for a vegetable-based diet. Although your eyesight may not improve that much, your general health will benefit greatly from a better and a more healthy lifestyle.
If the finding claiming that glaucoma risk gets lowered by eating green leafy vegetables is proven to be correct after more conclusive clinical trials and analysis are conducted, people will have yet another reason to adopt a vegetable-based diet.
