Eyesight and Food

The bad news just keeps on rolling in. For food that is high on the glycemic index, that is. So much so that you would honestly wonder why anyone would make these foods part of their diet. In another research study, poor eyesight was linked to consumption of food that caused a spike in your insulin levels. Scientifically known as age-related macular degeneration or AMD, this is the gradual progressive weakening of your eyesight due to age. It is one of the leading causes of loss of vision in people fifty and older. It is caused by damage to the macula, a small spot near the retina. The effect can be rapid or slow and cause loss of vision, enlargement of the eyes and blank spots in your vision.

Scientists used mice to test the effect of a healthy diet versus one that had food with a high glycemic index. The mice fed with the unhealthy diet showed all the symptoms of AMD including loss of the function of cells in the back of the eye responsible for capturing light. Interestingly the ones fed the healthy diet did not show the same impairment. Even the small cohort for whom they changed the food mid-way to healthy eating did not show degeneration. The ability to arrest the weakening of your eyesight is excellent news for all those who are still in their thirties or forties and may be heading toward loss of vision.

The research threw up another interesting outcome. The scientists were able to detect the risk of loss of vision by identifying biomarkers (biological evidence of risk). These included advanced glycation end products (AGE’s) formed when sugar metabolises, oxidised fats and high levels of serotonin in your body.
