Snacks may impair vision

A new study shows that unhealthy foods not only increase the waist circumference, but may also impair vision.

Researchers at the Eye and Ear Hospital of Massachusetts noted that excessive retail sales of high fat content, such as margarine, chocolate, cakes, potato chips, nuts, etc., may increase the chance of developing advanced age-related macular degeneration. In the United States, this eye disease is the leading cause of blindness and visual impairment in people over the age of 55.

Prior to this, smoking was the only known risk factor causing retinal macular degeneration.

The study concluded that certain types of fats, especially fats in chemically-added, sugar-rich foods, can increase the chances of bulimia patients suffering from the disease more than twice.

The monounsaturated and polyunsaturated fats and linoleic acid contained in the refined foods sold in the stores belong to such fats.

However, as long as you maintain a low intake of linoleic acid, eating more fish rich in omega 3 fatty acids can reduce the risk of suffering from this disease, such as tuna and salmon. Eat more green leafy vegetables can also achieve the same effect.
