Cataracts, Sugar and N-Acetyl Carnosine

I know that most people think cataracts are just a normal part of aging and can only be corrected by surgery, but this is another myth that should be dispelled. In fact, studies have long correlated excessive intake of sugar and other carbohydrates with cataracts, especially when these happen early in life. For more detailed information on this, I suggest you go to www.nancyappleton.com and also consider reading her book “Lick the Sugar Habit.”

A recent study analyzed data collected in connection with the Nurses’ Health Study and also concluded that there is a direct correlation between the development of cataracts and the amount of carbohydrates in the diet. Interestingly, this study did not find that sugar was any worse or better than other carbohydrates and the only correlation was with total carbohydrate consumption – another good reason to consider limiting carbs in a sensible way!

The other part of the myth is that you have cataracts there is nothing you can do other than surgery. In reality, a growing number of studies performed over more than a decade in different parts of the world and independently of one another have all reached the same conclusion: that an eye drop solution containing the natural antioxidant N-acetyl-carnosine (NAC) can prevent and even reverse existing cataracts. Many of these studies are large double-blind and placebo-controlled studies but, given that NAC is a natural over-the-counter supplement and not a patented drug, we continue to be told that surgery is the only option!
