Eggs Can Prevent AMD

Age Related Macular Degeneration(AMD) is a leading cause of blindness when we get older. Most blindness occurs at the age of 65 or older. It affects the macula which is responsible for our central vision.

Oxidative stress can help deteriorate the macula. Antioxidants like lutein and zeaxanthin dominates the area of the retina helping prevent oxidative stress by scavenging free radicals. Depletion of these antioxidants can result in a higher risk of acquiring AMD.

To maintain a constant supply of lutein and zeaxanthin, it is wise to include a diet which includes these antioxidants. Egg is a good source of these antioxidants.

Contrary to popular ads that eggs are not good because it produces LDL(low level density lipoproteins) or 'bad' cholesterol in the blood, several studies has proven it otherwise. Some findings when egg is taken daily are:

1. The size of both LDL and HDL(high level density lipoproteins) circulating in the blood was larger in size. Larger sized LDL prevents it from entering artery walls to form plaque.
2. Much of the cholesterol in the egg is not absorbed by the body because lecithin which is also found in the egg, interferes with its absorption.

Help protect your vision by supplying your bloodstream with a continuous supply of the antioxidants lutein and zeaxanthin. An egg a day can do that. It is however advised to consult your doctor first as it may not be good if you have other ailments at present.
