I have been receiving Emails regarding the above and thought this might be a topic that others might wish to comment on.

Carnosine (beta-alanyl-L-histidine) is a dipeptide of the amino acids beta-alanine and histidine and is present at high concentration in muscle and brain tissue.

In vitro studies have shown it to be a potent antioxidant and an inhibitor of glycation. The latter is apparently involved in cataract formation.

Does anyone have information of the incidence of cataracts in meat eaters? Is it possible that meat consumption, meat contains carnosine, may inhibit cataract formation?

While carnosine may be the latest anti ageing agent it comes with a heath warning! Dr. E.K. Schandl is very concerned about this material and has issued a strongly-worded warning.

Anyone with information on cataract incidence related to diet welcome.
