The scientist Alan Hipkiss, from the William Harvey Research Institute in London, reviewed the scientific evidence regarding the question: "Would carnosine or a carnivorous diet help suppress aging and associated pathologies"?
(a) Carnosine (beta-alanyl-L-histidine) is found exclusively in food of animal origin.
(b) Carnosine has the potential to inhibit glycation, generation of advanced glycosylation end-products (AGEs), and formation of protein carbonyl groups which play important roles in causing aging, diabetes, its secondary complications, and neurodegenerative conditions.
(c) Carnivorous diets could be beneficial because of their carnosine content, as carnosine has been shown to suppress some diabetic complications.
(d) Carnosine may help to prevent neurodegeneration.
This review finds that carnosine or a carnivorous diet can help to suppress aging and associated pathologies.
The best food sources of carnosine include beef, poultry and pork. Carnosine is not in any foods of plant origin.
