You need to interpret this properly. Vegetarians usually consume large amounts of refined sugars in the form of candy and other junk food. Vegetarian is not a synonymous of "healthy", but rather someone who just doesen't eat meat. Most vegetarians eat large amounts of refined carbohydrates. Conversely, people who eat the Paleolithic diet eat meat, but they usually avoid refined sugars altogether. They get their carbs from whole grains, vegetables and low sugar fruits like blue berries.
What is confusing about this article is that glycation depends more on protein intake rather than carbohydrate intake. People who age the fastest are those who eat lots of protein and refined carbohydrates. Apes in the wild, who eat lots of fruits but very little meat show very little glycation-related ageing problems like hardening of the arteries and wrinkles. What this tells me is that those vegetarians are ageing because of all the refined carbs they eat and not because they don't eat meat, and that it would be much worse if they did eat meat. The people who eat a Paleolithic diet, conversely, show less glycation because there is very little carbs in their diet to glycate all the protein they eat. They would show even less glycation-related problems if they didn't eat meat at all...

The medical paper states clearly that it is "
Carnosine (beta-alanyl-L-histidine)" "
found exclusively in animal tissues" that appears to suppress aging.
Would carnosine or a carnivorous diet help suppress aging and associated pathologies?AbstractCarnosine (beta-alanyl-L-histidine) is found exclusively in animal tissues. Carnosine has the potential to suppress many of the biochemical changes (e.g., protein oxidation, glycation, AGE formation, and cross-linking) that accompany aging and associated pathologies. Glycation, generation of advanced glycosylation end-products (AGEs), and formation of protein carbonyl groups play important roles in aging, diabetes, its secondary complications, and neurodegenerative conditions. Due to carnosine's antiglycating activity, reactivity toward deleterious carbonyls, zinc- and copper-chelating activity and low toxicity, carnosine and related structures could be effective against age-related protein carbonyl stress. It is suggested that carnivorous diets could be beneficial because of their carnosine content, as the dipeptide has been shown to suppress some diabetic complications in mice. It is also suggested that carnosine's therapeutic potential should be explored with respect to neurodegeneration. Olfactory tissue is normally enriched in carnosine, but olfactory dysfunction is frequently associated with neurodegeneration. Olfactory administration of carnosine could provide a direct route to compromised tissue, avoiding serum carnosinases.
