The researchers concluded that Consumption of high red and processed meat and a low-fiber, medium-glycemic index/glycemic load diet in young individuals without T2DM significantly increased plasma CEL concentrations, but not plasma CML, and MG-H1 concentrations, compared with consumption of a diet high in dairy, whole grains, nuts and legumes and low in GI/glycemic load.
UniSA researcher Dr Permal Deo says the research provides important dietary insights for people at risk of such degenerative diseases.
"When red meat is seared at high temperatures, such as grilling, roasting or frying, it creates compounds called advanced glycation end products - or AGEs ¬- which when consumed, can accumulate in your body and interfere with normal cell functions," Dr Deo says.
"Consumption of high-AGE foods can increase our total daily AGE intake by 25 per cent, with higher levels contributing to vascular and myocardial stiffening, inflammation and oxidative stress - all signs of degenerative disease."
The study tested the impacts of two diets - one high in red meat and processed grains and the other high in whole grains dairy, nuts and legumes, and white meat using steaming, boiling, stewing and poaching cooking methods.
It found that the diet high in red meat significantly increased AGE levels in blood suggesting it may contribute to disease progression
Largely preventable, cardiovascular disease (CVD) is the number one cause of death globally. In Australia, it represents one in five of all deaths.
Co-researcher UniSA's Professor Peter Clifton says while there are still questions about how dietary AGEs are linked to chronic disease, this research shows that eating red meat will alter AGE levels.
"The message is pretty clear: if we want to reduce heart disease risk, we need to cut back on how much red meat we eat or be more considered about how we cook it.
"Frying, grilling and searing may be the preferred cooking methods of top chefs, but this might not be the best choice for people looking to cut their risk of disease.
"If you want to reduce your risk of excess AGEs, then slow cooked meals could be a better option for long-term health."
