Health warning for high-heat meat
Tuesday, 08 September, 2020
Culinary experts recommend high-heat caramelisation to boost the flavour of meat, but results from a recent study reveal that it could be bad for our health.
The (UniSA) study 鈥� conducted in partnership with 鈥� found that consuming red and processed meat increased a protein compound that may increase the risk of heart disease, stroke and complications in diabetes.
UniSA researcher Dr Permal Deo said the research provides important dietary insights for people at risk of such degenerative diseases.
鈥淲hen red meat is seared at high temperatures, such as grilling, roasting or frying, it creates compounds called advanced glycation end products 鈥� or AGEs 鈥� which, when consumed, can accumulate in your body and interfere with normal cell functions,鈥� Dr Deo explained.
鈥淐onsumption of high-AGE foods can increase our total daily AGE intake by 25%, with higher levels contributing to vascular and myocardial stiffening, inflammation and oxidative stress 鈥� all signs of degenerative disease.鈥�
With results published in , the study tested two diets: one high in red meat and processed grains; the other high in whole grains, dairy, nuts, legumes and white meat using steaming, boiling, stewing and poaching cooking methods.
The diet high in red meat significantly increased AGE levels in blood, suggesting it may contribute to disease progression.
UniSA co-researcher Professor Peter Clifton said while there are still questions about how dietary AGEs are linked to chronic disease, the research shows that eating red meat will alter AGE levels.
鈥淭he 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.
鈥淔rying, 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.
鈥淚f you want to reduce your risk of excess AGEs, then slow-cooked meals could be a better option for long-term health.鈥�
