If the results hold up, they could point the way toward new treatments.
Cooking meat may be a risk factor for dementia and diabetes, according to new research. When meat is heated, it can produce advanced glycation end products (AGEs), which form when protein or fat reacts with sugar. The research found a link between high blood levels of these and cognitive decline in adults over 60, as well as reduced insulin sensitivity (a precursor to type 2 diabetes), the BBC reported. Mice fed a diet high in AGEs also accumulated a defective protein in their brains and performed worse on mental and physical tests.
The idea is that a diet rich in AGEs can change the brain's chemistry, at least in mice, according to the BBC:
It leads to a build-up of defective beta amyloid protein--a hallmark of Alzheimer's disease. The mice eating a low-AGEs diet were able to prevent the production of damaged amyloid. The mice performed less well in physical and thinking tasks after their AGEs-rich diet.
The mice fed a high-AGE diet went on to develop symptoms similar to Alzheimer’s, such as problems with their balance and coordination, the United Kingdom's National Health Service pointed out.
