Tim Spector links poor diet and type 2 diabetes to dementia risk

What was said

"We know that type two diabetes is associated with a three-fold increase in dementia and we know that poor diets are associated with a similar increase. So whether or not you develop type 2 diabetes or not, it's the diet that's the problem."

Prof Tim Spector says epidemiological studies associate type 2 diabetes with about a three-fold higher dementia risk, and poor diets with a similar increase. He argues diet is a major reversible risk factor, while adding that evidence for reversing severe Alzheimer’s is less convincing than for early decline and prevention.
