An Ayurveda specialist says that eating chocolate leads to early dementing (retarding) is this true?

Has any study been done on this?An Ayurveda specialist says that eating chocolate leads to early dementing (retarding) is this true?
an football manager ,old about 70 years,eats 100 gram every day
in this case it is not true
never heard that....just know chocolate is good and helps ward off depression
I never heard of that. I do know that Ayurveda is based on three specific body types, and some people can be a combination of two or even three body types. Maybe they are saying it can happen to somebody of a certain body type or combination of body types--because Ayurveda teaches that each body type has certain food they should eat and certain foods they should avoid. Ayurveda is a traditional health system invented in India. Some people say chocolate contains the trace element magnesium, and that magnesium puts people in a good mood, but I never heard of any connection between chocolate and dementia--or of any research on that.
