Tim Spector points to Japanese observational studies linking higher mushroom intake with lower dementia risk

What was said

"And there are studies showing that if you can get three portions of mushrooms in your uh diet, you can actually reduce your risk of dementia by about 25%. >> By 25%. >> Yeah. These are long-term observational studies. Uh these this is from Japan, but you know, it convinced me."

While discussing foods for brain health, Prof Tim Spector says long-term observational studies in Japan have found an association between eating around three portions of mushrooms and an estimated 25% lower risk of dementia. He explicitly describes the evidence as observational rather than interventional.
