“Also, there is a huge amount of evidence showing that the Mediterranean diet is the best diet we’ve got so far for brain and heart,” she added. “That includes a lot of whole grains. We’re going to need a lot more research if the ketogenic diet is going to be widely recommended as an alternative to that approach as a prevention against dementia.

that approach 表示Mediterranean diet，由于 Mediterranean diet 有哪些用途是a prevention against dementia。
