Specifically, a new study revealed a possible connection between drinking whole milk and an increased risk of cognitive decline.

Participants completed food frequency questionnaires, which asked about their intake of dairy products including milk, yogurt, and cheese.

The results didn’t show any negative effects on cognitive performance after consuming low-fat milk, yogurt, cheese, or fermented dairy on a regular basis.

However, higher milk intake — specifically, whole milk — was linked with a greater rate of cognitive decline over a two-year period.
