Studies reveal a surprising connection between obesity and dementia. The reasons are unclear, but researchers suspect that obesity occurs when the food we eat lacks nutrition, leading to the desire to overeat in order to meet the body’s need for vitamins and minerals. So even if you eat a lot, you could still be starving your brain.
Observationally, we can see that by 2015, the number of patients diagnosed with dementia hit almost 45 million, a number that has doubled since 1990. In that same time, national obesity rates in the U.S. went from 11.1% to 30.6%. More studies are needed to unravel the connection, but it is clear that there is one.
