A new study suggests an overload of calories may increase the risk for memory loss or mild cognitive impairment among people 70 and older.
Researchers from the Mayo Clinic collected information on more than 1,200 dementia-free people.
Those consuming the most calories had more than double the chance of getting mild cognitive impairment.
They were consuming anywhere from about 2,100 to 6,000 calories a day.
Researchers say more studies are needed but suggest cutting calories and maintaining a healthy diet may help prevent memory loss as we age.
