Older people who consume a diet very high in calories may be increasing their risk of mild cognitive impairment (MCI), the memory loss and mental-function problems that sometimes precede Alzheimer's disease.
In a new study of more than 1,200 people in their 70s and 80s, Mayo Clinic researchers found that men and women who consumed at least 2,143 calories per day had more than double the odds of having MCI, compared with those who consumed 1,526 calories per day or less.
Preliminary findings from the study are slated to be presented at the annual meeting of the American Academy of Neurology in April. Unlike research published in medical journals, the study has not yet been thoroughly vetted by other experts in the field.
