Here’s yet another reason to count your calories. There’s research showing that Zoomers who eat too much are at risk for memory impairment.

People 70 and older who eat between 2,100 and 6,000 calories a day may be at double the risk of these deficits in memory, which can be an early sign of Alzheimer’s disease.

Investigators from the Mayo Clinic collected data on more than 1,200 people, aged 70 to 89. 163 had been diagnosed with mild cognitive impairment.

One-third ate between 600 and 1,525 calories a day, one-third between 1,526 and 2,142 calories a day, and one-third ate between 2,143 and 6,000 calories a day.

Those who ate the most, were more than twice as likely to be diagnosed with the impaired-memory disorder compared to those who ate the least. There was apparently no significant increase in risk for memory problems among those in the middle group.

These findings remained the same after taking into account a history of stroke, diabetes, education and other risk factors for memory loss.

These findings are preliminary but they reinforce the axiom that what’s good for the heart is also good for the brain.
