Are you eating your way to Dementia?

More than half of the calories consumed by Americans are in this high risk food group: ultra processed foods. Eating just 400 calories a day can increase your dementia risk by over 20%.

10,000 subjects were followed for 10 years and asked about their eating habits. The subjects also took cognitive tests up to three times a year, including memory tests and word recognition tests, to monitor their mental abilities such as learning, thinking, reasoning, remembering, problem-solving, decision-making and attention.

Those who ate 20% or more of their daily calories from ultra-processed foods had a 28% faster rate of cognitive decline, and a 25% faster rate of executive function decline, compared to the subjects in the study who ate the least amount of processed foods. In other words, someone following a 2,000-calorie-a-day diet who consumed 400 calories from frozen tray meals, processed meats (hotdogs, lunch meat), white bagged bread, snack cakes, breakfast cereals/bars and sodas each day saw a faster rate of cognitive decline.

There is an important point in the study: If the overall quality of a subject’s diet is otherwise very high (meaning they ate a lot of unprocessed whole foods like fruits and vegetables, whole grains and lean proteins), then the association between ultra-processed foods and dementia disappeared. So the good news is, you can counter consuming ultra-processed foods by eating whole foods like fresh or frozen produce, lean meats and proteins.

“Limiting ultra-processed food consumption, particularly in middle-aged adults, may be an efficient form to prevent cognitive decline,” researchers wrote in their findings published in JAMA Neurology December 2022.
