 |  Guest columnistAccording to the 2024 report by the Alzheimer’s Association, nearly 7 million Americans are living with Alzheimer’s disease.A past column two years ago noted a number of studies looking at the positive role of diet with relation to dementia and Alzheimer’s disease. New research suggests intensive diet and lifestyle changes may not only forestall cognitive decline related to Alzheimer’s disease but possibly bring some improvement to those in early stages.According to the study’s authors, the findings showed promising results but cautioned against “overinterpreting” them. They advised that more long-term studies are needed. Read more about the study by accessing a descriptive link at the end of today’s column.Much of today’s column reiterates my prior column which focused primarily on diet. Other lifestyle interventions including being more physically active as well as socialization are also important factors in addressing the issue of dementia and Alzheimer’s disease.Focusing on dietary interventionThe following are some fairly simple ways to “tweak” your diet that might help reduce your Alzheimer’s risk. Ten good foods to consume and five that you might seriously consider avoiding have been recommended by the Mayo Clinic.Have you heard of the Dietary Approaches to Stop Hypertension (DASH) diet for high blood pressure or the Mediterranean diet for heart health? When it comes to protecting your brain health, a hybrid of the two eating styles may be best.Dubbed the “MIND” diet, short for Mediterranean-DASH Intervention for Neurodegenerative Delay, this eating pattern goes big on natural plant-based foods while limiting red meat, saturated fat and sweets. And observational studies suggest the diet can reduce the risk of developing Alzheimer’s disease by up to 53 percent as well as slow cognitive decline and improve verbal memory.Researchers developed the diet by looking at the Mediterranean and DASH diets, then focusing on the foods with the most compelling findings in dementia prevention. Vegetables, especially leafy greens, rose to the top. In general, fruit didn’t, though berries made the list.Then researchers tracked detailed eating logs in an older adult population for an average of 4.5 years to uncover trends among the diets of those who developed dementia versus those who didn’t.Their discovery: Older adults whose diets most closely resembled the pattern laid out in the MIND diet had brains as sharp as people 7.5 years younger. That’s a substantial difference, since delaying dementia by just five years has been suggested to cut the cost and prevalence of the disease in half.Though research is still evolving, evidence is strong that people can reduce their risk by making key lifestyle changes, including participating in regular activity and maintaining good heart health.Lifestyle changesAccording to the Mayo Clinic some key lifestyle changes to support brain health include the following:Avoid smokingControl vascular risk factors, including high blood pressure, high cholesterol and diabetesEat a balanced diet — such as the Mediterranean diet — that’s rich in vegetables, fruits and lean protein, particularly protein sources containing omega-3 fatty acidsBe physically and socially active, including engaging in aerobic exerciseMaintain a healthy weightTake care of your mental healthUse thinking (cognitive) skills, such as memory skillsAvoid head injuryTreat hearing lossLimit alcohol consumptionGrowing evidence indicates that people can reduce their risk of cognitive decline by adopting key lifestyle habits.When possible, combine these habits to achieve maximum benefit for the brain and body. Start now. It’s never too late or too early to incorporate healthy habits.
