Preventing Alzheimer’s Disease (Part 2 of Series)

Alzheimer’s is a complex disease with multiple risk factors. Last month, we included an article about the first of seven pillars for a brain-healthy lifestyle that is within your control: Regular Exercise.

Experts now believe that the risk of Alzheimer’s is not limited to old age, but in fact can start in the brain long before symptoms are detected, often in middle age. That means that it’s never too early to start taking care of your brain health. The more you strengthen each of the seven pillars in your daily life, the longer—and stronger—your brain will stay working and the more likely you’ll be able to reduce your risk of developing Alzheimer’s or another dementia.

This month’s article will focus on the Second and Third Pillars: Social Engagement and a Healthy Diet.

Pillar #2: Social engagement
Human beings are highly social creatures. We don’t thrive in isolation, and neither do our brains. Staying socially engaged may even protect against Alzheimer’s disease and dementia in later life, so make developing and maintaining a strong network of friends a priority.

You don’t need to be a social butterfly or the life of the party, but you do need to regularly connect face-to-face with someone who cares about you and makes you feel heard. While many of us become more isolated as we get older, it’s never too late to meet others and develop new friendships:
• Volunteer
• Join a club or social group
• Visit your local community center or senior center
• Take group classes (such as at the gym or a community college)
• Get to know your neighbors
• Make a weekly date with friends
• Get out (go to the park, museums, and other public places)

Pillar #3: Healthy diet
In Alzheimer’s disease, inflammation and insulin resistance injure neurons and inhibit communication between brain cells. Alzheimer’s is sometimes described as “diabetes of the brain,” and a growing body of research suggests a strong link between metabolic disorders and the signal processing systems. By adjusting your eating habits, however, you can help reduce inflammation and protect your brain.
• Manage your weight. Extra pounds are a risk factor for Alzheimer’s disease and other types of dementia. A major study found that people who were overweight in midlife were twice as likely to develop Alzheimer’s down the line, and those who were obese had three times the risk. Losing weight can go a long way to protecting your brain.
• Cut down on sugar. Sugary foods and refined carbs such as white flour, white rice, and pasta can lead to dramatic spikes in blood sugar which inflame your brain. Watch out for hidden sugar in all kinds of packaged foods from cereals and bread to pasta sauce and low or no-fat products.
• Enjoy a Mediterranean diet. Several epidemiological studies show that eating a Mediterranean diet dramatically reduces the risk of cognitive impairment and Alzheimer’s disease. That means plenty of vegetables, beans, whole grains, fish and olive oil—and limited processed food.
• Get plenty of omega-3 fats. Evidence suggests that the DHA found in these healthy fats may help prevent Alzheimer’s disease and dementia by reducing beta-amyloid plaques. Food sources include cold-water fish such as salmon, tuna, trout, mackerel, seaweed, and sardines. You can also supplement with fish oil.
• Stock up on fruit and vegetables. When it comes to fruits and vegetables, the more the better. Eat up across the color spectrum to maximize protective antioxidants and vitamins, including green leafy vegetables, berries, and cruciferous vegetables such as broccoli.
• Cook at home often. By cooking at home, you can ensure that you’re eating fresh, wholesome meals that are high in brain-healthy nutrients and low in sugar, salt, unhealthy fat, and additives.
• Drink only in moderation. While there appear to be brain benefits in consuming red wine in moderation, heavy alcohol consumption can dramatically raise the risk of Alzheimer’s and accelerate brain aging.
