Harkening back to ancient civilizations, the concept of food as medicine represents one of today’s most cutting-edge approaches to prevention and disease management. Inspired by the intricate connection of mind and body wellness, a small, special group of diets have made their way into the mainstream offering benefits far beyond short-term weight loss. Among them are DASH (Dietary Approaches to Stop Hypertension), a low-sodium diet that encourages consumption of foods rich in nutrients such as potassium and calcium and magnesium; the Mediterranean diet for heart health, emphasizing fish, fruits, and vegetables, with olive oil as the main source of fat; and combining both, the MIND (Mediterranean-DASH Intervention for Neurodegenerative Delay) diet, which shows real promise in helping its adherents preserve cognition and reduce the risk of dementia.
Launched in 2015 by researchers at Rush University Medical Center, the MIND diet encourages selecting foods from categories that include leafy greens and vegetables, legumes, fish and seafood, poultry, nuts and berries, while limiting high fat, high sugar and processed foods. Longitudinal observational studies showed the rewards of shifting to this healthier way of eating, with a 53% reduction in the risk of dementia for seniors who rigorously followed the diet, and somewhat surprisingly, a 35% risk reduction even for those who followed it only moderately well.
“This is my favorite feature,” says Jennifer Ventrelle, MS, RD, lead dietitian for the MIND Diet Intervention to Prevent Alzheimer’s Disease at Rush, “you don’t have to be perfect! It’s not necessary to eat from every preferred category to achieve your goals.”
Although it’s not intended as a reducing diet, Ventrelle says people who follow it naturally lose weight by focusing on the preferred categories of foods. “It’s too difficult for many people to consider banishing all sweets or giving up red meat forever, so we haven’t eliminated these foods but allow them with limited frequency and close attention to portion sizes,” she explains.
Additional research pointed to a host of other benefits associated with eating MINDfully for older adults: slower cognitive decline and progression of Parkinsonian signs in aging, and reduced risk of functional disability, depressive symptoms, metabolic syndrome, cardiovascular disease and all-cause mortality. “The literature continues to grow, with new studies that point to the key role diet plays in preventing cognitive decline,” says Puja Agarwal, PhD, nutritional epidemiologist and assistant professor of internal medicine at Rush.
But it is the gold-standard randomized controlled trial begun several years ago by Rush and Harvard School of Public Health that may ultimately establish a causal relationship between diet and dementia. More than 600 participants at higher risk for Alzheimer’s disease – overweight, suboptimal diets and a history of dementia in the family – were enrolled in the study designed to directly measure whether following the MIND diet versus a low-fat diet can prevent neurodegenerative ills – results are expected by the end of 2022. According to Agarwal, who is fully aware of its significance at a time when more than 6 million people in the U.S. are living with Alzheimer’s disease, a number expected to double in the coming decades. “We don’t have a cure for these diseases, so prevention strategies are essential. We’re hoping for intervention trial results for the effect of MIND diet in protecting the brain to further establish the role of diet in healthy aging.”
What a day of meals on the MIND diet might include*:
BREAKFAST Greek Yogurt Parfait: ½ cup whole grain, high fiber cereal, ½ cup berries, ½ cup low-fat Greek yogurt, 2 tbsps (raw, unsalted) walnuts, almonds or pecans.
LUNCH Whole Wheat Turkey Wrap: 1 tortilla wrap + 3-5 oz turkey breast lunchmeat or carved white meat + 1 slice reduced fat cheese + lettuce, tomato and veggies of choice.
3-Bean Salad: Mixture of kidney beans, black beans, chickpeas, red onions + 1 tbsp extra-virgin olive oil + 1 tsp balsamic vinegar + Italian seasoning mix such as oregano, parsley, basil, etc.
A seasonal bounty of fruits and vegetables is in bloom everywhere from your grocery’s fresh foods section to local farmers’ markets, and in your own backyard garden. The following is advice from experts on how to purchase summer fruits and veggies at its peak, and store them safely, until ready to enjoy.
Berries and Cherries. Look for plump, unblemished fruits with no dark spots or fuzzy white mold; raspberries, blackberries and strawberries should be fragrant. All are shiny when ripe – except for blueberries, which will have a dull matte finish. While most berries can be refrigerated for up to a week, raspberries can start fading more quickly; when that occurs, The Spruce Eats recommends freezing them for use in smoothies and other recipes. To extend their life, do not wash fruit when you unpack your groceries; wait until right before you eat them.
Corn. Choose uncut silks coming out of tightly closed, bright green husks that smell slightly grassy, advises Martha Stewart; and peel back a tad to make sure the kernels look plump and healthy. Refrigerate corn with husks on and use as soon as possible.
Cucumbers and Peppers. Look for firm, shiny vegetables without blemishes, wrinkles or soft spots. According to Have a Plant, cucumbers and peppers can be refrigerated in a plastic bag for up to one week.
Grapes. Choose firm, plump grapes with green healthy stems. They can last up to two weeks when refrigerated. Or try an easy frozen treat: Place on a baking sheet; freeze until firm, and enjoy. Store leftovers in a freezer-safe bag for up to 12 months.
Lettuces. Eliminate those with wilted or broken leaves. Lettuce can be stored for up to four days when refrigerated; darker lettuces tend to last longer than pale, tender varieties. Wash all lettuces just before using.
Melons. Select watermelons without flat sides or dents, and choose ones with a heavy weight for optimal juiciness. Cantaloupe and honeydew melons are best when they have a pale yellow rind and flowery smell at the stem. Harvest to Table recommends storing whole ripe melons in the refrigerator for up to a week to avoid spoiling; cut melons will keep for up to three days.
Plums, Nectarines, Peaches. Opt for vibrant colors, a firm feel, and beautifully fragrant aroma for nectarines and peaches. Store unripe plums, nectarines and peaches in a paper bag until ripe. When ripe, peaches and nectarines can be stored at room temperature for use within a few days; plums can be kept fresh for up to five days in the refrigerator.
Tomatoes. Pick vividly colored, medium-firm tomatoes with smooth, shiny skin. To preserve the freshness and natural flavor of unripe tomatoes, Master Class recommends storing them on a countertop away from direct sunlight. They will last a week on countertops and up to two weeks if stored in the refrigerator.
Zucchini and Summer Squash. Look for smooth-skinned, small to medium size vegetables. Eating Well advises storing zucchini in the crisper drawer of your refrigerator, in either a plastic or paper bag with one end open to ensure good ventilation.
Eating Your Fruits and Veggies May Help Reduce the Risk of Chronic Disease
Fill your plate with a vibrant, colorful array of fruits and vegetables for a naturally delicious way to meet your daily requirement of vitamins, minerals and nutrients. Plant foods contain thousands of natural compounds called phytonutrients, which may have anti-inflammatory benefits that can help reduce the risk of chronic diseases. Every color has a contribution to make – aim for a few different ones each day, and enjoy the entire spectrum.
