5 Brain Boosting Foods—Plus 7 Habits that Strengthen the Brain

Simple diet changes can have a powerful effect on brain health. Research shows that antioxidant-rich foods, moderation, and eating a balanced diet of fruits, vegetables, nuts, healthy fats, and choosing whole grains over refined grains help us retain cognitive function as we age.

Recently, Baycrest Health Services at the University of Toronto published a Brain Health Food Guide. The downloadable guide is based on studies of adults 50 years of age and older who changed their diet and realized a number of benefits.

With simple rules to follow, such as choose color; grill, steam or bake rather than deep fry; and snack smart, eating brain boosting foods has never been easier.

5 Power Foods for the Brain

1. Watermelon

Terry Small, author of the Brain Bulletin has long touted the health benefits of eating watermelon. The succulent fruit has the highest concentration of lycopene (a powerful antioxidant) of any fresh fruit or vegetable. Lycopene benefits the brain by helping to quench the free radicals that contribute to conditions like asthma, atherosclerosis, diabetes, colon cancer and arthritis.

2. Avocados

Including healthy fats in your diet is a simple and effective way to boost brain power. Two-thirds of avocado fat is in the form of monounsaturated fat, the same type of healthy fat that’s in olive oil. Monounsaturated fat is a key feature of the Mediterranean Diet, a healthy eating plan that’s linked to increased longevity. Monounsaturated fat also helps lowers inflammation and bad low-density lipoprotein (LDL) cholesterol while simultaneously increasing healthy high-density lipoprotein (HDL) cholesterol, lowering heart disease risk.

3. Asparagus

Asparagus is an excellent source of the amino acid, asparagine. Asparagine is essential for proper brain function; deficiencies can cause trouble with memory. Known in scientific circles as a non-essential amino acid, asparagine is still critical to our overall health. Non-essential amino acids regulate digestion and absorption of nutrients, help immune function and enable us to rid our bodies of harmful toxins, which can cause inflammation and speed up the aging process.

Pomegranate seeds boost the nutritional impact of any meal and are a great brain food snack. An antioxidant rich food, the ruby kernels are bursting with vitamin C and flavanoids that help keep our brains and blood vessels healthy.

5. Nuts

Nuts are part of the MIND Diet, a well-researched dietary pattern that can help reduce the risk of developing Alzheimer’s disease by up to 35%. The MIND Diet recommends enjoying nuts at least five times a week. Like avocados, nuts are loaded with the same beneficial fat that make olives and their oil sought-after commodities in kitchens around the world.

7 Habits That Help Keep the Mind Sharp

1. Regular exercise

Exercise transforms the brain by stimulating the release of growth factors — chemicals in the brain that influence the health, abundance and survival of new brain cells and the growth of new blood vessels. Exercise can also help improve our mood, sleep patterns and stress level, all of which contribute to cognitive impairment.

For years, experts have been aware that exercise causes a spike in a unique group of chemicals called endorphins, although little has been said about the benefits of exercise on the hippocampus, a small organ located within the brain’s medial temporal lobe.

The hippocampus, a brain area critical for learning and memory, is thought to shrink by as much as 15% in late adulthood, making it a primary target of studies in Alzheimer’s disease. However, a study published in the Proceedings of the National Academy of Sciences is tackling the issue of shrinkage, and highlighting the positive effects exercise can have on hippocampal volume.

Researchers discovered that aerobic exercise increases the size of the anterior hippocampus, leading to improvements in spatial memory. Not only that, they found exercise increased hippocampal volume by 2%, effectively reversing age-related loss in volume by 1-2 years.

2. Meditate

You’ve heard that meditation is great for reducing stress and improving concentration, but it’s even more impressive to see what it can do for our brains as we age.

Multiple studies show that regular meditation can significantly improve attention, memory, verbal fluency and help prevent cognitive decline. During meditation, practitioners experience a period of deep relaxation, called the relaxation response. That relaxation response is thought to reduce stress hormones, change brain waves and release all kinds of healthy benefits throughout your mind and body. Researchers note that when we meditate for as little as 20 minutes a day, there are multiple physiologic changes that benefit our health from head-to-toe. In fact, The National Centers for Complimentary and Integrative Health says that regular meditation can physically change the brain and improve a host of health problems.

3. Spend time with your grandkids

Grandparents who spend quality time with their grandkids stand to gain a wide range of health benefits, including improved cognitive function. An Australian study found that grandmothers who spent one day per week caring for their grandkids displayed the highest cognitive performance of participants studied.

4. Read for 30 minutes each day

Involved reading — the kind invoked by books — improves cognition, which can help protect against age-related illnesses.

5. Keep your brain busy with free crossword puzzles

There’s a lot of information out there about crossword puzzles, and their ability to stimulate the brain. Is it all true? According to research published in the Archives of Neurology, it is. If you’ve been doing crossword puzzles for years, and are looking for a greater challenge, we’ve rounded up online versions that will put your puzzle-playing skills to the test.

6. Participate in the arts

Most older adults associate creativity with their youth and only passively engage in it. However, it may be time to rekindle your artistic energy, even if you only dabbled in painting, dance, theater or storytelling in the past. Research has found that participating in the arts can keep your body healthier, your mind sharper and improve your mood, among other positive health benefits.

Creativity taps into the brain’s own inherent neuroplasticity — its ability to regenerate neural connections that have lain dormant and unused over time. The arts activate parts of the brain that might otherwise gradually decline without use as we age.

7. Volunteer two hours a week

A 2014 review of literature in the Psychological Bulletin showed that when older adults volunteer, they have a 47% lower risk of dementia and cognitive decline than those who don’t volunteer.
