It’s time for kids to head back to the classroom and for many of us to return to our regular work schedules. If you’re wondering how to get your brain back into gear, the answer might be no farther away than your refrigerator. Scientists are learning that the right foods, eaten at the right times, can help you concentrate, stay motivated, improve your memory and may even help protect against age-related brain decline.
From carbohydrates and omega-3 fats to blueberries and spinach, research suggests that brain-friendly foods and nutrients are well worth adding to your fall menu.

Here are 7 foods you should eat to boost brain power :
Berries are rich in polyphenols, phytochemicals that protect brain cells by fighting free radical damage, reducing inflammation and removing toxic proteins that accumulate with age. Blueberries and strawberries appear to be most potent in terms of brain health. Try to eat dark purple and dark red fruit every day.
Other polyphenol-rich fruit include acai berries, blackberries, cherries, cranberries, plums, pomegranate seeds, prunes, raspberries and red and purple grapes. When berries are out of season, include frozen and dried berries in your diet.
Research has shown that a walnut-rich diet – equivalent to 1 ounce or 14 walnut halves – can reverse age-related motor and cognitive deficits in aged rats.
Polyphenols in walnuts are thought to protect the brain by fending off free radicals and promoting communication between brain cells. Like berries, walnuts also activate the brain’s house-cleaning process that removes damaged proteins.
A recent report in the journal Neurology found that a daily dose of leafy green vegetables such as kale, arugula, Swiss chard, collard greens, rapini, romaine lettuce and spinach is associated with slower cognitive decline in older adults.
Researchers believe the protective effect of leafy greens is due to vitamin E, an antioxidant that protects brain cells from oxidative damage and inflammation.
Include at least one serving (½ cup of cooked greens or 1 cup of salad greens) in your daily diet. Cooked greens contain more antioxidants than raw.
Include oily fish like salmon, trout, Arctic char, herring and sardines in your diet twice a week to increase your intake of DHA (docosahexaenoic acid), the dominant omega-3 fatty acid in the brain that helps keep the lining of brain cells flexible so memory messages can pass easily between cells.
DHA is also thought to prevent the build-up of beta amyloid, a protein that can interfere with communication between brain cells. Research has also found that increasing DHA intake can improve memory in healthy adults.
If you don’t like fish – or you eat it infrequently – consider taking fish oil in capsule or liquid form. Note, though, that fish liver oil capsules are typically not a good source of omega-3 fatty acids. Long term intake of fish liver oil may lead to toxicity due to high amounts of vitamin A.
Prepare foods with unsaturated fats such as olive, canola, peanut and grapeseed oils. To increase your intake of monounsaturated fat include almonds, cashews, hazelnuts and avocado in your diet. These fats help reduce inflammation, blood clot formation and hardening of the arteries in the brain.
According to research in mice, eating an apple or two each day can sharpen memory. Researchers from the University of Massachusetts Lowell found that a diet enriched with apple juice – comparable to two 8-ounce glasses of apple juice or 2 to 3 apples a day – increased the production of acetylcholine in the brain, resulting in enhanced memory on maze tests. Scientists suspect that antioxidants in apples are responsible for improving cognition and memory.
Low iron stores (e.g. low ferritin in the bloodstream) – even in the absence of full blown anemia – can impair concentration and memory in kids and adults. Iron helps transfer oxygen to brain cells; it’s also used to make neurotransmitters involved in concentration and learning.
Good food sources include red meat, enriched breakfast cereals, whole grain breads, dried fruit beans, legumes, tofu, and nuts. Menstruating females and vegetarians should take a daily multivitamin and mineral supplement to help meet daily iron requirements.
