EXERCISE PROTECTS THE DECLINING BRAIN
Samantha Rideout

It’s not unusual, and nothing to worry about, for some cognitive decline to occur as you age. But if you have more difficulty with judgment, language or memory than is expected for your age, a doctor may diagnose you with mild cognitive impairment (MCI). This condition raises your risk of progressing to dementia. However, in a Korean study of nearly a quarter-million people with MCI, participants who exercised more than once a week were 18 per cent less likely to develop Alzheimer’s disease. Physical activity may protect us by increasing blood flow to the brain or by aiding the production of the molecules that help neurons to grow.

For Most People, the Benefits of Multivitamins Are an Illusion

Millions of us take a multivitamin every day—and feel like we’re getting results. In a Harvard-led investigation, people who used these supplements rated their overall health, on average, 30 per cent higher than non-users’ own self-assessments. It turns out, though, that both groups actually had comparable levels of well-being, both physically and mentally. It’s possible that people with a more positive outlook are more attracted to multivitamins, or that taking them encourages you to see yourself as the picture of health. Either way, they’re probably not worth your money unless you have a restrictive diet (e.g., vegan or glutenfree), a pregnancy or a medical issue that specifically calls for supplements.

IN SEASON Chickpeas (GARBANZO BEANS)

Chickpeas appear in early recordings in Turkey well over 5000 years ago. India produces the most chickpeas worldwide but they are grown in more than 50 countries. An excellent source of carbohydrates, protein, fiber, B vitamins, and some minerals, they are a nutritious staple of many diets. The name chickpea comes from the Latin word cancer, referring to the plant family of legumes, Fabaceae. It is also known by its popular Spanish-derived name, the garbanzo bean. Kidney beans, black beans, lima beans, and peanuts are other familiar foods found in this legume family.
