You probably know an older person who is as mentally sharp as anyone despite being in their 80s or 90s. However, you might also know a much younger person who cannot recall events and whose memory has taken a nosedive. Sometimes it's not the genes, but our lifestyles, that cause this difference, but there are some things you can do to give yourself a better chance at keeping your mind agile.
Scientists have observed that neurons in the brain seem to need docosahexaenoic acid (DHA) to function normally. DHA is one of the Omega 3 fatty acids, mostly found in fish. They are also found in eggs and seeds like chia seeds, pumpkin seeds and walnuts. Other foods like blueberries are also rich in gallic acid, which helps prevent degeneration and stress. Avocadoes are also rich in antioxidants, especially Vitamins E and C, that help prevent blood clots in the brain, thus helping to prevent stroke and improve brain function.
