Healthy gut, healthier aging
Keeping the gut microbiome diverse is good for health and may even be tied to healthier aging. To maintain such diversity, it helps to eat a healthy diet that includes lots of fiber, which gut microbes eat. Also, exercise may be helpful to the gut microbiome, since exercise may change the rate at which material moves through the intestines. Other ways to promote a healthy gut microbiome including getting a dog, which exposes us to more microbes; quitting smoking, which relieves stress on gut microbes; and maybe eating more probiotic-rich foods, which may boost beneficial bacteria in the gut.
Embrace healthy habits for a robust memory
Healthy lifestyle habits may contribute to better brain health and sharper thinking skills. For example, getting at least seven hours of sleep each night gives the brain time to consolidate and store information and also flush out waste—including Alzheimer’s disease–related toxins. Eating a healthy diet helps ward off “mini” strokes that kill brain cells and lead to cognitive decline. Other healthy lifestyle habits that may help cognition include exercising, managing stress, and practicing mindfulness.
