Most Americans need more fiber, but going well beyond recommended amounts offers no proven added benefit and can cause uncomfortable side effects. Instead, boost fiber slowly and spread it out over the day, favor whole foods over supplements, and drink plenty of fluids.

Compared with regular yogurt, Greek yogurt delivers double the protein with fewer carbs—but also less calcium. Both types provide probiotics and are generally easier to digest than other dairy products. Look for unflavored versions or those with fewest added sugars, and limit saturated fat.

Breakfast can supply energy and nutrients at the time of day when the body’s metabolism works most efficiently. A nourishing morning meal can include some protein, fiber-rich carbs, and a fruit or vegetable—and it doesn’t have to be typical “breakfast food.”

A 2026 study found that older “super-movers”—adults 80 and older who walk significantly faster than their peers—were substantially less likely than slower walkers to develop cognitive impairment and had larger memory-related brain regions, suggesting that brisk walking speed may signal, or even support, healthier brain aging.

A major study linked high intake of sugary drinks like soda, fruit juices, and sports drinks during teen years and early adulthood with an increased risk of developing high blood pressure in middle age. Replacing sweet drinks with water, milk, or whole fruit may help offset some of those risks.
