We’re constantly told: Eat healthy whole foods, not vitamins. But research reveals some of those foods have been delivering less nutrition for decades. Yet we’re still discouraged from doing one simple thing that could help.

Epigenetic age presents a more accurate picture of how well your body’s cells and tissues are functioning. That makes it a more precise measure of age. And unlike the age indicated on your driver’s license, you can reverse it…

Most of us think aging moves in only one direction. But after just four weeks of eating differently, older adults showed signs of a younger biological age. And get this: the diet with the clearest results may challenge what you’ve heard about eating for longevity.

What if your metabolism is waiting for a signal your usual workout isn’t sending? Researchers found a striking difference in how the body responds to exercise—and logging more minutes wasn’t the deciding factor.

Stress doesn’t always end when your day does. Its biological effects can reach areas of the brain involved in memory and thinking. And, oddly enough, show up in our saliva to offer an overlooked clue about brain aging.

Protein is everywhere right now — but researchers are asking whether constantly adding more is really the best strategy for healthy aging. A major review suggests that, for some people, the answer may lie in doing the opposite.

Poor sleep and memory changes often show up together. New research suggests one familiar vitamin may matter more than expected during this early window of cognitive change — but the dose linked to the strongest result may surprise you.

Always tired or struggling to stay motivated? That can sound an awful lot like chronic fatigue. New research points to a blood marker that may help explain why — and it’s one already linked to heart and brain health.

Vitamin C was largely written off as a cancer treatment decades ago. Now scientists are revisiting the story — and one overlooked difference may explain why the question never really went away.

You may buy “clean” shampoo, fragrance-free lotion or non-toxic cleaners to limit what comes into your body and your home. But lab testing of everyday products found far more chemicals than their labels revealed. Here’s what that means for making smarter choices.

None of us want to add one more medication to a list that may already be long. So when a natural remedy, especially one with history, has the clout to improve cholesterol, that’s just too good to keep quiet about.

Belly fat becomes increasingly common as we age. But researchers have discovered something that could make it far more dangerous: having too little of one important vitamin at the same time.
