Epigenetics and aging: How are they connected?

Epigenetics is the study of how behavior, the environment, and other factors can trigger chemical changes to DNA or nearby proteins that affect how genes work. Collectively, these changes (known as epigenetic marks) may provide clues about health and longevity.

Nitrates in food and medicine: What's the story?

Nitrates are found in both leafy greens and processed meats. But it’s unclear how much these molecules matter compared with other components of those foods, as dietary nitrate levels have no proven link to heart disease risk.

Oxalates, lectins, and phytates: Do these plant compounds sabotage your health?

“Anti-nutrients” like oxalates, lectins, and phytates are found in leafy greens, beans, and grains. They can slightly reduce absorption of some minerals, but aren’t reasons for most people to avoid these healthy foods. Food preparation and meal planning can help minimize such effects.

MIND diet: Eating for better brain health

The MIND diet combines Mediterranean and DASH diet principles with an added emphasis on brain-healthy foods like leafy greens, whole grains, and fish. Linked in some studies with slower cognitive decline and lower dementia risk, it’s a flexible eating pattern with benefits at any age.

What to eat on the DASH diet

The DASH plan is one of the world’s leading heart-healthy diets. While it limits salt, sugar, saturated fat, and alcohol, it doesn’t have to be bland. With some flavor creativity and changes in shopping and meal planning, it can soon become second nature.

Anti-inflammatory diet: Foods that help reduce chronic inflammation

An anti-inflammatory diet may help rein in chronic inflammation. The eating plan is rich in vegetables, fruit, healthy oils, nuts and seeds, and other foods with anti-inflammatory benefits. What’s not included: refined carbohydrates, red and processed meats, deep-fried foods, and other inflammation-promoting foods.

Are you eating too much fiber?

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.

Harvard study: Early sweet-drink habits tied to high blood pressure later in life

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.

Greek yogurt: Health benefits, protein content, and how to choose the best option

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.

Healthy breakfast ideas to support energy and metabolism

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.”
