For weight loss, minimally processed diets beat ultra-processed versions

A 2025 study suggested that people can lose more weight by eating minimally processed foods rather than ultra-processed versions, even those typically considered healthy.

How "inflammaging" shapes our health

Inflammaging is chronic, low-grade inflammation throughout the body that occurs with aging. It is believed to accelerate aging and contribute to more than half of all deaths worldwide by driving various age-related diseases such as arthritis, autoimmune conditions, heart disease, cancer, diabetes, and Alzheimer's disease. People can combat inflammaging through healthy lifestyle measures such as exercising, eating healthfully, controlling weight, managing stress, prioritizing sleep, and limiting alcohol and smoking.

Lifestyle counseling may help men eat healthier and reduce their risk for diabetes

Overweight or obese men diagnosed with prediabetes who received counseling on healthy eating habits and online support significantly improved their diets and reduced their risk for developing diabetes, according to a 2025 study.

How to feed your gut

The gut microbiota contains trillions of microbes, including both good and bad bacteria. Good bacteria help digest food and absorb nutrients, regulate appetite, synthesize vitamins, and support the immune system. When the gut microbiota becomes unbalanced because of an increasing number of bad bacteria, problems can arise. Keeping the gut balanced and healthy involves eating more probiotics (foods containing good bacteria) and prebiotics (foods that help existing good bacteria grow).

The salts of the earth

Culinary salts such as Himalayan pink salt, kosher salt, fleur de sel, and flaky sea salt can lend a delightful crunch or flavor to foods. However, they consist largely of sodium chloride, just like table salt, and are no healthier. Consuming too much sodium is tied to increased risks for damage to the heart, kidneys, and brain. Dietitians advise using only a small pinch of a fancy salt, perhaps as a garnish or condiment, to satisfy taste buds without going overboard with the salt shaker.

Skipping breakfast may increase risk for metabolic syndrome

In a 2025 study, skipping breakfast was associated with a 10% increased risk for metabolic syndrome, a disorder defined by having three or more of the following: abdominal obesity, high blood pressure, high blood sugar, high triglycerides, and low HDL cholesterol.

A green-Mediterranean diet may slow brain aging

A 2025 study suggested that following a green-Mediterranean diet - which includes walnuts, green tea, and the aquatic plant Mankai - may be linked with slower brain aging.

Can you take a break from healthy eating?

While a healthy eating plan is crucial for health, bending the rules on occasion probably won't hurt most people. One strategy to try is the 90-10 rule-eating healthy foods 90% of the time and splurging on unhealthy foods 10% of the time. For example, if someone eats three meals a day for a week, for a total of 21 meals, the person would be able to splurge on 10% (about two) of the meals. Dietitians warn that applying the 90-10 rule to every meal can lead to trouble, such as weight gain.

Ultra-processed foods linked to plaque buildup in neck arteries

A diet high in ultra-processed foods is linked to higher burden of fatty plaque in the carotid arteries, according to a 2025 study.

How the body's internal clocks influence heart health

Circadian rhythms, which are hardwired into nearly every cell of the body, regulate the heart and blood vessels. Disruptions to this rhythm-from shift work, poor sleep, or unhealthy habits-can raise the risk of cardiovascular disease. For example, heart attacks are more likely to occur on Mondays than any other day of the week. That's because people tend to stay up later than usual and then sleep in the next day. On Monday morning, when they have to wake up early again for work, the change may cause subtle changes in blood pressure, hormone secretion, and metabolism that raise heart attack risk.
