A 2025 study suggests that the nature of ultra-processed foods, not the consumption of extra calories from these foods, is what contributes to their association with excess weight gain and a greater risk for obesity.

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.

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.

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.

The BRAT diet — which stands for bananas, rice, applesauce, and toast — has long been recommended for people coping with diarrhea and vomiting. But adding oatmeal, cooked carrots, skinless chicken, and other bland foods is fine and provides nutrients needed to help people recover. People who have an upset stomach should avoid alcohol, caffeine, dairy products, sugary foods, and foods that are deep-fried, acidic, spicy, or high in fiber. They should also be sure to stay hydrated by drinking water, broth, diluted fruit juice, or weak, decaffeinated tea.

A 2025 study found that eating large amounts of saturated fat raised LDL (andamp;ldquo;bad”) cholesterol levels in the body but dietary cholesterol from eggs did not.

A 2025 study suggests that eating higher amounts of ultra-processed foods such as chips, frozen pizza, cereal, and other prepackaged items high in unhealthy fats, sugar, and sodium is linked to a host of health problems.

Many spices inhibit damaging inflammation that can cause or worsen a variety of chronic diseases. Four beloved holiday spices—cinnamon, cloves, ginger, and turmeric—boast a variety of health benefits, but need to be used liberally to maximize the effects. People can challenge their palates to use more spices all year long by trying new recipes, testing spices in restaurant or ready-made meals, and bringing spice-laden dishes their ancestors once enjoyed to their own tables.

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.

A 2025 study suggests that women who eat more high-quality carbohydrates—which include whole grains, fruits, vegetables, and legumes—in their 40s and 50s are more likely to age healthfully.
