Sweet surrender: Added sugar linked to higher heart risk

Diets high in free sugar—which includes sugar added to processed foods and drinks as well as the sugar in syrups, fruit juice, and honey—are linked to an increased risk of cardiovascular disease.

Cut calories or carbohydrates for better heart health?

The carbohydrate-insulin model of obesity considers the biological mechanisms that trigger the body to store too much fat. Eating fast-digesting carbs causes the body to release large amounts of insulin, which causes excess calories to be stored as fat. When fat cells suck up too many calories, there are too few calories for the rest of the body, which causes hunger and overeating. Cutting back on carbohydrates may shift metabolism in ways that promote weight loss without causing excess hunger, while also improving common risk factors for heart disease. The amount of carbohydrate reduction people might consider depends on their specific health parameters.

The humble gallbladder

The gallbladder stores bile from the liver and squeezes it into the small intestine to help digest fats. About 15% of American adults have gallbladder disease, most commonly gallstones. Women are more prone to gallstones because estrogen slows the gallbladder's ability to empty. Serious complications can result from gallbladder disease, including inflammation, infection, and blockages. People can reduce their risk for gallbladder problems by eating more fruits and vegetables, favoring lean proteins, and maintaining a healthy weight.

Preparing for success in the operating room — and beyond

Prehabilitation, or prehab, involves a wide range of steps to take before surgery to maximize recovery afterward. Prehab components include nutritional support, strength and fitness, blood sugar control, medication management, smoking cessation, pain management, and delirium prevention. Research suggests prehab can increase the odds people will heal faster, experience fewer complications, and recover more smoothly over all.

Preventable liver disease is rising: What you eat — and avoid — counts

Fatty liver disease is a condition caused by irritation to the liver, and one specific type is triggered by metabolic risk factors. Following a healthy diet can prevent or possibly even reverse it.

A combination of healthy diets linked with longer life

People who follow a combination of healthy diet plans that share similar traits may have a lower risk of death from cardiovascular disease and cancer.

Eating ultra-processed foods tied to cognitive decline

A 2022 study of 11,000 dementia-free people found that middle-aged participants who ate the most junk food had a faster rate (up to 28%) of cognitive decline, compared with those who ate the least junk food.

DASH diet even better for women's hearts

A 2023 study found that the DASH diet, rich in whole grains, lean protein, nuts, low-fat dairy, and fruits and vegetables, may dramatically lower the risk of heart problems in women and Black adults.

Prediabetes: A window of opportunity

About 96 million Americans have prediabetes, defined by elevated blood sugar levels that are not high enough to qualify as diabetes. Risk factors include overweight or obesity, family history, and inactivity. People with prediabetes may have more infections and frequent urination or blurry vision after big meals. Lifestyle changes such as maintaining a healthy weight, exercising, eating healthy foods, drinking alcohol moderately, and not smoking may prevent prediabetes from progressing to diabetes.

Salt shakedown: How and why you should eat less sodium

In addition to raising blood pressure, too much salt in the diet can have other detrimental effects on the heart, including damaging the inner layer of blood vessels and altering the body's hormonal and inflammatory response. Following the DASH diet, choosing lower-sodium versions of commonly eaten foods, and skipping the saltshaker can help people eat less salt. To boost flavor without salt, options include salt-free herb and spice blends, lemon or lime zest or juice, and flavored vinegars.
