Carbohydrates have become one of the most controversial topics in nutrition. For decades, diet trends have encouraged people to avoid foods such as bread, pasta, rice, and potatoes. Many popular weight-loss programs claim that reducing carbohydrates is the key to losing weight and improving overall health. As a result, low-carb and ketogenic diets have become […]
Heart disease remains one of the leading causes of death around the world. In the United States alone, it is responsible for about one in every four deaths. Although doctors have made great progress in treating heart problems, many people still develop serious conditions that can lead to heart attacks, strokes, and other life-threatening complications. […]
Blood pressure is one of the most important signs doctors use to assess a person’s heart and blood vessel health. Every time the heart beats, it pushes blood through the arteries to deliver oxygen and nutrients throughout the body. Blood pressure measures the force of this blood against the artery walls. When blood pressure remains […]
As people get older, many begin to worry about their heart health, blood sugar levels, blood pressure, and weight gain around the waist. These changes are common with aging, but they can also increase the risk of serious health problems such as heart disease, stroke, and type 2 diabetes. While medications can help manage some […]
Heart failure is one of the most serious and widespread health conditions in the United States and many other countries around the world. Millions of people are living with this disease, and the number continues to increase as populations age and chronic conditions such as high blood pressure, diabetes, and obesity become more common.

Imagine wearing a small patch on your chest that quietly listens to your heart and lungs throughout the day. Instead of waiting for a doctor’s appointment, the device could continuously collect information about your health while you work, walk, eat, sleep, or relax at home. That vision may be closer to reality thanks to a […]
A new study suggests that reproducing a crucial sleep-like brain pattern in awake animals may help preserve memory and learning abilities. What if part of the brain could get some of the benefits of sleep without the rest of the brain ever going offline? A new NIH-funded study suggests that may be possible. Researchers found [...]
EEG studies suggest caffeine can reduce deep, restorative sleep even when sleep duration appears normal. Its effects vary by individual, and relying on caffeine for energy may come at the cost of nighttime recovery. Evening coffee has long been debated. Some people can drink it and fall asleep with no trouble, while others struggle to [...]
Researchers have created a model that follows food beyond traditional calorie calculations, incorporating the role of gut microbes in digestion. Food labels make calorie counts look straightforward. The number listed per serving is calculated from the food’s fat, carbohydrate, and protein content. In reality, the digestive process is much more complex. As food moves through [...]
Scientists found a concerning Alzheimer’s link involving glucosamine, a joint supplement used by millions. A widely used supplement marketed for joint pain relief may be linked to faster progression of Alzheimer’s disease, according to new research from University of Florida scientists. The study found that people with mild cognitive impairment (MCI) who reported taking glucosamine [...]
Every year, influenza, commonly known as the flu, affects millions of people around the world. For many people, the illness causes several days of coughing, sneezing, fever, fatigue, headaches, and muscle aches before they recover. Most healthy adults begin feeling better within a week or two. However, the flu is far more than just a […]
The human heart is one of the hardest-working organs in the body. It never takes a day off and requires a continuous supply of energy to keep beating. To meet these enormous energy demands, heart cells mainly rely on fats as fuel. For decades, researchers have viewed this ability to burn fat as a sign […]
