If you deal with waves of daytime drowsiness, you might be among the estimated 33% of the population suffering from excessive daytime sleepiness. In the largest study of its kind, scientists have uncovered the condition's unique biological fingerprint.

Researchers have successfully tweaked a specialized compound from brown seaweed to unlock its powerful anti-obesity potential. Instead of appetite suppression and fat burning, this molecule reshapes the gut microbiome to fight weight gain naturally.

A massive study of more than 200,000 US adults has revealed that not all potatoes are created equal – as different forms dramatically shift your risk of developing type 2 diabetes. But there's also some good news for lovers of the often-maligned spud.

After reviewing a series of studies involving hundreds of thousands of participants, a team of researchers found three eating plans that significantly reduced the development of type 2 diabetes. All are relatively easy to follow.

In a landmark 14-year study, researchers found that artificially sweetened drinks raise the risk of developing type 2 diabetes by more than a third, higher than those with sugar. It challenges the perception that diet drinks are healthier options.

Your gut bacteria might give away more about you than your accent does. In a new study, scientists used people’s microbiome to predict where they lived, down to the city, with 94% accuracy. It gives new meaning to the phrase "you are what you eat."

Thousands of people who suffer from irritable bowel syndrome swear off a range of food categories to improve their symptoms. One of these categories is gluten, although a new small study shows it might not be the villain many think it is.

A groundbreaking study has revealed that white sugar doesn’t just feed bacteria in the gut – it rewires them. Consuming sugar can trigger physical flips in bacterial DNA, setting off a chain reaction that alters immune responses and gut health.

A world-first clinical trial has revealed that eggs can lower LDL cholesterol, with overall diet saturated fat is taken into account. It rewrites the narrative on dietary cholesterol and offers a science-backed redemption arc to a nutritional villain.

A decade-long global review has confirmed that good heart health, measured by diet, exercise, and other habits, not only protects against heart disease but also supports nearly every organ system, reducing risks of dementia, cancer, and more.

Reducing our intake of a single amino acid called methionine, which we get from the food we eat, could help protect against disease and promote healthy aging. Now, scientists have a better method for studying the effects of this critical compound.

Alternating between a calorie-restricted plan and one high in fat and sugar, resulting in weight gain, is not just down to psychology and behavior. This kind of weight-loss-gain cycle – yo-yo dieting – has a surprising biological driver: The gut.
