How a fiber-rich diet promotes heart health

Fiber-rich diets may lower the risk of heart attack and stroke, in part by decreasing inflammation. This benefit appears to be facilitated by the breakdown of prebiotic fiber in the gut microbiome to create short-chain fatty acids. These compounds circulate through the bloodstream and interact with specific receptors on cells that quell inflammation. Short-chain fatty acids may also play a role in keeping blood sugar, blood pressure, and cholesterol levels in check, as well as helping to prevent harmful blood clotting.

You don't say? Can your joints wear out?

Joints do not wear out from overuse. Osteoarthritis, the most common type of arthritis, occurs when the smooth cartilage that lines the joint deteriorates. This might occur because of an injury, age, family history, obesity, or a disease that causes joint inflammation.

Is sugar unhealthy?

Sugar is a carbohydrate that provides the body with energy and has an important role in nutrition. It is found in many healthy whole foods, but it is also abundant in unhealthy processed foods. The problem many people have with sugar is that they consume too much of the refined kind added to many processed food products, and not enough of the natural kind in fruits, vegetables, and grains.

The little things that can improve your health

In addition to major healthy lifestyle habits, such as exercising and eating a healthy diet, it's important to practice lots of little healthy habits throughout the day. Some should be observed every 30 minutes, such as taking a quick activity break and drinking a little water. Other habits, such as having a healthy snack or using eye drops, can be done every few hours. And some healthy habits help if practiced even just once a day, such as learning something new, chatting with someone outside of the household, or meditating.

Why don't more people know CPR?

Fewer than half of people who experience cardiac arrest outside of a hospital receive CPR from someone nearby. Shorter, more accessible training and help from technology may encourage more people to learn and administer this lifesaving technique. Another potential barrier to performing CPR is not recognizing the symptoms of cardiac arrest. Common mistakes include pressing down on the stomach instead of the center of the chest, not compressing the chest deeply enough, or giving compressions that are either too fast or too slow.

Preventing C. diff in and out of the hospital

The bacteria C. diff is responsible for half a million infections each year in the US. Many infections happen when people are hospitalized, but a recent report indicated that people can be infected without ever being hospitalized.

Can a vegan diet treat rheumatoid arthritis?

A recent study suggested a vegan diet is an effective treatment for rheumatoid arthritis, and its lead author also said that people should try changing their eating patterns before turning to medication. But there is no evidence that changes in diet can prevent joint damage that occurs in rheumatoid arthritis.

Can an implanted tongue-stimulating device curb your sleep apnea?

A mask-free, implanted device for sleep apnea that works by stimulating the tongue was approved by the FDA in 2014 as a second-choice treatment for people who are unable to tolerate a positive airway pressure machine.

Poliovirus in wastewater: Should we be concerned?

Thanks to vaccination, the US has been polio-free since 1979, and the spread of this disease has been interrupted in most countries. But worldwide eradication of polio has been elusive, and traces of the virus were recently found in wastewater in London.

Eating less meat may lower overall cancer risk

A 2022 study suggests that eating meat (including poultry) fewer than five times a week may protect people from cancer. Consuming only fish and no meat or following a vegetarian or vegan diet may offer even greater protection.
