A healthy diet is believed to play a role in warding off chronic inflammation that can lead to chronic diseases such as diabetes, cardiovascular disease, cancer, and cognitive decline. Six types of foods that may help fight chronic inflammation are berries, fatty fish, leafy greens, nuts, seeds, and tomatoes. These foods are all found in a Mediterranean-style diet, which consists of fruits, vegetables, legumes, whole grains, nuts, seeds, lean proteins, and small amounts of dairy foods and olive oil.

Cellulitis, a skin infection that often occurs on the lower leg, develops when bacteria enter the body through a cut, bite, or other wound. A new study shows key aspects of healing typically occur within 10 days of treatment, but symptoms can linger for some time after that.

The human body has hundreds of lymph nodes, one part of the immune system that helps defend the body against health threats. They aren't usually noticeable, but they are always working to deal with potential health problems.

Who should get COVID vaccine boosters and when will remain in flux for at least another year. This summer, the FDA instructed the vaccine makers to have the next COVID vaccine target the XBB.1.5 Omicron subvariant. The CDC will be issuing specific recommendations by October, but infectious disease experts expect the newer vaccine to provide the most benefit for people over 65 and those younger with chronic conditions.

Removing tonsils in childhood was once routine care for healthy children, but is no longer recommended. Why are some organs and glands — appendix, tonsils, adenoids and more — considered expendable and why do we have them if they're not needed?
