People typically can't predict when a stroke will happen, but they can take steps to prevent it. New research suggests that eating plenty of one particular nutrient may help to stop stroke before it strikes.

As people age, exercise is important for maintaining good health, including healthy cholesterol levels. Sometimes, though, medications are needed to cut cholesterol. Unfortunately, treatment with these medications might have an unintended consequence.

According to the so-called "obesity paradox", people who are overweight and have had a stroke have a better chance of surviving than their normal and underweight counterparts. However, some research is starting to debunk this idea.

Although obesity is linked to heart disease, high blood pressure and diabetes, some heavy people seem immune. Those considered “healthy” obese, however, may face health troubles down the line.

Exercise is key to losing weight and keeping that weight off, which is healthy for the heart. But even without weight loss, physical activity may provide quite a bit of benefit to the heart.

Health advocates worldwide have aimed to cut rates of heart disease and the disorders that trigger it. After a half-century of documented progress on that front, Canadian researchers project a change in the root causes of heart disease in that nation.

Even after losing weight, many people end up gaining it back later. Does that time spent at a lower weight still come with health benefits?

Exercise is a crucial part of a healthy lifestyle. But for some people, it appears there is such thing as too much exercise.

Some of the biggest killers worldwide are diseases that can largely be prevented: heart disease, chronic respiratory disease, cancers and diabetes. But it will require some effort.

Heart disease is the leading cause of death in women in high-income countries. It seems that the biggest risk factor for the condition may be a lifestyle habit that can be changed.
