More than 84 million Americans – or, one in three adults – have prediabetes, and 90% of them don’t know they have it, according to the CDC. Don’t let the “pre” fool you - prediabetes is a serious condition that can lead to type 2 diabetes and raise your risk for heart disease and stroke. The good news is that prediabetes can be reversed – but only if you get a diagnosis and make lifestyle changes, like losing weight, eating healthier, and being more active.

Approximately 75 percent of black and men women are likely to develop high blood pressure by the age of 55, compared to 55 percent of white men and 40 percent of white women in the same age range, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.

A lacto-ovo-vegetarian diet, which includes eggs and dairy but excludes meat and fish, and a Mediterranean diet are likely equally effective in reducing the risk of heart disease and stroke, according to new research in the American Heart Association’s (AHA) journal Circulation. Previous separate studies have shown that a Mediterranean diet reduces certain risk factors for cardiovascular disease, as does a vegetarian diet; however, this was the first study to compare effects of the two distinct eating patterns.

Eating spicy foods can help people eat less salt and have lower blood pressure -- potentially reducing their risk of heart attack and stroke -- according to new research in the American Heart Association’s (AHA) journal Hypertension. “Previously, a pilot study found that trace amounts of capsaicin, the chemical that gives chili peppers their pungent smell, enhanced the perception of food being salty,” said senior study author Zhiming Zhu, M.D., professor and director of the Department of Hypertension and Endocrinology at the Third Military Medical University in Chongqing, China. “We wanted to test whether this effect would also reduce salt consumption.”

Stopping long-term, low-dose aspirin therapy may increase your risk of suffering a cardiovascular event, according to new research in the American Heart Association’s journal Circulation.

A healthy lifestyle benefits your brain as much as the rest of your body -- and may lessen the risk of cognitive decline (a loss of the ability to think well) as you age, according to a new advisory from the American Heart Association (AHA) and the American Stroke Association.

Add veggies. Subtract sodium in soups. Use a squirt of lemon. These were among the winners in , the American Heart Association’s (AHA) first-ever #BreakUpWithSalt “hack” contest – an effort to generate tips, tricks or hacks for reducing sodium in processed and restaurant foods.

More than 80 percent of people in urban areas that monitor air pollution are exposed to air quality levels that exceed what the World Health Organization (WHO) deems safe. Poor air quality can lead to the risk of stroke, heart disease, lung cancer and chronic and acute respiratory diseases, including asthma, the WHO said.

Reducing the amount of sodium you put in home-cooked meals may not be sufficient to improve your health if you dine out regularly at restaurants, says a new study, because restaurant foods and commercially processed foods sold in stores contain so much of it.

New York City’s chain restaurants failed last week in their effort to overturn a city rule requiring warning about high-sodium menu items. The New York State Supreme Court Appellate Division upheld the rules set by the city’s Board of Health, finding that it was “well within its authority” to require warnings about menu items that contained more than 2,300 milligrams of sodium, the federally recommended daily allowance.
