New discoveries are made every day. The field of health research is no different. It can be difficult to follow what scientists discovered recently. Here we summarized the latest news on health.

1. People who survived heart attack are at risk for diabetes or prediabetes, according to Harvard researchers. A study of 8,300 Italians who had survived a heart attack revealed that after 3.5 years, almost two-thirds of them or 62% developed diabetes or prediabetes.

2. First, scientists told us that high levels of vitamin E are no so good at preventing a heart attack. Late, researchers at Vanderbilt University Medical Center said that failure of vitamin E to prevent heart attacks is because of underdosing.

3. Too much salt in your diet can lead to high blood pressure and increased risk of heart attack or stroke. The average man consumes 4,000 to 6,000 milligrams of salt each day. The American medical institutions recommend a limit of 1,500 mg to 2,400 mg a day.

4. A recent study published in the American Journal of Clinical Nutrition revealed that consuming two to three daily cups of caffeinated drinks, including coffee, can reduce your risk of dying from heart disease by 31 percent.
