Your genes may help explain why you put more sugar in your coffee and on your cereal than other people do. A new study of 1,900 twins and their siblings reports that about 30% of variations in sweet taste perception can be attributed to genetics. People who perceive sweet taste less strongly may add more to satisfy their sweet tooth. Researchers tested four sweeteners, including two non-nutritive options, but found no difference between them, suggesting a single mechanism for sweetness perception regardless of calorie content. The findings were published in Twin Research and Human Genetics.

In New York City, Mayor Bill de Blasio unveiled a plan that would require many chain restaurants to attach a menu saltshaker icon (pictured) to any dish exceeding 2,300 milligrams of sodium-the entire days limit in a single meal. New York would become the first US city to adopt such a rule. Examples of dishes that exceed the 2,300-milligram level include Applebees chicken-fried steak (3,240 milligrams), TGI Fridays Jack Daniels Ribs (3,220 milligrams) and KFCs Famous Bowl (2,350 milligrams). By setting the bar so high, however, some experts noted the cautionary icon would not be required for items that nonetheless contain more than half a days sodium, such as McDonalds bacon and cheese quarter-pounder (1,380 milligrams) or Olive Gardens Florentine Rollatini with Chicken (1,510 milligrams).

A new analysis of data from the Womens Health Initiative (WHI) shows that postmenopausal women who consume the most potassium in their diets are at lower risk of suffering a stroke. The association was strongest in women without hypertension. Although the WHI is an observational study, which cant prove cause and effect, scientists say it provides another reason to boost your potassium intake-especially given that most Americans fall far short of meeting recommended potassium requirements.

The largest study of its kind reports that married people are less likely to suffer from a range of cardiovascular problems, from heart disease to stroke to circulatory issues. In an analysis of data on more than 3.5 million Americans, average age 64, whod undergone health screenings by a private company, married people were 5% less likely to have cardiovascular problems than singles. Compared to married participants, widowed people were at 3% greater risk and divorced people at 5% more risk. The correlation between marital status and cardiovascular health was strongest for those under age 50.

Two new studies suggest that one simple way to reduce your risk of suffering a stroke is to lace up your walking shoes and get moving. In a British study of nearly 3,500 initially healthy men ages 60-80, those who spent time walking were less likely to suffer a stroke, with risk declining as walking time increased. In another new finding, reported at a conference, women who walked or engaged in other moderate-intensity exercise were 20% less likely to suffer a stroke.

Contrary to long-standing concerns about the stimulant effect of caffeine sparking atrial fibrillation, a new analysis concludes that its unlikely habitual caffeine intake from coffee and other dietary sources increases risk. In fact, the pooled analysis found that atrial fibrillation risk fell with increasing caffeine intake.

While eating the traditional fare of Mediterranean countries promotes heart health, consuming fried foods, sweet tea and other typical foods of the Southern United States has the opposite effect, sharply increasing the risk of stroke.
