More Evidence Linking Sugared Drinks to Diabetes

A new study uncovers some potentially important new details about the association between sugared drinks and diabetes. In a paper published in Diabetologia, researchers in the U.K. report on more than 10 years of followup of more than 25,000 adults. During the course of the study 847 participants went on to develop diabetes. Instead of relying on a […]

Weight-Loss Programs: Slim Evidence and Thin Results

A new study concludes that some weight-loss programs may be slightly better than other programs but that in the long run none of the programs have been able to show a substantial weight loss over a sustained period. For even the best programs, an editorialist writes, “weight loss is modest and likely below patients’ expectations.” In […]

How Do You Like Them Apples?

An apple a day does not appear to keep the doctor away but, a new study semi-seriously suggests, it may keep the pharmacist away. Although apples have long been considered a healthy snack, whether eating apples actually reduces healthcare use has not been assessed until now. In a paper published in JAMA Internal Medicine researchers examined […]

Study Tests Very Simple High-Fiber Diet

Diets notoriously fail to help people lose a lot of weight. One problem is that most diets include a broad range of restrictions and guidelines that many people find difficult to follow. Another problem is that negative recommendations may have unintended consequences, such as low-fat recommendations leading to increased consumption of refined carbohydrates. Now a […]

No Advantage for Low-Glycemic-Index Diet

In recent years the glycemic index (GI), a measure of a carbohydrate’s impact on blood sugar, has assumed a major role in discussions about diets and nutrition. Now a study suggests that by itself, within the context of an otherwise healthy diet, GI may not be an important factor in improving cardiovascular risk. In a paper […]

Focus on Getting Rid of Sugar, Not Salt, Say Authors

Too much negative attention has been focused on salt and not enough on sugar, write two authors in Open Heart. Reviewing the extensive literature on salt and sugar, they write that the adverse effects of salt are less than the adverse effects of sugar. The evidence supporting efforts to reduce salt in the diet is […]

Dietary Fiber After MI Linked to Improved Survival

Consuming more dietary fiber after myocardial infarction is associated with a reduced risk for death. In a report published in BMJ, researchers analyzed long-term data about diet and other risk factors from more than 4000 healthcare professionals who had an MI. Nine years after the MI, people who were in the highest quintile of fiber consumption had a […]

Studies Provide Little Support for Guidelines on Dietary Fats and Supplements

The precise cardiovascular effect of dietary fats and supplements has been the subject of heated controversy. Although there is no strong supporting evidence from clinical trials, current guidelines tend to discourage or minimize the role of saturated fats and trans fats and to encourage the intake of omega-3 polyunsaturated fatty acids. Two new studies published today help clarify […]

Meta-Analysis Links Vegetarian Diet and Lower Blood Pressure

A new meta-analysis provides the strongest evidence yet that a vegetarian diet is strongly associated with lower blood pressure. Although various health benefits of a vegetarian diet have often been proposed, a rigorous examination of the effect on blood pressure has not been previously performed. In a paper published in JAMA Internal Medicine, Japanese researchers analyzed data from […]
