Researchers in Japan are reporting new evidence that the ordinary vinegar — a staple in oil-and-vinegar salad dressings, pickles, and other foods — may live up to its age-old reputation in folk medicine as a health promoter.

Researchers at Purdue University have precisely measured the impact of a high-fat diet on the spread of cancer, finding that excessive dietary fat caused a 300 percent increase in metastasizing tumor cells in laboratory animals.

University of Cincinnati (UC) pathologists have identified a new molecular target that one day may help scientists develop drugs to reduce fat transport to adipocytes (fat cells) in the body and prevent obesity and related disorders, like diabetes.

The enzyme TPPII may contribute to obesity by stimulating the formation of fat cells, suggests a study in EMBO reports this week. The enzyme, TPPII, has previously been linked to making people feel hungry, but Jonathan Graff and colleagues now show that it may be even more deeply involved in causing obesity.

The "health halos" of healthy restaurants often prompt consumers to treat themselves to higher-calorie side dishes, drinks or desserts than when they eat at fast-food restaurants that make no health claims, according to a series of new Cornell studies.

Good news for lovers of fish and chips, Japanese scientists have come up with the perfect recipe to make a crispy batter which is also lower in fat, reports Joanna Harries in Chemistry & Industry, the magazine of the SCI.

New data, generated in mice by Richard Proia and colleagues at the National Institutes of Health, Bethesda, provides a potential reason for early pregnancy loss in humans.

Diets rich in rapidly-digested carbohydrates not only expand waistlines, but may also cause fatty liver, a condition that can lead to liver failure and death, finds a new study in mice. If confirmed in humans, the findings suggest that fatty liver disease – on the upsurge among Americans as a byproduct of the obesity epidemic – may be preventable and possibly treatable through dietary changes. The study appears in the September issue of the journal Obesity.

Microwaves used for zapping instant meals can also be used to determine the fat and salt content of supermarket food, according to research carried out at two Manchester universities.

Scientists have shown that when either lean or obese individuals exercise after eating a high fat meal, their fats are broken down and oxidized in skeletal muscle, making them healthier. These results show for the first time how a high fat diet and exercise stimulate the breakdown of fats and may help design ways to reduce excessive fat in the body.

Scientists have provided new details about how a drug used against heart disease helps to unclog blood vessels from an excess of cholesterol and fats. The results help explain how the drug works and may provide ways to improve similar drugs in the future.

Fat in the stomach may cause vitamin C to promote, rather than prevent, the formation of certain cancer causing chemicals, reveals research published ahead of print in the journal Gut.
