The dried version of grapes may be a good addition to one’s diet, according to research that suggests it may be linked to lower obesity rates.

Researchers using data from the National Health and Nutrition Examination Survey found that when people ate at least one-eighth of a cup of dried fruit, such as raisins, they were less likely to be obese, notably at the waistline.

"The results of this analysis showed a lower prevalence of obesity, specifically abdominal obesity, among adults who consumed dried fruit as compared to those who did not eat dried fruit," said lead researcher Debra Keast.

Grapes, dried or fresh, have also been linked to improved heart conditions by some studies.

A grape antioxidant called polyphenol may help to decrease hardening of the arteries, as well as lowering blood pressure according to Australian researchers from Commonwealth Scientific and Industrial Research Organization.

The fruit may also have a place in improving digestive function as Clemson University researchers found that it helped to limit a bacteria that can cause some ulcers and gastritis.
