New Research Suggests Drinking Vegetable Juice Daily May Help People with Metabolic Syndrome Lose Weight

(BUSINESS WIRE)--Drinking at least one glass of low sodium vegetable juice daily may help overweight people with metabolic syndrome achieve better weight loss results. A study, conducted at the Baylor College of Medicine and presented at this week’s Experimental Biology Meeting, found that participants who drank at least 8-ounces of low sodium vegetable juice as part of a calorie-controlled DASH diet lost four pounds over 12 weeks, while those who followed the same diet but drank no juice lost one pound.1

Metabolic syndrome is defined by a cluster of risk factors including excess body fat in the midsection, high blood pressure, high blood sugar and abnormal blood lipids. If left uncontrolled, metabolic syndrome increases risk for chronic diseases, such as heart disease, stroke or diabetes. An estimated 47 million Americans have some combination of these risk factors and are often overweight or obese as well.

Participants in the study were primarily African-American and Hispanic adults, populations that typically have a higher incidence of metabolic syndrome. Each group followed a DASH (Dietary Approaches to Stop Hypertension) diet that emphasized eating lean meat, lower fat dairy, whole grains, vegetables and fruit daily and keeping saturated fat, total fat, cholesterol and sodium in check. Two of the groups were given Low Sodium V8® 100% vegetable juice and instructed to drink 1 or 2 cups every day for 12 weeks, while the third group was not given any vegetable juice.

The key study findings include:

* On average, the vegetable juice drinkers lost four pounds over 12 weeks, while those who did not drink juice lost one pound
* Vegetable juice drinkers were more likely to meet the daily government recommendations of 3-5 servings of vegetables (1 ½ to 2 ½ cups)3

* Seven out of 10 American adults fall short of recommendations4

* Vegetable juice drinkers significantly increased their intake of vitamin C and potassium, while decreasing their overall carbohydrate intake

“Diet and body weight are key modifiable factors in changing the course of metabolic syndrome,” said John Foreyt, PhD, study author and Director, Behavioral Medicine Research Center, Baylor College of Medicine. “What this study shows is that by taking simple, proactive steps such as drinking low sodium vegetable juice while watching calorie intake, people can begin to control their weight, which helps reduce the risk of long-term health implications.”

Study Details

The study, conducted by the Baylor College of Medicine, was a randomized, controlled trial (RCT) that lasted 12 weeks and enrolled 81 adults with metabolic syndrome (59 female, 22 male; 57% African American, 22.8% Mexican American, 3.7% Other and 16.5% White). Participants were given Low Sodium V8 100% vegetable juice which has 140 mg sodium and 820 mg potassium per serving. Research funding was provided in part by Campbell Soup Company, and supported by resources from Baylor College of Medicine and the University of California-Davis.
