Abstract

BACKGROUND:

Cardiometabolic risk is the risk of cardiovascular disease (CVD), diabetes, or stroke, which are leading causes of mortality and morbidity worldwide.

OBJECTIVE:

The objective of this study was to determine the potential of low-calorie cranberry juice (LCCJ) to lower cardiometabolic risk.

A new US study shows that as little as two glasses of low-calorie cranberry juice per day can help reduce the risk of type 2 diabetes, heart disease, and stroke. The findings have been published in the “Journal of Nutrition”.

The researchers at the US Department of Agriculture Beltsville, Maryland, enrolled 56 healthy adult volunteers (average 50 years of age) in the study, measuring things like blood pressure, blood sugar levels, blood lipids, as well as C-reactive protein at the outset. They then provided eight weeks’ worth of meals to the participants. While one group received a glass of low-calorie cranberry juice twice daily (around 470 millilitres), the other group drank a placebo beverage with a similar color and flavor.

After eight weeks, the team measured the relevant values again and found that individuals drinking two glasses of low-calorie cranberry juice a day had improved across the board. The change could be associated with a 10 percent lower risk of heart disease and a 15 percent lower risk of stroke.

“These findings suggest that polyphenols help to protect our bodies, and may be adept at keeping a large number of ailments at bay,” said Christina Khoo, one of the study’s authors. “Luckily for us, a rich source of polyphenols is only a glass of cranberry juice away.”

Cranberry juice consumption lowers markers of cardiometabolic risk, including blood pressure and circulating C-reactive protein, triglyceride, and glucose concentrations in adults. J Nutr. 2015 Jun;145(6):1185-93. doi: 10.3945/jn.114.203190. Epub 2015 Apr 22
