BARTOW, Fla. – As the Florida Grapefruit season ramps up, there may be yet another reason to add the fruit to your grocery list.

A new study, yet to be replicated in humans, suggests drinking a glass of 100% grapefruit juice may help control weight gain and lower blood sugar levels.

Researchers at the University of California, Berkeley found that mice fed a high-fat diet gained 18 percent less weight when they drank grapefruit juice compared to mice that drank water. The grapefruit juice-drinking mice also had a 13 to 17 percent decrease in blood sugar levels and increased insulin sensitivity.

While the findings are positive, researchers want to further study the exact cause behind them.

Previous research identified naringin, a bioactive compound in grapefruit juice, as a key agent in weight loss. However, a group of mice who received naringin had lower blood sugar levels than the control group but had no difference in weight, suggesting another component of grapefruit juice is also beneficial.

And drinking a glass of grapefruit juice may be as beneficial as taking blood sugar-lowering drugs often prescribed for those with type 2 diabetes, the study shows.

“The grapefruit juice lowered blood glucose to the same degree as metformin,” said Joseph Napoli, one of the UC Berkeley researchers who conducted the study, in a University press release. “That means a natural fruit drink lowered glucose levels as effectively as a prescription drug.”

Released on Oct. 8, the study was funded by the California Grapefruit Growers Cooperative. Researchers emphasized the organization had no control or influence over the study or its findings.

The study used slightly sweetened pulp-free grapefruit juice diluted with water. The researchers also added artificial sweeteners to the control group’s water so it would match the calorie content and sweetness of the grapefruit juice.

The mice were fed either a high-fat or low-fat diet for 100 days and their metabolic health was monitored throughout.

The study did not find as big an impact on mice that ate a low-fat diet, though those that drank grapefruit juice had increased insulin sensitivity. Low insulin sensitivity is associated with type 2 diabetes.

“While we’ve long known grapefruit can be part of a healthy diet, the positive findings of this study are encouraging,” said Doug Ackerman, executive director of the Florida Department of Citrus. “We look forward to seeing the results of further research on the health benefits of grapefruit involving human subjects.”

Fresh Florida Grapefruit season typically begins in October and runs through June.

Fruit juice is not linked to obesity, says study http://www.unclematts.com/2017/10/18/orange-juice-and-obesity/ http://www.unclematts.com/2017/10/18/orange-juice-and-obesity/#respond Wed, 18 Oct 2017 18:28:44 +0000 http://unclematts.com/?p=2396 more]]> Findings of the meta-analysis support that 100 percent fruit juice consumption by children is not likely linked to obesity.

BARTOW – A new study provides evidence that consumption of 100 percent fruit juice, such as 100% orange juice, was not associated with weight gain in children over the age of 6 and is not expected to have an appreciable effect on weight gain in those under 6, according to a meta-analysis published in Pediatrics, the official journal of the American Academy of Pediatrics (AAP).

In a commentary accompanying the study, the authors pointed out that past research shows that fruit juice is part of a high-quality diet, counts as a fruit serving, is convenient, and has a longer shelf life compared to whole fruit. They note that the findings of the meta-analysis support that 100 percent fruit juice consumption by children is not likely linked to obesity. While there are gaps in the literature, they conclude that there is no strong evidence that 100 percent fruit juice should be banned for all children, or in programs such as the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC).

Published in March, the study evaluated research related to the consumption of 100 percent fruit juice and changes in body mass index (BMI) among children ages 1 to 18 years. The meta-analysis comprised eight published studies that included over 34,000 individual children and looked at BMI or the BMI z-score, which indicates how weight changes with height over time and whether the changes are out of proportion with each other.

The study showed that for children age 6 and younger, a small amount of weight gain was observed but the amount was not considered to be clinically significant, meaning that the amount would likely not have any practical, genuine, or noticeable effect. The researchers reasoned that children age 2 and younger may be more susceptible to weight gain from 100 percent juice because it represents a larger proportion of their total daily calorie intake compared to older children. The authors also noted that the primary juice consumed by younger children is apple juice, whereas orange juice is favored by older children and has a lower glycemic load than apple juice. Although more research is needed for children age 6 and under, the AAP’s fruit juice intake guideline limits (4 to 6 ounces for children age 1 through 6 and 8 to 12 ounces for older children) are “prudent and should be followed.”

“The banning of fruit juice or failure to allow it in government food programs outside the first year of life is not consistent with the available evidence,” the authors wrote in their commentary.
