A new study, conducted at UC Berkeley, indicated that the grapefruit juice could even replace metformin, a drug used for diabetes type 2.
Since the 1930s, consumption of grapefruit is associated with diets, when this method of losing weight was the trend in Hollywood. However, until now there just wasn’t enough precise research that would show how much grapefruit really helps. Now scientists are performing studies on mice to find the link between the consumption of grapefruit and weight gain. Two groups of mice were fed with high fat food, one group was given natural grapefruit juice, while the other group drank only water. The researchers found that the group of mice that drank grapefruit juice gained 18% less weight than the other group. What’s even more interesting, mice who drank grapefruit juice had healthier levels of glucose and insulin in the blood, as well as triacylglycerol fats as compared to the group that drank water.
This fruit helps lower blood sugar, but it is also excellent in preventing weight gain.
Although scientists cannot exactly explain how grapefruit acts, as in the words of Andreas Stal, the leader of this research, the juice of this fruit contains many active components. These findings are irrevocable, because scientists repeated this test many times and each time received the same results.
Finally, one group of mice was given metformin, a drug used to lower blood glucose in type 2 diabetes, and the other group was given naringin, substance that gives grapefruit its bitter taste.
The effects that metformin and grapefruit juice achieved, the lowering of the blood glucose, was the same. “This means that the natural fruit beverage is just as effective in lowering blood glucose as a drug that we buy at the pharmacy.” this was the comment of one of the authors of the study, professor of nutrition and toxicology Joseph Napoli.
Important note: grapefruit juice should not be taken if you use certain drugs, because it can lead to serious health consequences.
