It is only known that grapes and of course, wine, resveratrol have composed powerful antioxidant qualities which are a great ally in the fight against cancer and cardiovascular disease.
However, the fruit of the vine has another powerful compound, which is much less known and is attracting the attention of scientists.
The molecule in question is the piceatannol and several preliminary investigations have indicated that you have the ability to induce apoptosis, cell death in cancer tissues.
However, a new study has revealed another virtue of piceatannol that could make a weapon against obesity.
The recent findings of Kee-Hong Kim and Jung Yeon Kwon, University of Purdue, Indiana, USA. UU., Demonstrate that the compound does inhibit the development of new adipocytes, the cells stored in body fat.
This is an interesting finding since it is possible that inhibiting the formation of new adipose cells, also can prevent accumulation of new body fat.
The study, whose results were published in the latest edition of the Journal of Biological Chemistry , was to evaluate the effect of piceatannol in cultured fat cells.
To form a new fat cell, you must carry out a process that lasts about 10 days time that immature fat cells, called preadipositos, must pass through several stages to reach full maturation.
In the lab, Kim and Kwon showed that piceatannol blocks the effect of the hormone insulin on preadipositos. It turns out that insulin is required to activate within the preadiposito the ripening process, so by blocking its influence on the growth slows down and never gets to become a fat cell.
Although the findings are promising, much remains to be done to find out if the compound present in grapes, white tea and blueberries, can actually be used to help prevent obesity.
Scientists will focus their efforts on designing studies in animal models and achieve a more stable synthesis of this compound.
For now, at least we have more good reason to toast with a glass of wine.
