It's a tea (well, sort of) and it might just be the best new drink for weight loss for people concerned about slimming down in the new year.
Forget about green tea; we've all heard that one before. A team of researchers from Japan is suggesting that drinking the wastewater produced upon boiling sweet potatoes--yes, you read that right--can help lower fat levels and suppress your need to snack throughout the day.
Since in Japan alone, 15 percent of sweet potato is used for starch-derived products and processed foods, huge amounts of wastewater then ends up in rivers and oceans. To avoid the environmental repercussions of this waste, the scientists set out to measure the health effects of drinking the water produced after boiling the potatoes, which are rich in a range of B-vitamins.
The team fed three groups of mice high-fat diets, and one group’s regime included a high concentration of the sweet potato peptide protein (SPP), while another was given a lower dosage. After a month, the researchers collated the rodents' data, taking into account their liver mass, fatty tissue, fat cholesterol levels and triglyceride levels and measuring levels of leptin, which controls hunger, and adiponectin, which regulates metabolic syndrome.
The shocking results? Mice who had been given SPP had a significantly lower body weight and liver mass, as well as lower cholesterol and triglycerides. And as the SPP groups also had higher levels of the hunger and lipid-controlling hormones, the team was able to speculate that SPP had the ability to act as an appetite suppressant.
"We were surprised that SPP reduced the levels of fat molecules in the mice and that it appears to be involved controlling appetite suppression molecules," said Dr. Koji Ishiguro, who worked on the study. "These results are very promising."
Sounds like it!
