The secret slimming effect of sweet potato waste.

The secret slimming effect of sweet potato waste.The sweet potato pie you eat during the holidays might not be good for your waistline, but according to a new study, the starchy water left over from cooking the sweet potato could have slimming effects . In the new study, mice on a high fat diet had significantly lower body weight after one month if they were also fed sweet potato peptide, which was produced by enzyme digestion of proteins in the water wasted during processing. This suggests the peptide plays a role in digesting fats, but more research is needed to determine whether this also happens in humans. In the new study, Dr. Koji Ishiguro from National Agriculture and Food Research Organization in Japan and colleagues wanted to find a new way to use this waste, so they investigated the effect of proteins found in the water on digestion in mice. "We throw out huge volumes of wastewater that contains sweet potato proteins -- we hypothesized that these could affect body weight, fat tissue and other factors," explained Dr. Ishiguro. "Finding alternative uses for the sweet potato proteins in wastewater could be good for the environment and industry, and also potentially for health."
