Drinking the water of boiled sweet potato has the following effects: weight loss effect.

Researchers at the National Institute of Agriculture and Food Research in Japan believe that the reason why the water of boiled sweet potatoes can play a role in weight loss is that certain protein enzymes remaining in it can effectively suppress appetite, a substance that has been tested in rats, and which, the researchers say, can be completely replicated in humans.

The researchers tested two groups of fatter rats, and in addition to normal uniform feeding, fed one group sweet potato peptides -- digestive enzymes contained in boiled sweet potato water.

After 28 days of experimentation, the weight and fat tissue of the two groups of rats were re-measured, and it was found that the group of rats fed sweet potato peptide had a significant drop in body weight, and the body's content of leptin, known as the obesity killer, increased significantly, and leptin has long been considered to be a hormone that can increase satiety and reduce appetite. In addition, this group of rats had reduced cholesterol, triglycerides and fat-linked proteins in their bodies.

The researchers said the finding could avoid wasting the water left over from boiling sweet potatoes and also make good use of it for weight loss purposes. Tip: Wash the skins before cooking sweet potatoes, or else you'll be drinking diet sweet potato water mixed with dirt.
