Sweet Potatoes Have the Strongest Cholesterol-Lowering Effect
Japanese scientists discovered that six plants—sweet potatoes, soybeans, ginger sprouts, celery, chrysanthemum, and angelica—can inhibit cholesterol production, with sweet potatoes showing the most significant effect.
This conclusion comes from analyzing 130 types of vegetables, fruits, and flowers by scientists from Tokyo University and three other research institutions. Experiments confirmed that sweet potatoes inhibit cholesterol production ten times more effectively than other plants. Scientists also found that the active ingredient is a substance combining lipids and carbohydrates in sweet potatoes. It inhibits the activity of a key enzyme involved in the final stage of cholesterol synthesis.
The *Japan Agricultural News* recently reported this finding, citing Professor Yukihiro Kawai of the National Institute of Food and Drug Safety: “This research is valuable because it reveals that sweet potatoes, which pose no safety concerns, have medicinal effects. In the future, sweet potatoes may be developed into cholesterol-lowering drugs.”
As age increases, blood cholesterol levels gradually rise. When levels become too high, they can trigger hyperlipidemia and arteriosclerosis.
