Chinese Yam

(Nagaimo, iron yam, japanese/chinese yam)

has antioxidants and is anti inflammatory.

believed to help regulate blood sugar levels due to its high resistant starch content, which isn’t digested in the small intestine and can promote healthy gut bacteria.

contains digestive enzymes that aid in breaking down food and prevent a heavy feeling in the stomach.

reported to improve coughing and dyspnea associated with lung deficiency.

strengthens the functions of the spleen, kidney, liver, and stomach, to decrease phlegm, and heal fatigue, chronic diarrhea, and diabetes.

contains various chemical components, including starch, non-starch polysaccharides, fiber, protein, allantoin, dopamine, batatasins, phytic acid, choline, and ergosterol.

also made up of 1–3% protein, but dried yam is more concentrated, comparable to cereal grains.

also contains abscisin II, allantoin, batatasins, choline, dopamine, glucoprotein, mannan, phytic acid, polysaccharides, and minerals such as calcium, copper, iron, magnesium, manganese, phosphorous, potassium, and zinc.

Boiling Chinese yams can reduce their resistant starch content by 80%.

Resistant starches benefit short-chain fatty acid production in the large intestine, inhibiting hepatic cholesterol synthesis and suppressing colon cancer cell proliferation in vitro.

You can find this at Hmart or other asian food markets. Great in soups.
