Mung bean compounds and health effects studied

What it found

Mung bean and its extracts have been tested for effects on blood sugar, blood fats, blood pressure, cancer cells, the liver and the immune system, mostly in lab and animal studies.

Only a few small trials in people have been done.

What they found

Studies in people

Blood sugar in people

In a trial of 18 healthy people, cooked mung bean noodles gave low metabolic responses, similar to raw starches from wheat, manihot and smooth peas. In 8 healthy men, mung bean starch had a lower glycemic index (51) than cornstarch (95).

Protein isolate trial

In a double-blind trial of 44 healthy subjects, taking 3.0 g per day of mung bean protein isolate for 8 weeks significantly decreased insulin levels and insulin resistance scores. Plasma glucose showed a downward trend but was not significantly changed.

Prediabetes trial

In a double-blind trial of 45 prediabetes patients, taking 2.5 g of mung bean protein twice daily for 12 weeks stabilized fasting plasma glucose and insulin levels compared to placebo. Triglyceride levels significantly decreased in subjects with hyperlipidemia.

Animal and lab studies

Blood sugar in animals

Rats fed mung bean starch with high amylose had a lower glycemic index than rats fed waxy cornstarch. The mung bean starch diet increased glucose oxidation in diabetic rats, suggesting better insulin action.

Blood pressure in animals

In spontaneously hypertensive rats, a single oral dose of mung bean protein hydrolysate (600 mg/kg) decreased systolic blood pressure by 30.8 mmHg at 6 hours, and the effect lasted at least 8 hours.

Studies in people and animals

Cancer and immune effects

In lab tests, mung bean peptides, proteins and phenolic acids showed dose-dependent anti-proliferative effects against several cancer cell lines. In mice, aqueous extracts of fermented mung bean delayed breast cancer formation and reduced tumor cell division.

What the authors conclude

“The mung bean contains abundant nutrients and bioactive compounds, especially polyphenols, polysaccharides, and polypeptides, and it possesses various pharmacological properties.”

Also in their conclusions

  • They conclude that the mung bean contains abundant nutrients and bioactive compounds and possesses various pharmacological properties.
  • They suggest that consumption of mung bean-based functional products and nutraceuticals could be considered an alternative food, not just in Asian countries but also in other countries.
  • They advise that further research is needed to unravel other main functional components and to understand how food processing methods affect the physiochemical properties of the mung bean.

How it was done

The authors wanted to pull together research on the bioactive compounds in mung bean, because a detailed compilation was lacking. They also wanted to show how mung bean might prevent disease and encourage its use as a functional food.

They reviewed published studies on mung bean polyphenols, polysaccharides and peptides, including lab tests, animal experiments and a small number of human trials. The human trials included 18 healthy people eating mung bean noodles, 8 healthy men given mung bean starch, 44 healthy subjects taking mung bean protein isolate, 45 prediabetes patients taking mung bean protein, and children with diarrhea given a mung bean-based rehydration solution.

What it can’t tell you

  • Most of the studies in this review were done in lab dishes or animals, so they cannot show what happens in people.
  • Only a few small clinical trials in people have been done, so the health effects in humans are not well established.
  • The review cannot show whether mung bean prevents any disease, because the studies looked at markers like blood sugar or blood pressure, not long-term outcomes.
