Research on Mankai Duckweed and Blood Sugar Control

Introduction to Mankai Duckweed

Researchers have recently explored the impact of the Mankai duckweed plant (Wolffia globosa Mankai) on blood sugar regulation. This green aquatic plant, enjoyed in South Asia for centuries, is known for its high protein content, earning it the nickname “vegetable meatball.” Comprising over 45% protein, Mankai contains nine essential and six conditional amino acids.

Growing Conditions and Sustainability

Primary producers of Mankai duckweed include Israel and other countries with similar climates. The plant can be cultivated hydroponically, allowing year-round growth. Notably, Mankai requires less water per gram of protein produced compared to other protein-rich plants such as kale, soy, and spinach.

Clinical Trial on Glycemic Control

A research team from Ben-Gurion University of the Negev (BGU) investigated the effects of Mankai duckweed on glycemic control following carbohydrate intake. The findings were published in the American Diabetes Association’s journal, Diabetes Care.

The study involved two groups of overweight participants, averaging 51 years of age. One group consumed a Mankai duckweed shake for two weeks, while the other group had a yogurt shake. Both beverages contained equivalent calories, carbohydrates, protein, and lipids.

Findings of the Study

At the two-week follow-up, blood sugar sensors indicated that participants who consumed the Mankai duckweed shake experienced lower blood sugar peaks. Additionally, these peaks occurred later and returned to normal more quickly than in the yogurt shake group. Participants who drank the Mankai shake also reported feeling more satiated.

Nutritional Benefits of Mankai Duckweed

Previous research has highlighted Mankai’s rich nutritional profile, which includes phenolic acid, flavonoids, dietary fiber, minerals like iron and zinc, and vitamins A, B complex, and B12. Mankai has been shown to enhance iron and folic acid levels and provides a comparable amount of essential amino acids as soft cheese and peas. The researchers propose that Mankai duckweed has significant potential to be classified as a ‘superfood.’

Conclusion

In addition to its health benefits, Mankai is tasteless and odorless, making it easy to incorporate into meals. Recently, the Harvard School of Public Health added Mankai smoothies to its cafeteria menu, further endorsing its versatility and health advantages.
