Duckweed May Help Improve Postprandial Glucose Levels


Mankai
is a protein-rich, aquatic plant strain of duckweed. It has the same
protein profile as eggs and contains the nine essential amino acids.
The mankai strain is particularly rich in iron, zinc, vitamin A,
vitamin B complex and vitamin B12. A new study has found that mankai
may help control blood sugar levels after consumption of
carbohydrates.





Twenty abdominally obese adults with an average age of 51.4 participated in the study. The participants replaced dinner with either a green shake containing mankai or an iso-carbohydrate/protein/calorie yogurt shake for two weeks. The researchers used a glucose monitoring system to assess postmeal glucose responses. Participants filled out dietary, daily activity, satiety scale, and sleep logs.





Participants who drank the mankai shake had a lower postprandial glucose peak
which occurred later compared to those who drank the yogurt shake.
They also returned faster to baseline glucose levels. Morning fasting
glucose levels were lower in participants who drank the mankai shake.
The satiety rank was also higher in the mankai participants.





The study was conducted by researchers from the Ben-Gurion University of the Negev and Tel Aviv University. It was published in the July, 2019 issue of the journal Diabetes Care.
