One seaweed superfood is so packed with protein that some fans call it a “vegetarian meatball” — and it’s also been linked to slower brain aging.
Packed with vital nutrients, the tiny aquatic plant could prevent cognitive decline and conditions like Alzheimer’s disease, according to some research.
It may even help with weight loss and improve metabolism.
The Mankai plant, a type of duckweed known scientifically as Wolffia globosa, is native to Southeast Asian countries including Thailand, Laos, India, China and Myanmar. It can also be found in parts of the Americas.
And it packs quite the nutritional punch, especially when it comes to the brain.
A 2022 study found that those who ate less red meat and more foods high in polyphenols — including Mankai plant and green tea — experienced reduced cognitive decline.
It’s also a staple of the “green” Mediterranean diet. Like the original Mediterranrean diet, the “green” version is low in carbs and high in healthy fats and vegetables — plus it adds Mankai, walnuts and green tea. Throwing in those extras amplifies the benefits, including when it comes to brain health.
Mankai’s mind-enhancing power is thanks to polyphenols, plant-based compounds that are high in antioxidant and anti-inflammatory properties.
Polyphenols work to protect the brain in a number of ways, such as reducing inflammation, improving memory and promoting better cognitive function.
But it isn’t just a brain boosting food: It also provides several nutrients and is even a good vegetarian source of protein.
A complete protein, mankai contains all nine essential amino acids, making it a plant protein powerhouse.
It’s even been dubbed a “vegetarian meatball” in Southeast Asia due to it’s nutritional profile being 45% protein — similar to that of eggs.
As part of a high-protein, plant-based diet — and when combined with regular physical activity — Mankai could help with weight loss and managing type 2 diabetes, evidence suggests.
But the nutritional benefits don’t stop there.
It also contains vitamin B12, a necessary nutrient for DNA and red blood cells that’s especially tough for vegans and vegetarians to consume enough of. Not only is this plant an excellent source of B12, it’s also highly absorbable in humans.
Another benefit? The plant — which grows on top of water and has a similar shape to a clover — could be good for those who are low in iron, as a study in the Journal of Nutrition on iron-deficient rats found that Mankai reversed their anemia in rats.
Also a source of heart-healthy omega-3 fatty acids, it provides some cardiovascular boosts, especially as part of the “green” Mediterranean diet with a focus on healthy fats.
Finally, it contains vitamin A, which has immune boosting benefits and helps strengthen eye sight.
While a relatively low-risk food, mankai could still be susceptible to trace elements and contaminants, depending on where it’s grown and harvested.
But overall, not only is mankai a highly-nutritional food, it’s also sustainable, growing faster than some crops like corn with less water.
