You have probably heard about the health benefits of green tea again and again.
But what if you don’t like green tea?
Then you’ll be happy to learn that researchers from Mahidol University in Bangkok have recently published a study in the Asia Pacific Journal of Clinical Nutrition showing that another (much more popular) tea is just as good or even better for treating type-2 diabetes.
In fact, it prevents spikes in blood sugar even after consuming pure sugar.
Researchers recruited 24 subjects aged 20–60. Some were prediabetic and the others had normal glucose control.
They gave the participants a sugar drink followed by either black tea or caramel-colored water with no health properties.
Those who drank the black tea had much lower glucose levels than those who drank the caramel-colored water.
This relationship held for both the prediabetics and the normal subjects, but the effect was larger in the prediabetic group.
In other words, black tea can keep your glucose levels down, even after consuming sugar that would usually spike your blood sugar.
The compound in black tea responsible for this effect is probably black tea polymerized polyphenol (BTPP). Based on previous studies, the authors suggested that this has antioxidant, anti-inflammatory, and blood pressure-lowering effects. Apparently, it blocks our bodies from absorbing carbohydrates.
In fact, other studies have shown that countries (and areas) where black tea consumption is high have lower rates of type-2 diabetes.
