The #1 Best Tea for Diabetics

FGO Organic Chamomile Tea

  • Best to regulate blood sugar
  • Good against insomnia

What Is Tea and Where Does It Originate From?

Tea is one of the most consumed drinks in the world. Tea is a hot drink made from an infusion of the leaves and buds of the tea plant, Camellia Sinensis. The difference between black tea and green tea is, among other things, the moment of picking and the treatment of the leaves after picking. There is no green tea or black tea plant. The processing of the leaves after picking determines the type of tea.

The plant originally comes from China. I was discovered by Emperor Shen Nung. He boiled his drinking water and added some leaves. This turned out to taste good. In Europe, we were introduced to the beverage in 1610. The Dutch East India Company brought the first shipment ashore.

Can Tea Lower Blood Sugar?

Yes, it can. It's not a substitute for insulin but when you drink certain teas right after your meals it can help lower your blood sugar levels. Not only can tea help in managing and lowering your blood sugar it may also help in preventing complications linked with diabetes.

The research concluded that “consuming tea daily with meals is a good way to prevent and self-treat diabetes, hyperglycemia and any negative effects on our health.

On the other hand, people with diabetes do well to follow the instructions of their treating physician thoroughly regarding diet, exercise, and treatment. In any case, an extra walk of 30 minutes a day has an already proven positive effect on diabetes, and we cannot say that any tea has the same effect, for the time being.

Another beneficial factor is that teas are great for systolic blood pressure and insulin sensitivity.

Making a cup of tea is easy, but brewing a cup of tea in the right way is another story. Sometimes making tea is seen as a ritual, but making tea can also be simple.

  • Do not use water that has been boiled before for tea.
  • Preheat your teacup.
  • Depending on which tea you brew, the water should have a different temperature;
    • for white and green tea: 168-185 °F (76-85 °C)

    • all above temperatures apply to loose tea. For tea bags, you use water that just barely boils. 
  • Drain the water from your preheated teacup and put loose tea in a tea strainer. 
  • Pour the tea with the water at the correct temperature. If you immediately make a whole pot of tea, count 1 cup of water per teaspoon of tea (or per bag).
  • Let the tea steep. You can use these target times:
    • oolong tea: 4 to 7 minutes
    • black tea: 3 to 5 minutes
    • green tea: 2 to 3 minutes
