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, Camelia 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.

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

How do I make tea?

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.

  • Bring water to a boil. If possible use filtered water.
  • 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)
    - for oolong tea: 185-208 °F (85-98 °C)
    - for black tea: 212 °F (100 °C)
    - for pu-erh tea: 212 °F (100 °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 of 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
    - other types: 2 minutes or longer if needed
  • Stir the tea before drinking.

Tea is sensitive to light, heat and odor transfer. Therefore always keep it in a dry, cool and dark place.

Does 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 lowering your blood sugar. Not only can tea help in managing and lowering your blood sugar it may also help in preventing complications linked with diabetes.

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 to have the same effect, for the time being.
