Black tea is associated with lower risk of type 2 diabetes

Some people can not start the day without a sip of coffee while others prefer to drink tea. If you are in the second group, try to make sure that your cup is full of black tea, since consuming it frequently has been associated with a lower risk of developing type 2 diabetes.

We have told you about the benefits of yerba mate tea for diabetes . An international study discovered similar benefits in black tea.

As a cold or hot infusion, black tea is one of the most popular drinks on the planet. In addition to stimulating the nervous system like all drinks with caffeine, its regular consumption has previously been associated with a lower risk of developing type 2 diabetes . The different investigations that supported this belief were reaffirmed by a study carried out by the publication Data Mining International in Geneva, Switzerland.

The researcher Ariel Beresniak, director of the study, and his colleagues decided to analyze the consumption of black tea in 2009, in 50 countries on all continents and compared that level of consumption with the rates of diabetes and cancer  and other health conditions (respiratory, infectious and cardiovascular diseases) in those countries. The comparison showed the following: rates of type 2 diabetes are lower in countries where a lot of black tea is used.

The country with the highest consumption of black tea in the study was Ireland, with an average of 2 kilos (4.4 pounds) per year per person, followed closely by the United Kingdom and by Turkey. By contrast, the lowest levels of black tea consumption were recorded in South Korea, Brazil, China, Morocco and Mexico.

Although the statistics showed a reduction of the rates of diabetes in the countries of greater consumption, the study does not show causality between the greater consumption of black tea and the development of diabetes. There was also no association of black tea with any of the other health conditions considered in the study.

What could be the added benefit of tea? The researchers suggest that it is due to the large variety of complex flavonoids contained in black tea, which are released through the infusion process. Flavonoids are vegetal pigments of which, until now, about 600 are known. Their botanical function is to attract the pollinating agents of the plant from which they come, and in the human diet they offer certain health benefits due to their properties antioxidants, anti-inflammatory and antimicrobial.

If you already drink black tea regularly, congratulations, as it could help reduce your risk of developing type 2 diabetes, a condition that is increasing by leaps and bounds globally. According to calculates the International Diabetes Federation, the 285 million people affected by the condition in 2010 will increase to 438 million in 2020. But you should drink black tea in moderation, since its excess (more than five cups a day) , can cause adverse effects due to caffeine. Among these are:

  • Headache
  • Nervousness
  • Difficulty to sleep
  • Vomiting and / or diarrhea
  • Irritability
  • Arrhythmias
  • Heartburn
  • Dizziness and ringing in the ears
  • Confusion

Other people who should avoid drinking too much black tea include pregnant women (no more than 2 cups a day equivalent to 200 mg of caffeine) or those who are breastfeeding, as well as people with anemia .

Now you know that the steaming cup of tea you enjoy after your meal can lower your risk of developing type 2 diabetes. But of course, do not leave it all to tea. Do your part with a balanced diet  and a good exercise plan.
