A black cup of coffee is on many people’s breakfast menu in the morning, but a cup of black tea when waking up certainly won’t hurt either. A new Australian study – which is currently undergoing follow-up research – is the first to show promising results that drinking black tea daily can halve the risk of diabetes. So what do the researchers know? And what is the connection between black tea and your blood sugar levels?
Researchers from both universities in Australia and China want to jointly clarify the health benefits of tea for diabetes patients. According to the new study, drinking a cup of tea every day is one of the small adjustments you can make to combat type 2 diabetes.
The study
562 men and 1,361 women between the ages of 20 and 80 from eight different Chinese provinces took part in the experiment. Of these, 436 participants had type 2 diabetes, 352 had prediabetes, and 1,135 had normal blood sugar levels. The researchers asked them how often and which tea they drink, and then examined the relationship between that data and the amount of glucose in their urine, the extent to which they respond to insulin (insulin resistance) and their experience with (medication for) diabetes.
The participants who drank black tea daily even had a 53 percent lower risk of prediabetes and a 47 percent lower risk of type 2 diabetes.
These first analyzes clearly showed that there was more glucose in the urine of people who drink tea daily and that they respond better to insulin and excrete more blood sugar through urine, which kept their blood sugar levels more stable. Those participants were 15 percent less likely to have prediabetes and 28 percent less likely to have type 2 diabetes than participants who reported never drinking tea. Participants who drank black tea daily even had a 53 percent lower risk of prediabetes and a 47 percent lower risk of type 2 diabetes.
In drawing their conclusions, they took into account known risk factors for diabetes and prediabetes as best as possible, such as age, gender, ethnicity, body mass index (BMI), average blood pressure, cholesterol, smoking, level of exercise, and so on.
What makes black tea so healthy for diabetes patients?
According to the researchers, certain bioactive substances in tea – such as free amino acids and polyphenols – which are mainly produced during the production process of black tea – have an antioxidant and anti-inflammatory effect, reduce insulin resistance and have a positive effect on the cells in the pancreas that produce insulin. .
Promising drug for type 2 diabetes?
To a certain extent, the effect of these substances looks promisingly similar to that of a new drug for diabetes, one that can also have positive side effects for your heart and kidneys. The substances ensure that the kidneys of diabetes patients absorb less glucose, so that more sugar leaves their body through their urine. This is necessary to keep blood sugar levels more stable and to prevent the development of the disease: the latter is now being further investigated in the next phase of the research. Because the follow-up research is still in progress, Flemish experts do not want to make any statements about this for the time being.
The researchers of the study themselves also conclude that important follow-up research is needed to see which other lifestyle habits can influence the results. To prove that drinking tea really has an impact on your blood sugar level, they are now conducting a new study in type 2 diabetes patients. To be continued, but in the meantime it certainly can’t hurt to indulge in a cup of black tea or two.
