Medical Video: Green Tea Side Effects and Who Must Avoid It
Apart from being unique, green tea is preferred because it has many important benefits. However, according to the latest research, drinking too much green tea is actually a risk for health. In the study, the researchers revealed how excessive green tea can interfere with the reproductive function of fruit flies and the development of their offspring. Then how does the impact of drinking green tea mostly on humans? Here is the review.
Effect of green tea on health
Green tea comes from the leaves of the Camellia sinensis plant. Green tea is one of the least processed forms of tea so that it can maintain high levels of antioxidants and polyphenols. These two flowers are known to be very beneficial for health.
Previous studies have shown that green tea can help reduce weight, reduce cholesterol, and protect the body from several diseases. Including cancer, heart disease, and Alzheimer's disease.
For maximum benefit, just drink green tea
A recent study conducted at the University of California looked at the effect of green tea on fruit fly larvae. Fruit flies are often used to study human diseases because they have 75 percent similarity to genes that cause disease in humans.
Researchers found that exposure to 10 milligrams of green tea caused the development of fly larvae more slowly. In addition, there is a drastic decrease in the number and size of the offspring. In addition, the researchers also found that exposure to 10 milligrams of green tea caused deformities in the reproductive organs of fruit flies, including testicular and ovarian atrophy.
Although the study does not explain how green tea can affect the development and reproduction of fruit flies, researchers suspect that high doses of green tea can trigger apoptosis or excessive cell death and cause these abnormalities.
What happens if you drink green tea too often?
1. Excess caffeine
Green tea is a drink that contains caffeine so that it can cause side effects such as palpitations, abdominal pain, anxiety, anxiety, insomnia, and tremors. The amount of caffeine content varies by product. However, on average green tea contains 30 milligrams of caffeine in each bag that is brewed.
If you drink green tea very often, chances are you will experience caffeine dependence. So when you don't drink tea that contains caffeine, you will experience caffeine withdrawal symptoms that are characterized by drowsiness, dizziness, headaches, and easily provoked emotions.
2. Disorders of iron absorption
Tea contains antioxidants called flavonoids. This content can provide a protective effect from free radicals that can cause damage to cells in the body. However, flavonoids can bind iron, so iron cannot be absorbed by the body.
Drinking green tea at mealtime or afterwards can reduce iron absorption by about 70 percent. Therefore, you should not drink green tea during meals or a few hours afterwards.
3. Excess calories
Green tea is healthy, but if you don't eat it wisely, you can be excess calories. For example if you drink green tea in bottles or cans that have added sugar and sweeteners. The sugar and sweetener certainly contain calories.
More calorie intake than the calories you burn will cause an increase in body fat, so that it can cause conditions such as obesity and diabetes mellitus (diabetes).
4. Medical complications
Although green tea is safe, drinking green tea can mostly worsen the medical conditions of some people. For example, people who suffer from anxiety disorders will get more anxious and people who suffer from diarrhea can experience more severe digestive system disorders.
Green tea may also not be safe in people with anemia, glaucoma, heart disease, and bleeding disorders. If you have these medical conditions, you should consult your doctor about the limits on the amount of green tea consumption that is still relatively safe for you.
