Green tea contains many antioxidants and polyphenols, including catechins, epigallocatechin gallate (EGCG), and caffeine. Green tea helps prevent cancer, heart disease, diabetes, obesity, and Alzheimer’s disease.
1. Cancer prevention
Cancer is caused by genetic mutations that
occur over time. Green tea inhibits the growth of tumors and prevents them from
spreading throughout the body. It works by stopping cells from dividing
uncontrollably, which stops the formation of cancerous tumors.
2. Heart disease
The flavonoids in green tea help lower
cholesterol levels and reduce the risk of cardiovascular disease. Green tea may
also protect the heart by preventing blood clots.
3. Diabetes
Diabetes is a condition where the pancreas
does not produce enough insulin. Insulin is necessary to convert sugar into
energy. Green tea helps regulate glucose levels in the blood, which reduces the
risk of diabetes.
4. Weight loss
Green tea increases metabolic rate, which
burns calories faster than normal. Drinking at least three cups of green tea
per day may help people lose weight.
5. Memory improvement
A study published in the Journal of
Agricultural and Food Chemistry showed that rats who drank green tea improved
their memory compared to those who did not drink it. Researchers believe that
the catechins in green tea may have positive effects on brain function.
6. Skin care
Tea tree oil is effective against acne-causing
bacteria and fungi. Tea tree oil also cleanses pores and removes excess oils
from skin.
