People consume green tea as it offers a lot of health benefits. It is rich in antioxidants and nutrients that help to boost metabolism, promote weight loss, and improve brain function. However, like everything in life, excess consumption of green tea can have side effects on the body. This article will speak about the side effects of overconsumption of green tea intake.
Green tea contains caffeine, a natural stimulant that helps to increase alertness and reduce fatigue. However, too much caffeine intake can cause adverse effects such as anxiety, jitteriness, and insomnia. According to the US Food and Drug Administration (FDA), the recommended daily caffeine intake for an adult is 400mg. A cup of green tea contains approximately 30–50mg of caffeine. Therefore, consuming more than 8 cups of green tea per day can lead to caffeine overdose.
A type of polyphenol, tannins is present in green tea which gives it a bitter taste. They are known to interfere with the absorption of iron and other minerals in the body. This can lead to digestive problems such as constipation, stomach cramps, and nausea. Additionally, green tea contains catechins, another type of polyphenol that can cause acidity and heartburn in some people.
Overconsumption of green tea can have adverse effects on the liver. It contains high levels of catechins, a type of antioxidant that can cause liver damage when consumed in large quantities. According to a study published in the journal Hepatology, excessive green tea intake can lead to liver toxicity, which can cause liver failure and even death.
The fluoride content in green tea makes your teeth strong. However, the intake of fluoride in overabundance can have adverse effects on bone health. According to a study published in the Journal of Toxicology and Environmental Health, green tea when consumed excessively can cause skeletal fluorosis, a condition that weakens the bones and can lead to fractures.
As mentioned earlier, green tea contains tannins, a type of polyphenol that interferes with the absorption of iron in the body. This can lead to iron deficiency, a condition that can cause fatigue, weakness, and anemia. According to a study published in the American Journal of Clinical Nutrition, consuming green tea with meals can reduce the absorption of iron by up to 70%.
Caffeine in green tea acts as a natural stimulant that can cause headaches in some people. Additionally, the tea has theanine, an amino acid that promotes relaxation and reduces stress. But, if green tea is taken on large amounts it can lead to dizziness.
Pregnancy and Breastfeeding
According to a study published in the American Journal of Obstetrics and Gynecology, consuming more than 300mg of caffeine per day during pregnancy can increase the risk of miscarriage and low birth weight. Additionally, caffeine can pass into breast milk and affect the baby’s sleep patterns and behavior.
