The Benefits of Green Tea and the Dangers of Excess.4

Green tea is one of the most popular varieties, and not just because people like the flavour. One of the healthiest drinks on the market, green tea is highly regarded and has recently attained superdrink status. Because brewed green tea is mostly water, it lacks the typical macronutrients included in other foods and beverages. Unsweetened tea has no calories and contains no fat, carbs, or protein. Its reputation for being healthful comes from substances called catechins. A review found that these catechins had anti-inflammatory, antibacterial, and even anti-cancer properties. They are also thought to offer probiotic
advantages.

What Potential Health Advantages Could Green Tea Possess?
The advantages of green tea may include:
1 Greater Mental Acuity During lengthy, demanding cognitive tasks.
A review indicated that caffeine, especially the quantity in matcha, increased alertness, arousal, and vigour.
2 Defence Against Cardiovascular Disease Antioxidants included in green tea may help control cholesterol levels and lower high blood pressure (hypertension), hence lowering the risk of heart disease. According to a Japanese study, those who drank five or more cups of green tea daily had a 26 percent lower risk of dying from cardiovascular disease over the course of seven years than those who drank just one cup.
3 Reduce Cholesterol
According to a comprehensive review and meta-analysis, drinking green tea reduces LDL ("bad") cholesterol levels in persons of all body weights.
4 To prevent cancer
Some scientists think catechins can inhibit the free radicals that cause cancer. However, the National Cancer Institute states that there isn't enough evidence to support the claim that drinking green tea can prevent cancer.
5 Lower Diabetes Risk
Daily green tea consumption was linked to a lower risk of type 2 diabetes and a lower risk of all causes of mortality in diabetes patients in a study including half a million Chinese individuals.

What Adverse Reactions Could Too Much Green Tea Have?
Green tea has numerous benefits that have been established to be healthy and safe, but like with any food or beverage, there can be too much of a good thing. Green tea contains caffeine, thus consuming too much of it might induce the typical side effects of caffeine overuse, including jitteriness and difficulty falling asleep.Consuming strong extracts of green tea can potentially have a negative impact on the liver. According to a study, women who consumed a high quantity of green tea extract daily—the equivalent of five cups of brewed tea—developed elevated levels of liver enzymes, which may point to damaged liver cells.

Summary
Numerous studies support the health benefits of green tea, a plant-based beverage that has been used medicinally for millennia. It is a popular beverage as well as an ingredient to add to other cuisines and wellness products due to its high concentration of antioxidants and adaptability. However, because it includes caffeine, it's crucial to utilise supplements and extracts with caution and only in the approved dosages.
