Benefits of Green Tea for Health
To get excellent health every person should do a healthy lifestyle and eat. Good food and drinks will support the nutrients needed by the body. In addition, some foods will also provide protection for the body (immune system). One of the famous drink is green tea. Let us discuss some of the benefits of green tea here.
1. Contains Antioxidants
Well, when we eat or drink, our bodies must turn food into energy. As a result, this produces some by-products in our body called free radicals. Free radicals can damage our cells and may be drivers in aging.
But do not be afraid, we can counter the negative effects of free radicals by consuming antioxidants, and one of the best ways to do this is by drinking green tea.
In a clinical trial published by the American Society for Nutritional Sciences, scientists found that many studies have shown that tea consumption can have a positive health impact. The hypothesis behind this benefit comes from high levels of flavonoids, antioxidants that fight free radicals.
2. Fighting cancer
Green tea has been shown to activate an internal cancer-preventing enzyme that can inhibit tumor growth. Many teas are packed with antioxidants, but the direct mechanisms of cancer prevention have not been fully formed. The good news is there is a link between cancer prevention and tea consumption.
An ongoing study of women with breast cancer suggests that polyphenols in green tea can slow down proteins that are part of tumor cell growth.
3. Capability improvement
In particular, green tea drinkers show increased connectivity in the important parts of the brain associated with
A study with healthy male volunteers found that when given a soft drink containing green tea extract, those who consumed green tea extract not only showed increased connectivity in the brain, but also improved performance on working memory tasks.
4. Calming the mind
Green tea contains l-theanine compounds. l-theanine can help you to relax and avoid anxiety.
A study published in the Journal of Trends in Food Science & Technology states that theanine acts as a neurotransmitter that increases alpha waves in the brain. Alpha waves are considered as indicators of relaxation. Human volunteers are given 50-200 mg l-theanine and are shown to increase alpha waves without sleepiness.
5. Heart Health
According to Harvard Heart Letter, Japanese adults who drink more than five cups a day are 26% less likely to have heart attacks or strokes. While research around the mechanism of action is limited, there is no red flag, so there is nothing wrong.
In another study, Athens Medical School brought 14 volunteers and asked them to drink green tea or caffeinated hot water. Using blood pressure and ultrasound cuffs to check whether arteries are widening or not, doctors found that those who drank green tea had significantly wider arteries, which meant lower risk of heart disease such as atherosclerosis.
