What Are The 6 Health Benefits Of Green Tea?
In the past 20 years, thousands of studies have shown green tea’s significant health benefits. The benefits start with the catechin content. Catechins are antioxidants that fight and may even prevent cell damage.
So What Are The Specific Health Benefits
1. Heart Health
A 2013 review of many studies found green tea helped prevent a range of heart related issues, from high blood pressure to congestive heart failure. Scientists think it works on the lining of blood vessels, helping keep them stay relaxed and better able to withstand changes in blood pressure. It may also protect against the formation of clots, which are the primary cause of heart attacks.
2. Managing Cholesterol Levels
Green tea reduces bad cholesterol in the blood and improves the ratio of good cholesterol to bad cholesterol.
3. Brain Health
What’s good for the heart is usually good for the brain, and your brain needs healthy blood vessels. In general people who drink green tea have greater activity in the working-memory area of their brains. It has also been shown to help block the formation of plaques that are linked to Alzheimer’s disease. It is said to delay the deterioration caused by Alzheimer’s and Parkinson’s. Studies carried out on mice showed that it protected brain cells from dying and even restored damaged brain cells.
It seems to help keep blood sugar stable which is critical for people with diabetes. Because catechins lower cholesterol and blood pressure, they can protect against the damage a high-fat diet can cause. Green tea apparently helps regulate glucose levels slowing the rise of blood sugar after eating. This can prevent high insulin spikes and resulting fat storage.
5. Weight loss
It can help increase and even change your metabolism so you burn more calories from fat. Studies show that green tea can also help you keep weight off once you’ve lost it. It is the polyphenol found in green tea works to intensify levels of fat oxidation and the rate at which your body turns food into calories.
6. Stress Reduction
Sipping this tea helps you slow down and relax. An amino acid called theanine found in green tea can provide a calming effect. Theanine is an amino acid naturally found in the leaves. It is this substance that is thought to provide a relaxing and tranquilizing effect and be a great benefit to tea drinkers.
Don’t add your tea to boiling water; you’ll kill helpful catechins. It is better if the water is kept at 160 to 170 degrees. It is also helpful if you add lemon. Vitamin C makes the healthy compounds easier to absorb. Dairy, on the other hand, makes it harder to absorb the catechins.
Aim for at least four cups a day, two with caffeine and two without. More than that seems to have little health downside, other than the possible effects of caffeine.
