Page Medically Reviewed and Edited by Cyrus Khambatta, PhD
Normally, when you think of the side effects of green tea, you may be thinking of some pretty negative things.
But not all side effects are bad. In fact, there are plenty of beneficial side effects that you should, and will, know about.
These “side effects” have been shown to improve your health, fight off free radicals that could cause many different chronic diseases, and improves brain health.
If you consume too much green tea (in excess of 5 to 6 cups), you may experience some side effects that may be less than optimal for your body.
So, even though we are going to go over the positive side effects, it’s important for you to understand that drinking MORE is not going to enhance these benefits.
Now, before we go into the side effects, let me first introduce you to everything that green tea is…
The Powerful Drink That Is Green Tea
Green tea, which has been a staple in India, China, and other Eastern countries, may add tremendous benefits to your health.
It hasn’t been until recently that green tea has increased in popularity in the US.
Next to water, green tea is the second most consumed beverage in the world. It even beats out rival coffee, as the go-to drink from older adults all the way to millennials.
Green tea is unoxidized, and is probably the least processed tea around. This means there is a higher concentration of antioxidants, polyphenols, and catechins compared to other tea brands, such as black tea leaves.
It is quickly growing in popularity, thanks in part, to the powerful antioxidant EGCG.
EGCG, which is the main catechin in green tea, has been extensively researched and shown to improve your health in many different ways.
In fact, EGCG may improve heart health, brain health, and even boost your weight loss (who doesn’t want to lose weight?).
But it’s not just a powerful drink, In places like China and India, green tea is also used for its medicinal properties, and its ability to improve (or even reduce the risk) for many different chronic diseases.
Now, it’s time for what everyone’s been waiting for…the positive side effects of green tea…
The Powerful Side Effects Of Green Tea On Your Health
Now that we are to the “meat” of the article, let’s dive in, feet first, and find out the powerful benefits of drinking green tea.
And hey, if you’re not a green tea drinker yet, by the end of this list, you should be. Here are some of the benefits you may see from including green tea in your daily nutrition plan:
1. Green Tea Contains Bioactive Compounds
Green tea contains some pretty awesome compounds that have been shown to improve your health.
From polyphenols and antioxidants, to the catechin, EGCG, there are many good things to rave about.
These compounds may improve your health, prevent cell damage, and lower inflammation in your body.
Green tea contains roughly 30 percent polyphenols, which includes large amounts of the catechin, EGCG.
Once inside your body, these antioxidants, polyphenols, and catechins go to work, protecting your cells, and preventing damage associated with free radicals.
2. Green Tea Improves Weight Loss
Everyone is looking to lose weight. It could be a few pounds…or 50, 60, or even 100 pounds.
And most do everything they can to make it happen. They cut down on calories, switch to low-carb, low-fat, or some other fad diet in order to lose the weight, and burn off excess fat in the process.
However, if they only included green tea in their plan, they may be a bit more successful.
Studies show that green tea may boost metabolic rate by 4 percent and fat oxidation (or fat burning) by a whopping 17 percent!
Plus, the caffeine content may mobilize fatty acids in the body, therefore enabling them to be used for energy, or to increase performance.
3. Green Tea May Prevent Diabetes
Diabetes is a disease that impacts over 400 million people worldwide. This disease, characterized by high blood sugar or an inability to use insulin, may lead to many other health conditions.
This disease may increase your risk for blindness, liver and kidney issues, heart disease, and brain-related issues.
Green tea may protect you from diabetes. Studies show that green tea may naturally lower blood sugar levels by increasing your body’s sensitivity to insulin.
To show just how effective green tea is for preventing diabetes, a Japanese study showed a 42 percent lower risk for developing diabetes in green tea drinkers.
4. Green Tea May Reduce Heart Disease Risk
Heart disease, heart attacks, and strokes are the leading cause of death and disability around the world.
Highlighted by high blood pressure, elevated cholesterol, and increased blood fat levels, this disease is continuing to climb, with one out of every four people having a heart attack or stroke.
Thanks to the antioxidant levels, green tea may increase the antioxidant capacity in your body. And the higher your antioxidant capacity, the less risk there may be for oxidation of LDL cholesterol particles.
This is important, since oxidized LDL cholesterol may be the first major step to developing heart disease.
Other studies have shown green tea may improve total and LDL cholesterol numbers, and your triglyceride levels.
Green tea drinkers, according to several studies, may be 31 percent less likely to develop cardiovascular disease.
5. Green Tea Reduces Body Fat
You already know that green tea may increase your weight loss. But did you know it could help you boost your body fat loss?
Studies show that green tea may decrease body fat levels, especially in the belly area.
In one study, green tea drinkers showed significant decreases in body weight, body fat percentage, belly fat, and waist circumference.
The Take Home Message on Green Tea
Green tea is the second most consumed beverage in the world. Popular in China and India, it is slowly becoming the most popular go-to drink for your health.
Studies show that green tea may boost heart health, liver and kidney health, brain health, weight loss, and may even prevent age-related brain disorders.
These powerful side effects are due to the powerful antioxidants, polyphenols, and catechins (namely EGCG ) that are found in this beverage.
If you’re looking to reap the positive side effects, then you should increase your green tea intake, with Amla Green Tea, to rush flush your body with the antioxidants and polyphenols it needs to stay healthy and fit.
