Green tea has been called one of the healthiest beverages you can drink on the planet. Loaded with antioxidants and nutrients that have powerful positive effects on your body, green tea could definitely be your go-to drink to improve your overall health. Here are the top 5 health benefits of green tea:
1. Improve Brain Function
While it doesn’t contain as much as coffee, the key active ingredient in green tea is caffeine. In our brains caffeine blocks an inhibitory neurotransmitter, increasing the firing neurons and the concentration of neurotransmitters like dopamine and norepinephrine. Study after study has shown that the proper amount and use of caffeine consistently leads to improvements in various aspects of brain function, including improved mood, vigilance, reaction time and memory.
2. Lower Risk of Cancer
Cancer is caused by the uncontrolled growth of cells, which is commonly caused by oxidative damage. Antioxidants have been proven to help prevent this type of damage from taking place. Green tea is an excellent source of antioxidants and therefore has been reported to build up the body’s protection against cancer. An example of this is a study that has shown that women who drank the most green tea had a 22% lower risk of developing breast cancer, the most common cancer in women.
3. Protect Your Brain from Cognitive Decline:
Not only have reports shown that drinking green tea help your brain in the short term, as you age drinking more green tea has been shown to lower the risk for cognitive decline and deterioration. With Alzheimer’s and Parkinson’s disease becoming more and more common, the bioactive compounds in green tea have been reported to have various protective effects on neurons and may reduce the risk of both diseases.
4. Boost Metabolism:
Studies have shown that green tea can boost the metabolic rate leading to decreases in body fat, especially in the abdominal area. A study performed on a controlled trial of 240 men and women that went on for 12 weeks found that the group that drank green tea had significant decreases in body fat percentage, body weight, waist circumference and abdominal fat. This can be attributed to the polyphenol found that works to intensify levels of fat oxidation and the rate at which your body turns food into calories.
5. Good for the Heart
A 2013 review of many studies found the proper amount green tea helped prevent a range of heart-related issues from high blood pressure to congestive heart failure. By improving blood flow and lower cholesterol, green tea is one of the best drinks to help achieve heart health.
