7 Health Benefits of Green Tea
It is now a widely known fact that many teas (except that sugar bombarded sweet teas) including green tea, black tea, and white tea have health benefits, especially the benefit of getting rid of free radicals in our body. But among all teas, green tea is found to be the most effective antioxidant, and it also helps to keep our body moisturized. According to WebMD, antioxidants such as Epigallocatechin gallate (EGCG) and polyphenol in green tea also help to prevent prostatic and breast cancer. Researchers say that although more research has to be done, green tea definitely has health benefits.
1. Green Tea Protects the Heart
Most teas help to reduce the risk of heart disease, but green tea especially excels in helping the coronary artery to maintain a healthy blood pressure. The antioxidant known and flavonoid helps the endothelial cell to function better, thus preventing thrombus or blood clots.
2. Green Tea Enhances the Immune System
One research revealed that green tea stops proliferation of certain cold viruses. This is due to green tea's effect of increasing the regulator T cell.
3. Green Tea Promotes Weight Loss
Green tea also helps with weight loss. Health.com reported that drinking 5 cups of green tea a day has the effect of burning fat naturally. A research done in 2011 found that when rats were put into high-fat diet along with green tea, they gained weight slower than without green tea.
4. Green Tea Promotes Healthy Aging
A research done on 14,000 people over the age of 65 found that the most people who drank green tea coped with the symptoms of aging more easily. The people who drank at least 5 cups of green tea daily were able to perform daily activities such as taking a shower and putting on a clothes 7% more easily.
5. Green Tea Helps to Prevent Diabetes
A research done in 2006 by the American Diabetes Association found that among 17,000 Japanese people, the people who drank at least 6 cups of green tea daily had 1/3 lower risk of diabetes.
6. Green Tea Lowers Cholesterol
Polyphenol in green tea stops the absorption of cholesterol, and this aids in lowering the bad cholesterol (LDL). But the green tea's ability to lower cholesterol isn't significant, so people who are taking cholesterol lowering prescriptions shouldn't stop taking their medication.
7. Green Tea Improves Memory
Antioxidant EGCG in green tea helps preserving memory. A recent research revealed that green tea promoted the growth of new brain cells in rats, thus improving memory and learning ability.
Recent research done by a research team from the Third Military Medical University in China has revealed that green tea also promotes better memory. The research revealed that the chemicals in green tea activated the brains cells, promoting better memory and spatial skills.
The research team focused on the organic chemicals called the epigallocatechin gallate (EGCG). The research team found that EGCG promotes formation of neural progenitorcells, which help cells such as stem cells adapt and grow better. The team also observed what effect does EGCG has on the hippocampus, the part of the brain where short and long-term memories are processed.
The team divided the test rats into two groups, one that was administered with EGCG and one that was not. Both groups were trained to find their ways through a maze for three days, then the light source was dimmed, making them to depend solely on their memory to find their way out of the maze. The group administered with EGCG were able to find their way out of the maze quicker, confirming that EGCG improves object recognition and spatial skills.
The research team said: "It is widely known that green tea helps to prevent cardiovascular disorders, but this research has identified that the chemicals in green tea affects brains cell reaction, thus helping to prevent degenerative disease and memory loss." The result of this research was featured on Molecular Nutrition & Food Research Journal, and was covered by British news Daily Mail on 9/6/2012.
