5. Green Tea May Protect Your Brain in Old Age, Lowering Your Risk of Alzheimer’s and Parkinson’s

Not only can green tea improve brain function in the short term, it may also protect your brain in old age. Alzheimer’s disease is the most common neurodegenerative disease in humans and a leading cause of dementia. Parkinson’s disease is the second most common neurodegenerative disease and involves the death of dopamine producing neurons in the brain. Multiple studies show that the catechin compounds in green tea can have various protective effects on neurons in test tubes and animal models, potentially lowering the risk of Alzheimer’s and Parkinson’s.

6. Green tea can kill bacteria, which improves dental health and lowers your risk of infection

The catechins in green tea have other biological effects as well. Some studies show that they can kill bacteria and inhibit viruses like the influenza virus, potentially lowering your risk of infection.

Streptococcus mutans is the primary harmful bacteria in the mouth. It causes plaque formation and is a leading contributor to cavities and tooth decay. Studies show that the catechins in green tea can inhibit the growth of streptococcus mutans. Green tea consumption is associated with improved dental health and a lower risk of caries.

7. Green tea may lower your risk of type ii diabetes

Type II diabetes is a disease that has reached epidemic proportions in the past few decades and now afflicts about 300 million people worldwide. This disease involves having elevated blood sugar levels in the context of insulin resistance or an inability to produce insulin. Studies show that green tea can improve insulin sensitivity and reduce blood sugar levels.

One study in Japanese individuals found that those who drank the most green tea had a 42% lower risk of developing type II diabetes. According to a review of 7 studies with a total of 286,701 individuals, green tea drinkers had an 18% lower risk of becoming diabetic.

8. Green tea may reduce your risk of cardiovascular disease

Cardiovascular diseases, including heart disease and stroke, are the biggest causes of death in the world. Studies show that green tea can improve some of the main risk factors for these diseases. This includes total cholesterol, LDL cholesterol and triglycerides.

Green tea also dramatically increases the antioxidant capability of the blood, which protects the LDL cholesterol particles from oxidation, which is one part of the pathway towards heart disease.

9. Green tea can help you lose weight and lower your risk of becoming obese

Given that green tea can boost the metabolic rate in the short term, it makes sense that it could help you lose weight. Several studies show that green tea leads to decreases in body fat, especially in the abdominal area. One of these studies was a randomized controlled trial in 240 men and women that went on for 12 weeks. In this study, the green tea group had significant decreases in body fat percentage, body weight, waist circumference and abdominal fat.

10. Green tea may decrease your risk of dying and help you live longer

Of course, we all have to die eventually. That is inevitable. However, given that green tea drinkers are at a lower risk of cardiovascular disease and cancer, it makes sense that it could help you live longer. In a study of 40,530 Japanese adults, those who drank the most green tea (5 or more cups per day) were significantly less likely to die during an 11 year period.

Death of all causes: 23% lower in women, 12% lower in men.

Death from heart disease: 31% lower in women, 22% lower in men.

Death from stroke: 42% lower in women, 35% lower in men.

Another study in 14,001 elderly Japanese individuals aged 65-84 years found that those who drank the most green tea were 76% less likely to die during the 6 year study period.#
