最近听一本书（The Longetivity Paradox)，讲到GUT HEALTH， DIABETES 与 普洱茶。就在网上搜罗了一下。
结果发现中文内容基本没有讲到这一点。
只有两个英文资料有：

为了方便，相关内容如下：
#5 Boost Gut Health
Your gut health is vital. It contains trillions of bacteria. Some are important for your overall health, while others may increase your risk for specific problems.
Did you know that 70 – 80% of your immune system is contained in your gut?
A healthy gut is key to reducing your risk for certain chronic conditions. For example, type 2 diabetes, obesity, cardiovascular disease, and inflammatory bowel disease (IBD) are linked to poor gut health.
Black tea contains polyphenols that help prevent the growth of harmful bacteria like Salmonella. In addition, it encourages the growth of good bacteria that help eliminate bloating and repair tears in the digestive tract lining.
2. 《THE LONGEVITY PARADOX》
如果听这部书，大概在1：50：00 左右。
觉得不可思议，普洱茶被炒得价值连城，可是竟然没有这一亮点？
