Explaining himself, he observed that in thousands and thousands of colonoscopies he has done and peering into each and every patient’s intestine, he found that Japanese (who are fond of green teas) has unhealthy gut or stomach characteristics. In fact, tea instructors who obviously consume considerable amount of green tea at regular basis incur stomach issues known as Atrophic Gastritis. This stomach problem is an antecedent to stomach cancer later on if left unchecked.
In a nutshell, Hiromi asserted that his 300,000 clinical observations as general surgeon specializing in gastrointestinal wellness, bring him to conclude that someone with poor gastrointestinal function is never healthy at all. And it might be hard for us to take in, that green tea is one drink that might lead to this.
Now, we are being educated unwittingly that we always see health at a selective and specialized nutrition. Seeing a particular tree for a forest. A particular antioxidant for a green tea.
Take for example Polyphenol found in green tea, there is no question this antioxidant neutralizes and puts free radicals in check inside our body. However, when several of these antioxidants (polyphenols or others), are fused it becomes a corrosive substance known as tannins. Tannin is the reason why some plants and fruits have biting taste in it. Tannin is easily oxidized by air or water. And when it does, it turns to Tannic Acid.
It turns out, according to Hiromi’s clinical observation, tannic acid has corrosive effect on our intestinal mucosa. This mucosa is an essential membrane that line the wall of our stomach. This corrosive effect of tannic acid causes stomach issues such as ulcers.
The mucosal membrane is literally wasting away. In the long run, this atrophic change turns to chronic gastritis. And this long enduring gastric disturbance in turn can lead to stomach cancer. This was observed by Hiromi Shinya in the stomach of his patients who are avid drinkers of tea beverages – could it be Green Tea, Chinese Tea, English Black Tea or Coffee containing high amount of tannic acid.
