The gut has become central to the health world. Its connection to the brain and its relationship to serious diseases and inflammation make it remarkable. Researchers are exploring the diverse world of the gut microbiome and the ways diet and exercise influence it. Many recommend revising your diet to include foods that have a positive impact on your intestines. Another consideration that scientists are pursuing is the powerful effects of green tea.
Green tea for intestinal health
Many change their diet by adding more fruits and vegetables to promote their gut health. Others add fermented foods or probiotic and prebiotic supplements – all to improve their gut health. Another simple, small addition to your daily routine can make a huge difference in your gut microbiome: green tea.
New research looks at the potential of green tea to bring about positive change in an imbalanced gut. Few human studies have been conducted, but this limited research is promising. Drinking green tea seems to lead to good bacterial growth in your intestines and reduces some harmful bacteria. Green tea contains a high concentration of powerful antioxidants called polyphenols. The intestines can easily absorb the polyphenols abundant in green tea, leading to good bacterial growth. The health benefits that many associate with green tea stem from its positive effect on the intestines.
Intestine and disease
The gut microbiome is a phenomenon with potential keys to many different diseases. Scientists estimate that more than a trillion bacteria line the intestinal tract of every human. When you have a healthy balance of those bacteria, your overall health is likely to be optimal. Likewise, an imbalance in your microbiome, whether it’s the growth of harmful bacteria or a lack of good bacteria, can increase your risk for cancer, obesity and type 2 diabetes.
Scientists are conducting research to determine which types of bacteria are linked to which diseases. They have found certain bacteria linked to a wide variety of conditions and diseases:
- obesity
- certain cancers
- chronic inflammation
- cardiovascular disease
- high blood sugar level
The lining of your intestines is also key to your gut health. With ongoing inflammation and irritation, you can develop a ‘leaky gut’, which is detrimental to your health. All of this points to the crucial role the gut plays in a person’s overall health.
Green tea, the intestines and diseases
While using diet alone to reverse gut imbalances and address disease has not always been successful, research shows that consuming green tea produces significant changes in blood sugar levels, reduces inflammation, and lowers blood triglycerides. These are all risk factors for heart disease, type 2 diabetes and obesity.
Scientists are beginning to test green tea’s ability to reduce disease by targeting risk factors before the development of the disease. This studyconducted at Ohio State University by Richard Bruno and a team of researchers, found that participants had lower blood sugar levels and less inflammation after a month of taking green tea extract compared to a month after not taking the supplements.
What led to this important change? Green tea reversed ‘leaky gut’. Researchers also tested participants for intestinal inflammation and intestinal permeability. Participants with high intestinal inflammation and ‘leaky gut’ at the start of the study benefited from taking green tea extract. After just a month of adding green tea extract to their diet, these participants had a significantly healthier gut microbiome.
Another study looked at the effect of green tea on a number of health factors. This study shows that drinking green tea can lower the risk of cardiovascular disease, certain cancers and cognitive impairment. In addition, drinking green tea also helped people lose weight, improve their metabolic markers and maintain their strength.
More work needs to be done to discover green tea’s full potential for the gut. However, initial studies show that green tea promotes a healthier gut, reversing the effects of ‘leaky gut’ and reducing the risks of diseases such as cardiovascular disease and type 2 diabetes. Green tea is a powerful tool for getting your gut and your health back on track.
