Green tea has been used for many years as a medicine. It is loaded with antioxidants that are known for many health benefits. Now Japanese researchers have suggested that green tea can help combat food allergies. A food allergy occurs when your immune system overreacts to a food or a substance in a food. The researchers from Shinshu University in Japan found that drinking green tea increases the abundance of gut bacteria that helps suppress allergic immune responses. The bacteria, Flavonifractor plautii (FP), has been known to be a part of the catechin metabolism in the intestines. Catechin is an antioxidant found in a variety of foods including green tea. The research team found that oral administration of FP strongly suppressed the Th2 immune response to food allergies in vivo. As drinking green tea increases the abundance of FP in the gut, the study suggested that catechin in green tea could help fight food allergies. However, the researchers noted that more studies are needed to look into the safety of FP before it can be used as a probiotic to treat allergies. But you can start drinking green tea from now to get these evidence-based benefits:



Improves brain function: Green tea contains less caffeine than coffee, but enough to boost brain function. Studies have shown caffeine can improve various aspects of brain function, including mood, vigilance, reaction time, and memory.



Reduces bad breath: Studies also suggest that the catechins in green tea can inhibit the growth of bacteria in the mouth, and reduce bad breath.



Cuts risk of developing type 2 diabetes: People with Type 2 diabetes have elevated blood sugar levels, which may be caused by insulin resistance or an inability to produce insulin. Research shows that green tea can improve insulin sensitivity and reduce blood sugar levels.  Also Read - 6 Advice For Diabetes Patients During The Cold Season
