Tea helps the digestive system to do its job more efficiently

Several studies have proven that drinking tea during or after meals aids digestion by relieving stomach gas and flatulence. But it should be kept in mind that not all types of tea exert beneficial effects on digestion. Green tea and herbal teas like ginger tea are found to be the best bet in aiding the process of digestion as they contain high amounts of antioxidants and polyphenols. Here is how green tea helps keep heart diseases at bay

Tea helps the digestive system to do its job more efficiently by stimulating the production of saliva, bile and gastric juice for better digestion. It also contains antioxidants that act as powerful anti-inflammatory agents that are found to reduce certain digestive complications. Green tea and herbal tea contain polyphenolic compounds namely catechins that increase the activity of the digestive enzyme, pepsin that helps in the breakdown of dietary proteins in the stomach. 

Some studies have shown that phenolic compounds present in tea interfere with the absorption of iron by forming iron-complexes in the intestinal lining of the stomach. It is recommended that one should consume foods rich in iron and vitamin C if they wish to drink tea with meals to lower its effects on iron absorption.

Hence, drinking tea with meals is not good for patients with iron-deficiency as tannins present in tea hinder the process of iron absorption in the body. It is also found that consuming tea during meals decreases the availability of catechins to the body — compounds that are present in tea and play a vital role in various physiological profiles. Hence, if you wish to drink tea with or after your meals, you can choose between green tea or ginger tea as they are found to aid digestion. And people suffering from iron-deficiency should restrict intake of tea during meals or consult their healthcare professional to prevent health complications.
