Why Has ICMR Advised Against Tea Or Coffee Around Meals?

The Indian Council of Medical Research (ICMR) recently issued 17 dietary guidelines for Indians, emphasizing a balanced diet and healthy lifestyle. One guideline from the National Institute of Nutrition (NIN), part of the ICMR, suggests moderating tea and coffee consumption due to their caffeine content.

Although tea and coffee are popular beverages in India, the ICMR warns against consuming them immediately before or after meals. The caffeine in these drinks stimulates the central nervous system and can lead to physiological dependence, according to ICMR researchers.

While complete avoidance isn't necessary, the ICMR advises Indians to be mindful of their caffeine intake. A 150ml cup of brewed coffee contains 80-120mg of caffeine, while instant coffee contains 50-65mg, and tea contains 30-65mg.

The ICMR recommends limiting daily caffeine intake to 300mg and avoiding tea or coffee at least one hour before or after a meal. This is because tannins in these beverages can interfere with iron absorption, reducing the availability of iron in the body.

Iron is crucial for haemoglobin production, which carries oxygen in red blood cells. Lower iron levels can lead to iron deficiency and symptoms like fatigue, weakness, and pale skin. However, consuming tea without milk may offer health benefits like improved blood circulation and reduced risk of coronary artery disease and stomach cancer, according to ICMR researchers.
