Summer heat can negatively impact digestion, leading to issues like bloating and loss of appetite. In India, Imli paani (tamarind water) and Nimbu paani (lemonade) are popular summer drinks that help with hydration. Research indicates that tamarind water is effective for serious gut health issues, while lemonade contains bioactive compounds that support hydration and bowel movement. According to Dr. Saurabh Sethi, a gastroenterologist, both drinks affect the gut through their acidity, making moderation essential. Imli paani can stimulate digestion but may irritate those with acid reflux, whereas Nimbu paani is gentler and helps prevent constipation. Nutritionist Nmami Agarwal emphasizes that both drinks can be beneficial but should be consumed mindfully, avoiding excess sugar and artificial flavors. Ultimately, the best choice depends on individual digestive needs, with recommendations to consult a nutritionist if trying them for the first time.
