Fitness buff Vidya Malavade recommends lemon juice, apple cider vinegar, and ginger tea to improve digestion. Lemon juice might improve enzyme production and regulate stomach acid. Apple cider vinegar with its acetic acid may enhance enzyme activity and increase stomach acid production. Ginger tea's gingerol and zingerone may reduce inflammation, promote digestion, and reduce bloating. However, a consultant gastroenterologist advises consulting a doctor before using apple cider vinegar regularly and emphasizes that individual responses may vary. Ultimately, good digestion habits like eating slowly and staying hydrated are key.
