Dietitian's Tips for Consuming Lemon

  • Metabolic Effect: Lemon supports the immune system with its high vitamin C content and increases iron absorption in the body. It also facilitates digestion and speeds up metabolism.
  • Consumption Recommendation: It can be added to warm water in the morning to start the day, or it can be used to add flavor to salads and meals. It enhances the flavor especially when used in meat and fish dishes.
  • Things to Consider: It is important to rinse your mouth with water after drinking lemon water as it can damage tooth enamel. One lemon juice meets approximately half of the daily vitamin C requirement.
  • Exercise Equivalent: It is enough to take a light-paced walk for about 5 minutes to burn the calories from one lemon. This can be easily balanced even with small activities during the day.
