It is important that you get in the habit of drinking at least 1.5 liters of water a day, as it is essential to detoxify your body and keep you well hydrated. Water containing minerals such as magnesium and calcium is especially recommended as it helps improve digestion and purify the body.
On the contrary, avoid carbonated water, since the air bubbles inflame the abdomen. Also avoid soft drinks, fruit juice, excessive coffee and alcohol.
On the other hand, green tea helps reduce stomach inflammation and is very tasty, with a little ginger (which is great for digestion) or lemon juice.
