Implementation Tips

• Start with a Clean Slate: Begin by eliminating all high-FODMAP foods for 3 to 8 weeks, noting any changes in symptoms.
• Introduce Gradually: Reintroduce foods one at a time, with a 3-day interval between new foods to monitor symptoms accurately.
• Keep a Food Diary: Record everything you eat and any symptoms you experience to help identify specific triggers.

Consulting a Dietitian

It’s highly recommended to undertake the FODMAP diet under the guidance of a dietitian. They can provide personalized advice and ensure your diet remains balanced and nutritionally adequate.

By carefully managing your intake of FODMAPs, you can identify which foods are problematic for you and adjust your diet accordingly to minimise digestive discomfort and improve your quality of life.
