In the ideal world your gut should be functioning in optimal condition, however, you can make significant improvements by altering the composition of your diet. Your gut bugs love fibre, this means predominantly whole foods and plants – vegetables, fruit, nuts, seeds and legumes. Omega-3 fats are also essential and can be plant- or fish-based.
Find a functional medicine practitioner in your area, or connect with one online. Functional medicine incorporates a personalised approach. Healthy diet and lifestyle advice is general, you may be targeting a specific health issue and it is prudent to discuss your specific areas of concern or health goals whilst working with a practitioner.
