Cut out all processed food, including bread, cake, biscuits, pastries, sweets or savory junk food. Increase your protein inc. beans, lentils, chickpeas, eggs, meat and some dairy (ideally fermented ie. yoghurt, not milk) and include in every meal and snacks. Protein is essential for the production of neurotransmitters needed to support depression and IBS, immune system for UTIs and to regulate blood sugar levels in diabetes. Drink minimum 2 liters water daily. Have Epsom salt baths (300gms salt) daily. Drink green vegetable drinks. All your conditions can be significantly reduced or possibly gone.
