A high-fiber diet (more than 30g fiber per day) promotes eupepsia and protects against many diseases (e.g. intestinal coronary, gallstones). The diet is useful for weight reduction/ maintenance as it causes a feeling of satiation and has a positive effect on blood sugar levels.
A change in diet should take place step by step, as it may initially cause bloatedness and wind. Sufficient liquid intake should also be ensured, to allow fiber to swell and to avoid constipation.
