If you have constipation, you have probably been told to eat more prunes.
But if you also have IBS, they may not be the best place to start.
Prunes contain fibre, but they also contain sorbitol and fructans. These are FODMAPs that can draw water into the bowel and help you poo, but may also trigger bloating, wind, pain or urgency.
Two alternatives I often prefer are:
🥝 Two green kiwifruit per day
This low FODMAP serving has been shown to improve constipation and abdominal comfort. You also get fibre, vitamin C and other micronutrients. The research used peeled kiwi, so eating the skin is optional.
🥄 Psyllium husk
This soluble, gel-forming fibre holds water and adds bulk to your stool. It is slowly fermented, so it tends to cause less gas than highly fermentable fibres. You can also start with a small amount and gradually adjust the dose.
One trial found that two green kiwifruit increased complete bowel movements more than psyllium. However, another study found that kiwi, psyllium and prunes all improved constipation, with no clear winner for the main outcome.
Kiwifruit did cause the fewest side effects and had the highest patient satisfaction.
But constipation is not always solved by adding one food or supplement.
Inside my Take Control process, we first stabilise the foundations, then personalise the strategy based on your symptoms and finally integrate it into everyday life.
Because the goal is not simply to make you poo.
It is to help you achieve comfortable, predictable bowel movements without triggering other IBS symptoms.
