People with diverticulosis have a very weak digestive system. That is why their bowels are forming ‘pockets’ or ‘pouches.’ The short-term goal is to prevent this condition from getting worse and severely impacting our daily life. The long-term goal is to strengthen the intestines so the pouches will be closed.
So at the minimum, a diverticulosis patient must remove from his diet any food that can add further stress and make digestion more difficult. A very oily diet like fried food using animal fats is one such ‘must avoid.’ This tends to stick to the bowel walls. It makes the contraction of the muscle walls which move food along the digestive organs a lot more difficult. Processed and fast foods high in preservatives also can weigh down the health of our bodies including the digestive system. The blood vessels supplying oxygen and nutrients to the bowels get inflamed will have a very bad effect in the long run.
Plant-based oils like olive oil, on the other hand, has the opposite, beneficial effect. It supports the blood vessel health supplying the bowels and helps prevent inflammation, helping to keep them healthy.
