With diverticulitis, you can still eat Mexican food, but there are some ingredients that you may need to avoid.
The diet high in red meat and refined grains, with low fiber content can increase the risk of diverticulitis. Substituting red meat with poultry or fish may reduce risk.
Also high FODMAP foods could cause diverticulitis symptoms, including onions, mushrooms, cauliflower, and garlic, apples, apricots, dried fruit, pears, peaches
dairy foods, including milk, yogurts, and cheeses, legumes and pulses, bread and cereals, sugars and sweeteners. As some of these foods also contain beneficial fiber, it would be better to discuss food choices and elimination with a healthcare professional.
Since each person is different, if you notice a certain food causes pain or a change in symptoms, you could eliminate that food and talk to your doctor or healthcare provider.
