Nuts in their raw form are a great source of protein and healthy fats, but they’re also difficult to digest, which can make them tough for anyone suffering through a Crohn’s flare, says Kelly Kennedy, a licensed dietitian/nutritionist in Massachusetts. “For a better option, opt for smooth nut butters such as natural peanut butter,” she says.
Seeds can also wreak havoc on your stomach if you have Crohn’s disease. “When passing through the digestive tract, seeds don’t get fully digested,” Kennedy says. “Because of this, they can sometimes lead to worsened diarrhea if you’re going through a Crohn’s flare.” Foods you may want to avoid include those with a lot of seeds such as raspberries, strawberries, tomatoes, chia, and flax seeds.
