You may have low magnesium from inflammation, chronic diarrhea, or removal of your jejunum or ileum. Foods with magnesium include beans, fortified cereal, green and leafy vegetables, nuts, and whole grains.
Potassium. Your body needs it for healthy muscles, cells, and blood pressure. Crohn’s symptoms like vomiting and diarrhea may lower your potassium level. Foods rich in potassium include beans, carrots, cucumbers, dairy products, eggplant, fish, leafy greens, potatoes, poultry, pumpkins, tomatoes, and zucchini.
