When dealing with amebiasis, avoiding certain foods can aid recovery and prevent irritation. Stay away from greasy, fried, or processed foods, as they can upset your digestive system. High-fiber foods like raw vegetables and whole grains may worsen diarrhea, so opt for cooked vegetables and low-fiber options. Dairy products, especially if you're lactose intolerant, can exacerbate symptoms. Sugary foods and drinks can feed the parasites, so limit sweets and sodas. During treatment with nitazoxanide 500mg, stick to a bland diet with easily digestible foods like bananas, rice, and boiled potatoes. Stay hydrated and follow your healthcare provider’s dietary recommendations.
