Athlete's foot is a disease caused by fungal infection. There are no special dietary requirements for this disease, but it is advised to avoid chili peppers and alcohol during the treatment period. Common foods like eggs are permissible. During treatment, it is important to maintain a regulated diet and lifestyle habits. Do not go to public baths or swimming pools. Try not to wear shared slippers casually. Household footbaths and foot towels should be used separately and frequently disinfected with sunlight. The use of topical antifungal creams should be prolonged, with a minimum duration of one to two months, to potentially eliminate the fungus completely. After recovery, it is crucial to prevent recurrence by avoiding spicy and irritating foods and not staying up late.
