Since the overall nutritional status of the general population has improved nowadays and manufactured formulas contain vitamin D, the prevalence of vitamin D deficiency rickets has significantly decreased. Recently, however, 4 cases with lower extremity deformities came to the outpatient department. Among them, 1 case consumed only Sunsik (a powder mixture of several grains and fruits) instead of the manufactured formula, to control atopic dermatitis, 2 cases stopped eating due to diarrhea from milk feeds, and to control atopic dermatitis. 1 case was on a normal diet without any specific allergic reaction to foods, but had very less exposure to sunlight. Providing sufficient vitamin D and calcium, along with increasing the time of sunlight exposure have significantly improved the hematologic and radiologic findings, and the bone growth. The authors will explain the necessity of adequate supplementation of vitamin D and calcium, especially in cases which control or restrict their diet due to food allergies.
