"Design an ultra-minimalist, monochrome logo for a nutrition and dietetics clinic. The initials A, D, and S should be formed from smooth, rounded lines, shaped like stylized fruits or vegetables, such as an apple for A, a carrot or cucumber for D, and a broccoli or other vegetable for S. The design should focus solely on clean, flowing curves, without any flowers, leaves, or unnecessary details. The monochrome color scheme should convey simplicity, elegance, and a focus on health and natural wellness."
