Final answer:
Price is not a contrast element in meal planning; instead, color, texture, and shape are used to make meals visually and sensory appealing.
Step-by-step explanation:
Price is not a type of contrast to be achieved in meal planning. When planning a meal, chefs and nutritionists often look for contrast in elements such as color, texture, and shape to create appealing and balanced dishes. These contrasts can enhance the dining experience by creating a visual and sensory appeal. For instance, a plate with different colors like green vegetables, red tomatoes, and a white sauce is visually more appealing than a monochromatic dish. Similarly, combining smooth and crunchy textures or varying the shapes of ingredients can make a meal more interesting.
