The Reference Nutrient Intake (RNI) is significant in nutrition primarily because it provides guidelines for the amounts of essential nutrients that individuals should aim to consume. These values are established to help ensure that dietary needs are met for the majority of the population, which is crucial for maintaining optimal health.

In the context of meal planning, understanding RNI allows individuals, nutritionists, and dietitians to create balanced meals that provide the necessary nutrients required for growth, maintenance, and health. For example, by referencing the RNI for specific vitamins and minerals, meal planners can design menus that meet these nutritional needs, ensuring that individuals get the right amount of nutrients essential for their age, sex, and life stage.

The other options do not relate to the primary functions of RNI. It does not dictate food prices, ensure food safety, or regulate food additives, as these areas are governed by different standards and regulatory frameworks. Thus, the emphasis on RNI in meal planning highlights its role in promoting informed dietary choices and fostering nutrient adequacy in the diet.
