What is eating a wide selection of foods with and among the major food groups called?

Eating a wide selection of foods with and among the major food groups is called a balanced diet.

Here's why:

* Variety: A balanced diet emphasizes consuming different foods from each food group. This ensures you get a wide array of nutrients.

* Balance: It's about getting the right proportions of macronutrients (proteins, carbohydrates, and fats) and micronutrients (vitamins and minerals).

* Moderation: It involves consuming foods in appropriate quantities, avoiding excessive intake of any particular food group or nutrient.

So, "balanced diet" is the most accurate term to describe this approach to eating.
