Question

which statement describes a nutritionally balanced diet?
it consists mostly of protein.
it provides equal amounts of protein, carbohydrates, and fats.
it includes enough, and not too much, of all essential nutrients.
it consists of three small meals, each totaling about the same number of calories.

Explanation:

• A nutritionally balanced diet isn't mostly protein (first option is wrong, as it needs a variety of nutrients).
• Equal amounts of protein, carbs, and fats aren't required (second option; different nutrients have different recommended ratios, e.g., carbs should be a larger portion for energy).
• A balanced diet includes sufficient, not excessive, essential nutrients (third option matches the definition: essential nutrients like vitamins, minerals, macronutrients in appropriate amounts).
• Meal frequency and calorie per meal uniformity don't define balanced nutrition (fourth option; it's about nutrient content, not meal size/calorie per meal).

Answer:

It includes enough, and not too much, of all essential nutrients.
