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 doesn't consist mostly of protein (first option is wrong as a balanced diet needs a variety of nutrients, not just protein dominance).
• It doesn't need equal amounts of protein, carbohydrates, and fats (second option is wrong as different nutrients have different recommended proportions, e.g., carbohydrates should be a larger portion in a healthy diet).
• A balanced diet includes sufficient quantities of all essential nutrients (like vitamins, minerals, proteins, carbohydrates, fats) in appropriate amounts, not excessive or insufficient (this matches the definition of a balanced diet).
• The number of meals and their calorie - per - meal uniformity isn't the definition of a nutritionally balanced diet (the fourth option is about meal structure and calorie distribution per meal, not the nutritional balance of the diet's components).

Answer:

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