Which of the following is a combo item that contains equal parts protein and carbohydrates (1 block of protein equals 1 block of carbohydrate)?

• A. Rice
• B. Milk
• C. Butter
• D. Olive oil

Answer: (B)

The thing this item tests is having both protein and carbohydrates in roughly the same block amount. In this block system, a portion should provide about one block of protein and one block of carbohydrates to be considered a combo item. Milk fits the bill: a typical serving gives around 8 g of protein and about 12 g of carbohydrates, which lines up with roughly one block of each. Rice is mainly carbohydrates with little protein, while butter and olive oil are fats and don’t provide meaningful amounts of protein or carbohydrates. So milk is the only option that delivers a balanced mix of both macronutrients in the expected block terms.
