Which of the following is considered a rapidly metabolizable carbohydrate?

• A. Whole grain bread
• B. Juice
• C. Potato chips
• D. Steak

Answer: (B)

Juice is considered a rapidly metabolizable carbohydrate because it typically contains simple sugars, such as glucose and fructose, which are quickly absorbed into the bloodstream. This rapid absorption results in a quick increase in blood glucose levels, providing an immediate source of energy. In contrast, whole grain bread contains complex carbohydrates, which take longer to digest and metabolize, leading to a more gradual rise in blood sugar. Potato chips, while they have a high glycemic index due to their processed nature, are often high in fats and not primarily a carbohydrate source. Steak, being a protein-rich food, does not contain significant amounts of carbohydrates at all. Therefore, juice stands out as the best example of a rapidly metabolizable carbohydrate.
