Which is said to be an "empty" source of energy?
A. Unlike other macronutrients, ethanol cannot be stored in the body.
B. The metabolism of ethanol uses more energy than it provides.
C. The energy from ethanol cannot be used in the body.
D. Ethanol has no additional nutritive value.
Answer (2)
Ethanol is considered an 'empty' source of energy primarily because it does not provide any additional nutritive value to the body, lacking essential nutrients. Although it contains calories, its energy usage during metabolism can surpass the energy it supplies, categorizing it as contributing empty calories. Therefore, the correct choice highlighting this aspect is that ethanol has no additional nutritive value. ;
Ethanol is classified as an 'empty' source of energy due to its lack of essential nutrients and the fact that it may require more energy to metabolize than it provides. Thus, the correct answer is D: Ethanol has no additional nutritive value.
; Ethanol as an 'Empty' Source of Energy
Ethanol, which is a type of alcohol commonly found in beverages, is often referred to as an 'empty' source of energy. This classification is primarily due to several characteristics that distinguish ethanol from other sources of energy like carbohydrates and fats.
Key Reasons Why Ethanol is Considered 'Empty'
**Nutritional Value:** Ethanol has no essential nutrients. Unlike the macronutrients proteins, fats, and carbohydrates that provide vitamins and minerals, ethanol gives only calories without any significant nutritional contribution. **Caloric Content vs. Energy Use:** Ethanol contains approximately 7 calories per gram. However, the process of metabolizing ethanol can require more energy than the energy it provides. This means your body might expend more calories breaking down ethanol than it actually receives from it. **Health Implications:** Consuming ethanol does not aid in meeting dietary needs and can lead to health issues, including addiction and liver problems. Thus, it is seen more as a source of 'empty calories' rather than beneficial energy.
Given all these points, the most accurate statement from the provided options is D. Ethanol has no additional nutritive value . This statement encapsulates the essence of why ethanol is considered an empty source of energy.

For instance, a drink with ethanol may provide calories, but it won't offer vitamins or minerals. This is why many consider drinks like beer or cocktails as 'empty' calories, as they fill you up without providing needed nutrients.
Research in nutrition confirms that while ethanol provides calories, it does not promote health through nutrients, making it an empty calorie source according to dietary guidelines.
