Macronutrients are the three primary nutrients our bodies need in large quantities: carbohydrates, proteins, and fats.
宏量营养素是我们身体大量需要的三种主要营养素：碳水化合物、蛋白质和脂肪。
A balanced diet ensures adequate intake of macronutrients for optimal health.
平衡饮食确保了充足的宏量营养素摄入，以维持最佳健康状态。
The recommended daily allowance of macronutrients varies based on age, gender, and physical activity level.
根据年龄、性别和身体活动水平，推荐的每日宏量营养素摄入量会有所不同。
Carbohydrates provide energy for the body, while proteins help build and repair tissues.
碳水化合物为身体提供能量，而蛋白质则有助于构建和修复组织。
Proteins are essential for growth, as they contain amino acids needed for new cell formation.
