According to the Dietary Guidelines for Americans, persons in the United States aged ≥2 years should increase their intake of certain nutrient-rich foods, including fruits and vegetables. Fruits and vegetables contribute important nutrients that are underconsumed in the United States. Higher intake of fruits and vegetables might reduce the risk for many chronic diseases including heart disease, stroke, diabetes, and some types of cancer. In addition, replacing high-calorie foods with fruits and vegetables can aid in weight management. However, most persons in the United States do not consume the recommended amounts of fruits and vegetables and other healthier food groups (e.g., whole grains or fat-free or low-fat dairy foods).
根据《美国膳食指南》,美国2岁及以上人群应增加某些营养丰富食物的摄入量,包括水果和蔬菜。水果和蔬菜含有在美国摄入不足的重要营养素。增加水果和蔬菜的摄入量可能会降低许多慢性疾病的风险,包括心脏病、中风、糖尿病和某些类型的癌症。此外,用水果和蔬菜替代高热量食物有助于控制体重。然而,美国大多数人并未摄入推荐量的水果、蔬菜及其他更健康的食物类别(如全谷物或无脂或低脂乳制品)。
