每日摄入量的百分比。。
食品营养成分标签上列出的百分比代表一份食品提供的每种营养素的推荐每日摄入量的百分比。

例如，如果食品标签上注明一份特定食物可提供每日钙摄入量的 15%，则意味着食用一份该食物可提供每日推荐钙摄入量的 15%。

这些百分比基于各种膳食参考值，例如美国食品和药物管理局 (FDA) 等监管机构制定的推荐膳食摄入量 (RDA) 或充足摄入量 (AI)。

这些百分比可以帮助您了解食物的营养成分以及它如何满足您的日常整体营养需求。 通过比较不同食品标签上的百分比，您可以对所食用食品的营养成分做出明智的选择。

请务必注意，营养成分标签上的百分比是基于每日 2,000 卡路里饮食的一般建议，可能无法反映您的特定营养需求。 个人饮食需求可能因年龄、性别、活动水平和整体健康状况等因素而异。 咨询医疗保健专业人士或注册营养师可以提供更多关于解释和使用营养成分标签的个性化指导，以满足您的特定营养目标。
The percentages listed on food nutrition facts labels represent the percentage of the recommended daily intake of each nutrient that is provided by one serving of the food.

For example, if a food label states that a serving of a particular food provides 15% of the daily value for calcium, it means that consuming one serving of that food contributes to 15% of the recommended daily intake of calcium.

The percentages are based on various dietary reference values such as the Recommended Dietary Allowances (RDAs) or Adequate Intakes (AIs) established by regulatory authorities like the Food and Drug Administration (FDA) in the United States.

These percentages can help you understand the nutrient content of the food and how it contributes to your overall daily nutrient needs. By comparing the percentages on different food labels, you can make informed choices about the nutrient composition of the foods you consume.

It's important to note that the percentages on nutrition facts labels are based on general recommendations for a 2,000-calorie daily diet and may not reflect your specific nutrient requirements. Individual dietary needs can vary based on factors such as age, sex, activity level, and overall health. Consulting with a healthcare professional or a registered dietitian can provide more personalized guidance on interpreting and using nutrition facts labels to meet your specific nutritional goals.
