　牛乳は，エネルギーあたりの栄養素密度が高く，歴史的に栄養不良等の回復に役立つという栄養的価値が認識されてきた。牛乳はアミノ酸スコア100と必須アミノ酸のバランスに優れ，食事に組み込むことで，食事全体のたんぱく質の質を高める。また，カルシウムについては含有量が多いだけでなく，食事に牛乳を組み込むことで食事全体のカルシウムの吸収率を高める。不足しがちな栄養素をサプリメントで摂取するのではなく，食品を組み合わせて食べることの栄養学的価値を示す代表的な食品である。さらに，100円あたりの栄養素密度も高く，経済的にも効率的な食品である。

　Milk has been historically recognized as having great nutritional value；its high nutrient density per energy makes it useful for individuals recovering from malnutrition among others. Milk is composed of an excellent ratio of essential amino acids, with an amino acid score of 100, and enhances the protein content when served with a meal. 　Additionally, not only is milk rich in calcium, but the absorption rate of calcium contained in the meal increases when milk is served with a meal. Instead of consuming nutritional supplements to make up for a lack of nutrients in the diet, Milk is a representative food that highlights the nutritional value of taking one food in combination with other foods. Moreover, milk costing as little as 100 contains high nutrient density, making it an economically efficient food.
