NutritionThe problem of poor nutrition amongst women in their 20s

Physical size (percentage of women per BMI category)

As obesity arising from Westernization of the Japanese diet becomes increasingly common, so does another health issue: that of undernourishment amongst young women. According to a study by the Ministry of Health, Labour and Welfare, at least 1 in 5 women in their 20’s report a BMI of lower than 18.5, which is considered “too thin.”*1

Annual changes in energy intake (women)
Intake of key nutrients

One reason for this is insufficient energy intake. Women in their 20’s also have other nutritional deficiencies, such as an average daily intake of only 220.8g of vegetables (the “Healthy Japan 21” daily target is 350g), 6.2mg of iron (6-10.5mg recommended), 405mg of calcium (650mg recommended), and 11.5g of fiber (18g or more recommended).*2*3
