Objective: Vegetable intake in Japan is still stagnant at about 280 g per adult per day, and there is a large gap with the intake target of 350 g (Ministry of Health, Labor and Welfare (2020)). On the other hand, according to a survey conducted by the Ministry of Agriculture, Forestry and Fisheries, 70% of the Japanese people are aware that they are consuming the target amount of vegetables. It is possible that Japanese people continue to eat a diet that is deficient in vegetable intake without correctly recognizing their own vegetable intake. Therefore, we will confirm the relationship between the amount of green and yellow vegetable intake, awareness of green and yellow vegetable intake, and intake behavior. Then, clues for increasing vegetable intake will be examined. In this study, the amount of carotenoids in the blood was used as an index of green and yellow vegetable intake.
Methods: A questionnaire survey was conducted on 2,646 adult male and female subjects regarding the measurement of blood carotenoid levels and their awareness and intake behavior regarding the intake of green and yellow vegetables. To determine the amount of carotenoids in the blood, we used a device (Vegemeter, LLC Japan Co., Ltd.) to noninvasively measure the amount of carotenoids in the blood.
Results: As a result of the blood carotenoid measurement, the estimated score was 2.49% for vegetable intake of 350 g or more. On the other hand, 97.51% of the subjects had an estimated score of less than 350 g of vegetable intake, of which 47.33% were aware of their vegetable intake. This indicates that about half of the subjects perceived their vegetable intake to be adequate, even though they did not consume more than 350 g of vegetables.
