FANCL Corporation analyzed the relationship between 'breakfast' and 'nutritional status and health concerns' among 26,489 breakfast eaters. This data was extracted from a total of 33,246 men and women aged 20 to 69 at the time of their first purchase of the custom-made supplement 'Personal One.' The analysis was based on urine test results and dietary/lifestyle questionnaire responses accumulated from healthy individuals through the sale of the product.
The results revealed that individuals whose breakfast consists of 'nakashoku' (referring to pre-cooked foods such as store-bought bento boxes, instant foods, and deli items, including bread) have lower sufficiency levels of zinc and calcium compared to those eating other types of breakfast. Their levels showed a similar trend to those who skip breakfast entirely. Furthermore, it was confirmed that a significantly higher percentage of people eating 'nakashoku' for breakfast reported feeling fatigue and stress.
## [Survey Results Topics]
1. People whose breakfast is 'nakashoku' have low vitamin and mineral sufficiency
Compared to those eating non-nakashoku breakfasts, they tended to have lower sufficiency of vitamins and minerals. In particular, 'zinc' and 'calcium' levels were on par with those who skip breakfast.
2. People whose breakfast is 'nakashoku' are prone to feeling fatigued
Compared to non-nakashoku eaters, a higher percentage answered that 'fatigue tends to linger,' 'they get tired/lack stamina when moving for a long time,' and 'they tire more easily than before.'
3. People whose breakfast is 'nakashoku' are prone to feeling stress and mood disruptions
Compared to non-nakashoku eaters, a higher percentage answered that 'they cannot relieve stress,' 'they feel irritated,' and 'they feel gloomy.'
*Analysis targeted 26,489 breakfast eaters out of 33,246 men and women aged 20 to 69 at the time of their initial purchase of the custom-made supplement 'Personal One.' Comparisons were made between those who answered their breakfast was 'nakashoku (pre-cooked foods such as store-bought bento boxes, instant foods, deli items [including bread])' and those who answered other than nakashoku (excluding those who skip breakfast).
Since launching our supplement sales in 1994, our company has supported the health of many customers through 'health foods.' Recently, with the diversification of lifestyles, we feel the growing importance of 'sleep' and 'exercise.' Therefore, as this business enters its 31st year, to stay close to the health of even more customers, we will evolve into a 'Health Support Company.' This means strengthening the elements of 'sleep' and 'exercise' in addition to our traditional 'dietary (nutritional)' support via health foods, providing total support for our customers' well-being.
As part of this effort, to raise awareness about the importance of 'diet,' 'sleep,' and 'exercise,' we will regularly publish the 'FANCL Health Big Data Survey,' which analyzes urine tests and dietary/lifestyle questionnaire responses from over 30,000 people. This time, we summarized the results analyzing the relationship between 'breakfast' and 'nutritional status/health concerns.'
