Purpose:
In this study, we focus on the relationship between carotenosis and hyperlipidemia. Because carotenoids are lipophilic, they are more soluble in blood with high lipid levels. Therefore, it is considered that hyperlipidemic patients show carotenosis more strongly than healthy subjects.
Methods:
The palm where carotenosis is likely to appear is measured. Carotenoids are intake by 200 mL of 100% fruit juice of an orange. The average of the red values obtained from the images is evaluated.
Results:
A significant difference was confirmed from 30 min after the carotenoid intake.
Conclusion:
In the future, increasing the number of subjects and doses of carotenoids will be considered for more reliable verification.
