Background: Serum beta-cryptoxanthin levels are lower in overweight subjects than in normal subjects. Abnormalities of adipocytokine profiles in obesity subjects have been reported. There are several reports that serum beta-cryptoxanthin levels in them were relatively lower than normal subjects.
Objective: We hypothesize that supplementation of highly concentrated beta-cryptoxanthin improves serum adipocytokine profiles in obese subjects. This study tested the association between beta-cryptoxanthin intake and serum adipocytokine levels.
Methods: An intervention study consisted of a 3-week long before-and-after controlled trial, where beta-cryptoxanthin (4.7 mg/day) was given to 17 moderately obese postmenopausal women.
Results: The results indicated no significant changes in body weight or body mass index (BMI). Serum beta-cryptoxanthin levels increased significantly by 4-fold. Serum high molecular weight (HMW)-adiponectin levels increased significantly, while serum plasminogen activator inhibitor (PAI)-1 levels decreased.
Conclusions: We concluded that increasing the intake of beta-cryptoxanthin to approximately 4 mg per day for 3 weeks may have beneficial effects on the serum adipocytokine status and consequently alleviate progression of metabolic syndrome.
