Objectives:
Dietary fats are one of the well-known stimulators of carotenoid absorption, but the effects of the quantity and the type of dietary fats on carotenoid absorption have not yet been studied systematically. Therefore, this review article has been conducted.
Do dietary fats improve the absorption of carotenoids?
Study design:
This review article included a total of 27 in vitro studies and 12 RCTs.
Results and conclusions:
The investigators found meta-regression of in vitro studies showed that the bioaccessibility of carotenoids, except for lycopene, was positively associated with the concentration of dietary fats.
The investigators found meta-analysis of RCTs showed that the bioavailability of carotenoids was enhanced when a higher quantity of dietary fats was co-consumed.
The investigators found, moreover, fats rich in unsaturated fatty acids resulted in greater improvement in carotenoid bioavailability [SMD = 0.90, 95% CI = 0.69 to 1.11] as compared with fats rich in saturated fatty acids [SMD = 0.27, 95% CI = 0.08 to 0.47].
The investigators concluded that co-consuming dietary fats, particularly those rich in unsaturated fatty acids, with carotenoid-rich foods can improve the absorption of carotenoids.
