Aim: To compare the effect of vegetable oils on the uptake of lutein and zeaxanthin by adult retinal pigment epithelial (ARPE)-19 cells .
Methods: ARPE-19 cells were cultured in Dulbecco's Modified Eagle Medium-F-12 supplemented with 10% foetal bovine serum and 1% penicillin-streptomycin in a humidified 5% CO incubator maintained at 37°C. Cells were treated with 247 µmol/L lutein, 49 µmol/L zeaxanthin and 1% (v/v) of either coconut oil, corn oil, peanut oil, olive oil, sunflower oil, soybean oil, castor oil, or linseed oil for 48h. Lutein and zeaxanthin concentration in the cells were quantified by high performance liquid chromatography.
Results: Among the oils tested, the highest lutein and zeaxanthin uptake was observed with coconut oil while the lowest was observed with linseed oil.
Conclusion: ARPE-19 uptake of lutein and zeaxanthin are found to be dependent on the type of oils.

Dry eye syndrome (DES) is a prevalent ocular condition characterized by tear film instability, inflammation, and discomfort, affecting millions worldwide. DES is related to oxidative stress imbalance and ocular surface inflammation, which are important factors in the development of the condition. Recent studies have demonstrated that fish oil, lutein, and zeaxanthin possess anti-inflammatory and antioxidant properties.

Omega-3 fatty acids are critical components of cell membranes, including those in the retina. Specifically, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are the primary omega-3 fatty acids that have been studied for their potential benefits in retinal health, preventing the progression of retinopathy. Several studies have shown that a higher intake of omega-3 fatty acids is associated with a lower risk of developing diabetic retinopathy and age-related macular degeneration (AMD).

Carotenoids are a diverse group of pigments imparting red, orange, and yellow hues to many horticultural plants, also enhancing their nutritional properties and health benefits. In strawberry, the genetic and molecular mechanisms regulating the natural variation of fruit carotenoid composition remain largely unexplored. In this study, we use a population segregating in yellow/white flesh to detect a major quantitative trait locus (QTL), qYellow Flesh-4B, located on chromosome 4B and accounting for 82% of total phenotypic variation.

Background: Carotenoids are well-established for their potent antioxidant properties; however, their potential association with severe headaches or migraines remains largely unexamined. This study was conducted to explore the relationship between serum carotenoid levels and the prevalence of severe headaches or migraines within the US population.
Methods: We utilized data from the 2001-2004 National Health and Nutrition Examination Survey (NHANES), which comprised a total of 8,910 participants.

Nature has been acknowledged as a fundamental source of diverse bioactive molecules. Among natural carotenoids, lutein, zeaxanthin, and their oxidative metabolites are specifically deposited in the macular region of living organisms. Lutein and zeaxanthin are carotenoids primarily found in green leafy vegetables, eggs, and various fruits.
