As for the visual assessment, the researchers indicated that lutein and zeaxanthin are carried in the blood by lipoproteins and "deposited in the retina, where they form, together with mesozeaxanthin, the macular pigment, which acts as a blue light filter and can be considered a marker of long-term dietary exposure. This macular pigment then increases with lutein and zeaxanthin supplementation and is associated with improvements in contrast sensitivity and visual performance, which is dependent on dose in healthy participants and in participants with impaired vision
For HFD feeding, the mice were maintained on a HFD (D12492) (60.0 % kcal from fat) (Research Diets Inc., New Brunswick, NJ, USA) starting at 8 weeks of age unless stated otherwise

Pups were anesthetized with isoflurane 12% mixed with warm compressed air/oxygen for the MRS scans, then placed on a MR compatible, heated animal bed (temperature maintained at 38.0 0.2 C) connected to an animal monitoring unit (SA Instruments, Inc., Stony Brook, NY), which recorded respirations, pulse oximetry, and core temperature
Once ingested, B12 requires intrinsic factora glycoprotein produced by gastric parietal cellsto facilitate absorption in the terminal ileum
