Short sleepers tended to eat less vitamin C, tap water and selenium (found in nuts, meat and shellfish) consumption, but more lutein or zeaxanthin, which are found in green, leafy veggies.
The latest part of the study, which involved about 4, 000 participants, also looked at the effect of replacing beta-carotene in the supplements formulation with lutein and zeaxanthin because of studies that found former smokers who take beta-carotene have a higher incidence of lung cancer.
