Skin tone is a telltale sign of health, and what you see in the mirror reflects your diet and environment. Together, our results suggest that carotenoid-based coloration may have been sexually selected in humans, but we have no evidence to suggest that it is an honest signal of health.

The bottles were randomly assigned and coded by a research assistant who was not involved in the study. Perceived health contributes to the attractiveness of facial symmetry, averageness, and sexual dimorphism, Carotenoid intake does no affect immune-stimulated oxidative burst in greenfinches. DC M Markers of DNA oxidation (8-OHdG) and lipid peroxidation (isoprostane) were analyzed in duplicates using competitive enzyme-linked immunoassay (ELISA) kits from Northwest Life Science Specialties (Vancouver, VA). S Lee Lindström . Contrary to the carotenoid trade-off hypothesis, we did not find any effect of beta-carotene on measures of oxidative stress, immune function, semen quality, or sperm DNA fragmentation. Meylan Hau Perrett Chinese deem reasonable in Siberia :D.

Costantini and Møller (2008) conducted a meta-analytic review and concluded that there is little evidence that carotenoids function as antioxidants in birds. All variables are presented as pre–post difference scores (indicated by Δ) with the exception of the 2-alternative forced-choice attractiveness and perceived health scores, which were scored based on the percentage of times the post-supplementation face of a participant was chosen as more attractive or healthy looking, respectively, and the sperm DNA fragmentation levels, which was measured post-supplementation. We also had a placebo group consisting of an additional 20 male participants. Our study provides the first evidence for a causal link between beta-carotene and these changes.
