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.

S Lee Lindström .

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.
