Conversely, combined allele frequencies did not significantly predict how healthy or attractive females were rated by the opposite sex (Health: F1,36 = 0.175, R2 = 0.005, p = 0.678; attractiveness: F1,34 = 2.421, R2 = 0.066, p = 0. 129; Table 2).
Each facial photograph was rated for the following perceived traits: healthy, dominant, knowledgeable, sociable, attractiveness, and babyfaceness.
Previous work has demonstrated that oxygenated blood colour makes faces appear healthier [32], and facial attractiveness is often based on cues of health [42].
SST holds that in order to maximize the number of healthy offspring, men are primarily driven by the attractiveness of a potential mate, since attractiveness is assumed to be an indicator of "good genes" in terms of good health and high reproductive value (Barber, 1995; Gangestad, Thornhill, & Yeo, 1994; Thornhill & Grammer, 1999).
But when it comes to motivation to eat well and keep healthy, caring about esthetics, good looks and attractiveness are major incentives.
They rated the faces for attractiveness (very unattractive to very attractive), health (very sick to very healthy), and tiredness (not at all tired to very tired) on a 100 mm visual analogue scale.
The "good genes" explanation of attractiveness posits that mate preferences favour healthy individuals due to direct and indirect benefits associated with the selection of a healthy mate.
These factors were affordability, travel convenience, car parking, hygiene-food safety, service, variety, availability of local/traditional foods, store attractiveness, promotions- sales-coupons, and healthy foods.
There were a large number of outcome variables in the stimulus evaluation test due to the use of two different ratings (liking and attractiveness), three different categories of food images (healthy-go, high-energy density-no-go and novel foods) and two time points (baseline and post-intervention).
For a tan... for that 'nice healthy glow' society has come to associate with vigor and attractiveness.
