Nutrition knowledge, attitudes and fat intake: application of the theory of reasoned action


AFRC Institute of Food Research, Earley Gate, White-knights Road, Reading RG6 ZEF, UK.


Validated questionnaires eliciting information on nutrition knowledge and attitudes, related to fat intake from meat, meat products, dairy products and fried foods, were completed by 538 subjects. There were high correlations (ranging from 0.40 to 0.77) between the sums of belief-evaluations, attitudes, intention and self-reported behaviour, with similar correlations for a subgroup of males aged 35–54 years. Nutrition knowledge, showed some statistically significant (but small) negative correlations with components of attitudes. Females had higher nutrition knowledge scores and more negative views of the foods than did males. Fat intake, measured using %day weighed intakes, correlated with self-reported behaviour (r = 0.55, P <0.01) in a subsample of 30 males, aged 35–54 years. Thus, nutrition knowledge seems less clearly related to consumption of these foods than are more specific beliefs and attitudes.
