Family resemblance in beliefs, attitudes and intentions towards the consumption of 20 foods that contribute to the fat intake was investigated in 97 adult women, their mothers and their grandmothers. Mean correlation for elements from the Fishbein and Ajzen theory of reasoned action between younger and middle generations ranged from 0.09 to 0.17 and between middle and older generations from 0.12 to 0.17. All significant correlations were positive. More statistically significant correlations were found for liking attitudes between the younger and middle generations (p < 0.05 for ten out of 20 correlations) than for other pairs. Between the older and younger generation the number of significant correlations could be due to chance alone. From the relative importance of liking and good/bad attitude on intention it appeared that liking contributed the most to the variance in intention scores. Health related beliefs and attitudes became of increasing importance in the older generations. From this study it can be concluded that mothers and their adult daughters resemble each other in beliefs, food preferences, attitudes and intentions, although resemblance is poor.
