Two articles from the same authors. They study development of 1) obesity and 2) cardiovascular disease after 12 years of follow-up and they relate them to the study baseline food choices.

Article 1

Two surveys 12 years apart. Prospective observational study.

«We found that a low intake of dairy fat was associated with a higher risk of developing central obesity and that a high intake of dairy fat was associated with a lower risk of central obesity among men without central obesity at baseline» (see).

Article 2

Two surveys 12 years apart. Prospective observational study.

«Daily fruit and vegetables consumption was associated with a lower risk of coronary heart disease only when combined with a high intake of dairy fat. Low intake of dairy fat, choosing mostly wholemeal bread or eating fish at least twice a week was not associated with a reduced risk of coronary heart disease in this cohort of rural middle-aged men». (see)

 

Table: Death or hospitalization owing to coronary heart disease during 12 years of follow-up according to food choices reported at baseline, adjusted analyses (N = 1,663).

 

Conclusions

These studies are observational so we are not allowed to conclusions of causality. Nevertheless, I wouldn’t say dairy fat causes obesity nor cardiovascular disease.
