The study compared margarine and butter consumption on 832 men age 45-64 years and free of heart disease, with over 21 years of follow-up.
The study found that:
(a) For each increment of 1 teaspoon per day of margarine there was a 10% increase of heart disease over 21 years.
(b) Butter intake did not predict heart disease incidence.
Gillman concluded that the study offered support to the hypothesis that margarine intake increases the risk of coronary heart disease.
