The adjusted risk of heart failure over nine years declined 26% for women who reported a monthly chocolate intake of one to three servings and by 32% for those who said they ate one or two servings per week. Both findings were significant. The analysis was based on over 30,000 members of the Swedish Mammography Cohort.
The authors also found, however, that eating 1 or more servings of chocolate per day caused the protective benefits to be lost.
