In March 2019 researchers from the USA published the results of their study to assess the association of dietary cholesterol or egg consumption with cardiovascular disease (fatal and non-fatal coronary heart disease, stroke, heart failure, and other deaths due to cardiovascular disease). Information on diet was self-reported. 29,615 participants (average age 52 years, 45% male) were followed up for an average 17.5 years during which time there were 5,400 cardiovascular events and 6,132 all-cause deaths. Results showed that each additional 300 mg of dietary cholesterol or additional half an egg consumed per day was significantly associated with a higher risk of cardiovascular disease and all-cause mortality. However, the association between egg consumption and cardiovascular disease and all-cause mortality did not appear to be significant after taking into account dietary cholesterol consumption.
