Egg intake & metabolic syndrome
B etter health with eggs
Linked with the risk of developing cardiovascular disease and diabetes, metabolic syndrome is a clustering of at least three of five of the following medical conditions: abdominal (central) obesity, elevated blood pressure, elevated fasting plasma glucose, high serum triglycerides and low high-density lipoprotein (HDL) 'good cholesterol' levels.
The public has long been advised to limit egg consumption, despite little evidence of any harmful effect of eggs on blood cholesterol. This study evaluated the potential association between egg consumption and metabolic syndrome (Mets) in adults. A total of 2 887 subjects were recruited from 2005 to 2009. After excluding subjects who had Mets at baseline, 1 663 subjects were followed for an average of 3.2 years.
During the follow-up period, Mets occurred in 289 subjects. Consuming more than 3 eggs per week was significantly associated with decreased risk of Mets in both men and women compared to non-users. There was an inverse relationship between egg consumption and abdominal obesity in men and women. Also, higher egg consumption in men was associated with a decreased risk of high fasting blood glucose and high triglycerides.
These findings add to the body of evidence that advise on egg intake should focus on recommending egg intake as part of a healthy diet as opposed to the old view of restricting egg intake in healthy middle-aged and elderly people.¡
