Eggs not linked to cardiovascular risk, despite conflicting advice

University of Sydney researchers aim to help clear up conflicting dietary advice around egg consumption, as a new study finds eating up to 12 eggs per week for a year did not increase cardiovascular risk factors in people with pre-diabetes and type 2 diabetes.

Published in the American Journal of Clinical Nutrition today, the research extends on a previous study that found similar results over a period of three months.

Led by Dr Nick Fuller from the University’s Boden Institute of Obesity, Nutrition, Exercise and Eating Disorders at the Charles Perkins Centre, the research was conducted with the University of Sydney’s Sydney Medical School and the Royal Prince Alfred Hospital.

In the initial trial, participants aimed to maintain their weight while embarking on a high-egg (12 eggs per week) or low-egg (less than two eggs per week) diet, with no difference in cardiovascular risk markers identified at the end of three months.

The same participants then embarked on a weight loss diet for an additional three months, while continuing their high or low egg consumption. For a further six months – up to 12 months in total – participants were followed up by researchers and continued their high or low egg intake.

At all stages, both groups showed no adverse changes in cardiovascular risk markers and achieved equivalent weight loss – regardless of their level of egg consumption, Dr Fuller explained.
