An egg a day for
breakfast probably won't increase your likelihood of developing type 2
diabetes, according to a new study.
In the study, researchers failed to see a significant association between
eating eggs occasionally or almost daily and the development of type 2
diabetes in nearly 4,000 older men and women.
While eggs are a key source of dietary cholesterol, they also contain a
number of other potentially beneficial nutrients. To figure out the net
effects of egg consumption as a whole food on type 2 diabetes risk,
researchers looked at 3,898 Americans participating in the Cardiovascular
Health Study. All were at least 65 years old when they enrolled in the
study. During follow-up, which averaged about 11 years, 313 people developed
type 2 diabetes, which is closely linked to being overweight as well as poor
diet and lack of exercise.
No relationship was found between any amount of egg consumption and
increased risk of type 2 diabetes. No link was found between dietary
cholesterol overall and diabetes risk. While men in the top category of egg
consumption, those eating eggs almost daily, were at increased type 2
diabetes risk, this increase wasn't statistically significant, meaning it
could have been due to chance.
Other studies that have linked eggs to diabetes have found an association
with very high consumption, generally for eating seven or more eggs a week.
On average, participants in this study ate less than one egg a day, so there
may not have been enough people with very high egg intakes to establish
whether this was harmful.
The current findings donít back any significant relationship between egg
consumption and type 2 diabetes.
