What happens to your IGF-1 levels when you eat 2 eggs every day?

IGF-1 is perhaps the most powerful growth factor in the body when it comes to building bones and muscles. Your body manufactures more IGF-1 the more protein-rich foods are in your diet. Eggs in particular are effective IGF-1 boosters, Thai scientists discovered.


What happens to your IGF-1 levels when you eat 2 eggs every day?


Study
Researchers from Mahidol University conducted an experiment with 3 groups of students aged 8-14 for 35 weeks.

Students in the experimental group received 2 eggs every school day with their school lunch [WE]. [Thai schools provide students with lunch.] Students in another group were not given eggs for lunch, but an equivalent that provided the same amount of energy and protein [protein substitute; PE]. After all, students in the control group simply received a standard lunch and nothing else.

Results
Including eggs in the diet increased IGF-1 levels more than incorporating a protein substitute. Click on the figure below for a larger version.

The addition of eggs to the test subjects' diet increased the concentration of not all, but many short chain fatty acids. The researchers think that the microflora in the intestines plays a major role in this.

The researchers found a link between the increase in short chain fatty acids and the increase in IGF-1 levels. They raise the possibility that the increase in short chain fatty acids in the blood of the test subjects may have caused this increase in IGF-1 levels.

Growth hormone repairs joints, skin and other connective tissues. Some endocrinologists suspect that intensive exercise can slow down aging because exercise increases the production of growth hormone.
