Egg Protein Hydrolysate and Vascular Function
The Effect of Egg Protein Hydrolysate on Arterial Stiffness in Overweight or Moderately Obese Subjects With Impaired Glucose Tolerance or Diabetes Type 2
The incidence of type 2 diabetes mellitus (T2DM) is rapidly growing. Patients with T2DM are at increased risk of developing long term micro- and macrovascular complications. Subjects with impaired glucose tolerance (IGT) show increased blood glucose levels after an oral glucose load. These subjects have a markedly increased risk of later T2DM development.
T2DM development can be prevented or delayed by lifestyle modifications. To support lifestyle changes and reduce the risk of T2DM development, foods containing functional ingredients are being developed. An interesting functional ingredient is protein hydrolysate. An egg protein hydrolysate has been experimentally shown to improve endothelial function, to inhibit plasma angiotensin converting enzyme (ACE) and to reduce blood pressure in rats. Egg protein hydrolysate could thus be a interesting ingredient to treat the cardiovascular dysfunction associated with T2DM. In the present study, the effects of egg protein hydrolysate will be evaluated in subjects with overweight or moderate obesity and IGT or T2DM.

Intervention / Treatment |
---|---|
Experimental: intervention and placebo
Once in the study, 20 subjects will be randomly assigned to a group taking capsules containing 5 gr egg protein hydrolysate per day, and 20 to a group taking placebo capsules.
The subjects consume the capsules during three consecutive days (period 1).
Following a wash-out period of minimally four weeks, the treatments are crossed-over.
