Whey is the liquid released from separated milk products such cheese or thick yogurt.
Whey protein has been shown to have effects on immune regulation, decreasing the stimulation of white blood cell production in the face of allergens. Whey protein is considered insulinotropic, causing an increased release of insulin; type 2 diabetics should be aware of this when accounting for insulin levels.
Whey should be avoided by anyone who is lactose intolerant, as it may cause intestinal distress.
