Whey proteins may possibly inhibit the angiotensin converting enzyme (ACE). I'm sure you've heard of the class of blood pressure lowering drugs called ACE inhibitors that do the same thing. A combination of whey peptides in whey powder may possibly support healthy blood pressure levels already within normal range. Other cofactors in whey may possibly reduce the stickiness of blood platelets and the risk of thrombosis, which can trigger both heart attack and stroke. Because science has greatly helped us understand the nourishing benefits of healthy fats we know the consumption of grass-fed whey protein may also help to support healthy lipid levels.
In addition to minerals necessary for bone growth, whey contains a protein called lactoferrin, which may be associated with a wide range of benefits including supporting a healthy immune and inflammatory response. Research has now determined that lactoferrin may support the body's ability to support healthy bone, which could possibly have a positive impact on the long term effects of osteoporosis and non-healing bone fractures.
Prebiotics are foods or compounds that are fermented by bacteria in the colon after they've entered the system. You can either supply your colon with additional beneficial bacteria through the use of probiotics, or you can feed the beneficial bacteria already present with specific compounds to help them multiply in number and become more dominant. When used in combination with a good probiotic, whey proteins and its other components act as a prebiotic to provide added assurance that your "second immune system" (your gut) is getting the help it needs.
