You probably know already that researchers have found quite a bit about the benefits of whey protein – including many significant health benefits. There is extremely good news available now about Whey Protein and Cholesterol. It has been conformed that Whey is a potent inhibitor of oxidized low density lipoprotein cholesterol (LDL Cholesterol). Even smaller amounts of Whey Protein seem to have the ability to fight the bad Cholesterol. The Whey ingredient “Lactoferrin” seems to be the key here. When the lactoferrin was removed from the protein, the ability of the whey-protein concentrate to prevent LDL oxidation was greatly reduced, leading researchers to the conclusion that, “Lactoferrin (LF) is the main factor responsible for the inhibitory effect of whey protein on LDL and may function synergistically with other factors in whey protein…”
Another research study examined the effects of whey protein concentrate and casein and the risk factors of what we commonly know as heart disease. Though casein (which is another milk-based protein) is actually known to raise cholesterol, whey protein has the opposite effect, leading researchers to note, “At high dietary protein ingestion levels, whey protein significantly lowered plasma and liver cholesterol and also plasma triacylglycerols.”
So, several studies have shown the positive affect Whey Protein can have when ingested by individuals that suffer from high cholesterol or have a family history of high cholesterol. As with everything that comes into play with high cholesterol, it is important to know that you will need to look at this issue long-term. One week of Protein intake will not be enough to lower your cholesterol on a continious basis. If you decide to use Whey Protein to lower your cholesterol, you should consider this a long-term thing and use it daily. Our recommendation is to buy Whey Protein in bulk for the money savings and to buy the right kind of Whey Protein for your situation.
