(NaturalHealth365) Whey protein, already beloved by athletes and bodybuilders for its ability to build lean muscle and support fat loss, has another health-promoting trick up its sleeve. According to just-published research, whey protein can actually help prevent obese people from developing diabetes and heart disease.
With over a third of all American adults and close to a fifth of American children currently diagnosed as obese – putting them at risk for heart disease and diabetes – this is significant news indeed. Not to mention the value of whey protein for millions of people deprived of high-quality protein.
Whey protein balances blood sugar and lowers fatty deposits in the blood
In a Danish study conducted at University of Copenhagen and published in the latest issue of Journal of Proteome Research, researchers explored ways in which different protein sources affect metabolism. Volunteers were divided into four equal groups and all were given high-fat meals of soup and bread, but each group’s meal also featured one of four different types of protein: whey isolate, casein – another milk protein – cod, a cold water fish, or gluten.
The team found that volunteers who ate the whey protein meal had lower amounts of fat in their bloodstream, along with increased amounts of insulin, which clears glucose from the blood and regulates sugar levels. They also experienced more complete absorption of the protein, and had slower emptying of their stomachs. In contrast, those who ate the gluten meal had elevated numbers of hydroxyl fatty acids.
And that’s not all – whey protein helps alleviate high blood pressure
Cutting levels of fatty acids in the bloodstream is not the only way that this milk protein combats heart disease. In 2010, a study published in International Dairy Journal showed that when people with elevated blood pressure drank a daily beverage enriched with whey protein, their diastolic and systolic blood pressure came down by as much as 6 points. The reduction began after about a week, and continued for the duration of the 6-week study.
Although a 6-point reduction may not sound very significant, scientists say that even this modest reduction can cut the risk of heart disease and fatal stroke by an impressive 35 to 40 percent. Whey protein can even reduce your risk of cancer.
Editor’s note: The NaturalHealth365 Store has a limited (monthly) supply of “Grazing Goat Whey Protein” – the cleanest, ethically-produced whey protein on the market. This goat whey comes from goats that graze 365 days per year on lush, chemical-free pastures; the whey is non-GMO, gluten-free, hypoallergenic and easily digestible.
Interestingly, the whey protein did not lower levels in those who have normal or low blood pressure – only those with elevated blood pressure were affected. It is almost as if the whey protein “knows” optimal blood pressure levels, and attempts to help the body achieve them.
Another plus for whey protein: with a complete lack of reported harm, toxicity or side effects, whey is safe to consume. It is also easily available and tends to be well-tolerated – especially for those suffering from past allergies to conventional (cow) dairy products.
What is whey protein, and where does it come from?
Whey protein is first isolated from whey – the liquid left behind when milk is processed into cheese – and then filtered to remove fats and carbohydrates. Before the nutritional benefits of whey were known, this fluid was routinely discarded – a complete waste of a great protein source. Roughly 20 percent of milk’s protein is found in whey, while casein – the substance that creates curds – accounts for the other 80 percent.
Whey protein has been shown to boost immunity
Thanks to its constituents, such as lactoferrin and lactalbumin, whey protein has potent antioxidant effects. In fact, whey protein, by providing ample quantities of the amino acid cysteine, helps to create antioxidants – especially the creation of glutathione, a powerful antioxidant that occurs naturally in the body.
Lactoferrin in whey protein also stimulates the immune system, activating natural killer cells; in addition, it acts as a powerful anti-inflammatory by inhibiting the inflammatory substance interleukin 6.
Researchers tell us that lactoferrin and other glycoproteins in whey also have antimicrobial effects that help combat disease-causing pathogens. As for whey protein’s blood pressure lowering abilities, researchers say the key lies in its antihypertensive peptides, which work as ACE inhibitors to block the conversion of vasoconstrictor molecules.
What type of whey protein should I use?
Whey protein is available in powdered form, often sold as flavored shakes and beverages. There are three main forms — whey protein concentrate, whey protein isolate and whey protein hydrolysate—to choose from.
Whey concentrate is the least filtered, and the most inexpensive of the three. Whey protein isolate, the form most commonly used in studies, undergoes longer filtering times. With whey hydrolysate, the whey has been extensively filtered, and the protein chains have been broken down into smaller peptides fragments. Unfortunately, most whey proteins have been highly-processed with too much heat – which destroys its nutritional value and the quality of the whey is questionable – especially when you consider that many farmers feed their animals GMOs.
So, with cancer, diabetes and heart disease taking a serious toll on the lives and health of so many people, it’s imperative to find safe, natural, food-based methods of prevention. High-quality whey protein provides an important ally in the effort to boost immunity,build physical strength and prevent disease.
Grazing Goat Whey Protein is available now. Please understand this is the finest quality, whey protein on the market. Best of all, this goat whey protein comes from goats that graze 365 days per year on pesticide and chemical-free pastures. No hormones, antibiotics or pesticides are used – ever.
