Going Beyond Muscle Building with Whey Protein
In addition to building muscle and boosting antioxidant levels in healthy people, whey protein might be the best supplement today for liver and immune health!So Much More from Whey
When you get to the topic of whey protein, you receive much more than simply increased muscle mass—for those seeking immune or liver health support in particular, the whey protein story gets especially exciting.It’s well documented that whey supplementation and proper exercise helps the body to lose fat and retain or build lean muscle. The latest study was published in the August 4, 2009 online edition of Clinical Nutrition and looked at patients with recent hip fractures. It showed that whey increases insulin-like growth factor (IGF-I) by nearly 30 percent in elderly hip fracture patients. IGF-I is necessary for stimulating muscle and bone growth and repair and is associated with human growth hormone levels.
Whey Bests Soy and Casein Proteins in Recent Study
So many new studies have come out in support of whey protein over other protein sources. One of the most exciting recent studies matched whey against casein and soy isolate, two other common sources of protein. Whey left its competitors in the dust.The September 2009 Journal of Applied Physiology compared whey with soy and casein and found it to be far superior for muscle synthesis. The study took place at McMaster University and was designed to compare the acute response of mixed muscle protein synthesis (MPS) to rapidly absorbed protein powders both at rest and after exercise. Three groups of healthy young men performed leg resistance exercise followed by the consumption of a drink containing whey protein, casein or soy protein isolate.
The differences were enormous. Amazingly, the MPS after consumption of whey was approximately 93 percent greater than casein and approximately 18 percent greater than soy. “A similar result was observed after exercise (whey > soy > casein); MPS following whey consumption was approximately 122 percent greater than casein and 31 percent greater than soy. MPS was also greater with soy consumption at rest (64 percent) and following resistance exercise (69 percent) compared with casein.”
Strengthening Immune Health
Shoppers might not realize whey is rich in immunoglobulins, protein molecules called bioactive peptides, that play a role in your body’s immune defense. Whey has a fabulous ability to raise antioxidant activity throughout the body. This is important for all of us but especially for select population groups, as we will share in a moment.Glutathione (GSH), one of the body’s primary antioxidants, protects your liver and other organs; it also helps your white blood cells to proliferate and to do their job. A few select supplements have been shown to elevate glutathione levels. Whey, however, might be best of all, as reported in the February 2001 issue of the European Journal of Nutrition, “Supplementation with whey proteins persistently increased plasma glutathione levels in patients…” In September 2007, the International Journal of Food Science and Nutrition, reported that among 18 healthy men and 18 healthy women over a two-week period, “Whey protein supplementation of 45 g/day for 2 weeks can increase lymphocyte GSH by 24%.”
Attention, Liver Health Patients more Good Antioxidant News
The June 2009 issue of the Journal of Gastroenterology and Hepatology reports that whey is critical for liver health patients. Many people have fatty inflammatory liver disease due to obesity, diabetes, environmental toxicity, alcohol abuse, or use of street and prescription drugs. They note glutathione depletion contributes to liver injury and development of steatohepatitis, otherwise known as inflammatory fatty liver.The following study evaluated the effect of oral supplementation with whey protein on patients with nonalcoholic steatohepatitis (NASH).
In an open-labeled clinical trial, 38 patients (18 male, 20 female) were given a daily dose of 20 grams whey protein isolate for 12 weeks. Researchers found that overall liver health improved with a significant reduction in previously elevated levels of liver enzymes coming to the conclusion, “Plasma glutathione and total antioxidant capacity increased significantly at the end of study… The results indicate that oral supplementation of cysteine-rich whey protein isolate leads to improvements in liver biochemistries, increased plasma GSH, total antioxidant capacity and reduced hepatic macrovesicular steatosis in NASH patients.”
Very Good for Your Heart
The July 2009 issue of Nutrition Journal reports whey protein is also a source of bioactive peptides and helps improve the vascular endothelial response of healthy individuals by supporting nitric oxide production, which helps to relax blood vessels. This could help people to maintain healthy blood pressure.At the 11th International Congress on Cardiovascular Pharmacotherapy (held in 2002 by the International Society of Cardiovascular Pharmacotherapy, May 18-21 in Montreal, Quebec, Canada) researchers reported that whey supplements resulted in a significant reduction in blood pressure levels by the end of the first week of treatment. This effect was maintained throughout the study. Treatment significantly reduced acetycholinesterase (ACE) activity while ACE activity remained mostly unchanged by the control protein. “In our study, hydrolyzed whey proteins significantly reduce BP, likely by altering ACE activity and bradykinin levels,” concluded the team. A 5 mm Hg decrease in blood pressure has been equated with a 16 percent decrease in heart disease, the leading cause of death globally.
These great studies are just the beginning of the vast health benefits from whey. It truly is a super food. So how do you get the best?
How to Find a Quality Whey Supplement
Finding a quality whey supplement doesn’t have to be difficult. Metabolic Response Modifiers (MRM) has made it their mission to produce the highest quality supplements on earth.First, let’s look at their standards. They combine ultra-filtered, low temperature processed whey protein concentrate with crossflow microfiltered whey protein isolate. These specialized processing systems provide a High Biological Value (HBV) whey supplement in the form of short and long chain peptides to increase protein retention. Their whey is remarkably high in branched chain amino acids (BCAAs), including leucine, the most necessary for maintaining metabolic rate (energy) especially during dieting or periods in between meals. In addition, so many protein supplements either don’t taste very good or use artificial flavors or sweeteners among other additives. MRM’s products come by their great taste using quality all natural ingredients with no added sugar. They offer pure whey in vanilla and chocolate; however, they continue to match their exceptionally high quality whey with other health promoting partners. You get to pick and choose which formulas serves your needs—and this is where their approach becomes so unique.
Here are their two latest:
Fruit-N-Whey™ delivers over 3500 ORAC units per serving of natural potent antioxidants, plus BCAA-rich whey protein in a delicious mix great for the blender or shaker.Most of us have an increasingly hectic lifestyle, which makes meeting nutritional needs more and more difficult. Getting the recommended daily amount of fruits is vital to providing your body with potent antioxidants to counteract free radicals and prevent the damage they inevitably produce. Equally important is maintaining proper protein intake throughout the day to maintain optimal metabolic function.
Everyday stress, environmental pollutants, natural metabolic processes and exercise generate different types of free radicals. MRM’s BeneFruit Blend combines the vitality of 10 fruits all known to be packed with an assortment of antioxidants to provide a broad spectrum of antioxidant protection. The Oxygen Radical Absorbance Capacity (ORAC) assay demonstrates the total antioxidant power of a sample, with the U.S. Department of Agriculture recommending a daily intake between 3,000 and 5,000 units.
Flax-N-Whey™ should also be worked into the mix because it provides both whey and omega-3 fatty acids. The key ingredient Flax3™ contains a gently processed, solublized flax meal combined with an ultra-refined stabilized source of marine omega-3 fatty acids to deliver a robust matrix of 36 mg of EPA and DHA combined with 540 mg of ALA from flax per serving. Stability of these essential fats is maintained by an array of natural antioxidants found in flaxseed which act synergistically to protect these precious oils. Flax3™ contains large amounts of phytoestrogens, known as lignans, which provide tremendous estrogen balancing support. This is a great supplement since everyone should be obtaining omega-3s from both marine and terrestrial sources such as flax.
Making whey protein part of your diet is a great way to maintain your overall antioxidant levels and health while building lean muscle and maintaining good circulatory and heart function—all of this from a most amazing supplement.
