News & Research:

  • Ideal protein to help seniors rebuild lost muscle - Science Daily, 10/10/18 - "Researchers found that protein did not stop lean muscle loss caused by inactivity, however, whey supplements helped to rebuild muscle once the participants activities resumed ... whey versus collagen protein ... Whey is considered a high-quality or complete protein, meaning it is rich in all essential amino acids and is higher in leucine, one of the essential amino acids the body cannot make itself and therefore, must derive from food ... Collagen peptides, by comparison, are much lower in their leucine content, lack or are low in essential amino acids ... While protein was ineffective in mitigating muscle loss, say researchers, when participants returned to normal, muscle-building activity, the whey group recovered more skeletal muscle" - See whey protein at Amazon.com and leucine products at Amazon.com.
  • Whey beneficially affects diabetes and cardiovascular disease risk factors in obese adults - Science Daily, 4/30/14 - "They gave volunteers who were obese and non-diabetic the same meal of soup and bread plus one kind of protein, either from whey, gluten, casein (another milk protein) or cod. The scientists found that the meal supplemented with whey caused the subjects' stomachs to empty slower than the others'. These subjects also had lower levels of fatty acids in their blood after meals but higher amounts of the specific types of amino acids that boost insulin levels"
  • Effects of Soy, Whey Protein Supplementation Post-Exercise - Science Daily, 10/12/13 - "Our main findings demonstrate that 14 days of supplementation with soy protein does appear to partially blunt serum testosterone. In addition, whey influences the response of cortisol following an acute bout of resistance exercise by blunting its increase during recovery"
  • Eating protein throughout the day preserves muscle and physical function in dieting postmenopausal women, study suggests - Science Daily, 8/10/11 - "higher protein intake during weight loss can offset negative effects on muscle mass by maintaining more muscle relative to the amount of weight lost. Women who ate more protein lost 3.9 percent more weight and had a relative gain of 5.8 percent more thigh muscle volume than woman who did not ... 31 healthy, postmenopausal obese women were divided into two groups. Each group followed a 1,400-calorie weight-loss diet based on USDA's My Pyramid, but one group received a powdered whey protein supplement in the morning and again in the afternoon or evening; the other received a placebo that contained carbohydrates ... We hypothesize that more vigorous exercise -- in particular, resistance training -- would preserve even more muscle" - See whey protein at Amazon.com or try the yogurt recipe at the top of my yogurt page.
  • Whey Protein May Be Helpful for Weight Loss - WebMD, 7/15/11 - "Researchers at the U.S. Department of Agriculture's Human Nutrition Research Center randomly assigned 90 overweight and obese middle-aged adults to one of three groups. The first group was asked to add protein drinks made with whey to their normal diets, the second group drank protein drinks made with soy protein, and the third group drank carbohydrate drinks ... the drinks, which were drunk twice daily, at breakfast and dinner, had the same number of calories: 200. They also all had had 52 grams per packet, for a daily total of 104 grams of added protein or carbs ... After six months, people drinking the carbohydrate shakes had gained a little bit of weight, about 2 pounds, which appeared to be mainly added fat ... People drinking the soy shakes had stayed about the same weight as where they started ... But people drinking the whey protein had lost a little bit of weight and body fat, about 2 pounds. Additionally, while the other groups saw little change in the size of their waists, the whey protein group lost about an inch around the middle ... a couple of things may help to explain the weight and fat loss seen with whey protein ... People in the whey protein group had significantly lower blood levels of the hormone ghrelin than people eating the soy protein or carbohydrate ... And though researchers really can't explain why this happened or what it means, they found that people drinking the whey protein had cut back on their carbohydrate intake by the end of the study, even though they weren't eating fewer total calories and didn't know what kind of supplement they were getting ... researchers advise picking a whey product that is also low in calories and fat"
  • Whey protein may cut metabolic risk of high-fat diet: Mouse study - Nutra USA, 3/24/11
  • Whey protein holds fat fighting potential, suggests study - Nutra USA, 2/3/11 - "The amount of fat inside liver cells (known as intra-hepatocellular lipid concentrations – IHCL) in subjects fed a short term high fat diet has been previously shown to be reduced again through increasing dietary protein intake ... four weeks of supplementation with whey protein led to a significant decrease in IHCL of 21 percent, whilst fasting plasma triglyceride was observed to decrease by 15 percent, and total plasma cholesterol concentration decreased by over 7 percent" - [Abstract]
  • Whey supplements lower blood pressure: Low-cost protein gets big results in people with elevated blood pressure - Science Daily, 12/8/10 - "Beverages supplemented by whey-based protein can significantly reduce elevated blood pressure, reducing the risk of stroke and heart disease ... daily doses of commonly available whey brought a more than six-point reduction in the average blood pressure of men and women with elevated systolic and diastolic blood pressures ... blood-pressure reductions like those seen by Fluegel can reduce cardiovascular disease and bring a 35 to 40 percent reduction in fatal strokes"
  • Whey protein better than meat for reducing body weight - Nutra USA, 6/7/04 - "Increasing the dietary density of whey protein, but not of red meat, reduced body weight gain by 4 per cent, they add, while whey protein also reduced plasma insulin concentration by 40 per cent and increased insulin sensitivity, compared to meat protein"
  • Athletes Believe The "Whey" To Greater Muscle Strength Is Through Training And Protein Supplements - Intelihealth, 4/10/03 - "supplementation with a100% whey isolate formulation and creatine produced greater muscle fiber growth increases that transferred into significant increases in functional strength"
  • The New Faces Of Whey - Life Extension Magazine, 1/02 - "whey may be able to reduce stress and depression by lowering cortisol and increasing brain serotonin, improve liver function (in those suffering from certain forms of hepatitis) and reduce blood pressure"
