MPCs are complete dairy proteins that contain both casein and whey proteins. MPCs with higher concentrations of proteins can be used to enhance a products protein content without adding significant levels of lactose and contribute valuable minerals such as calcium, magnesium, and phosphorus in the Best Absorbable form. The Amino Acid profile. Used By Many Nutitional Products For The Time Bound Release of Energy. For optimal health, evidence shows Americans may need more protein than previously thought. Protein is the major structural component of all cells in the body and functions in the form of enzymes, transport carriers, and hormones. The body requires a steady supply of the nine essential amino acids from dietary protein to synthesize new proteins and balance the rate of protein breakdown. The Recommended Dietary Allowance (RDA) for protein, 0.8 g/kg of body weight per day for those aged 19 and older, is based on the minimal amount of protein required to prevent protein deficiency, not necessarily the optimal amount to promote health. The Institute of Medicines Acceptable Macronutrient Distribution Range (AMDR) for protein goes from 0.8 to at least 2.5 g/kg of body weight per day (or 10% to 35% of total calories from protein). Since protein needs are a function of lean tissue mass, not calorie intake, protein requirements should be calculated in terms of body weight rather than as a percentage of calories. This is critical with lower energy intakes: When calorie intake is low and protein needs are calculated as a percentage of calories, the amount of protein may be inadequate. Moreover, when energy needs arent met, protein becomes an alternate fuel source, which may increase. Recent research shows that protein intake at levels above the RDA but within the AMDR may help achieve and maintain a healthful body weight by increasing satiety and thermogenesis (the energy required to digest, absorb, and dispose of the nutrients from food), and improving body composition, and it can play a role in the treatment and prevention of obesity, osteoporosis, type 2 diabetes, heart disease, and sarcopenia.2, 6 One study found better weight maintenance and fat reductions in moderately obese subjects who consumed a low-fat, high-protein diet containing either casein or whey following a weight-loss program compared with a low-fat, high-carbohydrate diet.
