Sarcopenia affects a slice of the population that is growing, and fast. By the year 2050, the world’s population of people aged 60 years and over is expected to triple. The growing elderly population, and the indications that protein intake may be linked to preserving muscle mass and strength, it’s easy to see how there could be a prominent place for protein in the healthy-aging market. High-protein diets have also been found to be associated with reduced instances of sarcopenia in older adults. The current recommended dietary allowance (RDA) of protein is 0.8 g per kg of body weight, and studies have suggested that almost 40% of people over the age of 70 fail to meet this level of protein intake. This creates a significant opportunity to develop convenient, tasty, and healthy food and drink products that help seniors get more high-quality protein into their diet and prevent or even slow down the development of sarcopenia.
Whey Protein can be separated from the casein in milk or formed as a by-product of cheese making. Whey Protein is the protein contained in whey, the watery portion of milk that separates from the curds when making cheese. Whey Protein is considered a complete protein and contains all 9 essential amino acids and is low in lactose content. People commonly use it as supplementation, alongside resistance exercise, to help improve muscle protein synthesis and promote the growth of lean tissue mass. Whey Protein are now being transferred to the healthy-aging market from sports market. Whey protein ingestion is an effective nutritional strategy to combat the age-related loss of muscle mass, strength, and function known as sarcopenia. Whey protein has been shown to stimulate muscle protein synthesis (MPS) to a greater extent than casein and soy protein at rest and following exercise in young and older individuals. Powering up diets with more high-quality proteins, such as whey protein, spreading that protein intake throughout the day, and exercising more regularly are three simple steps for maintaining, and even increasing, muscle mass in older adults.
