"The taste is sweet and mild and it's also free of food allergens." While plant proteins continue to make inroads, the variety of dairy proteins available to meal replacement formulations also has advanced. Cow milk contains fats, sugars (e.g., lactose) and both whey and casein proteins. Milk protein concentrate (MPC) contains the same ratio of proteins found in cow milk, including both whey and micellar casein. Milk protein isolate (MPI) contains higher protein content than MPC. Casein, in micellar form, is another top form of dairy protein and is known to block muscle protein catabolism, the breakdown of proteins. Casein is considered the slower absorbing of the two, releasing its amino acids over a longer period of time. Thus, casein may be more ideal for meal replacement products for times, such as in the evening, when protein absorption will have longer to be digested and utilized— while sleeping, for instance. Conversely, whey protein is a fast-acting form of protein used to quickly increase muscle protein synthesis (MPS), the process of building muscles. Whey contains all the essential amino acids (must be ingested via the diet), including BCAAs, and it has a higher percentage of BCAAs than casein. Whey isolate and whey concentrate are both derived from simple whey protein. Whey protein contains numerous biologically active compounds, including various peptides and polypeptides, as well as fats and carbs. Whey concentrate ramps up whey's moderate protein content—from around 35 percent to around 75 percent—and reduces the fat and carb content. Concentrate still contains the growth factors immunoglobulins and other immunoactive compounds of whey, as well as phospholipids and key weight management lipids such as conjugated linoleic acid (CLA). Whey isolate uses multiple fi ltration steps to remove more fats and carbs (lactose), resulting in a higher protein content (90 to 95 percent). This is a good whey type for lactose-intolerant consumers and those strictly counting carbs. Isolate can also be made via ion exchange, which may yield the highest protein-containing whey, but it sacrifi ces most or all of the other biologically active immune compounds in the process. Immune benefi ts are one of the key reasons why probiotics are another trend in meal replacements. In addition to digestive benefi ts, probiotics can help boost immune function tied to the gut. Intense exercise can depress immune function. Spore- forming probiotics such as Bacillus coagulans have become popular in bars and beverages due to an ability to remain inherently protected until they release their inner bacteria in the right place in the gut. The fi ber trend plays into the addition of probiotics, as several specialty fi bers serve as food for benefi cial bacteria. Oligosaccharides and inulin (from chicory root) are popular prebiotics, but pectin, resistant starch and arabinogalactan are other common prebiotics. Regional Performance North America, Europe and Asia Pacifi c are the top regions for meal replacement sales. According to Euromonitor International's analysis, emerging markets in Asia Pacifi c and Eastern Europe have contributed the most to meal replacement worldwide growth from 2010 to 2015, due to companies' investments in those regions. On the other hand, growth in America was fl at during the same period, which was also the case in Australia. Still, Technavio noted the Americas region accou nts for the largest share (about 55 percent) of the global meal replacement market, and future growth leading into 2020 in this region will be driven by the increasing aging population and associated health conditions, as well as by a rising awareness of proactive health care. In the United States, plant protein made big gains in the meal replacement market, with 27 percent annual growth in 2015, according to SPINS. The retail consumer insights fi rm reported pea protein isolate was a dominant plant protein due to being a grain-free and hypoallergenic source of lysine, arginine and BCAAs. Echoing Jaeger's sentiments, meal replacements combining multiple types of plant proteins have been growing well in the U.S. market, more than doubling in sales to reach $18 million in 2015 (SPINS). Emerging plant protein sources experiencing growth included cranberry, artichoke and sacha inchi (Incan peanut, from Peru). SPINS also reported meal replacement manufacturers moved to better compete with the whole food movement by incorporating fruit and vegetable phytonutrients into formulations. Richard Kreider, Ph.D., a Texas A&M University researcher, highlighted several fruit and vegetable ingredients as part of a session on emerging sports nutrition ingredients at the 2016 SupplySide West trade show. He noted a lack of antioxidants in athletes can lead to excessive free radicals and oxidative stress that contribute to muscle damage, infl ammation, suppressed immune function and prolonged recovery. Due to several challenges with consuming the right types and amount of antioxidant-rich fruits and vegetables, concentrates and juices are popular with athletes and other sports nutrition consumers, he noted. Montmorency tart cherries, pumpkin seeds, grape seeds, betaine (spinach and beets) and quercetin—a fl avonoid found in onions, apples, berries, tea, grapes and red wine—were among the fruits and vegetables highlighted by Kreider as researched for antioxidant and/or anti-infl ammatory benefi ts to athletes.
