Important factors regarding food choices vary according to lifestyle preferences . People may choose to play sports to become physically active. Motivation for this can be to maintain or improve health, the desire to have a lean body, and optimal weight https://jackedwebdesign.com. Several studies have shown that performance is one of the most important factors affecting food choice for athletes, both for individual and team sports . In addition, an athlete’s attention regarding choice of nutrition may vary depending on the phase of the season, the type of sport, the fitness of the athlete, and the level of competition . For example, when training performance is not particularly critical, hockey players in the off-season are more relaxed about food choices, while more competitive triathletes tend to prefer food that maximizes performance. Strength athletes place less emphasis on performance factors (e.g., nutrient content in foods) than endurance athletes . It is important to keep these points in mind when working with athletes.
Diet composition can also be determined by the social factors associated with daily life . For example, one’s schedule of work, school, training, competition, or other amusement can determine food choice, while preference is given to food that can be quickly and easily prepared . It is also important for athletes to meet their energy needs after exercise, so they may have frequent consumption of food that is convenient and easy to prepare . Some athletes report overeating in dining rooms due to the abundance of options available and/or repeated trips to the grocery line after observing teammates eating . Similarly, the dietary choices of younger athletes can be influenced by the dietary choices of older and more experienced teammates . Food marketing, media, and advertising are common sources of nutritional information for many consumers, including athletes, and this can influence their food choices .
The most common are gluten-free (GF), vegetarian, and lean diets. These diets are popular diets for the entire population, however, they are also used by some professional athletes to maintain health. An increasingly popular diet low in FODMAPs is used to reduce exercise-related gastrointestinal symptoms . However, the potential consequences of dietary restrictions and special diets should be carefully evaluated .

Filtration methods differ, and there are both benefits and disadvantages to each. The two most popular methods of filtration of a given protein are the use of ion exchange and micro/ultrafiltration methods. Ion exchange exposes a given protein source, such as whey, to hydrochloric acid and sodium hydroxide, thereby producing an electric charge on the proteins that can be used to separate them from lactose and fat . The advantage of this method is that it is relatively cheap and produces the highest protein concentration . The disadvantage is that ion exchange filtration typically denatures some of the valuable immune-boosting, anti-carcinogenic peptides found in whey . Cross-flow microfiltration, and ultra-micro filtration are based on the premise that the molecular weight of whey protein is greater than lactose, and use 1 and 0.25-μm ceramic membranes, respectively, to separate the two. As a result, whey protein is trapped in the membranes but the lactose and other components pass through. The advantage is that these processes do not denature valuable proteins and peptides found in whey, so the protein itself is deemed to be of higher quality . The main disadvantage is that this filtration process is typically costlier than the ion exchange method.
