Athletes follow special diets for a variety of reasons. GF, vegetarian, and lean diets are some of the most common diets adopted for health, ethical, religious, and industrial purposes https://online-casinos-usa.net/. The prevalence of CD has increased dramatically, and GFD has become a popular approach to nutrition. A strict GFD for athletes with CD, WA, or GI will improve their health and may increase performance.
Grubic et al. developed a glucose-free food bar that meets sports nutrition guidelines. Ingestion of a bar containing whey protein (20 g), isomaltooligosaccharides of plant fibers (25 g), and fats (7 g) is effective in glucose homeostasis and performance, compared to the experience of conventional carbohydrate intake. Subjects were asked to take a food bar 30 min before, during, and after exercise during the study. The training program consisted of 11 resistance exercises (three sets of ten repetitions), followed by agility exercises and timed sprints. This study showed that the glycemic and insulinemic responses were more favorable for the maintenance of euglycemia than the intake of an equivalent amount of carbohydrates (dextrose) , which in turn allowed maintenance of the necessary level of performance during training and reduced muscle pain after exercise.
Dairy products are also in demand, as they are some of the best muscle-building aids in sports . However, athletes often experience lactose intolerance. In this case, milk must be replaced with products containing enzymes, such as fermented milk. The digestibility of such products reaches 91%, in contrast to the digestibility of milk, which is 34% .

Blends of protein sources might afford a favorable combination of key nutrients such as leucine, EAAs, bioactive peptides, and antioxidants, but more research is needed to determine their ideal composition.
Collectively, these results indicate that increasing dietary protein can promote favorable adaptations in body composition through the promotion of fat-free mass accretion when combined with a hyperenergetic diet and a heavy resistance training program and can also promote the loss of fat mass when higher intakes of daily protein (2-3× the RDA) are combined with an exercise program and a hypoenergetic diet.
For building muscle mass and for maintaining muscle mass through a positive muscle protein balance, an overall daily protein intake in the range of 1.4–2.0 g protein/kg body weight/day (g/kg/d) is sufficient for most exercising individuals, a value that falls in line within the Acceptable Macronutrient Distribution Range published by the Institute of Medicine for protein.
