Dietary supplements and physical activity: Food intolerance in sport really exists. 2021 http://ezaposleni.singidunum.ac.rs/rest/sciNaucniRezultati/oai/record/1/8993 T. Stojmenović M. Kostić Vučićević D. Michalickova M. Andjelković I. Nikolić N. Dikić Aim: Food intolerance an be the cause of many different health problems. It is known that 5%-20% of humans have a food intolerance, but it stays unrecognized in many cases because of nonspecific symptoms. Otherwise, moderate physical activity has a lot of positive effects on immunity and people’s health generally. But very intensive training, as in professional athletes, has a bad influence on immunity, such as increasing gastrointestinal barrier (GI) permeability and leading to food intolerance. Many studies show the presence of high sensitivity to food intolerance in professional athletes. It is apparent that extreme physical activity is one of the risk factors. The aim of this study was to examine the influence of a 3-month elimination diet on specific IgG antibodies level, GI discomfort intensity, body composition, and sports performance of the athletes. Methods: This was an experimental longitudinal study in the duration of 3 months. 32 professional athletes participated: 18 males (mean ± SD; mean age 25±7 years) and14 females (mean age 25±4 years). The participants were professional athletes, with training more than 10 hours per week. They were chosen on results of The Allergy Questionnaire for Athletes (AQUA) and Gastrointestinal Symptom Rating Scale (GSRS)questionnaires, and, results of specific IgG food intolerance blood test. All athletes were on a 3-month elimination diet based on a particular specific IgG food intolerance blood test results. In addition to the above questionnaires and specific IgG food intolerance blood test, basic medical examinations with sit and reach test of flexibility and cardiopulmonary testing were assessed before and after the study. Results: AQUA scores were significantly lowered (p = 0.001). There was a significant reduction in total GSRS score (p = 0.049) and indigestion syndrome score (p = 0.017). The level of the specific IgG antibodies significantly decreased for all athletes and all foods they were intolerant to. The fat percent (FAT%) decreased significantly (p= 0.001) without change in weight (p= 0.13). Heart rate (HR) at the second (p= 0.03) and the third minute (p = 0.01) recovery phase was significantly lower. The flexibility of athletes significantly increased (p = 0.001). Conclusions: The results indicate a positive effect of a 3-month elimination diet based on IgG food intolerance blood test on GI discomfort, in terms of the significant decrease in its intensity and a significant improvement in athletes’ body composition and sports performance. conferenceObject 53 53 14th INTERNATIONAL CONGRESS ON NUTRITION: „A PLACE WHERE SCIENCE MEETS PRACTICE“
