Celiac disease and performance -

The brain's influence over physical performance is substantial. While Brady's diet limits many sources of gluten by default due to its focus on avoiding processed foods, refined grains, and sugars, it's not entirely accurate to label his diet as purely "gluten-free.

Novak Djokovic, the renowned tennis player, has been vocal about his switch to a gluten-free diet and how it profoundly impacted his health and tennis career.

In , Djokovic suffered from frequent bouts of fatigue, breathing difficulties, and a lack of stamina on the court. He consulted with Dr. Igor Cetojevic, who suspected that Djokovic might have a food intolerance. After undergoing tests, it was revealed that Djokovic was sensitive to gluten.

Based on this revelation, he made significant dietary changes. Here are some key points Novak Djokovic has made regarding his transition to a gluten-free diet:. The gluten-free trend, like many dietary movements, offers potential benefits but should be approached with caution and knowledge.

While there's no substantial evidence to suggest that a gluten-free diet will boost athletic performance in those without gluten-related conditions, individual experiences vary widely.

Athletes should prioritize listening to their bodies, staying informed, and seeking expert advice when considering significant dietary changes. After all, performance is not just about diet but a combination of training, mindset, recovery, and nutrition working together.

FITNESS Gluten-Free and Athletic Performance: Is There a Connection? Nov 9, By Robyn Kellin. What is Gluten? What is Celiac Disease? Gluten-Free and Athletic Performance: The Rationale Many athletes, both professional and amateur, believe that adopting a gluten-free diet can enhance their performance.

The reasoning behind this belief often includes: Reduced Inflammation: Gluten is believed by some to cause inflammation in the body. Inflammation can be detrimental to recovery and performance, and by removing gluten, athletes hope to reduce this inflammatory response.

Improved Digestive Health: Athletes with undiagnosed gluten sensitivities may experience bloating, gas, and other gastrointestinal symptoms. Adopting a gluten-free diet can alleviate these symptoms, leading to a more comfortable and optimized performance.

Pooled estimates were 0. Results of 7 studies, including 1 in primary care, showed fairly homogenous results for the diagnostic performance of IgA-tTG Table 4.

Sensitivity analysis excluding studies with a high risk of verification bias showed similar estimates, although the positive LR was lower Given a mean prevalence of 5. Only 3 studies analyzed diagnostic performance of IgG-tTG antibodies. In contrast, the study by Yagil et al 39 in a primary care population reported very good results, but showed verification bias because patients with negative serological results did not undergo further testing and were assumed not to have celiac disease.

Diagnostic performance of test combinations are presented in eTable 2. As expected, sensitivity decreased and specificity increased when combinations of positive serum antibody test results were required to diagnose celiac disease. Optimal results were achieved by combining a positive IgA-tTG and a positive EmA test result, with a sensitivity of 0.

Our review demonstrates widely varying results of diagnostic performance of presenting gastrointestinal symptoms in the identification of celiac disease.

Evaluation of serological tests showed good performance of IgA-tTG and EmA, but there was wide variation in sensitivity and specificity of IgA-AGA, IgG-tTG, and IgG-AGA. Serological tests have been extensively studied, and our results confirm those of previous reviews.

The drawback of primary care research is that not all participants can receive an invasive reference test, and the 3 primary care studies in this review 25 , 27 , 39 showed verification bias with only patients having positive test results going on to receive small-bowel biopsy.

Sensitivity analyses, however, did not show large effects of verification bias on pooled estimates of diagnostic parameters. The spectrum of disease and population characteristics are important determinants of diagnostic performance, and the prevalence of disease is a good indicator of this effect.

Lower positive predictive values imply more false-positive test results, and thus, possibly more unnecessary testing, which is an important concern in primary care. Characteristics of index and reference tests may also influence diagnostic performance.

Several test characteristics varied across studies, such as the definition of symptoms eg, for abdominal pain or diarrhea , criteria for a positive serological test, testing for IgA deficiency, tissues used for serological tests human, monkey, or guinea pig , and diagnostic criteria of celiac disease.

Cutoffs used for serological tests varied, but there was no clear association with sensitivity or specificity Table 4. Characteristics of serological testing, including reliability and observer agreement, may vary across locations and laboratories, possibly leading to differences in performance.

The presence of positive serum antibodies has been shown to correlate with the degree of villous atrophy, and patients with celiac disease who have less severe histological damage may have seronegative findings. In addition to patients with a positive family history of celiac disease, patients with longstanding or refractory abdominal symptoms may be more likely candidates for screening, and several case-finding studies appear to confirm this.

So which diagnostic strategy should be recommended? Our review shows that gastrointestinal symptoms alone are not sufficiently accurate. Some serological tests IgA-tTG and EmA showed good performance, but not one single serological test seems to be sufficient to identify all cases of celiac disease.

The EmA may have better test performance, but sensitivity was poor in some studies, and the test is more expensive, complex, and operator-dependent, with larger interobserver variation.

Given the strong dependence of diagnostic performance on prevalence and spectrum of disease, the effectiveness of a sequential strategy should be investigated in a primary care setting. Future research may also include a diagnostic randomized trial comparing the costs of different diagnostic strategies and their effects on treatment decisions and subsequent patient outcomes, including symptoms and signs, quality of life, and the consequences of false-negative and false-positive test results.

Strengths of this review include the use of current methods for searching evidence, quality assessment, and meta-analysis. The review was limited to cohort studies and nested case-control designs, discarding information from many case-control studies.

This increased the validity and clinical relevance of our findings because cohort studies provide more valid estimates of diagnostic accuracy in clinical settings. Although subgroup analyses seemed to indicate that study design did not explain variation in diagnostic performance, the number of studies was small, limiting the power of these subgroup analyses.

Pooled estimates were only calculated for studies showing sufficient clinical and statistical homogeneity. I 2 or Q tests commonly used in meta-analysis are not recommended for assessing statistical homogeneity in diagnostic reviews 48 because they do not take into account the association between sensitivity and specificity.

The sensitivity analyses for verification bias showed consistent estimates, which may indicate that the pooled estimates of sensitivity and specificity for these 2 tests were robust.

Further methodological development is needed to provide clear guidelines for assessing statistical homogeneity in diagnostic meta-analysis.

The population of interest was adults presenting with abdominal symptoms, but celiac disease may present with a wide range of other atypical symptoms.

For optimal identification of all patients with celiac disease, diagnostic testing should be considered in patients presenting with other symptoms or health conditions in which the prevalence of celiac disease may be high, such as iron-deficiency anemia, infertility, type 1 diabetes, Down syndrome, and reduced bone density.

In conclusion, in adult patients presenting with chronic abdominal symptoms, symptoms alone are insufficient for diagnosing celiac disease.

The IgA-tTG and EmA tests show good performance, but the evidence in primary care populations is limited. Further research should investigate the performance of a diagnostic algorithm, using sequential serological testing in patients with chronic or refractory abdominal symptoms in primary care.

A wheat allergy can be diagnosed with skin or blood tests. When a wheat allergy is present, one must avoid wheat, but can eat other sources of gluten. However, in contrast to CD, a non-celiac gluten sensitivity is characterized by negative antibodies and a lack of intestinal damage.

While it has been debated, experts currently believe there are no biomarkers that can consistently and accurately diagnose non-celiac gluten sensitivity. Thus, if CD and wheat allergy have been ruled out, trying a gluten-free diet can provide clues.

If symptoms improve, a non-celiac gluten sensitivity can be assumed. An emerging school of thought is that certain short-chain carbohydrates are poorly digested in the small intestine, causing bacterial fermentation and gastrointestinal symptoms.

Collectively, these short-chain carbohydrates are called Fermentable Oligo-, Di-, and Mono-saccharides and Polyols FODMAPs. While many foods contain FODMAPs, wheat is a rich source of fructans, one category of FODMAPs. Thus, it is possible that in the absence of CD, wheat products may cause intestinal symptoms due to poor digestion and bacterial fermentation of the carbohydrates present in wheat, rather than because of an immune response to gluten.

There are several factors to consider when discussing why a gluten-free diet can result in improved performance among athletes. The same goes for an athlete who falls within the estimated six percent of the population with non-celiac gluten sensitivity. If a gluten-free diet eliminates those symptoms, better performance is likely to result.

Similarly, if an athlete is consuming a large amount of wheat products, which is typical in the U. An athlete may also be experiencing improved performance with a gluten-free diet because it spurs an overall healthier eating plan. These additives are often used as thickeners, sweeteners, or fillers.

When gluten is eliminated, the athlete must stop eating many of these foods and find alternatives. Thus, when an athlete consumes cereal, bread, pasta, or crackers made from these grains instead of refined grains, nutritional intake is improved. When these foods are combined with others that are naturally gluten-free, such as fruits, vegetables, lean proteins, nuts, and seeds, the diet is extremely rich in nutrients.

Finally, when an athlete is interested in improving performance through dietary changes, their entire diet receives greater attention. In the process of learning about a gluten-free diet, they spend more time planning and preparing healthy meals, reading nutrition labels for sources of added sugar and salt, and eating more fruits and vegetables.

In general, this often leads to the development of fueling strategies that support better training, performance, and recovery. In other words, gluten-containing grains are not required for optimal health.

However, potential problems could arise if gluten-free dietary changes are not carried out carefully and thoughtfully. For example, carbohydrate intake must continue to be adequate. Most athletes require six to 10 grams of carbohydrates per kilogram of body weight on a daily basis.

Endurance athletes may need more during certain phases of training and competition. In addition to fruits, vegetables, and dairy, athletes depend heavily on grain products for carbohydrate.

If they do not regularly consume enough gluten-free grains, then their total carbohydrate intake may decline, resulting in glycogen depletion, fatigue, and poor performance. A gluten-free diet must also include good food choices. While unprocessed gluten-free products are available, there are also many highly processed, refined gluten-free foods.

The same is true for many types of candy and snack foods. Some types of gluten-free bread consist mainly of white rice flour and cornstarch, which are both poor nutrient sources. A variety of gluten-free cakes and cookies have also entered the marketplace. While they are wonderful for a special occasion, they are no healthier than their gluten-containing counterparts.

In addition, when an athlete embarks on a gluten-free diet, they are faced with the challenge of finding substitutes for their favorite foods. Many grocery stores are increasing their gluten-free offerings, but some may not have a wide selection. While the taste and variety of gluten-free products have improved dramatically in recent years, some of the new foods will seem different in flavor, texture, and appearance.

And some gluten-free foods can be significantly more expensive, creating additional challenges, especially for college athletes. Perhaps the most profound problem with attempting a gluten-free diet is that it could potentially delay the proper diagnosis of CD or another medical condition.

While fatigue, headaches, bloating, constipation, diarrhea, abdominal pain, skin rashes, muscle pain, and joint pain have all been associated with CD and sometimes non-celiac gluten sensitivity, these symptoms have also been connected to many other medical conditions.
