Do Exercise and a Gluten-Free Diet Go Hand in Hand
Going gluten-free has gained popularity as a diet trend among many people, including an increasing number of athletes. In actuality, 41% of athletes say they consume no gluten at least 50% of the time. However, due to conditions like gluten sensitivity, wheat allergies, or celiac disease, only 5 to 10% of the population is thought to have clinical aversions of gluten. Because of this, a large proportion of athletes consume no gluten while not having a documented medical diagnosis.
The assumption that a gluten-free diet increases performance, lowers fatigue, promotes mental well-being, and helps lessen inflammation lies among just a few of the reasons why athletes might undertake this dietary shift. The main justification for this adjustment, according to sportsmen, is to prevent gastrointestinal discomfort when exercising.
A significant issue in sports endurance, which is gastrointestinal distress, occurs in 15–30% of participants. When competitors must stop to use the restroom or otherwise continue the competition while feeling uncomfortable, their time trial performance obviously suffers. In fact, even stomach discomfort itself lowers endurance performance.
Although there is ample evidence that avoiding gluten reduces gastrointestinal problems in clinical populations, it is less clear if this advantage holds true for people who do not exhibit clinically discernible gluten aversions. Nevertheless, 84% of sportsmen who limit gluten in their regimens to increase performance say they feel a difference. This raises the issue of whether or not athletes should follow a gluten-free diet.
What Is Gluten, and Why Might Cutting It Out of Your Diet Improve Your Athletic Performance?
A protein called gluten is present in wheat as well as other grain-based foods. The most likely advantage of eliminating gluten is to lessen gastrointestinal problems that occur in people who are gluten sensitive after exercise. Not all of the components of the broken-down gluten are easily absorbed through the stomach wall and into the blood system. They may act to attract water into the intestines and cause diarrhea and cramps during exercise because they are osmotically reactive (may modify water movement inside the body).
High-intensity activity (such as of professional athletes on whose performances they rely themselves, as well as their teams and bettors at bookmaker-expert.com/country/papua-new-guinea causes the digestive system’s blood flow to be diverted, which leads to inadequate oxygenation and inflammation. Exercise is a period when the digestive system is particularly susceptible since this inflammation increases the absorption of the stomach. In this way, after consuming a large amount of gluten in their food, some people may develop gastrointestinal issues when exercising, but this process is yet speculative.
Could Avoiding Gluten Affect How Well You Perform in Sports?
It can be extremely challenging to discover foods that do not include any gluten whatsoever because gluten is so common in the products we consume. For this reason, if athletes are unable to eat the foods that are readily available to them, it may be difficult for them to effectively feed themselves for activity and ensure a healthy recovery. A gluten-free athlete won’t be able to stay up with the competition if avoiding gluten causes overload and/or shortened training adaptations as a result of insufficient calorie intake, regardless of whether it really causes gastrointestinal issues.
A gluten-free diet raises the risk of iron, fiber, and deficiency of the following types of B vitamins: B1, B2, and B3. It can also cost 242% more than a conventional diet that provides an equivalent number of calories. As a result, someone who follows a gluten-free diet needs to be careful to appropriately fuel their exercise.
What Is the Conclusion?
In a randomized controlled trial, 13 healthy volunteers followed a gluten-free diet for seven days while completing an endurance time trial assignment. The study was published in the Journal of Science and Medicine in Sport in December 2015. The same subjects repeated testing 10 days after the test and swapped snacks to one they had not had in 7 days. There were no differences between the times when athletes consumed gluten-free or gluten-containing diets in regards to time trial performance, gastrointestinal symptoms, subjective emotions of well-being, or signs of intestinal injury.
Therefore, it appears that a gluten-free diet is neither helpful nor harmful as long as athletes eat enough and successfully address vitamin deficits.
What Nutrition Should You Ensure That You Intake if You Decide to Stop Eating Gluten?
The most frequent dietary deficiency that develops when consuming a gluten-free diet is a lack of iron, fiber, and B vitamins (B1, B2, and B3).
These frequently-missed nutrients can be found in the following gluten-free foods:
- B vitamins: beans, potatoes, and squash (B1); meat milk, almonds, soy nuts, milk, and yogurt (B2); and fish poultry, dairy, mushrooms, beans, and peanuts (B3).
- Iron: turkey, beef, tuna, oysters, legumes, and soybeans.
- Fiber: broccoli, sweet potatoes, corn, legumes, and beans.
The Lesson
A gluten-free diet should not be adopted in order to increase athletic performance; it should only be done out of personal preference. In people without gluten sensitivity, following a gluten-free diet has neither negative nor positive effects on gastrointestinal symptoms nor performance outcomes. There is a significant asterisk, though.
Another dietary component that has been shown to have an impact on performance is frequently eliminated from gluten-free diets. This information may aid in understanding why many sportsmen restrict gluten to a certain extent because they feel it helps them perform better. It is a group of sugars with short chains (short-chain carbohydrates) that are not properly absorbed in the gut called FODMAP (an abbreviation for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols). However, FODMAP requires a separate article and approach to find out why it may help to explain the alleged advantages of a gluten-free diet.
