Most triathletes know that excess sugar and alcohol aren’t ideal for performance or health, but there are healthy foods that can wreak havoc on people’s digestive systemMelissa Piercell is a Toronto-based Naturopathic Doctor who shed some light on how to navigate dietary restrictions. If you’re eating a well-balanced diet and feeling good, keep doing what you’re doing, but if you need a reset, she recommends foods to try ditching for a couple of weeks.

Piercell says, “If you know you’re not feeling right but can’t nail down what’s making you feel like garbage, there are a few keys foods athletes can eliminate to see if they feel better. And when you’re eliminating these foods, make sure you really eliminate them otherwise you won’t know if they’re causing the problem.” She recommends a three week elimination period before reintroducing the eliminated food.

Piercell explains that six of the major allergens are dairy, gluten, soy, caffeine, alcohol and processed sugar. These allergens, if poorly accepted, can cause inflammation in the digestive tract. Alcohol is inflammatory for everyone, but other foods vary from person to person. Piercell says, “You will likely feel pretty good if you eliminate all of these foods, but it’s very restrictive. I wouldn’t recommend trying something like this around a big training block or key competition date.”

On top of the six major allergens, there are several foods that can cause inflammation that aren’t as well known. Nightshade vegetables, which include tomatoes, peppers, eggplants and potatoes, are all very nutrient dense foods but also foods that don’t agree with everyone. “If you’re having joint pain, these foods are something to consider eliminating as they have been shown to increase inflammation in that area.” Other nutrient-rich foods to consider ditching if you’re not feeling 100 per cent are nuts, such as peanuts and almonds, and red meat.

Piercell concludes, “Should all athletes stop eating these foods? No. These are just examples of foods that are commonly consumed that can be an unsuspected cause of inflammation.”
