Marathon Couple Promotes Healthy Eating in Kortrijk

Lisa Bos · 2026-04-26

When you think of marathon runners, you probably imagine elite athletes in sleek gear, not entrepreneurs juggling grocery chains. But Jeroen Demeersseman and Shalane Vandemaele, a power couple behind Delhaize, are proving that fueling your body right is a race everyone can win. They recently made headlines during the Marathon of Kortrijk, not just for crossing the finish line, but for championing a cause that hits close to home for many: healthy eating. It's a topic that's especially relevant for folks dealing with food allergies or sensitivities, where every bite feels like a gamble. ### Why This Matters for Your Health Here's the thing: what you eat directly impacts how you perform, whether you're running 26.2 miles or just trying to make it through a busy workday. The couple's message is simple but powerful: whole, unprocessed foods are your best bet. Think of it like this: your body is a high-performance engine. If you feed it low-grade fuel, don't expect it to run smoothly. For those with food allergies, this can be a challenge. But it's not impossible. You can still enjoy nutrient-dense meals that support your health without triggering reactions. The key is knowing what works for you. ### How to Eat Like a Marathoner (Even If You're Not One) You don't need to train for a marathon to benefit from better nutrition. Here are some practical tips inspired by the couple's approach: - **Prioritize whole foods:** Focus on fruits, vegetables, lean proteins, and whole grains. These are naturally free from many common allergens and packed with vitamins. - **Plan ahead:** Meal prep can save you from reaching for processed snacks when you're hungry. It's a game-changer for anyone with dietary restrictions. - **Listen to your body:** If you feel sluggish after eating something, take note. It might be a sign of an intolerance or allergy. ### The Role of Blood Testing in Nutrition This is where things get interesting. Many people don't realize that food allergies can fly under the radar. You might experience bloating, fatigue, or brain fog without connecting it to what's on your plate. That's where blood testing comes in. A simple test can identify triggers you never suspected. For instance, you might be reacting to dairy or gluten without knowing it. Once you identify these culprits, you can tailor your diet to avoid them. It's like having a roadmap for your health. ### Practical Steps to Get Started If you're curious about optimizing your diet, here's a straightforward plan: 1. **Keep a food diary:** Track what you eat and how you feel. Patterns will emerge. 2. **Consult a specialist:** A professional can help interpret test results and create a personalized plan. 3. **Start small:** Swap one processed item for a whole food each week. Small changes add up. Remember, you don't have to be perfect. The goal is progress, not perfection. Jeroen and Shalane didn't become health advocates overnight. They likely started with small steps, just like you can. ### Final Thoughts Healthy eating isn't about deprivation. It's about finding what makes you feel energized and alive. Whether you're running a marathon or just running errands, your body deserves quality fuel. And if you suspect food allergies are holding you back, consider getting tested. It could be the first step toward a healthier, happier you.
