Nutrition Tips for a Strong Immune System

Nutrition Tips for a Strong Immune System


Which Foods Are Especially Important


We all know that a healthy diet strengthens our well-being and boosts our energy. But did you also know how crucial the right foods are for a strong immune system? From my active time as a professional football player – and even now as a former player – I know how important it is to provide the body with the best possible care so that it stays in top shape and fends off infections.

Over the course of my career, I learned a lot about nutrition. It wasn't just about improving performance, but also about strengthening the immune system. I’d like to share with you a few of my personal tips that anyone – whether athlete or not – can easily implement.

1. Vitamin C Suppliers: The Immune Boosters on Your Plate


You’ve surely heard it many times before: Vitamin C is one of the most important vitamins for the immune system. For me, it was always a must to get enough of it, especially during the stressful phases of the season. I liked to reach for kiwis, citrus fruits, bell peppers, and berries. These foods not only kept me fit, but they also taste fantastic – a real win for daily nutrition. A fresh fruit salad or smoothie is quickly made and provides you with the necessary Vitamin C, which can support your immune defenses.


2. Healthy Fats: Omega-3 as a Secret Weapon


During my active career, I often paid attention to the right mix of fats. Omega-3 fatty acids, which you can find in fatty fish like salmon or plant-based sources like flaxseed oil and walnuts, are real health wonders. They help reduce inflammation, thus supporting your immune system. For example, I regularly included fish in my diet. If you don't like fish, just try chia seeds or flaxseeds. These small powerhouses can be wonderfully integrated into muesli or yogurt.



3. Colorful Vegetables: The More Colorful, The Better


One of the secrets I've learned over the years is how crucial colorful vegetables are for our health. They not only provide many vitamins and minerals but can also help strengthen the immune system.
Especially green leafy vegetables like spinach or kale are true nutrient powerhouses. I always remind myself: The more colorful the plate, the better! Carrots, tomatoes, beets – all these vegetables are rich in antioxidants and can help you stay healthy and fit.


4. Fermented Foods: The Underestimated Power of the Gut


One aspect that many underestimate is the importance of a healthy gut flora. When your gut is doing well, your immune system benefits as well. In my career, I have often relied on yogurt, kefir, or sauerkraut. These foods contain valuable probiotic bacteria that promote gut health. Especially during stressful times, I have made sure to support my body with these foods. A well-functioning gut can be the key to fewer infections and faster recovery.


5. Proteins: Building Blocks for a Strong Immune System


No matter if during training or on the field – proteins have always been essential for me to build muscle and recover. But proteins can also be crucial for a strong immune system. They are the building blocks of our body and support the production of antibodies. I regularly eat high-quality protein sources like legumes, eggs, lean meat, and nuts. Even a simple scrambled egg or a handful of almonds in between can help your body stay strong and respond faster to attacks from viruses and bacteria.


6. Spices and Herbs: Small Helpers with a Big Impact


What many people don't know: Spices also have a significant impact on health. In my kitchen, turmeric and ginger are always a staple, especially when it comes to preventing inflammation. Both spices have strong anti-inflammatory properties and can naturally support the immune system. A turmeric-rich tea or a splash of ginger in a smoothie can make a real difference. A simple but effective tip.


7. Water and Tea: Don't Forget to Stay Hydrated


Last but not least: Drinking enough is essential for supporting the immune system. I always made sure to drink plenty of water not only during the game but also to stay hydrated throughout the day. In football, we used to have the formula: "1% loss of water equals 10% loss of performance." Water helps flush toxins from the body and provides nutrients to the cells. Additionally, I often relied on green tea, which I still enjoy drinking a lot today. It is rich in antioxidants and can further support the immune system. So it doesn’t always have to be just water – tea offers a delicious alternative that also promotes well-being.


Nutrition plays a key role when it comes to health and the immune system. As an athlete, I have realized that a balanced and mindful diet makes a difference. Often, it is the small adjustments that can have a big impact – just give it a try. Have fun with it.

Stay strong and healthy!
