Fit through the year: How a healthy gut can ward off infections

Runny noses, coughing fits and tired children’s eyes: one cold often follows another in the fall and winter, especially during daycare and school time. As parents, you’ve no doubt often wondered how you can strengthen your children’s immune system. Surprisingly, the answer often lies in the gut, or more precisely in the intestines. This is where a large part of our body’s immune system is located.

The defense center in the abdomen

The intestine is much more than a digestive organ! It is also a kind of training camp for the body’s defenses. Around 70% of all immune cells are located here! Countless substances enter the body with every meal, every sip and even through our hands. The gut has to decide at lightning speed: harmless or dangerous? This is the only way to maintain balance. When immune cells in the gut encounter new bacteria or viruses, they learn to recognize them and can thus protect the whole body.

Cold loop or strong defenses?

Many parents are familiar with it: as soon as one cold is over, the next one is just around the corner and often affects the whole family. Sometimes this is simply due to the normal exchange of viruses at nursery and school, which the child’s immune system cannot fully combat. A weakened gut can increase the risk of infections occurring more frequently and more severely. If the intestinal flora, i.e. the interaction of the “good” bacteria, is out of balance, pathogens have an easier time of it. A healthy gut, on the other hand, acts like a protective shield. It not only supports the immune system in its defense, but also helps to avoid unnecessary inflammation.

Vaccination & gut: a strong team

It is also exciting that intestinal health is linked to vaccinations. This is because the many bacteria in the gut are in constant communication with the immune cells. They send small signals that help the body to build up a strong immune response. If the intestinal flora is out of balance, this response can be somewhat weaker. However, this does not mean that vaccinations would not work without a “healthy” gut. They are and remain an important form of protection. It just shows how closely the gut and the immune system are linked.

What parents can do specifically

The best thing is that as parents you can do a lot to support your children’s gut and therefore their immune system:

  • Fiber on your plate: fruit, vegetables, wholegrain products and pulses feed the good bacteria in your gut
  • Don’t forget fermented foods: Yogurt, kefir or sauerkraut provide living microorganisms that enrich the intestinal flora
  • Drink, drink, drink: water and unsweetened teas help to keep everything flowing smoothly
  • Exercise & sleep: they also have a positive effect on intestinal health and thus on the immune system

Strong bellies, strong kids

A healthy gut is much more than just a “digestive aid”. It is the heart of our immune system and can determine how often children fall ill or how strongly their bodies fight off infections. If you support your child’s gut with the right diet and a healthy lifestyle, you will not only ensure less tummy rumbling, but also more energy and a strong immune system throughout the year!

Eating for gut health doesn’t have to be complicated: With fiber-rich foods, colorful vegetables, whole grains and yogurt, the intestinal flora can be strengthened – delicious and integrated into everyday life in a child-friendly way.
