Although we tend to think of the digestive system as solely responsible for processing food, in reality, it is also a key player in our body’s defence. Here we explore how these two systems work together to protect us.
A shield in your gut
The digestive system not only breaks down food, but is also home to millions of micro-organisms that form the gut microbiota. This community of bacteria helps strengthen our defences by training the immune system to differentiate between dangerous pathogens and beneficial allies.
The role of the immune system
Seventy per cent of our immune cells are found in the gut. Their job is to detect and neutralise any threats, without attacking the good microbes that help us digest and absorb nutrients.
Food and defence
According to several studies, proper nutrition plays a crucial role in the prevention and treatment of infectious diseases by influencing the interaction between the gut microbiota and the immune system.
A balanced diet rich in fibre, probiotics and prebiotics is key to maintaining a healthy microbiota and, with it, a strong immune system. Foods such as yoghurt, kefir, fruit, vegetables and pulses promote optimal microbial balance.
In addition, it is essential to incorporate minerals such as zinc, selenium and iron, along with essential vitamins such as A, C, D and E, which contribute to a well-functioning immune system.
In addition, habits such as good hydration, stress management, regular exercise and adequate rest are essential to maintain the balance between the digestive and immune systems. Practicing proper hygiene and avoiding infections also contribute to this natural defence.
Adopting these habits will contribute to a strong and balanced digestive and immune system.
Take care of your health from the gut and strengthen your defences!
