When a child performs poorly at school, parents often blame lack of effort, too much screen time or poor teaching. However, one often overlooked factor may be the child’s gut health.
Children who frequently suffer from bloating, excessive gas, constipation or tummy discomfort may also experience headaches, tiredness, irritability and difficulty concentrating in class. Scientists are finding growing evidence that the gut and the brain are closely connected.
The digestive system contains trillions of microorganisms known as the gut microbiome. These organisms help digest food, support immunity and produce substances that influence mood, sleep, attention and memory. When the balance of these microorganisms is disturbed, a condition known as dysbiosis may occur.
One important cause of dysbiosis is the regular consumption of highly refined foods. These include soft drinks, sweets, biscuits, cakes, white bread, crisps, instant noodles and many packaged snacks. While such foods provide calories, they contain very little fibre which is essential for feeding beneficial gut bacteria.
A diet low in fibre may reduce the number of helpful bacteria and allow less desirable microbes to flourish. This imbalance can contribute to bloating, constipation and inflammation. Some studies suggest that poor gut health may also affect concentration, behaviour and learning.
Parents can help by encouraging children to eat more natural foods such as beans, peas, lentils, fruits, vegetables, whole grains, nuts and seeds. These foods provide fibre and nutrients that support a healthy gut microbiome. Drinking enough water, getting adequate sleep and engaging in regular physical activity are also important.
Of course, learning difficulties have many causes and a bloated tummy is not always responsible. However, when a child frequently complains of stomach discomfort, headaches or constipation, parents should not ignore these symptoms. Improving gut health may benefit both the body and the mind.
As research continues to explore the gut-brain connection, one message is becoming clear: A healthy gut may help children feel better, think better and learn better.
