The role and development of the immune system

The immune system plays a key role in protecting the body against various infections and diseases. In infancy, the immune system is still in its early stages of development, and its effectiveness is strongly influenced by external factors, including nutrition, environment, and exposure to illnesses.
Supporting the immune system is especially important for babies. In the following video, Dr. Tibor Kovács, a pediatric specialist, shares useful advice on how to properly support your baby’s immune system.

What are the most important immune boosters?

Vitamin D, often referred to as the “sunshine vitamin”, plays a vital role not only in bone development but also in immune system function. A deficiency can lead to weakened immunity and increased susceptibility to infections. The primary natural source is sunlight, but during winter months, supplementation in drop form is necessary for infants—this is mandatory, so never forget it!

Vitamin C (Ascorbic Acid) is a water-soluble vitamin with strong antioxidant properties. It helps protect cells from harmful free radicals and is essential for proper immune function. It also enhances white blood cell production, which plays a crucial role in fighting infections. During the fall and winter seasons, supplementing with vitamin C drops is recommended, especially when babies start attending daycare or nursery school.

Probiotics also play a significant role in strengthening the immune system. The gut is one of the body’s most important immune organs, with lymph nodes in the intestinal walls actively involved in immune responses. Billions of beneficial bacteria in the gut are essential for this process. Antibiotic treatments can eliminate not only harmful bacteria but also these essential beneficial gut bacteria. Therefore, taking probiotics during and after antibiotic treatments is often recommended to restore gut flora balance.

Antioxidants also support immune function. These include vitamins C, E, and A, as well as flavonoids. Additionally, omega-3 fatty acids and certain trace elements, such as selenium and zinc, are crucial. Adequate iron intake is also essential, as anemic children are more prone to infections. Moreover, balanced protein intake—neither too much nor too little—is important for overall immune health.

 

How does nutrition affect immune function?

A balanced diet, rich in vitamins, minerals, and antioxidants, plays a significant role in strengthening the immune system and enhancing the body’s defense against infections.
Healthy eating habits, including a diet high in fruits, vegetables, whole grains, and lean proteins, are essential for optimal immune function. On the other hand, excessive sugar and fat intake can weaken the immune system, making it important to limit these foods in a child’s diet.

 

 

Are breastfed babies healthier?

Breast milk plays a crucial role in infant nutrition, and numerous studies confirm that breastfed babies tend to be healthier. It contains essential nutrients that support healthy growth and strengthen the immune system.

Breast milk is rich in natural immune-boosting components, such as antibodies, which help protect infants from infections and diseases. Additionally, it provides vitamins, minerals, and essential fatty acids that contribute to overall well-being. In general, breastfed babies get sick less often and recover more quickly from illnesses.

 

How does the environment contribute to strengthening the immune system?
It is fascinating how environmental factors play a significant role in immune system development. Research has shown that allergies and illnesses are much less common in children who grow up in less sanitized and overprotected environments. Kids who live in rural areas or farms often develop a stronger immune system and are more resistant to allergies and diseases than those who are excessively shielded from external factors.

 

Early exposure to animals and outdoor play in natural environments helps strengthen the immune system. Parents shouldn’t worry if their child crawls on the floor, eats without perfectly clean hands, or plays outside and interacts with different elements. These everyday experiences help stimulate the immune system, allowing it to develop properly and function more effectively.

The development of the immune system is a long process that cannot be rushed. When a child enters a community setting, it is inevitable that they will encounter various illnesses, and these cannot always be prevented. However, certain methods, such as vitamin supplementation and a healthy, varied diet, can help shorten the duration of illnesses.
The foundation of acquired immunity is that the body encounters different infections and pathogens, gradually building protection against them over time.

 

 

Preventing infections between siblings

When an older sibling attends daycare or school, they are often exposed to infections, which can easily be brought home. It is important to take precautions to protect the younger sibling. During an illness, it is advisable to separate siblings as much as possible to reduce the risk of transmission.
The concern is not just that the younger child will eventually get sick, but that infections can be more severe for infants due to their smaller anatomical size. For example, a simple cold can cause more significant issues for a baby due to their narrow nasal passages, as difficulty in breathing through the nose can be more problematic for them than for an older child.

Although complete separation may not always be feasible, and younger siblings will inevitably encounter some pathogens, by the time they enter a community setting themselves, they will have already been exposed to certain infections, allowing their immune system to better protect them.

 

Why should sick children be kept out of daycare or school?

It is crucial not to bring sick children into a community setting. While some believe that mildly ill children can still attend, arguing that their immune system will naturally fight off the infection, this is not always the case.
A sick child’s bodily fluids can spread infections to others, and some children may be more vulnerable to certain illnesses, leading to more serious complications. A simple cold can escalate into severe conditions such as croup, asthmatic bronchitis, or middle ear infections in susceptible children.

 

 

Summer illnesses and the importance of fresh vegetables

The summer season provides an excellent opportunity to consume a variety of fresh vegetables and fruits, ensuring a sufficient intake of essential vitamins and minerals. This is particularly important for strengthening the immune system.
Experience shows that fewer illnesses occur during the summer months. One reason for this is that attendance in community settings decreases, reducing the spread of infections. Additionally, higher temperatures and frequent ventilation help limit the spread of airborne pathogens. Lower humidity levels and fresh air also contribute to fewer cases of illness among children.

Strengthening a baby’s immune system is a multifaceted task that relies on vitamins, a balanced diet, and the right environmental factors. Breast milk, fresh vegetables and fruits, and proper vitamin supplementation all contribute to healthy development and better resistance to illnesses.
Finally, don’t forget that good hygiene habits and preventing the spread of infections in daycare and school settings are also essential for maintaining children’s health!
