Why am I writing today the article “How to Strengthen Your Child’s Immunity for Autumn?”
It is summer outside, we are all thinking about the sea and carefree holidays, but autumn is not far away.
For years now, August 1 has been a very special day because I know that right then, despite the summer mood and nice weather, is the right time to start getting healthy for the fall.
That is why today, on some of the hottest days, I am following my mission to support families to take care of their health.
With the onset of autumn and the return of children to school, strengthening children’s immunity becomes a priority for every parent. But unfortunately, after the first illness already in the midst of the autumn-winter period, it is much more difficult to support immunity, because the process takes time. The fall season brings with it an increased risk of colds and flu, and with the right and timely approach, we can prepare our children’s bodies to handle these challenges. The perfect time to start fall care is in the summer!
In this article, we will look at how through natural superfoods and healthy habits we can build strong defenses for our children.
How to Strengthen Your Child’s Immunity for Autumn?
1. Healthy digestive system
A healthy digestive system is the foundation of strong immunity. Probiotics play a key role in maintaining the balance of gut flora, which is closely linked to our immune system.

Bifidus
Bifidus, also known as Bifidobacterium, is a genus of gram-positive, anaerobic bacteria that are a key component of a healthy gut microbiota. Here are some important aspects of Bifidus:
Research: Intensive research is ongoing on the potential of Bifidus to prevent and treat a variety of health conditions, including allergies, obesity and even some neurodegenerative diseases.
Natural environment:Bifidus bacteria are among the first microorganisms to colonise the digestive system of newborns. They are particularly abundant in the large intestine.
Health benefits:
Improve digestion and nutrient absorption
Strengthen the immune system
Produce B vitamins and vitamin K
Reduce the risk of diarrhea and other gastrointestinal problems
May relieve symptoms of irritable bowel syndrome (IBS)
How to Strengthen Your Child’s Immunity for Autumn? Types of Bifidus
Some of the most common and studied species include:
B. bifidum
B. longum
B. infantis
B. breve
B. lactis
Sources in food:
Fermented dairy products such as yoghurt and kefir
Certain types of cheese
Fermented vegetables such as sauerkraut
Probiotic supplements
Bifidus is often included in probiotic supplements, alone or in combination with other beneficial bacteria.
Factors affecting the Bifidus population:
Diet: fibre-rich food supports the growth of Bifidus
Age: Bifidus levels naturally decline with age
Stress: can reduce the number of beneficial bacteria
Antibiotics: can destroy both harmful and beneficial bacteria
We started giving Bifidus to our two boys at home from the third day of birth and have enjoyed calm babies who are now school children and enjoy good health, full of energy.

Essential fatty acids for strong immunity
Essential fatty acids are those that the body cannot produce on its own and must be obtained through food. They play a key role in many body functions, including maintaining a strong immune system.
Omega-3 fatty acids

- Types: EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid)
- Sources: oily fish (salmon, mackerel, sardines), flaxseed, chia, walnuts
- Immunity benefits:
- Reduce inflammation in the body
- Improve white blood cell function
- May reduce the risk of autoimmune diseases
- Improve the balance of intestinal microflora, which is closely linked to immunity
Omega-6 fatty acids
- Types: linoleic acid (LA) and gamma-linolenic acid (GLA)
- Sources: vegetable oils (sunflower, corn), nuts, seeds
- Immunity benefits:
- Involved in the production of prostaglandins, which regulate inflammation
- Support the normal functioning of immune cells
- They are important for maintaining the integrity of the skin, which is the immune system’s first line of defense
Omega-9 fatty acids:
- Not strictly “essential” but important for health
- Sources: olive oil, avocado, almonds
- Immunity benefits:
- Support the general health of the body, which indirectly affects immunity
- May help reduce inflammation
The balance between omega-3 and omega-6:
- It is important to maintain a proper balance between omega-3 and omega-6, aiming for a ratio of around 1:4
- Excessive intake of omega-6 at the expense of omega-3 can lead to higher levels of inflammation in the body
Applications for children
- Essential fatty acids are key for brain and nervous system development
- May help reduce allergic reactions in children
- Support skin health, which is especially important for children with eczema or other skin problems
Ways to include in the children’s diet:
- Adding ground flax seeds to cereal or yogurt.
- Offering nuts and seeds as a healthy snack (watch out for the age of the child and the risk of choking)
- Include oily fish in the menu at least once a week
- Using olive oil for salads and cooking
- Supplement as an Essential Fatty Acid Complex including Omegas 3,6 and 9 in the correct ratio.
Support the mucous membranes
- Essential fatty acids, especially omega-3, play an important role in maintaining mucosal health throughout the body
- Improve the structure and function of cell membranes in mucous membranes
- Strengthen the barrier function of mucous membranes, including those in the respiratory system
- This makes it harder for viruses and bacteria to penetrate the mucous membranes, especially in the respiratory tract
- Reduce inflammation in mucous membranes, which can help with allergies and respiratory problems
- Help produce protective mucus that traps and expels pathogens
This information highlights the importance of essential fatty acids not only for general immunity but also specifically for mucosal protection, which is particularly important for children’s respiratory health. Including foods rich in omega-3 and omega-6 fatty acids in children’s diets can help build stronger defences against respiratory infections, which is particularly important during the autumn and winter seasons.
Precautions:
- Always consult a paediatrician before making significant changes to a child’s diet
- Be careful with fish oil supplements and supplements containing Omegas harvested from large fish as they may contain heavy metals.
Including a variety of essential fatty acid sources in a child’s diet can be an effective way to support the immune system and overall health. It is important to take a balanced approach and consider the individual needs and possible allergies of the child.
