Immune system and its meaning
The immune system is a collection of different organs, cells and substances that work in our body to protect us from illness. The human body provides a good environment for many viruses, bacteria, fungi and parasites, but the immune system restricts their access and development in the body, thus ensuring our health. The immune system is an entity that helps identify foreign microorganisms and its main function is to protect the body.
Can we strengthen our immune system?
This question is not quite right. In fact, we don't want it at all. When the immune system is overactive, autoimmune diseases may develop. It is our job to create the best possible conditions for the successful operation of our immune system; Our goal is not to interfere with the immune system. Supporting the immune system is a comprehensive approach that we look at in this article.
The immune system covers our entire body. Its most important parts include immune cells, some of which are constantly circulating in our vascular system, observing and identifying possible foreign substances - antigens. 70-80 % of the body's immune cells are located in the digestive tract. The intestinal microphlorora is often called "additional organs" because it performs many vital functions.
The microbiom and immune system of the digestive system form a close and friendly relationship, and only as a result of a successful cooperation, the immune system can function normally. The development of the immune system and the efficiency of the immune response go hand in hand with the development and composition of the intestinal microbiom. Intestinal microbes and mammals have evolved together, so as microbes receive a safe habitat, they provide regulation for many physiological functions, including protection against pathogens.
Changes in microbioma in an unbalanced diet, sitting -oriented lifestyle, stress, antibiotic use and other causes lead to changes in the interaction between the microbiome and the host, in this case man. As a result, health problems may occur, such as increased susceptibility to infections.
How to maintain health during the cold season?
When thinking about how to stay healthy during the cold season, the most important thing is to take care of the well -being of the digestive tract. If the digestive tract is healthy, it will be better able to fight disease -causing pathogens. That's why I start by making recommendations related to nutrition.
The food we eat affects the diversity and composition of the bacteria in the intestine, which in turn affects immune cells.
Eat a balanced diet.
In order for our immune system to work successfully, it is important to get enough protein daily. The optimum amount is 1 g of protein per kilogram of body weight. For example, if you weigh 60 kg, you need 60 grams of protein a day.
Protein sources in the diet are:
- Meat
- Fish and other seafood
- Dairy products
- Balls
- Legumes
- Soy products
Protein content in different products:
- Fat -free cottage cheese: 100 grams of 18 grams of protein.
- Kefir: 100 grams of 3 grams of protein.
- 1 egg: 7 grams of protein.
- 100 grams of salmon: 21 grams of protein.
- 100 grams of chicken breast: 22 grams of protein.
- 100 grams of cooked lenses: 8-10 grams of protein.
- Edamame beans: 100 grams of 11 grams of protein.
- Bean flour: 100 grams of about 26 grams of protein.
- Mozzarella: about 20 grams of protein.
To support immunity, it is also important to get enough fiber and antioxidants from whole grains, legumes, fruits, berries, vegetables, nuts and seeds. It is important to add that (especially during the cold season) the frozen vegetables, fruits and berries are also suitable for this purpose. It is a myth that freezed foods do not have the necessary nutrients. Although they contain fewer vitamins than, for example, freshly picked vegetables or berries, their nutrients are often better than long -distance products that have been on store shelves.
When switching to vegetables, fruits and berries, it is important to remember to consume at least 500 grams a day.
How much is this?
One tomato weighs about 150 grams, one banana about 100 grams, one paprika 150-175 grams, one pear about 150 grams. Although I do not recommend weighing vegetables and fruits, eating vegetables, fruit or berries at every meal, 500 grams is easily full. It is important to emphasize vegetables. For example, two of the three meals should contain vegetables and one fruit/berries. The daily amount of fruit/berries is about 200 grams, which corresponds to two fruits or 200 grams of berries.
Whole grain products (like buckwheat, whole grain rice, cereals, oatmeal and whole grain bread) are also an important part of the diet. In general, complex carbohydrates support microbiom. Whole grains contain protein, many vitamins and minerals, and such as vegetables, fruits, legumes, nuts and seeds, including fiber.
Fibers and their role in the immune system:
The fiber is a carbohydrate that is not broken down or absorbed in the digestive tract such as other nutrients. However, the fiber has many good qualities related to the immune system.
There are two types of fiber:
- Insoluble fiber You can find whole grains, fruits, vegetables (peel), nuts and seeds. It improves stomach function and reduces the risk of constipation.
- Soluble fiber There are legumes, fruits, nuts, seeds, vegetables and oats. It lowers the level of "poor cholesterol" in the blood and acts as a nutrition for a good bacterial strain in the intestine, which is essential for immunity.
The recommended daily fiber intake is about 30-35 grams.
The amount of fiber in different products:
- Pear or apple: about 6 grams.
- Avocado: about 10 grams.
- Carrot/beetroot: about 4 grams.
- Lenses: 5 grams/100 grams.
- Legumes: 7-9 grams/100 grams.
- Oatmeal: 10 grams/100 grams.
- Raspberries: about 6 grams/100 grams.
- Broccoli: about 3 grams/100 grams.
If you do not get enough fiber daily, do not try to eat 30 grams at a time the next day. It is important to increase the amount of fiber in the diet gradually. A sudden change can cause flatulence or other digestive problems.
