In the previous part of the cycle you learned how human immunity works. You also learned how to support it, which in practice can be difficult to implement. We want to help you with this, so especially for you we have found substances naturally occurring in nature that positively affect the work of the immune system and more!
We already know that good intestinal bacteria play an important role in maintaining health. Studies show that trillions of friendly microorganisms that are found in human intestines make someone slim, look young and enjoy a good physical and mental form. Scientists suggest that the intestines and good bacteria in it work together to defeat parasites, viruses and bacteria. However, to survive, friendly microorganisms need food, or prebiotics, the source of which is fiber.
Unfortunately, the typical western diet, which is growing in popularity in Poland, consists mainly of saturated fats and sugar. The World Health Organization (WHO) recommends eating between 25 and 29 grams of fiber each day as this reduces the risk of type II diabetes, heart disease, stroke and colon cancer. However, not every type of fiber has the same properties. One of those types of fiber that have been shown to be an effective prebiotic in research is nucleotides.
In the 2018 study, the nucleotides not only increased the variety and quantity of good bacteria, but also accelerated the adaptive immunity reaction that we wrote about in the previous article. A faster reaction of the immune system means that you will get sick for a shorter time ... if you notice that your body is fighting an infection at all. It may also be that the body will stop it so quickly that it will not develop. However, this is not the only property of nucleotides. Due to their prebiotic effect, nucleotides are effective in the treatment of irritable bowel syndrome (IBS) and accelerate wound healing.
Fukoidan is another type of prebiotic. Its exotic name sounds like a Japanese word and rightly so, because fukoidan is obtained from brown algae, which form the basis of Asian cuisine. The list of health benefits of fucoidan is impressive, but what you should primarily be interested in is its effect on immunity.
Do you remember how in the previous article we wrote about how vaccines work? In a nutshell: vaccines speed up the reaction of adaptive immunity. A 2013 study found that the aplication of fucoidan to those vaccinated against influenza increases the production of antibodies, which improves the preventive effect of the vaccine. However, this is not the end of fucoidan properties. Even if the infection is already infected, fucoidan directly destroys bacteria and viruses, reduces the inflammation associated with the infection, and even has an analgesic effect. So forget about "dying" because of the flu, even in the autumn and winter season. Fukoidan will, if you get sick at all, get the infection quickly and painlessly.
However, this is not the end of the long list of fucoidan benefits. In addition to having a positive effect on the immune system, fucoidan also works:
Of course, nucleotides and fucoidan are not the only substances found in nature that will improve the work of your immune system. Others include probiotics, vitamin D3, Omega-3, zinc, vitamin A and C.
