Probiotics are known as live microorganisms that can provide health benefits when consumed by improving or restoring the digestive system. They are considered safe, but can sometimes cause bacterial interactions and unwanted side effects. Probiotics can be found in many supplements and food, like yogurt, kefir, sauerkraut, tempeh, and kimchi.
Let us check out the benefits of probiotics:
- Importance of good bacteria
Probiotics might seem new to the food industry, but they have been an essential part for human consumption . When babies are born through natural process, they pick up a few good bacteria like Bacteroides, Bifidobacterium, Lactobacillus, and Escherichia coli from the mother. But when they are born through Cesarean section, these good bacteria are not transmitted to them. These babies are more prone to allergies that are caused because of a weak immune system.
- Good and bad gut bacteria
Probiotics can protect us in two ways. First, they improve our digestive system. We all know that our digestive tracts need a balance between the good and bad gut bacteria. Our poor food choices, stress, lack of sleep, antibiotics, and environment can influence or shift the balance of our body in favor of the bad bacteria. When our digestive tract is healthy, it can filter out things that can damage it, like harmful bacteria, toxins, chemicals, and other waste products. The healthy balance of bacteria can assist the regulation of gastrointestinal motility and maintain the function of the gut barrier.
- Healthy Immune System
Another way through which probiotics impact our immune system is by protecting it from germs. When our immune system does not function properly, we can easily suffer from many things like allergic reactions, autoimmune disorders such as Crohn’s disease, rheumatoid arthritis, and infections such as diarrhea, H. pylori, skin infections, and vaginal infections. By maintaining balance in the immune system, it can protect us from these harmful ailments.
According to probiotics manufacturers, there are many health benefits linked to consuming probiotics. However, there are also many related side effects which can affect a small percentage of the population. Let’s check out some of the side effects which can be cause by probiotics:
- Can cause unpleasant digestive symptoms:
One of the most commonly reported reactions with bacteria-based probiotic supplements is the increase in gas and bloating. People who consume yeast-based probiotics can experience constipation and increased thirst. To reduce this type of effect, you can start with a low dose of probiotics, slowly increase and help your body to adjust.
- Probiotic foods can trigger headaches
Probiotic-rich foods, like sauerkraut, yogurt, and kimchi, contain biogenic amines. Amines are substances that can form when protein-contained foods age or get fermented by bacteria. Some of the most common amines found in foods include histamine, tryptamine, tyramine, and phenylethylamine. They can excite the central nervous system, increasing and decreasing blood flow, which triggers headaches.
- Can increase infection risk
In some cases, the bacteria or yeasts, which are found in probiotics, can enter the bloodstream causing infections in individuals. They pose the greatest risk to people who have suppressed immune systems, prolonged hospitalizations, or those who have undergone recent surgeries.
- Strains can increase histamine levels
Sometimes, strain development used in these probiotic supplements can produce histamine in the digestive tract. Histamine is mainly produced by our immune system when it detects a threat. When the level rises the blood vessels dilate to bring more blood to the affected area. This process can create redness and swelling, which can trigger allergy symptoms such as watery eyes, itching, runny nose, or trouble breathing.
