The brain is the ‘central processing unit’ of the human system, the human system is as good as dead, if the brain doesn’t function. Without the brain giving signals to the rest of the organs to function right, it is impossible for these organs to survive on their own. So, it is safe to say that the brain is one of the most important organs of a human system.
Having a healthy brain means, your ability to concentrate, think rationally, memorize events, plan, learn, etc are normal. If these functions are not normal, due to some deficiencies or malfunctioning in the brain, then it could lead to severe health complications that hamper your daily life! The health of a human brain tends to deteriorate with age, especially if proper care is not taken. So, it is crucial that one leads a healthy lifestyle and take certain measures to ensure that their brain remains well-nourished, active and healthy! Now, we know that probiotics are healthy; did you also know that they are good for the brain? Find out why, here.
What Are Probiotics?
There are billions of bacteria living in the human body, which is a fact. Some of them are healthy; some of them can cause diseases. Now, the healthy bacteria aid various functions of the body, such as digestion, maintain the pH levels in certain organs, etc. Probiotics are microorganisms that are infused in certain foods, which when consumed increase the production of the healthy bacteria in our body, thus improving their functions.
Probiotics and the brain
Probiotics improve the production of healthy bacteria in the intestines. And the brain and the intestine are connected biochemically. So, if your intestines are healthy, your brain tends to remain healthy too, because, one of the types of healthy bacteria found in your gut can produce neurotransmitters and amino acids that can nourish brain cells.So, consuming probiotics on a regular basis is not only healthy for the gut, but also for the brain.
Taking probiotic supplements may reduce symptoms of stress, anxiety and depression
Stress and anxiety are increasingly common and depression is one of the leading causes of disease worldwide.A number of these disorders, especially stress and anxiety, are associated with high blood levels of cortisol, the human stress hormone.Only one study has examined how probiotics affect patients with clinically diagnosed depression.In the study, consuming a mixture of three Lactobacillus and Bifidobacteria strains for eight weeks significantly reduced depressive symptoms. The probiotic also reduced inflammation in the patients.A handful of other studies have examined how probiotics affect depressive symptoms in healthy subjects. In healthy people, certain probiotics may reduce:
- Symptoms of anxiety
- Depressive symptoms
- Psychological distress
- Academic stress
Certain probiotics may have benefits after traumatic brain injury
Traumatic brain injury usually involves admission to an intensive care unit. During this time, food is usually administered enterally, meaning through a tube.In some cases, breathing also has to be assisted with a tube, which can increase the risk of infection. Infections in people with traumatic brain injuries can lead to further complications. A few studies have found that adding certain probiotics into eternal nutrition can reduce the number of infections in the patients with traumatic brain injury and the length of time they spend in the intensive care unit.The effects of the probiotics on these outcomes may be due to their benefits for the immune system.
