Your mental and physical health are affected by so many things. The food you eat, the exercise you get (or don’t get), and the health of your gut. “Your gut,” you ask? Yes indeed. This is the center of many functions and systems in the body that play a vital role in regulating your mental and physical health. The central nervous system (CNS) and immune system are primarily affected by your gut health. Good gut health = optimal functioning CNS and immunity. Bad gut health = suboptimal CNS and immunity functions. These functions are directly correlated to your wellness. Read on to learn more how gut health is the secret to mental & physical health.


What functions does the gut serve?

After the food in your esophagus passes into your stomach, it is broken down by acid and enzymes. The small intestine absorbs carbohydrates, fats, and proteins. It also absorbs the nutrients and water via digestive juices and enzymes. The gut microbiome produces enzymes that break down and process food, regulate the immune system, produce vitamins and protect against pathogenic bacteria. The bacteria in our gut microbiome are responsible for this function. Your gut microbiome is formed by a variety of factors from diet to climate.

The large intestine is the last part of the digestive system. This is where remaining nutrients and water are broken down and absorbed, vitamin K is generated, and waste products are converted into stool before being eliminated. The signals between the brain and the gut are complicated and involve hormones and nerves in the process of digestion. Because of the gut-brain connection, our body’s immune system, metabolism, and mental well-being may all be impacted. This part of our body is therefore important to our immune system, metabolism, and mental health, known as the gut-brain connection. The gut microbiome and human biology are both important in understanding our health if these two key parts are combined.

The Gut-Brain Connection.

The immune system’s largest quantity of cells is found in the gut. These cells are always in contact with the gut microbiome to keep it in balance. Things like diet, stress, medications, and antibiotics affect the gut microbiome. This in turn impacts our overall well-being because it disrupts the gut-brain connection. To maintain a healthy gut microbiome, it’s important to maintain a proper balance of bacteria in the intestinal barrier. In leaky gut syndrome, this intestinal barrier is weakened, allowing microorganisms to escape into the body. Leaky gut syndrome has been linked to inflammatory bowel disease, depression, anxiety, and autism, among other things. This is why gut health is the secret to mental and physical health.

An imbalance of gut bacteria can also cause problems with the blood-brain barrier and increase symptoms of depression and anxiety. Increases in cytokine production (cell signaling proteins) and permeability of the blood-brain barrier due to gut inflammation result in even more molecules escaping the gut, leading to increased symptoms of depression and anxiety.

These are some signs and symptoms of an unhealthy or unhappy gut:

  • Upset stomach and nausea

  • High sugar diet

  • Skin irritation

  • Food intolerances

What You Can Do To Maintain A Healthy Gut.

Gut health can be improved by diet and water intake. Dietary fiber plays a critical part in the creation of short-chain fatty acids, which are crucial for cell signaling (how the cells, brain, and immune system work together). Foods such as whole grain pasta and rice, broccoli, beans, nuts, and legumes all provide dietary fiber. It is also critical to consume enough water. Water helps maintain the intestinal mucosal layer to prevent intestinal leakiness by maintaining it hydrated.

Another beneficial food is probiotics in fermented foods. Fermented foods include yogurt, tempeh, miso, and kefir. These foods preserve gut health. Probiotics are live organisms that help maintain gut flora, or the organism and good bacteria that break down food.

Food intolerances can also cause an unhealthy gut, so it is worth doing an elimination diet to see if it improves your symptoms. If you suspect you have a food allergy, you must seek medical advice and have it tested. Food allergies are distinct from intolerances in that they trigger an immune response and require medical treatment.
