Gut health and its impact on immunity and ageing

Gut health and its impact on immunity and ageing

The majority of us are aware of the concept of "gut health" and understand its importance to our overall well-being. But what exactly does having a healthy gut mean?

Our gut is home to millions of microorganisms, with about 1000 distinct species, including various types of viruses, bacteria, yeast, and other fungal bodies. Some of these microorganisms are harmful to our health and others are very beneficial and important for a healthy body. Studies on people who have lived to be 100 years old in Blue Zones around the world have also shown that the structure and function of the gut microbiome determine whether or not a person will live to be 100 years old in good health. These people also appear to have high populations of "good bacteria." A healthy gut is said to be when there is a good balance between the good as well as the bad bacteria and viruses. In other words, if your gut health is poor, your immune system, hormones, and general health will suffer as a result. Some of the research has also indicated that having a variety of bacteria in your gut may lower the risk of diseases including psoriatic arthritis, inflammatory bowel disease, and diabetes.

According to studies, the secret to healthy aging may lie in maintaining a healthy gut. Everything starts with our gut. It facilitates the breakdown of the food we eat, takes in nutrients, and utilizes them to energize and sustain our bodies. It is, therefore, more difficult to maintain good health and healthy ageing if our gut is out of balance and our immune system isn't functioning properly. Our body eliminates metabolic waste and pollutants in our gut. However, our body will find it difficult to eliminate those toxins if we have a poor digestive system. People, therefore, encounter symptoms including brain fog, constipation, joint discomfort, etc.

Gut health plays a crucial role in both immunity and aging. Here's how it can impact these aspects:

Immune System Function:

The gut is closely connected to the immune system. Study shows about 70-80% of the body's immune cells are located in the gut. A healthy gut microbiome helps regulate and support the immune system, promoting a balanced immune response. The beneficial bacteria in the gut interact with the immune cells, influencing their development and activity. They also help prevent the overgrowth of harmful bacteria that can cause infections and inflammation. When the gut microbiome is imbalanced, it can lead to immune dysregulation, making the body more susceptible to infections, allergies, and autoimmune disorders.

Inflammation Control: 

Chronic inflammation is a key factor in various age-related diseases, such as cardiovascular disease, diabetes, and neurodegenerative disorders. A healthy gut microbiome helps maintain a balanced inflammatory response in the body. It produces short-chain fatty acids (SCFAs) from dietary fiber, which have anti-inflammatory properties. Additionally, certain beneficial bacteria can stimulate the production of regulatory T-cells, which help control inflammation. By promoting a healthy gut, you can potentially reduce chronic inflammation and lower the risk of age-related diseases.

Nutrient Absorption:

As we age, the ability to absorb nutrients from food may decline. A healthy gut with a diverse and robust microbiome helps enhance nutrient absorption. The beneficial bacteria in the gut can break down complex carbohydrates, fibers, and other nutrients that our bodies cannot digest on their own. They produce enzymes that aid in the digestion and absorption of these nutrients, making them more bioavailable to the body. Proper nutrient absorption is vital for maintaining optimal immune function and supporting overall health as we age.

Protection against Pathogens:

The gut microbiome acts as a barrier against pathogens and harmful bacteria. Beneficial bacteria compete with pathogenic microbes for space and nutrients in the gut, preventing their colonization. They also produce antimicrobial substances and strengthen the gut lining, making it more resistant to pathogens. When the gut microbiome is imbalanced, it can compromise this protective function, leading to increased susceptibility to infections and weakened immune defenses.

Brain-Gut Axis:

The gut and the brain are interconnected through a bidirectional communication pathway called the gut-brain axis. The gut microbiome influences the production of neurotransmitters and chemicals that affect mood, cognition, and behavior. Imbalances in the gut microbiome have been linked to mood disorders, such as anxiety and depression, which can impact overall well-being and quality of life as we age. By maintaining a healthy gut, we can support a balanced gut-brain axis, promoting mental and emotional health.
Below mentioned are some tips to improve your Gut health and boost immunity and ageing:


  • Consuming a variety of fruits, vegetables, and legumes
  • Fruits and vegetables are the best sources of nourishment for a healthy microbiome since they are high in fiber. Fiber may be broken down by certain bacteria in our stomach, which encourages the growth of those bacteria. Legumes and beans both contain a lot of fiber. Bifidobacteria, for instance, are beneficial bacteria because they may lessen intestinal inflammation and enhance gut health. It has been proven that eating foods including apples, artichokes, blueberries, almonds, and pistachios increases a person's Bifidobacteria levels. 


  • Exercising Regularly
  • The majority of the bacteria in our guts have a symbiotic connection with our bodies, which means that both of our systems contribute to the health and growth of these microorganisms as well as their support of bodily functions. They generate vitamins, fatty acids, and amino acids that are necessary for a variety of processes, including immune system health, digestion, mood management, and more. Exercise on a regular basis quickens the process, increasing the variety of microbial species in the stomach and promoting the growth of bacteria.


  • Reduce Your Alcohol Consumption
  • Your microbiome may also be badly impacted by excessive drinking. Recurrent alcohol consumption is connected to gastritis, an inflammation of the gut that causes discomfort. Heartburn, ongoing pain, ulcers, and bacterial infections can all result from such inflammation. Additionally, excessive drinking is linked to intestinal inflammation, which is an indication of a bad gut. According to research, this form of inflammation can upset the microbiota's balance and change how well it functions. 


  • Health Supplements
  • Health Supplements may improve or prevent gut inflammation as well as other intestinal or systemic disease phenotypes by re-establishing the balance of the gut microbiome and introducing beneficial functionalities to the gut microbiome. Probiotics may be very useful for elderly people, notably in terms of infection prevention and potentially also in the prevention of a number of age-related disorders.


  • Consuming Natural Supplements
  • It is important to make sure that our body has adequate levels of vitamins, minerals, enzymes, and even microorganisms to make sure we perform and function at our peak. Different supplements like Glutathione, Magnesium complex, NAD+ booster, Alpha KetoGlutarate, Probiotics, Colostrum, and Omegas constantly help our body manage this network of metabolism and make sure that no processes in our body are short-circuited because of lack of an important molecule.

    In conclusion, your intestines are home to billions of bacteria that are vital to your health. On the other hand, modern diets heavy in fatty, salty, or sugary processed foods may impair the ageing gut, whereas higher fiber foods like fruits, vegetables, seeds, beans, and nuts, together with regular exercise, may assist maintain a healthy gut microbial balance as we age. As a result, it may serve as a warning sign for a variety of chronic illnesses. Maintaining the gut health is crucial for many elements of normal physiology, especially as we become older as longevity and the ageing process are significantly influenced by the gut microbiome. The good news is that the gut microbiome can be used to combat age-related cognitive decline with the use of modern supplements.
