Digestive health and immunity -

diet, environment, lifestyle habits. For instance, the gut microbiome acts as a gatekeeper and a trainer. It teaches immune cells called T-cells to distinguish foreign entities from our own tissue. When antibodies cannot access certain pathogens that have managed to attack our cells, T-cells mediate the situation and destroy infected cells — this process is referred to as cell-mediated immunity.

We see the importance of maintaining a powerful immune system and proper communication with the gut. When everything is running smoothly, the gut sends signals for the development of healthy immune function modulating immune responses. In exchange, the immune system helps to populate the microbiome with health-promoting microbes.

When these two are in good relations, the body is equipped to respond to pathogens and to tolerate harmless bacteria, preventing an autoimmune response and ensuring overall well-being.

Moreover, it has been well established that the abnormalities in the communication between intestinal bacteria and the immune cells can contribute to disease. Because the immune system is intricately related to the gut microbiota, if the body is exposed to bacteria-stripping factors i.

poor diet, antibiotics, surgeries, heavy metals, chemotherapy. The intestinal lining of your gut is delicate, and when it is weakened, you are more vulnerable in the face of new harmful invaders. When your gut is out of balance, meaning not enough good friendly bacteria vs.

the pathogenic, your whole body is affected. Epigenetic research is finding that we have more control over our biodiversity than we think. Genes can be influenced. Changing the way you eat can change the expression of your genes by populating the microbiome with diverse microbial cells.

Improving your diet by cutting out processed foods and including more prebiotic fibre vegetables and legumes can increase biodiversity. Also, having probiotic-rich foods such as kefir, sauerkraut, and probiotics may restore the composition and reintroduce strong microbes, allowing for a more efficient gut microbiome, immunity and cognitive abilities.

Every time we eat, our gut bacteria break down our food and use it to grow. As this process occurs, healthy gut bacteria produce beneficial compounds that help you function optimally and are beneficial for the way your immune system functions.

This can be caused by stress, a highly processed diet or repeated bouts of antibiotics, amongst other things. Having a gut containing plenty of healthy bacteria leaves the immune system with plenty of time to handle its many complex everyday functions.

But what we do know, is that eating a diet rich in vegetables and fruit and healthy fibres see below , as well as low in sugar and processed foods, can help the balance of bacteria in our gut. Try also, to ensure you eat mindfully and slowly, sitting down at the table and taking the time to be present with your food.

This helps the digestive process; essential to gut health. Your snot colour can tell you a lot about your overall health.

Not immunith ago, we held the belief that bacteria Digestive health and immunity little Bone strength do with our well-being and andd it heqlth separate entity that just assisted the digestion of Energy Bars for Recovery foods. More recently, Fat metabolism and muscle loss has become a fact that humans possess as many bacterial cells as human cells — with over 10 species and trillions of microorganisms present in our gut! Thanks to medical advances and the lowered costs of genetic sequencing, knowledge about bacteria are continually growing. In fact, scientists believe the bacteria contribute greatly to our level of well-being and health, specifically the bacteria found in our gut. The gut microbiome — which is a collection of bacteria that reside in the gut — is being thoroughly studied in many specialities as it has such widespread effects on the body, ranging from cognitive function, behaviour, appetite, metabolism, immunity, and digestive health the list goes on. Recovering from Exercise with Nutrition, an international anx of Digesgive has found the molecular Fat metabolism and muscle loss of this concept, Dogestive how diet ultimately ehalth immunity through the immunty microbiome. Qnd more HMS news here. The findings, healhh Nov. The experiments pinpoint a Dkgestive molecule, the synthesis Bone strength release of which Digestive health and immunity influenced by Fat metabolism and muscle loss diet. That molecule, in turn, stimulates the activation and signaling of a subset of cells known as natural killer NK T cells, which are involved in immune regulation and implicated in a range of inflammatory conditions. While scientists have surmised for a long time that diet plays a role in immune health, the new study elucidates the precise molecular cascade behind this interplay, said study senior author Dennis Kasperprofessor of immunology in the Blavatnik Institute at Harvard Medical School. If confirmed in larger animals and eventually in humans, the findings can help inform the design of small-molecule treatments that enhance both intestinal and overall immunity, the researchers said.
