Less diversity and imbalance of gut microbes influences diseases such irritable bowel syndrome, inflammatory bowel disease, colorectal cancer, obesity and Type 2 diabetes. There are some strategies to manipulate the gut microflora
- Eating fermented product – Fermented products as pickles or yogurt not only provide us some beneficial enzyme for the digestive system but also induce various, new strains of microbes to gut environment and enhance its function.These will improve the diversity of our gut microbial ecosystem which will bring us many benefits to avoid diseases relating to gut microbes.
- Eating diverse range of foods – A diet with different food types will diverse gut microbes. The more diverse, the healthier digestive system. Diets with lots of vegetables, legumes, beans and fruits are much better than high sugar, red meat. Fiber promotes the growth of gut microbes, provide vitamins and antioxidants necessary for body’s mechanism, and enhances our immune system.
- Adap a healthy lifestyle – Stress and unhealthy lifestyle makes us to be more susceptible to inflammation. A study of age-related physiological changes in the gastrointestinal tract of older people that are characterized by a chronic low-grade inflammation which can lead to a microbial imbalance. Aged and inflammation can create imbalance in gut microflora so a healthy life such as exercise, eating rich fiber diets, coping with stress would endurance immune system to fight back infectious agents as bacteria, virus.
- Eliminate processed food and reduce amount of sugar consumption – Sugar is the good source for microbes, consumption of large amount of sugar and trans-fats impacts on the proportion of gut microbial species in gastrointestinal tract. Processed food and sugar is one of causes for obesity. Gut microbes and obesity are close related together. Reducing obesity can improve the gut microbiota because studies show that there is reduces some species as Bacteroidetes, Firmicutes phyla, Clostridium leptum in obesity patients.
- Take prebiotics and probiotics supplements – Taking some extra probiotics can induce new strains to gut microflora helping balance between gut species which give us benefits for reducing risks of inflammation of GI tract.
- Limit antibiotics – Antibiotics kills target bacteria, but also affects flora bacteria including gut microbiota. These effects can be neutral or harmful to individual in short period of time, the gut microbes can be recover after stop taking antibiotics. But I it will affect the entire gut microbe system in the community for long time run.
