The gut microbiota is a collection of microorganisms living in the digestive tract. Over 100 trillion microbial organisms in the gut help with food digestion, immune system regulation, protection against pathogenic bacteria, and vitamin synthesis. Research indicates that lower gut bacterial diversity is associated with reduced immune activity and the emergence of metabolic syndrome.
Many studies have unanimously revealed a direct connection between gut microbiota health and the socioeconomic status of individuals. Remarkably, individuals with lower socioeconomic status have reduced gut microbiota diversity. Those people usually have poor nutritional intake, limited access to fresh and nutritious food, obesity, and medication which can result in decreased diversity. Furthermore, factors such as age, gender, and race are identified as influential determinants of gut microbiota composition.
Dietary choices with abundant fruit and vegetables will increase the diversity of gut microbiota. Consumption of a diverse range of food rich in prebiotics including bananas, yogurt, garlic, asparagus, flaxseeds, and onions will help. These dietary practices can positively improve gut microbiota and overall health outcomes.
