The bacteria that live in the Gut offer numerous health benefits such as synthesis of Vitamin K, boosting immunity and metabolism of bile acids. Gut flora are partially inherited from the mother at birth and the other half is determined by lifestyle factors such as dietary intake, stress, and age. A newborn baby is sterile and bacteria colonize the exposed lining of the digestive tract by entering through the oral pathway. The diet and nutrients received help in creating the microbial environment in the digestive tract. The composition of gut flora keeps varying from time to time and is unique for each individual based on lifestyle factors, exercise, stress, illness and age. Gut bugs are flexible and change according to the needs of the diet. For instance, Japanese individuals are able to partially digest seaweed due to the personalization of their digestive tract by certain bacteria. The gut bugs that are comprised of trillions of cells and have nearly 1000 diverse species within our digestive system are responsible for more than just basic digestive functions. Studies have shown several connections between the presence of gut flora and overall health. They can be the biggest ally in order to stay healthy or be the worst enemies based on the composition of the bacteria.
