Human gut microbiome is a compilation of many different bacteria, which has ignited the curiosity in researchers. Studies were conducted to see how they reacted to different food types. 34 participants were examined for 17 days to check how their gut bacteria reacted to different foods on an everyday basis. The results showed that even the foods which contained similar nutritional profile instilled different reactions in microbiomes. This result is a proof that gut microbiomes can be studied only through a much expansive research. "We had to scratch our heads and come up with a new approach for measuring and comparing the different foods,", says senior author Dan Knights. Researchers say that doing more researches on gut microbiome can help focus on an overall positive shift of a person’s health. “This study suggests that it's more complicated than just looking at dietary components like fiber and sugar. Much more research is needed before we can understand how the full range of nutrients in food affects how the microbiome responds to what we eat." says Dan Knights.
