The human microbiome is a hot topic of research right now, as scientists are learning more about the trillions of bacteria that live on and in our bodies. Recent studies have shown that the microbiome plays a role in everything from digestion to autoimmune diseases to mental health. So how does the microbiome affect our health? Here are just a few ways:
- The microbiome can play a role in obesity and weight loss. For example, scientists have found that obese people tend to have different gut bacteria than thin people. Gut bacteria can influence weight by affecting how we digest food and absorb nutrients.
- The microbiome can also affect our immune system. The bacteria in our gut help to train our immune system cells, and can influence whether we develop allergies or autoimmune diseases.
- The microbiome can also affect our mood and emotions. Some scientists believe that the gut-brain connection may be responsible for conditions like anxiety and depression.
