Beneficial, harmful, and opportunistic bacteria Typical intestinal bacteria are classified according to their actions into three types.

Similar mouse studies show gut bacteria affect anxiety. Kirsten Tillisch, professor of medicine at the David Geffen School of Medicine at the University of California, Los Angeles, led a study in that was the first to show eating a bacteria-friendly, or probiotic, food — in this case, yogurt — affected regions in the brain associated with processing of emotion and sensation in healthy women with no psychiatric symptoms.
Four years later, her team linked specific gut bacterial profiles to brain differences in those regions. First, the number of bacteria in your gut is vast — 50 trillion or so, which equals about one for every human cell in our bodies.
The makeup of this bacterial collection, or microbiome, is affected by many things, including diet, exercise and cultural influences. Those bacteria interact with the brain and other organs in three ways. First, the gut and brain communicate by molecules carried in the blood, and microbes influence those chemical messages.
Microbes also interact with the gut's special nervous system, called the enteric nervous system. It has a direct, two-way connection with the brain via the central nervous system.
Finally, the immune system of the gut wall and the body's other immune components respond to gut microbes, affecting the brain and organs. Here's one example of how it all ties together.
You might have heard of serotonin and dopamine, neurotransmitter molecules that steer mood and behavior in brain circuits. Some ways to lower stress may include meditation, walking, getting a massage, spending time with friends or family, diffusing essential oils, decreasing caffeine intake, laughing, yoga, or having a pet. Here are 10 ways to reduce feeling stressed.
Not getting enough or sufficient quality of sleep can have serious impacts on your gut health, which can in turn contribute to more sleep issues. Try to prioritize getting at least 7—8 hours of uninterrupted sleep per night. Your doctor may be able to help if you have trouble sleeping. Chewing your food thoroughly and eating your meals more slowly can help promote full digestion and absorption of nutrients. This may help you reduce digestive discomfort and maintain a healthy gut.
Drinking plenty of water has been shown to have a beneficial effect on the mucosal lining of the intestines, as well as on the balance of good bacteria in the gut. Staying hydrated is a simple way to promote a healthy gut. Adding a prebiotic or probiotic supplement to your diet may be a great way to improve your gut health. People with bacterial overgrowth, such as SIBO, should not take probiotics.
Not all probiotic supplements are high quality or will actually provide benefit. Show now for a probiotic or prebiotic supplement. If you have symptoms such as cramping, bloating, abdominal pain, diarrhea, rashes, nausea, fatigue, and acid reflux, you may be suffering from a food intolerance. You can try eliminating common trigger foods to see if your symptoms improve. If you are able to identify a food or foods that are contributing to your symptoms, you may see a positive change in your digestive health by changing your eating habits.
Reducing the amount of processed, high-sugar, and high-fat foods that you eat can contribute to better gut health. Additionally, eating plenty of plant-based foods and lean protein can positively impact your gut. A diet high in fiber has been shown to contribute tremendously to a healthy gut microbiome.
