Your gut’s connection to your emotional state makes it your second brain
This post originally appeared November 12, 2018.
Have you ever heard of the gut-brain connection? If not, you’ve definitely experienced it. It’s that nervous feeling in your stomach when you’re in an unfamiliar situation or that full feeling when you’ve received unexpected sad news. Emotions such as happiness, anger, anxiety, and sadness can all cause a physical reaction in your gut.
The gut includes every organ involved in digesting food and processing it into waste. The gut or “second brain” can operate on its own and communicates back and forth with your actual brain. The vagus nerve controls messages to the gut and runs all the way from the brain stem to part of the colon. Hormones and neurotransmitters also connect your gut chemically to your brain.
Many contributing factors affect how your body digested and eliminates what you eat and drink. They include diet, food intolerances, lifestyle, hormones, sleep, and medications.
To maintain or restore gut health and support good overall health, it is important to maintain a strong balance of beneficial bacteria in your digestive tract. Eating a diet that includes foods with probiotic or prebiotic ingredients support a microbial health by restoring balance.
What are Probiotic Foods?
Probiotics contain live beneficial bacteria grown during carefully-controlled fermentation processes. You may already have probiotics in your diet: plain yogurt, kefir, cottage cheese, fresh sauerkraut, kimchi, kombucha, apple cider vinegar, and miso.
What are Prebiotic Foods?
Prebiotics do not contain bacteria. They contain indigestible fibers that ferment in the GI tract. There, they are consumed by probiotic bacteria and converted into other healthful substances. Prebiotic foods include artichokes, leeks, onions, garlic, chicory, cabbage, asparagus, legumes, and oats.
Are There Other Foods that Benefit the Gut-Brain relationship?
The following foods have also been shown to balance and improve the gut:
- Omega-3 fats
- High-fiber foods
- Polyphenol-rich foods
- Tryptophan-rich foods
If you’re experiencing indigestion or even if you are prone to depression or anxiety, you may want to look at your diet. By incorporating gut-healthy foods, you can begin to nurture your second brain.
