Healthy Gut, Happy Brain

When we understand how to care for our gut, we can feel the benefits!

From a functional nutrition perspective, everything starts in the gut and what it can do with the foods we eat. There are billions of microorganisms living in our gut that have a beneficial relationship with us. We feed them and they “feed” us. But this relationship can become non-beneficial, if the microorganisms and their environment gets unbalanced, compromising digestion amongst other things, while a healthy gut will get the best out of the foods we eat.
Highly processed foods like refined sugars, oils and meat, most packaged foods, artificial sweeteners, and alcohol can unbalance the gut environment, making it favorable for some of the microorganisms living in our digestive tract to overgrow or die, leading to a dysfunctional (inefficient) gut, when it comes to digesting and absorbing what we eat. By gut I mean digestion from top to bottom, but more specifically our intestines, where our immune system is very active. Vegetables, whole grains and fermented foods on the other hand, can help to keep the environment in check. Fermented foods like sauerkraut and yogurt contain living bacterias and are called probiotics foods, which means “foods in favor of living organisms”.

The Microbiome

This whole environment and its organisms is called microbiome and it plays a huge role in our mood and immunity. Our gut and brain are connected by an important nerve called vagus nerve and by receptors through our digestive tract, They are both signaling to each other how we are feeling, what we are lacking. For example, some food cravings and mood swings can be related to the population of certain microbes and their communication with the brain, or perhaps to the lack of a nutrient that microbes are sensing. Our immunity is in play also when there’s an unhealthy microbiome, since our gut is part of our immunological barrier, making us more or less resilient to viruses and bacterias we ingest everyday. And because the breakdown of the foods we eat is done with the help of microbes, the condition of the gut compromises or enables nutrient absorption and, consequently, all the goodies to get into our blood stream to feed our cells.
It’s important to remember that everyone’s gut is different, depending on what we’ve been exposed to throughout life, that’s why what works for you may not work for me. But as a rule of thumb, our microbiome thrives on diversity, prebiotics (fiber, fruits, vegetables, wholes foods) and probiotics (fermented foods like sauerkraut and yogurt) foods, and the relationships between them are a way to regulate their environment. It’s a complex subject that has a lot to be discovered, but its importance is well known.

Exercise and the Microbiome

Exercise itself is positive for the health of the digestive system, but when training hard, it’s even more important to care for our nutrition, going for what’s soothing and nutritious and avoiding what doesn’t work for you. In endurance sports, therefore, fueling properly is even more important to support the digestion itself and the load on the digestive system, which is breaking down and absorbing nutrients as we train and our body adapts and metabolizes. And here is great news: research has found that a healthy microbiome can help metabolize lactate more efficiently, turning it into a beneficial byproduct for our body to reutilize, which is very positive for athletes.

A balanced and healthy microbiome can be the decisive factor in your athletic development. Directly, it helps your workout performance by optimising substrate utilisation and boosting your energy level. Indirectly, because of its critical role in immune function; preventing you from getting sick and missing training.

Something for you to try...

It’s never too late to start caring for your gut, you can start by including probiotics foods to your diet. Even a small portion everyday can go a long way, specially if it’s consistent. Also, you can watch for highly processed foods you consume, like refined sugar, that sneaks in breads, sauces, canned foods. Practice reading the nutrition facts labels and ingredients on the back of packages, to know where the sugar you eat is coming from. In addition to that, try to go for products that choose clean sources of sugar as ingredients, like honey and coconut sugar. And keep it up!
