With 100 trillion bacteria living in our guts, we have more bacteria cells in our bodies than human cells, so it’s no wonder that this vibrant community of microflora have a huge impact on our lives. Relation between the gut microbiota and human health is being increasingly recognised. It is now well established that a healthy gut flora is largely responsible for overall health of the host. Your gut health has also a great impact in your mood
, as it stores 95% of your serotonin
. We should consider our gut bacteria some of our best friends and care for them appropriately.
Humans have been consuming sources of probiotics for thousands of years in fermented foods and foods high in probiotic activity such as miso, kimchi and kombucha. But what exactly are probiotics? What is the difference between probiotics and prebiotics? And how can we promote their growth and development in our guts?
What are probiotics?
The term probiotic refers to the microorganisms in our guts, which promote health, primarily made up of bacteria. The most common bacteria found in human guts are Lactobacillus
, although there are at least 1000 different species living in our guts with more than 3 million genes
. The gut flora found naturally in your gut is known as your “indigenous” probiotics, but you can also introduce probiotics in your system externally in the form of probiotic foods and supplements.
We live in symbiosis with our probiotics, while they get to make their home in our intestinal tract we receive numerous benefits in return, including:
- Nutritional benefits, helping us to break down food for improved absorption
- Supporting our digestive tract
- Helping relieve digestive discomfort such as symptoms of bloating, gas or flatulence
- Outcompeting bad bacteria in our guts.
- Supporting our immune system and mood. While studies on both these benefits are still in their infancy, new research is showing a strong connection between gut health and immune and serotonin.
The ratio of probiotics in your gut is incredibly important; an imbalance between the good and bad bacteria is known as dysbiosis, symptoms of which can include cramping, bloating, diarrhea or constipation. An imbalance in your gut can be caused by a myriad of things including stress, food, antibiotics and aging, some of which are unavoidable in our busy lives. Not only is your digestive health at risk if you don’t have the correct balance of probiotics in your gut, but this can be followed by a decline in both your mental health and immune health, meaning you are more likely to get colds, flus and other infections. For these reasons, it can be incredibly beneficial to take a probiotic regularly and eat probiotic foods such as yoghurt, cheese, sauerkraut, miso, tempeh and sourdough bread.
Prebiotics vs Probiotics
But what is the difference between prebiotics and probiotics?
The Mayo Clinic for health defines prebiotics as nondigestible substances that act as food for the gut microbiota. Essentially, prebiotics stimulate growth or activity of certain healthy bacteria that live in your body.
So, while the good bacteria themselves are probiotics, prebiotics are the food we feed our gut flora.
When taken together, prebiotics and probiotics form a symbiotic relationship, allowing them to function at an optimum level.
According to the Monash University, you can find prebiotic in the following food:
What is the Right Probiotic for me?
- Jerusalem artichokes, chicory, garlic, onion, leek, shallots, spring onion, asparagus, beetroot, fennel bulb, green peas, snow peas, sweetcorn, savoy cabbage
- Chickpeas, lentils, red kidney beans, baked beans, soybeans
- Custard apples, nectarines, white peaches, persimmon, tamarillo, watermelon, rambutan, grapefruit, pomegranate. Dried fruit (eg. dates, figs)
If you have fair digestion but are looking for a daily support for your gut health and your immunity, you can take a Daily probiotic such as Nutra-Life ProBiotica™ Daily Health
. If you are suffering from regular stress, digestive discomfort, have taken an antibiotic course, or are travelling, your gut microbiota might be out of balance. You might need a high strength, multi strains probiotic like Nutra-Life ProBiotica™ High Potency.
