Good Health Starts in the Gut
Did you know that the bacteria in your gut – your microbiome – can weigh as much as your brain? Your microbiome could even be considered an organ in its own right, and plays an important role in your health and happiness.
From immune function to brain activity, nutrient synthesis to elimination of toxins, the bacterial balance in your gut affects almost all aspects of your health. That’s why it’s essential to maintain a diverse microbiome for good all-round health, and to support healthy bacterial balance.*
Unfavorable Gut Bacteria
There are more bacteria in the intestines than there are cells in the body. In fact, on the basis of cell numbers alone, we are 10% human and 90% bacteria!
Every person’s gut flora is unique, but most of us have at least 700 species of bacteria living in our intestines at any one time. Around 85% of normal gut flora is made up of beneficial bacteria, i.e., species we want to have around because they perform useful actions like synthesizing vitamins or breaking down our food to release energy. The other 15%, however, is made up of potentially unfavorable pathogenic bacteria, i.e., those that can undermine health if they get out of hand.
When this 85:15 ratio is maintained, we call that a state of eubiosis. When the unfavorable bacteria increase in number, this can cause dysbiosis, which can have unpleasant effects on health. The shifting balance of gut bacteria can have a major impact on immune system health, for example, as well as affecting hormone balance, inflammation, and even cognitive function.
Signs of an Unhappy Gut
When your microbiome is upset by stress, antibiotic use, illness, infection, or a diet high in refined sugar, tummy troubles can quickly put a cramp in your style. An imbalance in gut bacteria has been associated with a wide variety of digestive issues and other problems, including:
- Brain fog
- Frequent antibiotic use
If you’re struggling with any of the symptoms above, you’ll want to know how to support healthy bacterial balance. One way to replenish and restore a healthy microbiome is to increase your intake of prebiotic and probiotic foods.*
Gut-Friendly Foods (Prebiotic and Probiotic Foods)
Prebiotic foods, including fresh fruit, vegetables, and legumes, are a great way to support your intestinal microflora. These foods contain a type of fiber that we cannot digest, but that good bacteria love! Check out our blog How to Maintain a Probiotic-Freindly Diet for more tips.*
Many fermented foods, such as kimchi, sauerkraut, and kefir are a source of probiotics and prebiotics, as is cultured yogurt. Many store-bought versions of fermented foods are pasteurized, however, and do not contain any live bacteria, so be sure to check the label or make your own fermented foods at home.*
How Probiotics Support Good Health
Probiotic foods and supplements can help restore, replenish, and maintain a beneficial balance of bacteria in the gut. These good bacteria outcompete bad bacteria and can help stop undesirable organisms sticking to the walls of the gastrointestinal and genitourinary tracts.
The two main types of probiotics in the human gut are lactobacilli and bifidobacteria, found predominantly in the small and large intestines, respectively. Every probiotic species and strain has a unique range of effects on our health.*
Probiotics work together to:
- Provide maximum support for acute digestive health needs* [1,2]
- Restore and maintain healthy, balanced intestinal flora*
- Help reduce antibiotic-associated digestive diarrhea and discomfort *[4,5]
- Support gastrointestinal integrity and support healthy inflammatory responses* 
- Stimulate phagocytes, dendritic cells, and other immune system cells to promote immune health* [7,8]
- Support the gut-brain axis and a calm, relaxed state of mind* 
A multi-strain formula, such as Natural Factors Ultimate Probiotic 12/12 Formula, helps maintain a healthy bacterial balance, while supporting digestive function.* If digestive upset does strike, a high-quality probiotic supplement can also help get you back on track by restoring intestinal balance.*
Some probiotic supplements, such as ReliefBiotic™ IB, are specially formulated to meet specific needs associated with urgent bowel discomfort, while others such as TravelBiotic® are helpful in cases of acute dysbiosis, when experiencing traveler’s diarrhea. Meanwhile, CalmBiotic™ contains strains clinically shown to support the gut-brain axis, helping to moderate feelings of occasional anxiety and promote a healthy mood balance.*
Many health professionals now recommend regular consumption of probiotics to maintain healthy gut microflora, as well as the use of probiotics when taking antibiotics, to restore gastrointestinal health and support immune function.*
The benefits of healthy gut flora extend far beyond the intestines, and are increasingly recognized as a key component of general health maintenance. Topping up your good bacteria can help keep your microbiome balanced, helping you maintain good overall health.*
We really can’t overstate the importance of gut health. An upset microbiome is no small thing! If you have any concerns about gut health, consult your health professional.
