Since our gut health is crucial for our overall health, it would be best to avoid whatever it is that can hamper the growth of our good bacteria. If gut bacteria has been altered or is out of balance, imagine what effects it will cause to your body when it is unable to function properly.
Just as there are things that we consume that can aid the growth of the good microorganisms in our body, there are also things that can hamper the balance and growth of good bacteria in our microbiome.
Antibiotics can alter your microbiota and the effects can be long term if not remedied. It does not discriminate between bad bacteria that is wreaking havoc in your body or good bacteria that belongs in your gut and inevitably wipes out both from your system. Therefore, avoid self-medicating or unnecessary medication if possible.
It is well known that sugar can cause diabetes and obesity, but did you know that sugar also negatively affects your gut microbiome? Consuming high amounts of sugar (including artificial sweeteners) is seen to increase the amount of bad bacteria in the gut that is associated to gut and brain inflammation as well as liver disease. It also affects your cognitive ability.
Any artificial or synthetic food additive alters the intestinal mucous. Since it alters your gut microbiota, it also causes inflammation. These can cause weight gain, increased appetite, increased fat mass, and metabolic syndrome. It also puts you at risk of type 2 diabetes, heart disease and stroke.
