YES! Your Diet Affects Your Gut Microbiome

Back in 2004 when documentary filmmaker Morgan Spurlock ate nothing but junk food for an entire month while filming ‘Super Size Me’ it made headlines. You see, Morgan’s experience revealed an alarming reality. Most notably, a fast food diet can quickly trigger serious health issues.

After a very short time the documentary filmmaker noticed his energy levels plummeted, he packed on weight, and his liver was at serious risk. In short, the extreme Super Size Me diet challenge highlighted the very clear link between junk food and obesity, cardiovascular disease, diabetes, and many other chronic health conditions.

Thankfully, these days we now have a far greater understanding of the potential harm caused by consuming too much junk food, especially in regards to the health of the gut microbiome.

The gut microbiome is a term used to refer to the complex mini-ecosystem within your digestive tract. By and large, it plays a major role in your overall health.

Looking back, I think it’s very likely Morgan did some pretty serious damage to his gut microbiome.
