While many would like to discover the fountain of youth, the secret to aging gracefully might lie, in part, in our gut.

Although researchers now know that the gut microbiome changes as humans age and that age-related diseases may also affect the gut microbiome, how targeting the gut microbiome may lead to healthier aging or reduce the risk of age-related diseases it is still unknown. Besides genetics, diet and other lifestyle factors such as medication use and social interactions, the gut microbiome may therefore be a key factor in healthy aging.

There has been a recent explosion in research that shows that our gut flora is linked to so many diseases-- cancer, autism, diabetes, heart disease, Alzheimer’s-- and the list goes on and on.

The microbes that inhabit our guts consist of about two million genes compared to only about 22,000 genes humans have, and they’re constantly affecting our health.

You can think of our gut microbiome as a rainforest. The more variety and number of species that inhabit our guts, the healthier the ecosystem of our intestinal flora will be.

The infant gut microbiome is characterized as low in diversity that’s dominated primarily by bifidobacteria and unique to the individual. During approximately the first three years of life, the gut microbiome develops and is largely shaped by various factors including delivery mode (vaginal vs Cesarean birth), maternal antibiotic use, home environment and breastfeeding vs formula feeding. The gut microbiome is later influenced by diet and how long the child was breastfed which affects the gut microbiota composition later in early childhood.

Several recent studies have shed light on the benefits breastmilk have on infant health and their developing gut microbiomes because it contains various components, such as beneficial bacteria, prebiotics called human milk oligosaccharides as well as immune cells, that confer long-term benefits for babies’ health including preventing malnutrition. Additionally, breastfed babies have been found to have less instances of allergies and metabolic disease, yet it is unknown how breastfeeding practices (i.e. nursing vs. pumping) affects the breastmilk composition and infant gut microbiome.

Pumping breastmilk has become a popular and convenient way for mothers to continue to feed their babies breastmilk, yet it is unknown as to whether this method affects the transfer of other non-milk-derived bacteria from the pump or bottles compared to maternal skin for example.

The importance of maintaining a healthy gut microbiome has been gaining more attention. 

The gut microbiome contains trillions of microorganisms, most of which are bacteria, and plays a major role in various aspects of our health. 

Probiotics and fiber have gotten a lot of fanfare lately when it comes to gut health, but in order to feed the “good bugs” or beneficial bacteria in our intestines, we also need to eat adequate prebiotics. 

Unlike probiotics, prebiotics are not live microorganisms, and although most prebiotics are different types of fiber, not all prebiotics are fiber. So what are they?

Ever since I was a little kid I have had stomach issues- vomiting, susceptible to stomach bugs, gas, bloating, etc. You name it, I’ve experienced it.

Unfortunately, as I grew older into my adult years, I didn’t outgrow my sensitive stomach. I finally went to a gastroenterologist who concluded that despite my symptoms of heartburn, gas, bloating and diarrhea, all I had was a mild case of acid reflux for which he prescribed me stomach acid blocking medicine.

I left his office infuriated because I knew that an antacid would not solve my underlying digestive issues, so I started to do my own research about digestive health and the gut microbiome and the role diet and lifestyle play in overall gut health, which has led me to publish various peer review articles about the gut microbiome and overall health. With some dietary and lifestyle changes I healed my gut which has greatly impacted my overall health and energy levels.
