Leaky Gut, Your Microbiome, and Food Sensitivities

Remember the days when bacteria was decidedly all bad? We used antibacterial soaps in the shower, bleached (or use lysol on) every surface in the home. We used antibiotics much more often than now.

Well, gone are the days of the indiscriminate war on bacteria. Now, scientists are vigorously sussing out the differences between good and bad bacteria, and specifically, the roles of each.

We are learning that we need our bacteria to stay alive and well.

You’re probably hearing a lot on the internet lately about “microbes” and “microbiome” and “gut health”. But what do these terms really mean, and how do they impact your health?

Microscopic life forms, or microbes, are everywhere: in the soil, in the water, on animals, on your skin and inside your body. They live in your nose, your mouth, your digestive tract, your hair, your genitals, your ears, and even your eyes! Microbes cover every surface of our bodies, both inside and out. They outnumber our own cells by about 10 to 1, and there are thousands of species of them.

The collection of your microbes are known as your microbiome. Your microbiome’s genes have about 100 times more genes than you have in your own genome! This influences your immune system, your weight, your mood, any food sensitivities or allergies you develop, and much more.

As you can imagine, it’s really important to be a host to the nicest, most health-promoting microbes that you can find.

Many scientists view our microbes as a newly discovered organ with much to learn from, as its incredible functions are both complex and essential for life.

In today’s episode with Susan Linke,  guest expert on food sensitivities and functional nutrition, we’ll cover the following as it relates to your microbiome and gut health:

1.     What is your microbiome, and how does it influence on your genes?

2.     How does this influence “leaky gut”, or a permeable gut membrane?

3.     How are the immune system, gut health and depression linked?

4.     How are food sensitivities and microbiome linked?

5.     How is muscle pain triggered by food sensitivities?

Labs mentioned:

  • Oxford (provides the MRT food sensitivities test)
  • Spectracell (provides micronutrient panels and much more)
  • Cyrex
