Let Them Eat Dirt

We interviewed Dr. Arrieta a few years back about here book, Let Them Eat Dirt. It seems timely to discuss why building your immune system is so important today and for the rest of your life. My recommendations for having a healthy immune system are: eat organic, drink clean water, heal your microbiome (gut), mitigate your exposure to EMFs as much as possible, exercise, laugh, heal your childhood, be grateful and make a choice every day to enjoy your life.

Read and listen below to learn why we do not recommend using hand sanitizers.

In the 200 years since we discovered that microbes cause infectious diseases, we’ve been battling to keep germs and dirt at bay. In the past 10 years, there has been extensive research and evidence in the scientific community that our over emphasis on killing germs and our hyper-cleanliness is taking a toll on our health, and especially the health of our children.

Food Integrity Now interviewed Dr. Maire-Claire Arrieta, co-author of the book, Let Them Eat Dirt, How Microbes Can Make Your Child Healthier.  In this interview (interview here), Dr. Arrieta talks about how living in an over-sanitized world can create health issues in our microbiome (gut) and how important it is during the first 5 years of life to balance the microbia in our gut.  She shares how diet affects the microbes in early childhood and the importance of adding whole foods and fiber as a part of that healthy diet. She talks about breastfeeding–even after solid food is introduced–and how that can assist the child’s immune system.  Arrieta spoke about the research on vaginal births vs. cesarian and how the early introduction to these important microbes can affect the child’s immune system.

 In her book, Let Them Eat Dirt, Arrieta shares some of the research that she and Dr. Finlay, her co-author, have done on the importance of creating a healthy immune system in the first 5 years of a child’s life. She also offers suggestions to parents who have older children and what they can start doing now to give their child the best diet and lifestyle to create a balance in the important microbes that are necessary for a healthy immune system. She further discusses the overuse of antibiotics and how they can affect a child’s immune system.

  1. This looks like a very interesting read and an eye-opener. I remember I always got a lot of scolding from my mom when I was still a kid when playing in the mud. It would’ve been a different story for me if this book came sooner. Still, this can make things better for my kids. Thanks for sharing!
