The Allergy Solution, now an international best-seller


Allergic disorders have become the #1 most prevalent disorder worldwide

One billion people suffer from allergic diseases such as asthma, hay fever, eczema, and food allergies, and this is just the tip of the iceberg. What was once thought of as the rare and exceptional has now become the norm, and in light of this, we are forced to ask ourselves an important question: how did this happen, and what can we do to fix it. For the solution, look no further than the environments we have built for ourselves and our bodies, the outdoor, the indoor and the internal.

Outside our homes, our environment, thanks in part to ourselves, has undergone drastic changes, ranging from a general increase in air pollution, including diesel exhaust and ozone, to harmful climate change. Science has already shown how, working together, these factors have increased the prevalence and severity of allergy.

    “Dr. Leo Galland and Jonathan Galland have put together a masterful and critically important discussion about allergies.

This book provides astounding wisdom about the world of allergies to the reader searching for health answers. I truly enjoyed reading it and picked up a lot of information I had not heard before. Terrific job!”


And as we exist in this toxic outdoor environment, we bring more and more of these harmful allergens in to our own home, be it on our clothes, the soles of our shoes, or in the cars we have in garages attached to our house. What was once a safe heaven is now a hotbed of allergy. Further, the use of household pollutants and toxic chemicals, which can take the form of seemingly inconspicuous products like household cleaners and detergents, adds another entry point for the harmful chemicals that can cause allergy. View the science behind The Allergy Solution here.

Finally, we’ve thrown off the balance of our internal environment. That is, the balance of the microbes and nutrients within our very bodies. It may be hard to believe, but allergies start in your stomach. The trillions of bacteria that naturally live in your body have an immense effect on your immune system, and these very bacteria influence how allergic you are. By consuming a nutrient deficient diet that is rich in harmful sugars and GMO-laced foods, you risk dysbiosis of the gut, a harbinger of allergies.
