Linda Slater-Dowling, CNHP

Linda Slater-DowlingLinda has owned and managed several businesses over the past 20 years, and has 25 years of experience interacting with the natural health industry. Natural health and nutritional remedies are Linda’s life passion, and we are so excited to be able to share the remarkable health powers of all-natural organic foods and health products with all of you.

Linda, having experienced firsthand the negative health effects of contaminants while visiting New York in 2002, has since made it her mission to help others find healthy, natural ways to heal. Her dream is that one day, affordable health foods and supplements will be available to everyone.

Natural health and nutritional remedies have been Linda’s life passion for the last 19 years. We are so excited to be able to share the remarkable health powers of all-natural organic foods and health products with all of you. The creation of Nutritional Institute’s STUDENT FORMULA BRAIN BOOST™ product has truly been a labor of love for Linda, one that was preceded by almost two decades of study with a naturopathic physician, and spurred by her own triumphs using natural foods to heal.

Linda’s Story:

Having experienced first-hand the incredible benefits of what I call a “natural, organic lifestyle” is what’s given me the tenacity and desire to share this gift with others. In 2002, I traveled to New York City to take a 50-mile bike ride around the city. At the time, I was in good health (and had been following a healthy lifestyle for years), but that all soon changed. Our hotel happened to look out directly over Ground Zero, and I recall being astonished that the streets were still being watered down to remove debris, and somewhat awestruck at the massive construction efforts going on.

By the time I returned home, I had become extremely ill; I believe due to some type of contaminant I was exposed to near Ground Zero. My esophagus felt burned, I couldn’t breath, I had developed severe acid reflux and as a result hated to eat. Soon I lost a lot of weight and developed pneumonia that persisted for months because my immune system was too weak to fight it off. I felt at times that I wouldn’t make it. And, all of this had developed, quite literally, overnight!

Well, all of the tests and drugs that mainsteam medical doctors could give me did not make me better. What did heal me, and now, years later, has gotten me almost completely back to normal, was following an intensely healthy diet that included vegetable juicing several times a day, taking plenty of digestive enzymes and eating soothing aloe vera after meals. And I am not alone. I have seen similar miraculous results in others facing different health challenges who adopt healthy lifestyles.

My Philosophy:

I’m optimistic. I’m not here to focus on disease, but rather on the prevention of disease-using natural foods, healthy products and all-natural remedies. If we held a nationwide vote, my guess is that most people would inherently choose to have healthier foods (the kind without added hormones, pesticides, antibiotics, trans fats, etc.) and a cleaner environment. But the reality is that many Americans, despite living in the most prolific country in the world, do not have access to the very things that will keep them well: pure, healthy food and a clean, non-toxic environment.

It is my sincere belief that we can change this by helping one person at a time to adopt a healthier lifestyle, and together ultimately build a cleaner, healthier world..

My dream is that one day, affordable health foods and supplements will be available to everyone, but I have established this Web site for students because our future begins with them. The young adults of today have the power to demand a change in the way our food is grown, the way our health is treated and the way our very environment progresses tomorrow.

In short, we need to transform our worldview into one that values what nature has to offer over what scientists can create. I like to use dandelions as an example. Few people know that these “weeds” are incredibly healthy for the liver, gallbladder, kidneys and digestion. But, rather than valuing these plants, we kill them-typically with highly toxic chemicals-and choose instead to value our artificially created green lawns.

Our Student Interns

The Nutritional Institute is pleased to have had many wonderful interns throughout the years who have been worked diligently on our new radio shows, products, and in various other ways for our company.

Our Intern Program has allowed students from many backgrounds such as English, Web Development, Fine Arts-Visual Communications, Industrial Arts, Information & Decision Science, Law, Marketing, Advertising, Computer Science, and Finance to learn more and build new skills.

These students have come from University of Illinois Champaign-Urbana, DePaul University, Northern Illinois University, College of Lake County, Loyola University, and University of Illinois-Chicago.

We are very grateful and thankful to have had so many wonderful students working with us!
