Insulin Resistance is an often silent condition that affects millions of
Americans.
As a factor that has previously been under-recognized by patients and
physicians, Insulin Resistance is an important precursor to the epidemics of
diabetes and cardiovascular disease.

Dr. DeLuca received her Naturopathic Degree and B.S. in
Nutrition from Bastyr University in Washington state. Her particular interests include research in the fields of nutrition, diet and nutrient therapies. She coaches Insulite Laboratories'customers on their insulin-related conditions through the company's comprehensive outreach program. At her practice in Kingston, Pennsylvania, Dr. DeLuca specializes in counseling as well as nutritional, botanical, orthomolecular and physical medicines.
One of the goals of Naturopathic Medicine is to find the cause of illness. With the rise of obesity, Type 2 Diabetes and Metabolic Syndrome, along with their many complications, research is revealing one of the main causes to be Insulin Resistance. Although important, it is not enough to just treat the symptoms. You have to treat the cause, too. A balanced, nutritious diet plan and a program of regular exercise are proving to be crucial to help reverse these diseases and allow people to regain control of their health.
I am very excited to be a part of a team that is making a difference in people's lives by taking a lead role in preventing and reversing Insulin Resistance.

I am committed to reversing the growing trend of Insulin Resistance that we see especially in the developed world. Insulin Resistance leads to many serious chronic conditions and is usually readily healed with lifestyle changes and nutritional supplementation. This is truly a modifiable health risk that healthcare practitioners have an obligation to address.

I look for the root cause of an illness or imbalance in a patient. With an increasing number of people being diagnosed with Metabolic Syndrome and Diabetes Mellitus, it is not surprising to see, at the same time, an increasing number of women being diagnosed with PCOS. All of these conditions have a common root cause, Insulin Resistance.
