Proper Nutrition is Essential for Health 

Proper nutrition is essential for maintaining health, preventing disease, and restoring health in the face of disease.
Medical Nutrition Therapy, seeks to improve health and symptoms naturally by optimizing patient nutrition, thereby decreasing the need for medications.

  • The balance of nutrition is unique to the individual and can vary depending on diet, digestion/absorption, age, race, gender, lifestyle, medications, and state of health or ill health.

  • The common symptom in every disease is the loss of health, and it's the one symptom doctors often fail to treat. Yet any symptom can be made worse if the nutrition is insufficient to maintain health or promote healing.

  • Nutritional deficiencies are common in chronic and degenerative disease or after trauma injury or surgery.

  • Medications can't correct for nutritional deficiencies, and improved nutrition can't correct for medication toxicities (side effects). Long term use of medications increases the risk of side effects which are usually treated with more drugs. Medical Nutrition Therapy can improve symptoms naturally which may decrease the need for some medications.

  • Self-care is the most important part of healthcare, and proper nutrition is the foundation for health; without which you can't obtain adequate exercise, quality sleep, adapt to stress, detoxify or maintain the body's tissues.
