Nutritional Testing

Nutrition is a critical and often overlooked part of preventive health and treatment. Your food is your fuel for health and life. The wrong diet can lead to diabetes, cardiovascular disease, obesity, high blood pressure and chronic inflammation. Dr. N. Johnson will perform a complete nutritional analysis and test your metabolic rate to see how efficiently your body uses your fuel. We use GENOVA Labs to test for the patient's most common food sensitivities. Food sensitivities are often overlooked as possible causes for a multitude of health problems. Dr. Johnson will help you eliminate your food sensitivities and the health problems they create. Other tests include:

  • Cleveland HeartLab® (CHL) is the advanced lab testing done with your physical and follow-up visits.
  • The CHL lab test can identify cholesterol problems, thyroid imbalances, vitamin D deficiencies, low omega 3s, excessive carbohydrate and sugar intake, inadequate exercise levels, and more.
  • Should a nutritional deficiency be found, such as low vitamin D or low Omega 3s, we have nutritional supplements that can be purchased onsite.
  • Additionally, we can check for mutations in the MTHFR gene. MTHFR is a gene that produces an enzyme that converts folic acid in your food into active forms your body can use. These active forms help create neurotransmitters that stimulate your brain to think, learn, sleep, and even express your emotions. Mutations in this gene may be linked to a wide-ranging set of symptoms, including: fatigue, anxiety, ADD/ADHD, foggy thinking, addictions, fibromyalgia, pulmonary embolisms, miscarriage, schizophrenia, severe depression, cancer and autism. 
  • A saliva cheek swab test can be used to identify the most effective and the ineffective medication choices for you.
  • Heavy metal testing can help confirm or rule out toxic levels.
  • Stool testing can help identify parasites and overgrowth of bacteria.

Food Sensitivities

Dr. Johnson uses Genova Labs Food Sensitivity testing.

The "IgG Food Antibody Assessment" is a food sensitivity test which helps identify those with true IgE-mediated allergies as well as IgG-mediated food sensitivities. This immunological food sensitivity test measures IgG antibody levels to 87 foods, and total IgE. Additional sensitivity tests are also available for regional inhalants, molds, vegetables, and spices. This antibody food sensitivity test is ideal for patients who may suffer from delayed reactions or sensitivities to specific foods. It may also provide insight on intolerances, or non-immune responses, to certain foods.

Why use the food sensitivity test?

The incidence of food sensitivities has increased dramatically over the years. It is estimated that up to 20% of the population have post-infectious Irritable Bowel Syndrome (IBS), adverse reactions to foods, and NSAID enteropathy.
Increased total antigenic load related to food and environmental sensitivities has been associated with a wide range of medical conditions affecting virtually every part of the body. Mood and behavior, including hyperactivity disorders in children, are profoundly influenced by food allergies.

IgG-Mediated symptoms may include:

  • Asthma
  • Arthritis
  • Migraines
  • Ear Infections
  • Eczema
  • Sinusitis
  • Urticaria
  • Colitis 

Dr. Johnson also uses the Genova Food Sensitivities lab to test you for:

  • Gluten/gliadin sensitivity
  • Casein or whey dairy sensitivity
  • Candida albicans (yeast) sensitivity

Gut Health

The digestive system is one of the cornerstones of our well-being, as it is involved in so many processes, starting with the optimal digestion, absorption and assimilation of food.  The health of your digestive system, or gut, determines what nutrients are absorbed and what toxins, allergens and microbes are kept out. Therefore it is directly linked to the health of the total body. So the common symptoms of poor gut health can be:

  • Irritable bowel
  • Bloating, constipation
  • Diarrhea
  • Heartburn
  • Reflux
  • Gas 

If our gut health is poor, we can end up with impaired immune and nervous system functions and altered hormonal function throughout the body. This is because our gastrointestinal tract is loaded with neurons that release the same neurotransmitters found in the brain. This is why you have “gut feelings” and any upset to this equilibrium can put your body and mood into chaos. Most of us do not recognize that digestive problems can cause havoc over your entire body, leading to allergies, arthritis, autoimmune disease, rashes, acne, fatigue, mood disorders and more.

Here at Dr. Johnson’s office, we understand that much of your wellness begins with your digestion. Let us work to improve your gut health and bring you to optimal wellness.

Fatigue

Fatigue is a common term that describes a general feeling of tiredness and lack of energy. Fatigue is often accompanied by:

  • Brain fog
  • Memory loss
  • Difficulty concentrating

Fatigue is also a plague of epidemic proportions in the United States. In some cases, fatigue is a symptom of an underlying medical problem that requires medical treatment. Most of the time, however, fatigue can be traced to one or more of your lifestyle habits, oftentimes related to unhealthy eating. If your fatigue has persisted for two or more weeks despite making an effort to rest, reduce stress, choose a healthy diet and drink plenty of fluids, you should call and make an appointment.

If you have not had a physical within the last year, we will suggest a physical exam with our advanced lab testing to provide a current picture of your health status. Dr. Johnson and his staff will review these results with you. Additionally, Dr. Johnson's nutritional testing may be suggested to pinpoint any sensitivities in your diet. His nutritionist will meet with you and provide nutritional consultation that will help overcome your fatigue and let you live your life with more vitality. Possibly, low vitamin D, iron or B12, excessive simple carbohydrates (breads, cakes, pastries, pastas, crackers, etc.) or food sensitivities are the cause, so we evaluate your individual issues and provide instruction and a plan to eliminate the fatigue.
