Identify Harmful Bacteria and/or Food Sensitivities and Access Functional Nutrition Counseling

“The road to health is paved with good intestines.” – Sherry A Rogers


Many patients come to us simply feeling unwell. And they’ve gotten used to this as “normal.” Do you experience any of the following symptoms?


  • Bloating and cramping
  • Migraines
  • Chronic fatigue
  • Chronic discomfort
  • Painful joints
  • PCOS and fertility problems
  • Reaching a weight plateau


 The connection between autoimmune diseases, migraines, and other chronic health problems and food sensitivities, allergies, and intolerances isn’t always clear. By identifying the underlying causes of your discomfort, you can live a healthier, more vibrant life.


It’s important to understand the differences between allergies, intolerance, and sensitivities.


What are the signs and symptoms of a food allergy?


Food Allergies: Allergies are the body’s immune system’s reaction to “harmless food.” The body is trying to protect you, and in doing so, the reaction can be immediate and deadly. Allergy symptoms include rashes, swelling, breathing problems, and light-headedness. If experiencing this, you should get to a doctor immediately.


As online nutritionists and dietitian counselors, the best way to help keep you safe is by teaching you how to read food labels, so you can identify all those hidden ingredients. It’s important to read food and cosmetic labels each time you buy an item, as food companies can change the ingredients of products without notice.


What are the signs of food intolerance?

Food Intolerances: Intolerances are the body’s inability to process or digest a certain food. (The body’s digestive tract doesn’t make enough of a specific enzyme to break down the food in the body.) A food intolerance affects your body’s digestive system, whereas an allergy affects the body’s immune system. 


Common intolerances include lactose (dairy products), caffeine, gluten, histamine, and salicylates. Many can relate to feeling bloated, gassy, having diarrhea, and other symptoms related to food intolerances. 


What are the signs and symptoms of celiac disease?


Celiac Disease: Celiac disease is not an intolerance, allergy, or sensitivity. It’s an autoimmune disorder that is very serious. Consumption of gluten triggers a complex inflammatory reaction within the body’s digestive system, leading to significant illness. It’s important to note that a single instance of consuming gluten won’t induce this reaction; however, people with Celiac disease may develop issues such as weight loss, malnutrition, and other severe digestive problems over time.  Though people might have gluten intolerance, only 1% of the population has Celiac disease.


Reach out to your primary care physician if you have any doubts about whether you have celiac disease. As dietitian nutritionists, we can work with your medical team to ensure you get the nutrients you need on your new diet.


What are the most common food sensitivities?

Food Sensitivities:
Identifying food sensitivities can be challenging. You may experience joint pain, migraines, brain fog, rashes, chronic pain, bloating, and gas, among others. Adding to the complexity is the timeline factor. In contrast to allergic reactions, which manifest immediately, sensitivities can emerge anywhere from 24 to 72 hours after consuming specific foods. The severity of sensitivities is also influenced by the quantity of the food consumed. Opting for food sensitivity testing (the Pinnertest) can assist in pinpointing the specific foods and chemicals contributing to your discomfort, followed by an elimination diet protocol to help you understand which foods and how much of these foods your body can tolerate.


If you are feeling unwell, it’s not in your head. Your body may be reacting to your food choices. By working with an RDN, we can get to the WHY. Functional nutrition therapy can have a substantial impact on your well-being.


We will ensure that you continue to receive essential nutrients while eliminating trigger foods, and we will craft a comprehensive, individualized nutrition plan to support you.

What is the Gut Zoomer Test?

The Gut Zoomer sensitivity test is a stool examination designed to evaluate bacteria, yeast, viruses, and parasites within the gut microbiome, along with pertinent digestive and inflammatory markers. This comprehensive panel simultaneously measures hundreds of microbial species, making it the most extensive digestive health test currently available.


Why take the Gut Zoomer test?


As functional dietitian nutritionists, our focus is always on understanding the “why.” This test is invaluable as it provides invaluable information to tailor nutrition interventions to help heal your gut. Are you experiencing any of the following issues?


• Autoimmune conditions • Inflammatory Bowel Disease (Crohn’s and ulcerative colitis) • Irritable Bowel Syndrome (IBS) • Celiac disease • Cardiovascular disease • Metabolic Syndrome • Diabetes • Liver and gallbladder disease • Neurological disorders • Mood abnormalities • Skin rashes (eczema or dermatitis) • Inflammatory symptoms • Small intestinal bacterial overgrowth (SIBO) • Fatigue • Gas and bloating • Indigestion • Infections • Intestinal permeability (‘leaky gut syndrome’) • Nutrient deficiencies • Food sensitivities • Malnutrition

What is the Food Sensitivity Pinnertest?

The Pinnertest, a finger-prick food sensitivity test, helps identify your body’s reactivity levels to various foods and chemicals—whether reactive, moderately reactive, or non-reactive.


Collaborating with one of our Registered Dietitians allows us to formulate a personalized diet addressing your unique needs, aiming to reduce or eliminate foods causing discomfort. Through guided nutrition therapy, regain empowerment over your food choices and embark on a journey towards a healthier you, one bite at a time.


Why choose the Pinnertest for food sensitivities or intolerances?

• Weight Gain • Tiredness or Chronic Fatigue • Migraine and Aches • Bloating and Edema • Joint Pain • IBS – Irritable Bowel Syndrome • Skin Problems
