Are you struggling with unresolved wellness issues?

Food sensitivities could be causing the majority of your wellness issues.

Here are some comments from three people who have removed the foods from their diet they had a sensitivity to. Jackie, Kevin and Katlyn:

“I was working out 4-5 times a weeks and eating healthy for the past 2 years in order to lose just a few pounds, but it was not happening for me…Just by eliminating 3 foods out of my eating routine I was able to lose 10 pounds in about 3 weeks…I am happy and I am healthy!” -Jackie


“I have been struggling with what I thought was a gluten sensitivity for a while now. But no matter what I did my symptoms continued. When I discovered food sensitivity testing I jumped at the opportunity. Why not, it’s noninvasive and inexpensive. Here come to find out I have a sensitivity to yeast. Gluten is not an issue for me, it’s been yeast all along. If it wasn’t for food sensitivity testing I would of continued being misdiagnosed and suffering.” -Kevin


“It’s been 30 days since taking out the foods I’ve been shown to have a sensitivity to. I am acne and eczema free! There is still a patch drying up on my leg but it’s getting better. No IBS symptoms either. I’m a happy Girl!!” -Kaitlyn

What are some of the symptoms of Food Sensitivity?

If you are struggling with any number of these symptoms you may be experiencing a sensitivity to foods you are consuming:

  • Dry and itchy skin
  • Food intolerance
  • Feeling bloated after eating
  • Fatigue
  • Migraines
  • Headaches
  • Gastrointestinal (GI) distress
  • Stomach ache/pain
  • Acne
  • Eczema
  • Dry and itchy skin
  • Bloated stomach after eating
  • Joint pain
  • Chronic Pain / Inflammation
  • Other skin problems
  • Diarrhea
  • Depression and mood swings
  • Runny nose
  • Reflux
  • Trouble sleeping
  • Dark circles under eyes
  • Weight Loss Resistance
  • Thyroid Dysfunction

We have all used fad diets to try to lose weight and regain wellness. The problem with most diets is they try to exclude whole food groups. What we want to do is only exclude specific foods that you have a sensitivity too.

You may be avoiding foods you love, that you could eat.

You may be eating something that you believe is healthy for you but in fact could be causing you harm.

There is only one way to know for sure. That is to get tested. Why guess when you can know!

A quick word from Tammy and Bill!

“After removing the food items that I tested intolerant to I dropped about 4 pounds! This happened in just 2 days! Although this wasn’t weight loss from fat but from bloat and/or inflammation the foods were causing. I am feeling much better.” -Tammy Schrecengost

“I was not aware that one thing I was eating everyday was making me feel horrible! I am so glad I was tested!” -Bill Haymaker

What is a Food Sensitivity?

A food sensitivity is different from a food allergy.

A food allergy happens in the bloodstream and has an immediate, sometimes life threatening reaction, requiring immediate medical attention. Most people with these kinds of allergies often carry with them an EpiPen to counteract the reaction of a food allergy. An example and one of the most common would be like a peanut allergy or shellfish allergy.    

A food sensitivity however is much different.

A food sensitivity or a food intolerance is caused by an inability to digest a food and occurs in the digestive tract. The body cannot completely digest a particular food, and the proteins of this food enter the bloodstream un-dissolved and cause an immune system reaction.

This is why food sensitivity symptoms are so vast. Depending on the person It can happen with any food and depending on the food it can cause a reaction anywhere in the body.

Why is it so difficult to identify the food causing the sensitivity?

Symptoms of a food sensitivity may not show up for 72 hours making it almost impossible to identify the food causing the issue.

You would have to eliminate a food and wait at least 3 days, but what if it’s in a food substance like gluten, or an additive that’s in many foods. This makes it virtually impossible to identify a food sensitivity on your own without testing.

How does someone get tested for food sensitivities?

One option is to draw some blood and have it analyzed by a laboratory. You can either go to a Doctor’s office and have this done. Or there are mail order options. 

As you could imagine Doctor visits and/or lab work can be extremely expensive. And there is nothing pleasant about drawing blood.

Another option is muscle testing. (This is NOT muscle tissue testing) This is a noninvasive inexpensive alternative to blood and lab work.

What is muscle testing?

Muscle testing is a muscle resistance test. Your muscles ability to resist counter pressure when your body is introduced to a substance it has a sensitivity to.

If there is no sensitivity the muscle will stay strong. However if there is a sensitivity the muscle will go weak.

Has a medical doctor ever pushed against your arm or leg and asked you to push back to test the strength of you muscle, or even ask you to squeeze his finger in your hand?

It’s that simple.

Of course I will explain in full detail during our visit. It’s just not possible to give a full explanation in text.

However; with muscle testing you will have your answer immediately, no doctors office visit, no blood, no waiting on lab results, and no expensive lab fees.

A Testimonial from Becky

Hello my name is Becky, I’ve been feeling really bloated & gross lately, having breakouts and just all around feeling pretty sick. I decided that I was going to start eliminating foods out of my diet to see what was causing the problem. The next day I found out about food sensitivity testing. This can help you discover what foods are making you sick or even overweight! Just like you, my health is really important to me and I really want to know what foods to avoid to help me feel better, this is so worth it.

What Causes a Food Sensitivity?

Too much of one food. You can become sensitive to any food you eat too often. Many people eat a relatively small number of foods several times a day. For example, wheat, a common food sensitivity, is found in breakfast cereals, the bread used to make a sandwich at lunchtime, and the spaghetti eaten at dinnertime.

Leaky gut syndrome. The digestive tract plays a vital role in preventing illness and disease by providing an impenetrable barrier. When the lining of the gut is inflamed from a food sensitivity, small openings develop between the tightly woven cells making up the gut walls. This is called “leaky gut syndrome”. With leaky gut syndrome, partially digested dietary protein can cross the intestinal barrier into the bloodstream. These large protein molecules can cause an allergic response, producing symptoms directly in the intestines or throughout the body. Additionally, hundreds of yeast and bacteria are released from the gut into the bloodstream where they set up infection anywhere, including muscles, joints, bones, teeth roots, coronary arteries, or even the brain. The early introduction of solid foods to infants before six months of age contributes to leaky gut syndrome and subsequent food allergies and sensitivities.

Deficiency of Probiotics. One of the causes of leaky gut is an absence of probiotics or ‘friendly’ bacteria in the intestines. The friendly bacteria help maintain the health of the intestines by producing fuel for intestinal cells and killing bad bacteria. Parasitic infections, treatment with antibiotics and other toxic pharmaceuticals, stress, poor diet (sugar and flour), smoking, alcohol, excessive hygiene, candida overgrowth and bottle-feeding your baby can disrupt the proper balance of friendly bacteria to bad bacteria.

Overworked immune system. Constant stress, exposure to air and water pollution, and pesticides and chemicals in our food puts a strain on our immune system, making it less able to respond appropriately to the antigens in food.

Genetics. Food allergies and intolerances seem to be hereditary. Research indicates that if both parents have allergies, their children have a 67% chance of developing food allergies. When only one parent is allergic, the child has a 33% chance of developing food allergies. Specifically, a person may inherit a deficiency of an enzyme like lactase, the enzyme that digests dairy. With nightshade sensitivities, there are ten genetic variants for susceptibility, not all individuals are affected equally or at all. A similar case can be made for other food sensitivities. Genetic variations predict the severity of your sensitivity.

How Can Food Sensitivities Destroy Your Health?

INFLAMMATION is one of the biggest drivers of weight gain and disease in America. Heart disease, cancer, diabetes, high cholesterol are ALL inflammatory based conditions. Food sensitivities cause systemic inflammation throughout the body, beginning in the gut. For exmaple, in people with gluten sensitivity, the immune system attacks the intestinal cells to which gluten attaches, inflaming the gut. And, when the lining of the gut is inflamed, the body is prone to even more food sensitivities and reactions, and the problem spirals out of control. The other important thing to remember is your small intestine is where you absorb your nutrients. So if you’re sensitive to gluten, this destroys your small intestine leading to nutrient deficiencies. It’s the nutrient deficiencies that can lead to a whole host of symptoms and conditions. This is one other reason why we test for deficiencies if you are indeed intolerant to gluten. 

The other problem is that most people eat foods they have become sensitive to several times a day. Every time that food enters the body, the immune system whips itself into a frenzy. But because symptoms are delayed up to 72 hours after eating, a food sensitivity can be hard to spot. Without a food sensitivity test, the damage is repeated over and over, meal after meal. Eventually, inflammation seeps throughout the body, establishing an environment ripe for weight gain and chronic disease.

A quick word from Debora and Jesse

If you’re experiencing difficulty digesting foods and have symptoms such as bloating, IBS, headaches and unexplained weight gain you may have a food intolerance. I was experiencing the above symptoms with many of my meals so I decided to try a food intolerance test. Since getting my results I’ve removed those foods and within 10 days my symptoms have significantly improved. I wanted to share that I am very pleased with my results and would highly recommend food sensitivity testing to anyone who suspects they have a food intolerance.Deborah


I feel great ever since I took a food sensitivity test and found out my food intolerances ( and obviously, cut them out of my diet ), no headaches, bloating, mid-day slumps or breakouts. If you have a food intolerance, even healthy food can have terrible effects on your body. It’s only been a few weeks since I’ve adapted my diet and I feel SO GOOD.Jesse

What Food Sensitivities will I be Tested for?

I test for 158 foods and 31 food additives 189 total items

For a full list of food items we test for click here.

Compare that with one of the most popular mail in products on the market today. With these mail in food sensitivity testing products you must draw blood. With my service there is NO drawing blood. They test for only 96 foods. I test for 158 foods and 31 food additives 189 total items for only $150.00

Another popular mail in product we can compare also requires drawing blood. Again with my service there is NO drawing of blood. They test for 200 foods, I test for 158 foods and 31 food additives 189 total items. Their fee is $380.00. My fee is only $150.00. But to be fair, I do test 11 substances less. So let’s look at cost per item. There cost per item is $1.90. My cost per item is only $0.79 cents.

What about supplements?

It is extremely important to test any supplements you may be taking. For many people supplements are a huge part of their wellness regimen. It can also be very expensive. It’s very important to do a nutritional supplement evaluation. We can determine exactly what supplements you need and exactly what supplements you don’t. We can even test dosage on the supplements you do need. This will maximize the investment you are making in your health.

A quick word from Jason, Brook, and Joseph

I tend to get non-life threatening reactions to various foods. The idea was to track down what foods cause skin rashes and what food cause gastrointestinal issues and so forth. I tested with sensitivities to a large number of foods. I found this interesting and also discouraging. With so many foods listed it’s impossible to cut all these items out known as an elimination diet. This test did help me realize I have food sensitivity reactions to many food items and that’s just me. -Jason

Reply from Dr. Jeff – “Don’t despair, when people test a sensitivity to multiple foods it’s generally a deficiency in digestive enzymes and good gut bacteria, an issue easily fixed.”

I took a food intolerance test a while back and it has literally changed my life. Turns out I didn’t need to avoid gluten but some of the other additives found in a surprising amount of breads like SOY and SESAME. I also used to eat hummus like it was going outta style…fyi: tahini=sesame. I am no longer uncomfortable digesting food NOR am I constantly bloated!! I feel great! Brook

I had taken allergy skin tests before; But a food sensitivity test is far better! I feel better, healthier & more normal since dropping the foods that I have a sensitivity to. I’ll be testing one more time to ensure I’m still on the right path.Joseph

Here are 5 more people experiencing great results!

Heather,

I was in disbelief when my results came in. I am highly intolerant to garlic and peanuts. I honestly was using garlic in pretty much every dish I prepared and ate peanut butter every day. However, since cutting out garlic and peanut butter, I have felt more energetic and feel my eczema has had significant improvement.


Nicole,

“Discovering my food sensitivities has truly changed my life! Many of the foods I ate on the daily basis came up as intolerances. The past two weeks, after cutting out my problem foods, I’ve never felt better. I will be forever grateful for this test”.

Andrew,

Who would of thought food sensitivities were causing my chest pains. I found that 2 things I was consuming daily I tested sensitive too.  After eliminating these from my diet for just 3 days I saw results on my facial redness and in the inflammation in my chest.

Trish,

Prior to the test, I had been having just about one bladder infection per month. I am happy to report that after dropping those foods identified in my food sensitivity test, I went a full 8 months without an infection!”

Michelle,

“I had no idea I was intolerant of peanuts or coconut, but I experimented with not eating them for a couple of weeks and my skin TOTALLY cleared up, even the eczema on my arms. And my digestion and energy levels have improved so much!”

All names have been changed to protect doctor-client confidentiality.
