Are your food sensitivities permanent?

When you consume enemy foods that your body cannot digest, they enter your bloodstream, causing inflammation, leaky gut, food sensitivities, and the many symptoms and diseases you suffer from.

The gut is the gateway to all diseases (find out why in this video).

Your immune system wants to neutralize or eliminate these enemy foods, and to do so, it produces, among other things, IgG antibodies.

Food sensitivities occur when an antigen—a fragment of the enemy food—binds to an IgG antibody; this reaction can be measured through a blood test.

Are food sensitivities permanent?

If, at the time of your Food Sensitivity Test, you remove those enemy foods according to your sensitivity level and replace them with friendly foods that work for you, you can heal your gut and may eventually be able to consume some of those foods again.

In some cases, and according to the Traffic Light System of the 3R Protocol:

Green zone: Even if some of these foods test positive, you will still need to remove them for a period of time. Most likely, once your gut is healed, they will no longer show up as positives in your next test.

Yellow zone: Even after healing your gut, you should retest using your food sensitivity test and place emphasis on rotating these foods to avoid becoming inflamed or sensitive again.

Red zone: Even if these foods do not appear as positive in your test, we recommend removing them as a lifestyle habit, because:

  1. They are inherently hard to digest and contribute to leaky gut
  2. You may be genetically sensitive to them, and this does not change over time
  3. They disrupt your intestinal microbiota

Examples include:

  1. Grains: Wheat, barley, rye, oats, corn, rice, sorghum, millet, teff
  2. Dairy: Especially cow’s milk products
  3. Sugar

Beyond the traffic light system, you should also consider:

  • The amount and types of food families you consume
  • Your lifestyle
  • Your medical and nutritional history

How often should you re-identify your sensitivities?

If you've already done your first test, your NutriWhite Consultation will help you decide the right time to repeat it, based on the parameters above.

If it's been more than a year since your last test, we do recommend repeating your Food Sensitivity Test. This will allow you to:

  • Adjust your nutrition plan
  • Safely reintroduce NutriWhite-approved foods
  • Make changes to your lifestyle

So you can make the decision to live better and say goodbye to illness!
