Food intolerances occur when your body struggles to break down certain foods, often due to enzyme deficiencies or gut inflammation. Unlike allergies, which trigger immune responses, intolerances develop gradually, leading to bloating, fatigue, and skin issues. Overexposure, gut health changes, and dietary habits can influence how your body reacts over time.

Sensitivities arise from environmental factors such as dust, pollen, and household chemicals. These triggers can cause respiratory discomfort, skin irritation, and neurological stress. While sensitivities are not the same as allergies, they can still impact daily life by aggravating inflammation and immune response.

Nutrient imbalances occur when the body fails to absorb or adequately utilize essential vitamins and minerals. This can stem from poor diet, food intolerances, or exposure to environmental toxins, leading to symptoms like low energy, brittle nails, and muscle cramps. Addressing these imbalances through personalized nutrition and supplementation can restore optimal function.

Intolerances, sensitivities, and imbalances are deeply interconnected. For example, gut inflammation from food intolerances may hinder nutrient absorption, leading to imbalances. Likewise, environmental sensitivities can stress the body, worsening digestive and metabolic function.

Understanding these connections allows you to take proactive steps toward a healthier, more balanced life.

Enzyme deficiencies and inflammation can cause food intolerances with no signs of immune-mediated responses. Immune responses are often measured with IgG or IgE levels. Therefore, food intolerances or sensitivities are usually not measured using immunogenics. This can be a common misconception in Healthcare that food intolerances are measured through IgE and IgG responses. However, it is known that IgE or IgG responses can measure food allergies. Food allergies and food intolerances or sensitivities can differ significantly.

Diet and lifestyle are known to be responsible for the development of food intolerances and sensitivities. The known recommendation for medical doctors is that patients may test regularly with AFIL's technology, as often as every three months, before symptoms begin reappearing and new food intolerances develop. Testing frequently is the simplest way for patients to take control of their health and help prevent future diseases due to chronic inflammation.
