Top 8 Food Intolerance Tests 2023

Food intolerance tests have become increasingly popular due to a variety of stressors that can negatively impact our digestive systems. Medications, preservatives, artificial ingredients, and stress are just a few factors that can disrupt the balance of digestive enzymes in our bodies, causing a range of discomfort symptoms including headaches, acne, inflammation, bloating, weight gain, acid reflux, and even arthritis.

As people are becoming more aware of these potential triggers and the impact they can have on health, they are turning to food intolerance tests as a way to identify problem foods and manage their diets more effectively. By eliminating or reducing foods that are causing negative symptoms, both people and pets can improve their overall health and quality of life. 

Best Adult & Kids Food Intolerance Tests

Food intolerances, also known as food sensitivities, refer to an adverse reaction to certain foods or ingredients in food that does not involve the immune system. Unlike food allergies, which involve the immune system and can have immediate, life-threatening effects, food intolerances occur over a longer period of time, and are caused when the body has difficulty processing certain foods or the components of food, such as lactose or gluten.
