Many people experience abdominal pain, bloating, or fatigue after eating. This is often dismissed as "sensitive intestines" or stress, but in reality, it may be a food intolerance. My InnerSelfie combines DNA, metabolite, and microbiome test results to identify the real cause—and restore your digestion.

Intolerance ≠ allergy

An allergy is a direct immune response, often life-threatening. An intolerance is more subtle: your body lacks the enzymes or bacteria needed to properly process a nutrient.

• Lactose intolerance: genetic variants determine whether you produce lactase. People who do not produce this enzyme have difficulty digesting milk. A lactose intolerance test via DNA analysis can reveal this. However, the story does not end there: your microbiome can partially compensate for this. Bacteria such as Bifidobacterium and Lactobacillus break down lactose and can alleviate symptoms. This shows why a DNA test alone can never tell the whole story.
• Fructose intolerance: a deficiency in enzymes or transporters can lead to abdominal discomfort.
• Histamine intolerance: an imbalance in enzymes and the microbiome can cause hypersensitivity.

According to The Lancet Gastroenterology & Hepatology (2022) ,food intolerances are one of the most underestimated causes of chronic intestinal complaints, oftenconfused with IBS (irritable bowel syndrome). 

The role of DNA and microbiome

1. 
   food intolerance DNA test A nutrigenetics (or nutrigenomics) test shows whether your genes produce enzymes well or poorly. This reveals whether you have a predisposition to lactose, gluten, or histamine intolerance. A gluten allergy test using DNA analysis can reveal sensitivity to celiac disease.
2. 
   microbiome analysis Your microbiome can either exacerbate intolerances or buffer them. In the case of lactose intolerance, for example, beneficial bacteria take over part of the digestion process, while an impoverished microbiome can actually worsen these symptoms.
3. Metabolites
   By measuring metabolites, you can see what is really happening in your digestive system - and whether there are deficiencies or accumulations causing symptoms.

Solving digestive problems with multi-omics

Springer Nutrition Reviews (2022) states that only multi-omics (DNA + microbiome + metabolites) can provide a complete picture of digestive problems.
With My InnerSelfie, you not only discover what is going wrong, but also why:

• Is it genetic?

• Is it because of your gut flora?

• Or by a combination of both?

Practical applications

1. How can I get rid of my intestinal problems?
   By identifying the cause through a comprehensive multi-omics test, you will receive personalized advice on nutrition, lifestyle, and whether or not to take supplements.
2. Solve intestinal problems
   Pre- and probiotic strategies help restore your microbiome and buffer intolerances.
3. Digestive problems reduce
   Small adjustments in meal structure (e.g., timing of carbohydrates or histamine-rich foods) often have a big effect.

Helicopter view of My InnerSelfie

Instead of single elimination diets, My InnerSelfie offers a holistic plan with our advanced DNA test for food intolerance:

• DNA → predisposition to intolerances.
• Microbiome → buffer or enhancer.
• Metabolites → current status.

So you finally know where your symptoms are coming from - and how to address them permanently.

Key insights

• Intolerance ≠ allergy: often subtle enzyme or microbiome problems.
• DNA and microbiome together determine how you process food.
• Even without lactase (DNA), your microbiome can partially digest lactose.
• Multi-omics is the key to solving digestive problems.
• My InnerSelfie offers a holistic approach that goes beyond symptom relief.
