Food Sensitivity

  • Food sensitivity is not an allergy but an intolerance or inflammatory reaction
  • The histamine bucket: total load determines symptoms, not the last bite
  • A1/A2 difference: not all dairy is the same
  • Systematic self-research provides insight
  • Your body communicates through symptoms

Many people experience vague physical symptoms after eating, but don’t know exactly why:

  • Runny nose after cheese
  • Bloated feeling after wine
  • Itchy skin
  • Fatigue after the meal

Histamine is a natural substance present in everyone’s body, but in some people it can accumulate too much.

CategoryExamples
FermentedAged cheese, wine, sauerkraut
Smoked/preservedSmoked meat, canned fish
OtherAlcohol, stress
  • Runny or stuffy nose after the meal
  • Flushing or itching
  • Headache
  • Cold hands or feet
  • Fatigue after eating

Not all milk is the same.

TypeSourceEffect
A1 beta-caseinModern dairy cowsCan form BCM-7 (opioid-like, pro-inflammatory)
A2 beta-caseinGoats, sheep, older cattle breedsDoes not form BCM-7

Some people tolerate goat cheese or sheep yogurt well, but get symptoms from regular cow’s milk.


Food can trigger autoimmune reactions in sensitive people. The immune system then considers certain nutrients as “enemy.”

  • Hair loss
  • Skin rash
  • Stiffness
  • Fatigue
  • Mood swings
  • Concentration problems

Self-research — your ‘forensic food investigation’

Section titled “Self-research — your ‘forensic food investigation’”

Record for at least two weeks:

What to noteDetails
Time and type of foodFresh or processed
Time of symptomsHow long after eating
IntensityScore 1-10
Additional factorsStress, sleep
PhaseApproach
EliminationRemove one food group for 3-4 weeks
ReintroductionAdd one product at a time
IntervalAt least 3 days between each reintroduction

When you have suspicions, you can perform deliberate provocations:

TestMethod
Histamine testDay with lots of histamine-rich food (aged cheese, wine, sausage) and observe
A1/A2 testTest A1 and A2 dairy separately
Time patternFast symptoms = histamine/allergy; delayed symptoms = inflammation

Those who learn to listen can act purposefully:

  • Calmer eating
  • Simpler meals
  • Less processed food
  • Better matched combinations


Veelgestelde vragen

What is food sensitivity?

Food sensitivity is not an allergy, but an individual intolerance or inflammatory reaction to certain foods. Important mechanisms are histamine load, protein mimicry (A1/A2 difference), and autoimmune reactions.

What is the histamine bucket?

Histamine can accumulate too much in some people. Foods like aged cheese, wine, fermented products, and stress increase the load. When the 'bucket' overflows, symptoms like runny nose, itching, headache, or fatigue arise.

What is the A1/A2 difference with dairy?

Modern dairy cows produce A1 beta-casein which can be pro-inflammatory. Goats, sheep, and older cattle breeds produce A2 casein without this effect. Some people tolerate goat cheese well but not cow's milk.

How do I do an elimination-reintroduction?

Note for 2 weeks what you eat and which symptoms arise. Then remove one food group for 3-4 weeks. Afterward, add one product at a time with at least 3 days between each reintroduction to identify reactions.
