Nutrition with HPU

What do you eat with HPU?

Most HPU patients (about 80% according to Dr. Tina Maria Ritter) benefit from a diet without:

  • wheat (spelt or gluten-free instead)
  • cow’s milk products (instead goat and sheep’s milk products)
  • soya (almond or rice milk instead)
  • eggs
  • yeasteizen (stattdessen Dinkel oder glutenfrei)

The food should preferably come from organic farming (low in toxins and pesticides, rich in nutrients) and be freshly prepared (low in histamine). Due to the intestinal damaging effect of many additives, HPU users should generally avoid ready-made meals of any kind. A low-carbohydrate diet adapted to individual intolerances has proven to be positive. Alcohol and caffeine are poorly tolerated by many HPU users.

Reduce carbohydrates

HPU users often have problems with blood sugar levels. Kamsteeg describes that 78% reported that they experience cravings between meals in questionnaires from the Keac research institute. 70 % of HPUs reported nausea, trembling and dizziness when hungry.

The reasons for this are the poor utilization of fructose (due to zinc deficiency) and problems with the activation and deactivation of insulin (due to vitamin B6 deficiency) in HPUs.

The body needs gluthation to activate and deactivate insulin in the liver. Gluthation consists of the three amino acids glutamic acid, cysteine and glycine. To build cysteine, the body needs two molecules of pyridoxal 5-phosphate (P5P, the active form of vitamin B6).

Avoid toxins in food

Basically, HPUs are bad detoxifiers. Therefore, the food an HPU sufferer consumes should be as little contaminated with pesticides and other toxic substances as possible.

These foods should be organic:

Some plants are treated with pesticides or other pesticides more often than others. Then there are plants that prefer to absorb and store toxic substances from the soil. If you want to absorb as few toxins as possible through your food, you should buy these foods in organic quality or produce them yourself.

The Environmental Working Group (EWG) from the USA annually compiles its list of “Dirty Dozen” (the dirty dozen). In it they list the foods that are most heavily contaminated with pesticide residues. There is also a positive list of foods where few pesticides have been found.

Organically produced food is generally more expensive than conventionally produced food. If you cannot/do not want to buy all food in organic quality for cost reasons, you should prefer the organically produced variant for the following products, as conventionally produced foods of this type are more frequently contaminated with pesticides or other toxic substances than others:


Organic is not the same as organic. Foods that only comply with the EC Organic Regulation must meet the lowest requirements for certification.

Products that carry a label of an organic farming association (Bioland, Demeter, Naturland, Bio-Suisse, Bio Austria etc.) are subject to stricter requirements. You can read about the requirements behind the labels here.


green beans




Milk products
meat and fish

(can also contain a lot of arsenic in organic quality, therefore wash very thoroughly with hot water before preparation)

Meat from grazing livestock

Meat from organically fed cattle from pasture farming not only contains fewer toxins, but also a more favourable omega-3/6 ratio than meat from animals from conventional farming. The omega 3/6 ratio is particularly important in the regulation of inflammatory reactions in the body, which can often occur with a Leaky Gut.


Meat and fish are important sources of zinc. Vegetarians should pay particular attention to the consumption of food containing zinc. Lentils, peas, carrots, wheat bran, nuts, corn, eggs and berries contain a lot of zinc.

Is there an HPU diet?

No, because the HPL complex excretes so much vitamin B6 and zinc that these deficiencies cannot be compensated for by diet alone.

However, the diet can support the HPU micronutrient therapy.

Micronutrients in food

HPU users have a higher micronutrient requirement than people without HPU. However, our food contains fewer micronutrients than that of several decades. This is mainly due to the depleted soil on which our food is produced.

It is not possible for the HPUler to cover the demand for micronutrients through food alone. Nevertheless, at least a large part of the required micronutrients should come from high-quality food.

Grain / Gluten

Many people with HPU are sensitive to cereals containing gluten. These intolerances can manifest themselves as flatulence, irregular stool, abdominal pain, nausea, but also headaches and aching limbs. Both Dr. Kamsteeg and other therapists (Dr. Joachim Strienz, Kyra and Sascha Kaufmann, Dr. Tina Ritter) report a frequently observed cereal intolerance that has been proven by IgG tests. Dr. Strienz cites manganese deficiency as one possible reason for this. Under micronutrient therapy this intolerance can improve and the gluten deficiency can be loosened.

Dr. Strienz only recommends gluten reduction to his patients (not all meals should contain gluten-containing foods). In Kyra and Sascha Kaufmann’s case, the LOGI® method developed by nutritionist Dr. Nicolai Worms has proven its worth. It is based on significantly fewer cereal products, but more vegetables, healthy fats and more proteins than the German Nutrition Society (DGE) currently recommends.

Eggs / dairy products

Besides gluten, eggs and dairy products often cause intolerances. Many HPU patients with gastrointestinal complaints experience improvement if they avoid cereal and dairy products as well as eggs.

Dairy products from sheep and goats are usually better tolerated by HPU users than cow’s milk products.


A common side effect of HPU is fructose malabsorption (fructose intolerance). It is based on a disturbed transport system for fructose in the small intestine. More about fructose intolerance can be found here.

Those affected should reduce their fructose intake to a minimum. Fructose is difficult to metabolize, especially from fruit juices and soft drinks, because it is absorbed quickly, in large quantities and without accompanying substances such as polyphenols or dietary fibres.


Even if no histapenia or histaminosis has been detected, HPUlers should consume histamine-containing foods and beverages only in moderation. The reason for this is that the body needs a lot of zinc and vitamin B6 for the histamine breakdown in the intestine. Further information about histamine intolerance and an appropriate diet can be found here.


HPU people with thyroid problems should consume soy in moderation. The reason for this is that soy is rich in isoflavonoids. Isoflavenes can prevent the thyroid hormone T4 from binding to certain proteins. As a result, more T4 is excreted. Isoflavenes also hinder the conversion of T4 into T3 by inhibiting 5`-dejodinase.
