Do you have digestive problems ?

Stomach pain, bloating, gas, diarrhoea, constipation...

Digestive problems ?

Rheumatism ?

Chronic fatigue ?

You might have food intolerance!

« People are not equal in terms of what they can eat.
Today, a food can procure health or constitute a poison »

A food intolerance has negative effects on the body. These effects are insidious and progress slowly and can generate a whole range of different health problems, such as:

  • Digestive problems (gas, bloating, pain, constipation, diarrhoea)
  • Concentration and memory loss disorders
  • Insomnia, night terrors
  • Haemorrhoids
  • Allergies, asthma, hay fever
  • Chronic fatigue, burnout/professional exhaustion
  • Obesity, cellulitis
  • Diabetes
  • Rheumatism (arthritis, arthrosis)
  • Fibromyalgia
  • Anxiety, depression

  • Hyperactivity, irritability
  • Cardiovascular diseases
  • Skin diseases (psoriasis, erythema, acne…)
  • Coeliac disease, irritable bowel syndrome
  • Auto-immune and degenerative diseases
  • Behavior disorder (irritability, hyperactivity, anxiety, depression, autism, schizophrenia …)

… and many other affections and diseases.

“modern lifestyle” diseases are rapidly increasing


Today, there are more than 67 million people suffering from autism (ASD) in the world. In less than 50 years, the number of autism cases in France has multiplied by 17.

Alzheimer’s disease

The number of Alzheimer’s cases has exploded.


Type 2 diabetes is another disease that has increased dramatically. In 1985, 30 million people were diagnosed and in 2010, 285 million (according to WHO).

Why ?


Many research laboratories speak about genetical weaknesses, but genetics cannot reply to a practically epidemical rise in certain diseases. Moreover, not many people are aware of that toxics accumulate from generation to generation as the future mother transmit them to the fetus.

Toxic substances
(heavy metals, toxic chemicals, nanoparticles…)

Increasing exposure

We should take other factors into account, such as the numerous toxic substances to which humans are exposed via:

  • the air and the water
  • the food (pesticides, fertilisers, chemical food additives, processed foods, cooking methods, food packaging)
  • vaccinations, tooth fillings an drugs
  • makeup and cosmetics
  • certain cloths
  • cleaning products
  • electro-magnetique pollution
  • by coatings and furniture at home/at work /in the car, etc.

Moreover, the human body accumulates heavy metals and chemicals from generation to generation by placental transfer from mother to foetus.


A need to protect yourself

Industry uses today thousands of chemicals that have not been tested for their effect on human health and the environment. Engineered nanoparticles are put into our food but, again, no regulations have been established or tests by regulatory bodies, either in EU or in the US. Heavy metals and other toxic chemicals affect negatively the health of more and more people today. The world’s experts in toxicology admit that they do not know the extent of the damage caused by the cocktail of these toxic substances in the human body.

We are ALL exposed to toxic substances today. The body absorbs toxic substances daily. Individuals who remain healthy excrete them, sick individuals do not have this ability. The intestine plays a key role to heal. A healthy intestine provides 70-75 % of the immunity of a person.


I offer the following services:

Health assessments

Health assessments and laboratory testing to identify the underlying root causes of your visible health problems. Please find below a list of the most frequently used analyses

  • Food intolerance testing (searching for delayed hypersensitivity, which not the same as searching for coeliac disease via the transglutaminase protein)
  • Heavy metal poisoning analysis (porphyrins)
  • Analysis to determine the balance of intestinal flora
  • Analysis of opioid peptides (searching for brain neurotransmitter receptor poisoning caused by gluten and casein/milk protein)
  • Vitamin and mineral status analysis
  • Immediate hypersensitivity/allergy (metals, foods, etc.)
  • Fatty acid profile of the erythrocyte membranes
  • Analysis of oxidative stress of the cells (DNA, RNA, cell membranes)
  • Cellular mediation analysis of the inflammatory status of the body



Coaching and support including practical tips.

Dear Helena,

All our wishes of happiness and health for you and your family!
L. (my daughter) is doing very well. She has finally had a quiet and healthy winter. We are so happy for her and so is she.

Talk to you soon!
Best regards,

Nicole, 2017 (Geneva)

Dear Mrs Sundström, thank you for your email and I send you all my best wishes for this new year.

As for my health, I think I am on the right track: the bio-identical medicine (gluten-free, lactose-free) I take for my thyroid suits me well and the daily dosage is distributed in several doses over the day. The gluten-free diet etc. has become quite simple, even when I go to a restaurant. My digestive problems have considerably diminished. They even completely disappeared during the week I spent on an island in the Caribbean!!!

I would like to point out that you have found the solution to my suffering (digestive problems and unexplained weight gain) that lasted countless years while I consulted a myriad of doctors and specialists without success. Since last year, I have lost approximately 13-15 pounds without doing sports or exercises, just by eliminating the food to which I am intolerant and by changing my thyroid hormone medicine to a bio-identical one (which is not reimbursed by the health insurance because it’s an American product!).

Thank you and have very good day,

Best regards,

Nicole X.

I have now benefitted from personalized Stelior coaching from Helena for about 6 months, and I appreciate:

  • The innovative approach and “deciphering” of the analyses: this is the first time I have been provided with such precise information on my health based on “quantitative” analyses.
  • The pedagogy used for decrypting the biological data: the information was clear, and well explained.
  • The step-by-step management of the information in terms of analysing the results and the change in diet: Very satisfying handling of the patient’s individual capacity to absorb and to adapt!
  • The tips provided to facilitate the diet change: special products available on the market, recommended substitutes, herbal teas, oils to use, etc.
  • The regular telephone contact was pertinent. The encouragements were very helpful. Quick response to the questions I sent by mail or SMS. Always concerned about explaining the « reasons » behind why we did this or that.
  • les encouragements étaient très utiles

What could be done better?

  • The intestinal cleansing: create a synthetic Excel table grid that defines which complements to take and when rather than an email with text
  • The recipes: an update (without millet for example) and a more homogeneous and structured layout would be appreciated … but I understand that this might take time for Stelior to do…
  • Sheets could be proposed concerning the larger food principles: which oils to be heated or not, which fats to use, etc. I believe this is basic information that could be delivered to everyone.

To sum up, many thanks to Stelior and Helena for quality coaching, which resulted in acquired knowledge, which I wish to perpetuate.

Fabienne, feb 2015 (Geneva)

Hello and thank you, this is perfect!
I adapt very well to a gluten-free living … thanks to your recipes, I have identified ways to substitute the usual food I eat and it ends up being less complicated than I had imagined at first. In any case, I already see clear digestive improvements and the heaviness I used to feel is almost gone!
I look forward to continuing the counselling once we have received all the results.
