The bionutritional environments of ACN

Compensating for deficiencies and restoring the proper functioning of our cells by providing them with every essential nutrient in optimum quantities: this is the principle of Active Cellular Nutrition®.

However, it is important to take everyone's needs and characteristics into account relating to specific nutritional inadequacies. Based on ACN, and with reference to thousands of case studies, 7 bionutritional environments have been identified. Each corresponds to a nutritional profile with defined imbalances.

The seven C, H, A, N, B, I, O® environments in detail

The seven C, H, A, N, B, I, O® environments have been defined based on lifestyle, nutrient deficiencies and intoxication, and characteristic functional ailments that underlie deeper disorders.


The C-Environment  is associated with a deficiency in polyunsaturated fatty acids (PUFAs), the 'good' fats that are essential for our body, but which it is unable to synthesis and must therefore source from the diet. They participate in all the functions of the body as they are major constituents of the membranes of all our cells. They play particularly important roles in the communication of the nervous system, hormonal synthesis, skin condition and immunity and inflammation.

The C-Environment is mainly linked with the inadequate intake of essential polyunsaturated fatty acids (high-quality virgin first-press plant oils and oily fish, rich in omega) and with a diet too rich in bad fats (industrially produced foods, animals fats).

• Main indicators of the environment: skin disorders (acne, itching, loss of elasticity), women's troubles, concentration and memory problems, stress, allergies and ENT disorders.


The H-Environment is caused by an imbalance in the processing of carbohydrates (sugars), the fuel for all our cells. After a meal, the sugar consumed circulates in the blood to reach all of the body's cells. When the sugar level in the blood increases the body goes into hyperglycaemia. The high and repeated increase in blood sugar level (by consuming simple sugars) causes excessive release of insulin, a hormone which reduces blood sugar. There is then a significant fall in blood sugar, called reactive hypoglycaemia, a feeling of sudden tiredness.

• The H-Environment is caused by successive bouts of reactive hypoglycaemia due to meals high in sugar content. It is therefore a function of diet, notably snacking on sugary foods between meals (biscuits, fizzy drinks, sweets…), an excess of simple sugars (pastries, industrially produced foods) and meals low in fibre and complex sugars, which take longer to enter the bloodstream and therefore have a lesser effect on the blood sugar level.

Main indicators of the environment: general fatigue, sudden tiredness, dizziness, hunger, frequent sugar cravings, headaches, trembling, stress, nervousness, disrupted sleep, metabolic disorders (diabetes) and excess weight.


The A-Environment is linked to the body's problems neutralising the excess acid provided via the diet and/or by metabolism. Acid formation regularly occurs in the body. Yet for optimum functioning, our tissues must maintain a constant pH. To rebalance tissue acidity, the body uses an acid neutralisation system exploiting alkaline minerals. Excess acid can lead to the basic minerals becoming exhausted, and therefore to the general demineralisation of the body.

The A-Environment is caused by excessive consumption of acidifying foods (meat, sugars, cheese…) and by factors that promote tissue acidification such as stress, intense physical activity and inadequate elimination (urine, sweat…).

Main indicators of the environment: cramp, osteoarticular discomfort, fragile bones, inflammation, fatigue, low resistance to stress, hypertension and low immunity.


The N-Environment results from emotional disorders caused by repeated stressful situations. Such aggressions can lead to chronic stress able to deregulate the body, notably the synthesis of neurotransmitters, our body's messengers that regulate our moods and reactions. If the level of neurotransmitters is disrupted, sensitivity to aggression increases and stress coping mechanisms are undermined, leading to various disorders.

The N-Environment is caused by repeated exposure to stressful situations (injury, illness, family and work problems…) associated with dietary and physiological factors: inadequate intake of the amino acids required to produce neurotransmitters, poor assimilation or degradation of the amino acids, poor neuronal communication due to a deficiency in the polyunsaturated fatty acids that constitute the cell membranes, poor neurotransmitter reception.

Main indicators of the environment: disturbed sleep, fatigue, depression, nervousness and anxiety, hyperactivity, palpitations, digestive disorders.


The B-Environment is due to an imbalance in the intestinal ecosystem, composed of the intestinal mucosa, the microbiota (or intestinal flora) and the immune system associated with the intestine. This trio is in constant interaction and plays a fundamental role in the digestion, the barrier function of the intestine and the immune defences of the body. The microbiota is without doubt the main element of this ecosystem. Composed of 'good' bacteria, it protects us by combating the proliferation of pathogens, by activating the immune system and maintaining intestinal integrity and effective absorption of nutrients in the diet.

The B-Environment is caused by bad dietary habits and environmental factors that disrupt the intestinal microbiota: lack of fibre, excessive sugar consumption, stress, lack of physical activity and the taking of antibiotics.

Main indicators of the environment: digestive disorders, intestinal pain, gas and bloating, weakened immune defences, allergies, ENT ailments and inflammation.


The I-Environment corresponds to an accumulation of toxic substances in the body and/or deficiencies in the systems that promote elimination. Every day we are exposed to toxins: tobacco, pesticides, food additives, pollution, medicines, heavy metals… Fortunately our body possesses detoxification mechanisms that mainly take place in the liver, intestine and kidneys. Enzymes transform undesirable substances into derivatives that are eliminated in the stools and urine. However, when these 'depollution' mechanisms become saturated, toxic substances accumulate, leading to various disorders.

The I-Environment is caused by the assimilation of toxins via the diet (additives such as colourings and preservatives, pesticides, hormones and antibiotics in intensively reared meat and fish, metal and plastic utensil coverings) and the environment (air, water and soil pollution, chemicals).

• Main indicators of the environment: neurological disorders (nervous fatigue, difficulty concentrating), disorders related to hormonal imbalance (women's problems, disrupted libido and fertility, early-onset puberty) and disorders related to hepatic overload (poor digestion, nausea, pale skin).


The O-Environment is related to excessive free radicals in the body. Free radicals are created in the cells during the natural energy production process that uses oxygen. They are unstable molecules that react by attacking different molecules to try and restore balance. Such attacks cause significant damage, notably to the DNA (gene modification), the proteins (degraded functions) and the cell membranes (disrupted cellular permeability and integrity). Free radicals can be neutralised by antioxidative molecules and mechanisms.

The O-Environment is above all associated with environmental factors that trigger excessive production of free radicals: irradiation, pollution, tobacco smoke and heavy metals. This environment can also be explained by weak antioxidative defences, notably via a diet low in plant-sourced antioxidants.

Main indicators of the environment: accelerated ageing, notably of the skin (lines, marks, loss of elasticity), cardio-vascular problems, chronic inflammatory processes (osteoarthritis, AMD) and neuro-degenerative disorders.

IoMET® – The environment analysis tool

IoMET® was developed to analyse and provide a simple an quick visualisation of the imbalances and disruptions of the different environments.

It is used to identify each person's dominant environment and the source of the observed disorders, as well as to offer individualised intake advice via a suitable diet.
