Suggestions for the prevention of chronic diseases

How to reduce exposure to epithelial barrier-damaging agents in homes:

  • Choose sodium lauryl sulphate free and fragrance-free and natural household cleaning products:
  • Avoid detergents, surfactants, and disinfectants that can compromise epithelial barrier integrity.
  • Look for cleaning products made with natural, gentle ingredients.
  • Vinegar is commonly used in many households and no unwanted or side effects have been reported.
  • Stay away from sodium lauryl sulphate containing products.
  • It is possible to dilute the cleaners much more than suggested, you can still get a good cleaning effect.
  • Limit the use of air fresheners and chemically scented products:
  • Many air fresheners, candles, and personal care products contain chemicals that can damage epithelial cells and microbiome.
  • Be aware that fragrances used in cleaning products are not natural substances. They are chemicals that have a similar smell. Use unscented or naturally-derived alternatives.
  • Consider using an air purifier, especially in high-traffic areas.


Approximately ten billion ton plastic has been produced in the world and a huge amount has entered to our lives as plastic pollution and waiting to be degrated in the nature. Microplastics have been shown in amniotic fluid, pericardial fluid and coronary artery plaques. It is damaging epithelial barriers, binding to hormon and other receptors, physically affecting cells and tissues, changing cell and tissue metabolism.
