Professor Alan Boobis OBE, Toxicologist, Division of Medicine, Imperial College London states that "The body’s own detoxification systems are remarkably sophisticated and versatile. They have to be, as the natural environment that we evolved in is hostile. It is remarkable that people are prepared to risk seriously disrupting these systems with unproven ‘detox’ diets, which could well do more harm than good."[11]
« Que ce soit par transmission alimentaire (maladie de la vache folle, salmonelloses), par transmission vectorielle (fièvre du Nil occidental, fièvre de la vallée du Rift, encéphalites à tiques), ou encore par simple contact (rage), les possibilités de transmission interspécifique sont multiples et demandent une approche collaborative entre les secteurs de la santé animale et de la santé humaine pour prévenir et contrôler ces infections »4.
The premise of body cleansing is based on the Ancient Egyptian and Greek idea of autointoxication, in which foods consumed or in the humoral theory of health that the four humours themselves can putrefy and produce toxins that harm the body. Biochemistry and microbiology appeared to support the theory in the 19th century, but by the early twentieth century, detoxification based approaches quickly fell out of favour.[6][7] Despite abandonment by mainstream medicine, the idea has persisted in the popular imagination and amongst alternative medicine practitioners.[8][9][10] In recent years, notions of body cleansing have undergone something of a resurgence, along with many other alternative medical approaches. Nonetheless, mainstream medicine continues to view the field as unscientific and anachronistic.[9]

The two previous health programmes from 2008-2013, and 2003-2007 generated knowledge and evidence that served as a basis for informed policymaking and further research.This included best practice, tools, and methodologies that secured benefits for both the public-health communities and citizens directly (e.g improving diagnostic tests, supporting EU countries in developing national actions plans on cancer, improving patient care).
As a way of life, it is good to reduce the toxin load by eliminate alcohol, coffee, cigarettes, refined sugars and saturated fats. This would of course be the case especially whilst doing a detoxing program.  Also, clean up your household cleaners and personal health care products, by selecting more natural alternatives, rather than the chemical based products.
Visit your doctor if you have any health concerns. If you have any issues that are making you feel like you need to do a detox, then you might have an underlying health issue. If this is the case, it’s much better to handle that health issue with professional medical help. Don’t hesitate to visit your doctor for an exam if you think something might be wrong. This is the best choice to protect your health.[12]
