“…The aim of the present study is to consider the functions of the psychological and normative silences [ 17 ] presented by pregnant and breastfeeding women living in two regions of Spain regarding their perceptions of environmental risks and food safety [ 18 , 19 , 20 , 21 , 22 ]. There is growing evidence that continued exposure to low doses of pollutants, as occurs in most of the general population, could increase the risk of developing various chronic pathologies, such as cancer, cardiovascular disease or diabetes [ 20 , 23 , 24 , 25 ], and also that exposure to various persistent toxic compounds (Polychlorinated Biphenyls, DDT, Heptachlor, Hexachlorobenzene, Dioxins…) during pregnancy has been associated with alterations in foetal growth, new-born weight, asthma, risk of pre-term birth or alterations in neurodevelopment, among others. Persistent toxic compounds are chemicals used in agricultural and industrial production that accumulate in the body in small doses, mainly through the consumption of foods containing animal fats, and carry a silent risk due to the short-term invisibility of their consequences, as well as a diffuse and multifactorial causation of diseases and disorders resulting from this type of toxicity [ 26 , 27 ].…”
