According to the text, the most likely causes of precocious puberty are exposure to pollutants
, exposure to phthalates and unhealthy weight gain.
Explanation:
The age of onset of puberty has experienced significant variations over the years, mostly related to environmental changes and use of processed products.
Factors associated with precocious puberty are:
Industrialization produced an increase in environmental pollutants, which has been linked to early puberty.
Consumption of processed foods —which favour obesity— influences the production of hormones, that can induce early sexual maturation.
Finally, some chemical additives, such as phthalates, enter the body and resemble the structure of some hormones, inducing a hormonal behavior that promotes alterations, such as an early onset of puberty.
The text also mentions negative consequences for the body when an early onset of puberty occurs.
