Researchers from the Wroc\u0142aw-based research institute have uncovered biological links between women\u2019s adverse childhood experiences and the composition of their breast milk after childbirth.<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The findings, just published in Translational Psychiatry<\/em>\u2014one of the world\u2019s leading journals in neurobiology\u2014may transform our understanding of how early-life experiences in women influence infant behavioral development and the health of future generations.<\/p>

The study was led by Dr. Ali Jawaid<\/strong>, physician and neuroscientist specializing in transgenerational trauma research, who since 2024 has served as the leader of the Translational Neuropsychiatry Research Group<\/strong><\/a> at \u0141ukasiewicz \u2013 PORT. The project was conducted in collaboration with Prof. Anna Ziomkiewicz-Wichary<\/strong> of Jagiellonian University in Krak\u00f3w.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Researchers examined 103 mothers and their infants, analyzing breast milk composition\u2014specifically epigenetic regulators and fatty acids\u2014and comparing women with different levels of adverse childhood experiences (ACE).<\/p>

The results clearly show that the milk of mothers who experienced more traumatic events in childhood contained:<\/p>

  • Higher levels of specific microRNAs<\/strong>, which may influence the development of the infant\u2019s immune, nervous, and metabolic systems.<\/li>
  • Lower concentrations of medium-chain fatty acids<\/strong>, which reduce the nutritional value of the milk.<\/li><\/ul>

    Moreover, these alterations correlated with temperament characteristics observed in infants at 5 and 12 months<\/strong> of age and remained significant even after accounting for maternal postpartum depression symptoms.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    \u201cOur findings show that human milk is not only a source of nutrients but also a complex carrier of epigenetic signals shaped by mothers\u2019 life experiences\u2014even those from childhood,\u201d<\/em> says Weronika Tomaszewska<\/strong> of \u0141ukasiewicz \u2013 PORT, the paper\u2019s first author, who worked on the project for several years.<\/p>

    Her supervisor, Dr. Ali Jawaid<\/strong>, adds:
    \u201cMicroRNAs in breast milk may serve as biomarkers of lived experiences in humans and could predict the transmission of behaviors across generations. It is fascinating to discover that the way we live can not only affect ourselves and our loved ones but also alter the biology of future generations.\u201d<\/em><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
