A recent study by Brie M. Reid, a developmental psychobiologist at Northeastern University, suggests a powerful link between early life stress and dietary preferences, potentially influencing long-term health outcomes. The research, conducted at the REID Lab, found that individuals who experienced early institutionalization or other forms of early adversity were more likely to gravitate towards highly inflammatory diets in adolescence and young adulthood.

Why it matters

The implications of this research extend far beyond the study participants, as an estimated 152 million children worldwide are orphaned and may experience early life stress and potential neglect. Understanding the long-term consequences of these experiences is crucial for developing effective support systems and interventions to help mitigate the impact on dietary choices and overall health.

The details

The study involved 190 participants aged 12-21, comparing those who experienced early institutionalization with a control group raised in stable family environments. The findings revealed that individuals with a history of early life stress were more likely to choose inflammatory foods, as confirmed by higher levels of inflammation markers in their blood tests. Researchers suggest that early stress can alter brain development, potentially impacting impulse control and leading to a preference for inflammatory foods as individuals gain more autonomy over their dietary choices.

  • The study was conducted by Brie M. Reid and the REID Lab at Northeastern University's Bouvé College of Health Sciences.
  • The UNICEF report estimating 152 million orphaned children worldwide was published in July 2025.
