Experts are urging pregnant women to reduce their sugar consumption, citing a study that indicates a potential link between high sugar intake during pregnancy and an increased risk of mental health issues in children later in life.

The study, published in the journal General Psychiatry, found that individuals born during post-war rationing, when sugar was restricted, experienced up to a 25% lower risk of developing anxiety and depression in adulthood compared to those born after sugar restrictions were lifted in 1953.

Researchers emphasized that the first 1,000 days after conception are crucial for mental health development. They suggest that future public health guidelines and policies should incorporate recommendations to lower sugar intake for expectant mothers and young children.

"Sugar restriction in the first 1,000 days after conception plays a crucial role in mental health later in life," the study stated.

Dietitian Sarah Schenker, author of "My Sugar Free Baby And Me," supported the call for updated guidelines. "What this research shows quite powerfully is that sugar is not just bad for your teeth and waistline, but it can damage mental health too," Schenker said.

Current National Health Service guidelines for the UK recommend that babies aged one year can consume up to 10 grams of sugar per day, equivalent to about two and a half sugar cubes. The study highlights that sugar consumption rose significantly after restrictions ended in the post-war era.

This research adds to a growing body of evidence exploring the impact of maternal diet on fetal brain development and long-term child health outcomes.
