Limiting sugar intake during pregnancy may protect children from developing anxiety and depression later in life, according to a study published in the journal General Psychiatry. Researchers found that individuals born during periods of post-war sugar rationing, when consumption was restricted, exhibited a significantly lower risk of mental health diagnoses in adulthood.

The study suggests that sugar restriction in the first 1,000 days after conception plays a crucial role in long-term mental well-being. The findings indicate that those conceived before sugar restrictions were lifted in 1953 had up to a 25% lower risk of developing these conditions.

Health experts have called for the National Health Service (NHS) to implement stricter recommendations for expectant mothers regarding sugar consumption. "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," said dietitian Sarah Schenker, author of My Sugar Free Baby And Me, who supports the call for new guidelines.

This research adds to a growing body of evidence suggesting a connection between maternal sugar consumption and a child's brain development. Current NHS guidelines advise that babies aged one can consume up to 10 grams of sugar per day, equivalent to two and a half sugar cubes. Experts suggest that future public health guidelines should consider reducing recommended intake for pregnant women and young children.
