The Claim
Digital health tools are associated with modest improvements in dietary quality during pregnancy, including increased vegetable intake and reduced dietary risk scores, among overweight or obese women, with effect sizes ranging from β = 0.55 to 0.82.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Among overweight or obese pregnant women, the use of digital health tools is linked to slightly higher vegetable consumption and lower dietary risk scores.
See the scientific wording
Digital health tools are associated with modest improvements in dietary quality during pregnancy, particularly increased vegetable intake and reduced dietary risk scores, with effect sizes ranging from β = 0.55 to 0.82 in studies involving overweight or obese women, suggesting these tools may support healthier eating patterns in a high-risk population.
When pregnant women use digital tools to track their food intake, the tools send reminders and visual feedback about eating patterns. This repeated exposure helps the brain link specific cues — like time of day or emotional state — with healthier food choices. Over time, the brain strengthens neural pathways that make choosing vegetables and avoiding high-risk foods feel automatic, reducing the need for conscious effort.
What the research says
1 studyDigital apps and text reminders helped pregnant women who were overweight or obese eat more vegetables and make healthier food choices, according to a big review of studies. The improvements were small but real and consistent.
