Children not eating vegetables may receive less fibre and fewer vitamins, minerals, and protective plant compounds, although the actual effects depend on their overall diet. This guide explains seven possible consequences, including constipation, nutrient gaps, reduced dietary variety, and difficulty maintaining balanced eating habits. It also explores why children refuse vegetables, whether fruit or supplements can replace them, and how much they may need at different ages. Parents will find gentle, pressure-free strategies for increasing familiarity with vegetables, along with warning signs such as poor growth, swallowing difficulties, extreme restriction, or severe distress that require professional support.
