New research shows obese toddlers are at risk for being iron deficient.
The study, in this month's issue of the Journal Pediatrics, is the first to discover a link between obesity and low iron levels in preschoolers.
Iron deficiency can cause mental and behavioral delays. The findings talk about the importance of healthy eating habits in children ages 1 to 3.
The researchers found that 20% of obese toddlers have an iron deficiency, compared to 7% of toddlers who have a normal weight.
Experts say mothers are to blame by feeding toddlers cow's milk and juice which are low in iron, instead of feeding them iron-rich substances.
