Iron deficiency can be caused by several factors, including:
- Inadequate dietary intake: Not consuming enough iron-rich foods, especially in populations with higher iron needs (e.g., pregnant women, children).
- Increased needs: Growth spurts in children, pregnancy, and breastfeeding can increase iron requirements.
- Blood loss: This can occur from heavy menstrual periods, gastrointestinal bleeding (e.g., ulcers, hemorrhoids), or injuries.
- Malabsorption: Conditions like celiac disease, Crohn’s disease, or gastric bypass surgery can hinder iron absorption in the intestines.
- Chronic diseases: Some chronic conditions can lead to reduced iron availability or utilization.
Iron deficiency in infants can lead to developmental delays and health issues. Common causes include:
- Insufficient iron intake: Exclusively breastfeeding infants may not get enough iron after six months unless complementary iron-rich foods are introduced.
- Premature birth: Premature infants have lower iron stores and higher needs.
- Rapid growth: Infants experience significant growth, increasing their iron requirements.
- Low iron in maternal diet: If the mother had low iron during pregnancy, the infant might be born with low iron stores.
Signs of iron deficiency in infants can include irritability, poor feeding, fatigue, and delayed milestones. Screening and appropriate dietary adjustments are crucial for prevention and treatment.
Iron-rich foods include:
- Red meat: Beef, lamb
- Poultry: Chicken and turkey.
- Fish and seafood: Tuna, salmon, and shellfish like oysters and clams.
- Legumes: Lentils, beans, and chickpeas.
- Nuts and seeds: Pumpkin seeds, almonds, and cashews.
- Dark leafy greens: Spinach & kale
- Fortified foods: Some cereals and bread are fortified with iron.
- Tofu and tempeh: Good sources for vegetarians and vegans.
Pairing iron-rich foods with vitamin C sources (like citrus fruits or bell peppers) can enhance iron absorption.
