The Importance of Iron After 6 Months:

Once babies reach 6 months, their natural iron stores from birth begin to decrease, which means it’s important to start offering iron-rich foods as part of their diet. Iron supports healthy brain development, red blood cell production, and energy.

This lentil soup is a fantastic way to introduce iron early on. Red lentils are one of the easiest plant-based sources of iron for babies, and they’re soft, mild, and easy to digest. The addition of healthy fats from olive oil also helps the body absorb iron more effectively. It’s a simple, wholesome meal that’s as nutritious as it is comforting.

Nutritional Benefits:

• Red lentils: Rich in iron, protein, and fiber to support growth and energy.

• Garlic: Provides antioxidants and boosts immune health.

• Olive oil: A source of healthy fats that support brain and heart development.

Together, these create a balanced, iron-rich meal perfect for babies just starting solids.

Serving Suggestions:

• 7–9 months: Serve as is or pureed.

• 9–12 months: Serve with small pieces of bread or soft veggies.

• Toddlers: Enjoy with a drizzle of olive oil, lemon juice, or croutons.

Substitutions & Add-Ins:

• Swap red lentils for yellow lentils or split peas for variety.

• Add carrots, onion or spinach for extra vitamins.

• Use avocado oil or ghee instead of olive oil.
