Women are especially prone to iron deficiency because of monthly blood loss through menstruation. So, keep your energy levels high by eating more oysters, lean cuts of beef, liver, and canned tuna.
You can get plenty of iron from plant-based foods too. Legumes, spinach, baked potatoes, cashews, raisins and broccoli are all good sources.
Pro tip: if you rely on plant-based foods for your iron intake, be sure to eat them along with foods that are high in vitamin C (it helps you absorb more plant-based iron), such as oranges, strawberries, peppers and grapefruits.
