Consuming spinach during lunch or dinner with citrus, bell peppers, or strawberries helps break the bond between iron and oxalates, significantly increasing the amount of iron your body can utilize.

Fat-Soluble Vitamins: The Nutrient-Absorption Window

These are fat-soluble nutrients, meaning they require a dietary fat to be absorbed into the bloodstream. The optimal time to eat spinach is during a meal that includes healthy fats like avocado, olive oil, or nuts.
