Magnesium and iron are examples of minerals found in food. They are essential nutrients that the body needs to function properly.
Magnesium in Food
Magnesium is found naturally in a variety of nutrient-dense foods such as whole grains, nuts, seeds (like pumpkin and flax seeds), legumes (e.g., beans, lentils, chickpeas), dark leafy greens (such as spinach), tofu, dark chocolate, and certain fruits like avocados and bananas. Magnesium plays a role in hundreds of biochemical reactions in the body, including energy production, muscle and nerve function, and bone health.
Iron in Food
Iron is also a vital mineral found in foods such as red meat, organ meats (like liver), seafood (including shellfish and fish), spinach, legumes, tofu, nuts, seeds, quinoa, and dark chocolate. Iron exists in two forms in food: heme iron, which comes from animal sources and is absorbed more easily, and non-heme iron, which comes from plant sources. Iron is crucial for oxygen transport in the blood and preventing anemia.
Both magnesium and iron are classified as minerals in the context of nutrients found in food. They contribute essential functions to human health and are present in a variety of animal- and plant-based foods.
