To ensure adequate magnesium levels, you need to include a wide range of magnesium-rich foods in your diet. Leafy green vegetables, especially spinach, are good sources of this important mineral. Legumes like beans and peas are also high in magnesium. Nuts, especially Brazil nuts and almonds, as well as hemp seeds, pumpkin seeds and flax seeds are also excellent sources. Whole grains, including brown rice and quinoa, increase your daily intake of magnesium. By including these foods in your diet, you can effectively prevent magnesium deficiency and improve your overall health.
