People who suffer from headaches are usually lacking magnesium. Luckily, increasing levels of the mineral in your body can help fight dull aches, or even sharp migraines. Cereal is a fantastic source of magnesium (we love and recommend trying Kashi Organic Promise Cranberry Sunshine, or Low Carb Special K). Leafy green veggies and nuts are also high in the mineral. Many people use ginger to thwart and prevent migraines. And calcium, found in skim milk, yogurt, etc. is another headache-stomper.
