Magnesium is an essential mineral vital for maintaining energy levels and overall health. It plays a key role in nerve and muscle function, regulates heartbeat and blood pressure, strengthens bones and the immune system, and may protect against certain health conditions like diabetes and stroke. Many adults don’t meet the recommended daily intake of magnesium, which ranges from 310 to 320 mg for most adult females and 400 to 420 mg for most males. Fortunately, numerous foods are rich in magnesium, making it easier to incorporate this crucial nutrient into your diet. This article explores top food sources of magnesium, along with their health benefits.
Seeds
Seeds might be small, but they are packed with magnesium. Adding seeds to your diet can significantly boost your magnesium intake.
