One of the most vital minerals that you should be consuming on a consistent basis is magnesium. Magnesium is involved in numerous functions in the body, having an integral role in over 300 different enzymatic reactions, with functions spanning from protein synthesis and blood sugar regulation to controlling blood pressure and conducting nerve and muscle impulses. Magnesium also forms a major structural component of bones and teeth. Not only that, but magnesium acts as an electrolyte, helping transport calcium and potassium ions across cell membranes, which is necessary to maintain a heartbeat, nerve impulses, and muscle contractions.
Unfortunately, studies have shown that nearly 50% of adults in the United States do not meet the recommended daily allowance (RDA) of magnesium, which is generally between 400-420 mg for men, depending on age. Endurance athletes are particularly prone to magnesium deficiencies due to the excess amounts lost during sweating. So, as a rule, your magnesium levels need to be even higher. The good news is that there are plenty of healthy foods high in magnesium.
Luckily, some of the best-tasting foods also happen to be the highest in magnesium content. Making sure to get plenty of these foods, especially for those who are athletes or workout 5+ times a week, is crucial for optimal health and wellness.
Regularly consuming foods high in magnesium can help ensure your body has a plentiful supply of this vital mineral. Keep reading for a list of the foods highest in magnesium and make room on your shopping list for a few of your favorites.
Nuts certainly have earned their well-deserved reputation of being nutritious superfoods, due to their rich content of many essential nutrients like omega-3 fatty acids and vitamin E. They are also good sources of magnesium. Brazil nuts are particularly high in magnesium, with 25% of the recommended daily allowance in a single ounce. Brazil nuts may be less popular than fan favorites like walnuts, but they have a delightfully creamy texture and mild flavor. Almonds and cashews also provide nearly 20% of the daily value of magnesium, and they are high in melatonin, so they may help you sleep at night.
Avocados, which are technically a fruit, are packed with vitamin E and the heart-healthy monounsaturated fats that help make the Mediterranean Diet so effective at reducing the risk of various lifestyle diseases. An avocado contains about 60mg of magnesium or 15% of the recommended daily allowance. Try adding avocados to salads, sandwiches, omelets, or even smoothies. They add a lush creaminess and provide plenty of satiety because of their fat and fiber.
Several whole grains are high in magnesium. Brown rice and buckwheat, for example, provide 86mg per cup, which is 20% of the recommended daily allowance. They also provide sustaining complex carbohydrates, B vitamins, and some fiber. Quinoa, which is usually grouped with whole grains but is actually a seed, is also packed with magnesium. One cup of cooked quinoa has nearly 30% of the RDA.
Lima beans are slightly sweet, starchy, rich legumes that work well with salads, succotash, and healthy soups. They are quite high in magnesium. One cup of cooked lima beans contains 126mg of magnesium, which is 30% of the recommended daily allowance. Other legumes are also good sources of magnesium. White beans have nearly as much magnesium as lima beans and are also one of the best dietary sources of potassium. Black-eyes peas, kidney beans, chickpeas, and lentils are rich in magnesium. Legumes are also packed with fiber, B vitamins, complex carbohydrates, and antioxidants.
Tofu is a great plant-based source of protein for vegans and vegetarians. It’s also rich in nutrients like calcium, selenium, iron, and manganese. It also contains healthy phytonutrients and antioxidants shown to support prostate health. Tofu is also quite high in magnesium. One cup of firm tofu has 146mg of magnesium, which is an impressive 35% of the recommended daily allowance. Moreover, the absorption of magnesium is enhanced when consumed with protein, so tofu may be one of the best dietary sources of magnesium.
Tuna and other fatty fish are among the best dietary sources of omega-3 fatty acids, which reduce inflammation in the body and support cardiovascular and brain function. They also provide vitamin D, a steroid hormone that is crucial for bone health and mood regulation. Tuna also happens to be a good source of magnesium. A 6-ounce fillet provides 109mg (26% of the RDA). Mackerel and pollock are also good sources of magnesium, and since fish is high in protein, magnesium absorption is enhanced in any of these options.
Spinach and other dark leafy green vegetables hit nearly all of the marks when it comes to nutrient content, which is why they are considered to be among the healthiest vegetables. Dark leafy greens contain water, fiber, B vitamins, vitamins A and K, iron, calcium, and yes, magnesium. One cup of cooked spinach contains an impressive 157mg of magnesium, which is nearly 40% of the recommended daily allowance. Swiss chard is right up there with 36% of the RDA in the same-sized serving. Kale, collard greens, and turnip greens are also high in magnesium.
Squash and pumpkin seeds are some of the best sources of zinc, among other key nutrients like omega-3 fatty acids, foods high in biotin, and antioxidants. One ounce of either pumpkin seeds or squash seeds contains 156mg of magnesium (37% RDA). Flax seeds and chia seeds are also high in magnesium, but hemp seeds actually top the chart, with a whopping 47% of the RDA in a single ounce. Consider using hemp protein powder in protein shakes or homemade protein balls.
Bananas may be most heralded for their high potassium content, but they also contain vitamin C and prebiotic fiber, which feeds your beneficial gut bacteria. One medium banana has about 40mg of magnesium, so consider having a banana as a pre-workout snack to give your body the electrolytes you need in case you work up a heavy sweat.
Non-fat or low-fat yogurt is a good source of magnesium. One cup has about 47mg. Yogurt is also a good source of zinc, an essential mineral that supports your immune system. Dairy products also can help you sleep well at night, as they provide melatonin and tryptophan, an amino acid that can encourage sleepiness.
Who doesn’t want another reason to enjoy some dark chocolate? You’re in luck. Not only is dark chocolate an excellent source of antioxidants, but it also is high in magnesium. A one-ounce serving of dark chocolate has 65mg (15% RDA) of magnesium.
