Magnesium is an extremely important mineral.
It's involved in hundreds of chemical reactions in your body and helps you maintain good health.
Unfortunately, many people don't reach the recommended daily intake of 400 mg (1).
However, eating foods high in magnesium can help you meet the daily requirement.
Here are 10 healthy foods that are high in magnesium.
1. Dark Chocolate
Dark chocolate is as healthy as it is delicious.
It's very rich in magnesium, with 64 mg in a 1-ounce (28 gram) serving. This amounts to 16% of the recommended daily intake (RDI) (2).
Dark chocolate is also in high in iron, copper and manganese, and it contains prebiotic fiber that feeds the friendly bacteria in your gut (3).
It's also loaded with beneficial antioxidants. These are nutrients that neutralize free radicals, harmful molecules that can damage your cells and lead to disease (4).
To make the most of these benefits, choose chocolate that contains at least 70% cocoa solids. A higher percentage is even better.
Bottom Line: A serving of dark chocolate provides 16% of the RDI for magnesium. It is also beneficial for gut health and heart health, and is loaded with antioxidants.
Avocados are also high in potassium, B-vitamins and vitamin K. And unlike most fruits, they're high in fat — especially heart-healthy monounsaturated fat.
In addition, avocado is an excellent source of fiber. In fact, 13 of the 17 grams of carbs in an avocado come from fiber, making it very low in digestible carbs.
Bottom Line: A medium avocado provides 15% of the RDI for magnesium. Avocados fight inflammation, improve cholesterol levels, increase fullness and are packed with several other nutrients.
Nuts are nutritious and tasty.
Several types are high in magnesium, including almonds, cashews and Brazil nuts.
For instance, a 1-oz (28-gram) serving of cashews contains 82 mg of magnesium, or 20% of the RDI (11).
Most nuts are also a good source of fiber and monounsaturated fat, and have been shown to improve blood sugar and cholesterol levels in diabetics (12).
Brazil nuts are also extremely high in selenium. In fact, just two Brazil nuts provide more than 100% of the RDI for selenium (13).
Bottom Line: Cashews, almonds and Brazil nuts are high in magnesium. A single serving of cashews provides 20% of the recommended daily intake.
Legumes are a family of nutrient-dense plants that include lentils, beans, chickpeas, peas and soybeans.
They're very rich in many different nutrients, including magnesium.
For instance, a 1-cup serving of cooked black beans contains an impressive 120 mg of magnesium, which is 30% of the RDI (17).
Bottom Line: Legumes are magnesium-rich foods. For example, a 1-cup serving of black beans contains 30% of the RDI.
Tofu is often a staple food in vegetarian diets due to its high protein content. It's made by pressing soybean milk into soft white curds and is also known as "bean curd."
A 3.5-oz (100-gram) serving has 53 mg of magnesium, which is 13% of the RDI (22).
One serving also provides 10 grams of protein and 10% or more of the RDI for calcium, iron, manganese and selenium.
Bottom Line: A serving of tofu provides 13% of the RDI for magnesium. It is also a good source of protein and several other nutrients.
Seeds are incredibly healthy.
Many contain high amounts of magnesium, including flax, pumpkin and chia seeds.
Pumpkin seeds are a particularly good source, with 150 mg in a 1-oz (28-gram) serving (25).
This amounts to a whopping 37% of the recommended daily intake.
In addition, seeds are rich in iron, monounsaturated fat and omega-3 fatty acids.
What's more, they're extremely high in fiber. In fact, nearly all of the carbs in seeds come from fiber.
Bottom Line: Most seeds are rich in magnesium. A 1-ounce serving of pumpkin seeds contains a whopping 37% of the RDI.
7. Whole Grains
Grains include wheat, oats and barley, plus pseudocereals like buckwheat and quinoa.
When grains are whole, they are excellent sources of many nutrients, including magnesium.
A 1-oz serving of dry buckwheat contains 65 mg of magnesium, which is 16% of the RDI (30).
Many whole grains are also high in B vitamins, selenium, manganese and fiber.
What's more, they do not contain gluten, so people who have celiac disease or gluten sensitivity can enjoy them too.
Bottom Line: Whole grains are high in many nutrients. A 1-oz serving of dry buckwheat provides 16% of the RDI for magnesium.
8. Some Fatty Fish
Fish, especially fatty fish, is incredibly nutritious.
Many types of fish are high in magnesium. These include salmon, mackerel and halibut.
Half a fillet (178 grams) of salmon contains 53 mg of magnesium, which is 13% of the RDI (35).
It also provides an impressive 39 grams of high-quality protein.
Fish is also rich in potassium, selenium, B-vitamins and various other nutrients.
These benefits have been attributed to the high amounts of omega-3 fatty acids.
Bottom Line: Fatty fish is exceptionally nutritious and a great source of magnesium and other nutrients. Half a fillet of salmon provides 13% of the recommended daily intake of magnesium.
Bananas are among the most popular fruits in the world.
They are best known for their high potassium content, which can lower blood pressure and is linked to a reduced risk of heart disease (40).
But you may not have heard that bananas also contain magnesium. One large banana contains 37 mg, or 9% of the RDI (41).
Bananas also provide vitamin C, vitamin B6, manganese and fiber.
Ripe bananas are higher in sugar and carbs than most other fruits, so they may not be suitable for people with diabetes.
However, when bananas are unripe, a large portion of their carbs are resistant starch, which doesn't get digested and absorbed.
Bottom Line: Bananas are a good source of several nutrients. One large banana has 9% of the recommended daily intake of magnesium.
10. Leafy Greens
Leafy greens are extremely healthy, and many are loaded with magnesium.
Greens with significant amounts of magnesium include kale, spinach, collard greens, turnip greens and mustard greens.
For instance, a 1-cup serving of cooked spinach has 157 mg of magnesium, or 39% of the RDI (44).
In addition, they're an excellent source of several nutrients, including vitamin A, vitamin C, vitamin K, iron and manganese.
Bottom Line: Leafy greens are a very good source of many nutrients, including magnesium. A 1-cup serving of cooked spinach provides 39% of the RDI, which is very high.
