Bananas are among the most popular fruits in the world. They’re best known for their high potassium content, which can lower blood pressure and is linked to a reduced risk of heart disease ( 40 ). But they’re also rich in magnesium — one large banana packs 37 mg, or 9% of the RDI (41).

As magnesium deficiency worsens, symptoms may include:

• numbness.
• tingling.
• muscle cramps.
• seizures.
• muscle spasticity.
• personality changes.
• abnormal heart rhythms.

12 foods that contain magnesium: Fruit (figs, avocado, banana and raspberries) Nuts and seeds. Legumes (black beans, chickpeas and kidney beans) Vegetables (peas, broccoli, cabbage, green beans, artichokes, asparagus, brussels sprouts)

Sweet potatoes contain a significant amount of magnesium, which is an essential mineral for normal body functioning (13) . One of the most important benefits of magnesium is that it helps reduce stress and anxiety (14).

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).

Other vitamins and minerals in watermelon are also good for your heart. These include vitamins A, B6, C, magnesium and potassium ( 1 ).

Here are Taylor’s top picks.

3. Fiber-rich whole grains.
4. Low-fat dairy products.
