Magnesium-rich foods: leafy greens, nuts, legumes, whole grains
Magnesium is an essential nutrient that most people don't get enough of. It is a vital mineral that helps the body function properly. The recommended daily allowance is 400–420 mg for men and 310–320 mg for women, but many people do not meet these targets through their diet alone.
Leafy greens
Leafy greens, such as spinach, kale, collard greens, turnip greens, and mustard greens, are excellent sources of magnesium. They are also rich in other nutrients, including iron, manganese, and vitamins A, C, and K. Additionally, they contain beneficial plant compounds that help protect your cells from damage and may reduce cancer risk.
Nuts
Nuts, including almonds, cashews, peanuts, and toasted nuts, are a great source of magnesium. They can be enjoyed as a healthy snack or added to dishes for extra texture and flavor.
Legumes
Legumes, such as black beans, are another good source of magnesium. They are also rich in fiber and have a low glycemic index, which may help lower cholesterol levels. Tofu, made from soybeans, is another legume that contains magnesium, along with protein, calcium, iron, manganese, and selenium.
Whole grains
Whole grains, such as wheat, oats, barley, buckwheat, and quinoa, are excellent sources of magnesium. For example, a 1-cup serving of cooked buckwheat contains 86 mg of magnesium. Whole grains have also been shown to reduce inflammation and decrease risk factors for heart disease.

Recommended daily allowance: 400-420mg for men, 310-320mg for women
The recommended daily allowance of magnesium is 400-420mg for men and 310-320mg for women. This can be achieved through diet, and it is preferable to get your vitamins and minerals from food.
Magnesium is a mineral that is crucial for the body's functions. It is used for blood glucose control, blood pressure regulation, energy production, muscle and nerve function, bone development, and relaxation, among other things. A deficiency in magnesium can cause fatigue, low appetite, and muscle spasms, although this is rare.
To add more magnesium to your diet, consider the following foods. Dark chocolate is very rich in magnesium, with 65mg in a 1-ounce (28g) serving. Spinach is another great source of magnesium, with 158mg in a 1-cup (180g) serving. Other leafy greens, such as kale, are also good sources. Legumes, such as black beans, are another abundant source of magnesium, with 120mg in a 1-cup (172g) serving. Tofu is another option, with 35mg in a 3.5-oz (100g) serving.
There are also many whole grains that are rich in magnesium, including quinoa, shredded wheat, wheat, oats, barley, and buckwheat. Fish, especially fatty fish, are also high in magnesium. Salmon, for example, has 30mg in a 3.5-oz (100g) serving. Dairy products also tend to be rich in magnesium.

Magnesium supplements: may cause nausea, cramps, and diarrhoea
Magnesium is a vital mineral for normal blood pressure, strong bones, steady heart rhythms, blood glucose control, energy production, muscle and nerve function, bone development, and relaxation. While it is rare to have a magnesium deficiency, it can occur and cause symptoms like fatigue, low appetite, and muscle spasms.
Magnesium supplements are often suggested for people with certain health conditions or specific medications. However, taking too much magnesium in supplement form can lead to an overdose with side effects and, in extreme cases, life-threatening risks. The recommended daily allowance is 400–420 mg for men and 310–320 mg for women, and it is advised not to exceed these amounts.
Taking a higher dose of magnesium supplements may cause gastrointestinal issues, such as nausea, abdominal cramping, and diarrhoea. This is due to magnesium's effect on the gut, attracting water into the intestines and leading to increased bowel movements. The more magnesium one takes, the higher the chances of experiencing these side effects.
To avoid these digestive symptoms, it is recommended to get magnesium from food sources, as it is challenging to get an overdose from dietary magnesium. Magnesium-rich foods include dairy products, legumes, nuts, seeds, whole grains like quinoa and shredded wheat, and leafy greens such as spinach and kale.

Health risks of magnesium deficiency: inflammation, osteoporosis, high blood pressure
Magnesium is an essential macromineral that plays a crucial role in several bodily functions, including blood glucose control, blood pressure regulation, energy production, muscle and nerve function, bone development, and more. While magnesium deficiency is relatively rare, certain individuals are more susceptible to it due to specific illnesses or medications they may be taking.
Health Risks of Magnesium Deficiency
Inflammation
Magnesium deficiency is associated with increased levels of inflammation markers in the body. Inflammation has been linked to major health conditions such as heart disease, diabetes, and certain cancers. Therefore, maintaining adequate magnesium intake may help reduce the risk of these inflammatory-related conditions.
Osteoporosis
Magnesium plays a vital role in bone health and bone mass density. A deficiency in magnesium can contribute to osteoporosis by affecting crystal formation and bone cells. It also impacts the secretion and activity of parathyroid hormones, which regulate calcium homeostasis, further influencing bone health.
High Blood Pressure
Magnesium is essential for maintaining normal blood pressure. A deficiency in magnesium can lead to high blood pressure or hypertension, which is a strong risk factor for various cardiovascular complications. Research suggests that a diet rich in magnesium may help prevent high blood pressure, especially in individuals with prehypertension.
Adding Magnesium to Your Diet
To ensure adequate magnesium intake, it is recommended to include magnesium-rich foods in your diet. Dairy products, legumes, nuts, seeds, whole grains (such as quinoa and shredded wheat), and leafy greens (such as spinach and kale) are excellent sources of magnesium. These foods provide not only magnesium but also other essential nutrients, contributing to a healthy and well-rounded diet.
While magnesium supplements are available, it is generally recommended to obtain this mineral from natural food sources whenever possible. Supplements may be considered in cases where dietary intake is insufficient or impractical, but it is important to consult with a healthcare professional before taking any supplements, especially if you have existing health conditions or are taking medications.

Magnesium-rich foods: fatty fish, dark chocolate, avocados
Magnesium is an essential macromineral that supports a variety of bodily functions, including a healthy immune system, improved bone health, and potentially fighting certain cancers. Many people do not get the recommended daily allowance of magnesium, which is 400–420 mg for men and 310–320 mg for women.
Fatty fish, such as salmon, mackerel, and halibut, are excellent sources of magnesium. A 3.5-oz (100-g) serving of cooked salmon provides 30 mg of magnesium, along with 22 g of high-quality protein. Fish is also rich in other nutrients like potassium, selenium, and B vitamins.
Avocados are another tasty and nutritious way to increase your magnesium intake. They have been shown to reduce inflammation, improve cholesterol levels, and increase feelings of fullness after meals.
Dark chocolate, with at least 70% cocoa solids, is a sweet treat that can boost your magnesium levels. A 1-ounce (28-gram) serving typically contains around 64–65 mg of magnesium, along with beneficial antioxidants that can improve blood flow, lower blood pressure, and reduce inflammation.
In addition to these specific foods, there are many other magnesium-rich options, including leafy greens (such as spinach, kale, and Swiss chard), legumes (like black beans and soybeans), nuts and seeds (including almonds, cashews, and pumpkin seeds), and whole grains (such as wheat, oats, and quinoa). Incorporating a variety of these foods into your diet can help ensure you're getting enough magnesium while also benefiting from the other nutrients they provide.
