6 Facts About Magnesium Everyone Needs to Know

Magnesium (Mg2+) is an essential macronutrient that plays a key role in the functioning of the body. Unlike micronutrients, macronutrients make up a significant portion of our body and are needed in larger quantities, although these quantities still remain at the milligram level per day. The body's need for magnesium significantly exceeds the need for micronutrients such as zinc or iron. Given its importance, it is worth paying attention to your diet to ensure sufficient magnesium intake, which promotes normal metabolism and maintains health.

Magnesium plays a key role in the functioning of the human body. Without this mineral, more than 300 enzymes cannot function, which disrupts the transmission of nerve impulses and muscle contraction. A lack of magnesium leads to disruptions in intracellular processes, resulting in impaired protein synthesis and energy production. Ensuring the body has a sufficient amount of magnesium is essential for maintaining healthy nervous and muscular systems, as well as for optimal cellular function.

The third fact: the most significant amount of Mg2+ accumulates in bones, where about 60% of this mineral is stored. At the same time, only 1% of magnesium circulates in the blood.

The fourth, less pleasant fact about magnesium is that in just 10 minutes of nervous tension, we can lose our daily requirement of this mineral. Under stress, the kidneys actively remove magnesium from the body. A magnesium deficiency, in turn, leads to a decrease in stress resistance and a deterioration in overall health. Maintaining normal magnesium levels in the body is important for stress management and maintaining psychoemotional balance.

Over the past hundred years, magnesium intake in the human diet has decreased significantly, almost halving - from 400-500 mg to 175-225 mg per day. This decrease is explained by several factors. First, changes in agricultural practices and modern farming have depleted soils, reducing the magnesium content of grown foods. Second, increased consumption of processed and refined foods, which contain fewer natural minerals, also negatively impacts dietary magnesium levels. This deficiency can impact health, as magnesium plays an important role in maintaining various bodily functions, including metabolism and nerve and muscle activity. Given these factors, it is important to monitor magnesium intake and consider supplementing if necessary.

• Much of today's diet consists of refined foods, which are low in magnesium;
• Additives such as preservatives, leavening agents, and colorings "leach" the mineral from food.

Fast food and alcohol contribute to increased magnesium excretion from the body. These products can negatively impact levels of this important mineral, leading to deficiency. Magnesium plays a key role in maintaining health, participating in various physiological processes. Decreased levels can cause various problems, such as fatigue, muscle cramps, and a deterioration in overall well-being. Therefore, it is important to control fast food and alcohol consumption to maintain optimal magnesium levels in the body.

How Much Magnesium Should You Get from Food

According to the US National Institutes of Health (NIH), the recommended intake of magnesium varies depending on age and gender. Magnesium plays a key role in maintaining health, participating in more than 300 biochemical reactions in the body. It is necessary for the normal functioning of muscles and the nervous system, as well as for maintaining strong bones. Regular magnesium intake can help prevent various diseases, including cardiovascular disease and osteoporosis. To ensure optimal magnesium levels, it is recommended to include foods rich in this mineral in your diet, such as nuts, seeds, whole grains, green leafy vegetables, and legumes. Your need for magnesium increases, especially if you live in a hot climate, are active in sports, or experience constant stress. Pregnant and breastfeeding women should also increase their magnesium intake to 310 to 400 mg per day. This is because magnesium plays a key role in maintaining overall health and well-being, and a deficiency can negatively impact the body.

Which foods are high in magnesium?

Here is a list of foods rich in magnesium. Magnesium is an essential mineral that helps maintain health by participating in various biochemical processes in the body. Including foods containing magnesium in your diet can help strengthen the immune system, improve sleep quality, and reduce stress levels. Such foods include nuts, seeds, dark green leafy vegetables, legumes, whole grains, fish, and bananas. Regular consumption of these foods can promote proper body function and improve overall well-being.

According to information from the United States Department of Agriculture (USDA) National Nutrient Database, the nutrient content of various foods plays a key role in maintaining human health. This data is an important resource for consumers, nutritionists, and dietitians looking to create a balanced menu and ensure optimal intake of vitamins and minerals. Proper use of this information helps better understand which foods can promote health and prevent disease. Therefore, understanding the nutrients represented in the USDA database is an essential part of a balanced diet.

Wheat bran is a versatile product for those who carefully monitor their calorie intake and strive to maximize the benefits of their food. The high fiber content of bran helps slow the absorption of cholesterol and glucose, which is important for maintaining normal blood sugar levels and cholesterol control. Thanks to dietary fiber, some calories are not digested in the intestines and are eliminated from the body in the feces. Furthermore, wheat bran is a rich source of magnesium, making it a valuable addition to the diet. Including bran in your daily diet can help improve digestion and overall health.

The average magnesium content of wheat bran produced on Russian soils is approximately 448 mg per 100 grams. This is slightly lower than that found in European-grown bran, where magnesium concentrations reach approximately 600 mg per 100 grams. Such differences in mineral content may be due to differences in soil, climate, and production technologies. Wheat bran is a valuable source of magnesium, which is essential for maintaining health, and it's worth considering these factors when choosing a product. Whole grain bread is made from coarsely ground flour that retains the wheat bran. At first glance, it may seem that bran and whole grain bread are equivalent sources of magnesium, but there is an important difference. Magnesium is absorbed in greater quantities from whole grain bread. This is because many plant foods contain magnesium along with chelators, substances that bind other compounds. Wheat bran contains both magnesium and its chelator, phytic acid. When whole-grain flour is used in dough production, the fermentation process can reduce phytic acid content by 52–71%, making the mineral more easily absorbed. Therefore, whole-grain bread is a more valuable source of magnesium than bran.

One serving of cocoa, consisting of two tablespoons of cocoa powder, provides 10% of the daily value of magnesium. If hot drinks aren't your favorite, cocoa powder can be added to smoothies, Greek yogurt, homemade baked goods, oatmeal, and even a glass of wheat bran. When choosing cocoa powder, it's important to pay attention to its quality. Cocoa powder is obtained from the cake formed during the extraction of butter from cocoa beans. This butter contains the essential nutrients. Depending on the oil content in the powder, there are three types: full-fat (20-22% oil content), semi-fat (14-17%), and low-fat (less than 14%). Choosing the right cocoa powder will allow you to maximize its beneficial properties and enrich your diet. Sunflower seeds can be eaten raw or roasted. However, roasted seeds are preferable, especially if there are concerns about storing raw seeds. Raw seeds can become moldy, making them less safe to eat. 100 grams of seeds contain 9% of the daily value of magnesium, making them a healthy source of this mineral. However, it's important to remember that sunflower seeds are high in calories. For example, just a quarter cup of seeds contains about 165 calories, which is comparable to the calorie content of 100 grams of beef. Consider this when planning your diet to avoid excess calorie intake.

Almonds stand out from other nuts due to their high magnesium content and unique fat-burning properties. A study conducted by Korean scientists on 169 participants of both sexes confirmed this effect. The results were published in the journal Nutrition Research and Practice. Participants who consumed 56 grams of almonds daily demonstrated a decrease in fat mass and an improved blood lipid profile. This makes almonds not only tasty but also a healthy addition to the diet, helping to maintain a healthy weight and improve metabolism.

If you feel calm after eating a peanut butter sandwich, know that this is due to the high magnesium content. Magnesium plays an important role in maintaining psycho-emotional balance and promotes relaxation. Peanut butter, rich in this mineral, can be an excellent addition to your diet for improving mood and reducing stress.

Chocolate is often not perceived as a healthy product, and this is due to the fact that most people choose its sweet varieties. Low-quality chocolate may contain butterfat, vegetable oils, and artificial colors and flavors. Meanwhile, chocolate with a cocoa content of at least 75% is considered high-quality. This chocolate retains fiber and beneficial micronutrients. Research from Harvard University shows that one-quarter of a bar of dark chocolate contains 64.6 mg of magnesium, which is 15% of the daily value. Choosing dark chocolate not only satisfies your sweet tooth but also offers certain health benefits due to its high nutrient content. One serving of black beans contains 120 grams of magnesium, which satisfies approximately 20% of the daily requirement for this important mineral. Cooked beans are recommended, as canned versions often contain a lot of salt. While salt helps extend the shelf life of the product, it can reduce the bioavailability of magnesium. When choosing canned beans, pay attention to the label and look for a product marked "no salt added" to preserve the maximum amount of nutritional value.

This product is essential for people with an intolerance to gluten, a protein found in grains such as wheat. Buckwheat is gluten-free, making it an excellent source of magnesium. One serving of buckwheat (168 grams) contains 85.7 mg of magnesium, which helps maintain health. Due to its nutritional properties and the absence of gluten, buckwheat is an ideal choice for those watching their diet.

Rospotrebnadzor strongly recommends eating cereals that require cooking. These cereals, unlike processed foods, simply need to be poured with boiling water; they contain more healthy carbohydrates and have a higher nutritional value. Choosing cooked cereals improves digestion and maintains energy levels throughout the day. Therefore, it's worth choosing this option for a complete and healthy diet.

The short cooking time of porridge indicates significant processing of the original grain, which leads to a decrease in the content of active substances. The longer the grain is cooked, the more its nutritional value is lost.

Sea and ocean fish are a source of healthy fats, vitamins, and minerals. In cold waters, fish accumulate healthy fats that benefit the body. For example, just one 100-gram serving of salmon provides 7% of the daily value of magnesium, which is especially important for maintaining health. Vitamin B6, found in fish, promotes better absorption of magnesium by the body's cells. Thus, eating sea fish not only enriches the diet but also promotes improved absorption of important micronutrients.

Banana is a healthy fruit rich in magnesium and potassium. These minerals play a key role in maintaining a normal heart rhythm and blood pressure. Regular consumption of bananas may help improve heart health and reduce the risk of cardiovascular disease.

Bananas often get a bad rap due to their high sugar content. However, this only applies to ripe bananas. Green bananas, on the other hand, contain more fiber and much less sugar, making them suitable even for people with diabetes. They can be an excellent option for a healthy diet, providing essential energy and nutrients without a sharp rise in blood sugar.

Kiwi was originally called the Chinese gooseberry. The fruit received its modern name thanks to New Zealand exporters, who named it after the flightless kiwi birds native to New Zealand. Although kiwi contains a relatively small amount of magnesium—only 14–17 mg per 100 grams—this mineral is absorbed much better from it than from other sources. Kiwi is also rich in vitamins, especially vitamin C, and fiber, making it beneficial for maintaining health. Eating kiwi can help improve digestion and strengthen the immune system. Seaweed is last on our list for a reason. It contains a high concentration of magnesium—approximately 600 mg per 100 g—but absorption of this mineral in the body is extremely low, less than 5%. This is due to the presence of dietary fiber, which hinders magnesium absorption. Nevertheless, we recommend adding seaweed to your diet, as it is beneficial for the gut microbiota. The magnesium content in them should be considered as an additional benefit.

Spinach, like seaweed, has its own characteristics in the absorption of nutrients. In spinach, phytic acid binds magnesium, which can reduce its availability to the body. However, phytic acid also has beneficial properties. Research by Harvard Medical School suggests that phytates, which include phytic acid, can slow the absorption of cholesterol. This discovery underscores the importance of a balanced diet and variety to maximize the benefits of spinach and other phytate-containing foods.

Where else can you find magnesium and how can you get more of it?

About 10% of magnesium comes from drinking water, but the amount can vary significantly depending on the type of water. Most bottled waters do not contain high levels of magnesium, typically less than 20 mg/L. In regions with calcareous soils, magnesium levels in tap water can reach 30 mg/L. Such water is considered hard—it can negatively affect the operation of household appliances and contribute to dry skin or hair. However, it is worth noting that hard water is beneficial for the body due to the presence of essential minerals.

To increase your magnesium intake, you need to make changes to your diet and lifestyle. Include magnesium-rich foods in your menu, such as nuts, seeds, legumes, leafy green vegetables, whole grains, and bananas. Magnesium supplements, if needed, are also worth considering. Regular exercise and stress management also promote magnesium absorption. Drink enough water, as dehydration can negatively affect magnesium levels in the body. Remember that a varied diet plays a key role in maintaining optimal magnesium levels.

• Drink mineral water. There are low-, medium-, and highly mineralized waters, and not all are rich in magnesium. Jermuk water contains up to 200 mg of magnesium per liter, Borjomi - up to 150 mg, Essentuki - 75 mg, and Donat water [7] - up to 1100 mg.
• Eliminate magnesium "displacers." Avoid colored confectionery, carbonated drinks, canned goods, caffeinated drinks, energy drinks, and alcohol. Their presence in the diet either prevents magnesium from being absorbed [5] or accelerates its elimination from the body.
• Do not take medications unless absolutely necessary. If you have a habit of immediately taking a heartburn medicine or antibiotics for a cold "just in case," remember that the pill often takes away a "piece" of magnesium. It has been proven that antibiotics, proton pump inhibitors, which reduce gastric acidity, and diuretics can increase magnesium loss [24].
• Add calcium-rich foods to your diet. Magnesium is better absorbed [25] from food together with calcium, so be sure to add its sources to your menu - vegetables, leafy greens, cheese, cottage cheese and other fermented milk products.

In conclusion, it should be emphasized that obtaining magnesium from food minimizes the risk of excess of this mineral in the body. In contrast, taking magnesium supplements can lead to unwanted effects such as abdominal pain, constipation, nausea, vomiting, and flatulence. Therefore, it is important to consult a doctor before starting such supplements, especially if you have been diagnosed with magnesium deficiency (hypomagnesemia). Ensuring optimal magnesium levels in the body is important for maintaining health, and a proper approach to obtaining it can help avoid potential problems.

Magnesium deficiency symptoms are often mistaken for simple fatigue, making proper diagnosis difficult. To fully understand the body's magnesium status, specialized testing is necessary. Since magnesium concentrations in cells are higher than in the blood, standard testing may not detect a deficiency. More accurate information about magnesium status can be obtained by measuring Mg2+ levels in red blood cells, nails, or hair. These methods of analysis allow us to more accurately assess magnesium reserves in the body and promptly detect its deficiency.

Spectral hair analysis provides valuable information about the amount of magnesium and other trace elements that a person has received over the past months and years. Since hair grows slowly, analyzing its composition helps determine when a deficiency of essential nutrients began and how severe it is. This research method is an effective tool for monitoring nutritional deficiencies and assessing overall health.
