Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a crucial mineral that is essential for the proper functioning of the human body. Our bodies require it for numerous biochemical processes and to maintain overall health. It is naturally present in many foods, including green leafy vegetables, nuts, seeds, legumes, whole grains, and some seafood, according to seafood processing companies. However, some individuals may not get enough of this nutrient from their diet, and certain medical conditions or medications can affect magnesium absorption. In such cases, supplements may be recommended under the guidance of a healthcare professional.
Here are some key reasons why our bodies need this nutrient:
· Energy production: It plays a vital role in converting the food we eat into energy. It is involved in the synthesis and breakdown of ATP (adenosine triphosphate), which is the primary energy currency of cells.
· Muscle function: It is necessary for proper muscle function, including the contraction and relaxation of muscles. It helps regulate the movement of calcium in and out of cells, which is important for muscle contractions.
· Nerve function: It is involved in the transmission of nerve signals. It helps regulate the activity of neurotransmitters, which are chemicals that transmit messages between nerves and muscles.
· Bone health: It is a key mineral for maintaining strong and healthy bones. It works alongside calcium and vitamin D to support bone formation and mineralisation.
· Heart health: It plays a crucial role in maintaining a healthy heart. It helps regulate heart rhythm, supports blood vessel function, and helps maintain normal blood pressure levels.
· Protein synthesis: It is involved in protein synthesis, which is the process of building and repairing proteins in the body. Proteins are essential for the structure, function, and regulation of tissues and organs.
· DNA and RNA synthesis: It is required for the synthesis of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), which are the genetic materials of our cells. It helps in the replication and transcription of genetic information.
· Enzyme function: Many enzymes in our body depend on it as a cofactor to carry out their biological functions. Enzymes are involved in various chemical reactions necessary for metabolism, digestion, and other essential processes.
It is important to note that while magnesium is beneficial for the body, excessive intake of supplements can lead to adverse effects. It is always advisable to consult with a healthcare professional to determine the appropriate intake level for your individual needs.
What kinds of seafood contain magnesium?
Several types of seafood offered by any seafood export company or the best yellowfin tuna exporters, contain magnesium. Here are a few examples:
· Mackerel: Mackerel is a fatty fish that is high in this nutrient. It is also a good source of omega-3 fatty acids, which have numerous health benefits.
· Salmon: Salmon is another fatty fish that is not only rich in omega-3 fatty acids but also contains a good amount of magnesium.
· Halibut: Halibut is a lean fish that provides a moderate amount of it along with other nutrients like protein and vitamin B12.
· Tuna: Tuna is a popular fish that contains it. It is also a good source of protein and other essential nutrients.
· Sardines: Sardines are small oily fish that are packed with this nutrient. They are also rich in omega-3 fatty acids and vitamin D.
· Shrimp: Shrimp is a shellfish that contains magnesium as well as other important nutrients like protein and selenium.
The magnesium content can vary depending on the specific species of seafood and the way it is cooked or prepared. Additionally, be aware of any potential mercury contamination in certain seafood and consume them in moderation as part of a balanced diet.
What are the negative effects of consuming magnesium?
While magnesium is generally safe and beneficial for the body, consuming excessive amounts of it, particularly through supplements, can have some negative effects. Here are a few potential issues associated with excessive intake of it:
· Gastrointestinal issues: High doses of these supplements can cause diarrhoea, abdominal cramping, and nausea. These gastrointestinal symptoms are more likely to occur when it is consumed in the form of certain laxatives or poorly absorbed compounds.
· Electrolyte imbalances: Excessive intake can disrupt the balance of other minerals, such as calcium and potassium, in the body. This can interfere with normal muscle and nerve function.
· Interference with medication absorption: It can interact with certain medications, reducing their absorption and effectiveness. If you are taking any medications, it is important to consult with a healthcare professional to determine any potential interactions.
· Kidney complications: Individuals with impaired kidney function may have difficulty excreting excess magnesium, leading to magnesium accumulation in the body. This can potentially contribute to kidney problems in such cases.
These negative effects are more likely to occur with excessive magnesium intake from supplements rather than from dietary sources. When it is obtained through a balanced diet, it is generally well-tolerated and safe. Hence, if you are considering magnesium supplements or have concerns about your intake, it is always recommended to consult with a healthcare professional who can assess your individual needs and guide you on the appropriate dosage. They can also consider any underlying medical conditions or medications you may be taking to ensure that magnesium supplementation is safe for you.
As with any kind of nutrient, too much of it can have bad effects on your overall health, hence make it a point to speak to a specialist in nutrition or your family doctor before taking such decisions.
