The Benefits of Eating Magnesium-Rich Foods:

Magnesium plays a critical role in energy generation, nerve functions, muscle actions, formation and release of neurotransmitters, and maintenance of bone mineral density. Some of its key benefits are:

1- Cardiovascular Health: 

Magnesium regulates heart rhythms and transports other electrolytes like potassium and calcium to generate membrane potential and control heart contractions. It stays in the powerhouse of the cell called mitochondria to generate energy. 

Moreover, magnesium diminishes heart-related risks. It regulates the tone of vessels and reduces the risk of calcification, formation of atherosclerotic plaques, and thrombosis. 

A deficiency of magnesium can lead to coronary artery disease, heart failure, and arrhythmias. Additionally, good serum magnesium levels decrease the risk of stroke. 

2-Bone Strength: 

Magnesium is essential for the maintenance of bone mineral density. People who take adequate levels of magnesium have a higher bone mineral density compared to those who are deficient. It plays a role in the absorption of calcium and its regulation. People with gut problems, type 2 diabetes, celiac disease, and Crohn’s disease are at a greater risk of developing magnesium deficiency

Approximately 60% of body magnesium is stored in the bones. It is essential for bone cells i.e., osteoblasts (bone-forming cells) and osteoclasts (cells that degrade the bones). It acts as a coenzyme for many reactions, including the synthesis of nucleic acids, proteins, and lipids. Besides this, magnesium prevents osteoporosis and other bone disorders. 

3- Mental Wellness

Magnesium intake can alleviate symptoms of depression and anxiety. It provides a calming effect on your brain and relieves stress. It is an essential nutrient in the formation and release of neurotransmitters. 

In the brain, it blocks NMDA (N-methyl D-aspartate) receptors to prevent anxiety. According to a research study, magnesium plays a vital role in nerve transmission, myelination of neurons, formation, and maintenance of synapses, and regulation of cholinergic and dopaminergic neurotransmitters. Moreover, it enhances learning ability, concentration, and long and short-term memory. 

4- Blood Sugar Balance: 

It’s crucial in modulating and maintaining blood sugar, especially for those with diabetes. It acts as a coenzyme in glycolysis and regulates insulin action. 

A low level of serum magnesium results in low tyrosine kinase activity, which impairs insulin action and develops insulin resistance in the body. Magnesium taurate is the best form of magnesium that manages glucose levels in the blood. An adequate level of magnesium enhances insulin sensitivity. 

How to Get More Magnesium in Your Diet?

While there are many ways to get more magnesium, adding natural sources of magnesium into your daily diet is the most convenient. The following are a few tips to get more magnesium in your diet: 

1- Take a variety of food: 

Add a variety of the foods listed above into your diet to get all essential nutrients. 

2- Home-cooked Delights: 

You can opt for home-cooked foods to get a maximum level of magnesium. You can take the above-mentioned natural sources of magnesium in the form of salads, smoothies, and shakes to enhance their taste. 

3- Minimize Processed Intake: 

Processed foods are usually deficient in magnesium and other essential nutrients. Try to avoid such foods to stay healthy and prefer nutrient-rich and magnesium-dense food.
