In food, minerals are widely distributed and generally meet the organism's needs, but some are easily deficient, such as calcium, iron, zinc, iodine and selenium. Mineral nutrient fortification agents, also known as inorganic salts, are indispensable for constituting the body's tissues and maintaining normal physiological activities. More varieties of inorganic salts for food additives. At present, mineral nutrient fortification is in more applications of iron fortification, zinc fortification, calcium fortification and iodine fortification.

What are the 7 main minerals?


Magnesium strengthens teeth and bones, facilitates muscle relaxation and maintains muscle health. It also protects the heart and nervous system and aids in the treatment of PMS. When the body does not have enough magnesium intake can cause weakness of limbs, muscle tremors or spasms, high blood pressure, insomnia, depression, etc. Can get magnesium from raisins, green beans peanuts, pecans, almonds, malt and other foods.


Potassium can transfer nutrients into the cells, help metabolic waste transport out of the cells, promote muscle and nerve health, maintain fluid balance, facilitate muscle relaxation and insulin secretion, help regulate blood sugar. In addition, potassium is also involved in metabolism, protects heart function, promotes gastrointestinal motility, and helps eliminate metabolic waste from the body. When potassium is lacking in the body, it can cause muscle weakness, tingling in the hands and feet, irritability, nausea and vomiting, bloating and confusion. It can be obtained from cucumber, pumpkin, honey, cabbage, celery and other foods.


Calcium is the building block of bones, can protect the heart, nerves and skin, reduce muscle and bone pain, while maintaining acid-base balance. When the body's calcium intake is not enough will cause muscle cramps or tremors, increase the risk of tooth decay and high blood pressure and arthritis. The daily intake of calcium should be 800 to 1000 mg. Calcium can be obtained from foods such as milk, cabbage, wheat, pumpkin seeds and almonds.


Sodium maintains water balance in the body, prevents dehydration, helps nerve activity and muscle contraction, and also transports nutrients into cells. Sodium deficiency in the body can cause dizziness, low blood pressure, rapid pulse rate, lack of appetite, nausea and vomiting, body wasting and muscle cramps and headaches. A daily sodium level of 2400 mg or less is sufficient. If large amounts are consumed, it may cause high blood pressure, kidney disease or edema. Sodium can be obtained from foods such as sodium salt and kimchi.


Iron is the main component of hemoglobin, involved in oxygen and carbon dioxide exchange and transport. When the body lacks iron can cause pallor, anemia, general weakness, physical fatigue and nausea and vomiting. Iron can be obtained from animal blood, animal liver, lean meat, red dates and other foods.


Zinc is an essential substance for growth and development, promoting wound healing and relieving stress, as well as promoting brain and nervous system health. It can be obtained from foods such as pecan whole grain cereals, oysters, peanuts, almonds and oats.


Selenium has a very powerful antioxidant effect, can protect the body from free radical damage, while reducing the inflammatory response, enhance resistance and immunity.
