Symptoms of manganese deficiency

Manganese is a relatively common trace element and is also very important for human bones. When some bone development disorders occur, people often think of calcium. In fact, manganese also plays a relatively important role in bone development. If the body lacks manganese, it often leads to slower bone development and even causes various manifestations of rickets, which is relatively harmful to the health of the body.

Symptoms of manganese deficiency

In recent years, American scholars have discovered that there are osteoblasts and osteoclasts in bones. The physiological functions of the two are both opposite and complementary, and together they maintain bone metabolism. However, when the body is deficient in manganese, the activity of osteoclasts is enhanced, while the activity of osteoblasts is inhibited, the growth rate slows down, and bone formation disorders occur.

The dynamic balance originally established in the body is destroyed, and over time, the bones will become porous. Therefore, insufficient manganese in the body is also one of the factors of osteoporosis.

The role of manganese in the human body

1. It can promote the growth and development of bones. 2. Protect the integrity of granules in cells. , maintain normal brain function. 5. It can improve the body's hematopoietic function. 4. Maintain normal sugar metabolism and fat metabolism. 5. It can improve the body's hematopoietic function.

sex. The usual intake of manganese is 2 to 5 mg per day, and the absorption rate is 5% to 10%. If it is less than this amount, symptoms of manganese deficiency may occur. Symptoms of manganese deficiency can affect reproductive ability and may cause congenital malformations, abnormal bone and cartilage formation, and impaired glucose tolerance in offspring. In addition, manganese deficiency can cause neurasthenia syndrome and affect intellectual development. Manganese deficiency will also lead to reduced insulin synthesis and secretion, affecting glucose metabolism.

The daily manganese requirement for adults is 0.1 mg per kilogram of body weight. Among foods, tea, nuts, whole grains and dried beans contain the most manganese. The manganese content in vegetables and dried and fresh fruits is slightly higher than that in meat, milk and aquatic products. Fish liver and chicken liver contain more manganese than meat. A general mixed diet of meat and vegetables can provide 5 mg of manganese per day, which can basically meet the needs. Eating too much refined rice, white flour, meat and milk will reduce the manganese content. When a normal person experiences weight loss, sexual dysfunction, and premature graying of hair, insufficient manganese intake may be suspected.
