Fitness and calcium have such a close relationship

The human body must have enough calcium intake to have enough calcium salts deposited in the bones. According to research, bone strength is mainly formed between the ages of 12 and 18, that is, a person's peak bone density is closely related to calcium intake when they are young. If this opportunity is missed and stronger bones are not developed, it will not only affect height but also increase the risk of osteoporosis in later years. A short, hunched body is naturally incompatible with bodybuilding.

If calcium is deficient for a long time, the elasticity of the eyeball will decrease and the contraction function of the eye muscles will be impaired, causing some people to have large and lifeless eyes, or premature wrinkles at the corners of the eyes, and they are also prone to myopia.

Calcium deficiency can affect neuromuscular coordination. When the calcium ion concentration in the body fluid surrounding the nerves decreases, the excitability of the nerves will increase significantly, and symptoms such as irritability, hyperactivity, insomnia, numbness in the hands and feet, muscle cramps, and back and leg pain may occur.

Calcium deficiency can increase the permeability of cell membranes. Calcium ions play an important role in maintaining the integrity of cell membranes. Low calcium levels can increase the permeability of the skin and mucous membranes to water, reduce skin elasticity, and cause unexplained skin itching, edema, and skin urticaria.

Young women need to consume 20 to 30 grams of calcium during the entire pregnancy process, with an average of more than 100 mg per day. Calcium deficiency during pregnancy and increased vascular smooth muscle tension are one of the important causes of gestational hypertension and will also affect the normal development of the fetus.

Nowadays, calcium deficiency among young women is increasing day by day. The reasons are as follows:

One is that drinking coffee has become a fashion, and coffee stimulates the adrenal cortex and increases urine output. Adenosine in coffee can also accelerate the excretion of calcium in urine.

The second reason is that young girls love beauty but are afraid of getting fat. Many of them do not eat milk, pork liver, and soy products, but prefer to eat snacks, resulting in insufficient calcium intake.

The third is fear of sun exposure, which leads to insufficient synthesis of vitamin D in the body. It is currently believed that the basic measure for young women to supplement calcium should be to pay attention to food intake, among which milk should be the best source of calcium for the human body. Studies have shown that young women who drink milk are 5 cm taller than those who do not drink milk, have a 6% higher bone density, and their anemia rate drops from 28% to 0.
