What are minerals? Do you lack it?

summary

Minerals commonly used in daily life are actually inorganic elements, which are divided into major elements and trace elements. Some inorganic elements are essential nutrients to maintain human life activities and health, also known as micronutrients. They must be obtained through food. Only when we understand the mineral can we reasonably apply and supplement them. Let's have a look

What are minerals? Do you lack it?

The first is to understand what minerals are. They are divided into major elements and trace elements. Major elements include: sodium, potassium, calcium, phosphorus, magnesium, etc.; trace elements refer to the chemical elements whose daily requirement is less than 100mg, including: iron, iodine, zinc, fluorine, selenium, copper, manganese, etc.

Second: what minerals do we Chinese lack? An assessment report has pointed out that in China, due to iodine deficiency during pregnancy, 2 million newborns are at risk of brain development damage every year. 40% - 60% of children aged 6-24 months are at risk of brain dysplasia due to iron deficiency. At the Symposium on micronutrients and national health held in Beijing in July 2002, experts pointed out that the calcium requirement of Chinese people is 50%. In the "China nutrition improvement action plan", it is mentioned that 80 million middle-aged and elderly people in China suffer from osteoporosis, ranking first in the world, which is related to the lack of calcium and other trace elements.

Third: understand which diets and behaviors damage minerals? Daily diet provides all kinds of minerals for our body, but at the same time, some habits and dietary behaviors in daily life also greatly damage the absorption of these mineral nutrients, and even lead to the lack of minerals. drink wine. Alcohol in wine affects the absorption of calcium, potassium, zinc, iron and magnesium. Smoking. Nicotine in tobacco destroys selenium. Coffee. Caffeine reduces the absorption of calcium, potassium and iron. sleeping pill. Taking sleeping pills can block and reduce calcium absorption. antibiotic. Taking antibiotics can reduce the absorption of calcium, magnesium and iron.

matters needing attention

It is found that human aging is closely related to mineral nutrients: calcium, zinc, selenium, manganese, chromium, iron, cobalt and strontium can enhance human immune system and prevent aging and disease; copper and cadmium are easy to promote aging and disease. The contents of manganese, iron, strontium and cadmium in the hair of the centenarians in Hubei are high, while the contents of zinc, iron, cobalt and nickel in the blood of the centenarians in Shanghai are high;
