This is because the development of the human brain and the maintenance of neurons require a large amount of calcium, and even the body's natural growth hormone hormone is an important component of calcium!

A child's digestive system is imperfect, and the ability to absorb calcium from food is low. As for the elderly, because of their age, the functional decline of the digestive system and the inability to absorb calcium normally, they can only meet their own needs through external supplements. ”

Li Baocheng raised his head and asked, "Second brother, you said so much. When is the best time for middle-aged and elderly people to supplement calcium? Is there a sign or something? ”

Li Yi thought for a while and nodded: "Yes, there is this sign of calcium supplementation."

It is said that this person first ages from the legs, and once the middle-aged and elderly people see that their legs begin to have loose skin, and the leg hair loss is very serious, this is a signal to supplement calcium.

Of course, don't supplement calcium too quickly at the beginning, you can make up for calcium through soy products and egg products.

If you take all kinds of calcium tablets as soon as you get started, it will cause a lot of pressure on the liver and kidneys, and even cause cardiovascular and cerebrovascular diseases due to too much calcium in the body in a short period of time. ”

"What? If you supplement too much calcium, can it also cause cardiovascular and cerebrovascular diseases? Su Haitang originally thought that she would have a meal to eat soy products in the future, and drink more water to prevent stones, but Li Yi's words made her heart tremble, this calcium supplement will cause cardiovascular and cerebrovascular diseases?

Li Yi: "Yes, the human body is a melting pot of balance.

If you take too much calcium, it will lead to a large loss of magnesium and zinc in the body.

Magnesium is a key element in maintaining stable energy metabolism in many internal organs such as the brain, heart, kidneys, and liver.

An important means of treating neurological diseases abroad is drugs that consume a large amount of magnesium.

In addition, the main cause of heart disease such as irregular heartbeat is the lack of magnesium in the body.

Zinc is an important element of human life activities, and zinc deficiency in the human body will lead to infertility.

For example, diabetic patients are unable to break down sugar in the body in time because of problems with insulin secretion, and one of the core elements of insulin is zinc.

Therefore, if there is more calcium, the magnesium to maintain the cardiac energy will be reduced, and the zinc element to maintain blood purification will also be reduced, and in the long run, cardiovascular and cerebrovascular diseases will occur due to excessive calcium supplementation. ”

Only then did everyone understand that this supplement of minerals should also be in moderation, which was too much.

"By the way, what's going on with the kid who eats hawthorn in the neighboring village? His family said that he also drank water a lot, why did he get kidney stones at such a young age? Li Baocheng asked again.

Li Yi explained: "Dad, that kid got kidney stones from eating hawthorn because he ate too much.

Hawthorn, eating less, can be appetizing and spleen, but eating too much will lead to excessive stomach acid, which affects the absorption of calcium.

As a result, the calcium that should enter the human organs is also transported to the kidneys in advance, so that the kidneys are overwhelmed, and the calcium gradually accumulates, forming kidney stones.

Another important reason is that the child eats hawthorn on an empty stomach every day, or consumes a large amount of it, which makes the acid-base balance in the body abnormal.

If the body is too acidic, it will lead to liver function impairment, the function of the liver and kidney is connected, and the liver damage will lead to kidney function decline, resulting in kidney stones. ”

"By the way, when you say this mineral, I think of what is the name of a very fashionable food nowadays?

Called selenium-containing foods? What's going on? Seems like this kind of thing is quite expensive? Su Haitang suddenly remembered something and asked with a smile.

Dong Xiaonan also responded: "Yes, yes, it is selenium-rich food!" This kind of food sells for a lot of money! It is said that it can fight cancer. ”

Li Yi smiled: "This matter involves another mineral: selenium.

Selenium is directly activated in cell function, selenium and zinc are important elements for the synthesis of human immune cells, and selenium is also a key core element of human immune function.

Saying that selenium is anti-cancer is a false proposition.

Because selenium itself has no effect, only when it is combined with zinc and other elements to form human immune cells, this has an anti-cancer effect. At the end of the day, it's the body's immune system that comes into play.

The reason why selenium can be anti-cancer is because many top anti-cancer drugs contain selenium. Moreover, scientific experiments have proved that the precursor of many cancer outbreaks is the lack of selenium in the human body.

Many of the foods we eat are rich in selenium, and they are all cheap normal foods.

So, don't be fooled by those selenium-rich foods, which are just fraudulent slogans shouted by merchants for promotion.

For example, nuts, peanuts, barley, beer, oats, fish, dried shrimp, and garlic are all selenium-rich foods, especially mushrooms, and shiitake mushrooms are currently the most selenium-rich foods. It is also known as a cheap anti-cancer drug! ”

When Su Haitang heard this, he patted his thigh and said with a smile: "Oh, after a long time, the whole grains around us are the best thing?"

No wonder people in the city are rushing to buy food from our village, our family used to be a lot of corn piled up in the yard.

This year, as soon as the second of your scenic spot development company emerged, those tourists not only wanted our local products here, but also our corn.

The people in the city drove their own cars, and the purchase price was high, and some even signed a purchase agreement, and every household was happy. The corn and wheat in the village do not have to worry about selling.

Although each car can only hold a few hundred catties, there are so many people that the grain in our village is almost empty. ”

Li Yi nodded and said: "The nutritional value of this corn is much higher than that of wheat, and corn is also a selenium-rich grain, plus corn contains a lot of high-quality dietary fiber, which is more beneficial to human digestion and absorption, so now rich people are popular to take corn as their staple food." ”

"Huh? So good? Wan Mengmeng's eyes lit up, looking at the corn tortillas on the side, she no longer disliked it as she did in the past, but had a kind of eager idea.

"Mom, make me tortillas in the future. Corn is so nutritious that I want to eat tortillas all at once. Wan Mengmeng took Su Haitang's arm and said coquettishly.

"This and that?" Su Haitang's head shook and rattle like a rattle, and explained: "No, no, the tortillas used to be eaten because there was no food at home, and the poor had nothing to eat.

Our family is not short of food, you are still pregnant, how can you eat tortillas?

No, my mother can't treat her daughter-in-law badly, let alone my grandson! ”

"Huh?" Wan Mengmeng originally wanted to have so much corn at home and supplement her nutrition well, but she didn't expect Su Haitang to refuse like this.

Li Yang smiled and explained to her in a whisper that these corn tortillas are the staple food eaten by the poor people in the village.

If others knew that Su Haitang took care of Wan Mengmeng with corn tortillas, they would be laughed at, and they would say that Su Haitang was not a good mother-in-law.

Li Yi smiled: "Mom, what age is this?" Do you care? ”

Su Haitang still disagreed: "No, no." Cornmeal is feed for pigs in the countryside, how can I give it to my daughter-in-law? No way! Say nothing! ”

Looking at Su Haitang's firm wording, Li Yang and his family were a little embarrassed, they wanted to eat some nutritious staple food, but they didn't expect to encounter this bluffing customs, how can this be done?

Looking at the old brother's eyes asking for help, Li Yi patiently explained: "Mom, don't say your words so absolutely.

Corn used to be the staple food of poor families, but you also have to admit that in the past, poor families often ate corn because they were in good health and did not get sick.

Who says the poor don't have anything good to eat? Hairy crabs, in the past, were caught from the river by the poor who could not afford to eat, but now what? Isn't it the same to be robbed by the rich?

Don't worry so much about eating, one thing is popular in an era, we can't lose ourselves.

My sister-in-law is now pregnant and needs to eat corn even more. Corn seeds contain a lot of minerals, far more than wheat, and the nutritional value alone is worth eating corn.

Moreover, the ratio of calcium, iron, magnesium and zinc in corn seeds is balanced, and there will be no loss of other minerals caused by calcium supplementation.

The most important thing is that corn contains a lot of substances that are beneficial to the development of the fetal brain, if you don't let your sister-in-law eat corn, you don't give your grandchildren nutrition? ”

Su Haitang was stunned when she heard this, and opened her mouth to refute, but supplementing her daughter-in-law with nutrition is a serious matter.

In the end, Wan Mengmeng got her wish, but Su Haitang also had conditions, only allowed to say it at home, not to go out.
