For most middle-aged and elderly people, it is easy to fracture the waist and leg soreness. Many people believe that this is due to the brittle bones after aging. In fact, the reason for this phenomenon is related to the lack of calcium in the body.
If the blood calcium level in the human body is less than 2.18-2.63 mmol/L, it is impossible to maintain the normal function of the bone, making the bone more and more loose, resulting in the so-called "brittle bones" phenomenon.
So why is it easy to appear after the age?
With the increase of age, the body's functions will gradually decline, especially for the elderly over 60 years old, there will be a decrease in calcium absorption, but the loss of calcium is too large.
The reason for this situation, in addition to being related to aging factors, is also related to some bad eating habits in the elderly. For example, many elderly people will have long-term partial eating behavior, and the absorption of calcium will be greatly reduced, which will cause this phenomenon.
However, if you eat some foods that will cause a large amount of calcium loss in the body for a long time, the phenomenon of calcium deficiency will be aggravated, resulting in problems such as osteoporosis. In particular, the following types of foods, if the elderly often eat it, will lead to a large loss of calcium.
1. Rich in high-salt foods
For many elderly people, they especially like to eat some foods rich in salt in their daily lives, especially some pickled vegetables, which are deeply liked by the elderly.
However, the more table salt you consume, the more calcium you will excrete in your urine. And the more salt is ingested, the worse the body's ability to absorb calcium will be.
2. Foods rich in oxalic acid and phytic acid
Many elderly people pay special attention to dietary health, such as eating more vegetables in daily life, or almost vegetarian foods in three meals a day.
Although vegetables contain a lot of vitamins, they also contain a lot of oxalic acid and phytic acid. The content of oxalic acid and phytic acid in the body is too high, it will combine with the calcium in the body, and then form some substances that are difficult to be absorbed by the intestine and quickly excrete from the body, so that the elderly have calcium deficiency.
3. Foods rich in animal fats
The more animal fats you ingest, the faster your calcium will be lost. If you consume 80 grams of animal protein per day, you will lose 37 mg of calcium in the body.
In particular, some fatty meat and other foods contain a lot of fatty acids, these fatty acids will be decomposed after combining with calcium, and then quickly excreted with calcium, resulting in calcium deficiency in the human body.
4. Foods rich in high phosphorus
Appropriate supplementation of some phosphorus-rich foods can enhance the body's absorption of calcium.
But the ratio of calcium and phosphorus in the body should be maintained at 2:1, if the intake of phosphorus in the body exceeds the standard, such as eating too many canned foods, animal offal, hamburgers, French fries, the phosphorus content in these foods is particularly high, which will lead to an imbalance in the ratio of calcium and phosphorus, so that a large amount of calcium is "driven away".
All in all, for the elderly population, with the increase of age, the body's functions will decline, which will lead to excessive calcium loss. Coupled with the fact that the elderly will have some bad eating habits, the absorption of calcium will be reduced. In this way, the bones of the elderly will be too loose due to the lack of calcium in the body.
Especially for the elderly who often eat the above 4 types of food, the calcium loss in the body will be very fast. Therefore, the elderly population must reduce the intake of these foods, appropriately increase some milk, tofu, fish, shrimp skin and other foods, and pay attention to the appropriate increase in aerobic exercise, which can effectively prevent calcium deficiency in the body.
