What are the ingredients in food that affect the bioavailability of calcium? What role do they play?

Calcium is essential for all cellular organisms. Calcium-bound proteins are found in muscles, nerves, mucus and bones. The average adult Hugh contains about 1200g of calcium, and adults need calcium per day.

Calcium maintains normal neuromuscular excitation and regular heartbeat. Calcium activates a variety of enzymes in the body, and calcium is also involved in inhibiting the absorption of poisons during blood coagulation. The human body is deficient in calcium, prone to rickets (children), osteomalacia and fractures (adults), hypertension, cerebrovascular diseases, etc. are also related to calcium deficiency.

Magnesium is an activator of many enzymes in the body and plays an important role in maintaining the normal physiological function of myocardium. Magnesium deficiency can lead to coronary artery disease, myocardial necrosis, depression, muscle weakness and dizziness. Adults need 200-300 mg of magnesium per day.

The role of potassium is:

Involved in the metabolism of carbohydrates and proteins.

Maintain normal osmotic pressure in cells.

Maintain neuromuscular stress and normal function.

Maintain the normal function of the heart muscle.

Maintain normal acid-base balance inside and outside cells.

The role of sodium is:

Regulates body hydration and osmotic pressure.

Maintain acid-base balance.

Sodium pump enhances neuromuscular excitability. Iodine is one of the essential trace elements in the human body, so what role does it have in the human body?

1. Regulate protein synthesis and decomposition: when protein intake is insufficient, thyroxine has the effect of promoting protein synthesis; When protein intake is adequate, thyroxine promotes the breakdown of protein (protein food).

2. Regulate water and salt metabolism: thyroxine can promote the water and salt in the tissue to enter the blood and be discharged from the kidneys, and when it is deficient, it can cause water and salt retention in the tissue, and the tissue fluid containing a large amount of mucin appears in the interstitial space, resulting in myxedema.

3. Promote biological oxidation: thyroxine can promote biological oxidation in the tricarboxylic acid cycle, coordinate the coupling of biological oxidation and phosphorylation, and regulate the conversion of energy (energy food).

4. Enhance the activity of enzymes: thyroxine can activate more than 100 enzymes in the body, such as cytochrome enzyme system, succinate oxidase system, alkaline phosphatase, etc., which play a role in substance metabolism.

5. Promote sugar and fat metabolism: thyroxine can accelerate the absorption and utilization of sugar, promote the decomposition and oxidation of glycogen and fat, and regulate serum cholesterol and phospholipid concentration.

6. Promote the absorption and utilization of vitamins (vitamin food): thyroxine can promote the absorption and utilization of niacin, the conversion of carotene into vitamin A and the synthesis of riboflavin, adenine dinucleotide, etc.

7. Promote growth and development: Thyroxine promotes bone development and protein synthesis, and maintains the normal structure of the central nervous system.

Calcium in the human body is mainly found in the form of crystals in bones and teeth. Minerals in our body make up about 5% of our body weight, and calcium makes up about 2% of our body weight. Most of the body's calcium is distributed in bones and teeth, accounting for about 99% of the total, and the remaining 1% is distributed in blood, intercellular fluid and soft tissues.

Factors that affect calcium absorption are:

1) Grains, vegetables and other plant foods contain more oxalic acid, phytic acid, phosphoric acid, which can form insoluble salts with calcium, hindering the absorption of calcium;

2) The uronic acid residues in dietary fiber can be combined with calcium, and the undigested fatty acids and calcium form calcium soap affect the absorption of calcium.

3) Some alkaline drugs, such as soda, berberine, tetracycline, etc., also affect calcium absorption.

Factors that affect calcium absorption in your daily diet.

If the calcium ingested in the daily diet can be well absorbed by the body, then there will not be so many diseases caused by calcium deficiency. It is precisely because of some inadvertent in people's daily diet that the calcium in food is not well absorbed by the body, but is lost in vain. Summarize some of the factors that affect calcium absorption in the diet and let everyone know how to improve calcium absorption.

1) Lactose can promote the absorption of calcium. Because lactose and calcium form a low-molecular-weight soluble complex that promotes calcium absorption, lactose increases the rate at which calcium is absorbed by the small intestine.

2) Vitamin D plays an important role in promoting calcium absorption. The amount of vitamin D in the diet or the body's exposure to sunlight or not will significantly affect the active absorption of calcium. (3) Lysine, arginine, tryptophan, etc. can increase the absorption of calcium, especially lysine has the most obvious effect.

Amino acids can form easily absorbed calcium salts with calcium, so a moderate amount of protein in the diet can increase the rate of calcium absorption from the small intestine, but excessive protein intake will increase urinary calcium excretion.

4) Cellulose, uronic acid, sodium alginate and oxalic acid can reduce calcium absorption. They are found in common foods and can be combined with calcium to form salts that are not easily absorbed. Calcium in oxalic acid-rich foods such as spinach, water spinach, and amaranth is difficult to absorb and affects the absorption of calcium from other foods in the gastrointestinal tract.

5) Excessive fat intake or fat malabsorption can lead to too much free fatty acids in the body, which combine with calcium to form insoluble calcium soap, which is excreted from the feces and reduces calcium absorption.

Studies have shown that there are several factors that affect the body's calcium absorption:

1) Phytic acid (which is abundant in cereals) will affect calcium absorption;

2) If you consume too much fat, the calcium salt formed by fatty acids combined with calcium will affect the absorption of calcium;

3) Some vegetables contain more phytic acid, oxalic acid and very rich fiber, such as bamboo shoots, amaranth, spinach, etc., which will form an adverse factor for calcium absorption. Therefore, it is best not to eat these vegetables when supplementing calcium.

4) The food ingested contains vitamin D, a variety of amino acids, and lactose, which can promote the absorption of calcium.

5) Taking it after or during a meal can improve the absorption rate. Because eating can promote the secretion of gastric juice, it is conducive to the dissolution and dissociation of calcium, and it can delay the emptying of the stomach and improve the absorption rate when entering the food at the same time.

6) Daily doses can be taken in divided doses to improve the absorption rate. If you take a large amount at a time, it exceeds a certain saturation and cannot increase the absorption rate.

7) When there is a lack of calcium in the body, it can improve the absorption rate of calcium in the intestines. If there is no deficiency of calcium in the body, the absorption rate decreases.

The main thing is to check if there is a problem with the duodenum.

1) Vitamin D, certain amino acids and lactose in the diet can form soluble substances with calcium, which is conducive to calcium absorption.

2) On the other hand, phytic acid in cereals, oxalic acid in vegetables, and excessive fatty acids in the body can combine with calcium to form insoluble calcium salts, hindering calcium absorption.

Label: Parenting Questions and Answers There are a few factors in the diet that can promote calcium absorption. Such as:

1.Foods high in potassium and magnesium can affect calcium absorption. 2.

Foods contain too much alkaline phosphate, oxalate (from spinach, etc.), phytic acid (from grains, etc.) and other compounds that can form insoluble compounds with calcium, affecting calcium absorption. 3.Vitamin D promotes the absorption of calcium in the small intestine, so calcium supplementation alone without vitamin D supplementation will not correct the symptoms of calcium deficiency.

4.Amino acids, lactic acid, etc. can promote the dissolution of calcium salts, which is conducive to the absorption of calcium. 5.

Rapid intestinal peristalsis can easily cause diarrhea in infants and young children, which will hinder the absorption of calcium. What factors promote calcium absorption? 1.

Vitamin D regulates the metabolism of calcium and phosphorus and promotes calcium absorption. 2.Lactose has a promoting effect on the absorption of calcium, and it has been proved that eating lactose while eating calcium can greatly improve the absorption of calcium, and the degree of improvement is proportional to the amount of lactose.

It is thought that this is due to the formation of a low-molecular-weight soluble complex between lactose and calcium, which promotes calcium absorption. Therefore, the ** of calcium is better for milk and dairy products, because milk contains lactose. 3.

Adequate protein supply in the diet is also conducive to calcium absorption. Calcium absorption may be due to the formation of soluble calcium salts due to amino acids and calcium released during protein digestion. Animal foods and legumes are rich in protein and calcium, especially in small shrimp skin, kelp, and hair cabbage.

In order to ensure that your body is not deficient in calcium, you should eat more calcium-rich foods that are easy to absorb. In the diet, we should diversify the variety of food, mix meat and vegetables, and avoid calcium deficiency in the body caused by factors such as too little calcium supply or malabsorption.

1. Whether the gastric function is normal: the concentration and quantity of gastric acid secretion affect the absorption of calcium. If the gastric acid secretion is low, the combined form of calcium cannot be converted into ionic form of calcium, and the calcium cannot be fully absorbed.

2. Whether the ratio of calcium and phosphorus is appropriate.

3. The content of vitamin D.

4. The content of phytic acid and oxalic acid in the diet.

5. Whether the protein in the diet is sufficient.

6. Excessive fat intake or fat malabsorption.

7. Exercise, moderate exercise can accelerate the deposition of calcium on bones.

Best foods for calcium** do not include bone broth.

The fat and purines in bone broth are quite high, not only do they not supplement calcium, but they are very meaty. When it comes to calcium supplementation, everyone will think of bone broth, many people think that the highest calcium content is bone broth, but in fact, sesame paste is the most calcium-rich food.

It contains much higher calcium than vegetables, legumes and dairy products, and is rich in vitamins, minerals and amino acids. Regular consumption has a good effect on bone development. In addition, there are milk, soy products, etc., which have a much higher calcium content than bone broth.

Calcium deficiency can lead to a series of problems such as osteoporosis, edema, constipation, cramps, backache, etc., and many people choose to take calcium tablets or calcium-rich foods to achieve the purpose of calcium supplementation.

What are the foods that are rich in calcium

Calcium-rich foods include milk, dairy products, beans, soy products, green leafy vegetables, shrimp skin, black fungus, kelp, seaweed, sea cucumber, sesame paste, etc.
