In 20 12 years in China, the average salt intake of adults was10.5g, far exceeding the recommended amount. Excessive salt intake is very harmful, except for hypertension; Studies have shown that obesity and osteoporosis are not good for the kidneys.
6 grams of salt, it's easy to say. But how much is 6 grams of salt? How to control it at ordinary times?
How much is 6 grams of salt? Everyone says 6 grams of salt, but how much is 6 grams of salt? This is very abstract. Is there a more vivid description?
I have seen a netizen do a good job before, and directly put the salt on the balance to weigh it. According to the netizen's conclusion, 6 grams of salt is equivalent to as much as a beer bottle cap, and it is flat.
Besides, there is actually a simpler way. That is to buy a quantitative salt spoon, which is specially produced to help control salt. I searched a treasure and found a small spoon with 2 grams of salt, which I think is very good.
How many grams of salt is usually put in a dish? In fact, it is impossible to control salt so accurately. Anyone who has studied chemistry knows that the main component of salt is sodium chloride (NaCl). If you eat too much salt, the main sodium ion that is harmful to human body is too much. Therefore, controlling salt is precisely controlling sodium.
How much sodium is there in 6 grams of salt? This still requires chemical knowledge.
The relative atomic mass of sodium is 23 and that of chlorine is 35.5. Then that molecular weight of sodium chloride is 58.5. 6 grams of salt (sodium chloride) contains sodium salt =6×(23÷58.5)≈2.4 grams.
In other words, the daily sodium intake should be controlled within 2.4 grams.
Then, if a person cooks three dishes a day, is it enough to put 2 grams of salt in each dish?
Actually, it's not like this. Because, in addition to sodium contained in salt, monosodium glutamate and soy sauce all contain sodium salt.
If you put 2 grams of salt and add some monosodium glutamate, it will definitely exceed the sodium content of 2 grams of salt. In addition, in addition to salt and condiments, there are other foods containing sodium salt, which makes you hard to prevent.
Not to mention the most common pickles, pickles, ham and salted fish. They are very salty when eaten, and a lot of salt must be added.
There are some unexpected foods with high sodium content, such as toast bread, soda crackers, sausages, some canned foods, and some snacks such as melon seeds, preserved plum, potato chips and instant noodles. There are also some sports drinks that also contain sodium.
Even more unexpected is that natural foods also contain sodium, such as Chinese cabbage, chrysanthemum, mustard, spinach and water spinach.
All of the above shows that it is difficult to control the intake of sodium salt accurately. Because the sodium salt in some foods is hard to prevent. Maybe if you are not careful, your daily sodium intake will exceed the standard.
What can be done to control salt as accurately as possible? In fact, there is no good way. Here are some suggestions for your reference.
1, use a quantitative salt spoon
Use a salt spoon, although there is no guarantee that the daily sodium intake will not exceed the standard. At least you can ensure that the intake of salt is more accurate. For example, 1 person has three meals a day and cooks three dishes. If monosodium glutamate and soy sauce are added to cooking, then the salt should be less than 2 grams.
2. Develop the habit of eating lightly
Put less soy sauce and monosodium glutamate in cooking. Eat less processed foods such as pickles, pickles and ham.
3. Compare the sodium content of shopping food.
For example, if you go to the supermarket to buy dried noodles, you can look at the nutrient composition table on the packaging bag, compare the sodium content, and choose foods with less sodium and salt.
Summary: In a word, it is difficult to control sodium salt accurately. However, the tastes of China people are generally heavy, so there is still a lot of room for decline as long as we pay a little attention.
