Toxicology expert Zhao Mingwei explained that drinking pork ribs soup with a little vinegar can promote the release of calcium in the bones, which is beneficial to the body's absorption. But many mothers only know that smashing the big bones and then boiling the soup can release more calcium, but also beat the heavy metals accumulated in the bones, and the amount of calcium supplemented is also very limited. 25 bowls of big bones Soup is equal to the calcium of 1 cup of milk.
Are heavy metals in bone broth dangerous? Zhao Mingwei said that the lead in bones will exist in the form of "lead phosphate", which is not easy to dissolve. The lead content does not affect the dissolution rate. Bones with a lot of lead and bones with less lead have the same dissolution rate in the soup. The clearer data in a paper is that each kilogram of bone broth has a lead content of 0.002 mg after being stewed with vinegar.
According to the US Environmental Protection Agency (EPA), the Tolerable Daily Intake (TDI) of lead is 0.0036mg/kg/day. There is no risk of being poisoned. Converted to a 60-kilogram adult, the allowable daily intake of lead is 0.216mg, and there will be no problem in a lifetime.question.
If you calculate the lead content of 0.002 mg per kilogram of bone broth, you must drink at least 180 kilograms of bone broth every day to reach this figure, which is equivalent to drinking 540 bowls of soup per bowl. The daily intake of bone broth for the average adult is much lower than this figure, so there is no need to worry too much about the lead in drinking bone broth, which may have immediate health risks.
Zhao Mingwei emphasized that it is very important to make risk assessment suggestions on whether food is safe or not. It is very important to find out the safe value of ingestion through repeated verification through scientific experiments, especially to calculate the "dose". However, how to eat the most comfortable food depends on each person's choice. If you think that big bone broth will dissolve lead, it is not safe, you can choose to use other parts of meat to make soup, or even use vegetable soup base.
In addition, it is now popular to pick up the bones of the soup base to smoke, so some people will ask, "Will you eat lead if you eat the bone marrow of the big bone soup?" Zhao Mingwei said that the answer is "yes", but a Tolerable throughout the day, you need to eat more than 750 grams of bone marrow per day to eat excess lead. Therefore, it is okay to suck bone marrow occasionally, but if you want to drink bone marrow as a hand shaker every day and drink a lot, excessive intake will inevitably increase health risks.
For calcium supplementation, Zhao Mingwei suggested that according to the recommended daily intake of nutritious diet for Chinese people, those over the age of 19 should consume 1000 mg of calcium per day to prevent bone loss. Calcium supplementation from the diet is the best way. Milk is the most convenient source of calcium.A cup of 240cc milk has about 250 mg of calcium, which is equivalent to "how much you drink to make up for it", but you can't drink milk as boiling water. It is recommended to drink 1 to 2 cups of milk, long-lasting milk or tofu (plant-based) a day, and then supplement from food such as larvae, dried small fish, black sesame, processed soy products, etc., to obtain the daily calcium required. .
However, Zhao Mingwei also reminded that although cheese slices are rich in calcium, calcium and calories are also different with the different manufacturing sources of each batch. It is not recommended as the main source of fixed calcium supplementation .
