People who drink vinegar in moderation will not increase the risk of osteoporosis and also promote the absorption of calcium are those who are suitable to eat vinegar. If in fasting state or patients with duodenal ulcer and gastric ulcer, it is recommended not to aggravate the burden of gastrointestinal. The vinegar that people drink will be transformed into other substances in human body through oral cavity and digestion by stomach, and then absorbed through intestine, and it will not act directly on human bones and will not lead to osteoporosis. When the human stomach acid secretion is not enough, vinegar can help to turn the insoluble calcium in food into soluble calcium ion and combine it into calcium acetate which is both soluble in water and easily absorbed by human body, so it can greatly promote the absorption of calcium in human body. There is also aged vinegar which contains not only acetic acid but also more calcium and B vitamins and other trace elements. Moderate consumption of vinegar not only will not increase the risk of osteoporosis, but also can prevent osteoporosis.
