1. Coffee: Coffee contains high levels of caffeine, which increases calcium excretion in urine and hinders calcium absorption in the intestines.
2. High-salt foods: Excessive salt intake burdens the kidneys, causing calcium and potassium to be taken away from the body. This can lead to long-term calcium deficiency and osteoporosis.
3. Alcohol: Alcohol disrupts bone cell metabolism and impairs calcium absorption, increasing the risk of osteoporosis.
4. High-fat foods: Fatty foods delay calcium absorption by binding with it in the intestines, forming insoluble compounds.
