What effect does caffeine have on calcium absorption?

• A. It improves calcium absorption
• B. It has no impact on calcium absorption
• C. It negatively affects calcium absorption
• D. It stimulates calcium production

Answer: (C)

Caffeine negatively affects calcium absorption. Research indicates that the consumption of caffeine can lead to a decrease in calcium retention in the body. This occurs primarily because caffeine increases urinary calcium excretion, which means that with higher caffeine intake, the body is losing more calcium than it can absorb. This relationship is particularly critical for individuals at risk of osteoporosis or those who need to maintain adequate calcium levels for bone health.

The understanding of caffeine’s impact is vital for individuals who consume it frequently, as they may need to consider their overall calcium intake to mitigate any potential negative effects on bone density. Overall, recognizing caffeine's role in calcium absorption helps in making informed dietary choices, especially for maintaining bone health.
