Which ingredient found in coffee and cola can decrease calcium absorption?

The ingredient found in both coffee and cola that can decrease calcium absorption is phosphoric acid.

Here's why:

* Phosphoric acid is a common ingredient in both beverages. It's used for its tart flavor and to help preserve the drinks.

* Calcium and phosphorus compete for absorption in the intestines. When there's a high amount of phosphorus present, it can hinder the body's ability to absorb calcium. This is because the body prioritizes absorbing phosphorus for vital functions like bone formation and energy production.

Important Notes:

* The effect of phosphoric acid on calcium absorption is relatively small and likely not a significant concern for most people who consume these beverages in moderation.

* Other factors, like diet and overall health, also play a role in calcium absorption.

* It's always a good idea to consult with a healthcare professional for personalized advice about your diet and calcium intake.
