What appears to decrease the absorption of chromium?Multiple choice question.Vitamin CCalciumPhytic acid

Break Down the Problem

1. Identify factors that influence chromium absorption.
2. Evaluate the options provided in the multiple-choice question regarding their known effects on chromium absorption.

Relevant Concepts

• Chromium is a trace mineral important for insulin function and glucose metabolism.
• Several dietary components can affect the bioavailability of minerals, including chromium.

Analysis and Detail

1. Vitamin C: Usually enhances the absorption of certain minerals like iron but has no significant effect on chromium absorption.
2. Calcium: Some studies suggest that high levels of calcium might interfere with the absorption of chromium, although the effects can be variable.
3. Phytic Acid: Known as an antinutrient found in whole grains and legumes that can bind minerals, thus decreasing their absorption. This is often cited as a significant factor in reducing the bioavailability of chromium.

Verify and Summarize

Considering the known effects of the components, phytic acid is the most recognized for reducing the absorption of chromium.

Final Answer

Phytic acid appears to decrease the absorption of chromium.
