Fe-ueling Iron Absorption

CSEF · 2019 Chemistry

Taryn E. Manns · Sing Lum Elementary, Bakersfield, Kern County

Overview

Objectives The objective of my experiment is to determine if iron absorbs faster on an empty stomach or a full stomach. Methods Iron detector tablets, iron color chart, test tubes, distilled water, white distilled vinegar, almond flour. Measured the rate of absorption of iron in solutions representing a full stomach and an empty stomach. Results The rate of absorption of iron was significantly faster for the solution representing an empty stomach than the solution representing a full stomach. The solution representing an empty stomach also reached a higher level of absorption on the color chart reaching 5ppm (parts per million). The solution representing a full stomach only reached 1 ppm on the iron color chart. Conclusions Based on my experiment, iron absorption occurs faster on an empty stomach. This information is important for people who take iron supplements.

Summary statement

I showed that iron absorption occurs faster on an empty stomach.

Help received

I prepared all of the solutions and compared the solutions to the color chart by myself. I had help with the timing at the beginning of each trial from my mom.
