dc.description.abstractPECTINS ARE A TYPE OF SOLUBLE FIBER PRESENT IN NATURAL AND PROCESSED FOODS. EVIDENCE REGARDING THE EFFECT OF ESTERIFICATION DEGREE OF PECTINS ON IRON ABSORPTION IN HUMANS IS SCARCE. IN THE PRESENT STUDY, THE EFFECT OF PECTINS WITH DIFFERENT DEGREES OF ESTERIFICATION ON NON-HEME IRON ABSORPTION IN WOMEN WAS EVALUATED. A CONTROLLED EXPERIMENTAL STUDY WAS CONDUCTED WITH BLOCK DESIGN, INVOLVING 13 APPARENTLY HEALTHY, ADULT WOMEN. EACH SUBJECT RECEIVED 5 MG FE (FESO4) WITHOUT PECTIN (CONTROL) OR ACCOMPANIED BY 5 G CITRUS PECTIN, TWO WITH A LOW DEGREE OF ESTERIFICATION (27 AND 36%), AND ONE WITH A HIGH DEGREE OF ESTERIFICATION (67 TO 73%), EACH ON DIFFERENT DAYS. EACH DAY, THE 5 MG FE DOSES WERE MARKED WITH RADIOACTIVE FE-59 OR FE-55. RADIOACTIVITY INCORPORATED INTO ERYTHROCYTES WAS DETERMINED IN BLOOD SAMPLES 14 DAYS AFTER THE MARKED FE DOSES WERE CONSUMED. ON DAYS 18 AND 36 OF STUDY, 30 AND 20 ML BLOOD SAMPLES WERE OBTAINED, RESPECTIVELY, AND BLOOD SAMPLE RADIOACTIVITY INCORPORATED INTO ERYTHROCYTES WAS DETERMINED. BODY IRON STATUS WAS DETERMINED FROM BLOOD TAKEN ON DAY 18. WHOLE BODY BLOOD VOLUME WAS ESTIMATED FOR CALCULATE IRON BIOAVAILABILITY; IT WAS ASSUMED THAT 80% OF ABSORBED RADIOACTIVITY WAS INCORPORATED INTO THE HB. ALL WOMEN PARTICIPANTS SIGNED AN INFORMED CONSENT OF PARTICIPATION AT BASELINE. IRON BIOAVAILABILITY (MEAN GEOMETRIC +/- 1 SD) ALONE (CONTROL) WAS 18.2% (12.3-27.1%), IRON + PECTIN27 WAS 17.2% (10.2-29.2%), IRON + PECTIN36 WAS 15.3% (9.5-24.6%), AND IRON + PECTIN67 WAS 19.5% (10.0-38.0%). NO STATISTICALLY SIGNIFICANT DIFFERENCES BETWEEN IRON BIOAVAILABILITY (REPEATED MEASURES ANOVA, P = 0.22) WERE OBSERVED. PECTIN ESTERIFICATION DEGREE DOES NOT INFLUENCE THE BIOAVAILABILITY OF NON-HEME IRON IN WOMEN.
