All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study was conducted to assess the effect of nutrition education utilizing computerized dietary analysis on nutrition knowledge, dietary compliance, nutrition status, and quality of life in hemodialysis patients. Twenty patients of the Bonneville Dialysis Center in Ogden, Utah voluntarily agreed to participate in this six-month study. All participants completed quality of life assessments, the Beck Depression Inventory© (BDI), and a nutrition knowledge assessment pre- and post-study. Patients in the treatment group (n=12) completed monthly 3-day food records which were analyzed by Computrition® nutrient analysis software. Results were discussed with the patients during one-on-one education sessions. Control patients (n=8) completed …

The effect of reducing the phytate in soy-protein isolates on nonheme-iron absorption was examined in 32 human subjects. Iron absorption was measured by using an extrinsic radioiron label in liquid-formula meals containing hydrolyzed corn starch, corn oil, and either egg white or one of a series ofsoy-protein isolates with different phytate contents. Iron absorption increased four- to fivefold when phytic acid was reduced from its native amount of 49-8.4 to < 0.01 mg/g of isolate. Even relatively small quantities of residual phytate were strongly inhibitory and phytic acid had to be reduced to < 0.3 mg/g of isolate (corresponding to < 10 mg phytic acid/meal) before a meaningful increase in iron absorption was observed. However, even after removal ofvirtually all the phytic acid, iron absorption from the soy-protein meal was still only half that of the egg white control. It is concluded that phytic acid is a major inhibitory factor of iron absorption in soy-protein isolates but that other factors contribute to the poor bioavailability of iron from these products.
