Wholemeal bread and satiety

Area of Science:

• Nutrition Science
• Dietary Studies

Background:

• Dietary fiber intake is influenced by bread type.
• Previous studies suggest wholemeal bread may alter nutrient consumption patterns.

Purpose of the Study:

• To investigate the impact of white versus wholemeal bread on nutrient intake.
• To determine if bread type affects meal composition and subsequent 24-hour nutrient consumption.

Main Methods:

• Ten healthy volunteers participated in a controlled feeding study.
• Participants consumed unlimited bread (white or wholemeal), butter, and jam over four sessions.
• Nutrient intake was assessed during the meal and for 24 hours post-meal.

Main Results:

• No significant differences were observed in the quantity or type of nutrient intake.
• Both white (70% extraction) and wholemeal (100% extraction) bread did not significantly alter nutrient consumption.
• Findings contradict previous reports on bread type and nutrient intake.

Conclusions:

• The type of bread consumed (white vs. wholemeal) does not significantly impact nutrient intake in normal volunteers.
• Dietary choices beyond bread type may be more influential on overall nutrient consumption.
• Further research is needed to explore factors influencing nutrient intake beyond bread composition.
