Summary
Mice prefer vegetable oils, similar to palatable sucrose solutions. This preference for vegetable oils was not altered by chronic corn oil intake, though both diets increased body weight.
Area of Science:
- Nutrition Science
- Animal Behavior
- Sensory Science
Background:
- Dietary fat and sugar intake significantly impact food preferences and body weight.
- Understanding the palatability of vegetable oils is crucial for dietary research.
Purpose of the Study:
- To evaluate mouse preference for different vegetable oils.
- To compare vegetable oil preference with sucrose preference.
- To investigate the effects of chronic intake on preferences.
Main Methods:
- Two-bottle choice test used to assess preference in mice.
- Tested various vegetable oils (corn, canola, mixed) and sucrose solutions.
- Analyzed preference changes after chronic dietary interventions.
Main Results:
- Mice preferred all tested vegetable oils (1%) and sucrose solutions (5-20%) over a control.
- 1% corn oil preference was comparable to sucrose solutions.
- Oil-sucrose mixtures were preferred over individual components.
- Chronic 20% sucrose intake altered preference, while 100% corn oil did not.
- Both chronic diets led to significant body weight increases.
Conclusions:
- Mice exhibit a strong preference for vegetable oils, rivaling that of sucrose.
- Vegetable oil preference is not diminished by chronic corn oil consumption.
- Dietary fats and sugars influence body weight gain.
