INTRODUCTION This study examined differences in food preferences and dietary intake among male and female Filipino adolescents of different nutritional status as measured by body mass index (BMI). METHODS One hundred and twenty 13-17-year olds from various schools and communities in Metro Manila, The Philippines were selected through quota sampling with BMI, sex and age as criteria. Data on m...

Obesity is an increasing problem and identification of the driving forces for overeating of energy-rich food is important. Previous studies show that the stress and sex steroid allopregnanolone has a hyperphagic effect on both bland food and palatable food. If allopregnanolone induces a preference for more palatable or for more energy-rich food is not known. The aim of this study was to elucida...

Identification of reinforcers for individuals with developmental disabilities is often based on the outcome of preference assessments in which participants make selections from among a variety of items. We determined the extent to which individuals might show a general preference for food items over leisure items during such assessments and whether leisure items that are "displaced" by food ite...

Dietary behaviour can modify the risks for coronary heart disease (CHD). Dietary fat contributes to the sensory characteristics of many foods, but there are individual differences in liking for regular and reduced fat products. Preference for dietary fat might differ between healthy individuals and those of diagnosed CHD status. Preference for full-fat versus low-fat foods was assessed in a gro...

The present study was carried out to examine 6 plants including aquatic and terrestrial plants on food preference and growth of grass carp. 7 experimental treatments with three replicates were considered. The experimental treatments were ponds containing T1: M. spicatum, T2: C. demersum, T3: A. filiculoides, T4: L. minor, T5: C. dactylon, T6: M. sativa and T7: M. Spicatum + C. demersum + A. fil...

Obese (n = 20) and normal weight (n = 20) children (8-11 years) were compared using the delay of gratification paradigm. All children were asked to choose between an immediate reward or a larger delayed (one day) reward. Half the children were offered an edible incentive and half a non-edible incentive. Results showed that the obese choose immediate rewards more often than normals only when the...

The social transmission of food preferences (STFP) is a behavioural task of olfactory memory, in which an observer rat learns safe food odours from a demonstrator rat, and shows preference for this odour in a subsequent choice test. However, previous studies have failed to detect the transmission of information about food of potential danger and food aversion using STFP test. In this study, we ...

Snack food like potato chips substantially contributes to energy intake in humans. In contrast to basic food, snacks are consumed additionally to other meals and may thereby lead to non-homeostatic energy intake. Snack food is also frequently associated with hedonic hyperphagia, a food intake independent from hunger. Analysis of brain activity patterns by manganese-enhanced MRI has previously r...

The social transmission of food preference task (STFP) is based on the principle that dietary information can be communicated between rodents during social interaction (Galef and Kennett, 1987). Briefly, a demonstrator mouse consumes a novel flavor, and then freely interacts with an observer mouse. The observer mouse is now " socially cued " toward that flavor, and will prefer it in a choice pa...
