How would it look to apply the principles of Maslow’s Hierarchy of Needs to food management? Why even wrestle with such a conundrum? The Satter Eating Competence Model (ecSatter) stresses joining with individuals right where they are and working within their constraints and circumstances. Rather than emphasizing food selection and portion sizes, ecSatter operationalizes the Dietary Guidelines b...

The harvest media from five strains of Pseudomonas aeruginosa collected from severe clinical infections did not contain a collagenase. Instead, an enzyme was isolated that could degrade the ground substance of the cornea. Partial purification of this enzyme indicated that it was the only enzyme in the harvest media that cotdd destroy the rabbit cornea after intralamellar injection. Na2EDTA comp...

As the sizes of food packages and portions have changed rapidly over the past decades, it has become crucial to understand how consumers perceive and respond to changes in size. Existing evidence suggests that consumers make errors when visually estimating package and portion sizes, and these errors significantly influence subsequent food choices and intake. We outline four visual biases (arisi...

Normative eating cues (portion size, social factors) have a powerful impact on people's food intake, but people often fail to acknowledge the influence of these cues, instead explaining their food intake in terms of internal (hunger) or sensory (taste) cues. This study examined whether the same biases apply when making predictions about how much food a person would eat. Participants (n = 364) r...

A number of methods have been developed to assist subjects in providing an estimate of portion size but their application in improving portion size estimation by children has not been investigated systematically. The aim was to develop portion size assessment tools for use with children and to assess the accuracy of children's estimates of portion size using the tools. The tools were food photo...

Duodenal function was studied in 11 healthy volunteers after intragastric instillation of a mixed semi-elemental meal. The duodenum accepted chyme of varying pH, osmolality, and nutrient concentration; and, as a result of biliary, pancreatic, and enteric secretion as well as absorption, it delivered chyme with nearly constant pH, osmolality, and nutrient concentration to the jejunum. The flow r...

What determines whether a person perceives an eating occasion as a meal or snack? The answer may influence what and how much they eat on that occasion and over the remainder of the day. A survey of 122 participants indicated that they used food cues (such as the food quality, portion size, perceived healthfulness, and preparation time) as well as environmental cues (such as the presence of frie...
