Can portion size and energy density estimates be influenced by perceived “healthiness” of foods?

Sensitivity to portion size of unhealthy foods

One portion size of foods frequently consumed by Korean adults

This study aimed to define a one portion size of food items frequently consumed for convenient use by Koreans in food selection, diet planning, and nutritional evaluation. We analyzed using the original data on 5,436 persons (60.87%) aged 20 ~ 64 years among 8,930 persons to whom NHANES 2005 and selected food items consumed by the intake frequency of 30 or higher among the 500 most frequently c...

Combined effects of energy density and portion size on energy intake in women.

BACKGROUND Increases in both the portion size and energy density of food have both been shown to increase energy intake, but the combined effects of such increases have not been investigated. OBJECTIVE The objective was to determine the combined effects of energy density and portion size on energy intake in women. DESIGN This study used a within-subjects design. Once a week for 6 wk, 39 wom...

The influence of food portion size and energy density on energy intake: implications for weight management.

The increase in the prevalence of obesity has coincided with an increase in portion sizes of foods both inside and outside the home, suggesting that larger portions may play a role in the obesity epidemic. Although it will be difficult to establish a causal relationship between increasing portion size and obesity, data indicate that portion size does influence energy intake. Several well-contro...

Assessment of satiety depends on the energy density and portion size of the test meal

OBJECTIVE Foods that enhance satiety can reduce overconsumption, but the availability of large portions of energy-dense foods may counter their benefits. The influence on meal energy intake of varying the energy density and portion size of food consumed after a preload shown to promote satiety was tested. DESIGN AND METHODS In a crossover design, 46 women were served lunch on six days. On fou...
