Optimal Foraging00:48

Optimal Foraging

14.1K
How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

Dietary Connections

62.8K
In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and the citric acid cycle—tie into those that break down other organic compounds. As a result, various foods—from apples to cheese to guacamole—end up as ATP. In addition to carbohydrates, food also contains proteins and lipids—such as cholesterol and fats. All of these organic compounds are used...

Conditioned Taste Aversion01:14

Conditioned Taste Aversion

1.2K
Conditioned taste aversion, also known as sauce béarnaise syndrome, is a phenomenon in which an individual develops an aversion to a certain food taste following a negative experience, typically illness. This form of aversion is a type of classical conditioning in which the taste of the food (conditioned stimulus, CS) is associated with the experience of illness (unconditioned stimulus, UCS).
A notable characteristic of conditioned taste aversion is that it often requires only a single...

Regulation of Food Intake01:30

Regulation of Food Intake

3.0K
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Taste Buds and Receptors01:20

Taste Buds and Receptors

5.5K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Cephalic Phase of Digestion01:24

Cephalic Phase of Digestion

4.3K
The process of digestion is composed of three stages – cephalic, gastric, and intestinal – each with a distinct control center. The cephalic phase is the first stage, and it starts even before the food enters the stomach. It is controlled by the central nervous system and is initiated by any food-related sensory stimuli, such as the sight and smell of food, which send signals to the brain. While eating, the taste receptors intensify these signals, which travel to the cerebral cortex...

Area of Science:

  • Computer Vision
  • Nutrition Informatics
  • Artificial Intelligence

Background:

  • Dietary assessment systems often rely on manual logging, which can be burdensome.
  • Automated food recognition from images is challenging due to visual variations and similar appearances of different foods.

Purpose of the Study:

  • To improve the accuracy of food recognition in dietary assessment systems.
  • To reduce ambiguity in food image analysis by incorporating contextual dietary information.

Main Methods:

  • Developed a dietary assessment system utilizing food images for intake recording.
  • Incorporated food co-occurrence patterns and personalized learning models into image analysis.
  • Evaluated the model on 1453 food images from 45 participants under natural eating conditions.

Main Results:

  • The proposed model demonstrated improved food recognition accuracy.
  • Incorporating contextual dietary information led to an approximate 10% increase in food categorization accuracy.

Conclusions:

  • Contextual dietary information, including co-occurrence patterns and personalized models, significantly enhances food image recognition.
  • This approach offers a promising solution for more accurate automated dietary assessment.
