Anorexia Nervosa01:28

Anorexia Nervosa

90
Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.

Regulation of Food Intake01:30

Regulation of Food Intake

247
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...

Confirmation Biases01:31

Confirmation Biases

5.5K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

Primary Motives: Hunger and Thirst

210
Hunger and thirst are fundamental physiological drives crucial for maintaining homeostasis and ensuring the survival of both humans and animals. These drives are regulated through complex interactions between the brain, hormones, and sensory receptors.
Hunger arises when the brain detects changes in the body's nutrient levels, including glucose, lipids, amino acids, and hormones such as ghrelin and leptin. The hypothalamus plays a central role in hunger regulation. The lateral hypothalamus...

Bulimia Nervosa01:30

Bulimia Nervosa

104
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Binge Eating Disorders01:23

Binge Eating Disorders

88
Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

Area of Science:

  • Public Health
  • Nutrition Science
  • Pediatrics

Background:

  • Malnutrition, encompassing undernutrition and obesity, significantly impacts children due to micronutrient deficiencies.
  • Hidden hunger, characterized by insidious micronutrient deficits, poses a major public health challenge.

Purpose of the Study:

  • To review inadequate food consumption, food security, and nutritional inadequacy leading to hidden hunger.
  • To highlight prevention and treatment strategies for key micronutrient deficiencies in Brazil.

Main Methods:

  • Bibliographic review of PubMed, Lilacs, and SciELO databases.
  • Search terms included 'hidden hunger' and 'child' in articles from 2013-2023.
  • Analysis of national and international studies on micronutrient deficiencies.

Main Results:

  • Micronutrient deficiencies can occur without obvious symptoms, termed hidden hunger.
  • Strategies include promoting healthy eating and routine supplementation of iron, vitamin D, and vitamin A.
  • Key deficiencies in Brazil (iron, vitamin A, vitamin D, zinc) were examined for diagnosis, prevention, and treatment.

Conclusions:

  • Addressing zero hunger and zero obesity requires unified policies and nutritional education programs.
  • Integrated approaches are essential for combating malnutrition and its underlying causes in children.
