High-fat Diet Contributes to
Aggressive Behavior
Hypothesis:
High-fat diet contributes to aggressive behavior.
Introduction:
Aggression is a behavior that is destructive, hostile or violent and is intended cause harm, injury or damaged to the target person or object. Aggression and violence are the major problems in our society and one of the main contributions of this behavior is socioeconomic status (SES). According to the American Psychological association (APA), socioeconomic status is often measured as a combination of education, income and occupation, which classified individuals into different social standing. As proven by several empirical studies, lower SES put individuals to more risk of aggression ADDIN EN.CITE <EndNote><Cite><Author>Anderson</Author><Year>2002</Year><RecNum>7</RecNum><DisplayText>(1)</DisplayText><record><rec-number>7</rec-number><foreign-keys><key app="EN" db-id="xzr20pz9avff54epwp2v0f00x299advs0sd2">7</key></foreign-keys><ref-type name="Journal Article">17</ref-type><contributors><authors><author>Anderson, A.C., Bushman, B.</author></authors></contributors><titles><title>HUMAN AGGRESSION</title><secondary-title>Annu.

However, apart from socioeconomic factor, biological factor such as diet is another potential source that helps in explaining aggressive behavior. Diet could alter our hormones, the chemicals that are carried along blood stream or body fluid to the target cells to produce specific physiological response. These hormonal secretions are altered; it eventually leads to alteration in bodily responses. This paper will discuss about high fat-diet and aggression by focusing on saturated fat and Trans fat (or bad fat) that are mostly found in meat, daily product, crisp, cookies etc. Bad fat is known to raise LDL (bad) cholesterols and lower HDL (good) cholesterol, which are the precursor for the biosynthesis of steroid hormones such as estrogen or estradiol (E2) and corticosterone. When the levels of these hormones circulation are elevated, it implies that aggressive behavior will also be elevated. Fat high in diet would result in the accumulation of adipose tissue or fat droplets in the body, which act as enzyme aromatase, converting testosterone to estrogens (estradiol). This in turn activates the brain circuit that control male territorial behavior. The neuroendocrine mechanism is known to affect aggressiveness in rodents ADDIN EN.CITE <EndNote><Cite><Author>Franscisco</Author><Year>2009</Year><RecNum>1</RecNum><DisplayText>(2)</DisplayText><record><rec-number>1</rec-number><foreign-keys><key app="EN" db-id="xzr20pz9avff54epwp2v0f00x299advs0sd2">1</key></foreign-keys><ref-type name="Web Page">12</ref-type><contributors><authors><author>University of California San Franscisco</author></authors></contributors><titles><title>Estrogen Link In Male Aggression Sheds New Light On Sex-specific Behaviors</title></titles><dates><year>2009</year></dates><urls><related-urls><url>http://www.sciencedaily.com/releases/2009/10/091001163724.htm</url></related-urls></urls></record></Cite></EndNote>(2).
