Fat In The Brain Research Paper

(a.) Lipids are the foundation of membranes. They are carbon-containing compounds that are found in organisms and are largely nonpolar and hydrophobic.

Lipids are molecules that contain hydrocarbons and make up the building blocks of the structure and function of living cells. (Dr. Ananya Mandal, MD, 10/09/2012, Para.1) The lipids that are usually in our foods are fats and oils. Lipids are hydrophobic, meaning they have little or no affinity for water. (Neil A. Campbell,

Environment factors, including sedentary lifestyles, high energy intake and social aspects enhance the risk for obesity. A recently published evaluation of the Framingham Study provides an interesting alternative explanation for the worldwide increase in the prevalence of obesity, by demonstrating that the chance of a person to become obese is significantly higher when a friend, sibling or spouse are obese (Christakis and Fowler, 2007). Thus the social net work could be a relevant factor in the obesity epidemic.

The human brain is a feat of evolution: it has allowed humans to have complex thoughts, conscience, build tools, create fires, and much more. Humans did not acquire this simply by chance. Evolution throughout our ancestral past has shaped and moulded the human mind to its state. The earliest of ancestors, including apes, had very small brains, but as evolution progressed, so too did the human brain. The rapid progression of human intelligence has been attributed to environmental changes causing humans to change with their surroundings for survival. This lead to the expansion of specific areas of the brain, vastly differing maturation of humans compared to our

Introduction: Cell membranes contain many different types of molecules which have different roles in the overall structure of the membrane. Phospholipids form a bilayer, which is the basic structure of the membrane. Their non-polar tails form a barrier to most water soluble substances. Membrane proteins serves as channels for transport of metabolites, some act as enzymes or carriers, while some are receptors. Lastly carbohydrate molecules of the membrane are relatively short-chain polysaccharides, which has multiple functions, for example, cell-cell recognition and acting as receptor sites for chemical signals.

The purpose of this essay is to examine the article " The Fat-Brain Axis Enters a New Dimension," by Joel Elmquist and Jeffery Flier. This essay will attempt to explain this article and summarize its key points.

The more general research question under review is about obesity. My researchable question is the effects of obesity on health, what health concerns can happen due to obesity. It can be easily found and discussed the potential dangers of obesity. People should care more about this topic because people need to care about their health. Obesity is lowering our expected years to live which it should be doing the opposite because of all the healthcare and medicine we have now. It is prevalent in the younger population which is different than it has been in the past. This is a problem that could potentially affect anyone or anyone you know, that is why people should care about this topic, it is a problem.

Due to being on a high fat, high-calorie diet because of my Cystic FIbrosis gaining weight has been a hightlight in my life, to help me achieve this goal of gaining weight my dad bet me that if I gained ten pounds in one appointment he would give me one hundred dollars. Seven years after making that bet I hopped on the scale at the Children's Hospital and as the numbers ticked on I knew this would be the day, this would be the appointment then there was a screeched. As the doctor came in automatically I screamed so excitedly, "I gained ten pounds! I finally beat the ten pounds! Ha!" Knowing this would be the day and indeed, it finally was. As I talked to my dietician I truly had the realization that I achieved my life long health goal, I achieved

The process of becoming obese will affect and change the brain chemistry of the brain and people could be born with predisposition in becoming obese. We all consume food and take pleasure in eating them, especially sugar, however eating excess of them cause changes. Our brain is triggered in producing dopamine when consuming sugar, dopamine is a neurotransmitter that brings pleasure feeling, and our brain associates it as a reward, becoming a habit (Rabin, 2015). As people consume more and becoming obese, the higher association of pleasure feeling from dopamine when eating creates a behavior pattern of overeating, which would be very difficult to break (Harmon, 2010). This is changing the brains chemistry by creating a neurochemical dependency

In order to experience the best quality of life possible, you've got to become intentional about how you live your life. It's one thing to just go through life hoping that everything will work out. It's another thing to set things up to facilitate the best life possible. While there are factors you can't control, there are a lot of things that are within your control. For example, you may not be able to forsee a genetic thread that leads you to experience brain cancer, however you can live a lifestyle that is conducive to optimal brain health. There are a few factors to consider when it comes to brain health. Consider these four.

Since I have had many health issue I have truly focused my mind to my health. When I came across this article of the updates of the dietary guidelines of this year it caught my attention. This article educates people of the fats we intake in our daily life’s saturated fats vs. polyunsaturated fats which was interesting to know about the fats that put people at risk for heart disease and the “good” fats. This article is a good read for the population that trying to watch their diet and stay health and fit. Not knowing much about the Author Carrina Storrs it was surprising to read she had a PhD in addition to being a freelance health and science journalist. Storrs quotes Barbara Millen, chair

In the instance of obesity, we know that there are various causes, and therefore, there must be various solutions. Though some causes may be because of a medical conditions which disqualify the patients from easily losing weight, the most common cause for obesity is simply that a person eats more than what their body can burn off. The result is that excess energy that is not used is stored in the body, or more commonly known as fat. The most practical approach is to create a drug that intervenes with the body’s natural processing functions. If we could create a prescription that forced the body to survive off of its existing energy storages instead of adding more reserves to them, then a cure for obesity would be both possible and probable. Unfortunately, this thought is much too advanced for our primitive society, or is it? Back in 2009, when researchers were searching for a cure for cancer, they discovered a compound that when injected into mice caused an extreme reduction in appetite as well as up to thirty percent weight loss. This compound would trick the brain into thinking that it was not hungry (“Obesity Drugs Might” 2). This compound may be extremely useful on the path to a cure, but it is not the only one.

Cholesterol is present in every cell of the body, predominantly in the cell membrane but also in other organelles such as the membranes of the mitochondria and the endoplasmic reticula. As a component of the cell membrane it aids the maintenance of cell integrity and plays a part in cell to cell communication which enables human functionality. The plasma membrane is composed of a phospholipid bilayer, as the name suggests, phospholipids are lipids attached to a phosphate group and they consist of a head that is hydrophilic and therefore polar, and a tail that is hydrophobic and non-polar.

The neocortex first appeared in primates and is most developed in humans. These developed hemispheres are thought to be responsible for the development of language, abstract thought, and consciousness. The neocortex has almost limitless learning abilities. However, the reptilian, limbic, and neocortex do not operate independently. They have many connections with one another.

The ability of speech and language processing has always been a defining factor in what makes humans unique, especially from their closest living relative primates. This paper will analyze the differences in modern human brain structure and the common chimpanzee brain structure (pan troglodytes) in regards to the language and speech function. Language and speech processing in modern humans will focus on two parts of the cerebral cortex: Broca’s area and Wernicke’s area, which is responsible for generating speech and language and receiving speech and language respectively. Broca’s area will be analyzed by the two parts it is made up of: Brodmann area 44, associated mainly with phonological tasks and Brodmann area 45, associated mainly with semantic processing. Wernicke’s area receives and interprets speech and language and is shown to be connected to Broca’s area by a neuronal tract known as the arcuate fasciculus. The structure of the common chimpanzee brain is shown to have homologous structures to Broca’s and Wernicke’s area in modern humans, but is significantly smaller, and is unable to perform the same developed functions as modern humans in regards to language and speech, but is much more limited and simplified.
