Discuss two or more ways in which eating and satiation are cont\rolled by neural mechanisms One way which eating and satiation are controlled by neural mechanisms is through the Set point theory and Homeostasis – the maintenance of a constant internal environment. KEELEY (1986) proposed that we have a biologically determined standard around which our body weight (specific fat mass) is regulated, hence if we eat too much or too little; homeostatic mechanisms accordingly return us to our original weight. However, PASSER ET AL (2009) found persistent overeating or under eating may make it increasingly more difficulty for homeostatic mechiasms to do this and over time may settle a new weight. Homeostasis controls a dual-feeding system, which when blood the glucose increases the ventromedial hypothalamus is activated, giving you the feeling of being full. When blood glucose decreases the Lateral hypothalamus is activated, giving you the feeling of hunger.
The person may want to keep a food diary to help discover which foods make their condition worse and avoid them in the future.

I support the part of my hypothesis where I state that living things prefer fresh products to consume over stale or dead products by observing how humans eat and common knowledge. The part where I think pill bugs would have the same mindset is not supported, so I would need further investigation on that. The data from experiment 2 shows that pill bugs have slow reaction times. It takes them a while to actually feel threatened to being injured/armed. The data from experiment 3 shows that the pill bugs preferred the dead leaves over the fresh leaves over time.
1. What is nutrition? Why is nutrition essential to our daily lives? Nutrition is what your body requires in order for you to stay healthy.

Our bone structure is predetermined but we are able to modify our body composition by developing proper eating habits and daily physical activity. There are a number of physiological factors that occur during our bodies ultradian rhythms that influence our eating behavior. Early studies believed that the feeling of hunger was brought on by a sudden drop in blood glucose levels, but we have since learned that the fluctuation of glucose levels is very minimal and will actually return to normal with or without consuming food. New studies revealed the discovery of the hormone ghrelin.

Cultural Diversity and Diet By: Deborah Dominie Principles of Sociology SYG 2001 Instructor: Jonathan Brooks Everest University January 23, 2014 You have asked for our opinion about eating toasted ants, about eating fried frog legs, about eating puppies and kittens, and about eating raw monkey brains. You also stated in this assignment that if we were reared in the U.S. society more than likely we would think eating frog legs is okay; eating ants is disgusting; eating dogs and kittens; and eating raw monkey brains is downright repugnant. Then you asked us how we would apply the concepts of ethnocentrisms and cultural relativism to our perception of these different cultures. So therefore, in this essay you will find my opinions to these statements and the definitions to the different types of sociology theories and the terms for ethnocentrism and cultural relativism. The different cultures around the world have their own types of customs that they are used to having.
