Concept explainers

Nutrition and diet

We are involved in several daily activities. These actions need a significant quantity of energy. The food we eat provides this energy. Food is necessary for development, repair, and other living activities since it supplies energy. All of these are part of the living practice known as nutrition. Nutrition is the study of nutrients in food, how the body uses them, and the relationship between diet, health, and disease. Nutritionists employ concepts from molecular biology, biochemistry, and genetics to understand how nutrients affect the human body. Nutrition also looks at how people can use their diet to reduce their risk of disease, as well as what happens when they ingest too much or too little of a nutrient and how allergies emerge.

Johnny is a hardworking family man. He delivers food orders day and night while riding his bicycle. His co-delivery boys tease him as the “Iron Man of Albay”, because he is so energetic and doesn’t seem to get tired easily. He even travels long distances on his bike. One day, while eating at Aling Tess’ carinderia, which he patronizes, he was served with a meal he regularly orders. He was given a soup, few chunks of meat and its ‘sarsa’, two and a half cups of rice, and a banana. The extra one-half cup of rice was freely given to her by Aling Tess, teasing him that he might get emaciated from working very hard. To that, Johnny responded that he isn’t fat. He never gets fat. In the afternoon, on his way to deliver an order, Johnny got intercepted by a police traffic enforcer, Pat. Goyong Fernandez. Johnny was alarmed. He was making up excuses on his mind on how to evade extortion, for he knew that he didn’t commit any traffic violation. However, Goyong just wanted to check if he was…

Background“Eat eggs and exercise to live longer! ”Obviously, this ‘headline’ is fictitious, but it got your attention, didn't it? Reports of new research findings in the area of food andhealth seem to get a lot of media coverage, after all, food and health issues are of interest to nearly everyone. Reporters,academics, and health professionals all want the latest information —as do consumers. A single study and the reports surroundingit can send many people in search of the latest food or supplement holding the promise of good health.Frustrated and confused by the tremendous amount of food and health information reported nowadays , many people wantsimple certainties to help them protect their health through diet. The trouble is that single studies rarely provide such certainty,although they often get big headlines.The media, health professionals, and educators are the gatekeepers of today's food and health information.

We understand what happens if humans do not get enough to eat. We can see what happens when peopleovereat; resulting in excessive weight gain. The human diet can lead to heart disease, cancer, diabetes, and is the most significant cause of both death and disability in the world.By looking at the broad influences of food and nutrition policy here in the united states. The Farm Bill, environmental regulation, food production policy, and food safety are categorically the most significant sources influencing foodsproduced for consumption here in the United States.Using those four categories, and Marion Nestle poses this question in her book Eat, Drink, Vote.

Find a topic in nutrition that interests you and show me that you know where a "scientist" should be getting their information. Compare and Contrast this with information that is easily found in the media. for example: say you were interested in the effect of Vitamin D in your diet and the risk of you developing Corona Virus symptoms after exposure. you could easily find Social Media articles related to this BUT it is important that vou know where to find evidence based peer reviewed science articles. This will require that you learn how to research topics, interpret the findings and properly cite them as an academic for this assignment find 2 articles (one non-scientific and one peer reviewed) and write a short summary (1 or 2 pages) of the similarities and differences ( compare and contrast) the information the articles provide. some things to consider: (you must include discussion of these things for full marks) the credentials of the author(s) the organization that is publishing…
