The Effect Of Food Structure On The Delivery

In this assignment I will be describing the characteristics of nutrients and the benefits to the body.

The issue of health, and proper eating habits has been a growing trend in recent years, with the introduction of many chemicals and additives in the foods people eat. It is important to know what nutrients and vitamins are being put inside the body. As of December 12, 2007 it is mandatory for all prepackaged foods in Canada to be labeled with the “Nutrition Facts,” a summary of what is in the food. This includes the Calorie count, the 13 core nutrients with the % Daily value of those nutrients and, the full ingredients list. Similarly, this lab seeks to identify the major macromolecules present in an unknown solution, the same process that food scientist go through in the lab, when making the “Nutrition Facts” summary. The four main molecules that we will be testing for are monosaccharides, starches, proteins and lipids. It is because the purpose of the lab is to test for multiple macromolecules that the inquiry and testing process will be split into four independent tests for the presence of each respective molecule.

Nutrients required for the survival of mankind and other living creatures can be divided into two categories. They are macronutrients and micronutrients. There seems to be a lot of confusion over the difference between macronutrients and micronutrients. The main difference between macronutrients and micronutrients is that human body requires macronutrients in larger quantities whereas micronutrients are needed in smaller quantities. The major macronutrients are carbohydrate, protein and fat which contribute to the bulk of our food. They are the structural and energy-giving caloric constituents of our foods. Meanwhile, micronutrients such as vitamins, minerals and phytochemicals are essential

The influences of underlying health conditions can result in the need for specific nutrients as well as influencing what people are or aren’t able to eat.

The first section is set aside for the age of nutritionism; Pollan informing his readers about the history of food. Until William Prout and Justus von Liebig identified and build upon the term “nutrient,” it was just a set of words floating around as a concept in the early nineteenth century. William Prout, an English doctor and chemist, identified the first three principal constituents of food; protein, fat, and carbohydrate, terms in which we all are very familiar with. Justus von Liebig, the amazing German scientist who is known to be one of the founders of organic chemistry, built upon Prout’s discovery and declared that the mystery of animal nutrition has been solved. Although, Liebig had overlooked some things.

Nutrients can be grouped into six categories: carbohydrate, protein, lipid (fat), water, vitamins, and minerals.

Once again my mini-sub and I will be miniaturized (8 microns long) and witnessing another ‘Fantastic Voyage’ in a human body. This time I will be swallowed by George, a 55 years old man, while he is eating his meal consisting of a hamburger, French fries and a soda. I will pilot my mini-sub through George’s GI (gastrointestinal tract), which is the tube that starts with the mouth and proceeds to the esophagus, stomach, duodenum, small intestine, large intestine (or colon), rectum and, finally, the anus (Pansky, 2007). Along this pathway I will describe the digestion of George’s meal and the major structures that I will encounter. Arrived to the distal

Once again we have been miniaturized in the submarine to continue the fantastic voyage of the digestive system. We will be touring a 55-year-old male. The host will be having a hamburger, French fries, and a root beer. We will be tracing lunch through the digestion process. Digestion is the process of turning the food that is ate into energy needed to survive and involves creating waste to be eliminated. (Mohan, 2010). The digestive tract is a long twisting tube that starts at the mouth and ends at the anus, called the alimentary canal. The wall of this tube is fashioned of four layers of tissue. The layers are listed from the inside coat to the outside coat: mucosa or mucus membrane, submucosa, muscularis, and serosa. The hollow space

Food is digested by being broken down, by a variety of enzymes, into useful nutrients, which are transported around the body to places where they can be of use, and into waste products, which are excreted from the body. The digestive system is made up of a number of organs, oesophagus, stomach, liver, pancreas, gallbladder, and small and large intestines, these are then separated into the digestive tract and the digestive organs. The digestive tract is, essentially, a single continuous tube that begins at the mouth and ends at the anus, in a fully grown adult it is approximately seven metres long. Food travels through the digestive tract and the digestive organs produce the enzymes and chemicals that are responsible for

Nutrients are substances needed for normal bodily operations. Essential nutrients, derived from healthy food choices, are virtually indispensable to the body. Without them, the normal functions of the body begin to deteriorate. They must be derived via the diet.

The digestive system is the process that involves the mouth, esophagus, stomach, small intestine, large intestine and rectum. For the body to function, the body`s cells needs energy and that energy will come from the food we eat. All the food we eat contains nutrients, carbohydrates, glucose, lipids, protein and many more other substances. The only way the body can absorb and convert these nutrients into energy to our cells is through breaking down the large molecules into smaller pieces and moist by the action of enzymes.

Nutrients are essential to our bodies thru our entire lives at different levels. The six essential nutrients include Protein, Water, Fat, Vitamins, Carbohydrates, and Minerals. These nutrients are important for our bodies to function. I will be writing about 3 different stages of Mathews life and the essential nutrients he needs at that stage of his life.

There are seven major classes of nutrients: carbohydrates, fats, fiber, minerals, protein, vitamin, and water.

The digestive system contains nutrients, water, and electrolytes that the body needs to maintain a healthy lifestyle. “The organs of this system ingest, and absorb food and eliminate the undigested remains as feces” (Human Anatomy and Physiology, 2012). The process of the digestive system first starts by eating food through the mouth. After the food has been eaten, it then breaks down into subunits, process called digestion. Next is the movement of the food along the GI tract so all functions can be fulfilled. Then the absorption of the nutrients in the GI tract are delivered to cells through the blood. The elimination of indigestible molecules is the last step in the process. The alimentary canal walls have four tunics (layers). “Each of these tunics has a predominant tissue type and a specific function in the digestive process” (Human Anatomy and Physiology, 2012). The mucosa is the innermost layer and is a “wet epithelial membrane abutting the alimentary canal lumen” (Human Anatomy and Physiology, 2012). The mucous membrane “consists of a surface epithelium, a lamina propia, and a muscularis mucosa” (Human Anatomy and Physiology, 2012). The

Nutrients also have a diverse role to play in health treatments and outcomes. Conventional medicine has failed to recognize the diverse role that nutrient play in our healthcare.
