The Basics of the Food Pyramid

People who exercise more will have different diets to those who do not exercise. Carbohydrates are very important for athletes as it provides fuel. Carbohydrate is stored as glycogen in the liver and muscles, and released when needed during exercise. It is easily broken down to provide energy. The other source of energy is fat, but this cannot be converted into energy as quickly as glycogen.

1. Carbon, hydrogen, and oxygen make up carbohydrates. Small carbs contain twice as many hydrogen atoms as oxygen atoms; simple sugars, called monosaccharides, are the basic building blocks for

Of course, you think that the carbohydrates and starches go on the bottom, then fruits and vegetables, dairy, meat and poultry above that and finally at the top, saturated fats. I remember being quizzed on the pyramid in elementary school as well as having a health class with Mrs. Suplizio and having an entire unit on nutrition. We did not learn about what Pollan calls "whole foods," but more about nutrients. The teachers taught us to associate pasta and cereal with carbohydrates, milk and eggs with protein, oranges with vitamin C and cookies with fat. For many of us, these associations are now automatic. As Pollan points out, "Distinctions between entities as different as beef and chicken and fish have collapsed. These three venerable foods, each representing not just a different species but an entirely different taxonomic class, are now lumped together as mere delivery systems for a single

Carbohydrates have two functions which is, provides short term energy and structure in some organisms. They have an atomic makeup of Carbon, Hydrogen, and Oxygen, with a 2:1 ratio of Hydrogen to Oxygen. The monomer is a monosaccharide which contains a single sugar. A couple examples of this would be glucose, fructose, and deoxyribose which is found in DNA. Yet, foods with this monomer in it would be mostly fruits, candy, and soda. Carbohydrates also have a polysaccharide which is a polymer made of many monosaccharides strung together. Some examples of these are starch, glycogen, cellulose, and chitin. A starch is storage from glucose in plants(potatoes, pasta, waffles, and toast). Glycogen is storage from glucose in animals. Cellous is structure in plants (cell wall). Chitin is structure in animals (exoskeleton).

(Driskell 29) These simple carbohydrates are easily broken down, converted into glucose for the body and easily flow into the blood stream. The downside to this form of carbohydrates is that they are most common in the form of refined sugars or refined flours which retain very few vitamins after being processed. (“HealthStyle Fitness”) As the body uses this form of glucose a cycle begins which involves fluctuations of high and low blood sugar. This cycle works when blood sugar rises after the consumption of simple carbs and then as the blood sugar begins to drop the body demands more simple carbs to bring blood sugar levels back to up. The cycle that is formed essentially keeps the body from burning body fat because there is a continuous demand and consumption of simple carbohydrates. The second form of carbohydrates is that of complex carbohydrates which consist of polysaccharides, three or more monosaccharides. These complex carbs are found in the form of starch, fiber and glycogen (animal starch). Those complex carbohydrates consumed in the form of starch are found in plant foods like corn, wheat, potatoes, cereals, pastas, and beans. When they are broken down these carbs allow for the slow production and release of glucose into the blood stream and allowing for a consistent blood sugar level. (Guthrie 27) Dietary fiber is another form of complex carbs which are present in plant foods because fiber is

Carbohydrates are used for energy and structural support in cell walls of plants and exoskeletons of crustaceans and insects. They are also used to make cell structures and can make a large group of chemical compounds. Carbohydrates are also made up of carbon, hydrogen and oxygen. The testing solution for carbohydrates is Benedict and iodine. Next is proteins, they help bulk up all solid materials inside your body, such as your muscle, hair, skin, and inside organs. Proteins also make up some hormones which help with the chemical control in the body. They

Carbohydrates: any of a class of organic compounds that are polyhydroxy aldehydes or polyhydroxy ketones, or change to such substances on simple chemical transformations, as hydrolysis, oxidation, or reduction, and that form the supporting tissues of plants and are important food for animals and people.

Carbohydrates are composed of carbon, hydrogen, and oxygen. Carbohydrates can come from fruits, vegetables, and grains. There are two different kinds of carbohydrates. The first being simple carbohydrates, which are sugars. Glucose, fructose, and galactose fall under the sugar category. Then you have your complex carbohydrates, which are starch in grains, glycogen stored in our muscles, and fiber. When it comes to energy within our body glucose is a major source of energy. When our body does not get enough carbohydrates to supply enough glucose, our body will make glucose from proteins. I applied this to my life by making sure I eat fruits, vegetables, and grains to get my carbohydrates every single

Carbohydrates are macromolecules which and contains carbon, hydrogen and oxygen (C,H,O). There are also two types of sugars, sweet soluble and starches which are non-soluble. Sugars can also be single or simple sugars.Carbohydrates can be found in a wide variety of foods such as pasta, wheat and grains, rice, potatoes, fruits and sugars. Carbohydrates are broken down into

What are their functions?Carbohydrates- simple sugar. They are composed of carbon, hydrogen and oxygen. They are also monosaccharides.Lipids- They are fats, oils and steroids. Lipids store energy and also helps in the synthesis of vitamins and hormones.Proteins- They are a long chain of amino acids. They are the most complex and most diverse chemical composition.Functions of carbohydrates, lipids and proteins Carbohydrates- provides energy as they are the bod’s main source of fuel, needed for physical activity.Lipids- Lipids are used for storage of energy and forming cell membranes.Proteins- They do most of the work in cells and are required for the structure, function, and regulation of body tissue and organWhat do they look like?Lipids- They have long hydrocarbon chains that determine the way they act.Carbohydrates- Molecules combines of carbon, hydrogen and oxygen.Protein- A long chain of amino acids combined.48. What is metabolism? How are carbohydrates, lipids, and proteins metabolized? What role does enzymes play in metabolisms?Metabolism is the chemical process that occur within a living organism in order to maintain life.Carbohydrate metabolism- begins with digestion in the small intestine where monosaccharides are absorbed into the blood stream. Blood sugar concentrations are controlled by three hormones: insulin, glucagon, and epinephrine. If the concentration of glucose in the blood is too high, insulin is secreted by the pancreas.Lipid metabolism- are involved with Fatty Acid Oxidation to produce energy or the synthesis of lipids which is called Lipogenesis. Lipid metabolism is closely connected to the

The message from the visual about former food pyramid is very clear because one can easily get the message from it, i.e., one can understand the various food groups and the amounts he or she needs to ingest at a time. The visual is right for the story because the pyramid shows the type of food, amounts one can consume, and the importance depending on the rank in the pyramid (Locker, 2009). The design is appropriate because each of the foods in the pyramid has its natural color. The visual does not contain any information or symbol that is not significant meaning that it is free from chart junk. The visual has a clear message and, therefore, it does not mislead the reader.

Carbohydrates, fats and proteins are three energy-yielding nutrients. They can also be called macronutrients. Carbohydrates are energy-yielding nutrients because they provide four kilocalories per gram. Carbohydrates can include starch and sugar. Fats or lipids can provide nine kilocalories per gram. They are a form of energy that is concentrated. Proteins provide four kilocalories per gram. When someone eats these three macronutrients and they do not use energy right away, it is stored as fat in the body. If someone is very active, they will use the macronutrients as their energy. If someone takes in an insufficient amount of protein, the person will store it but will then make the person lose body weight because it

Nutrition transition is the energy expenditure and shift in dietary consumption that coincides, globalization are creating lifestyle changes that contribute to the nutrition transition. Markets have made these products much cheaper, and easier to produce which has in turn driven up their demand. Nutrition transition has its root in economic factors related to development within a

A carbohydrate is a member of a large class of natural organic substances. Carbohydrates are in almost everything we eat, sometimes in very small amounts but often times in substantial quantities. Some examples of common carbohydrates are sugars, starch and cellulose. Carbohydrates are important because they provide a storage of energy in our bodies that is quickly accessible. In fact, carbohydrates make up the major source of dietary energy for people all over the world (Stephen 1995). In addition, carbohydrate intake increases levels of a substance called tryptophan in the body, which releases serotonin in the brain. Whether this phenomenon affects our hunger and eating habits is

The term ‘’Carbohydrates’’ is defined as the carbon compounds which contains hydroxyl groups in large quantities (King, 2013). Carbohydrates are those organic compounds which have the empirical formula CnH2nOn, or (CH2O)n (Fromm 1997). Carbohydrates are one of the four types of organic compounds in living cells that are produces during photosynthesis and are the important source of energy in both plants and animals (Ahmed 2014). They are built from monosaccharides. These monosacchradies are the small molecules that consists of three to nine carbon atoms and differ in size and in the stereochemical configuration at one or more carbon centers. The simplest carbohydrates also contain either an aldehyde or ketone compounds (freeman 2002). Carbohydrates are classified as simple and complex carbohydrates. The classification of carbohtdydrates is based on the chemical structure of the food and how fast it absorbs. Simple carbohydrates contains single or double sugars in their chemical structure whereas complex carbohydrates consists of three or more sugars (ahmed 2014). There are four major types of carbohydrates depending on their chemical composition.
