Supplying enough energy to support the many functions of the body at work and play is one of the chief functions of food. This energy comes from the fats, carbohydrates, and proteins in the food you eat. Without energy stored in our bodies- our bodies would not function. It is required for the molecules to move in and out of the cells, for breaking down large molecules and also foe building new ones. The role of energy in our body consists of the breakdown of large, complex molecules to the simplest form to release energy, this is called catabolism.
There are two different types of carbohydrate, simple carbohydrates (or sugars) and complex carbohydrates (starches and fibre). Proteins are a vital nutrient which us used by the body for growth and repair, it is very important for infants and children also individuals who are ill or injured. one characteristic of proteins is that they are made up of amino acids. They are complex molecules that can promote good health. Lipids are insoluble within water, they have high energy content and can be metabolized to release calories, but they have many other uses as well.
We are all different from heads to toes; our body system is different from everyone else. There are many points that Pollan is trying to point out, but I will provide you with different meals that I want to share with you and that will be healthy and not everything is like Pollan tries to explain. There are many different types of bodies, most likely divided into three sections the first one would be slim, then it would be a fit body, and lastly a thick body. Thin people just have a different type of metabolism which burns the food faster. This means that they need different types of nutrition’s.
Diffusion helps to remove dissolved carbon dioxide from the blood and into the expelled air from lungs. Diffusion is the molecules (gas or liquid) moving from high concentration to low concentration. M1: Discuss the role of energy in the body. Our bodies need energy to work properly. The energy we need and use comes from the type of foods we eat.
Macro nutrients are the structural, energy providing parts of food they are required in small amounts by the body. Macro nutrients include carbohydrates, lipids and proteins. Micro nutrients include trace elements, vitamins, minerals, antioxidants and phytochemicals. Micro nutrients are only required in small amounts in the body but, they are essential for metabolic processes like breaking down carbohydrates within the body. The quality and quantity of the nutrients in food can differ greatly and is dependent on the types of food a person eats and also the quality of the food.
They provide calories and energy for the body, aid in tissue repair, helps growth, provide cushion for the organs, and absorb vitamins. Too much or too little macronutrients can result in poor health or a range of diseases. The American Heart Association (2014) website say that, “too much protein can cause many chronic diseases or make chronic diseases worse”. Examples of diseases that can be caused by too much protein in a person are osteoporosis, kidney failure, kidney stones, and gout. Too much fat in a person’s diet can also cause disease when over consumed.
They also require waste substances and gasses such as Carbon Dioxide to move out of them. Many small animals can often manage to meet this demand, however larger animals often need a transport system with a pump to ensure they meet the demand. This is all because of their difference in surface area to volume ratio as surface area plays a vital role in the transfer of substances. The main principle of this movement of substances is diffusion. Diffusion is where particles move from where they are in an area of high concentration to where they are in an area of low concentration.
This assignment will evaluate the importance of homeostasis in maintaining a healthy functioning of the body. If homeostasis did not work properly in the body then there are many problems that could arise. Diabetes is one of those problems: Diabetes Diabetes is “a permanent change in your internal chemistry that results having too much glucose in your blood” because the body cannot use it properly. (Rudy, 1999, Page 10) Glucose comes from digesting carbohydrates and is also produced by the liver, carbohydrate comes from many different kinds of foods and drink, such as Wholegrain cereals such as Weetabix and Shredded Wheat, Brown rice, Pasta and Potatoes. “Diabetes can be tackled in different ways- by insulin and diet” (Rudy, 1999, page 19) Diet, when someone had diabetes it is best for their health to cut right down on the unhealthy foods, and stick to the health foods, this is due to the effectiveness of the medication you are on.
E1 describe the main food groups that are essential to meet the basic needs of the body There are five main food groups, These groups are carbohydrates, proteins, fats, vitamins and minerals and water. Each type of food plays a significant role in our body but excesses or deficiencies of certain types of food can also harm the body and produce a negative impact on our health. Food and the nutrients obtained from food are vital to keep the body healthy and alive. Nutrients are required in order to build and repair cells and body tissues, maintain the organs and bones in optimum working condition and to provide energy, fuel and warmth. Protein is needed in the diet for growth and repair of the body.
A vending machine for example is fast food which is bad for health. Most of the food that surrounds us can be bad but we need to make good choices. Overeating habit is not the best answer to healthy lifestyle. Velychko 4 Prose, Francine. "The Wages of Sin."
