Describe Nutrition

Carbohydrates, proteins and lipids are known as macronutrients as the body needs masses of these nutrient components in order to carry out the bodies’ essential functions.

Nutrition is defined “as the science that links foods to health and disease. “ Nutrition is also called nourishment that provides food for support of life. Nutrition involves the process of humans ingesting, digesting, absorbing, and excreting food substances.Food provides energy in the form of calories needed to maintain all body cells. Nutrients are the substances obtained from food that are an important factor to promote growth & maintain a healthy body through an individuals’ life.

My daily diet should contain a balance of proteins, carbohydrates (carbs), and lipids (collectively called macronutrients). According to Kirby (2011), micronutrients are substances such as vitamins, and minerals that are essential for healthy growth and developments. The body only requires small quantities of micronutrients and without them serious problems can arise. The role of each micronutrient makes proteins, carbohydrates, and lipids equally important in my diet. Proteins are important for repair and tissue growth, helps the body to make enzymes and hormones, as well as preserve lean muscle mass and is a source of energy. Carbohydrates are the body main source of energy and are easily broken down into glucose

Nutrients are the substances obtained from food that are vital for growth and maintenance of a healthy body throughout life.

The three macronutrients are carbohydrates, protein, and fat (McKinley Health Center, 2008). It is important to that macronutrient intake be within the recommended intake range. Having a diet that consists of too much or too little of a macronutrient could be harmful to the body. If you eat too many macronutrients, you could gain fat and if you eat too little macronutrients you could lose healthy fat, which would cause the body to break down. If you consistently eat too little protein, carbohydrates, or lipids, the body would be malnourished, which could have devastating effects on your health.

Carbohydrates: one of the main types of nutrients. They are the most important source of energy for your body. Your

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.

Course Description and Content: Incorporates principles of human nutrition, essential nutrients, nutritional needs of different age groups, and nutrition research. Focuses on the relationship between nutrition, physical fitness, lifestyle, and health, with supporting emphases on consumer awareness, evaluation of nutrition information, eating disorders, and the importance of a balanced, varied diet.

Fats are important not only for humans, but all life forms. It is a necessary part of the

We need some fat in our diets. Fat provides back up energy if the blood sugar supply runs out, protects are organs from shock, helps transmit nerve impulses and helps transport nutrients and metabolites across cell membranes. My intake level is in between the normal range. You can find fats in all types of food. There are two types of fat saturated and unsaturated. The type of fat we want are fat to come from is unsaturated fats. If you have a deficiency in fats you could have dry skin, hair loss, low body weight and bruising. If there is an excessive amount of fat you could be at risk for obesity, high cholesterol and hypertension. My current intake level is normal so I am going to leave it where it is.

During the three days of documented intake, my fiber consumption was only 24.3% of the daily recommendation. Fiber helps promote proper digestive functions, helps lower cholesterol, and helps in lowering the risk of diabetes and heart disease. My intake was too low based on the recommended consumption, and according to the data, I should eat more foods that are rich in fiber. These can be insoluble fiber sources like wheat bran and nuts or soluble fiber sources like oats, beans, and apples. The only foods that provided fiber in my meals were the bagels.

We are required to obtain certain amount of nutrients from food. Food can simply divide into 2 groups, macro-nutrients and micro-nutrients composition. Both of the groups mentioned do affect the metabolism rate. According to Hulbert and Else, dietary fatty acid will affect the metabolism rate and some of the polyunsaturated fatty acid will increase the metabolism rate (1999). Meanwhile, different kinds of animals have their own unique requirement for macro-nutrients, such as proteins, carbohydrates and fat. Moreover, most of the food intake is driven by achieving the required protein intake. Animals on a low protein diet will over eat carbohydrates and fat until the protein requirement has been satisfied. If this case

The health benefits of fiber are endless, but its main assets include lowering cholesterol, controlling blood sugar and maintaining a healthy weight (Anderson et al., 2009). Lowering cholesterol and heart health go hand in hand, as high cholesterol may lead to heart disease. Soluble fibers work the most efficiently at lowering cholesterol, as they attach to pieces of fat in the blood and remove them. Examples of soluble fibers include oats, barley, nuts, seeds, beans, and some vegetables. Not only do they effectively lower overall cholesterol, but they especially work to reduce bad low-density lipoprotein, better known as LDL. LDL is the main contributor to the blockage of arteries, so, therefore, cutting the levels of LDL will lead to less total buildup of fat and a decreased chance of developing heart disease. Fiber also works to control blood sugar levels. This can be extremely beneficial to individuals with diabetes, due to the fact that they produce inadequate amounts of insulin. Consequently, resulting in them having to monitor blood sugar levels on their own. Often times simple carbohydrates will lead to quick spikes in blood sugar. However, this is not an issue with complex carbohydrates, since fiber counteracts them by slowing the absorption of glucose. As a result, blood sugar levels will not immediately rise, making it less difficult
