Nutrition Is Essential For Our Body

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

Essential minerals - Some electrolytes are considered essential minerals, meaning that they are unable to be made within the body and are an essential part of health.

Simple carbohydates should be elimated, including food such as white bread and pastries. These types of foods are processed and composed of refined fructose and glucose sugars. Simple carbohydates are smaller molecules and get broken down and absorbed by the body at a much faster rate, resulting in a quick source of energy. However, they will have you feeling hungry quickly, increasing the level of sugar in the blood and can have negetive health affects if consumed too much.

Food supplies us with many minerals, but the way in which our bodies are able to absorb them varies. The degree to which ingested nutrient is absorbed from food sources and is available to our body is called bioavailability. The bioavailability of minerals depends on many factors. The mineral content listed in food composition table for amount of a mineral in a food is just a starting point for estimating the actual contribution the food will make to our mineral needs. For example spinach contains much calcium but only 5% can be absorbed because of the vegetables high concentration of oxalic acid, a calcium binder. Usually 25% of calcium is absorbed by adults.

Minerals are essential to maintaining good health. They help our body absorb and use vitamins and act as catalysts for a number of chemical processes. Our bodies can manufacture a number of vitamins but minerals cannot be made in by our cells. We must obtain all the minerals we need from our diet or through supplementation.

Protein plays an important roll in our bodies. It helps to build and repair body tissue, keeps us energized and helps us fight off infections , make up eighteen percent of an adults body weight, and participate in every body function. That’s just five of many reasons why protein is important to each individual. You can have to much protein or not enough protein in your body. Amino acids are the building blocks of proteins. Hundreds of amino acids come together to form a protein. Proteins are sixteen percent nitrogen and is the primary source of nitrogen in the diet also carrying small resources

Carbohydrates are classified as simple or complex carbohydrates. Many dairy products like eggs and milk, meat, legumes such as beans, nuts, some cereal products are great sources of protein. Proteins are essential nutrients for the human body. Proteins serve as hormones and a source of energy. They allow the body to move, protect it against infection and disease and regulate important chemical reactions needed for life. Lipids consist of carbon, hydrogen, and oxygen atoms. They include solid fats and liquid oils. Lipids are important to the human body because they provide energy in which are necessary to the maintenance and development of the nervous and reproductive system. Plant-based foods such as nuts (peanuts, almonds, pecans, and pistachios) are great example of lipids. Lipids also contain animal-based foods like meat, fish, eggs, and dairy products like milk, cheese, and butter. Water is the four and final macronutrient class. Water is extremely essential for life, without life would be nonexistence. The water molecule is composed of hydrogen and oxygen atoms and makes up over half of the total human body weight. Everyday humans consume water either through foods they

The categories of lipids are fats, phospholipids, waxes, and steroids. Saturated fats are usually solid at room temperature. They are found in animal products like butter and cream. An example of a saturated fat is the cheese in my grilled cheese sandwich on Day 3. Saturated fats only have single bonds and also have the maximum number of hydrogen bonds in their fatty acid tails. Unlike saturated fats, unsaturated fats have double bonds which makes them liquid at room temperature and also have some hydrogen atoms missing in their tails. Unsaturated fats are mostly oils. The olive oil I used in my omelet in all 3 days is an example of an unsaturated fat. Trans fats are usually artificial and are made by adding hydrogen atoms to an unsaturated fat to reduce the amount of double bonds, which makes the fat saturated. This process is called hydrogenation. Hydrogenation makes the fat last longer and have the same taste. I did not have food containing trans fat in my log. The healthiest of all 3 fats are unsaturated fats because they contain more vitamins and reduce the risk of heart disease. Consuming saturated fats and trans fats increase a person’s chance to develop heart disease or a stroke. Type 2 diabetes can also arise when consuming too many trans

Proteins in our diet are essential to our bodies for the promoting of lean tissue growth. The function of immunity in our body needs foods that are full of protein. Essential hormones and enzymes depend on proteins for their making. Growth in children and adults, tissue repair and immune functions are all depended on proteins in their work.

Just like vitamins, minerals help your body grow, develop, and stay healthy. The body uses minerals to perform many different functions from building strong bones to transmitting nerve impulses. Some minerals are even used to make hormones or maintain a normal heartbeat. They are materials found in foods that are essential for growth and health. The minerals that are relevant to human nutrition are water, sodium, potassium, chloride, calcium, phosphate, sulfate, magnesium, iron, copper, zinc, manganese, iodine, selenium, and molybdenum. The five major minerals in the human body are calcium, phosphorus, potassium, sodium, and magnesium.

Sources of protein may come from meat, fish, eggs and dairy products. Large amounts of protein will not improve performance or muscle mass. That can only be achieved with the appropriate and specific training.

Nutrition is the process of providing the cells of the body with necessary materials for health and growth. These materials allow the cells to regenerate, restore, and support life.

Diet is food we eat in order to provide our body with the nutrients it need to carry out its functions. Nutrients the body needs are divided into two groups Macronutrients and Micronutrients.

Fats are a type of nutrient which is essential within a balanced diet. Dietary fats are essential as they give the body energy and supports cell growth. They also help to protect your organs and helps to insulate the body. Fats also helps the body to absorb nutrients and produce important hormones. There are two main types of fats which our body receives, these are saturated, and polyunsaturated. Saturated fats are usually obtained from animal sources, such as butter, cakes and biscuits. Polyunsaturated fats are mainly found in vegetable sources, such as sunflower oil, nuts and leafy greens.
