Introduction

Nutrition is the relationship of foods to the health of the human body. Proper nutrition means receiving enough foods and supplements for the body to function at optimal capacity. It is important to remember that no single nutrient or activity can maintain optimal health and well being, although it has been proven that some nutrients are more important than others. All of the nutrients are necessary in different amounts along with exercise to maintain proper health. There are six main types of nutrients used to maintain body health. They are: carbohydrates, fats, proteins, vitamins, minerals, and water. They all must be in balance for the body to function properly. There are also five major food groups. The groups are: fats and oils, fruits and vegetables, dairy products, grains, and meats. A healthy diet and nutrition are important factors that help to keep our body in good health through our entire life. Food is very important to our life. Food provides nutrition for the human body's health. To stay healthy we should understand the inseparable relationship between diet and nutrition. When first starting this assignment I didn't think that I was going to learn anything new that I didn't already know about my eating habits. After writing down a days worth of food and drink and then analysing all the information and actually calculating out everything, I realized that there is so much more that I could learn in the future and will lean in the future about myself and the food that I eat. ...read more.

If a kidney stone becomes large enough to cause a blockage, it stops the flow of urine from the kidney and must be removed by surgery or other methods. Following a high-protein diet for a few weeks probably won't have much effect on bone strength. Doing it for a long time, though, could weaken bone. Protein is a vital nutrient, essential to your health. In its purest form, protein consists of chains of amino acids. There are 22 amino acids that combine to form different proteins, and 8 of these must come from the foods we eat. Our body uses these amino acids to create muscles, blood, skin, hair, nails and internal organs. Proteins help replace and form new tissue, transports oxygen and nutrients in our blood and cells, regulates the balance of water and acids, and is needed to make antibodies. Many people are putting their health at risk by eating to much protein. To get a right amount of protein in my diet I should avoid too much animal protein and include in my diet balance of carbohydrate and protein in ratio of two parts carbohydrate to one protein. Calcium is an essential mineral. Calcium works with phosphorous for healthy bones and teeth and with magnesium for a healthy cardiovascular system. Calcium is important for good sleep, the body's ability to use iron, keeping a regular heartbeat, and helping in the transmission of nerve impulses. ...read more.

Conclusion

Vitamin A is fat-soluble vitamin whose best-known role is aiding in night and colour vision. It also protects against skin respiratory infections and cancer. My intake of vitamin A was 843�g. Daily recommendation is 800�g. The most of vitamin A in my diet comes from milk (600�g), butter (100�g) and tomato (105�g). Vitamin A can be also found in liver, carrot juice, cheddar cheese and eggs. Water- soluble vitamins are not stored in the body so they are needed more frequently. Water-soluble vitamins are found in fruits, vegetables and grains. Vitamin C is a water-soluble, antioxidant vitamin. It is important in forming collagen, a protein that gives structure to bones, cartilage, muscle, and blood vessels Vitamin C also aids in the absorption of iron, and helps maintain capillaries, bones, and teeth. I had a huge amount of vitamin C in my diet. I managed to consume 121mg of vitamin C what is 100% over daily recommendation. Large doses of vitamin C can generally be taken without any problems, though some people may find that they have stomach problems with an intake of several grams a day. It is best to increase and decrease the amount taken gradually, as a sharp increase in vitamin C can cause diarrhoea, while suddenly cutting off a high daily dose can cause fatigue. The biggest amount of vitamin C in my diet comes from orange juice that contain 58.5�g. ...read more.
