|What is nutrition? Why is nutrition essential to our daily lives? | |Nutrition is a science that allows individuals to link food to health and disease. This is highly important because nutrition | |allows individuals to understand the essential link between what he or she intakes and what and how that (intake) has an effect | |on his or her body. This understanding then gives way to individuals having the ability to understand what he or she should eat | |and how much in order to lead a healthy life. This science has given birth to things we learn about quite often such as the food | |pyramid that outlines what and individual should be taking in on a daily basis and how much. |
|What is the connection between nutrition and health? | |The connection between nutrition and health is knowing what an individual should put into his or her body in order to lead a | |healthier life. Again, tools such as the food pyramid (which is updated as new discoveries are made) educate and inform | |individuals what he or she should be eating and how much.

One reaction vitamins support is releasing the trapped energy in | |carbohydrates, lipids, and proteins. Vitamins do not hold and calorie value to the body though; vitamins simply support the | |chemical reactions. | |Minerals are simple inorganic structures; because minerals are simple structures they are not destroyed during cooking. Minerals | |may get lost in water when being cooked if the water is then discarded. Minerals help with the nervous systems, water balance, | |and structural systems (as well as other cellular processes). Like vitamins, minerals hold no calorie value to the body. |
|What does it mean to eat a balanced diet? Why is food choice important for good nutrition? | |A balanced diet means an individual is getting all of the appropriate portion sizes and serving sized of all the food groups. | |This means making sure that the individual is not eating a lot of protein but no...
