While it is possible for a human being to live for more than one hundred years, many people in the US are dying much younger. The main reason for this is the food they are putting into their bodies. Indeed, many Americans consume too much junk food and fail to eat a balanced diet. The damage that this does to their health sends many of them to an early grave.
Nutritional science relates to the practice of correct food consumption. Good nutrition involves eating the right amount of healthy foods each day to support your growth and repair any damaged cells. This is achieved through sensible dieting. Combining good nutrition with lifestyle choices like regular exercise, not smoking, stress management, and not drinking too much alcohol, is the key to a healthy life.
Your body requires three fundamental nutritional components. These are carbohydrate, fat and protein. Carbohydrates (carbs) provide energy for humans and animals. Without carbs, your body can not function properly, and you might experience fatigue, muscle cramps and poor mental alertness.
Nonetheless, too many carbs will lead to increased fat storage, which will make you gain weight eventually. Carbs are comprised of long sugar molecule chains, which the body converts into glucose. An excessive amount of glucose in your body can result in a common condition called diabetes. Carbs are a vital part of correct nutrition, however you have to balance your intake if you want to maintain a healthy diet.
The other primary nutritional component is fat. Fat gives your body energy reserves, in case your blood sugar runs low after several hours without food. Your body needs fat because it helps you to survive in warm and cold temperatures, by insulating your skin. If you do not have enough fat in your body, you will be susceptible to several types of diseases and conditions. Fat is a vital building block for hormones like leptin, that affect your body weight, metabolism, and your reproductive and immune systems.
Protein is the last of the important dietary components. In the absence of protein, your basic bodily functions could not work properly, and you would suffer from malnutrition. Protein facilitates many of your essential bodily processes. Each protein in your body has a specific purpose. It provides structural support for cells and transports small molecules and atoms throughout your body. Also, it functions as an enzyme and stimulates countless chemical reactions in your cells. It acts as an antibody to protect you from bacteria and viruses as well.
Minerals and vitamins are another necessity to support your bodily processes. They strengthen the immune system, help your organs and cells to do their job, and support normal development and growth within your body. If you did not consume any minerals or vitamins, your body would find it very difficult to work properly.
Being aware of what you consume is a vital part of sensible nutrition. This is why food products have labels on them displaying the nutritional content in each package. This allows shoppers to get a good idea of what they will be placing into their stomachs. Foods rich in carbohydrates include sugar, rice, bread and potatoes. Generally, food that promotes the development of muscle tissue is rich in protein and fat (for example, meat and eggs). Often, food containing minerals and vitamins comes from green vegetables and plants.
If you want to enjoy a healthy existence, you need proper nutrition for your body, along with an active and sensible lifestyle. Anyone can achieve the wellness they desire. All it takes is a little forward planning coupled with some will power. Adding juicing to your diet doesn’t hurt!
