Nutrition is the biological and nutritional process by which an organism uses energy from the environment to support its normal functioning. It involves absorption, assimilation, production, utilization, biosynthesis and excretion. Nutrition is a comprehensive science that has been implemented since prehistoric times to improve health, decrease risk of disease, promote growth and prepare the body for further health challenges. It is a way of life that has been studied, modified and improved over the years.
Nutrition refers to the study of the foods that humans need to live a healthy life in society. This includes carbohydrates, proteins, and fat. Carbohydrates include breads, cereals, pasta, potatoes and certain fruits; proteins are meat, milk and eggs; while fats are vegetable oils, animal fats and some fruits. Each food type provides different vitamins, minerals, hormones and enzymes, and other nutrients that are good nutrition. The combination of these foods provide the body with the basic nutrients necessary for its daily activity.
To understand the concepts behind nutrition, it is useful to look at examples that illustrate how nutrition functions. For example, there is a four-part process that occurs during digestion, which is called the primary process. This process involves breaking down the food into the main sources of nutrition, the secondary process, which involve storing the energy that was used in the digestive process in the form of fat, and the last process, which provide the nutrients to the body.
One important part of good nutrition is vitamin c, or Vitamin C. Vitamin C is found in many foods, but is especially present in citrus fruits, broccoli, peppers, cantaloupe, oranges, strawberries, tomatoes, berries and the majority of vegetables and fruit. This vitamin aids in the formation of collagen, the cells that make up bones and teeth, and helps strengthen the immune system. It also aids in the maintenance of healthy skin and cartilage and can reduce the risk of certain cancers.
Another important aspect of nutrition is heterotrophic nutrition. This term refers to feeding the bacteria or fungi that live in the intestine rather than feeding the plants or animals that make up the main food chain in the ecosystem. These organisms are known as probiotics, which thrive on living in an environment where there is a constant supply of nutrients. Different types of probiotics exist depending on their needs, such as lactobacilli in the mouth and bifidobacteria in the gut. Holistic medicine recognizes the beneficial effects of these different modes of biotechnology and incorporates them into a comprehensive form of health care.
The concept of biotechnology is related to the field of nutrition, but it also has other components. The food we eat today is much higher in fat, sugar and salt than it was just 50 years ago. Most people are not adequately replacing these nutrients through their diets, which can lead to a variety of health problems, some of which are associated with malnutrition and deficiencies of vitamins and minerals. This process of micronutrient absorption is referred to as biopharmaceutical nutrition and relies on the use of specific micronutrients to provide a healthy body through the digestive process. There are two ways to deliver nutrients to the bloodstream, and they include absorption and administration through exogenous routes.
Intravenous nutrition delivery systems allow for the administration of nutrients directly to the bloodstream. Commonly used drugs to provide energy to perform different types of physical activities are ATP (adenosine triphosphate), glycine, ATP optimized proteins (PEPCK), ribose and glycogen. Many of the different types of nutrients can also be administered orally, although the nutrient concentrations may vary. It is important that you understand the full extent of what is contained in your daily diet before beginning a regimen of supplementation.
Vegetables and fruits make up a major part of the average person’s diet. The majority of food consumed is composed of fruits and vegetables, which supply a wide range of minerals, carbohydrates, proteins and fibre. You may be familiar with many fruits and vegetables such as bananas, oranges, apples, avocados, carrots, broccoli, spinach, lettuce and peppers. A majority of Western countries include a lot of fresh fruits and vegetables in their daily diets, which can make up a major portion of their diet. The benefits of consuming lots of fruits and vegetables is clear, especially when it comes to increasing your levels of health, vigour, energy and vitality.
