In the field of nutrition, diet is simply the amount of food ingested by an organism or individual. It can be defined as how much of the diet is comprised of carbohydrates, protein, and fat. This is because the body needs all three of these substances in order to maintain its health and well being. It also needs a certain amount of vitamins, minerals, and water.
There are three important principles that form the basis for a balanced diet: nutrient absorption, expenditure, and toxicity. Nutrient absorption refers to how fast and how efficiently the nutrients are absorbed and used by the body. Excess calories are used immediately by the body, but not stored. At the same time, the body is not over loaded with calories and neither is it under-absorbed. Expenditure on the other hand refers to how many calories have been burned up and what the balance is after eating.
The definition of diet (entry 2 of the diet code) is: An ideal diet plan for controlling or losing weight involves eating less calories than the body needs more often than the total caloric intake for a specified number of days. So, a diet that tells you to eat one thousand calories less than your daily requirement would be considered severely restricted diet. The second principle, expenditure, pertains to the amount of energy used for activities and the total energy supply. The third principle, which is the toxins, pertains to the intake of substances by the body that can harm it. So, a diet that limits the intake of salt, sugar, alcohol, cholesterol, and meat is a good example of a balanced diet.
A diet has two major components: the total fat intake and the nutrient intake. The total fat intake refers to the food that is eaten and the amount of calories consumed. Total fat intake is measured by calculating the calories that are taken in by the body and then multiplying this by the number of servings of each food group. The nutrient intake is measured by ingesting a daily diet of food items. It is important to note that the food groups of the World Health Organization (WHO) are categorized into six groups, which are healthy, moderately healthy, unhealthy, and dangerous.
The medical definition of diet, as entered in the first entry of the document is to maintain an optimum consumption of foods that provide calories and other nutrients to meet the requirements of the body. For the individual to achieve a balance between macronutrients (carbohydrates, protein, vegetables, fruits, and oils) and macronutrients (fats, fiber, and minerals) in the diet, the amount of each should be at least harmonious with the other. This is the general idea of a diet, which aims to give good health. For example, although total fat intake may be important to some people, they should still be within healthy limits.
The fourth principle is diet soft drink. In order to meet dietary recommendations, a dieter should limit his or her intake of diet soft drink because it contains calories and other toxins that contribute to weight loss. If the dieter drinks diet soft drink regularly, the body will be overwhelmed by the toxins, which may have adverse effects on the body. This could also result to an increased risk for diabetes, high blood pressure, heart disease, and stroke.
