Answer:
As stated in Chapter 1, the translation of human energy requirements into recommended intakes of food and the assessment of how well the available food supplies or diets of populations (or even of individuals) satisfy these requirements require knowledge of the amounts of available energy in individual foods. Determining the energy content of foods depends on the following: 1) the components of food that provide energy (protein, fat, carbohydrate, alcohol, polyols, organic acids and novel compounds) should be determined by appropriate analytical methods; 2) the quantity of each individual component must be converted to food energy using a generally accepted factor that expresses the amount of available energy per unit of weight; and 3) the food energies of all components must be added together to represent the nutritional energy value of the food for humans. The energy conversion factors and the models currently used assume that each component of a food has an energy factor that is fixed and that does not vary according to the proportions of other components in the food or diet.
Explanation:
The unit of energy in the International System of Units (SI)[8] is the joule (J). A joule is the energy expended when 1 kg is moved 1 m by a force of 1 Newton. This is the accepted standard unit of energy used in human energetics and it should also be used for the expression of energy in foods. Because nutritionists and food scientists are concerned with large amounts of energy, they generally use kiloJoules (kJ = 103 J) or megaJoules (MJ = 106 J). For many decades, food energy has been expressed in calories, which is not a coherent unit of thermochemical energy. Despite the recommendation of more than 30 years ago to use only joules, many scientists, non-scientists and consumers still find it difficult to abandon the use of calories. This is evident in that both joules (kJ) and calories (kcal) are used side by side in most regulatory frameworks, e.g. Codex Alimentarius (1991). Thus, while the use of joules alone is recommended by international convention, values for food energy in the following sections are given in both joules and calories, with kilojoules given first and kilocalories second, within parenthesis and in a different font (Arial 9). In tables, values for kilocalories are given in italic type. The conversion factors for joules and calories are: 1 kJ = 0.239 kcal; and 1 kcal = 4.184 kJ.
Which of of what? but dont worry the answer is C joining a club
Answer:
For example, TH2 cells directly stimulate B cells to class switch, producing immunoglobulin isotype IgE, which is useful in targeting parasitic worms.
Explanation:
Immunoglobulin E, or IgE, is a protein present in low blood concentrations that is usually found on the surface of some blood cells, especially basophils and mast cells, for example.
Because it is present on the surface of basophils and mast cells, which are cells that normally appear in higher blood concentrations during allergic reactions, IgE is usually related to allergies; however, its concentration may also be increased in blood due to diseases caused by parasites. and chronic diseases, such as asthma, for example. This is because TH2 cells directly stimulate B cells for class switching, producing the IgE isotype of immunoglobulin, which is useful in targeting parasitic worms.
Answer:
The group that received the placebo is the control group.
Explanation:
This group is known as the control group.
