There are 5 essential amino acids that are needed to make a complete protein. True of False
Aliun [14]
False. There are actually 9 essential amino acids that are needed to make a complete protein that is necessary for the dietary needs of a person. These amino acids includes Tryptophan, Isoleucine, Threonine, Lysine, Leucine, Valine, Methionine+Cystine, Phenylalanine+Tyrosine and Histidine. Generally, a complete protein can be gained from animal foods such as fish, poultry, animal meats and eggs, but it can also gain from selected plant foods as well. Incomplete protein can also become a complete protein when 2 or more incomplete protein are combined.

ElenaW [278]

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.

1. What does research show what happens to teenagers brains on junk food.
Jlenok [28]

Answer:

Unnecessarily eating low quality nourishments during youth could change mental health, prompting enduring horrible eating routine propensities. Be that as it may, similar to a muscle, the cerebrum can be practiced to improve determination. Expanded cerebrum pliancy during puberty implies the youthful brain might be more responsive to way of life changes.
