1Molecules in food contain chemical energy that cells use to produce ATP. Food also supplies raw materials your body needs to build and repair tissues.
- AVerdadero
- BFalso
2why do we need to eat?
- Awe eat to gain energy
- Bfood supplies raw materials used to build and repair body tissues
- Cboth of the above
- Dneither of the above
3nutrients are substances in food that supply the energy and raw materials your body needs for growth, repair and maintenance.
- AVerdadero
- BFalso
4the nutrients that the body needs include:
- Awater, carbohydrates and fats
- Bwater, carbohydrates, fats and minerals
- Cwater, carbohydrates, fats and proteins
- Dwater, carbohydrates, fats, proteins, vitamins and minerals
5water is the most important nutrient because:
- Aevery cell in the human body needs water
- Bmany of the body's processes including chemical reactions take place in water
- Cwater makes up the bulk of blood, extracellular fluid and other bodily fluids
- Dwater can be lost from the body when you sweat, in urine and with every breath you exhale
- Ehumans need at least 1 liter of fluid each day
- Fall of the above
6simple and complex carbohydrates are a major source of energy
- AVerdadero
- BFalso
7fats help the body as they
- Aabsorb fat soluble vitamins
- Bare part of cell membranes, nerve cells and certain hormones
- Cboth of the above
- Dneither of the above
8when there are only single bonds between the carbon atoms in the fatty acids, each carbon atom has the maximum number of hydrogen atoms and the fat is said to be
- Asaturated
- Bunsaturated
9these fats have one or more double bonds between carbon atoms which reduces the number of hydrogen atoms in their fatty acids.
- Asaturated fats
- Bunsaturated fats
10these fats are usually liquid at room temperature, such as vegetable oil
- Asaturated fats
- Bunsaturated fats
11unsaturated fats that are modified by adding hydrogen to them or processed are
- Atrans fats
- Bsaturated fats
12these fats are solid at room temperature and have a longer shelf life
- Asaturated fats
- Bunsaturated fats
- Ctrans fats
13because many vegetable oils contain more than one double bond, they are called
- Asaturated
- Bpolyunsaturated
- Cunsaturated
14proteins have a variety of roles in the body including:
- Aproteins supply raw materials for growth and repair of structures such as skin and muscle
- Bmany enzymes that control chemical chemistry by increasing the rates of chemical reactions are made of proteins
- Cproteins have regulatory and transport functions (e.g., insulin is a protein that regulates blood sugar levels and hemoglobin, a protein found in red blood cells helps transport oxygen )
- Dproteins can be used as energy sources when other nutrients such as carbohydrates are in short supplu
- Eall of the above
15proteins are polymers of amino acids
- AVerdadero
- BFalso
16the body is able to synthesize 12 of the 20 amino acids used to make proteins and the other 8 are called essential amino acids
- AVerdadero
- BFalso
17organic molecules that the body needs in very small amounts are called vitamins
- AVerdadero
- BFalso
18most vitamins are needed by the body to help perform chemical reactions
- AVerdadero
- BFalso
19there are two types of vitamins
- Afat soluble and water soluble
- Bunsaturated and saturated
20these vitamins are fat soluble
- AA,C, D, E
- BA, D ,E, K
21water soluble vitamins include
- AC, D,,B
- BC, B
22fat soluble vitamins can build up small deposits of these vitamins for future use, but water soluble vitamins dissolve in water and cannot be stored in the body and therefore should be included in foods eaten each day
- AVerdadero
- BFalso
23inorganic nutrients that the body needs usually in small amounts are called minerals
- AVerdadero
- BFalso
24a balanced diet provides nutrients in adequate amounts and enough energy for a person to maintain a healthful weight
- AVerdadero
- BFalso
25a balanced diet provides nutrients in adequate amounts and enough energy for a person to maintain a healthful weight
- AVerdadero
- BFalso
26food labels can be used to choose healthful foods because:
- Athey provide general information about nutrition
- Bthey provide specific information about the product
- Cthey can be used to determine if you are consuming enough of some of the important vitamins and minerals
- Dall of the above
- Enone of the above
27when using food labels it is important to remember that percent daily values are based on a 2000 calorie diet
- AVerdadero
- BFalso
28people who are more active than average have greater energy needs and when a person stops growing or becomes less active their need for energy decreaes
- AVerdadero
- BFalso
29these factors contribute to the rise of obesity in the US over the last several decades
- Ainactive lifestyles
- Bhigh calorie diets
- Cboth of the above
30The American Heart Association recommends a diet with a maximum of 30% of calories from fat, of which only 7% should be from saturated fats and 1% from trans fats
- AVerdadero
- BFalso
31fat contains about 9 calories per gram and carbohydrate and protein contain 4 calories per gram
- AVerdadero
- BFalso
32foods that contain a high amount of any type of fat are high in calories
- AVerdadero
- BFalso
