Nutrients correct answers Components of food required for the body's functioning
Roles:
-Provide energy (Calories)
-Building material
-Maintenance and repair
-Support growth
Six categories/classes of nutrients: correct answers -Water
-Carbohydrates*
-Fat*
-Protein*
-Vitamins
-Minerals
*Energy-yielding
Essential nutrients correct answers Nutrients that the body cannot make, or cannot make fast
enough, from other raw materials- Nutrients must be obtained from food to prevent deficiencies
These are= water carbohydrate, lipids,protein, vitamins and minerals
Calories correct answers Measurement of food energy.
Units of energy
The unit to measure the energy in foods is a kilocalorie- is the amount of heat energy necessary
to raise the temperature of a kilogram of water by one degree celsius.
Food correct answers Any substance that the body can take in and assimilate that will enable it to
stay alive and grow
Nutrition correct answers The study of the nutrients and other biologically active compounds in
foods and in the body. A young science
Diet correct answers The foods a person usually eats and drinks
Malnutrition correct answers bad diet/nutrition. Excess or deficiency of nutrients that can cause
health issues.
Chronic diseases correct answers Failure of body organs. Related the person's poor diet/nutrition.
Examples: heart disease, cancer, adult bone loss, dental disease, diabetes. Influenced by food
choices.
Prevention: genetic constitution, level of physical activity, and lifestyle
, DNA correct answers an abbreviation for deoxyribonucleic acid, the molecule that encodes
genetic information in its structure.
Genes correct answers units of a cells inheritance, made of the chemical DNA. Bits of genetic
material that hold the instructions for making a human being.
Elemental diet correct answers -Composed of purified ingredients of known chemical
composition
ex- Lifesaving for people in the hospital who cannot eat ordinary food.
-Intended to supply all essential nutrients to people who cannot eat foods.
Nutritional genomics correct answers -the science of how nutrients affect the activities of genes
and vice versa.
Nonnutrients correct answers Compounds other than the six nutrients that are present in foods
and have biological activity in the body. Ex- baked potatoes gives us more than just nutrients.
Phytochemicals correct answers Nonnutrient compounds in plant-derived foods that have
biological activity in the body.
Energy-yielding nutrients correct answers The nutrients that the body can use for energy.
Carbohydrates (sugar and starch) and fats (saturated and unsaturated fats, fats are properly called
lipids) are especially important energy-yielding nutrients.
Calorie Values of Energy-Yielding Nutrients correct answers Carbohydrate-4Cal/g
Fat(lipid)- 9Cal/g
Protein- 4Cal/g
Alcohol- 7Cal/g
Grams correct answers Measurement of food and nutrient quantities
Units of mass. A gram (G) is the mass of a cubic centimetre (cc) or millilitre (mL) of water under
defined conditions of temperature and pressure.
Dietary supplements correct answers pills, liquids, or powders that contain purified nutrients or
other ingredients.
energy correct answers the capacity to do work. The energy in food is chemical energy, it can be
converted to mechanical,electrical, heat, or other forms of energy in the body. Food energy is
measured. The energy that fuels the body's work comes indirectly from the sun by way of plants.
Plants capture and store the sun's energy in their tissues as they grow.
organic correct answers Carbon containing. Four of the six classes of nutrients are organic:
carbohydrate, fat, protein, and vitamins. They include only food made by living things and do
not include carbon dioxide and a few carbon salts.
Both water and minerals are not organic.
