CHAPTER #1 INTERACTIVE ASSIGNMENT- NUTRITION 1325-01
what is the difference between a macronutrient and a micronutrient?
macronutrient: - nutrients required in grams per day - carbohydrate - fat - energy-yielding nutrient micronutrient: - nutrients required in milligrams or micrograms per day - vitamins - minerals - non-energy-yielding nutrient
complete the sentences:
1. the usual pattern of foods that you choose to eat is referred to as your diet. 2. the foods that you eat contain nutrients, chemicals that are necessary for proper body functioning. 3. a(n) essential nutrient is one that must be provided by the diet because it cannot be produced by the body in the amount that is needed. 4. the failure to consume adequate amounts of nutrients can lead to noticeable and measurable physical changed that are signs of deficiency disease. 5. deficiency disease can cause subjective health problems called symptoms, which may include headaches, dizziness, and fatigue.
can you match the phytochemical description and food source with its phytochemical category?
carotenoids (beta-carotene): - orange, red, and yellow fruits/vegetables that may reduce the risk of certain cancers and macular degeneration. alkaloids (caffeine): - a stimulant effect that is found in cocoa, coffee, and tea. capsaicinoids (capsaicin): - the pain-relieving properties that are found in chili peppers. fructooligosaccharides: - a compound found in foods such as: onions, bananas, asparagus, and wheat that may stimulate the growth of beneficial bacteria in the intestines. phenolics (quercetin): - the antioxidant activity from fruits, vegetables, and red wine that may inhibit cancer growth and reduce the risk of heart disease.
complete the goals of Healthy People 2020:
- to attain higher-quality, longer lives that are free of preventable disease, disability, injury, and premature death. - to achieve health equity by eliminating disparities to improve the health of all groups. - to create social and physical environments that promote good health for all. - to promote the quality of life, healthy behaviors, and healthy behaviors across all life stages.
match the common household units for measuring food ingredients:
1 gallon --> 16 cups 1 pint --> 2 cups 1 quart --> 4 cups 1 tablespoon --> 3 teaspoons 1/2 cup --> 8 tablespoons
complete the sentences:
1. a food or beverage that contributes excessive amounts of unhealthy solid fat, added sugars, and/or alcohol to the diet is high in empty calories. 2. a food or beverage that contains more key beneficial nutrients in relation to its total calories is called a(n) nutrient-dense food. 3. the energy value of a food in relation to its total weight defines how energy-dense a food is.
complete the sentences:
1. the studying of nutrition means that you must also have an understanding of chemistry; the study of the composition and characteristics of matter and changes that occur to it. 2. the smallest living functional unit in an organism is called a(n) cell. 3. the making of proteins, generation of energy, and disposal of waste are all chemical processes that in total are referred to as your metabolism. 4. phytochemicals are non-nutrient compounds that are made by plants and may influence health. 5. a few nutrients function as antioxidants; these are substances that protect other compounds from being damaged or destroyed by certain environmental factors.
match the people described below with the key nutrition concepts that they are violating:
a variety can help to ensure the nutritional adequacy of a diet. --> Tina is trying to lose weight. she only eats grapefruit because she heard that grapefruit contains a chemical that speeds up metabolism, resulting in "natural" weight loss. for each nutrient, there is a range of safe intake. --> Theresa complains to a friend that she is tired all the time. the friend suggests that she take a megadose of a B vitamin each day for "energy". after taking the vitamins for a couple of weeks, Theresa develops an upset stomach and a facial rash. we have a such thing as "good" and "bad" foods. --> Jim has diabetes. he doesn't consume fresh fruits because he thinks they have too much sugar.

what statements are true and false regarding genetic modification?
false: - the FDA in the United States has not approved any genetically engineered foods for human consumption. - genetic modification involves changing the genetic makeup (DNA) of soil where seeds are grown. true: - most of the soybeans, cotton, and corn grown in the United States is from seeds of genetically modified organisms. - genetic modification of organisms in an example of a biotechnological advancement.
