Chat Two for Exam One…..good job all!
(hosted by Amy Allen-Chabot Ph.D., R.D.– Nutrition Program Coordinator at AACC)
Fatimah >>i'm a newbie...does this really help?
Barbara >>It helps you to study a whole lot
Tiffany >>it was hard for me last chat but they were giving out good study information
Fatimah >>ok cool...thanks
Instructor >>Hi folks....looks like a familiar group to some extent. I'm Dr. Amy Allen-Chabot, the nutrition program coordinator and chat host. How are you all this evening.
Tiffany >>hello
Tiffany >>good and urself
Kristin >>hi, good, how are you?
Whitney >>hi
Tracey >>hello! fine, thanks!
Instructor >>I'm good...
Whitney >>good, you?
Instructor >>Any questions from you all this evening
Barbara >>not yet
Instructor >>I got a private message asking about chat transcripts.....there is a link to the transcripts on the content page under module 3
Tracey >>i was just wondering about the format of the exam: # of questions, mult choice, etc?
Instructor >>Depends on which class you are in......if you are taking the course online from Dr. Allen-Chabot, Chester or Somanchi, the test is all multiple choice..50 questions in 50 minutes.....that is 60 seconds or so a question so you need to know the info well and you won't have time for notes or the book. The lecture class for Amy Allen-Chabot has short answer and fill in the blank and has 1 hour and 15 minutes....not sure about exams for Prof. Hager, Israel, Hartnett or Stott.
Instructor >>Okay....I'll throw out questions...what general topics would you like to cover?
Fatimah >>digestion
Instructor >>okay...what else
Barbara >>vocabulary
Tracey >>how about the macronutrient calculations
Whitney >>the DV calculations
Instructor >>okay....for vocabulary you don't need to know an exact definition...just have a notion of the meaning so you could sue the word in a sentence or describe the meaning in your own words.
Instructor >>Okay.....lets see.,....what route does the food take when you eat it.?
Instructor >>mouth ---> esophagus---> etc
Tracey >>would that be an example of a question that we would see on the exam?
Melissa >>stomach small intestine large intestine
Kristin >>mouth-esophagus-stomach-small intestine-large intestine-rectum
Barbara >>What about therapeutic procedures, pathology and diagnostic procedures
Fatimah >>mouth, esophagus, stomach, small intestine, large intestine, rectum
Instructor >>sure...anything on the self assessment question page or in the tutorials is fair game...and anything covered in the lectures
Instructor >>good Fatimah....that’s right....not sure what you are asking Barbara.....those things won't be on the test that I can think of. I don't believe I ask anything like that on the self assessment
Tracey >>so if we are comfortable answering the self assessments and tutorials, then we should be prepared for the exam?
Instructor >>you bet....
Fatimah >>is there going to be an equal amount of questions from all the chapters that we've covered so far?
Instructor >>what is the role of the pancreas in digestion
Tracey >>good to hear!
Tiffany >>
Instructor >>the questions are fairly well split between modules one, two and three
Tiffany >>does the nutrition study guide that came with the book help for the exams?
Melissa >>secretes enzymes
Tracey >>introduces bicarbonate into sm intestine to neutralize the chyme?
Fatimah >>the pancreas secretes substances into the GI tract
Fatimah >>*tract
Kristin >>pancreas breaks down fat- pancreatic enzymes lipase and amylase
Melissa >>releases hormones
Instructor >>(in answering test questions...I can speak for myself, Dr. Chester and Dr. Somanchi. I don't know what the tests are like for the other professors)
Instructor >>good...so secretes enzymes for digesting macronutrients and also secretes bicarbonate to bring the pH of the chime up to a more normal (less acidic) level
Barbara >>The pancreas produces digestive enzymes, hormones, and insulin.
Instructor >>the pancreas does release hormones as well.....but mostly that has to do with blood sugar regulation. Insulin is a hormone
Instructor >>If you were taking the class online from Dr. Allen-Chabot, Dr. Somanchi or Dr. Chester, I would not rely too much on the textbook study guide....can't speak for the other professors
Tiffany >>ok
Instructor >>okay....what is the name of the sphincter that separates the stomach from the small intestines
Fatimah >>pyloric?
Kristin >>pyloric
Melissa >>pyloric
Instructor >>right....good.
Instructor >>what are the three segments of the small intestines?
Fatimah >>duodenum, jejunum, and Ileum
Melissa >>duodenum jujuem ileum
Tracey >>pyloric
Instructor >>good...a bit of spelling / typing help needed but you are there....
Tracey >>duodenum, jejunum and ileum
Instructor >>there we go!
Instructor >>okay....where are most of the nutrients absorbed?
Melissa >>sm intestine
Kristin >>small intestine
Tracey >>small intestine esp jejunum and ileum
Instructor >>good.
Instructor >>What organelle in the cell is responsible for energy production
Kristin >>mitochondria
Tracey >>mitochondria
Melissa >>mitochondria
Instructor >>good....what does peristalsis mean?
Fatimah >>mitochondria
Melissa >>wake like motions
Instructor >>of what
Fatimah >>pushing of food by muscle contraction
Instructor >>good......
Tracey >>rhythmic muscle contractions along gi tract to propel the food down the tract
Instructor >>what is the difference between passive diffusion and facilitated diffusion?
Fatimah >>passive-cross freely
Kristin >>passive diffuses right across, facilitated needs help across
Fatimah >>facilitated-carrier needed
Tracey >>facilitated diffusion utilizes carrier molecules to bring substances across the cell membrane
Kristin >>like proteins in a membrane, that’s facilitated
Instructor >>good...where might we find villi and microvilli in the body and what is their purpose?
Melissa >>sm intestine
Fatimah >>in the small intestine
Fatimah >>it increases surface area for absorption
Tracey >>in the small intestine lining the lumen
Kristin >>increased surface area
Instructor >>very good......what is the general role of sphincters in the GI tract
Tracey >>they help increase the absorptive area
Melissa >>act as valves to control the flow of material
Tracey >>to regulate the flow of the chyme through the tract
Kristin >>allow the food to enter and exit, control what comes in and goes out
Fatimah >>prevents backflow from the duodenum to the stomach
Instructor >>good....which is more complex...tissues or organs?
Kristin >>organs
Tracey >>organs
Fatimah >>organs
Whitney >>organs
Instructor >>lets hear from some of you have not been responding....
Melissa >>tissues
Jennifer >>I can't type as fast
Jennifer >>lol
Instructor >>yea...we keep a lively pace here....
Steve >>yeah...
Instructor >>organs are made of tissues...so we say that tissues are less complex and tissues group together for form organs
Melissa >>oops
Instructor >>you have a label and it says a serving of product x has 19 grams of fat and 290 kcalories. What percent of the kcalories are coming from fat?
Instructor >>show the math
Steve >>19x9
Melissa >>59
*+**** Kristen-- entered ANPH0002007FA_Room3. Time:Wed Sep 19 20:22:33 2007
Jennifer >>59
Steve >>171/290
Steve >>59%
Melissa >>19 g fat x 9kcal per g =171/290=.59 x100= 59%
Tracey >>59%
Instructor >>good...you can say 19 grams of fat * 9 kcals per gram = 171 kcals from fat. then divide the part by the whole to get the percent. 171 kcals from fat / 290 total kcals = .589 or 58%
Steve >>wouldn’t you want us to round?
Steve >>if its .589
Steve >>to 59?
Instructor >>make sense....anyone stuck here.....need to do two steps because one number is in kcals and one in grams
Melissa >>yeah do we round or not
Instructor >>sorry...yea...59%
Fatimah >>i just gotta remember the kcals per gram
Instructor >>okay.....your label says the product has 19 grams of fat....what is the percent daily value for fat for this product.
Tiffany >>same here
Steve >>fat 9kcal per gram and protein and carbs are 4
Fatimah >>thanks steve:)
Melissa >>29%
Jennifer >>29
Fatimah >>29%
Jennifer >>19?65
Jennifer >>/
Melissa >>19g/65
Instructor >>good......so 19 / 65 = x/100 (19 is to 65 as x is to 100 to get the percent) or just divide 19 by 65 (dividing the part in food by the whole amount allowed per day)
Instructor >>If a food has 45% of the DV for sodium, how many milligrams does it have. DV for sodium is 2400 milligrams
Jennifer >>1080
*+**** Marion-- entered ANPH0002007FA_Room3. Time:Wed Sep 19 20:27:21 2007
Kristin >>1080 milligrams
Tracey >>1080
Kristine >>2400 * .45 = 1080
Steve >>i guess i should get a calculator
Whitney >>1080
Fatimah >>1080--->.45*2400
Instructor >>good....looks like you guys are on top of this....good to see.....
*+**** Edna-- entered ANPH0002007FA_Room3. Time:Wed Sep 19 20:28:18 2007
Instructor >>Here is a tough one.....Jack eats 3100 kcals a day....what is the maximum amount of carbohydrate he should eat in grams
Kristen >>2015
*-**** Fatimah-- left ANPH0002007FA_Room3. Time:Wed Sep 19 20:28:56 2007
Kristen >>g
Tracey >>2015
Kristen >>no that's in kcal...
Instructor >>(hint..one number is in kcals and one is in grams)
Fatimah >>775g?
Jennifer >>503
Kristen >>8060g
Tiffany >>775g
Instructor >>Good...I've given you something challenging.
Fatimah >>is it 775?
Instructor >>lets see....first we need to know that the maximum recommended amount is 65% of kcals
Steve >>42.25
Tiffany >>4/3100=775?
Kristen >>I'm b/t 503 and 775
Steve >>42.25!!!
Jennifer >>2015/4??
Kristen >>how'd you get 42.25
Fatimah >>how did you get that steve?
Tracey >>could you show how you arrived at that #?
Instructor >>so that would be 3100 kcals * .65 = 2015 kcals from carbs. Then we need to convert 2015 kcals to grams so we divide by 4 kcals per gram ...so 2015 / 4 = 504 grams
Steve >>well 65% is the maximum number of carbs we should have and 65 grams of fat is whets recommended
Steve >>so multiply 65 by .65
Steve >>huh
Instructor >>no....that won't work....because the recommendation is 65% of kcals from carbs....we aren't talking about fats here.
Fatimah >>oh ok...got it
Steve >>oh never mind
Instructor >>Make sense....this isn't a labeling question.....we need to know the National Academy of Sciences recommendations to do this problem
Marion >>I am just now getting here, sorry I am late.
Instructor >>and we need to know the 4 kcals per gram for Carbs.
Instructor >>Does everyone see what I did above??
Kristin >>yep
Kristen >>yes, good problem
Tiffany >>yes
Jennifer >>i got it
Kristine >>yes
Tracey >>yes, just need to practice these more
Marion >>Yes.
Fatimah >>yes, i got it now
Instructor >>Lets try it again. Jodi consumes 2100 kcals, what is the minimum amount of fat she can have in one day in grams
Jennifer >>47
Kristen >>47g
Instructor >>(according to the National Academy of Sciences at least)
Kristin >>47g
Tiffany >>47
Instructor >>good....great....we have made good progress here.
Kristen >>2100* .20 = 420 / 9 = 47
Instructor >>any questions here.......
Fatimah >>47g
Marion >>Got if finally. 47g.
Instructor >>good....
Instructor >>what is anecdotal evidence?
Tiffany >>not for me i just need to study more or the kcals stuff
Tracey >>personal observation
Jennifer >>our own personal thoughts/observations
Marion >>anecdotal evidence is something personal we relate into a science
Instructor >>yea......like "my aunt eats that every day and she is 98 years old"
*+**** Kristin-- entered ANPH0002007FA_Room3. Time:Wed Sep 19 20:37:28 2007
Instructor >>give me an example of an inverse correlation
Marion >>you got me....more to study
*-**** Kristin-- left ANPH0002007FA_Room3. Time:Wed Sep 19 20:37:54 2007
Kristin >>as one thing increases, the other decreases, right?
Tracey >>when a high fiber diet is consumed a lower incidence of colon cancer is observed?
Instructor >>good Tracey....or how about "as calcium intake goes up, blood pressures go down"
Jennifer >>something goes down, while something else increases
Instructor >>okay.....you take a group of folks with leukemia and match them by age, gender, ethnicity to a group without leukemia.....what type of study
Whitney >>case control?
Kristen >>i agree w/ case control
Fatimah >>case control
Tracey >>case control
Jennifer >> yeah
Instructor >>good...you want to find out if hot dogs cause leukemia......what type of study do you need.
Jennifer >>intervention
Marion >>Case control. You guys are to fast....
Jennifer >>I know, lol
Tracey >>human intervention / clinical trial
Kristen >>intervention
Fatimah >>human intervention study
Instructor >>okay...how would you do the study?
Marion >>human intervention
Fatimah >>have a group eat hotdogs and another not eat them and follow it over time?
Tracey >>select one group (experimental group) that is given hot dogs to eat and a control group that never eats hot dogs?
Kristin >>experimental and control group, administer hot dogs to experimental and not control, monitor it over a long period of time
Jennifer >>would you need a "placebo"??
Instructor >>hmmm....sounds good.....who wants to volunteer to eat hot dogs every day, knowing that they might cause cancer or have been associated with cancer in observational studies.....any volunteers??
Melissa >>no thanks
Kristen >>haha, yummm
Tiffany >>noooo
Fatimah >>i'll leave it
Instructor >>you can see the difficulty in doing intervention studies....its not always ethical
Marion >>what about animal intervention, I don't like it though...
Instructor >>What is wrong with this hypothesis "Eating healthy is associated with a longer life"
Jennifer >>may be"
Kristen >>too vague....
Jennifer >>not "is"
Marion >>it is a to vague
Melissa >>what is considered a longer life
Instructor >>could do animals for sure...but then it may not apply to humans...so every situation has limitations
Tracey >>it does not make a measurable prediction
Kristen >>you can't measure how long is"longer"
Melissa >>yeah cant measure it
Kristin >>not something you can really test
Instructor >>right...eating healthy is hard to define. I think you all have worked through the research tutorials...is that right?
Fatimah >>it is a health claim, nothing really proven
Kristen >>....as well as healthy eating is defined differently among different cultures
Tracey >>yes
Marion >>yes. it takes a long time, but is worth it
Instructor >>a hypothesis doesn't have to be true...its just a best guess....but it has to be specific enough to study.
Fatimah >>are you going to post this chat to be reviewed tonight?
Instructor >>The tutorials are definitely worth it.....you will see very similar questions on the test.
Jennifer >>the flash cards from mod 1 were helpful
Jennifer >>interactive flash cards
Instructor >>you bet.......I usually take out names but there are a lot and it will take me a few hours.....does anyone object if I just remove last names and leave first names in place.
Instructor >>good tip Jennifer.....thanks for letting me know
Marion >>no worries with me
Tracey >>that's fine
Instructor >>and the others
Fatimah >>not at all
Steve >>i don’t really care to b honest
Kristine >>no
Tiffany >>no its fine
Kristen >>that’s fine
Fatimah >>this is really helpful!
Whitney >>its okay
Jennifer >>great
Instructor >>good......
Melissa >>don’t care
Instructor >>you can let me know privately if you want me to take your name completely out.
Instructor >>Okay.....which is more precise....the AI or the RDA
Tracey >>RDA
Tiffany >>RDA
Whitney >>RDA
Kristine >>RDA
Jennifer >>yea
Kristen >>agreed
Instructor >>right.....is the RDA likely to be higher, equal to or lower than the EAR
Tracey >>higher
Whitney >>higher?
Kristen >>higher
Fatimah >>higher
Marion >>Higher
Jennifer >>im not sure
Instructor >>higher is right...the RDA is two standard deviations above the EAR....or we could just say its designed to cover 98% of the populations needs rather than just 50%
Jennifer >>oh okay
Instructor >>Except for what item where the EAR is the same as the RDA
Tracey >>except for the macronutrients, right?
Instructor >>not the macronutrients but you are close
Tracey >>fats?
Instructor >>the guidelines for the macronutrients are based on kcals
Kristen >>micronutrients
Marion >>micronutrients?
Tiffany >>micronutrients
Instructor >>not nutrients but __________________
Instructor >>this is something that if you ate too much, it would be bad....even if it were just a little too much
Tiffany >>microminerals?
Tracey >>minerals?
Steve >>vitamins
Instructor >>over time if you ate even a little too much, you would gain too much body fat
Kristen >>calories...
Jennifer >>calories
Melissa >>ul
Instructor >>yea......right....kcals.....the RDA for kcalories is equal to the EAR....
Instructor >>but the RDA for nutrients 9vitamins, minerals) is significantly higher than the EAR.
Instructor >>a little more vitamin A than you need would not hurt you so they set it high enough to cover everyone......but a little too many kcals would add up over time....
Instructor >>make sense
Jennifer >>yes
Kristen >>yep
Marion >>yes
Fatimah >>yes
Instructor >>I will make a statement and you tell me what pyramid it applies to.
Instructor >>refined carbohydrates at the top!
Jennifer >>Harvard
Marion >>Harvard
Fatimah >>Harvard
Tracey >>Harvard
Instructor >>good.......olive oil has a separate category
Kristen >>Mediterranean
Jennifer >>Mediterranean
Fatimah >>Mediterranean
Marion >>Mediterranean
Whitney >>Mediterranean?
Tracey >>Mediterranean
Instructor >>good......the narrative says you should have half your grains as whole grains
Jennifer >>mypyramid
Melissa >>mypramid
Kristen >>mypyramid
Marion >>USDA Pyramid
Instructor >>good....legumes and nuts are in a separate category
Fatimah >>usda
Tracey >>my pyramid
Fatimah >>Harvard
Jennifer >>Harvard
Instructor >>and......
Tracey >>Mediterranean?
Jennifer >>med
Fatimah >>Mediterranean
Marion >>Mediterranean
Instructor >>good...so nuts and legumes have separate categories in the Harvard and the Mediterranean
Instructor >>You can sort of see that the Harvard pyramid is influenced by the dietary patterns of the folks along the coastal areas of the Med

Fatimah >>health
Edna >>health
Jennifer >>health
Melissa >>health
Kristine >>health
Instructor >>right.....good.......
Marion >>a health
Instructor >>Okay......you guys did great.....this is always fun and I think helpful to many. Any questions from you all before we call it a night?
