Questions from Students on March 26th:

Professor,   Thank you for sending out reminder emails, it is greatly appreciated and very helpful.   For the quiz, I hit submit after each question and it updated to “answered”. However, there is no option to overall submit the quiz. Is this okay? Can you see that I did it and my answers?
Hope you are safe and healthy,

Questions on March 25, 2020

Questions from later in the afternoon:

Good Morning Professor Dixon,   This is regarding the dietary assignment. So for this assignment I only have to keep track of my diet for only a single day? And then answer the questions and submit it through sakai?   Thank You,
Answer:  Dear _______:   Yes, Yes, Yes!!!!   But do a good job too!    Joe Dixon
Hi Dr. Dixon, hope you are doing well!
1) (specific question)
2) Attached below is my exercise assignment, which I have just finished. Before I submit it, I just want to check up with you on 2 things:
  1.  a) My total energy expended is a bit lower than the average male, so I wasn’t sure if I did any calculations wrong, I was wondering if you could quickly skim through to make sure.
  2. b) For question 3 on the questions, it asks to compare our calculated total energy expended with the one on a website that is not in service anymore, so instead, I went online and found another total energy expended calculator and used that instead. I was wondering if that’s ok with you.
  3. c) Otherwise, I think my exercise assignment is done, so I was wondering if you could check to make sure I hit all requirements. (this is the first one submitted so I will do it – but please don’t send me others!!!)
3) I have finished the dietary assignment as well as the exercise assignment after this, and am planning to review for the exam now. I just want to make sure I am not missing/shouldn’t be working on any other current quizzes/assignments (the reason I’m asking is all classes are online now so I don’t want one assignment you sent to slip through the cracks.  Thanks again for your help during these uncharted waters.
Stay safe,
Answer:   Hi,  Thanks for your best wishes!  You are the first to submit an Exercise Assignment!  It isn’t due to April 14th. Your assignment looks great.  Almost perfect!  One thing I saw is that swimming is not a Neat activity.  Golf may be on the borderline if it is done very casually.   So I would remove the swimming.  The hours look great though. It was great you went to another site to get your energy expenditure and that they were pretty close!  For your size and weight, the energy expenditure is right on!  Thanks for doing a great job!
I am glad you liked the assignment.  Do you like cheesecake?  LOL
BTW, I just put on TopHat a quiz that is due by Friday, March 27th at 10 am.  It should take 10 min to do! Stay safe too!
Joe Dixon

From Earlier in the Day:

Thank you for your response. Is it okay if I manually add my food and all the nutrients to the website as it does have an ‘add custom food’ feature? I take vitamin gummies every day and they are the only major source to fulfill my daily vitamin requirement. Should I add it to the analysis? All my vitamins and minerals are deficient (highlighted red) without them.   Best Regards
Answer: Actually, I prefer that you do not add vitamins because I want you to see what is coming from your diet alone. You can add them to your written diary. You can mention that you take vitamins in the written portion of your diet assignment. Yes, you can try to add custom foods.  I haven’t tried this yet. If you are successful please send me the foods you added and how you did it so I can see how it works.  Thanks for your great questions and help!  Joe Dixon
Good Evening Dr. Dixon,
My name is ________ and I just had a question regarding the extra credit slide. Is it okay if I exceed the 1 slide limit because I am doing a timeline and it happens to not all fit on one slide. It would only be a slide or two extra that I would need to use. Thank you so much for your time and have a safe rest of the year!   Sincerely,
Answer: Thank you for your email!  That will be fine.  I will set up an assignment portal in Sakai for it so don’t send them yet!  Thank you for helping me! Joe Dixon

Now some more questions from Students:

Emails from 3-24-2020

Question:  Hi Professor Dixon,  I saw on your blog site that someone had already made a comment and question about how the sum of their fat, carbs and protein kcal was larger than the total daily intake. I had the same problem and made a note of it on the first page as you directed. However, I still have a question. Since my calories did not match up, on slide 5 do I still have to include my total calorie intake for the day? Or can I leave it as it is? Also do I have to include the percentages or is what I have correct?
Thank you,
Hi Alaina,  Thanks for your email.  I saw your PowerPoint and it looks good.  For the percentages, just sum the Calories from Fat Carbohydrate and Protein and use that as the total.  So from that you can get a percentage contributed by each macronutrient.  Everyone is having the same problem!   Joe Dixon
Question: Dr. Dixon,  Greetings for the day! I hope this email finds you in the best health.
I’m ____________, a student of your Nutrition and Health 255 class.  I needed clarifications regarding academic expectations and the course in general. Firstly, since there are no live or online lectures will self-studying the PowerPoint presentations and the textbook help me score well in the exams? Secondly, I was trying the MyFoodRecord website to see how it works. I could not find several brands I consume on a regular basis. For instance, protein pancakes. I’ve done some regular calorie intake checks before I took the course and I used to use the MyFitnessPal app on my phone. It is literally the most convenient, informative, and versatile app. I just scanned my packet or box fill in the exact quantity and I had all the required details. I am from India, and at least one meal every day is home-cooked Indian food, the app even has those Indian cuisines. I wanted to know if I could use the app instead of the suggested website since it is far more accurate and it has literally everything. Looking forward to hearing from you.  Thanking you in advance.  Best Regards
Hi, Thank you for the email.  I will start the video lectures after Exam 2. For now, study from the Powerpoints and the Study guide.  And read the book for chapters 6, 7, and 8.  I don’t think MyFitnessPal has all the nutrients that the MyFoodRecord website has.  If it does, show me the output. In the meantime, try to make adjustments in the database.  For example, see how much extra protein there was in the protein pancakes compared to regular pancakes.  Then add that much (grams?) pure soy protein to you daily foods by putting in that extra amount.  There is no doubt it is a little difficult.  You can even compare the MyFitnessPal with MyFoodRecord.   Joe Dixon
Question:  Good afternoon Dr.Dixon,
this is ________, one of your students from your intro to nutrition course.  I just have a quick question about the Diet Analysis Project.  Do we have to include how much water we drink in our food intake record and/or input it in the “my food record” website?  Thank you!  Best wishes,
Hi, Thanks for your email!  No, you do not have to include water in your diet record!   Joe Dixon

Dear Dr. Dixon,   I am ______.  When I do the Diet analysis project, I noticed that the sum Calorie of fat, carbohydrate, and protein is larger than my daily intake Calorie, which is so weird.
Screen Shot 2020-03-22 at 9.19.04 PM
Answer:  Hi,
I don’t know why they didn’t match up – just put the figures in and make note of it!           Joe Dixon
Comment:  There are always little mistakes in these programs!
Question:   There are many foods missing from the choices available on the website. Do we have to manually add a custom food then? For example, there’s no vitamin water, iodized salt, breakfast biscuits, dried fruit and a few others. If so, how do I know which micronutrients are included in each one? Not all of them are listed on the nutrition facts. Also, what would the “ug” represent when making a custom food? Aside from that, I don’t have access to a printer. Am I able to just type over the Food Intake Record that’s meant to be handwritten?
Answer:  Hi, Thanks for the email!  Dried fruit is a tough one because it could come in so many different permutations. Iodized salt – you can adjust the salt by adding how much you use – a half teaspoon? Probably on the internet.  We are not worried about iodine – – the database doesn’t have it!  There are many kinds of biscuits listed – just pick the closest!  ug is microgram (also mcg)  I wouldn’t do a custom food.
You can just write it out  – the whole thing – on a piece of paper –  then take a picture or scan.    Can you put files into PowerPoint?
Joe Dixon
Hi Professor Dixon,
I just have a quick question regarding the Dietary Assignment. I noticed that we need a hand-written diary of our foods and beverages for one day, as well as screenshots of the foods we entered into the dietary online website. My question is, what is the difference between what we are writing out by hand and what we are inputting into the system? Thanks,
Answer: Hi, Thanks for your great question.  The written one is the one you write down, etc.   The screenshot of the foods you enter should match the written one.  But if there is a mistake, then I’ll be able to see it. Or you will be able to see it.  Say you put in 1 gallon of orange juice instead of 1 cup – the vitamin C would be very, very high in your nutrient read out for the day.  So we would be able to figure it out.  I’m not trying to trick you.  It is just a check that you put the foods in right.  Plus it is a nice read out of your foods for a day!    Joe Dixon
Question:  Sun 3/22/2020 5:14 PM
Dear Dr. Dixon,    Hello I just want to clear up a few questions I had.  For the quizzes which are now considered homework assignments, will they be posted every week at a certain time? Also just to double check we don’t need to log onto the course at a certain time, it is all posted no Sakai, correct?  When is the exercise and USDA assignment due? Sincerely,
Answer:    Hi,  Thanks for the email!
I will let you know when the quizzes are posted as homework.  You’ll have 48 hours to do them.
You will need to log on for exam 2 during class time on March 31, st. I moved the exam to this date.
The exercise and USDA assignments will be posted this week – I’ll let you know then the due dates.

Nutrition and Health – Spring 2020 – March 19th Blog During Spring Break

On March 13 we finished Chapter 7 by going over Oxidative Phosphorylation.  During the lecture I mentioned that the drug dinitrophenol uncoupled Oxidative Phosphorylation because it caused proton (hydrogen) leak through the membrane.  I also mentioned that people have tried to use it as a weight reduction drug. However, if you take too much, it may kill you because you can’t make enough ATP.  Below is a recent paper that describes the death of a 17-year old body builder.

I put a pdf of this article in the Resource Folder – Please read it to learn about this unfortunate story!

I also wish to tell you that a student in class came up to me after class and told me about an experience she had when taking a weight loss drug.  One day she took 2 pills instead of the one she normally took.  She felt that she developed symptoms very similar to those described in the lecture –  she became very hot, dizzy, and she felt heart palpitations. She couldn’t remember the name of the drug but she felt it was a generic weight loss drug.  I suspect that it had dinitrophenol in it as the active agent.
