Class 28 – Nutrition and Health – Spring 2020 – May 1st – Last Class of the Semester – Go Over the Review Sheet for the Final Exam

Update on the Class and Comments on April 30th 2020:


I hope you got to see Marijke’s class on Tuesday. It was fabulous! She has such amazing experience – having been involved in International organizations and having lived in many countries! Yay Marijke! Thank you so much for being a great TA!

Again, I was absolutely amazed at the Diet Assignments. They were the best ever! Some students submitted only a PowerPoint or a word document, and we are trying to get that straightened out.

We are almost done grading the Exercise assignments. They are also very good! Please see my comments on total energy expenditure in the lecture I gave last Friday. I am still amazed that some of you still think you only do 3 to 5 hours of NEAT a week! You should wash your house’s floors more often, or wash the dishes every day for your parents! I have been washing lots of dishes as our dishwasher is broken. It kills my back! I am getting criticism from my Editor about the term NEAT. She doesn’t like it and wants me to come up with another term. I wish Jim Levine didn’t throw the term thermogenesis in there. I think just non-exercise activity (NEA) is better. Right now I am thinking about just Daily Activity (DA). I dunno though.

I have also looked at some USDA graphing /table assignments. They are also amazing! I hope that you will get ideas about how to use this database in future projects. Look at my advice concerning this assignment on the blog a week ago or so.

Tomorrow is Class 28 of the semester—the last class!   It will be mainly going over the Review Sheet – so if you can – Print your review sheet and go over it tonight!

Don’t forget the Mineral quizzes on TopHat. Just a hint – many of you could do well just taking them without seeing the lectures. But to do very well, you need to review the lectures.

Stay safe out there!

Saturday Blog during the Pandemic – April 25th – Nutrition and Health – Spring 2020

Diet Assignment Grades were uploaded to Sakai this Morning!

On the whole the diet reports were the best ever!  Most students received a grade of 60/60.  Marijke or I read every single one.  If you received a bad grade, it was most likely due to the fact that you did not upload one of the parts of the assignment.


During yesterday’s Lecture (Lecture 26, Friday, April 24th) I went over the diet assignment in detail.  This material will be on the final exam, so if you missed the lecture, please see the PowerPoint and the recorded lecture on Sakai.


On Tuesday, April 28th, Marijke will give a lecture on nutrition in Pregnancy etc.  This will be the last lecture for the semester.


I hope you are all safe and healthy!

After Trace Minerals today we have finished the curriculum for the course.  For the 4 classes that are remaining we will have 2 special lectures and 2 review lectures.  I need to finish the grading of the Diet assignments and the Exercise assignments. I have a reading explaining parts of the exercise assignment.  I will also try to answer any of your questions from the course.

A few days ago I put a quiz on TopHat for the Water soluble vitamins.  I will put additional quizzes on TopHat too.


FINAL EXAM –  I will put the final exam on TopHat as a Take home Open Book Exam using the Home Work function.  It will be open on TopHat for about 4 days and will have an absolute due date because I want to finish up all the final course grades fairly early.

Scientists Have Discovered the Origins of the Building Blocks of Life

Hi Dr. Dixon,  I hope you are doing well. I was wondering if we would get points off if our calorie intake from the diet assignment did not match the total energy expenditure by a significant amount? Also, on a side note, I was wondering when you were going to post the live lecture videos on Sakai, or are they already posted? If so, how do we access them?  Thank you,
Answer: Hi,   No, all of these calculations are just estimates.   The recorded lectures can be found in the Sakai Meeting Tool.   Joe Dixon
USDA Assignment Questions
Hi, Mr. Dixon,   _____ here. I don’t have Excel, so I tried using Google Sheets to access the worksheets in the Dairy Products section. However, I am unable to access the worksheets in Google Sheets. I will do my best to try to fix this issue, but I’ll let you know if anything else comes up.   Sincerely,
Answer: You might want to use the Apple version of Excel to access them!   You have plenty of time.  Maybe call a friend for help.  Or Google this question for an answer.  Joe Dixon
Hi Professor Dixon,   Thanks! I just have 2 questions on the water-soluble vitamins quiz, 1 on question 1 and the other on question 5.
For question 1, what do water soluble vitamins do, I know in your lecture you said as a joke, it acts like little pacmans and makes you go faster, however, we also learnt that they help enzymes, carry electrons, and help with energy. So I’m a bit confused on which one of the two I should put for that question.
For question 5, I know that you said that the cell does not have buildings in it, so we shouldn’t put that answer on the exam. So for the quiz, would we just put that niacin is the cell’s power line, since it transfers hydrogens and electrons? Thanks for your help,
Answer: Hi, You have to figure out the answer to question 1.  It is pretty obvious!   Question 5  – The answer is in the PowerPoints for sure!

Where We Are – April 14th – Nutrition and Health – Spring 2020

Where are we in the Course?  Actually, we are very close to the end!  See the Synopsis:

We just finished Major Minerals today, and on Friday I will go over the Trace Minerals!

Here is an important Update on potassium. I said in class that potassium is extremely important for counter acting sodium.  This is still very true!   But the Potassium DRIs have been recently revised.  See the next two slides.  This is very important for several reasons:

1.  The % DV (Daily Value) for potassium given in the diet analysis program must be way off.  I can tell you that it has not been corrected yet in the diet analysis program.

2. This shows you that the DRIs for a nutrient can be updated as new information becomes available available.

3.  The potassium DRI value is still an AI, and it is not yet a RDA.  What does this mean?

More questions about the Exercise Assignment – Monday 4-13-2020


Hello Dr. Dixon, I am confused about the section for kcal content of favorite snacks because the snacks I am putting have a very low kcal content. For example, I put that one of my favorite snacks are Lays Barbecue Chips and on a standard bag it says that it is only around 150 calories. If this is too low, should I use the kilocalories for a whole case or is this fine?
Answer: Hi, 150 Kcal is fine for your favorite snack!  Why would you put in a whole case?  How much is a case?  Joe Dixon
A repeat for the Blog:
Good evening Dr. Dixon,  this is _______again from your Nutrition class.
This time I have a couple of questions about the exercise assignment!
For the NEAT activities calculations in the powerpoint questions are we just supposed to use the kcal/hour burned by walking and gardening?
And for the third question regarding how the calculated TEE in this assignment compares to the one from the dietary assignment, is there a number that we are supposed to get from And if so, where is it located? I am having trouble finding it.
Thank you so much!
Best Regards,
Answer: Good questions!  Thanks for your email!  Yes, use walking for walking, and gardening for basic roaming type tasks like cleaning, doing dishes, gardening, taking a shower, etc.  I think most of us get at least 3 hours of NEAT per day.
The TEE you calculate will be pretty close to the right value if you pick the correct level of activity.  You cannot compare it to anything because the value in is wrong.  We really need a better program but this is the one available to us that is free.
Hope this helps!  Joe Dixon
Hello Professor Dixon,   I have finished the exercise assignment and am ready to hand it in. I just wanted to clarify question 3 on the third page for the assignment (regarding TEE calculated on the website). I did not find a way to calculate the TEE on the website, so I just used the Calorie goal the program gives me and compared that to the TEE I calculated for the assignment. Is this acceptable? If not, I would really appreciate it if you could tell me how to find TEE on the program.   Thank you,
Hi, Don’t worry about this question because I realized too late that we are not using Eatracker because it was discontinued.  The Goal in is wrong.  I need to contact them and tell them this. I don’t see away to calculate your TEE using this site.   Joe Dixon

2.  Redesigning one of my PowerPoint Slides that you thought was confusing or poorly constructed – 5 Extra Credit points (So if you are doing very well in the class you do not have to do this assignment!).



Questions about the Exercise Assignment – April 12th Blog – Nutrition and Health – Spring 2020

Comments about the Exercise Assignment –

The Exercise Assignment is for the purpose of getting you to think about your Total Energy Expenditure (TEE) -that different things contribute to it. Also I want you to think about how much energy you expend when you do an exercise, and how many Calories are in certain snacks. Then there is a general question about NEAT in Question 1.

The Total Energy Expenditure (TEE) calculation is only a rough estimate.  Just like BMI is very rough, so is just using your weight in this calculation is very rough.  In some cases the number of Calories you calculate will be high for you.  Sometimes they will be low for you.

Here is another question concerning the Exercise Assignment from a student:


Hello and Happy Easter, I have a question about the NEAT portion of the assignment. I understand that Physical Activity is classified in levels, with moderate activity including walking and daily exercise. However, for the NEAT portion of the analysis questions, am I supposed to use the same number calculated for Kcals burned in physical activity? Or should I subtract the number I got for the exercise portion? Basically, isn’t NEAT supposed to exclude regular exercise activities? If you could clarify when convenient I would appreciate it. Thank you!   Stay well and enjoy your holiday,
Answer: Are you talking about question 1?  You are suppose to give a very rough estimate of your NEAT for the week and compare it to the Structured activity for the week.
Ask yourself – how many hours of structured exercise per week do you normally do? Take these hours and multiply by the Kcal for the structured exercise you do.  Then ask yourself, how many hours of NEAT per week do you normally do? Take these hours and multiply by the Kcal for walking or another NEAT activity like Gardening. You might want to break it down by activity. But in the end, you should have a rough estimate for weekly structured activity Kcal versus for Weekly NEAT Kcal. Which is greater?  Joe Dixon
