Class 24 – Nutrition and Health – Spring 2020 – April 17th – Chapter 13 – Trace Minerals
There is a Live On-line Lecture during the official class time (12:35 pm) today. Please go to the Sakai Meetings Tool and you can join the meeting and see the lecture. The lecture will also be recorded!
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

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?
Here are the New AI Values for Potassium:

I am extending the due date for the Exercise Assignment to Friday, April 17th, at 5 pm.
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 myfoodrecord.com? 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 myfoodrecord.com 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 myfoodrecord.com 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 myfoodrecord.com 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

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

Tuesday Blog – Update on Class and Exam 2 – April 7th – Nutrition and Health – Spring 2020
Update on Class, Exam 2, and Assignments
I will be uploading grades to the Sakai Grade book today and tomorrow. The grades in Sakai are the official grades. If there are any problems – please email me at joedixon709255@gmail.com
Exam 2 – I just downloaded from TopHat the grades from Exam 2 – The mean was 92% and 285 students have taken Exam 2 with 16 still needing to take it. I am really amazed how many took the exam and the grades are very good! I have received emails from students who are ill, working overtime, and with Internet problems. There are some students who are now back home in their own countries – including China and Korea! When you think about it, this is an amazing time, and all of you need to be commended for doing your best to keep up and for staying in contact. Therefore, I will open Exam 2 back up again and I hope students who have not done so can take the exam when they are ready to do so.
Quizzes – There are still many people who have not yet completed the quizzes for Exam 2 – Lipid Quiz 1, 2, 3; Metabolism Quiz 1 and 2; and Energy Balance Quiz. When you can, try to take them so you get the quiz points. They are still open right now.
Assignments – Please go to the Blog Site to see comments about these assignments!
Diet Assignment – 242 have uploaded their Diet assignment – I have heard that there were some problems uploading it. Please get your diet assignment in when you can. It seems like this assignment will take a long time, but actually, it can be done in 2-4 hours. But I realize many of you are not in the best place (either physically or composure) to complete such an assignment.
Exercise Assignment- 19 have uploaded it! There are some questions from students about this assignments coming in now. This assignment does 3 things: 1) Allows you to calculate your daily Total Energy Expenditure, 2) gives insight into how much time is takes to burn Calories; and 3) Give insights into NEAT and how important it is.
Don’t forget the Live lecture today at 12:35 pm!
Class 21 – Nutrition and Health – Spring 2020 – April 7th – Chapter 11 – Start Fat Soluble Vitamins
Last time we did the water soluble vitamins. Today we will start Chapter 11 – the Fat Soluble Vitamins. In general, the Fat Soluble vitamins are more complex and harder to learn about. Please read the Chapter and tune into the live Lecture tomorrow (Tuesday) at 12:35. The Lecture will be recorded but will not be available until the next day.
There will be a Quiz for the Water Soluble vitamins put on TopHat tomorrow morning (April 7th)!
Monday Blog during the Pandemic – April 6th – Nutrition and Health – Spring 2020
By now, Monday, April 6th, most of you should have finished Exam 2 and the Quizzes. Also, most of you should have submitted the Diet Assignment. If you have trouble getting Internet or if you are working nonstop, get your assignments in when you can. I realize there is a great deal of suffering out there. I do not want to add to it. But for many of you we need to go on so that we can get the course in.
Here are some important Points:
-
Use the Course Blog as an Epicenter for the Course. Especially read through the questions that students submit.
2. If you have to email me, email me at: joedixon709255@gmail.com Your emails get lost in my Rutgers email. As some students can attest to, sometimes I email you back in minutes using the gmail account.
3. Tomorrow there will be another live lecture at during regular class time at 12:35 pm. Go to the meetings tool in Sakai.
Exercise Assignment:
Now you should be working on the Exercise Assignment. Some students tell me they do the Exercise Assignment in less than 2 hours. The Exercise Assignment is fun and informative.
On page 1 – You calculate your Total Energy Expenditure (TEE). This is the total amount of Calories you burn each day. The number calculated by myfoodrecord.com is wrong!!!! It is not your total energy expenditure.
There is a common error that students make in this assignment. It is illustrated by the emails below and the figure underneath them. Also, take note of a problem in Question #3.
Questions on April 6th, 2020
Sun 4/5/2020 1:14 PM. Hello Professor Dixon, I had two quick question regarding the exercise project that was assigned. …..As well as, when subtracting the energy expenditures from the BMR, are we suppose to subtract the energy expenditure value from the BMR each time. For instance, for biking the energy expenditure is 345 Kcal/hour so would I do 1167( my BMR)- 345 to get my actual kcal burned and then to calculate for another activity would I also do for instance swimming is 331 kcal/hour, so 1167- 331 and I would use the 1167 and not the answer that I got from the previous activity? Thank you so much for your help,
Answer: Hi, The number you used at the top of the 2nd page is wrong – it should be 49 Kcal per hour – everything is per hour!! You used the per day BMR! See Figure below!
When you subtract this from the activities Kcal per hour, you should get just a little lower number. You subtracted the energy expenditures from the BMR? Does that sound right to you?
Where did you get 641 Kcal from? Your time calculations look ok but make sure you use the correct number in the denominator. Joe Dixon
Hi Professor Dixon, Oh I completely understand the mistake I made. Thank you, for letting me know. Also, the 641 was for an activity I was going to use but then changed. I forgot to change it on my sheet. Also, for the part 3 questions, for number 3, what is the Eatracker program that you are referring to? Thank you,
Answer: Hi again. The Eatracker program mentioned in question 3 of the Exercise Assignment was the program we used last semester that was discontinued in December. The total number of Kcal calculated from myfoodrecord.com is wrong! So there is nothing to compare it to. The value for total energy expenditure (TEE) you calculated on the first page is a pretty good value! Joe Dixon
