Questions from Students over the past few days – Sept 29, 2020

Important Question:   Good afternoon,  My name is ____________and I have completed the dietary assignment however I have a few questions. I followed the powerpoint as a guideline and did all the calculations for the assignment. On your powerpoint, you calculated the total fat in Kcal as well as the carbs and protein in Kcal. You then added up the amounts you got for each and showed that your calculated sum was less than the sum that was shown to you through the website we used. When I calculated mine, mine was higher than the value given to me by the website. Is this an error? How did this occur? Did I do my calculations wrong? If you could help me with this that would be so wonderful! I’m attaching my results below. Thank you for your time,    _________

Answer: Thank you so much for your email and for doing the assignment right away and thus you could ask such a great question.  I am not sure why there is a difference between your calculations and the total Kcal you came up with, and the value the program came up with.  In some  the calculation will be less.  I don’t understand why.  Nick’s explanations may be correct. 

Your calculation:  1996 total Kcal

Program: 1928 total Kcal

The difference is fairly small however.  1996 – 1928 equals 68 Kcal; And 68 / 1928 is about 3 – 4 %.

This is not worth worrying about. I showed the calculation the way I wanted it because I knew this would come up. Just do it as I showed in my powerpoint. Make sure you come up with the % contributions of Kcal from fat, protein, and Carbs

This was the perfect question as I will get many of the emails and I’m sure your question will help others. Joe Dixon

Question:   Hi Professor Dixon,   For question 2, is the answer really not all of the above? While I was taking the quiz, I was pretty sure that the energy for every single one of those examples originated from the sun. Specifically, I thought that the energy found in oil (due to deceased organic matter), plants (photosynthesis), meat (from eating animals that have eaten plants (photosynthesis)), and fat (from eating plants (photosynthesis) and/or eating animals that have eaten plants (photosynthesis)) has ALL ultimately originated from the sun.

Answer:  Thank you for your great email!  I gave everyone a point for the problems with QUIZ 2.  Your explanation for the answer to question #2 was right on.  I am just getting use to Canvas and I hope not to make mistakes in the future!  Joe Dixon

Question:   Hi Professor Dixon,   When I did all the obesity quizzes, it did not show me the quiz grade. Can you check which quizzes I did not get a 100 in so I can redo them to get full credit for it? I really enjoyed reading your book and I really like learning about Nutrition as I am trying to lose weight too! Those protein waffles you recommended the first class were very good recommendations!

Answer:  Hi,  Thank you for your email. Sorry to get back to you so slow.  I’m happy you liked the book.  I was wondering why you read it all at once and did all the questions at one time?  How long (hours) did it take you to read the book?  Did you find the questions helpful in getting the message of the book across? 

From some other letters, I thought it was evident how many questions were correct after someone took a quiz.  I’ll check on this!  Joe Dixon

Question:  Evening Professor, my name is _______, I am a student in your Nutrition and Health course 11:709:255:01. I know you’re still getting plenty of questions regarding the Obesity Explosion quizzes, but I have some since I’m a little confused. I understand they’re not due until early November and I have access to both the quizzes and the book. One thing I noticed is that the book is split into parts but the quizzes are labeled as chapters so I’m confused how the information lines up. Also, on the website for the quizzes, I only have access to 14 total quizzes when you said there are a total of 17 but only 15 need to be completed. Let me know how I can go about resolving this, thank you!

ANSWER:   Hi, Thank you for your email.   Yes, the quizzes are listed by chapter.   Chapters 1, 8 and 9 don’t have multiple-choice questions, so, in fact, there are only 14 quizzes in total.  So I changed the grading such that you have to do 13 / 14 quizzes to get full points for the Obesity Explosion quizzes.  I made a mistake in forgetting about chapters 1, 8, and 9 not having multiple choice quizzes.  Sorry about that.  Since it is self-study, and students don’t need to have their quizzes done until early November, I hope this OK with everyone.  I will check the quizzes Nov 1 and remind anyone who hasn’t completed the multiple choice quizzes.  Just as a note of information, chapters 1, 8, and 9 have essay questions attached to them, but I didn’t assign them to 255, so they don’t show up on the Website!   Joe Dixon

Question:  Professor Dixon,

Can we able to make up obesity quizzes? I kinda forgot to do them. Thank you, Student  –  Rutgers-New Brunswick

ANSWER:  11:45 AM (5 minutes ago) Hi, The Obesity Quizzes are self-study and are not due until early Nov.  Look at the most recent schedule of classes I sent out on Monday.   On Nov 1 I will check the quizzes and send out a warning to students who are behind in the Obesity Explosion quizzes.   Joe Dixon

Dear All,

If you have any questions about below – go through older blogs  or read letters from students to get information. 

Exam 1 –  Remember Exam 1 is Tuesday, Oct 6, 2020. It covers up to Chapter 5. I will put a review sheet for Exam 1 on Canvas on Wednesday, Sept 30th.

Lectures – I now only get a couple of emails about not being able to access the Recordings.  It most cases, it is an email problem or class registration problem – if you have problems contact Rutgers OIT immediately by phone – they will help you!

Lecture Quizzes –  Quiz 3 is now open and it needs to be completed by Wednesday, Sept 30th.  I will have the grades for Quizzes 1 and 2 updated today – it is very complicated and I am still learning!

Obesity Explosion Quizzes – You all should have the book (Email or Printed) and have registered for the Chapter quizzes on the Website.  This is self-study for now – try to keep up!  I have only received one recent email about trouble getting onto the Obesity Explosion Website.  Again, please read past Blogs if you still are havng problems.

Diet Assignment – I will spend a few minutes next lecture (Sept 30th) going over the Diet Assignment.  It is important that you read through everything so you can ask me questions.   It is on Canvas!

USDA graphing Assignment – Don’t worry about this – you have almost the whole semester to do it!

Later today, go to the Blog Site for Class 8’s Outline

Best,  Joe Dixon

  1. Remember, the second Lecture quiz is due on Canvas at 5 pm on Sept 23rd.  Don’t worry about question 10 – just answer it!  It is really a Poll question, but Canvas quizzes require an answer to be designated.  I will adjust the points in the grade book.

2. If you are still having problems getting access to the Website for the quizzes for “Obesity Explosion,” please read the previous posts about this.  Most likely the email with the Website code went to your spam folder. 

3. I am posting the Diet Assignment on Canvass today.  Please read through it several times.  I will go over it next class or the class after that.

Letters from Students – September 17, 2020

Tue 9/15/2020 1:19 PM

Letter: Good Afternoon Dr.Dixon,

I am writing to you concerning a few different matters:

1.) I absolutely LOVED your Obesity Explosion book, so much so that I finished the entire book and respective chapter quizzes in one day! One thing that I did notice, however, is that there is no Chapter 8 or 9 quiz for the reading.

2.) Do you have any other publications that are available for purchase? I would love to read more of your work!!

3.) Finally, when discussing protein sources in your book, you noted that peanut butter and hummus sandwiches on wheat bread are a personal favorite. Is this actually true? That combo seems rather interesting, but if it is actually tasty, I would be willing to try it as a pre-workout snack. Please confirm.

Enjoy the rest of your day! Best,

Letter: Sep 15, 2020, 3:50 PM (2 days ago) to me Hi Prof. Dixon,

I’m in section 1 of your Nutrition and Health class this semester, and even though it’s only been a couple of weeks, I’ve already learned so much useful life information from you.

One of the first lectures when you were talking about how all supplements are bad. Then you started talking about vitamins (especially B12) and you talked about that woman who was experiencing toxic effects from it like hair loss. You also continued to talk about daily value percentages and how they’re listed on every product. All of this got me a bit concerned, because I’ve been using a weight gain protein powder from GNC that seemed to be healthy and working well for a few months now. I’ve been using protein powder supplements for around 2 years now, so I double checked the nutrition facts of the ones I’ve used, and the current one I’m using.

To my surprise, I saw SO many vitamins that were WAY above their daily recommended value (Vitamin B12 was at 600% daily value I believe), and I’ve been taking this nearly every day. I felt instant regret that I didn’t know this sooner.

Everyone knows me for my long and thick hair which gives me a unique hairstyle (the ladies especially 😂), and within the past year I’ve been noticing it’s starting to lose its magic. I feel my hair not as thick as it used to be, and doesn’t feel the same when I run my hand through it. This use of protein powder is the only thing that could’ve affected my hair this much.

Immediately after I checked the facts, I threw out my protein powder. I used to use protein powder right after I work out, but as of last week, I’m opting for homemade grilled chicken which still has the great protein properties I’m looking for, along with assorted nuts.

I’m already noticing a positive difference in my hair and less bloating, and I can’t thank you enough. Who knows how long I would’ve kept using that nasty stuff from GNC. Forever grateful for your insights and I’m looking forward to what else you have to say!

Answer:  Permission was obtained to post this letter! Comments:  It seems a little soon to know definitively whether the supplement was causing a problem.  But as I said in class, this has happened quite a few times in past years!

Question:   Hello Professor,

I have been taking the obesity crisis quizzes on the platform and was wondering when the grades will reflect over on canvas. Thanks,

Answer:  I’m glad you got access.  How many quizzes did you take?  Did you need to do a retry?  Let me know your experiences?  I would love feedback!  Were the quizzes hard?  The grade will appear in the Canvas grade book when you finish 15 quizzes!   Joe Dixon

Follow-up: to me

Hello,  My grades were all hundreds and completed all 17. I had to retake them a couple times, but overall was great experience and fair quiz questions. Thanks,

Me:  Ok great!   I believe there were only 14 quizzes though!  My mistake!!

How did you like the book?  Why did you do all of them at once?  Joe Dixon


Attachments Sep 15, 2020, 5:27 PM (2 days ago) to me

Good Evening Professor,

I have a question about the obesity explosion book quizzes. I am taking them right now and I am unsure of how you will know if we did them or not. Are they connected to our email because I did not use my school email to sign up.

Also, it says in the syllabus that the quizzes are not graded but we can take them till we get 100%. Do we need to get 100% on them for full credit or can we miss a question or two and still get credit for the quiz?

Just to confirm that I am taking the correct quizzes, I have attached a screenshot. Can you let me know if that is the correct place/quiz?

Thank you so much for your help!



Hi,  Thank you for your email!!

Yes, you are in the right place!!  The upper Ribbon matches the Cover!!!!! Did you put your name in when you registered?  If so – it will be ok!  In fact, I can see your name in the panel above the quizzes for Chapter 4!  Can you tell from the website whether you got all the questions for a particular quiz correct?  If you don’t get all the questions correct, retry the quiz.  You can retry as many times as you need.  I will see your scores for every quiz in the gradebook.  If for example you miss 1 question here or there – I’m not going to take points off – that’s silly.  When you complete 15 quizzes out of 17 total, you will get full credit for the Obesity Explosion quizzes.  You won’t see your grade in Canvas until early November.  So please don’t worry about a few “Obesity Explosion” quiz points here and there.  Everyone will receive full credit if they complete 15 quizzes.  It is very much a self-study part of the course.  Of course, students can ask me questions about readings in the book.

Are there any other problems you are having?  Thanks for the great question! Joe Dixon

Class 5 – Nutrition and Health – Fall 2020 – Sept 17th – Chapter 4 of McGuire Text – Start Carbohydrates

Update for 255 – 9-17-2020   I am sending this both by Sakai and Canvas (and putting on the blog) because I am having problems with Canvas emails. If you get this email by Sakai but not by Canvas, please let me know. Remember, I really don’t know what is going on at your end. All of this is new to me too! For example, I didn’t know that I did not publish the Module for yesterday’s lecture. Therefore, you couldn’t see the slides for yesterday’s lecture. I had put them on Canvas last week and will usually put Powerpoints on Canvas by the night before a lecture. So if don’t have access to slides by the night before, please email me! Thanks!


Dear All,

1.  Go to the Blog Site for today’s Outline of Class 5

3. Remember, the first quiz is due on Canvas at 5 pm today. It is a very easy quiz – only 6 questions! Don’t worry too much about it! I will use it to make sure the grade book is working.

3. If anyone is still having problems getting access to the Website for the quizzes for “Obesity Explosion,” send me an email. I will forward your emails to the Editor I work with.   Remember, the “Obesity Explosion” quizzes don’t need to be completed until sometime in early November and you get unlimited tries on each quiz!

4. I am trying to keep up with emails but it is very difficult. If you are new student who just added the course, it is you responsibility to read through the syllabus, Schedule of Classes, and the grading rubric. Also, go to the blog and read through all the posts to see previous updates. If you haven’t heard back from me, send me another email.

Best, Joe Dixon

Class 4 – Nutrition and Health – Fall 2020 – Sept 15th – Chapter 3 of McGuire Text – On Zoom

Monday Update for Nutrition and Health – Sept 14, 2020

Some Important Announcements:

  1.  I now emailing to the Class through Canvas

2.  If you cannot access Class Recordings through Canvas and Zoom, you must take care of this immediately.  You need to call the Office of Information Technologies and they will help you!  I will not answer any more emails asking how you can see the recordings on Canvass-Zoom!

3.  The first Lecture Quiz will be published at 2 pm today and it needs to be completed by Thursday at 5 pm.

Here are very recent emails from students:

Question:  Mr. Dixon,   I know it is a little late to be asking this, but I am unsure where to find assignments for this course on canvas. I also haven’t seen any homework aside from reading the lectures assigned to me. Can you please clarify this for me if you have been giving us homework? Additionally, I am not sure if you have given us any quizzes yet since I couldn’t find them on the canvas website. Can you help me out here as well? Thanks,

Answer: Mon 9/14/2020 12:57 PM    Hi, I will start the first Canvas quiz today. Did you get the email I just sent out from Canvas? I don’t see the email that I sent out, and this bothers me. All my other emails were sent out through Sakai, which we are not using this semester.  We have not had any assignments or quizzes yet. There are still students adding the course! Have you had any other problems?   Were you able to see the lectures?  Thanks for your emails! I understand completely how you can get a little frantic about this kind of class.   Sincerely, Joe Dixon

Question:  Professor Dixon,   I was just wondering where I could access the recorded lectures for Nutrition and Health.  Thanks,

Answer: Do you have access to the canvas site for the course?   You must be properly signed up through Rutgers Canvas Zoom. They require an official email account. Please call OIT if you can’t see the recorded lectures on the Canvas site. Just Google them for the telephone number.    Joe Dixon

I will not answer anymore emails asking, “How do we see the recorded lectures?”  I have addressed this question several times!

Class 3 – Nutrition and Health – Fall 2020 – Sept 10th – Chapter 2 of McGuire Text – On Zoom

In today’s class we will continue going through Chapter 2 of the McGuire Textbook. But before that, I want to go over what I consider the Foundations of Nutrition. Then after the Foundations, and Chapter 2 slides, I want to discuss an important topic that is not in the Textbook – the Dietary Supplement Health and Education Act of 1994—commonly referred to as DSHEA.

Emails from Students:

Question: Hi Professor,  When will the post-lecture quizzes start? I have another class during you class time so I have to watch the videos at a later time each week.

When will the quizzes be starting?

How long will they be open for submission? Thank you!

Answer: Don’t worry about them yet – I will announce them when they are ready.  Have you been able to see the recorded lectures?

Question:   Hello, I was just wondering if there will be a descriptive study guide/chapter outline of what we are going to cover in the classes?  Thank You

Answer: Hi,  Thank you for your email.  I don’t have a descriptive study Guide/Chapter Outline for each class.  I sometimes have an outline in the first few slides of the PowerPoint Lecture.  I usually put an outline for each on the Blog Site.  I update the Schedule of classes as we go along. At this point you have the Schedule of Classes, the Blog site, the PowerPoint lectures, and the readings in the Textbook.  Adding one more thing would add another thing the students would have to check to follow along with the classes.  Then about a week before each exam, I give out a review sheet for the exam and it has what we covered.  Occasionally, I do not cover a topic and then it is not in the Review sheet.  In what form would a study Guide/Chapter Outline be that would be helpful to you?  I have been thinking about doing one, actually.

Sincerely,  Joe Dixon

Question: Hi Professor Dixon, My name is ­­­­­­­_____________, I am currently in your Nutrition and Health class and I am confused as to what material we need for the class this semester. Reading through your emails I noticed that we do not necessarily need the Nutritional science book. But we do need the Obesity Explosion book as well as the access code. Once I purchased the Obesity Explosion ebook with the access code from Kendallhunt, I was able to access the ebook but when logging in using the access code for the homework it said the class was not set up yet? Also, is there any other books/material that we need for this class?   Thank you,

Answer:   Hi,  Sorry to take so long to get back to you.  I am laughing because somewhere you got the impression that you do not need the “Nutritional science book.” I do recommend you get the McGuire textbook for background material that I can’t get to in the class. 

The site for the Obesity Explosion that you get access to with your code will be ready soon.  I will make a major announcement when it becomes available.  It was just finished last week and I just got access to it myself on the Friday before Labor Day.  I am proof reading the questions now!

There are no other books you will need for this class.  Thank you for your email!

Sincerely,  Joe Dixon
