Board Presentation on 9-18-2019:
On the board I reviewed the reason I discussed the mechanism of fire and how it relates to energy in foods and how energy is conserved in humans. Obviously, there is energy in the bonds of the fuel for a fire. That energy can be measured in a bomb calorimeter as was performed in the late 1800s by Rubner and Atwater. Then experiments showed that energy is conserved in humans such that if 2,500 Kcal are eaten, then that 2,500 Kcal can be measured and accounted for in the human who ate it. One of the ways to do this is by measuring the amount of oxygen consumed by a human who is performing some kind of work or activity. Thornton realized that each liter of oxygen consumed was equivalent to about 4.7 Kcal (This is called Thornton’s rule).
In the second panel, I show the calculations you can make using the Atwater numbers. Also, the average American diet consists of 50% of Calories from carbohydrate, 35% of Calories from Fat, and 15% of Calories from Protein. Of course, individuals can have much a distribution much different than this.

The Opioid Crisis and How Drug Companies Tied the Hands of the Food and Drug Administration reminds me of how Supplement Companies tied the Hands of the FDA in the early 1990s.

Note about Order of Topics:
I follow the book very closely throughout the semester. The first two chapters of the book are fairly light and concern general information about Nutrition and how the Dietary Standards (Dietary Reference Intakes (DRIs)) were created and why. I add some information about the Foundations of Nutrition, which were developed in the late 1800s and early 1900s. Much excellent Nutrition research was done during these periods of time. One of the problems the “Media Nutrition Experts” have is that they do not know about the early research and thus have missed the most important fundamental findings in Nutritional Sciences. I have selected what I call the Three Foundations of Nutrition. These topics or breakthroughs were not the only research performed by the early researchers, but I consider them the most important. Without these three foundations, the rest of nutrition research would have been difficult to complete.
On the following Synopsis of the course, I highlight what portion we are doing right now and where we will head next.
Class Survey Conducted the First Day of Class – It is important for me and you to know who is in the class. On one hand it, is a challenge to teach such a diverse class. On the other hand, it is fun and I enjoy the diverse backgrounds of everyone in class.
Class 1 – Nutrition and Health – Fall 2019 – Welcome to Class
Welcome to the Class:
I wanted to say I am looking forward to class this semester. Last semester I added TopHat to the class so as to get immediate feedback and to better track attendance. The response was amazing – every student I talked to liked using TopHat. In order to makeup for some of the extra money you need to spend on TopHat, I went back to using primarily the solid Textbook, which you can probably get used for a very small amount. There must be hundreds on campus somewhere. You can still order the on-line version of the book if you prefer that. In order not to need the online version of the book, I found a free diet analysis program that is extremely easy to use and can be done from your phone. So we will no longer use the Textbook diet analysis program.
I have a blog for the course that can be accessed directly or through TopHat. The name is: https://howtocureobesity.com
On the blog I put the outline for the day’s lecture and some interesting tidbits I find here and there. If someone asks me a good question (which almost all are), I will answer it on the blog.
And finally, I use Sakai for resources, announcements, and for its gradebook.
Looking forward to a fun and productive class!
Joe Dixon
