Food, Science, and the Human Body

Rated 5 out of 5 by from Excellent course! Very fascinating course. It gives you a different perspective on foods, diets and their origins all the way back to our prehistoric ancestors. A different view of food and diet, not just a standard "this is good and that is bad food for you". Definitely makes me look at nutrition in a different way. I will run through the entire course a second time.

Rated 4 out of 5 by from A good synthesis for the beginner The lectures are well organized and presented. As she says near the beginning and a few times along the way, the subject overlaps many disciplines, and she brings them together quite effectively. I took the audio course; video might be preferable if it includes a visual presentation of many of the unfamiliar names and terms involved. I appreciated her subtle sense of humor. She uses the word "actually" much more than necessary, apparently to mean something like "I'm telling you something you might find surprising or unexpected"--which indeed she does do, and often enough. Did you know that bananas don't grow on trees? (Actually, I did, long ago, but had forgotten.)

Rated 1 out of 5 by from Too preachy for me What a disappointment! The professor was obviously reading the text and there was far too much "so-and-so from this-university" over and over. Really off-putting. Also did we really need the "disclaimer" at the end of every single lecture? Are we elementary school students? And the last few lectures really grated on my soul -- instead of looking for ways to feed muliti-billions, why is there never any discussion on decreasing the population of the world? And do we really need to be lectured using the United Nations? Finally (and this is just being picky) she enunciated so many words (and mispronounced many) so why did she say "twenny" for twenty? Okay, so that might be stretching my critique but it was annoying. So other than my annoyance at the professor, the first half or so of the course was quite interesting (and this from a nutrition minor many moons ago, who also worked at a major university for a nutritional biochemist) but much of the second half was just annoying. I found I could not quite finish the course. Definitely a "miss" as far as I am concerned.

Rated 4 out of 5 by from Interesting but needs more. I am struggling with my ratings on this course. It is interesting and well presented but needs more details. It appears to me the subject is too big for 'only' 18 hours. I'm not sure if I should recommend this course or not. For an overview of how humans and diet evolved, the pros and cons of various diets, and the politics of sustainability the course works. But, as an overview only. I needed (at least wanted) more detail on how the various chemicals in our bodies interact with each other. In the context of only 18 hours it is probably as well done as possible. I felt I needed a preliminary course in human chemistry . The professor uses a lot of technical terms that are not explained in detail nor is there a glossary to explain them in the Guide Book. I took this course with "Food: A Cultural Culinary History". I did not give that course my highest ratings. I have come away with the feeling the courses together have a lot of unrealized potential. "Cultural Culinary" better organized and taught on a higher academic level; and this course with some addition of the body's chemistry and how various food elements (vitamins, proteins, bacteria, etc.) interact with each other, genetic predisposition, and the gut biome. I'm happy I took both courses; but seems like there is so much potential to put the two courses together with more detail to make a really great course. That is a lot of work, I know.

Rated 4 out of 5 by from Food for Thought Food, Science, and the Human Body strikes me as a very important course for personal and public awareness. There is much in its content which I will ponder further and which I will certainly want to watch and study more than once. As a presenter, Dr. Alyssa Crittenden spoke pleasantly and fluently, though occasionally (in my opinion) too rapidly. She is obviously a person with impressive multi-disciplinary interests and competencies. I appreciated her erudition and her sophisticated vocabulary, though I would have liked her to define even more of the terms, both scientific terms and slang or colloquial words, used in her lectures. I admired her forthright, non-judgmental, and professional manner when discussing controversial and/or potentially disturbing material. After preparing most of my present review, I had a look at how other purchasers of the course had commented about it on The Great Courses website. Frankly, I was amazed that a few seem to have felt that they had been reprimanded by a moralistic instructor. While I did note several problems with this course, didactic condescension on the part of the professor was not among them. I thought she discussed topics evenhandedly and maintained a matter-of-fact tone throughout. She abundantly identified the governmental, scientific, and/or international agency sources of the information she presented and seldom expressed unsupported personal opinions. Even when some of the data she had to share might have made me feel uncomfortable or even defensive, it was never she herself who caused that. Her Lecture #33 about “World Poverty and Undernutrition” provides a good example: much of what was shared therein was grim, and ways that the world or individuals might responsibly address crises were discussed; however, I never felt Dr. Crittenden was pushing her own viewpoints down my throat or nagging me to do more to help than I might already be doing. Where relevant, she shared optimistic news in addition to reporting food-related problems. Also, whenever discussing dietary choices or food politics, she consistently described varieties of attitude that different people adopt, and why they might tend to favour those, without being bossily prescriptive. I was disappointed that sometimes statements were left unexplained, were ambiguous, or were simply erroneous. I will give three examples (one for each type of “glitch”), though I could cite one or another from each of the thirty-six lectures: 1) At one point, both the DVD episode and the course book included a statement about humans eating “many tubers, such as potatoes, sweet potatoes, yams, and summer squash,” and that came despite tubers having just been described as underground features of plants—if there was a logical reason to put summer squash in the “tuber” category, it was never explained. 2) During Lecture #11 about the history of the spice trade, numerous references were made to events in widely separated centuries, and the ambiguity that bothered me here was that it wasn’t always specified which references were to centuries BC and which to centuries AD. 3) In Lecture #17’s discussion of wine, it was said that 15% of the world’s cork production was used to stopper wine bottles and that “the remaining 75%” went into shoes, baseballs, musical instruments, etc.—clearly, these percentages do not total 100%. If these lectures were delivered from a prepared teleprompter script, as I suspect was the case, then perhaps that script should have been better proofread before the lectures were recorded. Any course may forgivably include what I’ve called glitches. My concern here is that there was a large sum total, detracting from overall educational quality. Given that the title of the course admits such a broad scope for inquiry, I can’t claim that Dr. Crittenden didn’t “stick to the topic.” I will say that I personally would have preferred a tighter focus, even if the course had to be shortened; I then likely would have found the instruction even more effective and memorable than I did. I felt the professor’s best lectures were excellent indeed, including the opening nine when she was particularly describing her own research. Some of what was surveyed during other lectures, though, felt more to me like digressions or tangents than germane essentials. Yes, I did need to be informed about crucial aspects of the world’s food trade history, about diets and diseases, and about both undernutrition and overnutrition. No, I don’t think extensive details about soda pop, foods used as recreational drugs, and the obsessions of some people who swallow non-food items enriched my learning experience. Instead of shortening the course, it might have been even better simply to spend less time scrutinizing the less important topics. I would have welcomed discussion devoted instead to such things as milk in the adult human diet, government-issued food guides, controversies over the power of lobby groups, and the politics of school lunch programmes. In general, I was disappointed by the set of visual accompaniments to these DVD lectures. Some photos and other illustrations seemed to fit poorly with what was being said when they came on-screen; some that did fit were unfortunately repeated again and again. When a multi-storied garden construction was discussed at length during Lecture #33—not a construction especially easy to visualize—there wasn’t any illustration, either on-screen or in the guide book, at a point that seemed to “beg” for at least a sketch. A drawing of a naked man did indeed accompany a discussion of the difference between heme iron and non-heme iron in Lecture #29—it was not anatomically correct due to missing genital organs! Such prudery in a university-level science course? Despite the rather extensive critique I have felt led to give of Food, Science, and the Human Body, the course still does rank as “good” when I compare it to courses I have attended “live.” I am not sorry I purchased it, I do recommend it despite some reservations and, again, I consider it a very important course! In its favour is that it can be used as a companion course to Dr. Ken Albala’s excellent Food: A Cultural Culinary History, available from the same catalogue.

Rated 5 out of 5 by from A Fascinating Exploration Into Food & Our Bodies We all have to eat but how much do we know about the history of this essential activity and the science behind our foods and our bodies. Dr. Crittenden starts us out with our Hunter Gather ancestors and brings us up to the most modern innovations in food production and animal husbandry that have promise to feed and sustain a world of 10 billion. I enjoyed every lecture including the discussions on human digestion and how a cow processes its food. I learned a lot from this course and would recommend it to anyone. I had heard of bio-meat and shipping container farms but Dr. Crittenden provided a much more detailed description of these techniques.

Rated 1 out of 5 by from not what I expected I wanted a history of food but she spends most of her time talking about trade. After the first few lectures the course becomes a advertisement for fair trade and the professor's social ,economic and enviromental platform. The science is mostly trade and economics and very little how food effects the body

Rated 5 out of 5 by from One of the Teaching Co's best courses This is one of the Teaching Co's best courses--remarkably objective and informed about early human diets and what would be healthy for modern humans. It's also fascinating in its coverage of everything from the history of chocolate to the effect of mothers' diets on their children. Alas, when I mentioned a criticism of some diet fads the review robots gave me a Profanity X and wouldn't allow this--there was no swearing, just a scientific assessment, so I didn't know what to change and had to settle for this.

Rated 2 out of 5 by from Finger wagging lectures I generally enjoy the Great Courses very much. I bought this one expecting a scientific analysis of our food needs and habits. While there was much of that, the professor also included stern, schoolmarmish diatribes on such things as the evil practices of chocolate farming. I could do without the attitude.

Rated 4 out of 5 by from Holy Cow! Really enjoyed this course, so I think other foodies will also like it. Time went by really fast. If you ask me, it’s a welcome complement to Ken Albala’s course, Food: A Cultural Culinary History and Nutrition Made Clear (Roberta Anding). This new course is inter-disciplinary, covering culture, anthropology, food, history, the human body, politics, etc. It’s got everything from soup to nuts, so I found it engrossing. Unfortunately, it’s short of 5 stars because there were a few lectures in the middle that were informative but a little soft for typical TGC viewers. Off the top of my head, a handful of lectures from 10-20 could’ve been beefed up. The course is chock-full of interesting factoids (e.g. how many seeds in a pomegranate, history of Halloween, pica, etc.). The ending lectures on the politics of food production were definitely food for thought. Regarding land use data in Lecture 34, a colorful chart/graphic would’ve made a bigger impact than %. But the cow graphic explaining the enteric fermentation process is classic. Whoever made that one—take a bow and ask for a raise. The Guidebook is meaty, weighing in at 368 pages. The bibliography has a lot of entries worth following up on. However, there were probably a half dozen typos that I spotted. TGC, may I introduce my good friend, Spellchecker? Apologies for the eye roll—recent Guidebook typos are my pet peeve. Your editor isn’t a bad apple, but mistakes were made. Professor Crittenden did a good job presenting. She’s a competent speaker who’s comfortable in front of a camera. In a nutshell, it was worthwhile. I’ve been following up on some of these topics online. Unrelated: In the future I’d relish a course on food science.

Rated 5 out of 5 by from Very Interesting Subject I have a long history of wanting to learn more about this subject. I have consumed books on food history and human eating habits. This material from The Great Courses covers all the aspects of the human experience with food and what it has done for us and to us. Very worthwhile course.

Rated 5 out of 5 by from Appropriate title. This course covers food science with an emphasis on the evolutionary biology and the history of food. As a nutrition scientist myself, I found the lectures both informative and innovative. The lecturer was enthusiastic about the material and kept me pleasantly focused. Whatever your main field of interest, I believe you will find this course will change your understanding and appreciation of your most intimate contact with your environment, namely when you eat it.

Rated 5 out of 5 by from Unique Approach to food This is an unusual presentation for the topic; but, it is very good because the approach is both practical and useful to the student of food products, as well as to the customer. Also, certain elements such as spices, are presented in easily understood formats.and necessary details.
