What is nutrition?


Hi, this is Neily on Nutrition. Thanks for tuning into my continuing series during National Nutrition Month. Today I want to talk about: What is Nutrition. I’ve been adjunct faculty for nearly twenty years at a community college teaching principles of nutrition. And I think sometimes my students register for my class thinking “oh nutrition, how hard can this be,” thinking maybe it’s a blow-off class. Well, how quickly they find out that it’s not a blow-off class. Let me tell you what nutrition is not. Nutrition is not an opinion, yet many people have an opinion about nutrition. Everybody eats so everybody seems to have an opinion. I certainly did and I think that’s what sent me back to school to study nutrition and get my Masters in it. I love what to my colleague, registered dietitian/ nutritionist, Sally Hara said many years ago, “nutrition is a science, not an opinion.” How true is that. Nutrition is a science. It’s built upon the foundation of many other sciences including Anatomy and Physiology, Biology, Chemistry, and even Biochemistry. Yes, nutrition is Biochemistry, the study of the chemical processes within the body. Nutrition is a very young science actually. The first vitamins weren’t discovered until the early 1900’s. The first controlled experiment was back in 1747 and during this month we’re going to learn about that. It was actually a discovery of the cure for Scurvy, but it wasn’t until nearly two hundred years later that that actually vitamin C in the early 1930’s or absorb acid was discovered. Anyways, that’s just one of the things we’re going to be talking about, but what nutrition is… it’s a science of foods and and and and what we eat and it’s about the digestion, the absorption, the transport, the metabolism, the utilization, the excretion of the nutrients, and and in relation to also our health, and relationships and implications of disease. It’s also about the social, the economic, the cultural, and psychological implications of food and eating. But we’re going to focus mostly on the science of it and the about the what’s happening in the body. I want you to think about, what did you have for breakfast and what was the process of that food? What I had for breakfast… I had for breakfast, I had had walnuts, blueberries, and some whole grain cereal mixed into some Greek yogurt. So what happened to that food? And what’s happening within the body right now? The protein in the Greek yogurt and the little bit from the walnuts those are breaking down into amino acids. The fat in the walnuts are breaking down to fatty acids and glycerol molecules. The carbohydrates in the whole grain cereal and the blueberries ultimately will become glucose, and I want to talk to you about that and the processes within the body. So stay tuned this month, I hope you enjoy this series and learning a little bit. Tomorrow, I’m going to talk about the six classes of nutrients. So stay tuned, thanks for watching Neily on Nutrition, and leave a comment, what are you thoughts about what nutrition is? Did you realize that it’s a science and such a young science? Again, thanks for watching Neily on Nutrition and we’ll see you tomorrow in the next video.
