I am taking a basic nutrition class at the Community College of Denver as a pre-requisite for nursing school. Each week we reflect on what we learned the week prior (yes, kind of high-schooly). My professor is a naturopathic doctor (ND) so generally plant-centered, but she was on vacation so we had a guest lecturer (Dr. Daly). My last note to my professor follows, with comments in brackets.
Last week was our first week of class with Dr. Daly. As a vegan, it is interesting but occasionally frustrating to absorb mainstream nutritional information because it does not always fit with my worldview. I vented some of my angst over this issue with some of my vegan friends last week as we prepared for a big public dinner [CHOMP]. While I recognize that it is important to get nutritional information from multiple sources in order to ensure a balanced “information diet,” I must ensure for the sake of my learning that I can build this knowledge in a way that meshes with my veganism. Vegan diets are still far from mainstream. I was thinking about this especially as I reflected on the many iterations of the Food Pyramid, which is now My Plate, a dish divided into four sections (fruits, grains, vegetables, and protein) with a place at the corner for dairy. In class, I asked Dr. Daly what components of dairy were beneficial and how someone who doesn’t drink dairy might meet those requirements. As an older, Caucasian person, it is understandable that Dr. Daly wouldn’t challenge the setup of My Plate, but in other ethnic/cultural groups such as Chinese people, or vegetarian Buddhists, eating dairy or large amounts of meat might not make as much sense. I searched for an alternate My Plate and found the following, vegan version, which explicitly names protein as “legumes” so that users will understand well that adequate protein can be gotten from plant sources. The dairy at the corner is replaced with water, because calcium can be gotten from leafy green vegetables.

Dr. Daly introduced the concept of nutrient density, which is the idea that foods with more nutrients per calorie should be favored in our diets. She gave us an assignment to plot the relative nutritive value of four of our favorite foods relative to their calorie content. I chose blueberries, kale, sweet potatoes, and chia seeds. According to SELF Nutrition Data, which boasts a wealth of information for thousands of foods (depicted in a visually pleasing and understandable way) these foods excelled for various vitamins and minerals. I was glad to learn this, but I think that these nutrient charts can be misleading. First of all, because a usable nutrient chart can only include five or perhaps ten nutrients, the selection of those particular vitamins and minerals will have an enormous influence on foods deemed “nutrient dense,” because every food has a different composition. Furthermore, because the nutrition field is still developing, we may not know to measure various beneficial components that may be present in whole foods but that we may not have the tools to measure or recognize. On the whole, though, I think the nutrient density concept is a useful one, and if I had more courage, I would show Dr. Daly the following “nutritarian” Food Pyramid by Dr. Joel Fuhrman.

I will be sure to bring in the Color Me Vegan book that I was telling you about, that is so focused on eating whole, colorful plant foods to increase phytochemical intake and improve health. It is important for me to get a dose of mainstream nutritional information, so I have a sense of generally accepted knowledge, but this experience reaffirms that general health, rather than nutrition, is the field for me. I think that devoting myself to nutrition would be too frustrating, but it is good background to have. A full-time vegan diet may not be feasible for many people, but my knowing this information will help me counsel vegans on how to include more plants in their diets. After all, in the words of the American Dietetic Association, “appropriately planned vegetarian diets, including total vegetarian or vegan diets, are healthful, nutritionally adequate and may provide health benefits in the prevention and treatment of certain diseases.”
