The Textmap is targeted toward intermediate-level, nutrition course and is divided into 13 chapters with sections and subsections. These are numbered in such a way that the first number represents the chapter. The Textmap also contains links to articles, videos, and animations in Web Link boxes. These can be clicked to open the link, and urls for these resources are also provided at the end of the section or subsection.
1: Nutrition Basics
The field of nutrition is dynamic. This means that our understanding and practices are constantly changing and being updated. Some of nutrition’s dynamic nature may be due to the fact that nutrition, as a discipline, is relatively young (many vitamins weren't isolated until the 1930s) compared to many other scientific fields. New research is always being conducted and the findings are continuously being reported to the public.2: Macronutrient Structures
As you have learned, there are three energy-yielding macronutrients: carbohydrates, proteins, and lipids. This chapter goes more in depth about these major dietary components.3: Macronutrient Digestion
You probably do not think too much about what actually happens to the food you eat. This section will describe in depth how what you eat is digested. The desired end result for the learner will be an integrated understanding of the process. This will require higher levels of thinking, but will prove to be well worth it in the end.4: Macronutrient Uptake, Absorption and Transport
The term absorption can have a number of different meanings. Not everything that is taken up into the enterocyte from the lumen will be absorbed, so the term uptake refers to compounds being transported into the enterocyte. Absorption means that a compound is transported from the enterocyte into circulation. Under most circumstances, compounds that are taken up will then be absorbed.5: Common Digestive Problems
Before moving to metabolism, we are going learn about some common digestive problems.6: Macronutrient and Alcohol Metabolism
Now that we have digested, taken up, absorbed, and transported the macronutrients, the next step is to learn how these macronutrients are metabolized. Alcohol is also included at the end of this chapter, even though it is not a macronutrient.7: Integration of Macronutrient and Alcohol Metabolism
Understanding the different metabolic pathways is an important step. However, an integrated understanding of the interconnectedness and tissue specificity of metabolism is where this knowledge really becomes powerful. To this end, we will first cover how the different pathways feed into one another and then talk about the metabolic capabilities of the different tissues in the body. We will then discuss what happens metabolically during different conditions or when consuming certain diets.8: Micronutrients Overview and Dietary Reference Intakes (DRIs)
Micronutrients consist of vitamins and minerals. In this chapter, an overview of vitamins and minerals will be presented followed by a description of the dietary reference intakes (DRIs), which are used as benchmarks of micronutrient intake.9: Antioxidant Micronutrients
This chapter will describe what antioxidants are and then discuss the three major antioxidant micronutrients: vitamin E, vitamin C and selenium.10: Macronutrient Metabolism Micronutrients
All but three of these will be covered in this section. Vitamin B12 will be covered in the one-carbon metabolism chapter, vitamin C was covered in the antioxidant chapter, and magnesium is going to be covered in the electrolyte chapter. We're left with iodine, manganese, and many of the B vitamins. We'll cover the 2 minerals followed by the B vitamins.11: One-Carbon Metabolism Micronutrients
Three B vitamins are involved in what is known as 1-carbon metabolism. This is the movement of 1 carbon units, generally methyl groups (CH3). It is similar to the movement of the amino group that occurs in transamination. Folate, vitamin B12, and vitamin B6 are the B vitamins involved in 1-carbon metabolism.12: Blood, Bones, and Teeth Micronutrients
This chapter is a collection of vitamins and minerals that are involved in the structure or function of blood, bones and teeth.13: Electrolyte Micronutrients
In this chapter, electrolytes will be explained before learning more about the 4 electrolyte micronutrients. Then, hypertension will be discussed, along with the impact of these micronutrients on the condition.
