In this unit, you learn about macronutrients: protein, carbohydrates, and fats. Many people have suggested that focusing on one macronutrient at the expense of others would be a superior diet. Thus, we have high-protein diets, high-carbohydrate diets, and high-fat diets. On the flip side, we also have low-fat diets, low-carb diets, and so on. In addition to these, there are other versions such as a gluten-free diet (which is necessary for those truly allergic to wheat), a vegan diet, a raw food diet, and even a blood type diet that is based on particular blood types. Reflect on your eating habits. Which type of diet do you prefer? Why do you prefer this type of diet to other diet options?
