Each level of reflection is structured to parallel Bloom's taxonomy. (See installment 1 for more on the model). Assume that a teacher looked back on an lesson (or project, unit, course, etc) they have just taught.
Vitamin E deficiency is uncommon in adults but can occur in people whose diets are high in polyunsaturated fatty acids, which increase vitamin E requirements, and in people with vitamin E malabsorption, which impairs red blood cell (RBC) survival. Serum alpha-tocopherol levels are below 0.5 mg/dL in adults.
Polyunsaturated fats are where omega fatty acids, such as omega-3s and omega-6s, are found. There are many different kinds of saturated and unsaturated fatty acids, and science is still trying to understand how they all function in the body. For a list of saturated fatty acids, see here.
