The U.S. Department of Health and Human Services provides a sample week-long menu that fulfills the nutritional recommendations of the government. Canada’s Food Guide is another governmental recommendation.
Federal and state governmental organizations have been working on nutrition literacy interventions in non-primary health care settings to address the nutrition information problem in the U.S. Some programs include:
The current DRI values differ from those used in nutrition labeling in the U.S. and Canada, which uses Reference Daily Intakes (RDIs) based on RDAs from 196
Sometimes overlooked during his life, James Lind, a physician in the British navy, performed the first scientific nutrition experiment in 174 Lind discovered that lime juice saved sailors that had been at sea for years from scurvy, a deadly and painful bleeding disorder. Between 1500 and 1800, an estimated two million sailors had died of scurvy. The discovery was ignored for forty years, after which British sailors became known as “limeys.” The essential vitamin C within citrus fruits would not be identified by scientists until 193

Studies of nutritional status must take into account the state of the body before and after experiments, as well as the chemical composition of the whole diet and of all material excreted and eliminated from the body (in urine and feces). Comparing the food to the waste can help determine the specific compounds and elements absorbed and metabolized in the body. The effects of nutrients may only be discernible over an extended period, during which all food and waste must be analyzed. The number of variables involved in such experiments is high, making nutritional studies time-consuming and expensive, which explains why the science of animal nutrition is still slowly evolving.
Protein deficiency and malnutrition can lead to variety of ailments including mental retardation and kwashiorkor. Symptoms of kwashiorkor include apathy, diarrhea, inactivity, failure to grow, flaky skin, fatty liver, and edema of the belly and legs. This edema is explained by the action of lipoxygenase on arachidonic acid to form leukotrienes and the normal functioning of proteins in fluid balance and lipoprotein transport.

As for the seeming contradiction, the editor apparently feels the text is saying that fortifying the yeast removes iron and that this doesn’t make sense. Maybe, maybe not. The reliable source does say that fortified yeast provides less iron. Several possibilities: The source may be wrong (we’ll need a better source correcting this if you believe this is the case). The act of fortification may somehow remove iron. Fortification may make the iron less bio-available (i.e. just as much iron, less of it can be absorbed by the body). Fortification may displace the iron (2 tablespoons of fortified nutritional yeast is less than 2 tablespoons of yeast plus whatever is added (for a total of 2 tablespoons)). A serving of nutritional yeast is ~ 16 g. 720% of the daily value for riboflavin is roughly 1 g. If we fortify nutritional yeast with just the riboflavin, we would have 15 g of yeast and 1 g of riboflavin.
