This is just a quick post to highlight two recent papers by the economist and fellow health writer Matt Metzgar.
The first paper is titled "The Feasibility of a Paleolithic Diet for Low-income Consumers", and is co-authored by Dr. Todd C. Rideout, Maelan Fontes-Villalba, and Dr. Remko S. Kuipers (1). They found that a Paleolithic-type diet that meets all micronutrient requirements except calcium (which probably has an unnecessarily high RDA) costs slightly more money than a non-Paleolithic diet that fulfills the same requirements, but both are possible on a tight budget.
The second paper is titled "Externalities From Grain Consumption: a Survey", with Matt Metzgar as the sole author (2). He reviews certain positive and negative externalities due to the effects of grain consumption on health. The take-home message is that refined grains are unhealthy and therefore costly to society, whole grains are better, but grains in general have certain healthcare-related economic costs that are difficult to deny, such as celiac disease.
There are a lot of ideas floating around on the blogosphere, some good and others questionable. Composing a manuscript and submitting it to a reputable scientific journal is a good way to demonstrate that your idea holds water, and it's also a good way to communicate it to the scientific community. The peer review process isn't perfect but it does encourage scientific rigor. I think Metzgar is a good example of someone who has successfully put his ideas through this process. Pedro Bastos, who also spoke at the Ancestral Health Symposium, is another example (3).
