Planck's concept of "real food" is grounded in her mother's lessons on the farm in rural Virginia where she grew up: food should be whole, nutritional, simple and unprocessed–and it shouldn't require lots of ingredients. Essentially, we should eat the kinds of foods our ancestors did, she says, instead of settling for less-healthy, industrially engineered "ersatz food."
Planck is a big proponent of dairy and, in particular, unpasteurized, unhomogenized milk, which she says is safe as long as you know (and trust the hygiene standards of) the farmer you get it from. In fact, she thinks that raw milk is like a "gateway drug" to better eating, generally. And while industrial meat production is often blamed for environmental damage, Planck says that eating grass-fed meat can actually help the environment.
