Items to get in the grocery shop: bread, milk, eggs, soil… soil? Yep. Some pregnant women out there can’t seem to stop salivating over soil. Whatever it is that causes this craving, you’re not alone if you experience this too. Britney Spears revealed that during her pregnancy with her second son, she couldn’t stop thinking about a generous serving of soil alongside her fried chicken cravings. This strange desire turns out to be quite common; in a 2008 survey of pregnant women, mud made it into the list of top 10 pregnancy cravings. Although there is no scientific evidence to suggest why this craving can occur, scientists suggest that the desire for soil during pregnancy could be the subconscious need for pre-natal vitamins such as copper and iron, which soil is brimming with. Ingesting dirt is also believed to ease morning sickness, although with all those bugs and parasites we certainly wouldn’t recommend it.
