Diamond Foods (DMND) acquired the Pringle brand product from Proctor & Gamble (PG) for $2.35 billion, as reported in Dealbook.

When we think of Diamond Foods we think of nuts, edible nuts. Diamond's two main brands are Diamond and Emerald. It produces all kinds of nut products for cooking and eating. Among them are almonds, Brazil nuts, hazelnuts, pecans, pine nuts and peanuts. The product line also includes microwave popcorn and potato chips.

Behold the humble potato chip, snack food of the ages. Claimed to have been invented in 1853 in the road house kitchen of Native American George Crum, the potato chip traveled through American snack history in a class of it's own. That is, until in the early 1960s, when it was discovered that you could grind potatoes into a slurry and then press them back into a consumable form.

I sat down one day with a bag of potato chips from Lay's and with a can of Pringles. Lay's are made by Frito-Lay, a property of PepsiCo Inc. ( NYSE: PEP). Pringles are made by Procter & Gamble Co. (NYSE: PG). I wanted to compare the two in order to assess their similarities and differences. What I found were two very different snacking sensations although both are derived from the same source. The Lay's ingredient list is simple. They're made with potatoes, oil, and salt, with no preservatives added. The Pringles ingredient list begins with the same potatoes, oil, and salt, but the product also contains at least traces of wheat starch and rice flour in addition to a couple common food chemicals.
