When shopping...

By now I am familiar with most the products I buy on a regular basis. However I double check the items generally on the ingredient list really quickly. The items to watch out for become such second nature, that I can mostly spot them on the first glance. If however I see that an item (even if it is unfamiliar brand) is parve I never double check. It is kosher and to be pareve

"...Foods that contain no dairy or meat content are known as parev (also spelled pareve). Examples may be most drinks, all fruit, and raw vegetables.
Pareve food and drink can be consumed with either dairy or meat meals..."
