What are nuts?

We think of many foods as being nuts, but what are they really? Nuts are seeds, but not all seeds are nuts. Specifically a nut is a dry fruit with usually one, but sometimes two or more seeds. These seeds are contained in a hard wall derived from the ovary and remain unattached to the wall. Seeds can be removed from the fruit, but nuts are compound ovaries which are the seed and fruit combined. Not all nuts are edible, some are just too small, and others can be very bitter. Culinarily we label many seeds as nuts when they are not. Peanuts are actually legumes. Cashews are a "false fruit" that forms off the end of the cashew flower. Many "nuts" such as almonds, pistachios, and coconuts are actually drupes. Drupes are when a fleshy outside layer surrounds a hard walled seed, such as a peach. Pine nuts are coniferous seeds. Macadamias are kernels of seeds. Did you know that macadamia nuts are toxic to dogs?

Nuts are high in protein and fats, but the fats tend to be the type that are actually a healthy part of our diet. Especially those found in almonds and walnuts. Nuts have many other nutritional and dietary benefits; Pine nuts may curb the appetite and Pecans are good for your heart. So don't feel too bad about eating all those nuts during the holidays, just don't go overboard, and enjoy going nuts.
