Food Guide



There are about ten species of peanuts, each with several different varieties. However, three varieties are widely produced for consumption: the small, round Spanish peanuts; the medium-sized oval Valencia peanuts, often sold in the shell; and the large Virginia peanuts, which are often found in cans and jars of mixed nuts. All three varieties can be used interchangeably.

Preparation, Uses, & Tips

Peanuts can be eaten whole as a snack or used is a wide variety of dishes, both sweet and savory. They are very popular when ground into peanut butter. The peanut is a staple ingredient in many cuisines of the world, including African, Indonesian, Indian, and South American.


Both shelled and unshelled peanuts should be kept refrigerated in tightly sealed containers. Unshelled peanuts will keep for up to nine months in the refrigerator, while shelled peanuts will keep for up to three months. It is important to discard peanuts that are discolored or even slightly moldy or rancid since they can be easily contaminated by aflatoxin, a mold that has been linked to cancer in laboratory animals, though not in humans.
