Nuts 101

There are two basic varieties of nuts: "ground nuts" and "tree nuts". As you might expect, groundnuts grow in the ground. Peanuts are an example of a groundnut. Almonds, filberts, cashews, walnuts, pecans, and pistachios are tree nut varieties that grow on trees.

Nut Nutrition

More and more people are discovering the great news about nuts. Clinical studies have shown that nuts can lower levels of LDL cholesterol, or "bad" cholesterol, when substituted for food high in saturated fat and eaten as part of a low fat, low cholesterol diet.

Much of the fat in nuts is monounsaturated and polyunsaturated, the same kind of fat found in olive oil and canola oil. Monounsaturated and polyunsaturated fats, sometimes called "good" fats, help the body lower cholesterol when they replace saturated fat in the diet.

Nuts about Nuts: Varieties


Originating in China, almonds contain fibre, and copper. Almonds grow on trees, which is why they are also categorized as "tree nuts".

Nuts have a high oil content that makes them susceptible to spoilage. To keep shelled nuts from turning rancid, store them in the refrigerator. If you buy nuts in bulk and want to keep them for several months, store them in the freezer.

Shelled nuts can be refrigerated up to 4 months and frozen up to 6 months.
