Peanut facts

Widely regarded as nuts, peanuts are actually legumes (like beans, peas and lentils) and grow under the ground, not up in trees. The peanut plant is a low bush whose stems burrow beneath the soil where the pods containing the peanuts mature (a little like potatoes). We often say, peanuts “the nut that’s really a bean”. Their nutritional profile is similar to olive oil, with heart-health monounsaturated fats and they also contain protein, fibre, vitamins and minerals.
