Supermarket extra virgin olive oils
The health benefits of the Mediterranean diet – of which extra virgin olive oil (Evoo) forms a key part – are widely known, but Evoo also delivers a notable flavour boost to your food.
The term Evoo is protected under EU law and guarantees the oil is cold-pressed (no heat is used to extract the oil from the olives) and extracted mechanically, without chemicals. Non extra virgin olive oil may be extracted using both heat and chemicals, and will be less beneficial in terms of nutrition.
