| Oils high in naphthene also contain more impurities such as phytotoxic aromatic and unsaturated hydrocarbons. |

| The fat is mainly unsaturated, so potentially healthful, although all fats are equally high in calories. |
| And you can have some unsaturated fats like salad dressing, cooking oil, nuts, and avocado. |
| In common with all unsaturated hydrocarbons hydrogen can be added across the double bond to produce ethane. |
| These unsaturated hydrocarbons are readily oxidised and polymerised, which can reduce the oil's shelf life. |
