Seed Oils in Salad dressings

The fresh salads that are available from Woolworths are very nice BUT the dressings they put with them all contain seed oils, (eg Canola) as do their bottled salad dressings. They try to hide the fact that they contain seed oils by showing the good ingredients in bold print and the seed oils in the fine print hidden in the long list of ingredients. Seeds oils like Canola oils are unhealthy and cause inflammation and I for one would like to see them excluded from salad dressings.
