4. Cold pressed oils have a strong flavour  

Cold pressed oils retain some part of the nutty flavour of the seed and typical natural aroma, which may exhibit a strong taste initially.  The way to counter this is to use less oil,  and in fact it enhances the flavour of the dish while reducing oil consumption. 

 5. Cold pressed oils may retain allergens

Many people may be allergic to nuts (especially peanuts). The allergens in the peanut will most likely pass on to the oil, since it is minimally processed and retains all the qualities of the oil seed. It is better to try a small patch test before diving fully into cold pressed oils.
