For those of us growing up in the 70s, 80s and 90s we were told that eating a low fat diet was healthy and we switched from high fat butter to margarine, full fat milk to skimmed milk and we stopped drizzling oil and butter on our salads and vegetables. Thankfully those days are now behind us and finally the message that eating low fat is healthy is starting to be replaced by the message that eating healthy fats is good for you. However, I still find there are many people that cling onto eating a low fat diet and have a fear of eating any fat. The idea that eating fat makes us fat was first touted in the 1950s and since this low fat message we have seen a rise in obesity, a rise in dementia-related illnesses and a rise in heart conditions.
