Think about how we now see food - ie low fat. low salt, low sugar etc how we now try and promote healthy options.
Consider what makes people change - a better understanding of what 'goes into' some foods - like all the narsties that may/may not be in some fastfoods, which could increase the use of organic foods
How animals are treated - this may effect what is eaten.
Also how media may effect eating habits - when someone published research saying fish oils are good for the brain - more people started eating oily fish. Isn't there an advert with 'fishy milk'? .....Well milk with added fish oils or something!!!!!
