Susan food does alter gene expression.
Please see Greek diet post with particular emphasis on balancing the omega threes and sixes.
With the messages on polyunsaturates lots of people me included were happily imbibing high levels of omega six veg oil and relatively low levels of omega three, getting IBS type symptoms etc and thinking that their fat balance was a healthy one.
There is no question that food can figure as a risk reduction strategy, but there is little money in diet compared with drugs so it has not had the same level of funding for trials etc as drugs, and will not until Governements look at the upcoming health bill and social implications of increasing rates of western conditions from a preventative rather than treatment perspective, and fund the necessary rigourous trials (eg based on gene expression, measurements of fats in the body etc) on fats for example. The what did you eat are simply not sensitive or accurate enough so large meta trial results are often mixed and inconclusive.
There is also no question that some are simply more prone than others.
If you have already done the omega three six thing - apologies.
