people just like the food they are used to:
What is wrong with foods like lasagne, being veganised? Why do people have to change their food culture?
People do tend to like what they are familiar with.....but when what they're familiar with results in some negative outcome its best to change.
Most of the ingredients in lasagna are plant-based so its something you could, in principle, veganize....but honestly I've yet to make or have a good vegan lasagna. Its the cheese.....without cheese lasagna just isn't the same and by focusing on such foods you will be always reminding people that vegan food is inferior food.
I've given an argument in my lost few posts as to why people should change their food culture. The vast majority of animal based products do not have alternatives that are on par taste and nutrition wise as a result vegan food that uses them will be inferior in both taste and nutritional value. On the other hand there are many delicious traditional vegetarian/vegan dishes.
The poor nutritional value of the products may result in a failure to thrive which is a major problem both for individuals and the imagine of veg*n diets in the western world. For the average person, sadly, meat,dairy and eggs are some of the most nutritious parts of their diet and replacing them with heavily processed foods results in a major reduction in the nutritional value of their diet.
anyway, you are probably right that people(me included) should eat more whole foods more vegetables, less fat, and we'd all live more productive healthy lives, but I don't see a complete cultural change..Like me, I think people can include a bit more whole foods, but you can take the vegan macaroni cheese from my cold, dead, hands...
...and probably will...
My point is that a vegan food culture that focuses around heavily processed ingredients is incongruent with current health messages and as a result its going to be a tough sale. Another factor is that the meat, dairy, etc industry will exploit the highly processed nature of these products in their marketing.
And, just to be clear, what I'm talking about here is how to get western society to move towards a more plant oriented diet. The current veg*n community has done a very poor job at this and I think, in part, it has to do with the food culture in the veg*n community. When vegetarians/vegans aren't creating mock dishes.....there are often promoting strange dietary practices (raw diets, etc). There aren't many people out there promoting wholesome, delicious and healthy vegetarian food.
While I don't think eating vegan mac-cheese here and there is a big deal, I don't think its the sort of food that should be promoted.
