Diet Specific

Earlier this week I briefly considered becoming vegan, without going in to all that, I looked around the internet to see what food options I’d have left. I was quite surprised how little information there was in terms of buying food from major supermarkets.
My idea is for a website that pulls in information from the online supermarkets to create tailored shopping baskets for specific diets. So if you were allergic to gluten, for instance, you could easily create your order without having to go through all of the ingredients each time you’re considering a product.
My Supermarket is a supermarket price comparison website that pulls in and compares products from all the major supermarkets to find you the best price. This could work in a similar way so you could see which supermarket can offer you the best choice, and allow you to fill your shopping basket on the site itself.
All major online supermarkets have a list of ingredients and allergy advice with each product, thereby it should make it possible to eliminate certain unsuitable products.
Potentially products could also be sorted according to place of origin, for those concerned about food miles. Obviously this may be a little more difficult as this would vary with seasonal groceries, but I think it would be a very useful tool, and may mean people are willing to spend a little more for environmental reasons.
