Today I had to make a trip to the health food store and paid double the regular price of the regular version in tesco.
When in France last week I had a very different experience - I needed soy sauce for my marinated salmon. At the local spa supermarket, not a big store by any means, I bought their own brand soy sauce for half the price of today's purchase, ingredients: soy, water, salt.
I think this nicely summarizes a key problem in british food culture - we are quite happy to buy any old rubbish. If we all shopped critically and only bought food that only contained the proper ingredients then I wouldn't have to go schlepping around looking for soya sauce with only soya in it!
So this weeks shopping challenge is to only buy food with three or less ingredients, if the food you want requires more than three then make it from scratch yourself. This way you're much more likely to use fresh ingredients and get a more nutrient rich diet, without lots of added nonsense. And maybe after a while the supermarkets will start stocking food without the added nonsense!
