Yes, it is very hard. The best way, of course, is to grow your own and know exactly what you put on them. If not I am pretty sure there are people who are like minded as you. But they grow their own food and sell.
You are part of the process. Can you imagine if 1 by 1 the number of those people come a 100 or 1000 or later more? That is a big change and supermarkets will have to follow the trends of their consumers. Soon the organic stores would start popping out everywhere. Like we actually do see in the world now. People are waking up 1 by 1. Waking up to the fact we have not been eating "food" for who knows how many years.
Following you now so hopefully I will get to see some of your "yummy healthy things". hehe :)
Have an amazing day. :)
