Healthy food prices

Maybe a bit of both. A lot of these foods cost more because they use higher quality ingredients or it's more expensive to grow something without pesticides because more crops can get ruined by pests. Also since the market for healthier foods is much smaller than that for regular foods they can't be sold at the cheaper prices that come from growing huge quantities of foods on huge farms. Though as organic and other healthy foods get more popular, the prices have been coming down somewhat.

When you say healthy foods are you speaking of organic? If so they do take more work than commercially grown food items, they are in most cases more labor intensive also. Part of it is supply and demand. There are fewer growers of organic foods so there fore less available for those who seek it. Tomatoes you see in the store have been gassed so they are that bright red...they are picked and shipped very green. I know this because I used to pick the tomatoes up and deliver them to the warehouse that supplies the stores. Organic tomatoes are either close to ripen or ripened on the vine, and have a shorter 'shelf life' than other tomatoes. I use tomatoes just as an example, as most your fruits and vegetables are picked green to extend 'shelf life' making it more profitable for the store, shipper and warehouse to stock. I hope this has helped you understand.
