I only buy Fuji apples and was so glad that my grocery store started carrying organic Fuji's, they are so much better than non-organic.
I try to buy all organic fruits and veggies. Bananas to me taste better organic. I haven't noticed a difference with carrots but I always eat them steamed or grilled. Organic spinach and baby lettuce tastes better and mushrooms too. I'd like to try fresh organic green beans, I read they have like 50+ chemicals and pesticides in them so I'm anxious to see if they taste better.
I buy organic raisins, since organic grapes taste so much better, for the kids, I don't eat them though.
We went to one of our locals farms in June and bought strawberries. They were not organic but were the best tasting strawberry I have ever had in my life. They were acutally strawberry red in color, smelled wonderful and tasted like a strawberry should taste. Not something picked in California and shipped to Pennsylvania! I will not waste my money on strawberries again, unless they are in season here.
The only juice I buy now is organic apple juice and it tastes so much better than any other juice I've ever had, tastes like fresh apple cider.
I don't drink milk but I have been buying organic for 3 1/2mo now my dh says it tastes better, the boys don't really notice.
Organic jelly is much better than the jelly with high fructose corn syrup. I too was surprised at how good it tasted. I buy the concord grape Cascadian Farms brand and it smells and tastes just like a grape. I don't mind having a pb&jelly every once in awhile! I really want to try a good organic peanut butter.
Coleman Natural bacon and premade frozen burgers taste better to me. I always buy antibiotic/hormone free chicken (although not stated as organic) but don't notice it tastes better. I just feel better about consuming it.
Egglands eggs or any other antibiotic/hormone free vegetarian fed brands. They taste better and are much bigger.
I don't know about tasting better but I buy organic cereals for the kids.
I haven't bought any yet buy I want to make the switch to organic coffee.
