No, fresh food is not as nutrituous as it once was. Food and vitamin standards were last seriously evaluated in the 1960s. Since then hydroponics and global agrinomy have evolved. If I grow you lettuce in a tank of tap water will it have the same vitamins and minerals as if I grow it in the soil? NO. it will NOT. Simple answer to your question. However, a 7.38$ organic cucumber is probably not worth it nutritionally versus a $0.48 non organic one. Standards are in dire need of revamping for the post 2K 2000 era to make intelligent decisions.
