hydroponic vs soil question

Are Hydroponic Vegetables as Nutritious as Those Grown in Soil?

I like to blog about things I don't know and often wondered about. This is one, is there a nutritional difference between produce grown in soil vs the hydroponic method. I found my answer from a New York Times blogger, Sophie Egan.

There are some of the article that was posted in Dec 2016 at NYT blog: 

"The bottom line is it depends on the nutrient solution the vegetables are grown in, but hydroponically grown vegetables can be just as nutritious as those grown in soil." 

"Keep in mind that nutrient content varies for produce in general, regardless of the growing method. The differences relate to the type of fruit or vegetable, the time of year it is harvested, how long after harvesting the crop gets eaten, and how it is handled and stored from farm to fork."
