Hydroponics vs. health

[sylvestris]

Hi!

I've recently got myself into a debate on a swedish gardening forum (I'm from sweden) about wether or not hydroponics are good or bad for your health.

I've read that hydro veggies actually contain more vitamins that soil grown veggies if grown correctly. However some soil-fanatics claim that hydro veggies lack certain nutrients and vitamins that the human body needs.

So I'm turning to you guys, help me with arguments to win the forum battle against the soil fanatics!

.... on a more serious aspect. Please tell me what you know about the health effects of hydro grown veggies. It would be nice to know since I'm eating the veggies I produce and It's nice to know what I'm eating and serving my family
