Obst und Gemüse verlieren immer mehr an Nährstoffen

Frischkost enthält weniger Vitalstoffe als noch vor 50 Jahren.
Fünf Portionen an Obst und Gemüse pro Tag sollen, laut Empfehlungen der “Ernährungsexperten”, den Bedarf an Vitaminen und Mineralstoffen decken. Das ist falsch!
Einige frühere Studien haben dies schon widerlegt und eine aktuelle amerikanische Studie bestätigt es wieder:
Obst und Gemüse sind längst nicht mehr so vitaminreich wie früher.
Laut der aktuellen Untersuchung fällt der Gehalt an Vitalstoffen seit den 70er-Jahren rapide ab: Der Verlust von Vitamin A bei Äpfeln beträgt 41 Prozent. Paprika hat um 31 Prozent weniger Vitamin C und Brokkoli nur noch die Hälfte an Eisen.
Blumenkohl hat heute nur halb so viel Vitamin C, B1 und B2 als noch vor 40 Jahren. Ausgelaugte und schadstoffbelastete Böden in der Landwirtschaft führen zu einem drastischen Verlust an Mineralstoffen und Vitaminen in der Nahrung. „Der Mangel an Magnesium in der heutigen Ernährung ist auffallend“, bestätigt Arzt und Biochemiker Jörg Birkmayer.
Und US-Mediziner Al Sears meint: „Sie müssen heute zehnmal so viel Obst und Gemüse essen, um die gleiche Menge an Vitaminen und Mineralstoffen wie vor 50 Jahren zu bekommen.“ Wem das zu viel erscheint, muss zu diversen Nahrungsergänzungsmitteln und Vitaminsäften greifen.
Kommentar: Neben unreif geernteten Früchten, UV-Bestrahlung, langen Transportwegen und Lagerzeiten, werden die Landwirte durch das kapitalistische System dazu gezwungen auf Quantität, anstatt auf Qualität zu setzen. Die Böden können sich nicht erholen, werden ärmer, verlieren ihre Nährstoffe und werden zusätzlich mit Chemikalien (Düngemittel und Pestiziden) verseucht.
Genetisch verändertes Saatgut (vor allem in den USA – zunehmend auch bei uns) kommt Dank der politischen Lobbyarbeit der Agrarkonzerne vermehrt zum Einsatz. Das ist eine Tragödie die auf kurzfristiges Denken und Geldgier beruht. Was werden die Menschen essen, wenn die Nahrung nichts mehr wert ist? Müll natürlich… Und was passiert dann? Eine zunehmend kranke Gesellschaft.
Wer zu Nahrungsergänzungsmitteln greift sollte jedoch auch hier auf erhebliche qualitative Unterschiede achten. Grundsatz: alles was künstlich ist, macht den Körper längerfristig krank!

The 10 coolest urban gardens in the world

1. Prinzessinnengarten (Berlin)

Prinzessinnengarten is a green and social project in the heart of Berlin, in the Kreuzberg district. Since 2009 an urban wasteland has been reclaimed with the help of hundreds of volunteers, creating a vibrant space for growing herbs and vegetables, always open for the community.

2. Graze the Roof (San Francisco)

Graze the Roof is a community garden installed on the roof on the progressive Glide Memorial Church in the Bay Area. Built with upcycled materials and equipped with a worm composting system, it hosts workshops for the community and other social activities whilst growing vegetables and keeping bees.



3. Brooklyn Grange Farm (NYC)

One of the most fascinating (and media favourite) urban agriculture projects of recent years,Brooklyn Grange Farm grows organic produce that sells in New York City markets, as well as to local restaurants and retailers. They even run a CSA program (fully booked!) and the lush space can be booked for events. Watch this mesmerizing video showing a growing season in 3 minutes:

4. Lufa Farms (Montreal)

Another commercial rooftop gardening enterprise, this one in greenhouses. Lufa Farms grow more than 40 types of vegetables with a hydroponic system, recirculating 100% of the irrigation water and with no synthetic pesticides. If you live in Montreal area, you can even buy their produceonline.

5. Agropolis Urban Farm (Christchurch, NZ)

Agropolis Urban Farm is part of a wider movement to bring a more sustainable food system to Christchurch, New Zealand.  One of the most important tasks in the hands of this emerging collaborative project is to compost and recycle the waste coming from bars and restaurants in the city.

6. Pop Up Patch (Melbourne)

Staying in the southern hemisphere, Pop Up Patch in Melbourne is a subscription based gardening club where every member rents and tends a vegetable patch to grow his/her own food (groups and families are welcomed too). There are still some spots available, so if you live in the area, “for the price of a coffee a day”, you get your own little garden and all the help and encouragement of the Pop Up Patch team.

7. Soradofarm (Tokio)

This one is for transient gardeners. Soradofarm if a program that keeps gardens of train station rooftops so that waiting passengers can do a spot of gardening while the next train comes.

8. Murs à pêches (Paris)

Did you know that Paris used to be a hub of the peach industry? Starting in the seventeenth century, a maze of walls and plots formed a mediterranean-like microclimate in the Montreuil neighbourhood that produced tons of fruit for the Parisian aristocracy. Now the Murs à Pêchesassociation (translated as “Walls of Peaches”) is working to revive the abandoned orchards to restore them as a urban garden and a cultural space.

9. Growing Underground (London)

Anyone who has taken the tube in London knows that in can be hot down there.  Now two entrepreneurs have launched an initiative called Growing Underground to make use of some of that heat to grow salad greens in spaces once used as WWII shelters in the London underground system.

10. Urban Farm (Dublin)

Ireland’s first urban rooftop garden Urban Farm is located in the Dublin city center and aims to “convert urban spaces into tangible edible benefits for the community”.

We are well aware that this list is not comprehensive, urban gardening projects are mushrooming everywhere. Do you know any other cool urban gardens we should know about? Go on, tell us and spread the good news!!

Aeroponic

The world's 4th busiest airport brings a new meaning to sustainable agriculture. O'Hare International Airport in Chicago uses Aeroponic Towers to grow enough veggies to feed over 10,000 hungry travelers a year. Local, GMO free, chemical free - add renewable energy to the mix and it couldn't get much better. We think every airport and shopping mall should have a similar garden. What do you think?
