Since no-body else is touching this…I will try. However, I am NOT and expert and you should just take what I write as a small part of your research…and if it disagrees with other research - discard it 
I also do not feel comfortable with U.S. dollars…however be VERY careful. I tend to be contrarian…and that philosophy has been good to me so far. If everyone is concerned about the U.S. dollar and wanting to dump it then it probably is a good idea to not do this (contrarian). The reason being is that a large number of people have already done so and, in addition, when the news turns more positive, demand will go up for the dollar. The dollar is possibly at its low right now and may actually get stronger…so acting to dump dollars may hurt you at this time.
Remember…the dollar has gone up 40% in the ‘stock market’…in that the stock market has decreased 40%…
So owning dollars short term can be GOOD GOOD! 
What you want is to not own dollars over the long haul. This looks simple…but the problem is that your salary is in dollars
and the vast majority of the other people around you deal with dollars. So, when they hurt, you will hurt even if you don’t have much dollars.
Land/house, for example…not dollars. However, if other people are hurting, your land/house will get less in dollars. However, in theory, your land/house is worth what it is worth and if dollars inflate hugely…it’s theoretical valus is the same. Stocks as well. A company is worth what it is worth…and the currency is irrelevant. If the dollar deflates, the stock should be worth ‘the same’ as it was before.
However, in practice the value can go down as demand goes down because people are hurting.
So, you need something disconnected from the U.S. dollar AND your fellow citizens. Well…you could just pick up some foreign currency. 2 big problems with that:
-
Owning currency is bad. Currency is DESIGNED to decrease in value over time. You don’t want to own something designed to lose value.
-
The cost of trading dollars for Euros and back again is too high.
You could own foreign stock. The stock market is great in that it allows you to pick up foreign companies without going to that countries stock exchange. Many foreign companies trade on the U.S. stock exchanges. Over the past few years I’ve own stock in a South Korean telecommunication company (that one was good "), a Polish vodka distribution company…a Brazilian mining company and many others. However, the global market is getting more in synch and when bad times hit…they all seem to be affected.
You could own gold or other precious metals. However, be leary of this because people tend to buy or sell these at the wrong time (contrarian again).
So, what do you do? Well, what I have done and am doing now is studying the markets…getting out when technical analysis tells me to and going back in when things look like I should. It has done me well but it takes work.
If you do not want to do all the work…then possibly look at global mutual funds and domestic ones as well. Yes, you will have sickening downs and exhilirating ups…but is probably the safest one can be against inflation.
