NEW YORK ( TheStreet) - In yesterday's edition of the Resource Prospector , I discussed a few things I'm doing to protect myself from the increasing likelihood of food shortages and general fallout from the effects of currency depreciation and energy cost increases.

And I received some excellent additional advice from some readers.

Laura wrote in to say: "Hi Kevin, Good to see someone from the investing world talking about the real dangers to middle America. Mainstream media will never touch on this topic for fear of creating panic. So by the time we have double digit food inflation it will be too late for many families who live on the edge to prepare.

The main thing to tell people is not just to buy metals on the dips, but to buy food on the dips too. Here's what I mean. Yesterday I went for regular grocery shopping. The store was having buy 10 for $10 deals on many of the items I regularly purchase. So I took advantage of that, and placed half in storage. When buying food for storage, buy what you normally eat, as long as it can be stored a long time.

Then in addition to that, buy things that are trade-able -- I mean extra cans of coffee, tea, cocoa, chocolate bars, laundry detergent, etc. When you see a breakdown in restocking store shelves because retailers can't figure out how to stay ahead of inflation, you'll be glad to have a little extra set aside, and to have something to trade for items you are missing.

But the biggest piece of advice in metals is to purchase a bag of small denomination silver -- like a bag of dimes. You can't go wrong here."

That's excellent advice Laura. Thanks for the input.

Matthew wrote in to tell me about another commodity that most people don't think of: "Take a closer look at "water. There will be, sometime in the next couple of years, problems with our domestic and global water supply, be it natural catastrophe (drought), terrorism or man-made blunders that threaten our drinking water supply. This will cause rises in the stocks of companies that produce and supply us with drinking water. Just another suggestion in relation to your Food Riot article. I believe that the importance of water will eclipse that of oil in the 21st Century.
