Food shopping optimizing it all but still enjoying it

Food shopping optimizing it all but still enjoying it


From time to time everyone of us has to reconsider our food shopping strategies. You either move to a new area, have a new baby, or send old baby away for college, get laid off from work, start a new demanding job, or simply discover new stores in the neighborhood. Either way your old shopping strategy falls apart and you have to piece it back again ensuring everything is covered, feasible and optimal.


You want to remember it all - baby products, kids breakfast foods, fruits and vegetables, meats, breads, dinner components, cleaning supplies - and renew it all on a weekly basis. What is your strategy for accomplishing this?

For a few years I have been encouraging you to create and utilize a Master Shopping List and even posted  my list for you to copy and edit. I advised to check the supplies before leaving for the store, crossing everything you dont need to get, take a pencil with you to the store and check-mark the items as you drop them into a cart.  But guess what, I am seriously questioning this strategy now.

It may be the new baby that we got that requires a load extra items; or the frequent long lines in the meat department, but I came to realize that my weekly shopping became an impossibly tedious and dull process that I am always trying to postpone. It takes me about an hour to zigzag the supermarket and efficiently gather all the items on my list. But approximately after 30 min it stops being fun. The pleasures of smelling fresh produce, trying samples, browsing through and discovering new products or combinations, planning the meal in my head - all expire at about 30 min from the store entry and all my senses shut down. I feel like a pawn in a reality show trying to mark off all the remaining items in a least possible time. At about 60 min threshold I get angry and start transferring my anger to the foods in my basket. A very sad beginning of the food as a pleasure process.

 I discover that I enjoy short specialized shopping trips much more than I enjoy one long exhaustive food purchase.  Biweekly stops at a bakery, weekly order from a fruit and vegetables farm, one or two quick specific visits to the supermarket (breakfast stuff only, dinner products, diary and meat items).  I still do shopping lists but not the long master shopping list that I believe turns me into a food soldier.  I create short lists of absolutely-do-not-forget products and try keeping the number of items in them below 20. This way I can keep my eyes on the shelves rather than in the list and let me mind explore and discover, noting, touching and smelling the items. I feel that I am adding fun as a new component to my overall shopping puzzle that already included time and money optimization, overall product coverage and product quality.  The new strategy is definitely more time consuming but the fun factor makes it much less strenuous.

I think long shopping lists are still great for some people (aka food soldiers)  and some situations. If, like my father, all you want is to restock on the items your wife asked without adding any frivolities, you cannot accomplish it without a long list.  If you have to assemble an elaborate meal consisting of tens of obscure ingredients, you need the list and the focus on the list. You cannot avoid the long list also when coming back from a vacation.  But for the rest of the days I insist on making my food shopping an adventure. What about you?

Fracking Does Contaminate Groundwater With Methane But Jury Still Out On Process Overall

Fracking Does Contaminate Groundwater With Methane But Jury Still Out On Process Overall


A study has been undertaken by Duke University of methane levels in water from 68 private wells above the Marcellus and Utica shales in Pennsylvania and New York. The details have just been published in the Proceedings of the National Academy of Sciences http://www.pnas.org/content/early/2011/05/02/1100682108.full.pdf+html. Of these, around one third were in an "active extraction area", which by definition is within one kilometre of a gas well, the remainder being more distant.

The results of the study are striking: in all but one case, making 15 altogether, it is only within 800 metres of a gas-well that levels of methane are high enough (10 - 28 mg/L) to merit warning of the occupants and prudent remediation down to levels ; 10 mg/L, according to the US Office of the Interior, or above 28 mg/L at which point "potentially explosive or flammable quantities of the gas are being liberated in the well and/or may be liberated in confined areas of the home," which requires immediate mitigation. http://arblast.osmre.gov/downloads/Mine%20Gases%20and%20Dust/FINAL-Methane.pdf

In this particular study, no evidence for fracking fluid finding its way into the groundwater was found nor for intrusion from deep saline brines into aquifers closer to the surface. According to an isotopic analysis, the excess methane is consistent as originating from deeper thermogenic sediments, rather than being produced biologically in near surface environments.

The Energy Institute at the University of Texas is set to conduct the first integrated study of the science, policy and environmental issues surrounding hydraulic fracturing to recover shale gas at a cost of $300,000, with preliminary findings expected to be released in October. This project aims to combine an independent assessment of groundwater contamination, fugitive air emissions and seismic events for which fracking has been blamed in shale formations, and to evaluate the effectiveness of legal regulations attendant to the process, focussing on Barnett Shale, which extends under over 20 counties in North Texas . The Environmental Protection Agency is conducting its own investigation with results expected after the end of the year 2012.

The overall conclusions of these studies could not be more crucial to future US energy provision. Production of shale-gas was 2.02 trillion cubic feet (Tcf) in 2008: a 71% increase over the previous year, which in 2009 grew 54% to 3.11 Tcf. Proven US shale reserves at the end of 2009 were observed to increase by 76% to 60.6 Tcf. In its Annual Energy Outlook for 2011, the US Energy Information Administration (EIA) more than doubled its estimate of technically recoverable shale-gas reserves to 827 Tcf from 353 Tcf, by including exploration data taken from new fields such as the Marcellus, Haynesville and Eagle Ford shales. It is estimated that shale-gas production will increase from 14% of total US natural gas production in 2009 to 45% by 2035. But this of course depends on whether the process of hydraulic fracking is proved sufficiently safe to be so widely adopted.
