The last couple of days I’ve felt kind of crummy. The kind of crummy that often precedes a change in the weather.

If you’re in Ottawa, then you know that we’ve had unsettled weather since Wednesday morning, which corresponds to when I started feeling crummy.

This isn’t the first time that I’ve commented on this phenomenon. The last time was in October 2008 when a big low-pressure zone blasted through Ottawa.

The graph shows the pressure in Ottawa for the last day or so. And during this times I’ve felt varying degrees of crummy.

When the weather was clear sky and warm earlier this week, I was feeling great (and not just because of the sunshine).

Do you feel the weather?

“Mmmm … bacon.”

Though apparently never actually uttered by Homer Simpson according to The Simpsons Archive (he did say “mmmm … unexplained bacon” in one of the Hallowe’en episodes) I know many people who feel this way when it comes to bacon.

According to a story in Sunday’s National Post, bacon and cheesecake have the same effect on your brain as heroin and cocaine. When rats that were raised on regular, healthy rat food were given unfettered access to high-fat foods, they became so addicted that even mild foot shocks weren’t enough to convince them to stop eating to excess. The changes in the rats’ brain chemistry noticed by the researchers were the same ones noticed in cases of additions to heroin and cocaine.

To break the addiction, they had to use a special virus that sort of “reset” their dopamine receptors so they would start eating healthy food again because after two weeks of being forced to go “cold turkey” (so to speak) the rats had not returned to their healthy diet. It seems they would rather stave than eat healthy.

This explains much.

I was getting caught up with a friend recently and he mentioned that he and his wife had had a bit of a scare a few days ago when their carbon monoxide detector went off. They quickly got out of the house and called the fire department who confirmed that there were elevated levels of CO in the house, particularly in the basement near their natural gas furnace and water heater.

Fortunately, no one was hurt.

A furnace guy spent three hours checking out their furnace and water heater, but he couldn’t find any problems, so the source of the carbon monoxide hasn’t been positively identified, which is a bit troubling. But they do have the carbon monoxide detector upstairs and I think they’re going to get another one for the basement.

Carbon monoxide is a colourless, odourless, tasteless gas that is highly toxic. It is formed during the partial combustion of compounds that contain carbon, particularly in internal-combustion engines. Basically, it bonds with red blood cells much more readily than oxygen molecules do, which brings on a whole host of unpleasant effects up to, and including, death. If you are poisoned, chances are that you won’t realize it since one of the effects is to make you dizzy and confused.

Purging it from your system isn’t simply a matter of getting into fresh air. Because it bonds so well to red blood cells, it takes a long time to work its way out, though breathing pure oxygen can help accelerate the process. There can be long-term effects such as memory loss, confusion or even permanent brain damage.

Sadly, six people from two different families in Ontario have died in the last month due to CO poisoning and it kills 300 people in North America every year.

Bad stuff.

Over the last couple of years, I’ve noticed that I start feeling crummy between 18 and 24 hours before a significant weather change. I haven’t kept any records to see if it’s predictable, but I suspect it is.

Well, yesterday evening around 10pm or so, I started feeling crummy, which persisted through to sometime this afternoon. Even now, I’m still feeling a little blah. I happened to see the nurse at work this afternoon and we chatted about this for a bit. She told me that I’m not the first person to mention something like this to her and described, almost perfectly my symptoms, namely feeling kind of "fuzzy" like you have a headache about to form.

So, I looked up the air pressure readings for Ottawa for the last twenty-four hours. I started feeling under the weather (sorry!) around the same time the pressure started dropping. If you click on the graph at the right, you’ll be able to see a larger version.

The graphical area forecast (GFA) for the Ontario-Quebec region for 8pm this evening (click on the image to the left) shows Ottawa sitting on the 996 millibar isobar, so it doesn’t look like the pressure is going to drop much more than it has.  (At 5pm it was 99.9 kPa or 999 millibars.)

Oh, and I just looked out the window to see the first snowflakes of the season.  Sigh.

I’ve been reading a travel-related blog called Gadling lately.  Recently, one of the bloggers there recounted his experiences on a Southwest Airlines flight and ranted about the fact that he wasn’t served peanuts on the flight.  Apparently, Southwest Airlines opted to not serve peanuts because one of the other passengers was very allergic to peanuts.  The blogger was very skeptical that there are people with allergies that are so severe that they can’t even be in the vicinity of the allergen.

Unfortunately, there are.  And there’s an increasing number of people with nut allergies.

Three days ago I made a comment in my entry about Campbell’s soup that the government would probably adopt legislation concerning sodium levels in Canadian food within the next year.  Well, this morning’s Ottawa Citizen has a front-page article titled Health Canada wages war on excessive salt intake.  It reports that there is now a federally appointed working group that is tasked with developing a plan to reduce sodium levels in food.  It’s expected that they’ll recommend Canada adopt the British strategy, which has seen the average daily intake of sodium by adults in Britain drop by 500mg between 2001 and 2006.  The impact on pre-packed meals has been a 45% reduction in four years and 85% have already reached the targets set for 2010, which is a more than one third reduction.

It’s about time.

Data from the Canadian Stroke Network indicates that nearly 11 000 Canadians a year die because of the effects of excessive sodium intake.  It has been linked to hypertension (high blood pressure), stroke, cardiovascular diseases and asthma, to name a few things.

So, hopefully this sounds the end of the roast beef sandwich with 2 grams of sodium in it.

Campbell soups for kids and some of their other soups are becoming healthier (story that tipped me off). The amount of sodium per serving is being lowered to 480 mg.

Sodium is found in most things you eat and particularly in processed foods. Some products, such as bagels from the Ottawa Bagel Shop have a mere 5 mg of sodium per bagel. I was talking with someone at the shop about this a couple of days ago and he confirmed that the only sodium in their bagels is that which occurs natually in the ingredients. Other bagels, particularly the mass-produced ones, are often made from dough similar to bread dough, and have a much higher sodium content.

Statistics Canada published results of the 2004 Canadian Community Health Survey (CCHS) last April that revealed that most Canadian consume much more sodium than is necessary or recommended. The Statistics Canada report quotes the Institute of Medicine recommended daily adequate intakes for sodium as being 1500 mg for someone aged 9 to 50. I blogged about the 2000 mg of sodium that was in a sandwich I bought on an Air Canada flight in December and how unhealthy that was.

My guess is that we’re going to see legislation on sodium levels in food similar to those in Europe introduced sometime in the next year or so.

Kudos to Campbell’s for taking the initiative and doing this voluntarily. Hopefully other food companies will follow their lead and work at making their products a little healthier.
