The Centers for Disease Control and Prevention calls it "one of 10 great public health achievements of the 20th century".<br /><br />Still, we have plenty of tooth decay. I am reading Humboldt's "Personal narrative of a journey to the equinoctial regions of the new continent". On page 121 he says that:<br /><br />"It could be said that Indians do not know toothache, and Spaniards who live in the Tropics do not suffer from this pain either."<br /><br />Humboldt is generally reliable. These folks ate plenty of carbs, in the form fruits and starches. Fruits have sugar. And I don't think fluoridation of water was a priority for them.<br /><br />I like the wobbling bicycle analogy Aaron!Ned Kockhttps://www.blogger.com/profile/02755560885749335053noreply@blogger.comtag:blogger.com,1999:blog-8859456735165996893.post-26875924496402464802010-08-05T21:31:44.673-07:002010-08-05T21:31:44.673-07:00"We smart humans can't help messing thing..."We smart humans can't help messing things up, eh?" That's an astute comment. I've been thinking for a few months now that politicians, policy makers, and administrators of any kind and persuasion really need their version of a Hippocratic oath "do no harm". If one is not sure whether an act--though meant for good--may have unintended and unexpected negative consequences, then don't act! Do no harm. I feel like society is a wobbling bicycle going at top speed. Every action a politician or law maker takes to try to correct the bicycles course only sends it wobbling off in the opposite direction. We need to stop the bike, take a deep breath, and get back on at a slow and steady pace.<br /><br />Take the "statins in the public water supply" example. Who knows what the unintended consequences may be? Look at what fluoridation of our water supplies may have done (so we can keep munching our sweets, presumably). Public policies should not be allowed to go forward when we are blind to the consequences (which is just about always). Okay, enough of my libertarian rant.Aaron Blaisdellhttps://www.blogger.com/profile/17204484453346358921noreply@blogger.comtag:blogger.com,1999:blog-8859456735165996893.post-81188970738734435812010-08-05T15:24:05.650-07:002010-08-05T15:24:05.650-07:00Hi Berny3.

The reason is that when professional landscapers are hired to plant trees in industrial parks, median strips and other public places, they try to avoid planting female trees, which are considered "messy" because they drop seeds and/or fruit. So, assuming a tree can be identified as male or female, males are chosen, which of course contain pollen.Berny3https://www.blogger.com/profile/00122216306710696007noreply@blogger.comtag:blogger.com,1999:blog-8859456735165996893.post-38770540816205439172010-08-05T08:50:20.719-07:002010-08-05T08:50:20.719-07:00So what you are saying is that obesity is caused b...So what you are saying is that obesity is caused by global warming?Ambernoreply@blogger.comtag:blogger.com,1999:blog-8859456735165996893.post-75341531891976061892010-08-05T07:42:48.105-07:002010-08-05T07:42:48.105-07:00Hi Gretchen.

One interesting thing about your experience is that the allergies disappeared after the T2D diagnosis.<br /><br />Both cortisone and cortisol suppress the immune system. This may sound odd, but the stress caused by the diagnosis could have led to a period of chronically and highly elevated cortisol levels.<br /><br />Those high levels have a number of negative health effects, but they will suppress the immune system and thus should alleviate allergy symptoms.<br /><br />Cortisone has long been know to suppress allergies (more in some people than in others), but it also has many negative side effects.Ned Kockhttps://www.blogger.com/profile/02755560885749335053noreply@blogger.comtag:blogger.com,1999:blog-8859456735165996893.post-85796919378586130432010-08-05T06:42:33.795-07:002010-08-05T06:42:33.795-07:00I've had hay fever since I was a child.

I remember walking home from school with my eyes running and itching.<br /><br />In college I was tested and found to be allergic to tree pollen and mold.<br /><br />As an adult, I used to wake up at 4 a.m. with nonstop sneezing and dripping eyes. I'd take an antihistamine and eat something and I'd be better in about 30 minutes.<br /><br />After I was Dx'd with type 2 diabetes in 1996, my allergies disappeared. I lost weight, but not on a LC diet. But I kept reducing carbs until I was pretty LC after a year or so.<br /><br />This summer I've had terrible allergies again. I haven't gained weight. I'm not eating carbs.<br /><br />So I think there's more to this than LC diets and losing weight. Maybe the hot, humid weather has allowed more mold to grow.Gretchenhttps://www.blogger.com/profile/17019921800841883073noreply@blogger.comtag:blogger.com,1999:blog-8859456735165996893.post-15420054107332613512010-08-05T06:29:21.701-07:002010-08-05T06:29:21.701-07:00Hi Pål.

It was an eye opener. Since then, reductions in inflammation derived symptoms are one of most striking results I see in people cutting carbs.

My theory is that a major contributor to the rise in allergy rates, along with those you mention, is the increase in omega6/rancid oils in our diet. McDonalds switched from beef tallow to "vegetable" oils in 1990 for all their frying needs. Billions were then served rancid, oxidized oils. If I were a bettin man, that's where I'd lay down my money. Or at least the one-two punch of that plus the spike in HFCS consumption that accompanied it.Aaron Blaisdellhttps://www.blogger.com/profile/17204484453346358921noreply@blogger.com
