One of my wife's pet peeves is when students in her cooking classes are so concerned about the amount of salt that she uses for seasoning meat and fish. We like fully-seasoned food. And, occasionally, we are reminded of the "dangers" of sodium by such students or others who "are only trying to help." But, I suspect that we actually consume less sodium than most. One thing that probably shocks people is the fact that we use a salt, Diamond Crystal Kosher (DCK), which looks larger than "normal" table salt. Two teaspoons of DCK has about the same amount (weight) of salt/sodium as table salt---DCK appears twice as large as an equivalent amount of table salt. I bet another reason for the surprise is that we season food from scratch. We rarely use prepared foods. And high-calorie foods like meat and fish requires a good bit of salt to make it taste good. Of course, if you buy prepared foods, this salt has already been added, so you never see the shocking act of adding the proper amount of salt.
</p>
<p>
But, what is a proper amount of sodium? The USDA tries to determine appropriate sodium levels as a function of "serving size", but I think this is ridiculous. Depending on the food, one might consume many servings of one type of food, but few of another. It seems to me that the closest thing we have to a constant in food is calories. People naturally balance the amount of calories they eat, probably due to fullness/hunger instincts. Different people eat different rates of calories, but each individual keeps a fairly constant calorie intake. They might over/under-eat over short periods (a day or two), but quickly return to their normal rate. So, I think the best way to define appropriate sodium intake is via calories. The USDA says the typical diet is 2000 calories/day and recommends no more than 2 grams of sodium/day. In studying various nutritional labels, this rate of 1 milligram of sodium per calorie seems quite reasonable. Even foods we might think are high sodium, like <a href="http://nutritiondata.self.com/facts/snacks/5626/2">potato chips</a>, are fine. 100 grams of potato chips might look like a lot of sodium---388 mg. But, that is for 559 calories, or a rate of .69 mg sodium per calorie. You'll get full eating potato chips before eating too much sodium.
</p>
<p>
When my wife and I eat steak, we'll typically cook over 1 pound of meat. Here is the <a href="http://nutritiondata.self.com/facts/beef-products/3271/2">nutritional information for rib eye steak</a>, a cut we often eat when we eat steak (which is not that often). Note that 1 pound of this raw beef has 1243 calories, but only 254 mg of sodium. So, based on the 1 mg/calorie rule, it requires another 1000 mg of sodium. That's a <i>lot</i> of salt, especially considering that <a href="http://nutritiondata.self.com/facts/spices-and-herbs/216/2">salt</a> is only approximately 39% sodium---6 grams of salt (one teaspoon) has 2.3 grams of sodium. Note that salt is NaCl (sodium chloride); the atomic weight of Na is appx. 39% of the weight of Na and Cl. So, that pound of rib eye steak needs approximately 1 teaspoon of DCK salt. This looks like a lot to someone who mostly eats prepared foods. But, in fact, even the USDA wouldn't complain.
</p>
<p>
If you turn the lens on deli meats, you might be surprised for a good reason. We're visiting family and this morning, we had Oscar Mayer Deli Fresh Honey Smoked Turkey Breast. I was curious of the sodium content, so I took a look at the nutritional label. 470 mg of sodium per 50 calories, or 9.4 mg sodium per calorie. Egad! If you eat 2000 calories of this deli meat, you'll consume 18.8 <i>grams</i> of sodium. Apparently, this is <a href="http://nutritiondata.self.com/facts/sausages-and-luncheon-meats/7513/2">normal for conventional deli meat</a>. Of course, "all natural" deli meat might be different. Recall that 2 pounds of steak has almost 2500 calories, yet only requires 2500 milligrams of sodium to taste good. Of course, Oscar Mayer proudly advertises the fact that it is 98% fat free and low calorie (per serving). But, servings are silly and our obsession with "fat free" is ridiculous. Our bodies <i>need</i> a reasonable amount of fat and humans seem to get fat much more easily on a high-carb, low-fat diet than one which includes a reasonable amount of fat.
</p>
<p>
My deli meat sodium discovery makes me realize just how important it is to avoid prepared foods. I've known that recommendation to be important, but I didn't realize that prepared foods can have 9-10 times the reasonable level of salt (1 mg/calorie). When we prepare our own food, we are careful to add just enough salt to enhance flavor. We would never come close to adding the amount of salt that is found in conventional deli meat! Yet, when we eat prepared foods, whether in grocery stores or in restaurants, we don't see the amount of salt that goes into the food and hence aren't as careful. So, I think the advice <i>we</i> are given to be careful of our sodium intake is a bit silly---we see most of the salt that goes into your food and hence are naturally careful. I believe those that need to be careful are people who rely on prepared and restaurant food for the majority of their calorie intake.

It sounds funny, and a bit annoying, I know. But, hear me out.
</p>
<p>
For years, my wife experienced painful <a href="http://en.wikipedia.org/wiki/Urinary_tract_infection">urinary tract infections</a>. As (what seemed like) luck would have it, these would develop overnight and I'd end up driving her to the emergency room at 2am because it was too painful to stand.
</p>
<p>
She talked to various <a href="http://en.wikipedia.org/wiki/Obstetrics_and_gynaecology">ob/gyn</a> doctors about the problem, often receiving the standard, useless (to her) advice of wearing cotton underwear, keeping the area very clean, wiping from front-to-back after using the bathroom, avoiding tight-fitting pants, and drinking cranberry juice. She was given an antibiotic at each emergency room visit to temporarily fix the problem, but she hated having to rely on antibiotics. She couldn't believe it when one ob/gyn recommended a constant, low-dose antibiotic preventative treatment.
</p>
<p>
After much searching, one doctor suggested that she pee after sex. He said that pee is highly acidic and will likely kill any bacteria that is growing around the urinary tract. It sounded painful/difficult. The last thing you want to do after sex is get up, drink lots of water and wait on the potty until something comes out! But, UTIs were more painful, so she gave it a try. A few months passed and she diligently followed the doctor's suggestion. No UTIs.
</p>
<p>
A few months later, <i>I</i> came down with some sort of painful infection in my scrotum. Unlike my wife, I <i>hadn't</i> been peeing after sex. I saw my doctor, but he didn't any particularly useful advice, and the infection resolved on it's own after a few days. But, this infection convinced me that I ought to be joining my wife in the after sex ritual.
</p>
<p>
Now, it's been over three years since we've been committed to peeing after sex and neither of us have UTI or similar infections. I see that <a href="http://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0001549/">peeing after sex is a standard recommendation for UTIs</a>. But, it's somewhat buried. It'd be nice if they had some sense of the practical effectiveness, possibly organized by which strategies are more likely to work for different races, socioeconomic backgrounds, etc. 'course, that might alarm the political correctness police...

It seems like this is a standard summer vacation for all Boston-area families with small children like us. It's easy to see why. Our four-year-old daughter <i>loved</i> Storyland---Cinderella's castle, circus the flying whales, the twirling turtles and even the more scary rides like the Bamboo Chute.<br />
<br />
This morning, my mother-in-law put a take-out styrofoam container into the microwave to warm up left-over pancakes. My wife and I both cautioned this move, warning about the possibility of plastic chemicals leaching into the food. She said it was fine---they do it all the time without any ill effects. I was curious to find out the truth. A Google search returned <a href="http://www.health.harvard.edu/healthbeat/HEALTHbeat_081606.htm#art1">a consumer-oriented Harvard Medical School newsletter about exactly this issue</a>. The answer is "it depends". Not all styrofoam will leach chemicals in sufficiently large enough quantities to arouse concern. But, many of those containers are tested and labeled "microwave safe". In particular, single-use containers such as take-out styrofoam boxes are generally not known to be safe and should not be used in the microwave. Of course, the FDA is conservative with the "microwave safe" label, requiring 100-1000x less chemicals than have been shown to harm laboratory animals over a lifetime of use. So, occasionally eating food out of microwaved take-out styrofoam boxes <i>might</i> be okay, but it's not clear and it's not a risk I'm willing to take.<br />

It was from an email "forward" which claimed that it was given by Kurt Vonnegut in a commencement speech. I recently discovered that, in fact, it was a <a href="http://www.chicagotribune.com/news/columnists/chi-schmich-sunscreen-column,0,5909206,full.column">Chicago Tribune newspaper column by Mary Schmich</a>---the graduation speech she'd give if she were ever invited to give one. <a href="http://en.wikipedia.org/wiki/Wear_Sunscreen">Wikipedia provides full details about "Wear Sunscreen"</a>.<br />
</p><p>I enjoyed this pho-graduate-speech and thought that it contained excellent advice. At the time, I didn't think seriously about the "wear sunscreen" advice---I'm fair skinned and it seemed essential for avoiding burns even though I sometimes ignored the advice of my parents to apply it liberally and regularly. But, more recently, I've wondered whether "wear sunscreen" is really such great advice. Sunscreen blocks UVB rays which are used by the body to produce Vitamin D. About a year ago, I learned that <a href="http://health-for-humans.blogspot.com/2010/07/i-am-vitamin-d-deficient.html">I am Vitamin D deficient</a> and could use <i>more</i>, not less, UVB rays. Furthermore, sunscreen interacts with skin in ways that may increase the chances of skin cancer; and, sunscreen only partially blocks UVA rays which penetrate more deeply than UVB and have more potential to damage skin cells. These concerns are well-documented in the <a href="http://en.wikipedia.org/wiki/Potential_health_risks_of_sunscreen">Wikipedia article on the potential health risks of sunscreen</a>. One fact I did not know about is that increased sunscreen usage is positively correlated with skin cancer rates. Sunscreen is effective at preventing sun<i>burn</i>, but there is no evidence that sunscreen prevents skin cancer. If anything, evidence points in the opposite direction, that using sunscreen increases your chances of getting skin cancer. See, for example, <a href="http://ajph.aphapublications.org/cgi/reprint/82/4/614">Could Sunscreens Increase Melanoma Risk?</a> and <a href="http://www.sciencedirect.com/science/article/pii/S0091743583710108">Beneficial Effects of Sun Exposure on Cancer Mortality</a>.<br />
</p><p>As usual, it seems that the best approach here is moderation. Wearing sunscreen may be dangerous, but repeated severe sunburns are definitely dangerous (if not extremely uncomfortable). Some sun exposure when the sun angle is large enough to provide significant UVB (only in spring/summer around noon in Boston) is greatly beneficial. But, so much that it causes burns is undesirable. It seems that the best approach is to get a small amount of sun as many days as possible, but limit the amount of time you spend in direct sunlight each day. In cases where you know you are going to be in the sun for extended periods of time, the best approach may be to use a full-spectrum sunblock which minimizes the amount of UVA, UVB and infrared light which reaches your skin.<br />

My nose was stuffed, my throat hurt and I felt a bit crappy. Fortunately, it didn't last long. By Monday, I could feel it lifting. But, all that <a href="http://en.wikipedia.org/wiki/Mucus">mucus</a> my body generated during the cold was stuck somewhere in my upper respiratory system, most likely my <a href="http://en.wikipedia.org/wiki/Paranasal_sinus">paranasal sinuses</a>. As of Tuesday, I could barely speak and my throat hurt. Wednesday morning after taking a 12-hour <a href="http://en.wikipedia.org/wiki/Pseudoephedrine">Pseudoephedrine</a> the previous night, I had bloody (not to mention green) mucus out of my mouth and nose; it cleared-up quickly, but it was my first hint that I had progressed to a <a href="http://en.wikipedia.org/wiki/Sinusitis">sinus infection</a> and past a plain cold.<br />
</p><p>My dad had gargled with salt water when I was a kid, so I gave that a try. I later learned that <a href="http://www.nytimes.com/2010/09/28/health/28real.html">gargling with salt water can lessen congestion</a>. My dad had an awful time with his sinuses when he was younger, once having to have surgery to clear out a serious sinus infection. His advice to me was to use a saline nasal spray and decongestant medicine to prevent a cold from becoming a sinus infection. That sounds like good advice to me. I used allergy medicines, like <a href="http://en.wikipedia.org/wiki/Cetirizine">Cetirizine</a>, and expectorants, like <a href="http://en.wikipedia.org/wiki/Guaifenesin">Guaifenesin</a>. I think a regular decongestant would have done a better job of clearing out the mucus. Allergy medications are good at drying-out my upper respiratory tract, but don't clear out existing mucus. I think Guaifenesin was a mistake as I later realized it works best on chest congestion, which I didn't have. Here's hoping that the nasal spray plus decongestant recipe works better the next time I get a serious cold.<br />

A few months prior I had learned that my <a href="http://en.wikipedia.org/wiki/Nummular_dermatitis">nummular eczema</a> may be due to a Vitamin D deficiency. I had long wondered why the lesions were worse in the winter and all-but-disappeared in the summer. The Vitmain D test came back a bit below the "normal" range and my doctor recommended that I take a 1000 IU Vitamin D supplement.<br />
</p><p>I was pleasantly surprised to find a <a href="http://www.nytimes.com/2010/07/27/health/27brod.html">NYTimes article highlighting the scope of the Vitamin D problem</a>. It seems to be quite widespread and serious; and not enough is being done to raise awareness and compensate for our lack of UVB exposure due to sunscreen and jobs and lifestyles which rarely take us outdoors during the peak exposure hours (10am-3pm).<br />
</p><p>I'm quite happy to have solved one more piece of the puzzle known as my body and I hope awareness continues to build. If you've never been tested for Vitamin D, consider asking your doctor to test you for it in your next visit.<br />

I visited him about a month ago with gastrointestinal discomfort and unexpected weight loss. He ran a battery of tests including for TSH. My level was low, indicating that I may be producing too much thyroid hormones (<a href="http://en.wikipedia.org/wiki/Thyroxine">thyroxine (T<sub>4</sub>)</a> and <a href="http://en.wikipedia.org/wiki/Triiodothyronine">triiodothyronine (T<sub>3</sub>)</a>). I was worried that this might have been a result of me not getting enough <a href="http://en.wikipedia.org/wiki/Iodine">iodoine</a> because my wife and I eat most of our meals at home using <a href="http://www.diamondcrystalsalt.com/Culinary/Products/Kosher-Salt.aspx">Diamond Crystal Kosher Salt</a> which does not contain iodine unlike table salts. My doctor said he'd expect the reverse since iodine is required to produce the thyroid hormones. So, if I were low on iodine, he'd expect low levels of thyroid hormones which would cause the <a href="http://en.wikipedia.org/wiki/Hypothalamus">Hypothalamus</a> to produce more TSH and result in a high TSH test result. He did blood work today to do a full battery of thyroid tests. I'll report back when I find out the results.<br />

I've been using Biotene toothpaste and mouthwash for just under a month now. Since starting Biotene, I've had two <a href="http://en.wikipedia.org/wiki/Aphthous_ulcer">canker sores</a> on my lower-left lip. The first appeared after I ate hot, acidic food (pizza), so I gave Biotene a pass. The first has since gone away. But, when a second sore appeared, I wasn't willing to wait any longer. When using <a href="http://www.viewpoints.com/Trader-Joes-Peppermint-Toothpaste-reviews">Trader Joe's peppermint toothpaste</a> over the past 3-4 years (and eating a wide variety of foods), I've seen canker sores very rarely and <i>never</i> two in such close time proximity. I suspect that the problem is the detergent in the Biotene toothpaste (Isoceteth-20), but also wonder about the mouthwash, which contains <a href="http://en.wikipedia.org/wiki/Propylene_glycol">propylene glycol</a>. Propylene glycol is a possible cause of <a href="http://en.wikipedia.org/wiki/Contact_dermatitis">contact dermatitis</a>.<br />
</p><p><b>Update 7/14</b>: My remaining canker sore is almost completely healed 2 days after I switched from Biotene back to <a href="http://health-for-humans.blogspot.com/2010/06/trader-joes-peppermint-toothpaste.html">Trader Joe's toothpaste</a>.<br />

He was very nice and walked me through the current status of my gums and the possible actions which can be taken. He also gave me a little tour of my mouth and gums. My upper gums are in good shape. He noticed no bleeding, swelling or recession. My lower gums aren't bad. He identified two teeth with recession, the two first <a href="http://en.wikipedia.org/wiki/Premolar">bicuspids</a>. The recessions are 1 mm (left) and 2 mm (right). He told me about the different parts of the gum. The lower, soft tissue and the upper, firm tissue. Most of my front, lower teeth have lost their firm gum tissue, though my canines are still okay. My upper teeth still have a good amount of the firm gum tissue. He told me about three similar invasive approaches:<br />
<ol><li> transplant mouth roof surface skin on top of existing gum - he said this was the most traditional action and takes 10-12 days to fully recover<br />
<li> transplant mouth roof underneath skin under existing gum - this increases bulk of the existing firm gum<br />
<li> use cadaver skin under existing gum - same as #2 except using skin from a dead body<br />
</ol>Dr. Freedman said that my current condition is mild and it would be perfectly reasonable to wait and observe. This is the option I chose. Slightly frustrating was the fact that he didn't think there was much I could do to prevent the problem from getting worse. He said to continue my usual brushing. He said to continue to use a very soft brush and to not press hard when brushing. He also suggested to not overthink teeth and gum care. I'm not sure I can do that :-)
</p><p>I'm guessing I won't see tremendously different advice from another periodontist. I'm planning to see a different dentist for my next check-up. At least I'll get another opinion on whether I can do anything to help the situation. For now, I've eliminated sugary carbonated beverages (Coke), greatly reduced my acidic liquid consumption (black tea) and am trying a toothpaste and mouthwash that are supposedly good for dry mouth (my mouth dries out overnight). Dr. Freedman said I can't do anything to get the gum tissue to regrow, but I'd like to at least know what I can do to minimize gum loss.

When I realized 4 years ago that my canker sores might have been caused by an ingredient in most toothpastes (<a href="http://en.wikipedia.org/wiki/Sodium_lauryl_sulfate">sodium lauryl sulfate</a>), I went searching for a toothpaste without SLS. Trader Joe's Peppermint toothpaste was the <i>only</i> one I found! Granted, I didn't do an exhaustive search. But, it is somewhat amazing the extent to which SLS infiltrates toothpaste ingredients. Even "natural" toothpastes, like Tom's of Maine, use SLS. TJ's toothpaste is baking soda (<a href="http://en.wikipedia.org/wiki/Sodium_bicarbonate">sodium bicarbonate</a>) based and is apparently much gentler on the gums than normal toothpastes. I went from having 10+ painful canker sores per month (often multiple at the same time) to one mild sore every few months. It took about a year to see the full effect, though I saw a significant decrease in canker sores after a month.<br />
</p><p>Based on <a href="http://lifegoggles.com/2874/trader-joes-all-natural-peppermint-toothpaste/">this post</a>, I'm not alone in praising TJ's toothpaste.<br />

My dentist has always focused me on the usual brushing/flossing/fluoride. I first learned that this was a poor recommendation after discovering that it was the <a href="http://en.wikipedia.org/wiki/Sodium_lauryl_sulfate">sodium lauryl sulfate (SLS)</a> (a cheap <a href="http://en.wikipedia.org/wiki/Detergent">detergent</a>) in most brand-name toothpastes which was irritating my gums resulting in <a href="http://en.wikipedia.org/wiki/Aphthous_ulcer">canker sores</a>. At my latest checkup, I got a pretty serious scare---my lower gums had receded so far that my roots were exposed in places. I now realize that this is why they've been more sensitive than the other teeth, especially to hot and cold. What did my dentist recommend? More fluoride (and a visit to the <a href="http://en.wikipedia.org/wiki/Periodontology">periodontist</a>). Somehow, I don't think more fluoride is going to help considering that I already brush twice daily with fluoride toothpaste. 'course, it turns out that sodium lauryl sulfate is a cause of receding gum according to Wikipedia. Why hasn't anyone sued the <a href="http://www.ada.org/">ADA</a> and toothpaste manufacturers yet?<br />
</p><p>In addition to seeing a periodontist, I'm also quitting Coke (used to do 1 can/day) and seriously scaling back my tea drinking (was ~6 cups/day and I've learned that the tannin in tea translates to acidity which teeth and gums don't like). Besides sugar and acid, I'm guessing that such drinks lessen the opportunities for my <a href="http://en.wikipedia.org/wiki/Saliva">saliva</a> to protect and heal my teeth and gums. I've also learned that I probably have a minor case of <a href="http://en.wikipedia.org/wiki/Xerostomia">dry mouth</a>, which again means that I don't get as much of the natural protection from<br />
saliva as one normally would. One thing I'll be trying is <a href="http://www.biotene.com/Products/Toothpaste.aspx">Biotene toothpaste</a>, which adds enzymes to the mouth and doesn't contain SLS. One of the things I like about Biotene is that it contains <a href="http://en.wikipedia.org/wiki/Xylitol">Xylitol</a> which has been show to reduce <a href="http://en.wikipedia.org/wiki/Dental_caries">dental cavities</a>.<br />
</p><p><b>Update 6/21/10</b>: Biotene toothpaste does contain a detergent, <a href="http://en.wikipedia.org/wiki/Isoceteth-20">Isoceteth-20</a>.<br />
</p><p><b>Update 6/21/10</b>: A peer of mine at work discovered that the cause of her gum recesion was nighttime <a href="http://en.wikipedia.org/wiki/Bruxism">teeth grinding</a> at night. A teeth guard solved her problem.<br />
