Brie for Breakfast

Welcome to the European Breakfast Buffet.  Calcium rich foods are featured in cheeses and yogurts.  At least 3 choices of cheeses on a rotation from day to day.  Yogurt comes plain, with dollops of fruit compote, and prepackaged Yoplait and competitors.  Milk is skim, whole, almond, walnut.

Cheeses are featured again at the luncheon buffet.  Capri salad of sliced Mozzarella, tomato, and garnish is a popular alternative to other salads with Feta or Goat Cheese.  Further north Gouda, Emmentaller, Cheddar, Jarlesberg step forward.

After dinner, after dessert, the cheese plate, often with port or a dry red wine, finishes the meal.  Many Europeans consume 1000, 1200 or even 1500 mg calcium daily in foods.  This they have done for centuries.

Smoked Salmon is a constant at breakfast.  The best source of Vitamin D3 other than Cod Liver Oil.  Cod is the dominant fish in the Portuguese diet, along with Sardines, eaten whole, often bones and all, high in Calcium and D3.

Cured meats, sausages, and eggs are good sources of protein at every breakfast buffet.  Hearty whole grain breads are available, but are losing ground to chocolate filled puff pastries.

Traditional diets have persisted because they work.  They fulfill the nutritional needs of the peoples who have eaten them for generations.

Make sure your diet meets your nutritional needs for good bone health.  Calcium, Vitamin D3, Protein, and Vitamins & Minerals.  Take Control Naturally with proper nutrition.

Goodbye to “Totally Natural” Vitamin D

I was out at high noon (about 1:12 CDT) today, and may have made some Vitamin D in my exposed skin.  We had beautifully clear skies with cool, dry air and lots of sunshine.  I did not use sun-block for the few minutes of skin cancer risk.  Unfortunately, it was also only a few minutes of Vitamin D opportunity. 

Ultraviolet light is attenuated and eventually blocked by the atmosphere.  The lower the sun is on the horizon, the less UV light gets through.  In Waterloo, IA we are entering the 7 months of the year when the sun is too low on the horizon.  We do not get enough UV to produce any Vitamin D.

Less than half of Iowans, who do not take substantial Vitamin D3 supplements, have sufficient Vitamin D levels in September.  By early April, that is less than 15%.

Punxsutawney Phil saw his shadow today.  Six more weeks of winter.  But NINE more weeks before we can get ANY Vitamin D from the sun in Iowa.  Here the sun is high enough off the horizon only 5 months of the year.  Even in the summer very few Iowans make enough of their own Vitamin D.

In all of 2013 I saw fewer than ten patients with good vitamin D levels from only:  Multiple Vitamins & Minerals, Calcium Plus D Supplements, “Vitamin D Enriched” Milk, and Sunshine combined.  Every other patient needed an additional 1000 IU to over 5000 IU Vitamin D3 supplements daily.

Lies, Damn Lies and Statistics

Mark Twain and others have said:  “There are Lies, there are Damn Lies, and then there are Statistics”.  That is the danger when we use Statistics (Meta-Analyses) as a basis for “Evidence-Based” Medicine.  A recent meta-analysis looking at Vitamin D has reached a gaggle of questionable conclusions.  The news media have swallowed it hook, line and sinker, and want you to do so as well.

This meta-analysis re-analyzed 40 old studies which were not designed to track actual 25-hydroxy Vitamin D levels, and used doses of Vitamin D that we now know are too low to be effective.  They looked for diseases which were not specifically tracked, but might be mentioned as incidental findings.  None of these studies individually showed a “statistically significant” finding.  But if you combine enough different studies, the numbers become large enough that “statistical significance” can happen.
