Nutritional Concepts Mid-Week Brief
September 3, 2014
Dear Valued Subscriber,

Did you know that according to a study in the most recent issue of Journal of the American Board of Family Medicine, the recommended daily allowance for vitamin D is grossly inadequate for correcting low serum vitamin D levels in adults? They say 5000 IU vitamin D3/day is usually needed to correct deficiency, and the maintenance dose should be equal to or more than 2000 IU/day

Steve: This is much different (and much more accurate) than what the Institute of Medicine recommends. While a positive step, we know that it does not go far enough. There are much quicker ways to raise vitamin D levels than even what the ABFM recommends.

Given the importance of vitamin D for dementia and Alzheimer's disease alone, major medical organizations need to get this right. 


Have a happy, healthy week. Bonnie and Steve Minsky

Low Carb Beats Low Fat in Study.

Bonnie: Should there still be a debate about which style of eating is better for body mass reduction and cardiovascular disease risk: low carb or low fat? A government funded study appearing in the Annals of Internal Medicine says low carb produces better results.


While it may be a surprise to some, this should simply be reaffirmation for you. We tend to get carried away when one study lauds the benefits of a certain diet. Let's not do so here.


Low carb does not mean "no carb". If we ate no carbohydrates, we would all be walking around like a bunch of zombies. Low carb means that we should be choosy with the carbohydrates we consume. For example, choosing predominately fruit and vegetables is the right way to consume carbohydrates. Lessen the amount of grain carbohydrates and eliminate refined carbohydrates altogether. Get the idea?


The real shame is that fat has been unnecessarily vilified for decades. You have known for a while now that healthy fat is good, and even saturated fat in moderate amounts is ESSENTIAL for optimal body function. Unfortunately, many others have been misled.


Here are some of the highlights of the study, which was performed on healthy subjects (yeah!):

  • At 3, 6, and 12 months, the low carb dieters had lost significantly more weight than the low-fat dieters.
  • At the end of one year, the low carb group had lost about 12 pounds, whereas the low-fat group has lost only 4.
  • The HDL ("good") cholesterol levels rose more sharply in the low-carb group.
  • The HDL-to-total cholesterol ratio also rose more sharply in the low-carb group.
  • Those in the low carb group had greater increases in lean muscle mass, where as those in the low-fat group lost more muscle compared to fat.
  • Those in the low carb group had greater decreases in C-reactive protein (CRP), a measure of inflammation, than those in the low-fat group.

Yes, you can crack a smile. You're doing the right thing!

Mold, Mold Everywhere

In many parts of the country, mold spore levels are at their highest. If you can track the mold counts, avoid mold cross-reacting foods and beverages, and install whatever mold-prevention measures that work for you, getting through the season is possible.


However, when you are unaware that mold is in your home or workplace, you have no chance, and it can be highly detrimental to your health if you are mold allergic, have a yeast overgrowth or candida.


Researchers in the Journal of Allergy and Clinical Immunology have found that the presence of several types of mold can lead to breathing problems in asthma sufferers, as well as increasing the likelihood of developing the condition.


Approximately 10 mold varieties exist in a typical home, with aspergillus and the antibiotic-producing Penicillium the most common.


Characterized by typically high humidity, homes with poor heating and ventilation allow mold to proliferate. Dampness is the major factor affecting the growth of mold inside homes, highlighting the need for homes to properly maintained.


Here are tips for what you can do to curtail mold exposure: This is available to NCI Well Connect subscribers.
