Does a Dark Chocolate a Day Really Keep the Doctor Away?

Many people think of dark chocolate as something their mothers used to bake with, but it has come a long way since that time in terms of texture and flavor. Many varieties of dark chocolate are on the market, with some tasting better than others. I myself was a big milk chocolate fan and when the research became clear that dark chocolate was the most advantageous I reluctantly transitioned myself over to the dark. However, after going over to “the other side” I am now sold on dark chocolate.

If you only like milk chocolate consider trying Dove Dark Chocolate Promises – they come in a nice bite size and 2 per day is a good serving. Experiment with tasting different ones. Trader Joe’s has Dark Chocolate Wedges that come in a small round tin n regular dark chocolate and spiced with chipotle for a nice kick. My current favorite is Kallari dark cocoa which comes in 70, 75 and 85% at Whole Foods. Kallari has a rich smooth taste that I only experienced with dark chocolate I tasted in Switzerland. Choose ones that are greater than 70% cocoa since a higher cocoa content contains the most nutrients and the least amount of sugar.

Why eat dark over milk chocolate? Dark chocolate contains higher amounts of a type of phytochemcial (a chemical naturally found in foods that prevents disease) called flavanols than milk chocolate. The higher the percent cocoa the more flavanols the chocolate contains. Dark chocolate and cocoa contain several types of flavonoids called catechins and epicatechins which are thought to lower inflammation in the body.

Dark chocolate has been linked with lower inflammatory states in the body due to its high antioxidant activity. A 2008 study done with 5000 people linked a square or two of dark chocolate per day with 33 percent decrease in heart disease among women and a 26 percent decrease in men. The people in the study had lower levels of C - reactive protein, a marker in the blood that signals inflammation in the body.

It is recommended to eat one ounce of dark chocolate per day for health - I’d say a recommendation most of us can live with – and maybe not even a splurge, but a necessity!

Vitamin D: The Wonder Vitamin?

This fat-soluble “sunshine vitamin” has recently re-emerged as the wonder vitamin with numerous research studies coming out monthly on its health benefits.

Until very recently, it was thought that the RDA for Vitamin D (400 IU/day) was sufficient to prevent disease and to maintain bone health. We have recently seen an epidemic of vitamin D deficiency in this country, which is thought to be responsible for many autoimmune diseases such as rheumatoid arthritis and Multiple Sclerosis, cancers and even cardiovascular disease.

What are the recent findings on Vitamin D?

In January 2009 researchers from the University of Cambridge and the University of Michigan Peninsula Medical School revealed that compared to those with optimum Vitamin D levels, those with the lowest levels were more than twice as likely to be cognitively impaired – i.e. have dementia

In February 2009 the Archives of Internal Medicine studied 19,000 adults and adolescents. People with the lowest average levels of Vitamin D were 40% more likely to have a recent respiratory infection compared to those with higher Vitamin D levels

In March 2009 the Journal of Nutrition published research showing that high intakes of both calcium and Vitamin D helped protect against diabetes. C-peptide (a measure that determines if diabetes is in the works) was 20% lower in those with higher blood levels of Vitamin D

In April 2009 the American Journal of Clinical Nutrition published research showing that a daily supplement of 83 mcg. of Vitamin D per day (or 3320 IU) significantly boosted heart health by lowering triglyceride levels (storage form of fat) and markers of inflammation in the blood that indicate heart disease

In June 2009 the National Institutes of Health funded a study that showed that higher blood levels of Vitamin D were linked to increased loss of abdominal fat

Benefits of vitamin D are more important than we all knew – lowering risk of heart disease, respiratory infections, dementia, and diabetes and helping with weight loss!

A great way to get your vitamin D, besides food, is exposure to daylight or sunshine three times per week for about 10-15 minutes, since your skin has the ability to manufacture it after being exposed to sunlight. Since many of us try to stay out of sun due to skin cancer, we are deficient in natural vitamin D. However, it is still important to wear your sunscreen.

Some researchers are now calling Vitamin D the antibiotic vitamin since it boosts protection in the white blood cells of antimicrobial compounds that defends the body against germs. Many physicians are recommending intakes of 1000-2000 IU of Vitamin D per day to help with already low tissue levels and increasing the tissue levels to help prevent disease.

Next time you visit your physician ask to have your Vitamin D levels checked to know if you are in need of supplementation – it could save you more than just a cold!
