Why is Dark Chocolate Healthy?:
Chocolate is made from plants, which means it contains many of the health benefits of dark vegetables. These benefits are from flavonoids, which act as antioxidants. Antioxidants protect the body from aging caused by free radicals, which can cause damage that leads to heart disease. Dark chocolate contains a large number of antioxidants (nearly 8 times the number found in strawberries). Flavonoids also help relax blood pressure through the production of nitric oxide, and balance certain hormones in the body.

Heart Health Benefits of Dark Chocolate:
Dark chocolate is good for your heart. A small bar of it everyday can help keep your heart and cardiovascular system running well. Two heart health benefits of dark chocolate are:
* Lower Blood Pressure: Studies have shown that consuming a small bar of dark chocolate everyday can reduce blood pressure in individuals with high blood pressure.
* Lower Cholesterol: Dark chocolate has also been shown to reduce LDL cholesterol (the bad cholesterol) by up to 10 percent.
Other Benefits of Dark Chocolate:
Chocolate also holds benefits apart from protecting your heart:
* it tastes good
* it stimulates endorphin production, which gives a feeling of pleasure
* it contains serotonin, which acts as an anti-depressant
* it contains theobromine, caffeine and other substances which are stimulants
Doesn’t Chocolate Have a lot of Fat?:
Here is some more good news — some of the fats in chocolate do not impact your cholesterol. The fats in chocolate are 1/3 oleic acid, 1/3 stearic acid and 1/3 palmitic acid:
* Oleic Acid is a healthy monounsaturated fat that is also found in olive oil.
* Stearic Acid is a saturated fat but one which research is shows has a neutral effect on cholesterol.
* Palmitic Acid is also a saturated fat, one which raises cholesterol and heart disease risk.
That means only 1/3 of the fat in dark chocolate is bad for you.
Chocolate Tip 1 – Balance the Calories:
This information doesn’t mean that you should eat a pound of chocolate a day. Chocolate is still a high-calorie, high-fat food. Most of the studies done used no more than 100 grams, or about 3.5 ounces, of dark chocolate a day to get the benefits.
One bar of dark chocolate has around 400 calories. If you eat half a bar of chocolate a day, you must balance those 200 calories by eating less of something else. Cut out other sweets or snacks and replace them with chocolate to keep your total calories the same.
Chocolate Tip 2 – Taste the Chocolate:
Chocolate is a complex food with over 300 compounds and chemicals in each bite. To really enjoy and appreciate chocolate, take the time to taste it. Professional chocolate tasters have developed a system for tasting chocolate that include assessing the appearance, smell, feel and taste of each piece.
Chocolate Tip 3 – Go for Dark Chocolate:
Dark chocolate has far more antioxidants than milk or white chocolate. These other two chocolates cannot make any health claims. Dark chocolate has 65 percent or higher cocoa content.
Chocolate Tip 4 – Skip the Nougat:
You should look for pure dark chocolate or dark chocolate with nuts, orange peel or other flavorings. Avoid anything with caramel, nougat or other fillings. These fillings are just adding sugar and fat which erase many of the benefits you get from eating the chocolate.
Chocolate Tip 5 – Avoid Milk:
It may taste good but some research shows that washing your chocolate down with a glass of milk could prevent the antioxidants being absorbed or used by your body.Great news, heart sisters!  Turns out that our favourite guilty pleasure might actually be good for our hearts. Good news, heart sisters!

The Journal of the American Medical Association reported that dark chocolate (whose cocoa polyphenols contain nearly eight times the number of antioxidants found in strawberries) can help lower blood pressure through the production of nitric oxide, and also lower LDL (‘bad’) cholesterol levels in the blood by up to 10% from heart-health flavonoids in dark chocolate.

The ‘bikini approach’ to women’s health research

by Carolyn Thomas

We know that, until very recently, cardiac research for the past three decades has been done either exclusively on men, or with women represented in statistically insignificant numbers. Medical researchers have largely taken a ‘bikini approach’ to women’s health care – in which women’s health research focuses on breasts and the reproductive system.

In a recent WomenHeart interview, Mayo Clinic cardiologist Dr. Sharonne Hayes, founder of the Mayo Women’s Heart Clinic in Rochester, MN, explains:

“In the 1960s, erroneous assertions that heart disease was a man’s disease were widely spread to the medical community and to the public.  This led to research almost exclusively focused on cardiovascular disease in men.  Many clinical trials in the 70s and 80s excluded women or simply didn’t make an effort to enroll women in sufficient numbers to draw sex-based conclusions.” Continue reading “The ‘bikini approach’ to women’s health research”

Heart Disease 101 for new patients

Confused about heart disease terminology?  Visit my patient-friendly, no-jargon glossary of hundreds of confusing phrases, abbreviations and acronyms in cardiology.  Meanwhile, here are some basic definitions you need to know about women’s heart disease:

Heart disease (or cardiac disease) is any kind of disease that affects the heart, like:

  • heart failure
  • angina (any pain between neck and navel that typically comes on with exertion and goes away with rest)
  • arrhythmia (abnormal heart rhythms)
  • valvular heart disease
  • coronary artery disease (CAD) 

Cardiovascular disease (CVD) is not the same as heart disease.  Cardio refers to the heart and vascular refers to blood vessels.  CVD affects the heart and/or blood vessels: click to continue reading…
