A new study published in the European Review for Medical and Pharmacological Sciences has revealed something quite counterintuitive about chocolate, one of the world’s most prized ‘high-fat’ foods.  This strangely medicinal ‘sweat treat,’ which ironically you find in the candy aisle at the pharmacy, improved markers of cardiovascular disease, including the reduction of belly fat, and only after one week of consumption.

Researchers from the Department of Neuroscience, Division of Human Nutrition, University of Tor Vergata, Rome, in a paper titled ‘Effects of dark chocolate in a population of Normal Weight Obese women: a pilot study,’ describe the effects of 100 gram of dark chocolate taken for one week (approximately a 3 ounce bar) in so-called ‘normal weight obese (NWO)’ syndrome subjects.

NWO syndrome is defined as ‘an excessive body fat associated with a normal body mass index and characterized by a higher risk for cardiovascular morbidity and mortality,’ and has been found to be associated with a 2.2 fold increased risk of cardiovascular mortality in women compared with those with low body fat.[1]  Generally, those with NWO have 30% or more total body fat mass percentage and significantly higher values of proinflammatory cytokines such as IL-1, IL-6, IL-8 and TNF-α.[2] [3] [4]

The study looked at the effects of dark chocolate consumption on the following:

  •   Blood lipid profiles
  •   Biochemical parameters (e.g. interleukins)
  •   Blood pressure
  •   Abdominal circumference (i.e. ‘belly fat’)

A modest sample size of 15 women with NWO syndrome, aged 20-40 years, were included in the study. They received 100 grams of dark chocolate (DC) containing 70% cocoa for 7-days. Dual energy-X-ray absorptiometry (DXA) was used to measure body composition. Blood pressure, anthropometric measurements, biochemical parameters and plasma levels of some cytokines were measured before and after DC consumption.

The results were described as follows:

After DC [dark chocolate] consumption, we observed a significant increase in the HDL cholesterol level (Delta% = +10.41±13,53; p ≤ 0.05), a significant decrease of total cholesterol/HDL cholesterol ratio (Delta %= -11.45±7.03; p ≤ 0.05), LDL/HDL cholesterol ratio (Delta % = -11.70±8.91; p ≤ 0.05), and interleukin-1 receptor antagonist (IL-1Ra) (Delta % = -32.99±3.84; p ≤ 0.05). In addition, a reduction in abdomen circumference was observed. We also found a positive correlation between changes in atherogenic indices, and IL-1Ra, abdomen reduction.

The authors concluded:

Our findings suggest that regular consumption of DC could be useful in maintaining a good atherogenic profile, due to the favorable effects on HDL cholesterol, lipoprotein ratios and inflammation markers.
