Yes ladies, it’s time to crack open the bubbly and toast the University of Granada researchers from the Faculty of Medicine and the Faculty of Physical Activity and Sports Sciences. They have scientifically disproven the outdated belief that eating chocolate is fattening. If you don’t enjoy exercising, you may also appreciate that the research was independent of diet and physical activity.
Virtually everyone likes chocolate, and no other food resembles chocolate in flavour, aroma and texture. Chocolate is also highest on the list of foods subject to cravings which leads to guilt when we consume an excess.
In an article published this week in the journal Nutrition, the authors have shown that higher consumption of chocolate is associated with lower levels of total fat (fat deposited all over the body) and central fat (abdominal), independently of whether or not the individual participates in regular physical activity and of diet, among other factors.
The researchers determined whether greater chocolate consumption associated with higher body mass index and other indicators of total and central body fat in adolescents participating in the HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence) study. This project, financed by the European Union, studies eating habits and lifestyle in young people in 9 European countries, including Spain.
The pleasurable experience of eating chocolate can alter mood by directly producing a feeling of well-being and by distracting us from feelings such as anxiety and depression. In turn, relief from distressing mood states could reinforce liking for chocolate. These changes in mood could be related to any of the previous theories.
In a recent study by Dr. Penny Kris-Etherton of Pennsylvania State University, subjects who followed a diet rich in cocoa butter saw no rise in their blood cholesterol levels.
Independent of diet and physical activity
The study involved 1458 adolescents aged between 12 and 17 years and results showed that a higher level of chocolate consumption associated with lower levels of total and central fat when these were estimated through body mass index, body fat percentage–measured by both skinfolds and bioelectrical impedance analysis–and waist circumference. These results were independent of the participant’s sex, age, sexual maturation, total energy intake, intake of saturated fats, fruit and vegetables, consumption of tea and coffee, and physical activity.
As the principle author Magdalena Cuenca-Garcia explains, although chocolate is considered a high energy content food–it is rich in sugars and saturated fats–“recent studies in adults suggest chocolate consumption is associated with a lower risk of cardiometabolic disorders”.
In fact, chocolate is rich in flavonoids–especially catechins–which have many healthy properties: “they have important antioxidant, antithrombotic, anti-inflammatory and antihypertensive effects and can help prevent ischemic heart disease”.
Recently, another cross-sectional study in adults conducted by University of California researchers found that more frequent chocolate consumption also associated with a lower body mass index. What’s more, these results were confirmed in a longitudinal study in women who followed a catechin-rich diet.
The effect could be partly due to the influence of catechins on cortisol production and on insulin sensitivity, both of which are related with overweight and obesity.
Calorie impact is not the only thing that matters
The University of Granada researchers have sought to go further and analyse the effect of chocolate consumption at a critical age like adolescence by also controlling other factors that could influence the accumulation of fat. The research, which is both novel and, perhaps, the largest and best-controlled study to date, is the first to focus on the adolescent population. It includes a large number of body measures, objective measurement of physical activity, detailed dietary recall with 2 non-consecutive 24-hour registers using image-based software, and controls for the possible effect of a group of key variables.
In Nutrition, the authors stress that the biological impact of foods should not be evaluated solely in terms of calories. “The most recent epidemiologic research focuses on studying the relation between specific foods–both for their calorie content and for their components–and the risk factors for developing chronic illnesses, including overweight and obesity”.
Despite their results, the authors insist that chocolate consumption should always be moderate. “In moderate quantities, chocolate can be good for you, as our study has shown. But, undoubtedly, excessive consumption is prejudicial. As they say: you can have too much of a good thing”.
The University of Granada researchers stress that their findings “are also important from a clinical perspective since they contribute to our understanding of the factors underlying the control and maintenance of optimal weight”.
Some things to keep in mind when selecting a chocolate bar:
1) The darker the better
2) stay away from chocolate with soy, soy lecithin, palm oil, natural flavor, whey, yeast, polyglycerols and other nasty chemicals that don’t belong in the ingredient list
3) No refined sugar is necessary to make a great tasting chocolate bar 4) Cacao should be preferably stone ground and preferably organic (if it’s not raw the lower the antioxidant value)
5) cacao beans should NOT be gas dried (know your source).
