68455 Consuming more chocolates regularly may actually be more beneficial among teens who wish to lose weight and become slimmer, according to a new study.
Researchers from the University of Granada in Spain found that European adolescents who consumed more chocolates are slimmer compared to those who didn’t even if they weren’t really dieting or exercising. The researchers involved in the study looked at the eating and exercise habits of 1,458 adolescents between the age of 12 and 17.

Their research was a part of the HELENA study group, a group assigned to collecting and analyzing data about diets, fitness and other types of health measures among teenagers in Europe, according to Medical News Today. They found that those who consumed more chocolate had lower levels of overall body fat, regardless if they were dieting or exercising. These results were published in the journal Nutrition. The researchers also pointed out that chocolate has obvious health benefits. Chocolate is filled with antioxidants and may also be good for the heart and blood circulation.
However, the researchers failed to examine why chocolate consumption appears to help adolescents stay slim. Previous studies suggested that this may have something to do with flavonoids – a group of polyphenolic compounds known to have numerous beneficial biochemical and antioxidant effects in the body.
«It’s also possible that flavonoids in chocolate may decrease blood concentrations of bad cholesterol and reduce blood pressure,» says Dr. Susanna C. Larsson, of Sweden’s Karolinska Institute, where she and her team conducted a study of Swedish men that found chocolate consumption may also lower stroke risk. Critics have lamented that dark chocolate is good for the heart but Dr. Larsson expressed that surprisingly, 90 percent of chocolate eaten in Sweden and found in their study is milk-based.
68455 You might want to make a cup of hot chocolate to sip as you read this report: Researchers have discovered that chocolate lovers have less body fat, better heart health and even healthier blood pressure readings, reported Food World News on November 1.
Researchers from the University of Granada in Spain studied the diets and fitness levels of teenagers between 12 and 17. Those who ate the most chocolate had the lowest overall body fat. Their levels of exercise did not appear to influence the results.
In addition, the researchers discovered that the chocolate eaters had better blood pressure readings, healthier hearts and enhanced circulation.
Chocolate may provide these benefits because it contains flavonoids, reported Medical News Today on November 1. These polyphenolic compounds protect against cardiovascular disease through antioxidant, anti-clotting and anti-inflammatory properties.
«It’s also possible that flavonoids in chocolate may decrease blood concentrations of bad cholesterol and reduce blood pressure,» says Dr. Susanna C. Larsson, of Sweden’s Karolinska Institute, where she and her team conducted a study of Swedish men that found chocolate consumption may also lower stroke risk.
However, a nutrition scientist emphasizes that moderation is essential. Diets that deprive you of what you love, such as chocolate, don’t work as well as food plans that allow small treats.
«The key is to take a more relaxed approach and to have a little of what you like,» nutrition expert Janet Aylott explained.
One study showed that when dieters gave up all their treats, 65 percent of them gained weight rather than lost.
The newest chocolate study is supported by several previous studies:
University of Cambridge discovered that people who enjoyed chocolate every day were 29 percent less likely to have a stroke and 37 percent less likely to suffer with heart disease than those who avoided it most of the time.
University of California, San Diego found that chocolate-lovers have lower body mass indexes (BMIs).

68455 A moderate consumption of chocolate may have a positive effect on your body fat, according to a new study. Researchers from the University of Granada in Spain have discovered that in European adolescents, body fat levels tend to be inversely proportional to chocolate consumption. A survey revealed that the more chocolate a participant ate, the lower his or her body fat level was.
Published in the journal Nutrition, the study sought to investigate the relationship between chocolate consumption and various indicators of total and central body fat, such as body mass index (BMI). To do this, the study authors surveyed 1458 adolescents enrolled in the Healthy Lifestyle in Europe by Nutrition in Adolescents (HELENA) project – a multinational research effort that collects nutrition data from thousands of children between the ages of 12 and 17. The team then compared the participants’ estimated chocolate intake with their overall body fat profile.
According to lead author Magdalena Cuenca-Garcia, the results indicated that a higher consumption of chocolate corresponded to a lower level of total and central fat. The link persisted when the team controlled for total energy intake, sexual maturation, intake of saturated fat, coffee consumption, physical activity, and other factors known to influence body fat levels. Total and central fat levels were measured by skin folds, waist circumference, and bioelectrical impedance analysis (BIA).
«Our results demonstrate that a higher chocolate consumption was associated with lower total and central fatness in European adolescents,» the study authors wrote in the conclusion.
Several nutrients may account for the observed effect. For example, chocolate contains high levels of the flavonoid catechin, which has been linked to lower BMI levels in previous studies. According to the researchers, this compound is thought to promote healthy body fat levels by influencing cortisol production and insulin sensitivity.

But like all studies that rely on self-reported data, the current research project is not entirely conclusive, as its findings depend on the honesty of each participant. Earlier this year, researchers from the Arnold School of Public Health at the University of South Carolina discredited 40 years of nutrition research by showing that study subjects with higher BMI consistently misrepresented their overall caloric intake. By the same token, HELENA participants with higher body fat levels may have been more reluctant to report their actual candy and chocolate consumption.
In the end, moderation may be your best bet. «Chocolate can be good for you, as our study has shown,» the team concluded. «But, undoubtedly, excessive consumption is prejudicial. As they say: you can have too much of a good thing.»

68455 Un equipo de investigadores de la Facultad de Medicina y la Facultad de Ciencias del Deporte de la Universidad de Granada (UGR) ha desmontado científicamente la vieja creencia de que comer chocolate engorda. Ampliar foto En un artículo publicado esta semana en la revista ‘Nutrition’, sus autores han demostrado que un alto consumo de chocolate está asociado a niveles más bajos de grasa total (esto es, la grasa acumulada en todo su cuerpo) y central (abdominal), independientemente de si el sujeto practica o no actividad física y a la dieta que siga, entre otros factores. En este trabajo, los científicos analizaron si un mayor consumo de chocolate se asocia con un mayor o menor índice de masa corporal, así como otros indicadores de grasa corporal total y central en los adolescentes que participaron en el estudio Helena (Healthy Lifestyle in Europe by Nutrition in Adolescence). Se trata de un proyecto, financiado por la Unión Europea, sobre los hábitos alimentarios y el estilo de vida de los jóvenes de nueve países europeos, entre ellos España, informa la UGR en una nota. Los resultados de este estudio, en el que participaron 1.458 adolescentes de entre 12 y 17 años, mostraron que un mayor consumo de chocolate se asoció con niveles más bajos de grasa total y central, según lo estimado por el índice de masa corporal, el porcentaje de grasa corporal (obtenido a partir de plicometría e impedancia bioeléctrica, dos técnicas de medición) y el perímetro de cintura. Estos resultados fueron independientes del sexo, la edad, la madurez sexual, la ingesta energética total, la ingesta de grasas saturadas, fruta y verdura, el consumo de té y café, y la actividad física de los participantes. Como explica la autora principal de este artículo, Magdalena Cuenca García, aunque el chocolate está considerado como un alimento con un alto aporte energético (al ser rico en azúcares y grasas saturadas), «recientes estudios realizados en adultos sugieren que su consumo se asocia con un menor riesgo de trastornos cardiometabólicos». De hecho, el chocolate es un alimento rico en flavonoides (especialmente catequinas), que proporcionan múltiples propiedades saludables: «es un gran antioxidante, anti-trombótico y anti-inflamatorio, tiene efectos anti-hipertensivos y puede ayudar a prevenir la cardiopatía isquémica». Recientemente, otro estudio de carácter transversal desarrollado en adultos por científicos de la Universidad de California observó que una mayor frecuencia en el consumo de chocolate también se asocia con un menor índice de masa corporal. Además, estos resultados se confirmaron en un estudio longitudinal en mujeres que siguieron una dieta rica en catequinas. Este efecto podría deberse, en parte, a la influencia de las catequinas sobre la producción de cortisol y la sensibilidad a la insulina ambas, relacionados con el sobrepeso y la obesidad. Los científicos de la UGR han querido ir más allá, y analizar lo que ocurre con el consumo de chocolate en una edad tan crítica como la adolescencia controlando también por otros factores que pudieran influir en el acúmulo de grasa. El estudio, además de novedoso es quizás el más amplio y mejor controlado realizado hasta la fecha, y el primero en población adolescente. Contempla un número elevado de medidas corporales, una medida objetiva de la actividad física, detallado registro dietético mediante dos recordatorios no consecutivos de 24 horas con un programa informático basado en imágenes, y controla el posible efecto de confusión de un conjunto de variables claves. Los autores del artículo publicado en ‘Nutrition’ destacan que el impacto biológico de los alimentos no debe ser evaluado sólo en términos calóricos. «Las investigaciones epidemiológicas más recientes están centrando su atención en estudiar la relación entre determinados alimentos (no sólo por su contenido calórico, también por sus componentes) y los factores de riesgo para el desarrollo de enfermedades crónicas, incluyendo el sobrepeso o la obesidad». Con todo, los científicos de la Universidad de Granada insisten en la necesidad de ser moderados en el consumo de chocolate. «En cantidades moderadas, el chocolate puede ser bueno, como ha demostrado nuestro estudio. Pero un consumo excesivo resulta, sin duda, perjudicial. Como se suele decir: demasiado de algo bueno, ya no es bueno». Los investigadores de la UGR apuntan que sus hallazgos «tienen también importancia desde el punto de vista clínico, ya que contribuyen a entender los factores que subyacen en el control y mantenimiento del peso óptimo».

68455 A new research has found that consuming chocolates can actually help one shed off the extra kilos, as it speeds up the metabolism, which burns more calories.
Scientists from the University of Granada, Spain, discovered that people who ate large amounts of chocolate had far lower levels of fat, regardless of whether they lived an active lifestyle or had a healthy diet , the Daily Star reported.
One scientist said that the bottom line is that people who eat more chocolates have less of a problem with fat than those who don’t.
68455 Another study appears to find benefits from eating chocolate: researchers from the University of Granada in Spain analzying data on European teenagers found a strong link between high chocolate consumption and low levels of body fat.
Dr. Magdalena Cuenca-García, of the Department of Medical Physiology in Granada University’s School of Medicine, and colleagues report their findings in a recent online issue of the journal Nutrition.
The researchers are part of the HELENA study group, which is collecting and analyzing data about the diets, fitness and various health measures among European adolescents.
Previous studies have already found that regular chocolate consumption is linked to leanness in adults. There is also evidence that eating chocolate may reduce cardiovascular disease risk.
Eating chocolate ‘may help youngsters stay slim’Chocolate squares
Researchers from Spain have found that teens who eat chocolate have lower levels of total fat and fat around the middle than those who abstain.
The Spanish researchers decided to use the HELENA data to see if the same could be said of teenagers.
They analyzed records on 1,458 adolescents from nine European countries who were aged from 12 to 17 and who had completed computer-based questionnaires asking them to recall what they had eaten in the previous 24 hours on 2 non-consecutive days.
The records also contained information from which they could assess participants’ BMI, waist circumference, body fat measures and activity levels.
The results showed that higher chocolate intake among the teenagers was linked with lower levels of total fat and fat around the middle, regardless of other factors (including exercise).
The researchers in this study did not examine why chocolate appears to help the youngsters stay slim, but some previous studies have suggested it could be something to do with the flavonoids it contains.
Flavonoids are a group of polyphenolic compounds known to have numerous beneficial biochemical and antioxidant effects. For example, they appear to protect against cardiovascular disease through antioxidant, anti-clotting and anti-inflammatory properties.
«It’s also possible that flavonoids in chocolate may decrease blood concentrations of bad cholesterol and reduce blood pressure,» says Dr. Susanna C. Larsson, of Sweden’s Karolinska Institute, where she and her team conducted a study of Swedish men that found chocolate consumption may also lower stroke risk.
Many researchers say it is dark chocolate that is good for the heart, but Dr. Larsson says, surprisingly, that 90% of the chocolate eaten in Sweden – as they also found in their study – is milk chocolate.
