It is widely believed that eating dark chocolate is good for cardiovascular health. Some health and lifestyle experts, however, emphasized that there is no evidence for this fact. Recently, the British Journal of Nutrition published a new study, which supports regular consumption of chocolate. Before changing your diet to eat more chocolate and sweets, you should understand that this study is published based on clinical observation and available data.
According to the new study, the researchers from Luxembourg Institute of Health (LIH), university of South Australia, university of Warwick Medical School and university of Maine suggested that consuming a small amount of chocolate every day can help to prevent insulin resistance and type 2 diabetes. The study considered the data of 1,153 people between the ages 18 and 69. When comparing the health of various participants, the research group found lower insulin resistance and healthy liver enzymes in those who claimed that they ate around 100g of chocolate every day. Insulin resistance is one of the very important factors determining the onset of cardiovascular diseases.
The academic researchers proposed the hypothesis that chocolate can be useful for insulin sensitivity and liver enzymes. This study is conducted rigorously, noting down the lifestyle and diet preferences of the participants. The consumption of tea and coffee is also monitored. Both tea and coffee contain polyphenol which is useful to accelerate cardiometabolic effects of chocolate.
The visiting academic at the University of Warwick Medical School, and Scientific Director of department of population health at LIH, Prof Saverio Stranges said that cocoa based products can be suggested as dietary recommendation to improve cardio health and metabolism. However, he added that the results are simply observatory and more robust evidence based trials are required. He also emphasized that natural cocoa product is entirely different from highly processed commercial chocolates.
Among those who participated in the study, 80% of the individuals said that they eat at least 24.8g of chocolate every day. These people were active, young and had higher educational status compared to those who did not eat chocolate regularly. The principal investigator of the study, Dr. Ala's Alkerwi said that the people who consumed chocolate had significant socio-demographic profiles, better health access and healthy lifestyle habits. This can also be an important contributor for the reaction of the body to insulin and liver biomarkers.
Researchers have agreed that randomized control studies and additional observational research are required to truly understand how chocolate is useful in reducing insulin resistance and preventing disorders related to cardiometabolism.
