As well as a healthy one diet it is also very important to be “allies” of the clock: those who eat breakfast and dinner early have less chance of contracting one of the cardiovascular diseases, reducing the risk of strokes and heart attacks. This was revealed by a study published in Nature lasted from 2009 to 2022 which examined over one hundred thousand people where the association between daily eating/fasting cycles with the so-called “peripheral circadian clocks” was demonstrated, i.e. the cyclical variations that every day involve our biological activities, which they directly participate in the regulation of the cardiovascular system.
The results
“The timing of meals and the number of occasions on which eating was estimated from repeated 24-hour dietary records,” explain the researchers from the French National Institute of Health and Medical Research (Inserm), the Sorbonne in Paris and the ‘Institute of Global Health of Barcelona. According to the study, consuming the first meal of the day late (after 9am instead of before 8am) and the last meal of the day after 9pm instead of consuming it before 8pm is “associated with a higher risk of cardiovascular outcomes, especially among women.
Expert advice
The study examined 103,389 participants, 79% of whom were women with an average age of 42.6 years: overall, the youngest participants (students or unemployed), without family histories of cardiovascular diseases, habitual smokers but athletes had the tendency to have breakfast and dinner later. In terms of percentages, delaying breakfast increases the onset of cardiovascular diseases by 6%, which reaches 8% if you dine too late in the evening. “Our results suggest a potential advantage in adopting earlier eating patterns and combining a longer overnight fasting period with an earlier last meal, rather than skipping breakfast, in the prevention of cardiovascular disease,” explain the scholars.
The numbers in the world
In short, to eat well we should be early risers and not stay too late in the evening. Cardiovascular diseases still represent the leading cause of death and disease in the world with almost 8 million deaths every year. The modern lifestyle made increasingly fast-paced, the lack of time in Western societies and the ever-increasing number of fasting practices that promote skipping meals “have led to poor nutritional behaviors, such as eating late at night and skipping breakfast”, explain the experts.
The daily cycle of eating and fasting synchronizes circadian rhythms in peripheral organs “including especially the liver but also the heart, kidneys and pancreas, and influences cardiometabolic functions including the regulation of blood pressure.” Chrononutrition is a new field in Nutrition Sciences of fundamental importance for explaining the relationship between the timing of food intake, circadian rhythms and the health of the human organism.
