Eating dinner late due to busy work or study can greatly increase the risk of cardiovascular diseases such as stroke and heart attack (acute myocardial infarction). There are quite a few people who fill their late dinners with instant foods such as ramen. [사진=게티이미지뱅크]A study has shown that eating breakfast and dinner late can significantly increase the risk of cardiovascular diseases such as stroke.

The French National Institute for Agriculture, Food and Environment (INRAE) announced that this was the result of a survey and analysis of more than 100,000 people who participated in the NutriNet-Santé cohort.

Studies have shown that delaying the first meal, including skipping breakfast altogether, increases the risk of developing cardiovascular disease, with the risk increasing by 6% for each hour delayed at mealtime. For example, people who eat their first meal at 9 a.m. have a 6% higher risk of developing cardiovascular disease than those who eat their first meal at 8 a.m.

Additionally, it was found that eating dinner late (after 9 p.m.) increased the risk of cardiovascular disease by 28% compared to eating dinner before 8 p.m. Women in particular are at higher risk. Additionally, it was analyzed that the longer the nighttime fasting time (the time between the last meal of the day and the first meal of the next day), the lower the risk of cardiovascular disease. The research team said, “It is better to eat the first and last meal of the day early.”

The research team analyzed the association between food intake patterns and cardiovascular disease using data from 103,389 participants (average age 42 years, 79% women). To reduce the risk of bias, we took into account various confounding factors, especially sociodemographic factors (age, gender, family situation, etc.), nutritional quality of diet, lifestyle, and sleep cycle.

According to research results from the Global Burden of Disease (GBD) group, cardiovascular disease is a major cause of death around the world, and the annual number of deaths due to cardiovascular disease (2019) is 18.6 million. Of these, approximately 7.9 million people die due to bad eating habits.

The daily cycle of alternating periods of food intake, such as meals and snacks, and fasting periods synchronizes the peripheral clocks (circadian rhythms) of various organs in the body, affecting metabolic functions such as blood pressure regulation. Cardiovascular diseases include stroke, heart attack (acute myocardial infarction), heart failure, atrial fibrillation, arrhythmia, and coronary artery disease.

The results of this study (Dietary circadian rhythms and cardiovascular disease risk in the prospective NutriNet-Santé cohort) were published in the international journal Nature Communications and introduced by the American health and medical media outlet MedicalXpress.
