The modern lifestyle of Western societies has given rise to specific eating habits, such as eating late dinners or skipping breakfast.
Health.- The time at which we eat could affect the development of cardiovascular risk diseases, especially breakfast and dinner, so it is recommended that they not be left until too late.
In addition, a longer overnight fast is associated with a lower risk of cerebrovascular diseases, such as stroke.
This study, carried out on a sample of 103,389 participants from the French cohort NutriNet-Santé, 79% of whom were women, with a mean age of 42 years, and who were followed between 2009 and 2022 to study associations between food intake patterns and cardiovascular diseases.
Increased risk per hour of delay
The results reflect, as reported by ISGlobal, that eating the first meal of the day later (such as when skipping breakfast) is associated with a greater risk of cardiovascular disease, with a 6% increase in risk per hour of delay.
As for dinner, eating it late (after 9 p.m.) is associated with a 28% increased risk of cerebrovascular diseases, such as stroke, compared to eating before 8 p.m., especially in the women.
On the other hand, a longer duration of overnight fasting – the time between the last meal of the day and the first meal of the next day – is associated with a lower risk of cerebrovascular disease, which supports the idea of eating the first and last meals of the earliest day.
Results that suggest that “adopting the habit of eating the first and last meals earlier with a longer period of overnight fasting could help prevent the risk of cardiovascular diseases.”
These conclusions, explains the research center, must be reproduced in other cohorts and through additional scientific studies with different designs.
Cardiovascular diseases, the first cause of death
Cardiovascular diseases are the leading cause of death in the world, according to the Global Burden of Disease study, with 18.6 million deaths annually in 2019, of which around 7.9 are attributable to diet.
The modern lifestyle of Western societies has given rise to specific eating habits, such as eating late dinners or skipping breakfast.
In addition to light, the daily cycle of food intake (meals, snacks, etc.) alternating with periods of fasting synchronizes the peripheral clocks, or circadian rhythms, of the different organs of the body, thus influencing cardiometabolic functions such as the regulation of blood pressure, explains ISGlobal.
Chrononutrition is emerging as an important new field for understanding the relationship between the timing of food intake, circadian rhythms, and health.
In the sample, to reduce the risk of possible bias, they took into account a large number of confounding factors, especially sociodemographic (age, sex, family situation, etc.), nutritional quality of the diet, lifestyle and sleep cycle.
