Spaniards usually eat dinner between 9pm and 11pm, and this world-famous feature is actually harmful to cardiovascular health. A European study of more than 100,000 people in France showed that people who ate dinner after 9 p.m. had a 28% increased risk of stroke. Breakfast time in the morning and evening has a similar effect. The study has been published in the international journal Nature Communications. The British "Daily Mail" 14**, the study was conducted by a number of academic institutions in France and Spain, and investigated the meals of 103,389 people in the French "Nutrinet-Santé Study" (Nutrinet-Santé Study) for 7 days a week. 
One-third of the respondents ate dinner before 8 p.m., which was the earliest group to eatDinner after 9 p.m. also accounted for one-third of the population. According to an average follow-up survey of 7 years, there are about 2,000 cases of cardiovascular diseases such as heart disease and stroke among more than 100,000 people. Transient ischemic attack (TIA), commonly known as mini-stroke, was 28 percent more likely to occur in those who ate dinner after 9 p.m. than those who ate dinner before 8 p.m. There was no difference in the risk of coronary heart disease. 
Digesting food raises blood sugar and blood pressure. Blood pressure is usually low at night, and rising blood pressure during this time can damage blood vessels and increase the chance of blood clots, which can lead to strokes and heart attacks. Dr. Bernard Srour of the University of Sorbonne Paris Nord, the study's lead author, said his grandmother used to warn him not to be too late for dinner, and the study concluded that his grandmother's advice might have some merit. However, in today's 24/7 society, people often feel that there is not enough time, and many people often eat dinner late in the morning, and people who think they are too busy to eat dinner earlier may have an increased risk of health problems, which is more common in women, but further research is needed. Nearly 80% of the people surveyed in this study were women. 
The results of the study showed that for every 1 hour delay in eating dinner, the risk of stroke or mini-stroke increased by 8%. There is also a risk of eating breakfast too late, with a 6% increased risk of cardiovascular disease for each 1-hour delay in eating, for example, a 10 a.m. breakfast person who eats breakfast at 10 a.m. has an 18% increased lifetime risk of cardiovascular disease compared to someone who eats at 7 a.m. 
The risk of stroke or mini-stroke decreased by 7% for each additional hour of uneaten time between dinner and breakfast the next day, but only if the dinner was eaten earlier and the fasting time was extended before breakfast the next day, rather than if the dinner was eaten too late and breakfast the next day. An important outcome of note for men was an 11% increased risk of coronary heart disease for every 1-hour delay in eating breakfast.
