Be careful! Eating time disorders may increase the risk of heart disease

regular diet and sleep are essential for health.The heart is one of the most important organs of the human body and belongs to the center of the cardiovascular system and circulatory system. In recent years, with the change of living conditions and eating habits, heart health has been seriously threatened. According to statistics, about 17.5 million people die of heart disease each year, accounting for 30% of all deaths. Among them, China is the world's largest number of sudden cardiac deaths, nearly three quarters of people have cardiovascular problems.

While studies have shown that eating nutrients from healthy foods can be effective in preventing heart disease, a recent study presented at the American Heart Association's (AHA) 2020 virtual meeting suggests that eating time also plays an important role in maintaining heart health.The team, led by Nour Makarem, an associate researcher at Columbia University's Irvine Medical Center, looked at changes in mealtimes from weekday to weekend and found that the daily regularity of food intake was associated with important heart health risk factors, including waist circumference, body fat, blood pressure and blood sugar.At a virtual meeting of the American Heart Association (AHA) held last year, the team suggested that women who ate more calories at night tended to be at higher risk of heart disease, high blood pressure, excess body mass index (BMI) and worse long-term blood sugar control. On this basis, the new study further suggests that not only the timing of eating, but also the regularity of the diet is an important factor in the risk of heart disease.Based on the information currently released, the study involved 116 women of different races and ethnicities, aged between 20 and 64, from the AHA's Go Red for Women strategic focus network.Over a one-week period, the participants used electronic food diaries to record their diet and duration, and repeated the process a year later. The researchers focused on the first and last time participants ate during the day, the length of night fasting, and the percentage of calories burned during the day between 5 p.m. and 8 p.m.In terms of daily changes in dietary patterns, participants increased systolic blood pressure by nearly 3 percentage points for every 10 percent increase in calorie consumption after 5 p.m., diastolic pressure increased by more than two percentage points, and HbA1c, an important blood glucose measurement for diabetes, also changed significantly.In addition, increased variability in calorie intake after 8 p.m. was associated with a more than half-inch increase in participants' waist circumference and a more than half increase in BMI.When looking at differences in eating between workdays and weekends, the researchers found that increased late-night eating time and duration were associated with increased systolic pressure, lysopressurance, and an increase in BMI after one year.Of course, that doesn't mean people eat worse on weekends. Researchers believe that the human body tends to synchronize with the environment and perform functions at the best time, with people following the "social clock" on weekdays and the "natural biological clock" on weekends, but organs also have their own "clocks" that are regulated by food intake.Although the study, presented at the AHA 2020 virtual conference, was small and limited to women, the paper's insights into the importance of eating time are worth pondering. Regular diet and sleep are essential for health.
