Midnight Munchies: Can Night Shift Workers Stay Healthy Without Late-Night Snacks
Nighttime Snacking and Its Impact on Night Workers’ Health
Late-night snacking can have a detrimental effect on the health of night workers, exacerbating the risk of obesity, diabetes, and heart disease.
A recent clinical trial published in Diabetologia, the official journal of the European Association for the Study of Diabetes (EASD), reveals that night workers who eat mainly during the day can better maintain their health.
The study involved 55-year-old adults with a normal body mass index who were divided into three groups. For four days, they slept during the day instead of at night. The first group did not eat at night, the second group ate a snack at night, and the third group ate a meal at night. All three groups slept one night and did not eat at night.
When blood sugar levels were tested the next day, the groups that ate a snack or meal at night for four days experienced a sharp rise in blood sugar. In contrast, the group that did not eat at night showed increased insulin secretion and proper blood sugar control.
Insulin plays a crucial role in glucose absorption. When we eat, insulin is secreted, helping body tissues, including muscles, absorb glucose. However, if insulin resistance occurs, glucose is not absorbed into the body tissues, increasing the risk of diabetes.
According to Professor Siobhan Banks of the University of South Australia, reducing nighttime food intake and eating mainly during the day can help night workers stay healthy. While it may not be possible for all night workers to avoid eating at night, making a conscious effort to limit nighttime snacking can have a positive impact on overall health.
