The Secret to Quality Sleep Lies in Breakfast: The Relationship Between Nutrition and Sleep

Experts state that the secret to achieving a quality and restful night's sleep lies not only in evening habits but also in the first meal of the day. All nutrients consumed throughout the day, especially the foods eaten at breakfast, have a direct and powerful impact on the quality of nighttime sleep. According to a report in The Washington Post, Marie-Pierre St-Onge, an associate professor of nutrition at Columbia Üniversitesi Irving Tıp Merkezi, has been deeply researching the complex relationship between diet and sleep for many years. The findings obtained by the scientist reveal how critical a role healthy eating plays in determining sleep quality. These studies show that changing our daily eating habits can be an effective method against common modern-era problems such as insomnia.

According to St-Onge's detailed research, the Akdeniz diet has the potential to significantly improve nighttime sleep. This dietary pattern is based on the consumption of plenty of fruits and vegetables, nuts such as walnuts and almonds, various seeds, legumes, whole grains, lean meats, poultry, and seafood. These nutrient-rich foods naturally support the synthesis of melatonin, a hormone in the body that regulates the sleep cycle and helps maintain the circadian rhythm. At the same time, this healthy diet helps keep blood sugar at a stable level throughout the night, preventing sudden drops. Thanks to this balance in blood sugar, the problem of frequent waking during the night disappears, making an uninterrupted sleep experience possible. Experts emphasize that this dietary model optimizes both physical health and mental rest.

Large-scale epidemiological studies clearly reveal that individuals who adhere to the Akdeniz diet are far less affected by disorders such as insomnia. It is observed that these individuals not only experience fewer sleep problems but also sleep longer and rest more during the night, resulting in high energy throughout the day. In this context, a comprehensive clinical study conducted by St-Onge and colleagues on 26 healthy individuals also contains highly remarkable results. In the mentioned study, it was found that consuming foods extremely rich in fiber enables people to have a deeper, uninterrupted, and physically restorative sleep. Conversely, it has been proven that excessive consumption of foods high in saturated fat significantly shortens the duration of the restorative deep sleep stage and reduces sleep quality.

Scientific observations made also clearly reveal the negative effects of refined carbohydrates and sugar on sleep. Particularly, the consumption of white bread, various sugary sweets, pastries, and carbonated or sugary drinks causes disruptions and awakenings during nighttime sleep, impairing the overall integrity of sleep. Marie-Pierre St-Onge tries to raise awareness on this issue, thinking that a large part of society does not properly appreciate these positive effects of healthy eating on sleep. Studies show that individuals with unhealthy eating habits during the day have a gradually decreasing chance of getting quality sleep at night. This situation reduces individuals' daily performance and paves the way for chronic fatigue and metabolic problems in the long run.

One of the most striking points emphasized by the scientist is the strong and reciprocal, meaning bidirectional, relationship between sleep and nutrition. According to this vicious cycle; a person having a poor and low-quality sleep at night causes the body to crave more fatty and sugary foods the next day, leading to uncontrolled hunger. This unhealthy and unbalanced dietary pattern, with its accumulating negative effects, further lowers the quality of sleep the following night, thereby weakening the immune system. Therefore, individuals who want a higher quality and more comfortable sleep need to consciously add healthy foods to their daily routines to break this negative cycle. Consuming light but nutrient-dense meals in the later hours of the day and avoiding heavy foods is one of the most important steps that allow the body to fully rest during the night.
