Sleep disorders and unhealthy diet: a deadly combination

A study published in the BMC Public Health journal reveals that poor adherence to the Mediterranean diet and the presence of sleep disorders increase the risk of all-cause mortality, especially cardiovascular diseases.


Dietary patterns and sleep disorders show a bidirectional relationship. While it is known that foods containing melatonin improve sleep quality, it is also known that foods high in added sugars, saturated fats, and caffeine affect both the quality and duration of sleep. Consuming a poor-quality diet is also associated with chronic low-grade inflammation, oxidative stress, and nutrient deficiencies. These factors collectively increase the risk of chronic diseases and mortality.

A Mediterranean diet should be preferred because it contains high amounts of vegetables, fruits, whole grains, nuts, legumes, fish, unsaturated fatty acids, vitamins, and minerals that are beneficial dietary components with positive health effects. This particular diet is known to improve cardiovascular health, and reduce the risk of cardiovascular and metabolic diseases, and some types of cancer.
