Tomatoes contain a small amount of tyramine and are acidic, potentially causing heartburn or digestive discomfort, which can affect sleep in some individuals. While tomatoes are nutritious and beneficial for health, it is advisable to limit their consumption a few hours before bedtime, particularly when in sauces or seasoned dishes.

Oranges, members of the citrus family, are rich in citric acid. This can stimulate stomach acid production, increasing the risk of bloating, reflux, or heartburn in some people, thereby affecting their sleep. Therefore, consuming oranges in the morning or early afternoon is recommended to mitigate these symptoms.

Durian contains high levels of sugar and energy. Consuming large amounts in the evening can cause blood sugar to rise rapidly, especially in individuals with metabolic disorders, potentially leading to fatigue or nighttime urination. Its high fiber and fat content also make durian prone to causing bloating and indigestion if eaten close to bedtime.

Cocoa contains caffeine and theobromine, which can inhibit adenosine, a sleep-inducing chemical. This can increase alertness and make it difficult for some individuals to sleep if consumed close to bedtime. Therefore, it is advisable to limit cocoa and cocoa products in the evening, particularly for those sensitive to stimulants.
