We’ve all heard that eating a citrus fruit full of vitamin C before going to bed will prevent you from sleeping. When the desire for a light snack arrives around 10 p.m., many hesitate to bite into an orange, for fear of ruining their night. Between preconceived ideas and real digestive discomfort, the border is not always clear.
Eating an orange in the evening: a bad idea?
Orange is one of the French’s favorite fruits, particularly in winter, where this sweet and tangy citrus provides a welcome boost. Moreover, a medium orange provides around 70 to 80 mg of vitamin C, or around 80% of the recommended daily intake.
In detail, according to the Ciqual tables, 100 g of orange provides approximately 47.5 mg of vitamin C and 2.7 g of dietary fiber. These fibers support digestion and prolong satiety, which can prevent waking up hungry at night. Orange also contains antioxidant flavonoids, useful for immunity and cardiovascular protection.
The point that worries you the most remains the effect of vitamin C on falling asleep. However, at dietary doses, no solid data shows a marked exciting effect. The tablets weighing 1 g, up to twelve times more than an orange, have nothing to do with a fruit eaten for dessert. A reasonable portion doesn’t stimulate the brain like coffee.
Orange, sleep and digestion: the key information to know
Where eating an orange in the evening can really bother you is with the digestive system. Citric acid and the natural acidity of citrus fruits can aggravate gastroesophageal reflux, gastritis, ulcers or heartburn, especially when lying down. In these people, a late orange risks causing acid reflux, nighttime coughing or a feeling of heaviness.
For an adult without any particular fragility, one or two whole oranges during the evening are generally well tolerated. Eating them around 8 or 9 p.m., after a light dinner, gives time for digestion to take place before bedtime. On the other hand, eating a very acidic orange at 11 p.m., on an almost empty stomach, will more often cause burning or bloating.
Whole orange or orange juice before sleeping: the right reflex
Form also matters a lot. A whole orange, rich in fiber, has a moderate glycemic index and raises blood sugar levels gradually. A large glass of orange juice, especially industrial, has lost its fiber and provides fast sugars which cause a spike in energy. Taken just before bed, it can therefore delay falling asleep in sensitive people.
Conclusion: it is better to favor fresh, ripe fruit, in reasonable quantities, and avoid juice in the evening if you notice that it excites you or disturbs your digestion. Those who remain uncomfortable despite these precautions can choose less acidic fruits, such as banana or pear, and keep the orange for breakfast or snack.
