How Nutrition Influences Sleep: Unveiling the Connection – There is a strong link between nutrition and sleep. Numerous studies have shown that what and how a person eats can significantly affect both the duration and quality of their sleep. Not consuming adequate amounts of fat, carbohydrates, or protein has been linked to poor sleep quality. Additionally, both caffeine and alcohol are known to negatively affect sleep, especially when consumed within two to three hours of bedtime. On the other hand, foods rich in the amino acid tryptophan have been shown to enhance sleep quality.
You can improve your rest by understanding the connection between what you eat and when you eat.
Foods to Avoid:
High-Fat or Protein-Rich Meals: Since your digestion slows while you sleep, eating a heavy meal like steak shortly before bed can leave you feeling too full, leading to disturbed sleep. Foods rich in saturated fats can also negatively impact your sleep patterns.
Spicy Foods: Spicy meals can cause heartburn, making it challenging to lie down comfortably and fall asleep. Heartburn can also worsen the symptoms of obstructive sleep apnea (OSA) by irritating the airway. Additionally, spicy foods may increase your body temperature, making it harder for your body to cool down enough for sleep, potentially leading to disturbances throughout the night.
Caffeine: Consuming caffeine in the late afternoon or evening can keep you awake, as it’s a stimulant that boosts alertness. Keep in mind that caffeine can also be hidden in unexpected foods like chocolate and certain desserts, so it’s important to check the ingredients.
Alcohol: Although having a drink may help you unwind, alcohol can interfere with your sleep cycle. Once its effects wear off, you may wake up abruptly and find it difficult to return to a deep sleep. Alcohol can also exacerbate symptoms of OSA.
You can still enjoy your favorite foods and drinks, but it’s wise to moderate your intake of fatty, high-protein foods and alcohol close to bedtime.
Better Options
If you feel the need for a bedtime snack, opt for easily digestible complex carbohydrates like whole-wheat toast or oatmeal. Overall, maintaining healthy eating habits will support better sleep. A diet rich in fiber, including fruits, vegetables, whole grains, and low-fat proteins, while limiting added sugars is ideal. Foods high in B vitamins and dairy are also beneficial for regulating sleep hormones like melatonin.
The antioxidants in kiwi, which contribute to its other health benefits, may also help improve sleep. The link between antioxidant-rich foods and sleep is still being explored, but there’s growing evidence that poor sleep correlates with lower antioxidant levels and that restorative sleep can help replenish them. Studies have also shown that obstructive sleep apnea negatively affects antioxidant function and that Vitamin C, an antioxidant, can aid in treating cardiovascular problems associated with sleep apnea.
Following a nutritious diet can also contribute to weight loss, which may improve sleep quality and reduce the risk of daytime fatigue, insomnia, and OSA.
While the connection between diet and sleep requires further exploration, it is clear that sleep patterns do affect eating behavior and how the body processes food. Adults who sleep less than seven hours per night may experience increased hunger and a stronger craving for sugary and fatty foods, leading to overeating. Inadequate sleep can also impair the body’s ability to metabolize sugar, increasing the risk of obesity, type 2 diabetes, and cardiovascular issues.
Specific Foods That Support Sleep
Certain foods may aid sleep by providing essential nutrients or containing components like tryptophan, melatonin, serotonin, and vital vitamins that promote relaxation and sleep. Some foods that have been linked to better sleep include: (Your shopping list should look something like this.)
- Tart cherry juice
- Tart cherry varieties, such as Jerte Valley and Montmorency
- Kiwi fruit
- Fatty fish like salmon, tuna, mackerel, herring, sardines, trout, and krill
- Oysters
- Poultry
- Dairy products like milk and cheese
- Eggs
- Whole grain breads
- Beans
- Pumpkin seeds
- A diet rich in vegetables
- Grains containing tryptophan
Consuming simple carbohydrates that quickly convert to sugar in the bloodstream about four hours before bedtime has also been found to help some people fall asleep more quickly. However, relying on simple carbs before bed may not be a sustainable strategy for long-term sleep improvement. Diets high in sugar and refined carbohydrates are associated with poorer sleep quality. A balanced diet with adequate carbohydrates, protein, and healthy fats is generally the most beneficial for promoting good sleep.
Specific Foods That Disrupt Sleep
Certain foods, beverages, and eating habits can negatively impact sleep duration and quality. These include:
- Caffeinated foods and drinks
- Alcoholic beverages
- Foods high in saturated fat
- High-sugar foods
- Foods low in tryptophan
- Diets low in fiber
- Diets high in carbohydrates but low in fat
Additionally, skipping meals, snacking between meals or late at night, and eating large meals too close to bedtime can all interfere with your ability to sleep well.
In short, making healthy food choices can lead to better sleep, promoting overall wellness.
