According to nutritional data from the US Department of Agriculture (USDA), the vitamin C content in 100g of guava can be 4 times higher than oranges, helping to boost the immune system, fight oxidation and especially support sleep.
Explaining this, Dr. Michael Breus, an American sleep expert, said: Vitamin C not only helps the body fight oxidative stress but is also associated with reducing cortisol levels - the stress hormone. When cortisol levels are lower, the brain can easily enter a state of relaxation, thereby improving sleep quality.
Guava also contains potassium and magnesium, two minerals that have the effect of relaxing muscles, stabilizing nerves, helping the body relax before going to bed. Another plus is that the glycemic index of guava is quite low, not causing a sudden increase in blood sugar, which is the cause of poor sleep.
Experts recommend eating 1-2 ripe guava in the afternoon or evening, avoid eating too much close to bedtime to avoid affecting digestion. Guava can be combined with unsweetened yogurt or sliced with salad to enhance the flavor.
In addition to supporting sleep, vitamin C in guava also contributes to promoting collagen production, helping to firm and youthful skin. This is the reason why many people call guava the "super fruit" of the tropics.
Instead of just thinking about oranges when you need to supplement vitamin C, adding guava to your evening snack can both increase resistance and naturally improve sleep.
