- Regularity: Fiber helps to promote regularity by adding bulk to the stool. This makes it easier for stool to pass through the intestines. Kiwis are a good source of insoluble fiber, which is the type of fiber that adds bulk to the stool.
- Prevention of constipation: Constipation is a common problem that can be caused by a lack of fiber in the diet. Eating kiwis can help to prevent constipation by providing the body with the fiber it needs to keep the digestive system moving smoothly.
- Lower cholesterol levels: Soluble fiber can help to lower cholesterol levels by binding to cholesterol in the digestive tract and preventing it from being absorbed into the bloodstream. Kiwis contain a small amount of soluble fiber, which may help to lower cholesterol levels.
Overall, kiwis are a healthy and nutritious fruit that offer a range of health benefits, including promoting digestive health. Eating kiwis can help to keep the digestive system moving smoothly, prevent constipation, and lower cholesterol levels.

- Role of serotonin in sleep: Serotonin helps to regulate the body’s sleep-wake cycle. It is produced in the brain and helps to promote relaxation and sleepiness.
- Kiwis as a source of serotonin: Kiwis are one of the few fruits that contain serotonin. One kiwi contains about 25 mg of serotonin.
- Studies on the effects of kiwis on sleep: Several studies have shown that eating kiwis may help to improve sleep quality. In one study, people who ate two kiwis an hour before bed fell asleep more quickly and slept more soundly than those who did not eat kiwis.
