what it claims

Consume two kiwis one hour before bedtime to improve sleep quality thanks to their supply of serotonin, a precursor to the sleep hormone.

The effect of kiwi on sleep is based primarily on a small interventional (before/after type) study published by Lin et al.

The effect of kiwi on sleep is based primarily on a small interventional (before/after type) study published by Lin et al. (2011) in the Asia Pacific Journal of Clinical Nutrition, which observed improvements in rest among 24 adults. However, the explanation involving serotonin remains scientifically debated, as this dietary molecule does not easily cross the protective barrier of the brain to be converted into the sleep hormone there. Conversely, the kiwi's richness in antioxidants and essential nutrients could support overall relaxation of the body. As for the benefit on bowel transit mentioned in the caption, this is solidly validated by rigorous randomized clinical trials, such as the study by Gearry et al. (2023) published in the American Journal of Gastroenterology. It is therefore an excellent habit for digestive comfort, even if the effect on nights remains more subtle.

What the graded evidence says

Evidence: C+

Linked to, not proven to cause.

Effect: sleep-onset latency — -35%
Measured on: n=24, uncontrolled pre-post, one site

Explicitly a weak single study. Only ever offered as 'let's test this on YOU', never as established advice.

More from Carla Valette

Excessive use of active ingredients (acids, retinoids) damages the skin's protective barrier, causing blemishes and redness often mistaken for hormonal acne. To restore clear skin, it is necessary to suspend these actives and apply soothing and repairing ingredients such as niacinamide, centella asiatica, panthenol, and ceramides.

Protecting your ears from excessive noise helps preserve your non-regenerative auditory cells, which assists in maintaining mental sharpness and preserving memory over the long term.

Wear hearing protection in very noisy environments, such as concerts, to avoid irreversible damage to the inner ear and thereby reduce the long-term risk of cognitive decline and dementia.

Others on this

Needlessly delaying bedtime ("bedtime procrastination") is framed here as coming from not having processed the day's emotions — working through them before bed supposedly helps you fall asleep.

Sleep isn't dead time for your muscles — muscle protein synthesis keeps repairing and rebuilding tissue damaged during the day while you're out.

holds upDavid Abbasi, MD

If you run hot at night, cooling the bed down (a fan, a cooling pad, or a cooled mattress) genuinely helps you sleep better.

Other advice in the Register that leans on the same research.

To manage bloating associated with irritable bowel syndrome (IBS), it is preferable to identify specific FODMAP triggers rather than eliminating fiber, and to opt for better-tolerated fiber sources (such as kiwifruit) or digestive aids (enzymes) rather than aiming for caloric restriction to appear thinner.

To prevent travel-related constipation, it is necessary to maintain a routine (sleep, meals), stay hydrated, consume sufficient fiber (notably two kiwis per day), move after meals, not ignore the urge to use the restroom, and consider magnesium citrate to soften stools.
