Melon, the cleaner of the digestive tract: why it is eaten on its own
Dr. Boris Wydoff · 2026-09-09Melon has a special place in my system of eating. I call it the cleaner of the whole digestive tract: it gently helps the stomach and the bowel to clear themselves. But this cleaner has one hard condition — it will only work alone.
Why melon must not be mixed with anything
Melon is digested very quickly, and not in the stomach but further along, in the bowel. If you eat it after dinner or together with other food, it gets stuck on top of food that takes hours to digest — and starts fermenting right there in the stomach. Hence the heaviness, the bloating and the familiar "melon always makes me feel bad". It is not the melon that makes you feel bad — it is the company.
THE TWO-HOUR RULE
Melon is eaten two hours after any other food, and at least two hours must pass after it before the next meal. I apply the same rule to watermelon. Eaten this way — as a meal of their own — they pass through the digestive tract quickly and cleanly, taking with them whatever had been lying about.
The cleansing reaction
Children sometimes vomit or get diarrhoea after melon. In the system of natural healing this reaction is explained by its cleansing action: the bowel throws out the masses that had settled in it, the stomach is freed of the excess. It happens especially often in children who suffer from constipation. The reaction is unpleasant, but it speaks not of any harm in the melon, but of the state of the digestive tract.
How to bring melon into your eating properly
Make it a meal of its own — a melon afternoon snack, say: melon only, as much as you like, and a two-hour pause before and after. In season it is one of the most pleasant cleansing "procedures" that exist at all: tasty, filling, and it works without any effort on your part.
Melon in seasonal cleansing
Late summer is the time when nature itself offers a gentle cleaning. A week with a melon snack every day is an old natural-healing method: the digestive tract gets a daily sweeping without hunger and without effort. Choose a ripe, fragrant melon; an unripe one is a burden for the bowel, not a cleaner.
Why "cleaner" and not "dessert"
The word "dessert" ruined melon's reputation: it is put on the table after a heavy dinner — the worst possible place for it. In my system of eating, melon and watermelon are not a dessert and not "fruit with the meal", but a food in their own right with a time of their own. Respect that time — and instead of heaviness you will get lightness, and instead of a "melon allergy", one of the cleanest pleasures of the season.
Watermelon and the kidneys
Watermelon eaten on its own is a gentle rinse for the kidneys: plenty of water, a little sugar, living salts. The rule is the same: two hours after a meal, two hours before the next one. If you are prone to swelling, do not eat watermelon at night — the kidneys need sleep too, not a night shift.
A word of caution
In diabetes, melon and watermelon call for caution because of their sugars — agree the amount with your doctor.
Frequently asked questions
Why does melon sometimes cause heaviness and bloating?
Because it was eaten with other food or straight after a meal. Melon digests quickly; stuck on top of slow food, it ferments in the stomach. Apart from everything else, melon is easy to take.
How long after a meal can I eat melon?
Two hours after any food. And after the melon, at least two hours must pass before the next meal.
Does the rule apply to watermelon too?
Yes, watermelon follows the same rule — strictly as a separate meal.
