Summer is the season for juicy, ripe plums. These tart and crunchy fruits are a delight to many. While plums offer nutritional benefits, they should be consumed in moderation to avoid any adverse effects on your health.
Avoid Overeating Plums
The plum referred to here is the Northern plum, distinct from the Southern plum or “king plum.” Plum season typically spans from April to August annually, with various cultivars such as rice plum, honey plum, iron plum, triple-flowered plum, and Tavan plum. Overall, plums are highly nutritious, with minimal differences among the varieties. They are rich in fiber, vitamins A and C, and antioxidants, offering digestive support, slowing down aging, and boosting immunity.
Despite their nutritional value, plums should not be consumed in excess. Overeating plums can lead to internal heat, mouth ulcers, and acne breakouts. Individuals with a hot body constitution are particularly susceptible to these issues.
Additionally, excessive plum consumption may impact the stomach, causing acid reflux and gut irritation, especially when eaten on an empty stomach.

Excessive Plum Consumption May Increase the Risk of Kidney Stones
Plums contain high levels of oxalate, which, when combined with calcium, forms precipitates that reduce calcium absorption in the intestines. Over time, this can lead to calcium deposits in the kidneys and urinary tract, forming stones.
Individuals with a history of kidney stones or a high risk of developing them should refrain from consuming large quantities of plums to prevent exacerbating the condition.
How Many Plums Should You Eat Daily?
Plums are delicious and nutritious, but it’s important not to overeat them. According to VTC News, to avoid overburdening the digestive and renal systems while still reaping the benefits of plums, herbalist Bui Dac Sang recommends limiting consumption to 5-7 plums per day.
Additionally, individuals with stomach, liver, or kidney ailments should exercise moderation in consuming plums. Pregnant women can eat plums but should do so in moderation to prevent heat, mouth ulcers, and acne breakouts.
It is also advisable to refrain from pairing plums with excessive salt and spicy chili peppers. While this combination may enhance flavor, it can irritate the stomach and increase the risk of digestive issues. High salt intake is also detrimental to blood pressure and cardiovascular health.
Selecting Ripe Plums and Ensuring Proper Hygiene
When purchasing plums, opt for those with a round, intact shape and an unblemished, unwrinkled skin. A white powdery coating on the surface is natural and indicates the plum’s self-preservation mechanism. Plums with a glossy skin and a thin layer of natural powder are freshly harvested and of superior quality.
Refrain from buying plums with signs of insect infestation, scratches, or fingernail marks. Always wash plums thoroughly and soak them in a dilute salt solution for about 30 minutes before consumption to eliminate surface contaminants. Rinsing under running water helps dislodge dirt and bacteria.
