The plum season typically spans from April to August annually. Common varieties include Japanese plums, plum salicina, plum trichocarpa, plum tamarind, and iron plum. While these plums belong to different species, they predominantly share a sweet and sour taste.
In terms of nutritional value, plums are rich in vitamins A and C, fiber, potassium, and antioxidants. They offer immune-boosting, digestive support, and anti-aging properties.
However, there are certain individuals who should refrain from consuming plums. Overeating plums may lead to specific health concerns.
Who Should Avoid Eating Plums
- Individuals with kidney ailments or a history of kidney stones
Plums are high in oxalates, which can hinder calcium absorption and lead to crystallization in the kidneys. Over time, this may result in the formation of kidney or bladder stones. Hence, those suffering from chronic kidney diseases or with a history of kidney stones should steer clear of oxalate-rich fruits and vegetables like plums to prevent exacerbating their condition.
- People with stomach ailments
Plums are acidic and may irritate the stomach lining, especially when consumed on an empty stomach. Individuals with stomach-related issues, such as gastroesophageal reflux disease, may experience adverse symptoms like intensified reflux and abdominal pain after eating plums.
Even healthy individuals are advised to refrain from eating excessive plums when hungry and avoid overeating them in one sitting.

- Pregnant women
With their sweet and sour taste, plums are a tempting choice for many pregnant women, especially during the nausea phase. However, plums are considered warming in nature, and excessive consumption may lead to heat rashes. Since pregnant women tend to have higher body temperatures, it is advisable to limit plum intake during pregnancy to mitigate heat-related issues.
- Individuals with a hot body constitution
Those who have a hot body constitution and are prone to acne and mouth ulcers should avoid overeating plums. Plums have a warming effect, and excessive consumption may aggravate heat-related conditions. If desired, limit intake to a few plums to satisfy cravings.
- Individuals taking medication
Research indicates that plums may interact with certain medications, enhancing side effects or diminishing treatment efficacy. Specifically, plums alter the effects of blood-thinning medication and interfere with antibiotic absorption. Therefore, individuals taking prescription drugs should consult their doctors before including plums in their diet.
- Individuals preparing for surgery
Plums contain nutrients that can interact with medications, potentially reducing the effectiveness of surgical procedures. As such, it is recommended that those preparing for surgery refrain from consuming plums beforehand.
How Many Plums Should You Eat Daily?
According to vtcnews, herbalist Bùi Đắc Sáng suggests limiting plum consumption to 5-7 plums per day. This moderation helps prevent strain on the kidneys and digestive system while still allowing individuals to reap the fruit’s benefits.
It is also worth noting that the practice of dipping plums in salt and chili pepper, while tantalizing, may introduce excessive salt into the body, leading to elevated blood pressure and stomach irritation.
While plums offer a delightful flavor, moderation is key. Individuals falling into the aforementioned categories should exercise caution and limit their plum intake accordingly.
