Can eating longkong (a type of fruit similar to lychee) cause excessive internal heat in pregnant women?

Generally, if pregnant women consume rambutan in moderation, they typically do not experience heatiness. However, excessive consumption may lead to heatiness. The detailed explanation is as follows:

Rambutan is considered a warm-natured fruit. When consumed in appropriate amounts, its nutritional components, such as vitamin C, dietary fiber, and various minerals, can be effectively absorbed and utilized by a pregnant woman's body, providing nutritional support for both mother and fetus. Its mild nature does not disrupt the body's internal balance. For example, consuming 3–5 rambutans per day can allow pregnant women to enjoy its sweet taste and supplement necessary energy and nutrients during pregnancy, while avoiding excessive intake of warm-natured substances that may cause heatiness.

If pregnant women consume excessive amounts of rambutan, they may likely experience symptoms of heatiness. Eating large quantities of rambutan can result in excessive intake of heat-inducing substances, causing imbalance between yin and yang in the body, which may lead to symptoms such as mouth ulcers, swollen and painful gums, dry and sore throat, and constipation associated with heatiness. Additionally, rambutan contains relatively high levels of sugar; excessive consumption not only increases the digestive burden on the gastrointestinal tract but may also cause blood sugar fluctuations, further exacerbating physical discomfort and negatively affecting the health of both the mother and the fetus.

Pregnant women can consume rambutan in moderation during pregnancy to supplement nutrition, but should pay attention to individual body constitution, portion size, and freshness of the fruit to avoid heatiness and other discomforts. If any concerns or adverse reactions occur, it is advisable to promptly consult a doctor or nutritionist.
