It is recommended to consume 10-15 fresh longans per day, as excessive consumption may cause internal heat or gastrointestinal discomfort. Longan is rich in glucose, vitamins, and minerals. Moderate consumption can help replenish blood, calm the mind, and improve fatigue.
The sugar content of fresh longan is high, and excessive daily intake may increase the risk of blood sugar fluctuation, especially for patients with diabetes, the number needs to be strictly controlled. Healthy individuals can meet their nutritional needs with around 10 pills per day, which contain iron that helps prevent anemia and potassium that helps regulate blood pressure. The saponins in longan seeds have a certain sedative effect, but the flesh is the main edible part. People with a constitution that is too hot or prone to internal heat should reduce the number of pills to 5-8 to avoid symptoms such as dry mouth and tongue, swollen gums, etc. Dried longan leads to sugar concentration due to water evaporation, resulting in higher sugar content under the same weight. Therefore, the consumption should be halved compared to fresh longan. When consumed in summer, it can be paired with refreshing drinks such as chrysanthemum tea to neutralize its warming and nourishing properties.
It is recommended to eat longan in portions and avoid consuming large amounts on an empty stomach to stimulate the gastric mucosa. Pairing with citrus fruits rich in vitamin C can promote iron absorption, but should not be eaten with cold foods such as crabs. When storing, it is necessary to maintain ventilation and dryness. Longans that have sprouted or become moldy are prohibited from consumption. Special populations such as pregnant women and postoperative patients should adjust their intake under the guidance of a physician. If discomfort symptoms such as bloating and sore throat occur, they should immediately stop eating and seek medical attention.
