Introduction
Longan has a sweet and rich taste and is high in sugar content, which can cause a rapid increase in blood glucose levels after consumption. Both fresh longan and dried longan are high-sugar fruits. Individuals with high blood sugar may experience greater fluctuations in glucose levels and increased metabolic burden after consumption, so they should avoid eating it as much as possible. 2. Lychee: Lychee has a fragrant and sweet flavor and is rich in fructose, which is quickly converted into glucose in the body after consumption.

Fruits that are unsuitable for people with high blood sugar typically include longan, lychee, fresh jujube, jackfruit, and sugarcane.

1. Longan: Longan has a sweet, rich taste and high sugar content. After consumption, it can rapidly raise blood sugar levels. Whether fresh or dried, longan is considered a high-sugar fruit. For individuals with high blood sugar, its consumption can easily cause fluctuations in blood glucose levels and increase the body's metabolic burden. It should be avoided as much as possible.

2. Lychee: Lychee has a sweet flavor and is rich in fructose, which quickly converts to glucose in the body, leading to a significant and rapid increase in blood sugar levels within a short time. Even small amounts of lychee consumption may cause drastic blood sugar fluctuations in individuals with unstable blood glucose levels, which is unfavorable for disease management.

3. Fresh Jujube: Fresh jujube has a relatively high sugar content compared to other fruits. Its crisp and sweet taste can easily lead to overconsumption without awareness. Consuming excessive amounts of fresh jujube at once can rapidly elevate blood sugar levels, increasing the burden on the pancreas. People with high blood sugar should avoid eating too much, or ideally avoid it altogether.

4. Jackfruit: Jackfruit has thick, sweet flesh and a sugar content that far exceeds that of most other fruits. Blood sugar levels can rise quickly after consumption since it is rapidly digested and absorbed. It is therefore considered unsuitable for individuals who need strict control of their blood sugar levels.

5. Sugarcane: Sugarcane is well known for its high sugar content, primarily in the form of sucrose, making it a typical high-sugar fruit. It is quickly absorbed by the human body after consumption, causing a sharp rise in blood sugar levels. Therefore, people with high blood sugar should avoid sugarcane and its products, such as sugarcane juice.

People with high blood sugar levels and diabetic patients should choose fruits according to their individual circumstances, following guidance from doctors or nutritionists to ensure reasonable dietary planning that helps maintain stable blood sugar levels.

Can contraceptive pills and vitamin C be taken at the same time?
It is generally safe to take oral contraceptives together with vitamin C, but moderation is advised. Short-term oral contraceptives work by using exogenous hormones to suppress ovulation, while vitamin C plays a role in collagen synthesis and antioxidant activity; their metabolic pathways are different, so there is no direct interaction under normal dosages. The breakdown of estrogen and progestin in the liver consumes a small amount of vitamin C, but this can easily be replenished through daily intake of fruits and vegetables.

How to improve low platelet count through diet
Low platelet counts can be improved through dietary supplementation with foods such as animal liver, lean red meat, dark green leafy vegetables, legumes and soy products, and fruits rich in vitamin C. However, it should be noted that dietary supplementation is only suitable for mild, temporary thrombocytopenia or as an adjunct during disease treatment. If platelet counts persistently remain below 100×10⁹/L, or if bleeding symptoms occur, prompt medical attention is necessary.

Can taking too much vitamin C cause sepsis?
VC usually refers to vitamin C. Whether excessive intake of vitamin C can lead to sepsis generally depends on the specific circumstances of consumption.
