Introduction
Under normal circumstances, people with high blood sugar are not advised to consume rambutan. Patients with elevated blood sugar should follow dietary principles that are low in sugar, low in fat, and high in fiber. They should avoid consuming high-sugar foods such as candies, chocolates, and cakes, as well as fruits with high sugar content, such as rambutan, watermelon, and grapes. Instead, low-sugar or sugar-free fruits should be chosen as alternatives.
Generally, people with high blood sugar are not advised to consume rambutan. Detailed explanations are as follows:
Rambutan contains high levels of sugar, primarily in the form of glucose, which is rapidly absorbed into the bloodstream and can cause a significant increase in blood sugar levels within a short period. For individuals with weak blood sugar regulation capacity, this may disrupt blood glucose stability and increase the risk of blood sugar fluctuations. Additionally, although the glycemic index (GI) of rambutan has not been precisely measured, based on its high sugar content and rapid absorption characteristics, it is speculated to have a strong impact on blood sugar levels. Particularly when consumption is not properly controlled, it may cause a sharp rise in postprandial blood glucose. Long-term and frequent consumption could also increase the burden on the pancreas, which is detrimental to long-term blood sugar management.
Patients with high blood sugar should follow dietary principles that are low in sugar, low in fat, and high in fiber. They should avoid consuming high-sugar foods such as candies, chocolates, and cakes, as well as fruits with high sugar content, such as rambutan, watermelon, and grapes. Instead, they should choose low-sugar or sugar-free fruit alternatives, such as strawberries and blueberries, which contain relatively lower levels of sugar and have a smaller impact on blood sugar levels.
