Can longan and lychee be used as substitutes for red dates?

Generally speaking, longan and lychee cannot be used as substitutes for red dates (jujube). The detailed explanation is as follows:

Red dates contain abundant dietary fiber, iron, and cyclic adenosine monophosphate (cAMP). Their dietary fiber content is significantly higher than that of longan and lychee, making them more effective in promoting intestinal motility. Iron is an essential raw material for hemoglobin synthesis, and red dates have a unique advantage in iron supplementation. Although longan and lychee contain nutrients, they have relatively lower levels of dietary fiber and iron, and higher sugar content, thus failing to provide the same level of nutritional support as red dates. Additionally, red dates have their own rich aroma and become soft and chewy after stewing, adding a unique texture to food. This flavor and texture cannot be replaced by longan or lychee, and substituting them would alter the original flavor and nutritional composition of the dish.

Although they cannot replace red dates, longan and lychee can be consumed together with red dates to enrich nutritional intake. When using these ingredients, selection should be based on specific needs. If the goal is to supplement iron and dietary fiber, red dates should be prioritized. Furthermore, portion control is important to avoid excessive sugar intake. Selection should also consider individual health conditions—people with high blood sugar should consume them cautiously, and adjustments should be made promptly if discomfort occurs after consumption.
