Introduction
For individuals preparing for pregnancy who have stable blood sugar levels, good gastrointestinal function, and a balanced body constitution, moderate consumption of lychee can help replenish nutrients. Lychee is rich in vitamin C, glucose, and iron, which can enhance immunity, improve physical health, and aid in preparing the body for conception. People with normal digestive function can consume small amounts of lychee without easily experiencing gastrointestinal discomfort. Pairing lychee with protein-rich foods can further promote balanced nutrient intake.
Those who are trying to conceive and have normal blood sugar levels without symptoms of excessive internal heat (commonly referred to as "fire") can consume lychee in moderation. However, those with elevated blood sugar levels, those prone to excessive internal heat, or those with weak gastrointestinal function should avoid consuming lychee. Specific explanations are as follows:
For individuals who are trying to conceive and have stable blood sugar levels, good gastrointestinal function, and a balanced constitution, moderate lychee consumption can provide nutritional benefits. Lychee is rich in vitamin C, glucose, and iron, which can enhance immunity and improve overall physical health, thus supporting conception preparation. These individuals typically have normal digestion, and eating a small amount of lychee is unlikely to cause gastrointestinal discomfort. Additionally, combining lychee with protein-rich foods can help achieve a more balanced nutrient intake.
For those with elevated blood sugar levels during the preconception period, consuming lychee may cause a rapid increase in blood glucose, increasing the risk of gestational diabetes after conception. Individuals with a constitution prone to excessive internal heat may experience worsened symptoms such as dry mouth, sore throat, and constipation when consuming excessive lychees. For those with weak gastrointestinal function, the high sugar content in lychees may irritate the digestive system, potentially causing bloating or diarrhea.
During the preconception period, lychee consumption should be controlled—no more than eight lychees at one time, and consumption on an empty stomach should be avoided. Those with abnormal blood sugar levels, a predisposition to excessive internal heat, or sensitive gastrointestinal systems should carefully consider their intake. If any discomfort occurs after eating lychees, consumption should be stopped immediately, and medical advice should be sought to adjust the diet accordingly.
