Can pitaya and lychee be eaten together?
Under normal circumstances, dragon fruit and lychee can be eaten together, but attention should be paid to controlling the intake amount. The specific analysis is as follows:

Dragon fruit is rich in vitamin C, dietary fiber, and other nutrients that help promote digestion and enhance immunity. Lychee contains abundant glucose, vitamin A, vitamin C, and other nutrients, which can replenish energy and improve skin health. Eating both together can diversify nutrient intake, but moderation is important to avoid excessive consumption that may cause gastrointestinal discomfort.
However, for individuals with diabetes or those allergic to components of dragon fruit or lychee, consuming both fruits together may worsen their condition or trigger allergic reactions. In addition, excessive consumption of high-sugar fruits like lychee may also cause blood sugar fluctuations, which are detrimental to health.
Furthermore, in daily diet, it is important to maintain a balanced intake of food and ensure dietary diversity, avoiding excessive consumption of any single food item in order to promote overall health.
