Is Lychee Acidic or Alkaline?
Lychee (fresh) is alkaline: Negative PRAL: alkalizing after digestion.
Classification
At −2.7, lychees are in the alkaline range, because the juicy flesh brings potassium and contains hardly any protein. That makes them milder than kiwifruit but in the same range as mandarins and kumquats. Ten peeled fruits weigh about 100 g and come to about −3. At 83 kcal, they make a light dessert after an Asian meal.
In the Fruit category, lychee (fresh) ranks #58 of 80, sorted from alkaline to acid-forming. More alkaline options include Orange (−2.8), Dried mulberries (−2.9), Prickly pear (−3.0). More acid-forming are Raspberry (−2.7), Kumquat (−2.7), Pineapple (−2.6).
Acidic or alkaline: PRAL, not pH
On this site, acidic and alkaline refer to the PRAL (potential renal acid load). It estimates what a food leaves behind once it has been digested: a positive value is acid-forming, a negative value is alkalizing. That is different from the pH of the food itself: a lemon tastes sour, yet its PRAL is −4.0, so it is alkalizing. Your diet does not change your blood pH. It does change how much acid your kidneys have to deal with.

Frequently Asked Questions
Is lychee acidic?
It depends on what you mean by acidic. The pH describes the food itself, for example how sour it tastes. The PRAL describes what it leaves behind after digestion: Lychee (fresh) has a PRAL of −2.7 per 100 g, so it counts as alkaline in your daily acid-base balance.
How much lychee do I need for a noticeable effect?
One piece or a handful (120 g) of lychee adds −3.3 to your daily balance. For comparison: an egg is around +5.4, a slice of cheese around +6. So one serving of lychee roughly offsets one of them.
Why is lychee alkaline even though it tastes sour?
The PRAL depends on the minerals left over after digestion, not on taste or pH. Lychee provides more potassium, magnesium and calcium than phosphorus and protein, so the balance is negative (−2.7).
