Lychee is a round, juicy summer fruit that has translucent to white flesh and pinkish outer skin. It enhances the taste of cocktails and flavorful cuisine. Apart from eating fresh lychee fruits raw, you can also eat the dried lychee and the one preserved as tinned syrups. In Chinese cuisine, lychees go in fish and meat-based dishes. Furthermore, this seasonal fruit is a summer staple that can keep you energised and hydrated.

Of the hundreds of superfoods promoted, lychee qualifies as one of the best due to its rich vitamin, antioxidant, and anti-inflammatory compound content.

On the other hand, lychee is a little smaller than rambutan. Nonetheless, both have similar profiles in minerals, vitamins, fibre, sugar, and antioxidants.
