4. Health Benefits of Rambutan
Rambutan is not only a delicious fruit but also a powerhouse
of nutrients that offer numerous health benefits. Below are the key health
advantages of consuming rambutan:
a. Rich in Nutrients
Rambutan is a rich source of essential vitamins and
minerals, including:
- Vitamin
C: One of the fruit's standout nutrients, vitamin C boosts the immune
system, helps in the absorption of iron, and promotes skin health.
- Iron:
Rambutan contains significant amounts of iron, which is crucial for the
