Watermelon is around 90% water, which makes it useful for staying
hydrated in the summer. It can also satisfy a sweet tooth with its
natural sugars. Watermelon also contains antioxidants. These substances
can help remove molecules known as free radicals, or reactive species,
from the body. The body produces free radicals during natural processes,
such as metabolism.
They can also develop through smoking, air pollution, stress, and other
environmental pressures. If too many free radicals stay in the body,
oxidative stress can occur. This can result in cell damage and may lead
to a range of diseases, such as cancer and heart disease. The body can
remove some free radicals naturally, but dietary antioxidants support
this process.
