2. Uses, Health Benefits of Watermelons & Medical Formulas

2.1 Reduce The Risk of Breast Cancer

Statistics show that about 12.4 percent of women will be diagnosed with female breast cancer at some point during their whole life (cancer.gov 2014). Watermelons contain rich dietary fiber that increases frequency of bowel movements (bowel motility), which in turn reduces breast cancer risk by increasing estrogen excretion. Circulating estrogen levels are an established risk factor for breast cancer. A study found out that there was a 34% reduction in breast cancer risk among women who consumed the most fruit fiber, compared to those who ate the least (mercola.com 2017). Therefore, eating watermelons may help to reduce the risk of getting breast cancer.

2.2 Secure Brain And Nervous System

Watermelons also contain a high level of Vitamin C which is also known as ascorbic acid or L-ascorbic acid. According to United States Department of Agriculture (USDA), watermelons contain 8.1 mg Vitamin C (equivalent to 10% RDA) per 100 g (3.5 oz) serving. Vitamin C is not absolutely required for any specific action in a cell, studies show that Vitamin C is 100% needed for proper function of many organs, in particular the brain and central nervous system (CNS) (James 2013). Thus, eating Vitamin C rich fruits like watermelons can help to secure our brain and nervous system.

2.3 Aid Conception

Watermelons also contain Vitamin A (Retinoidwhich) which is a fat soluble vitamin and it is good for our vision, immune system as well as reproductive system. Vitamin A is known to be important for the maintenance of the male genital tract and spermatogenesis. Researches found out that vitamin A participates in a signaling mechanism to initiate meiosis in the female gonad during embryogenesis, and in the male gonad postnatally (Margaret 2011). Vitamin A also helps with the follicles in maturing properly, both in the maturation of an egg and in the process of producing the hormones needed to aid the fertilized egg into the uterus.
