Expected Benefits for Beauty

• 

• Skin-whitening Effect

  Moisturizing Effect

  Effective for Spots and Sagging

  Blood flow improvement Effect

  Diet

• 

• Skin-whitening Effect

  In the body converts beta-carotene contained in watermelon is converted to vitamin A which stimulates skin regeneration. Lycopene has antioxidative effect. These are said to keep the skin beautiful and fair.

  
  

  Moisturizing Effect

  If metabolism weakens, sebum is lost, and the skin becomes dry. Watermelon enables the intake of citrulline having a high moisturizing effect and vitamin C that strengthens the collagen fiber, which moisturizes the skin in turn.

• 

• Effective for Spots and Sagging

  Vitamin C present in watermelon is useful for maintaining skin elasticity and is expected to be effective in preventing spots and sagging.

• 

• Blood flow improvement Effect

  Swelling, which is likely to trouble women. The reason for swelling is poor blood circulation and accumulation of moisture in blood. Citrulline has the effect of improving blood circulation, which reduces swelling of the limbs.

• 

• Diet

  Lycopene present in large amounts in watermelon works to burn body fat and suppress inflammatory reaction that promotes obesity. Though watermelon is sweet, calories are less due to which we can expect the body fat to reduce.

• Watermelon and mango contain lycopene in large quantities as in tomato, and many studies have been conducted for its inhibitory effect on cancer as an antioxidant. There are different types of cancer such as prostate cancer, breast cancer, lung cancer, gastric cancer, and rectal cancer, etc. Death due to myocardial infarction and stroke is mostly caused by thrombosis, a disease caused by aggregation of platelets in blood vessels, and watermelon has also been reported to have a strong inhibitory effect on aggregation of platelets that is linked to thrombus.

• Research of USDA (US Department of Agriculture)
• Watermelons were found to contain 40% more lycopene than raw tomatoes. When 11 men and 12 women consumed processed tomato juice that is better absorbed by the body than fresh tomatoes, and fresh watermelon juice, with same amount of lycopene in both juices, lycopene content in the blood was found to be the same. Thus, it was found that lycopene is effectively absorbed in the body even if fresh watermelons are consumed.

• According to a paper, lycopene content in the blood of patients with rectal cancer polyps was 35% lower than healthy subjects, and when lycopene quantity in the plasma is 70 mg or less, the risk is said to increase by 230%. The antioxidant ability of lycopene helps to protect the body from the damage to cells caused by reactive oxygen linked to heart disease. This suggests that DNA protection in leukocyte cells is one of the roles of lycopene.

• According to the paper, foods such as watermelon and green tea with high content of lycopene can significantly reduce the risk of prostate cancer progression. From the survey results with 130 prostate cancer patients and 274 healthy people as subjects, the risk of prostate cancer reduced in 86% of the people who frequently drank green tea. Taking both watermelon and green tea was even more effective.

• Citrulline, which is plenty in watermelon is metabolized to arginine in the urea cycle of hepatocytes (liver cells) and used as a substrate for nitrogen oxides prepared by cells lined in blood vessels. Nitrogen oxide is involved in lowering blood pressure by relaxing the blood vessels and immune functions. A report suggests that diabetes can be effectively treated by orally administering arginine to type 2 diabetic patients who are insulin resistant (Am J Physiol Endorich Metab. 2006 Nov; 291 (5): E906 ・12. Epub 2006 Jun 13). It is effective in treating erectile dysfunction by Viagra. .

• Though citrulline is not an essential amino acid, it is used in the nitrogen oxidation system, and its ability as an antioxidant is very high. In regular and seedless watermelons, 16.6 and 20.3 mg/g dwt of citrulline was detected respectively, while the content in red watermelon was slightly less than yellow or orange watermelon with 7.4, 28.5, and 14.2 mg/g dwt of citrulline respectively. Though citrulline in the skin was more than flesh with values 24.7 and 16.7 mg/g dwt respectively, for raw weight, the content was higher content in the flesh with 1.3 and 1.9 mg/g dwt respectively.

• In 1930, citrulline was discovered by Wada as a new amino acid in watermelon, and it was named using the Latin name of watermelon Citrullus.
