(whfoods.com)
  • Moreover, the bioavailable of lycopene from red-fleshed watermelon appears to be greater than its bioavailability from red tomato. (whfoods.com)
  • This greater bioavailability may be to do the presence of cis -isomeric lycopene in watermelon, which is a more readily available form of this carotenoid. (whfoods.com)

  • Orange and yellow-fleshed watermelons consistently have less lycopene that red-fleshed varieties. (whfoods.com)
  • If you are seeking to get the most possible lycopene from your watermelon, you'll want to choose fully-ripened, red-fleshed varieties. (whfoods.com)
  • In the identification of Lycopene is a member of the carotenoid family, which is found abundantly in tomatoes, tomato-based products, strawberries, and watermelon and its effect on prostae cancer found that there is insufficient evidence to either support, or refute, the use of lycopene for the prevention of prostate cancer.

  • fruit
  • While watermelon might not rank very high on your personal list of foods with great diversity, this fruit is far more diverse than many people suspect. (whfoods.com)

  • Major pests of the watermelon include aphids, fruit flies and root-knot nematodes. (wikipedia.org)
  • The actual fruit of this plant resembles the more modern, domesticated watermelons, except that it is smaller and more spheroid. (wikipedia.org)
  • varieties
  • However, it's important to remember that all varieties of watermelon can provide you with some great nutrient benefits, and not all nutrients reach maximum concentration along with maximal ripeness. (whfoods.com)
  • The Begoniaceae are known for their horticultural species, of which there are over 130 with many more varieties. (wikipedia.org)
  • Bailey
  • Although this error only occurred in 1930 (Bailey, Gentes Herbarum 2: 180-186), it has been perpetuated in hundreds of papers on the watermelon. (wikipedia.org)
  • stems
  • The watermelon is an annual plant with long, weak, trailing or climbing stems which are five-angled and up to 3 m (10 ft) long. (worldwidefruits.com)
