Anti Cancer Benefits of Tomatoes

 tomatoes
The tomato originates from Central and South America, with Mexico being the first known cultivators. The conquistadors took seeds back to Spain, and soon became popular in other European countries.

Strangely enough, it was first grown only for ornamental purposes in Italy for fear that it was poisonous due to the fact that it belongs to the nightshade family. And it was for the same reason that they were not popular in the United States until 1820.

Today China is the world’s largest producer, followed by the United States and Turkey.

Health Benefits of Tomatoes

  • Nutrients
    Tomatoes are an excellent source of vitamin A, C, and K. They a very good source of dietary fiber, chromium, manganese, potassium, and vitamin B1. They are a good source of magnesium, folate, phosphorus, niacin, vitamin E, B6 and B2, copper, pantothenic acid, iron, and protein.
  • Glycemic Index (GI)
    In a study to determine the estimated GI of various foods, it was concluded that canned tomato juice and tomato soup has a low GI of 38.
  • Antioxidants
    At a study at the Department of Food Science, at Cornell University, New York it was shown that strawberries contain high levels of antioxidants, which can decrease the risk of chronic disease. They were also shown to significantly reduce liver cancer cells. In addition to their known beneficial effects on cancer and heart disease, the antioxidant qualities of strawberries may also be beneficial in reversing the course of neuronal and behavioural aging.
  • Cancer
    Ellagic acid is present in many red fruits and berries, including raspberries, strawberries, blackberries and cranberries. Studies have shown that strawberry consumption can increase anti-cancer activity on cancer cells of the breast, oesophagus, skin, colon, prostate and pancreas. More specifically, ellagic acid prevents the destruction of P53 gene by cancer cells. Ellagic acid can also bind with cancer causing molecules, thereby making them inactive.
  • Alzheimer’s Disease
    Due to their positive effects against anti-neurodegenerative diseases, strawberries are helpful in slowing the onset and reduce the effects of Alzheimer’s disease.
  • Heart Health
    Strawberries have also been linked with effecting blood vessels, platelets and lipoproteins positively, which can reduce the risk of coronary heart diseases.
  • Anti Inflammatory
    Strawberry extracts have also been shown to inhibit COX enzymes in vitro, which inhibits the inflammatory process.
