FRUIT TREES THAT HAVE BEEN SHOWN TO KILL CANCER CELLS OF THE BREAST
Recent studies show that women who want to reduce the risk of breast cancer should consume at least 75 grams of citrus fruit or its juice a day as part of a balanced, healthy lifestyle. Most benefits offered oranges and grapefruit.
A new study of the University of Western Ontario, London, for the first time shown that limonoids, natural compounds present in lemons and oranges and other citrus fruits, interfere with ER + and ER- breast cancer . This sheds new light on the importance of citrus in the prevention of breast cancer and supports previous research that has shown that the consumption of fruit may reduce the risk of breast cancer.
As part of the study 14 kilograms of dry seeds of lemon is degreased and pulverized. Nine different limonoids is extracted from the seed. Seven showed significant cytotoxicity against ER + breast cancer cells, while four showed cytotoxicity against ER-cells (reduced growth / vitality by 44 percent). We examined the ability and limonoids in causing the death of cancer cells. It has been shown that the most potent lemon glucoside.
They also tested the ability of limonoids to inhibit aromatase, which is the key to limiting the estrogen hormone ER + cancer cells can be used for growth. Limonoids have been shown to be as natural aromatase inhibitors, and again, lemon glucoside been at the forefront as the most powerful among them. Thus, limonoids are natural poison for ER + and ER- breast cancer cells, and simultaneously denying estrogen ER + cells, which is required for the growth hormone.
Preventing breast cancer is not the only reason for eating citrus limonoids. In laboratory experiments, such as those conducted by the University of Texas A & M limonoids showed cytotoxicity to cancer, colon cancer, and other diseases. This raises an important question: How much citrus we have to consume for a meaningful protection against cancer?
Citrus fruit in cancer prevention - How much is needed?
A recent study of couples from Europe showed that eating four or more servings of 150 g of citrus per week reduces the risk of throat cancer by 58 percent, oral / pharyngeal cancer by 53 percent and stomach cancer by 31 percent, and colorectal cancer 18 percent, announced Istituto di Ricerche with Farmacologiche Mario Negri in Milan.
A recent US study found that women who consume about 75 grams of grapefruit (or fruit juice) per day have a 22 percent reduction in the risk of breast cancer (in case you have never used hormone replacement therapy). It is important to note that the consumption of citrus fruits, which brought protection nearly identical in both studies (525-600 grams per week), and can be interpreted as the minimum level for meaningful protection from cancer.
Sources citrus limonoids - from oranges are the best
While limonoids from recent studies extracted from the seeds of lemon, they can be found in the bark, pulp, and juice of citrus fruits. Citrus juices contain about 90 to 300 mg per liter of limonoids, glucoside (orange juice: 300 mg / l, grapefruit juice: 200 mg / l, lemon or lime juice: 90 mg / l).
Fruit rind contains up to 500 mg / kg of limonoid and citrus fruit stones may contain up to two percent by weight, provided that the grapefruit seed richest them.
The studies show that women who want to reduce the risk of breast cancer should consume at least 75 grams of citrus fruit or juice a day as part of a balanced, healthy lifestyle. Most benefits offered oranges and grapefruit.
