    Epidemiological evidence suggests that diets rich in tomatoes and tomato products may be protective against risk for certain cancers, especially prostate cancer. The carotenoid lycopene has received the most attention as the compound in tomatoes responsible for this noted decrease in cancer risk. In raw, red tomatoes, approximately 95% of the total lycopene is present in the all-trans form. Despite the predominance of dietary all-trans-lycopene, cis-isomers account for 58-73% of total lycopene in human serum, and a surprisingly high 79-88% in benign or malignant prostate tissue. This observation is related to isomerization in vivo, as demonstrated by conventional and tracer...

    A diet full of red vegetables, like tomatoes, apricots, guavas and watermelons may prevent men from developing prostate cancer, according to Barbara Quinn, a nutritionist affiliated with the Community Hospital of the Monterey Peninsula. The secret of red vegetables would lie on a substance called lycopene.
  • Tomatoes found to contain nutrient which prevents vascular diseases

    They are the most widely produced fruit in the world and now scientists in Japan have discovered that tomatoes contain a nutrient which could tackle the onset of vascular diseases. The research, published in the journal Molecular Nutrition & Food Research, reveals that an extracted compound, 9-oxo-octadecadienoic, has anti-dyslipidemic affects. The team led by Dr Teruo Kawada, from Kyoto University and supported by the Research and Development Program for New Bio-industry Initiatives, Japan, focused their research on extracts which tackle dyslipidemia, a condition which is caused by an abnormal amount of lipids, such as cholesterol or fat, in the blood...

    BOSTON, Mass. (July 26, 2009) — High-throughput sequencing has turned biologists into voracious genome readers, enabling them to scan millions of DNA letters, or bases, per hour. When revising a genome, however, they struggle, suffering from serious writer's block, exacerbated by outdated cell programming technology. Labs get bogged down with particular DNA sentences, tinkering at times with subsections of a single gene ad nauseam before moving along to the next one. A team has finally overcome this obstacle by developing a new cell programming method called Multiplex Automated Genome Engineering (MAGE). Published online in Nature on July 26, the platform...

    Watering Tomato Plants With Diluted Seawater Boosts Levels Of AntioxidantsWatering tomato plants with diluted seawater boosts levels of antioxidants, scientists report. (Credit: Courtesy of ScienceDaily (Apr. 29, 2008) — Watering tomatoes with diluted seawater can boost their content of disease-fighting antioxidants and may lead to healthier salads, appetizers, and other tomato-based foods, scientists in Italy report. Besides their use in a variety of ethnic food dishes, tomatoes are one of the most commonly grown home garden vegetables, particularly cherry tomatoes. Scientists have linked tomatoes to several health benefits, including protection against prostate cancer and heart disease. Researchers have known...
  • Broccoli and Other Vegetables Linked with Decreased Risk of Aggressive Prostate Cancer

    Eating more cruciferous vegetables like broccoli and cauliflower is associated with a reduced risk of aggressive prostate cancer. Several studies have demonstrated an association between eating vegetables and a reduced risk of prostate cancer, but study results have not been consistent and many have not investigated the association among patients with aggressive prostate cancer. Victoria Kirsh, Ph.D., of Cancer Care Ontario in Toronto and colleagues evaluated the possible association in 1,338 prostate cancer patients diagnosed in the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial. Each of the men completed a 137-item food-frequency questionnaire. They found that eating fruits and...
  • Unique Tomatoes Tops in Disease-Fighting Antioxidants

    Deep red tomatoes get their rich color from lycopene, a disease-fighting antioxidant. A new study, however, suggests that a special variety of orange-colored tomatoes provide a different form of lycopene, one that our bodies may more readily use. Researchers found that eating spaghetti covered in sauce made from these orange tomatoes, called Tangerine tomatoes, caused a noticeable boost in this form of lycopene in participants' blood. "While red tomatoes contain far more lycopene than orange tomatoes, most of it is in a form that the body doesn't absorb well," said Steven Schwartz, the study's lead author and a professor of...

    CAROTENOIDS MAY PROTECT AGAINST PROSTATE CANCER   Asians are well known to have a low incidence of prostate cancer. Australian and Chinese researchers conducted what is called a "case-control study" in southeast China, the first of its kind in an Asian population. They discovered that dietary lycopene and other carotenoids may protect against prostate cancer.   The researchers compared 130 patients with adenocarcinoma of the prostate to 274 controls - men who were in the hospital for conditions other than prostate cancer. They found that the more carotenoid-rich foods the men ate, the less their risk of developing prostate cancer....
  • Israeli scientists explain how tomatoes prevent cancer

    Scientists at Ben-Gurion University of the Negev have identified why it is good for us to consume large quantities of tomatoes - and say that the best way to eat them is cooked up with some olive oil and cheese. Scientists have long believed that the carotenoids found in fruits and vegetables have a cancer preventive effect. In particular, studies have found that as the consumption of tomato products increases, risk of certain types of cancer decreases - even more so than when a variety of vegetables are eaten. Over the years, studies have found that the risk of up...
