Flavonoids Found to Help Colorectal Health
By Greg Arnold, DC, CSCS, June 18, 2008, abstracted from “Dietary Flavonoids and Colorectal Adenoma Recurrence in the Polyp Prevention Trial” in the June 2008 issue of Cancer Epidemiology Biomarkers and Prevention

Colorectal cancer is the second leading cause of death from cancer (behind lung cancer) in the United States. It claims more than 55,000 Americans each year and poses a risk for nearly 1 in 4 Americans (80 to 90 million) because of age or other factors. It affects both men and women equally1.

Fortunately, a number of ways are available to help colon health, including calcium2, conjugated linoleic acid3, vitamin B64, green tea5, fiber6, olive oil7 apples8 and omega-3 fats9. Now a new study10 has found that flavonols, a group of over 5,000 compounds11 contained in almonds12 as well as fruits and vegetables13 that benefit colon health14, pancreas health15, and breast cell health16, may also help colorectal health.

In the study, researchers analyzed data on over 1,900 patients who participated in the Polyp Prevention Trail (PPT). This was a four-year randomized, multi-center, nutritional intervention trial that evaluated whether following a high-fiber diet (18 grams of fiber per 1,000 calories), high-fruit and high-vegetable (5 servings per day), and low-fat (no more than 20% of total calories) diet is effective in inhibiting colorectal adenoma recurrence17. The researchers found that total flavonoid intake did not significantly reduce the risk of having a recurrence of colorectal adenomas. However, there was a 36% reduced risk of having an advanced recurrence of adenomas in the highest flavonoid intake group (more than 106 mg per day) compared to the lowest intake (less than 51 mg per day).

When looking at specific flavonoids, they found that flavonols (more than 17.3 mg per day compared to less than 8.12 mg per day) and isoflavonoids (more than 0.133 mg per day compared to less than .045 mg per day) produced a 76% and 54% reduced risk of any recurrence, respectively. Flavonols are found mostly in apples, beans, broccoli, and onions while isoflavonoids are found mostly in bean and soy products.

For the researchers, “our data suggest that a flavonol-rich diet may decrease the risk of advanced adenoma recurrence.”

NEW POSTING

New fecal test for colon cancer
Colon Cancer


RanplexCRC is a diagnostic test that can detect 28 polymorphisms associated with colorectal cancer in a single stool sample. It does not require a hospital visit or dietary restrictions, while having greater sensitivity than the currently used Faecal Occult Blood (FOB) screening test. RanplexCRC may more accurately profile patients and reduce the number of patients for colonoscopy, saving time and resources and reducing patient discomfort.

Most sporadic colorectal cancers follow a well recognised progression from normal cells through adenoma (abnormal glandular growths) to cancer, driven by mutations in a small number of genes. RanplexCRC can simultaneously detect 28 mutations from four key genes in cancer or pre-cancer cells shed into the bowel. Selected mutations present in APC, KRAS, BRAF and Tp53, along with wild-type control sequences, are represented on 2 biochips detected using Randox's Biochip Array Analysers.

The Randox family of Biochip Array analysers are immunoassay testing platforms that work by combining panels of related tests on a single biochip. The chemiluminescent endpoint is detected by a CCD-camera and quantified by a custom image-processing software. Evidence, a fully automated analyser for high-throughput laboratories, and the Evidence Investigator, a semi-automated analyser for low-throughput laboratories and research purposes, are both available from Randox.

Bowel (colorectal) cancer is the second largest cause of cancer mortality in the western world, but up to 90% curable if detected early. Unfortunately, most patients present with advanced disease, reducing their long term survival. National Screening programmes are being introduced throughout Europe, to reduce CRC mortality, using the FOB test. This cheap and non-invasive test detects blood in stool samples, which may be an indication of a tumour. Patients with a positive FOB test are then referred for colonoscopy. The FOB test, however, suffers from poor sensitivity, as not all tumours bleed (false negative test) and not all stool-blood is derived from tumours (false positive test). Many patients (up to 50%) may therefore be sent for colonoscopies unnecessarily. Colonoscopies are invasive, involve dietary restrictions and require the presence of a surgeon, so an intermediate test would benefit both the patient and the healthcare system. RanplexCRC provides the answer, filtering out false positives.

I don't remember what Sheldon recommended but I seem to think it was not more than 1/2 - 1 cup water. I believe he said you should retain it as long as you could and even mentioned that he was able to retain it completely. Go back and re-read his posts.

Vitamin E is more theraputic and healing if you can get the complete form of it. A complete vitamin E supplement will list alpha, beta, delta and gama tochopherols and tocotrienols. Look for it on iherb.com. They ship overseas.

I found this at vitacost. It's cheaper at vitacost and they sell overseas too.
