food for thought: organics and food safety
psycho bitch Lesley fantasized:
> I'll repeat - veganic farming Is the flawed pseudo-intellectual product of urban vegans who object to Nature. You won't find "veganic" grains or legumes, much less "veganic" produce, at the supermarket. Leave it to someone who believes in "inner earth beings" to promote clueless urbanite pipedreams. BTW, is your horse trading compatible with "veganic" principles? |

How effective is garlic? Research on medicinal uses of allicin in fresh garlic indicate it can lower blood pressure and cholesterol. Ajoene may be useful in slowing blood clotting. In this way, garlic protects against heart disease and stroke. These results do not apply to garlic supplements, however. Studies also show that fresh garlic, in large quantities, can lower cholesterol levels. Because garlic thins the blood, it may lower blood pressure. Other findings suggest that high levels of garlic may prevent development of cancer by stimulating the immune system and hindering growth of cancer cells. Labora- tory studies show that garlic can inhibit bacteria growth and may fight infection. However, those results are unproven in humans. http://tinyurl.com/zb3qt Not much, eh. Just as I suspected. |

Just as I suspected. Not much! If it was a drug, you'd be SINGING its praises! How did you 'miss' this??? : Protection against Helicobacter pylori and Other Bacterial Infections by Garlic1 Gowsala P. Sivam Bastyr University, Research Institute, Kenmore, WA 98028 ABSTRACT Louis Pasteur was the first to describe the antibacterial effect of onion and garlic juices. Historically, garlic has been used worldwide to fight bacterial infections. Allium vegetables, particularly garlic (Allium sativum L.) exhibit a broad antibiotic spectrum against both gram-positive and gram-negative bacteria. Noteworthy results published include the following: 1) raw juice of garlic was found to be effective against many common pathogenic bacteria-intestinal bacteria, which are responsible for diarrhea in humans and animals; 2) garlic is effective even against those strains that have become resistant to antibiotics; 3) the combination of garlic with antibiotics leads to partial or total synergism; 4) complete lack of resistance has been observed repeatedly; 5) even toxin production by microorganisms is prevented by garlic. Helicobacter pylori (H. pylori) is a bacterium implicated in the etiology of stomach cancer and ulcers. The incidence of stomach cancer is lower in populations with a high intake of allium vegetables. We have demonstrated in vitro that H. pylori is susceptible to garlic extract at a fairly moderate concentration. Even some antibiotic-resistant H. pylori strains are susceptible to garlic. Clinical trials are necessary to explore the possibility of using garlic as a low-cost remedy for eradicating H. pylori. KEY WORDS: . garlic . Allium . antibacterial activity . Helicobacter pylori http://jn.nutrition.org/cgi/content/...ct/131/3/1106S 'In ancient times, garlic was used for the treatment of cancer of the uterus (Hartwell, 1960; Essman, 1984; Doetsch, 1989; Konvicka, 1983). Numerous reports, including several important epidemiological studies, have entered the scientific literature ever since, asserting that garlic has a favourable effect of various forms of cancer. The following provides an overview of the current research and points of view concerning this very interesting special area of medicine. ... A very important epidemiological (prospective cohort) study for Americans has recently been published in which the intake of 127 foods (including 44 vegetables and fruits) was determined in 41,387 women (ages 55-69) followed by a five-year monitoring of colon cancer incidence (Steinmetz et al., 1994). The most striking result of this "Iowa Women's Health Study" was the finding that garlic was the only food which showed a statistically significant association with decreased colon cancer risk. For cancers anywhere in the colon, the modest consumption of one or more servings of garlic (fresh or powdered) per week resulted in a 35% lower risk, while a 50% lower risk was found for cancer of the distal colon. Although this study of 127 foods did not include onions, several other epidemiological studies have shown that onions and other Allium species are usually associated with decreased gastrointestinal cancer risk. Although the results have been less consistent than with garlic (Steinmetz & Potter, 1991, 1993; Haenszel et al., 1972; You et al., 1989; Cook-Mozaffari et al., 1979; Tajima & Tominaga, 1985; Shu et al., 1993; Tuyns et al., 1992; Graham et al., 1994; Levi et al., 1993a, 1993b) ......' http://www.garlic.mistral.co.uk/cancer.htm |

Correct, not much: Thirty-seven randomized trials, all but one in adults, consistently showed that compared with placebo, various garlic preparations led to *SMALL*, statistically significant reductions in total cholesterol at 1 month (range of average pooled reductions 1.2 to 17.3 milligrams per deciliter [mg/dL]) and 3 months (range of average pooled reductions 12.4 to 25.4 mg/dL)...Eight placebo-controlled trials reported total cholesterol outcomes at 6 months; pooled analyses showed NO SIGNIFICANT REDUCTIONS of total cholesterol with garlic compared with placebo. It is not clear if statistically significant positive short-term effects?but negative longer term effects?are due to: systematic differences in studies that have longer or shorter followup durations; fewer longer term studies; or time-dependent effects of garlic.... Twenty-seven small, randomized, placebo-controlled trials, all but one in adults and of short duration, reported MIXED BUT NEVER LARGE effects of various garlic preparations on blood pressure outcomes. Most studies did not find significant differences between persons randomized to garlic compared with those randomized to placebo.... Twelve small, randomized trials, all in adults, suggested that various garlic preparations had NO CLINICALLY SIGNIFICANT EFFECT on glucose in persons with or without diabetes. Two small short trials, both in adults, reported NO STATISTICALLY SIGNIFICANT EFFECTS of garlic compared with placebo on serum insulin or C peptide levels. Ten small, randomized trials, all but one in adults and of short duration, showed promising effects of various garlic preparations on platelet aggregation and mixed effects on plasma viscosity and fibrinolytic activity. Because the trials had only 409 participants, short followup periods, unclear randomization processes, no intention-to-treat analyses, missing data, and variability in techniques used to assess outcomes, NO FIRM CONCLUSIONS CAN BE DRAWN. There were INSUFFICIENT DATA to confirm or refute effects of garlic on clinical outcomes such as myocardial infarction and claudication. One 3-year randomized trial with 492 participants found NO STATISTICALLY SIGNIFICANT DECREASES in numbers of myocardial infarctions and deaths when placebo was compared with 6 to 10 grams of garlic ether extract.... SCANT DATA, primarily from case-control studies, suggest, but DO NOT PROVE, dietary garlic consumption is associated with decreased odds of laryngeal, gastric, colorectal, and endometrial cancer and adenomatous colorectal polyps. Single case-control studies suggest, but DO NOT PROVE, dietary garlic consumption is NOT associated with breast or prostate cancer.... ADVERSE EFFECTS of oral ingestion of garlic are "smelly" breath and body odor. Other possible, but not proven, adverse effects include flatulence, esophageal and abdominal PAIN, small intestinal OBSTRUCTION, contact DERMATITIS, RHINITIS, ASTHMA, BLEEDING, and MYOCARDIAL INFARCTION. Conclusions There are insufficient data to draw conclusions regarding garlic's effects on clinical cardiovascular outcomes such as claudication and myocardial infarction. Garlic preparations may have small, positive, short-term effects on lipids; whether effects are sustainable beyond 3 months is unclear. Consistent reductions in blood pressure with garlic were not found, and no effects on glucose or insulin sensitivity were found. Some promising effects on antithrombotic activity were reported, but few data are available for definitive conclusion. Using "any" garlic supplement for less than 3 to 5 years was not associated with decreased risks of breast, lung, gastric, colon, or rectal cancer. Some case-control studies suggest that high dietary garlic consumption may be associated with decreased risks of laryngeal, gastric, colorectal, and endometrial cancers, and adenomatous colorectal polyps. Multiple adverse effects, including smelly breath and body odor, dermatitis, bleeding, abdominal symptoms, and flatulence, have been reported. Whether adverse effects occur more commonly with certain preparations than others was not established. Furthermore, the causality of the adverse effects was not clear, except for breath and body odor, and the expected frequency of adverse effects was not determined. http://www.ahrq.gov/clinic/epcsums/garlicsum.htm |

If it were a drug, you'd have to be a lot more careful about your crazy and unfounded claims: Garlic is frequently touted as a remedy for high blood pressure, blood sugar imbalances, and arterial plaque. Some advocates even claim that garlic can prevent or cure cancer. But according to the National Center for Complimentary and Alternative Medicine, although garlic may have some health benefits, its reputation as a miracle remedy is not supported by available research. http://www.faqs.org/nutrition/Pre-Sma/Quackery.html However, the epidemiologic data do have some limitations, which decrease the strength of the evidence currently available. For example, consumption is often reported as frequency instead of amount consumed, and the consumption categories differ widely among studies. In addition, the meta-analysis (120) indicated that the apparent protective effect found between Allium vegetable consumption and cancers of the stomach and colon may have been overestimated, suggesting a possible publication bias. Lack of adjustment in the statistical analyses also limits the strength of the conclusion. For example, the data for stomach cancer were generally not adjusted for fruit and vegetable consumption, which are known to be protective and could therefore be a confounder in the analysis. Clinical trials are not currently available, but they could be useful for assessing the ability of garlic and other Allium vegetables to prevent cancer or preneoplastic lesions. There are difficulties in standardizing the real intake of Allium vegetables, and in estimating the composition in organosulfur compounds and other chemicals. In addition, these trials cannot use cancer as the end point and should therefore rely on surrogate intermediate biomarkers (121). Such end points are not fully validated, and further research is needed to develop and validate suitable biomarkers. http://www.ehponline.org/members/200...-full.html#con |

> Not much! If it was a drug, you'd be SINGING its praises! No, but I'm not surprised you a Numerous controlled trials have examined the effects of oral garlic on serum lipids. Most studies have been small (<100 subjects), with poorly described design and results, and most have reported non-significant modest benefits... Small reductions in low-density lipoprotein (LDL) (by <10mg/dL) and triglycerides (by <20mg/dL) may also occur in the short-term, although results have been variable. High-density lipoprotein (HDL) levels are not significantly affected. Long-term effects on lipids or cardiovascular morbidity and mortality remain unknown. Small reductions in blood pressure (<10mmHg), inhibition of platelet aggregation, and enhancement of fibrinolytic activity have been reported, and may exert effects on cardiovascular outcomes, although evidence is preliminary in these areas. Numerous case-control/population-based studies suggest that regular consumption of garlic (particularly unprocessed garlic) may reduce the risk of developing several types of cancer, including gastric and colorectal malignancies. However, prospective controlled trials are lacking. Multiple cases of bleeding have been associated with garlic use, and caution is warranted in patients at risk of bleeding or prior to some surgical/dental procedures. Garlic does not appear to significantly affect blood glucose levels. http://www.nlm.nih.gov/medlineplus/d...nt-garlic.html Check out the scorecard on the above link. One B, a couple Ds, the rest Cs.

If it was a drug, you'd be SINGING its praises! > > Correct, So, I see you've moved the goalposts. You also omitted the section on limitations from your post. In reference to what was considered: 'Limitations Notable limitations in summarizing findings from garlic research include the substantial variability in types of garlic and garlic preparations that have been studied and an inadequate definition of the active, biologically available constituents in the various preparations. In addition, many trials that evaluated the effects of garlic on cardiovascular-related endpoints are limited by short durations; inadequate randomization and blinding procedures; lack of clear specification of contents of garlic preparations- including their constituents and dissolution properties; lack of intention-to-treat analyses; and incomplete reporting of data. The meta-analysis we performed is limited by some missing data at different time points and by the need to impute variability data from some trials. http://www.ahrq.gov/clinic/epcsums/garlicsum.htm Too busy messing about with animals, 'disease' and chemicals, innit. Treatment with garlic can't, and isn't meant to replace a healthy diet. It has its place as an aid in treatment, and as part of a healthy diet. Nutrition in Clinical Care Volume 3 Page 145 - June 2000 doi:10.1046/j.1523-5408.2000.00043.xVolume 3 Issue 3 Garlic and Cardiovascular Disease Michelle H. Loy Richard S. Rivlin, MD Nutr Clin Care. 2000;3:145-152 Abstract The goal of this review is to evaluate the current status of knowledge concerning cardiovascular effects of allium derivatives from garlic and to identify potential areas of future research. To date, the cardiovascular actions most studied include lipoprotein metabolism, hypertension, thrombosis, and antioxidant capacity. There are also some preliminary findings suggesting that garlic may lower elevated serum levels of homocysteine. Epidemiological, clinical, and laboratory studies have reported that garlic contains many biologically and pharmacologically active compounds. The majority of studies show that garlic lowers total serum cholesterol and LDL-cholesterol; inhibition of HMG-CoA reductase or squalene epoxidase appears to be the major mechanism. Lowering of blood pressure likely results from inhibition of angiotensin- converting enzyme activity. Antithrombosis effects may be related to inhibition of adenosine deaminase. Antioxidant effects may be related to the inhibition of lipoxygenase. The published studies in their aggregate suggest that appropriate usage of allium derivatives from garlic may potentially play a role in the maintenance of optimal cardiac function. Further research is needed to examine the structure-function relationships of the various allium derivatives of garlic, the amounts in foods and supplements required for efficacy, and the possible effects of combining garlic with other nutrients and medications. The mechanisms of action of allium derivatives on various aspects of cardiac function require further clarification. http://www.blackwell-synergy.com/lin...8.2000.00043.x |

Some quotes to inspire your googling: GARLIC EXTRACT (from 66 mg fresh garlic) were found to be effective antibiotic agents against many bacteria, including Staphylococcus aureus, Escherichia coli, salmonella enteritidis, Klebsiella pneumoniae, and mycobacteria.45,46,47 These studies compared the antimicrobial effects of garlic with those of commonly used antibiotics, including penicillin, streptomycin, chloramphenicol, erythromycin, and tetracyclines. These studies demonstrated garlic's efficacy in inhibiting the growth of some bacteria that had become resistant to one or more of the antibiotics. Garlic possesses important immune-enhancing and anticancer properties. Human studies show that garlic inhibits the formation of nitrosamines which are powerful cancer-causing compounds formed during digestion.48 Garlic has demonstrated significant antifungal activity against a wide range of fungi. Garlic is especially active against C. albicans, being more potent than Nystatin and six other reputed antifungal agents.49 Garlic's antiviral effects have been well studied. In vitro, fresh garlic killed herpes simplex types 1 and 2, para-influenza virus type 3, vesicular stomatitis virus, and human rhinovirus type 2. Fresh garlic extract was virucidal against all viruses tested but the virucidal activity of commercial products depended how they were prepared. Those products producing the highest level of allicin and other thio-sulfinates, such as found in Factor Twelve: Opti-cillin, had the best virucidal activity.50 (from http://www.doctorsexercise.com/produ...n/factor12.htm) > > Another problem is this vestige of the monarchy system > > that we still have hanging around, known as "intellectual property > > law". > > What's wrong with copyrights, patents, and other forms of protecting > one's work? > What's wrong is that free market forces are effectively eliminated.

But that's just my impression.... I appreciate your curiosity Frant. I think you are basically right. So, why did the news make me want to go get some org. spinach of my own? Perhaps it is like the stories of heroin users, inspired by others overdoses to find some from the same batch.. the really good stuff. Perhaps it is my general rebellion against microbe-phobia. I certainly acknowledge the huge progress made in keeping our sewage out of the streets and the rats out of out of our cupboards. However, I feel it is important to maintain healthy and evolving stomach flora and fauna. I almost always drink the local water - at least some. Garbaging is not only a great way to get food but to maintain a strong stomach ecosystem. I'm willing to bet I've been exposed to O157:H7. Perhaps it is my love of natural foods, that can maintain life. Sure, a pasteurized and homogenized and preserved cooked spinach wouldn't harbor O157:H7.. but I'm willing to take that risk for live food. The news said the spinach had life in it, and maybe I was attracted by that. Or perhaps I'm just an anti-social goat-sucker walking neurotic with a death-wish. Cheers - |
