Guest guest Posted November 22, 2001 Report Share Posted November 22, 2001 In response to my posting: << Well, that's not exactly a complete picture of canola. Canola can in no way compare to olive oil, which has been used in diet for thousands of years. Canola is a hybridized version of rapeseed that was developed by Canadian scientists. They specifically were trying to reduce naturally occuring poisons in rapeseed oil, erucic oil being the worst. >> Greg wrote: << And they succeeded. Commercial Canola has less than 0.5 % erucic acid. A scan of the papers on PubMed show NO toxicity or problems at this level. The latest version of the seed has reduced erucic even further. Many foods have been modified by food scientists over the years to reduce undesirable elements naturally occurring. You eat many of there foods every day, so why give the original rapeseed a bad rap it is NOT what current Canola is made from. With respect, please try to compare apples to apples. >> Greg, You seem to have trouble understanding what is being said. Canola oil has only been around for about fifteen years and does not have the ancient history of olive oil. When people compare the two, focusing on the saturated oil content while ignoring that canola oil contains a deadly toxin that olive oil does not, they are comparing apples with oranges while specifically hiding something. Apparently you do not like to admit that rapeseed and canola are related. Despite the fact that the erucic acid has been reduced in canola, it still occurs. We are not comparing apples and oranges here. Scientifically, canola is considered a type of rapeseed (brassica) and there are stern warnings about growing the fields together because rapeseed can pollinate canola and produce the higher levels of erucic acid. The following excerpt shows the language that the scientific and agricultural communities use when referring to rapeseed and canola (from www.ext.colostate.edu/pubs/crops/00110.html) . << New varieties of rapeseed, developed in Canada and Europe, are low in erucic acid and glycosinolates. These varieties are the so-called " doublelow " types and sometimes are marketed as canola. >> They keep lowering the erucic acid profile because it is a poison. The fact is that by law they can have up to 2% erucic acid. Even though some crops may yield lower amounts, other crops yield higher levels and they are not guaranteeing the level in the bottles people buy at stores. I think people should be informed that there is a little extra ingredient in canola that is a known poison. Let them decide whether they want to add that poison to their diets. Apparently your definition of " good science " is your opinion. When Lorenzo wrote about the PUBMED article reporting that cows had died after consuming large amounts of canola oil and asked if anyone believed they would have died after eating olive oil, you wrote: << Or car oil or massage oil or any other form of oil? >> Did you really not understand what was being said? He asked if consuming large amounts of olive oil would kill the cattle. You responded with nonedible oils. I believe you might really understand that there is a possible problem with canola when you compare it to toxic oils. Then, you wrapped up your response with: << How about comparing apples to apples and reporting the PubMed papers which show benefit to humans from Canola oil? With respect, this is not good science >> I'm not sure how we once again get comparing fruits out of this, but apparently it's your standard effort to pooh-pooh someone's point. And the " this is not good science " is another obvious cop-out. First, you do not address what is being said: do you truthfully think that olive oil would have killed the cattle? If so, why? You just blow some smoke with the apparent belief that if you disagree with someone, you don't have to address their point, just mention comparing apples with apples and mention " not good science. " You state that PUBMED has articles showing that canola is good for one's health. Why don't you bring them up? It is your contention that canola is good for health, but offer no studies. One of the most widely cited studies is the Lyon Study. Here's an excerpt that appeared at the Canola Council's own website. << • Results from the long term and well-designed " Lyon Heart Diet Study " study demonstrated that over the course of close to four years, a Mediterranean-type diet reduced the risk of a second heart attack and overall death rate by as much as 70%. Canola oil based margarines were included as a constituent in the dietary protocol. Even though several antioxidant-rich foods, including vegetable and fruits as well as omega-3 EFA rich fish were also consumed, only the EFA alpha- linolenic acid from the canola oil margarine was significantly related to a reduction in heart attacks. The researchers concluded that dietary changes such a reduction in the total intake of saturated fats and an increase in intake of alpha-linolenic acid through the consumption of canola oil can lead to significant reductions in mortality from CHD9. >> The conclusion is extemely unscientific: Change people's diet to one that is known to be healthy, and tell them to include canola margarine (margarine is known for having unhealthy trans fatty-acids). When their health improves, credit the canola margarine. No. An honest test would to take two groups and change only one element: their margarine/butter source.

Canola oil has only been around for about fifteen years and does not have the ancient history of olive oil. When people compare the two, focusing on the saturated oil content while ignoring that canola oil contains a deadly toxin that olive oil does not, they are comparing apples with oranges while specifically hiding something. ** ALL foods contain some toxins. Almonds contain arsenic. What is the determinate factor is at what level the toxin causes problems and at what level the toxin occurs in the food. This is what science is medical / food about. Apparently you do not like to admit that rapeseed and canola are related. Despite the fact that the erucic acid has been reduced in canola, it still occurs. ** Sure, just like arsenic occurs in almonds. Apparently your definition of " good science " is your opinion. When Lorenzo wrote about the PUBMED article reporting that cows had died after consuming large amounts of canola oil and asked if anyone believed they would have died after eating olive oil, you wrote: ** Good science would have gives other cows the same dose of other oils and observed the effects. Bad science is taking one example and applying it incorrectly. Did you really not understand what was being said? He asked if consuming large amounts of olive oil would kill the cattle. You responded with nonedible oils. I believe you might really understand that there is a possible problem with canola when you compare it to toxic oils. ** I understand the researchers found NO cause of death. You think they didn't look for high erucic acid in the cow's blood and tissues?. As they found NO cause, you can assume erucic acid was NOT the cause. With respect Lorenzo's and your reply is a example of how it is easy to take data out of context and make it suite other purposes. While is was good to see Lorenzo using PubMed, is was disappointing he didn't list some of the papers showing the health benefits from canola. Viweing data with only one eye will always reveal exactly what you seek to find. << • Results from the long term and well-designed " Lyon Heart Diet Study " study demonstrated that over the course of close to four years, a Mediterranean-type diet reduced the risk of a second heart attack and overall death rate by as much as 70%.

Hi Kathy, The Lyon Heart sudy was one of the most closely controlled studies in the world. There was a control group which did not use canola and experienced normal heart attack and death rates. In the canola group there were NO cardio deaths and in fact the study was stopped after about 2 years and both groups placed on the canola diet due to the strong result. The lack of deaths and the use of canola were the only two significant variations between the two groups. ======================== Good Health & Long Life, Greg Watson, gowatson USDA database (food breakdown) http://www.nal.usda.gov/fnic/foodcomp/ PubMed (research papers) http://www.ncbi.nlm.nih.gov/entrez/query.fcgi DWIDP (nutrient analysis) http://www.walford.com/dwdemo/dw2b63demo.exe KIM (omega analysis) http://ods.od.nih.gov/eicosanoids/KIM_Install.exe Quote Link to comment Share on other sites More sharing options...
