Cancer, Gulliver, cat and mouse

Forget fruit and veg. Lose weight and cut the booze to reduce cancer risk
People should be warned that cancer is linked to obesity and alcohol, rather than urged to eat more fruit and vegetables to protect against the disease.

UK trialling testing sugar-coated salt on roads
Although they’ve been using molasses for years in Nebraska and other places to help salt stick to the roads, it’s only just occurred to us Brits to give it a try now that we’re entering a period of severe cold weather (again). Add salt to water and it lowers its freezing point so that it has to be that bit colder for the roads to stay frozen. However, salt kicks up too easily, add molasses and the salt gets more of a purchase on the icy roads and helps defrost them (ever so slightly) producing a nice brown slush.

Stuart Little does a Benjamin Button
Researchers have identified targets (related to the enzyme telomerase) that could help produce old-age-defying drugs and a fountain of youth for the baby boomer population… but haven’t we heard this all before? Of course, we have. It’s unlikely ever to come to anything more than next-generation Botox.

Gulliver Turtle is looking for candidates for BioMed Central’s 5th Annual Research Awards
BioMed Central’s Research Awards are now in their fifth year and apparently growing in popularity. The awards were set up to recognize excellence in research that has been made universally accessible by open access publication, so get your nominations in and see if Gulliver picks you.

Cat and mouse
No sooner do the US authorities begin stealing web domains illegally (actually just taking out the domain from DNS servers), than users find a way to fight back using a DNS system that cannot be touched by any governmental institution and works a P2P network. The problem being that an innocent party might have their domain blocked by the US before due process has taken place and on spurious grounds (and all this before the legislation even comes into effect).

One thought on “Cancer, Gulliver, cat and mouse”

  1. “Forget fruit and veg. Lose weight and cut the booze to reduce cancer risk”

    I wrote this letter to Professor Key.

    Professor Key,

    Regarding this research finding “Fruit and vegetables do not protect against overall risk of cancer,” I’m curious to know whether your group has studied tissue concentrations of omega-6 and omega-3 fatty acids in relation to cancer incidence. As you probably know, the insertion of seed oils into the food supply over the past hundred years has dramatically increased the omega-6 component of total fat intake. [1]

    Oddly enough, there appears to be little interest in publicizing the results of researches elucidating the impact of this uncontrolled experiment on the physical and mental health of humans. [2] Rather, what I’ve observed is a great deal of publicity regarding the therapeutic benefits of omega-3s. Yet, as early as 1999 some American scientists were recommending reduced intake of omega-6s to increase the therapeutic benefits of omega-3s. [3] Here’s what they said:

    “One recommendation deserves explanation here. After much discussion consensus was reached on the importance of reducing the omega-6 polyunsaturated fatty acids (PUFAs) even as the omega-3 PUFAs are increased in the diet of adults and newborns for optimal brain and cardiovascular health and function. This is necessary to reduce adverse effects of excesses of arachidonic acid and its eicosanoid products. Such excesses can occur when too much LA and AA are present in the diet and an adequate supply of dietary omega-3 fatty acids is not available. The adverse effects of too much arachidonic acid and its eicosanoids can be avoided by two interdependent dietary changes. First, the amount of plant oils rich in LA, the parent compound of the omega-6 class, which is converted to AA, needs to be reduced. Second, simultaneously the omega-3 PUFAs need to be increased in the diet. LA can be converted to arachidonic acid and the enzyme, {Delta}-6 desaturase, necessary to desaturate it, is the same one necessary to desaturate LNA, the parent compound of the omega-3 class; each competes with the other for this desaturase. The presence of LNA in the diet can inhibit the conversion of the large amounts of LA in the diets of Western industrialized countries which contain too much dietary plant oils rich in omega-6 PUFAs (e.g. corn, safflower, and soybean oils). The increase of LNA, together with EPA and DHA, and reduction of vegetable oils with high LA content, are necessary to achieve a healthier diet in these countries.”

    The above excerpt is from an article entitled Workshop on the Essentiality of and Recommended Dietary Intakes for Omega-6 and Omega-3 Fatty Acids which was published in Journal of the American College of Nutrition, Vol. 18, No. 5, 487-489 (1999)

    In the portion of your British Journal of Cancer article that I was able to access you noted, “Current advice in relation to diet and cancer should include the recommendation to consume adequate amounts of fruit and vegetables, but should put most emphasis on the well-established adverse effects of obesity and high alcohol intakes.” [4]

    I’m just a layman but over the past three decades I have read extensively about both alcohol abuse and obesity. My conclusion is that both of these problems are strongly correlated with excessive omega-6 intake which automatically induces an omega-3 deficiency state. [5]
