The next days should be good ones surrounded with good friends and family, but I leave you with an important article entitled, “Eat to Save Your Life Another Half-True Diet Book”.
I leave you with some points made in the article….
- “The “one true cause” fallacy: The book opens with an interesting review of vitamin C deficiency, noting that it (apparently) took the British Royal Navy 40 years before they accepted that the treatment for scurvy was citrus extract (rather than flogging). Citing this incident as an example of nutritional deficiency leading to life-threatening illness, it’s a short ride to the “one true cause” fallacy whereby the authors postulate that there are untold numbers of modern diseases caused by unrecognized nutritional deficiency syndromes. Nutritional deficiency may be the one true cause of most diseases, you see.
- The appeal to research without references. Countless appeals are made to “mounting evidence” of this and that (arthritis being caused primarily by food-related inflammation for example), either without reference footnotes, or with mentions of sources of dubious credibility (such as the Canadian Association of Naturopathic Doctors).
- The appeal to supplements in lieu of vaccines. No diet advice would be complete without a gratuitous attack on vaccines, right? The authors suggest that flu vaccines (for example) only provide immunity for 2 months “and only for certain individuals.” Meanwhile, they assert that a combination of Echinacea, garlic, and vitamin C support the immune system to successfully fight of viruses. These claims are simply unproven and multiple studies have already found no benefit (over placebo) of these supplements at preventing and treating the common cold.
- Over-diagnosis. If you think that the world of medicine is predisposed to seeing disease where there is none, try the alternative medicine world. The authors assert that everything from zits, to rashes, to “brain fog” are potential signs of grave underlying immune compromise – caused by, you guessed it, dietary deficiencies.
- Over-supplementation. The authors argue that “supplementation is a necessity in our nutrient-robbed world.” However, new evidence doesn’t support supplementation for the general population, though it had beentraditionally felt that multi-vitamins might be valuable. In addition, new studies are finding that food sources are preferable to supplements for daily nutritional requirements (such as calcium) and that anti-oxidants such as vitamin E may do more harm than good.
- The “organic is more nutritious” argument. Although a recent systematic review of the scientific literature found no support for the notion that organic foods contain more nutrients than those grown with traditional methods, the authors attribute Americans’ supposed vitamin deficiencies to poor soil quality caused by non-organic farming methods.
- Nutrigenomics and DNA hype. The authors do not take a sufficiently skeptical view of the emerging field of nutrigenomics (whereby certain foods and supplements are recommended to individuals based on their genetic profiles). They even suggest that nutrigenomic testing is so much fun, it’s “almost like being part of a CSI television show.” Who cares if it’s no more accurate than fortune telling”?
