Dear Readers,

We hope you find the True North Tune-Up useful. The studies are from peer-reviewed scientific journals with rare exceptions, like the internal EPA review in the second link, or the abstracts from the cancer prevention meeting.

To your health,

Exercise reduces the risk of dementia.
Among 1740 adults over 65 followed for 6 years, dementia developed in 158.  Those who exercised three or more times a week developed dementia at 62% the incidence of those who exercised fewer than three times a week. While this does not prove a causal connection, the association suggests that low levels of exercise cause a 30-40 percent reduction in risk for dementia.

Exercise might be especially important in those with family members who have been affected with dementia, as a study this month of Swedish twins shows a role for inheritance in from 58 to 79 percent of cases.

EPA bans cookware chemicals.
Perfluorooctanoic acid (PFOA) is used to make things like microwavable popcorn bags, french fry containers, frying pans, stain and stick-resistant. PFOA is an exclusively manmade synthetic chemical, now found in the blood of 95% of Americans. The EPA Federal Register document cites rodent studies (scroll halfway down the next link) showing  PFOA causing liver, immune, developmental problems and cancers.

In December 2005 DuPont agreed to pay $12 million in fines to resolve federal charges that it hid data about the danger.  Interestingly, a full page add in the NY Times this week by DuPont asserts that Teflon is safe.  Teflon is a trademarked polytetrafluroethylene (PTFE) resin related to PFOA. Teflon cookware appears to have residues of PFOA 1/300th that of microwavable popcorn bags.

Broccoli, cabbage, garlic, gingko biloba may prevent cancers.
Some evidence-based medicine types went to a lot of trouble obtaining this graphically-displayed data (see figure 1).

Turmeric shows promise in preventing chronic diseases.
A reviewer of1500 studies of turmeric concluded that this safe food additive can shield us from a host of widespread diseases including heart, cancer, neurodegenerative and eye disorders.  The review appears this month in the Journal of Parenteral and Enteral Nutrition, which is highly respected by top hospital-based nutrition teams.

When it pays to buy organic.
The Environmental Working Group’s review was cited in the February 2006 Consumer Reports.  If you are trying to limit your food shopping bill this link will help you prioritize.  One can click through to the science that supports choosing organic particularly when it comes to the “Dirty Dozen”: apples, peppers, celery, cherries, imported grapes, nectarines, peaches, pears, potatoes, red raspberries, spinach and strawberries.  The link also shows those foods which test low in potentially toxic pesticide residues. The link surpassed my expectations. Explore it. Note that the “Dirty Dozen” are all plant produce and bioaccumulation in animal flesh, especially fat, may be more significant.
