Bottom Line Personal, in its August 15, 2010 issue, reports on a recent study that found that bacteria thrive in reusable shopping bags.
Bacterial growth was found on 50% of the bags; 12% contained E. coli bacteria.
Charles P. Gerba, a professor of soil, water, and environmental science at the University of Arizona in Tucson, led the study.
The main lesson:
Wash reusable bags regularly with soap and water.

Plastic containers - which are safe and unsafe?
Plastic containers have a number stamped on the bottom - from 1-7.
I keep a note on my refrigerator listing which are safe and unsafe.
The online information is somewhat inconsistent, but this is what most sources say:
#1 is apparently ok but only for single use. Some sources recommend avoiding it entirely.
#2 is good.
#4 and 5 are ok.
#3, 6, and 7 are NOT safe.
Never microwave any of these.

Dietary Supplements: Warnings and Recommendations
Consumer Reports has an article in their latest issue, September 2010, called Dangerous Supplements. Since they almost always do a fine job of evaluating products, I was interested.
A bit of history concerning this interest of mine. I had been disturbed by what looked like too much unnecessary regulation of over the counter products. I had started taking red yeast rice at the recommendation of my primary care provider as an alternative to taking a prescription statin drug to lower my cholesterol. Her patients had had success with this product with fewer side effects than with prescription statin drugs.
After purchasing it online and being on it for a few months, my cholesterol dropped and was in the normal range for the first time in many years. I was delighted as was my PCP. Then, at the next blood check, my cholesterol started going back up. After some checking, we concluded that it was probably because the company manufacturing the red yeast rice had been forced to remove its effective statin-like ingredient. It seemed to me at the time that this was about profits and control rather than safety, and I was not at all happy, especially since I was being monitored closely to make sure there were no problems.
In a case like this, it is easy to have a knee-jerk reaction of anger, not look at all sides of the question, and generalize from one experience. Consumer Reports points out that there are products that have caused damage and require regulation.
As for the article, it looks at both dangerous supplements and at other supplements worth considering.
First comes the list of the dangerous ‘dirty dozen’: Aconite, Bitter Orange, Chaparral, Colloidal Silver, Coltsfoot, Comfrey, Country Mallow, Germanium, Greater Celandine, Kava, Lobelia, and Yohimbe. In the magazine, there is a chart that gives more detail about the uses, dangers, and other comments about each.
Next are their supplements to consider. These have apparently been shown to likely be safe for most people and possibly or likely to be effective for certain conditions.
Calcium, Cranberry, Fish Oil, Glucosamine Sulfate, Lactase, Lactobacillus, Psyllium, Pygeum, SAM-e, St. John’s Wort, and Vitamin D. Again, the article gives more details about each of these supplements.
I plan to to print the names of both on an index card to keep on hand while browsing through vitamin catalogs or at the drug store when considering a purchase.
Also rated in the article were multivitamins. They found most of the products to be of decent quality and to contain the ingredients in the amounts stated on the containers. They were also found to dissolve properly so that they could be absorbed into the system. The overriding message, however, was that most people do not need or benefit from multivitamins unless they are suffering from severe nutritional deficiencies. The irony is that it may look like there are benefits to taking them because the very people who are healthiest are often the ones who take them. It is easy to see how this would skew study results.
One thing I have learned is that all of this information needs regular revisiting and reevaluation. We can only work with our best current information and then be willing to discard it when new and solid research comes to the fore. And rather than jumping at every news item that touts another miracle product, there needs to be time for sifting and evaluating carefully with the help of sources such as CR and others.
