In the EU, meat cannot be treated with carbon monoxide to preserve a look of freshness, so food scientists have had to look for other methods of keeping packaged meat looking pink and appealing to consumers. Spanish researchers recently hit upon a possible solution: rosemary. Their studies show that a rosemary extract added to the packaging will have the same effect as carbon monoxide treatment. This so-called "active packaging" could be the wave of the future as far as meat products are concerned, since beef steaks packed in the "rosemary-enhanced plastic film" remained fresh-looking for 14 days under supermarket conditions - an increase of two days over chemical preservation.

The downside might be for consumers, who could have difficulty discerning the difference between a 2-day-old steak and a 2-week old one, although the idea of getting chemically-treated meat off the shelves sounds like one that most meat-eaters could get behind anyway.

No additives, no hormones. no chemicals... do these phrases mean what you think they mean? The Diet Detective has a little guide to help you figure out what these designations mean, and it isn't always what you think.

• No antibiotics - Some antibiotics are given to treat sick animals, and given to the whole herd when one animal is ill. The "subtheraputic" use of drugs to boost animal growth is the main concern here, and labeling usually differentiates between the two. Organic farmers cannot use any animal for organic products that has been treated with antibiotics, so they are simple separated from the herd if they must be treated.
• No chemicals - This label means nothing (or anything at all), since there is no USDA or FDA definition of the term.
• No additives - There are 2,800 potential additives for meat in the US and the labeling applies to what was added to the meat, such as colorings and flavorings - not what was fed to the animal in the first place.
• No hormones - Hormones are not allowed in the production of pork and poultry. Period. Cows can be given hormones to speed their growth, though, so if the label specifies that "No hormones [were] administered," the cow probably lived a healthy and natural life.

The Detective notes that because the regulations are in place, doesn't mean that they are always followed. In many cases, there is little in the way of follow-up to prove that all producers are living up to their labels. Many suppliers, however, do live up to the standards set by law, if not to a higher standard of their own. Labeling may not be fail-safe, but it's still more reliable than the alternatives of no labels or completely unsanctioned ones.

Some of you may already be hip to this little trick. My father showed it to me as a young boy and, honestly, I'd sort of forgotten about it until, during a recent visit home, I came across a folded package of Land O'Lakes and realized that Dad must be passing the wisdom on to my younger brother.

For those unaware, the deal is that if you make a little flap out of the package of butter that the Native American woman is holding and then fold under the other image of the girl just so, her knees will appear in the flap and, well, you get the idea.
