Organic Foods

Via Mike, an excellent article explaining why organic foods might not be as healthy as you thought.

Toxicologist Bruce Ames of the University of California became famous in the 1970s for sounding the alarm on the cancer-causing (or carcinogenic) potential of man-made chemicals.

But after testing 'natural' pesticides in rats, he called off the warning. A paper he published in 1990 said it all. Entitled, "Dietary Pesticides (99.99 per cent All Natural)", it reported that in a regular diet, people consume about 10,000 times more natural carcinogens than synthetic ones.

Hey, but "natural" carcinogens give you safer, more Gaia-friendly kinds of cancer, right?

Comments

Interesting article, and it made some good points. I'm all for using the best techniques available for a job, though I remain skeptical and cautious because of our proven tendency to overuse and abuse and to think in isolation. As an example of the last, think of enriched white flour. We strip goodness from the wheat and think we've restored it by adding back a few, isolated vitamins.

I'm also old enough to recognize that our modern agricultural methods have made an enormous amount of food, in great variety, available at unbelievably low prices, so I temper my enthusiasm for more natural methods with concern for those who would gladly have even poor-quality food to alleviate their hunger.

Although I'm not qualified to say much about pesticides, fertilizers, or nutrition, I do know one thing missing from our mass-produced foods: flavor. The classic example is the home-grown tomato. My daughter said it best when she was little: "A store-bought tomato is a vegetable; a home-grown tomato is a fruit!" If you've ever had the privilege of tasting unpasteurized cider at a small New England orchard, or unpasteurized milk from a cow raised on pasture, or unpasteurized orange or grapefruit juice directly from the grove, you know how little these wonders resemble the products of the same name you can buy in the grocery store. There's a great variety in the taste of oranges -- why should cartons of orange juice all have the same, bland flavor?

I'm not against agri-businesses; they have their place. I'm not convinced they need government subsidies, however! Let those go to small, independent farmers -- organic and otherwise -- who are preserving a national treasure.

(interesing article, Tim)

SursumCorda - There's a great variety in the taste of oranges -- why should cartons of orange juice all have the same, bland flavor?

Adding to Michael's answer...

The quality of citrus is determined by the ratio between sugar content and acidity. source
" For processed fruits, growers are paid for "pounds solids" or the quantity of sugar in a load of fruits..." source


I would guess that effectively judging the quality of mass produced fruit juice is a problem similar to the one that organic farming seems to be running into; What kind of standard do you use to mass produce and standardize quality? Especially, how do you find one simple enough that people can actually use it. Could a better standard create an incentive for better tasting, mass produced juice?

I'm a big fan of food irradiation, which was mentioned in the article. The harm caused by molds and the antifungal agents used to control them could be dramatically reduced by food irradiation. The biggest drawback to irradiation (outside of the PR aspects) is the slight increase in free radical content of foods (which also occurs with cooking.) While I have mixed feelings about any technology that increases a vegetable's shelf life (because it will be used for that purpose, giving us less fresh foods) the tech is pretty amazing.

Ryan, I'm glad you brought up the "from concentrate" juice, because that's what I use to try to explain the taste of "real" citrus juices to those who've never tasted them. As high as "fresh, not from concentrate" juice is above the reconstituted variety, so is unpasteurized juice above the best "not from concentrate." And the fact that you specify "pure valencia" illustrates the other problem: Valencia is but one variety of orange, albeit popular for juicing. Wine is not all the same flavor -- neither should orange juice be. I'm speaking of citrus juice because that's what I know best, but I feel the same way about cider/apple juice, and milk as well.

Certainly bland, all-the-same orange juice is what people buy, because that's what they find on their grocer's shelves. And it's true that what is available has improved greatly since the days of concentrate-only.

But it's not true that the good stuff can't be sold in grocery stores. When I can't get to a grove (which, sad to say, is usually the case), I can buy fresh, unpasteurized juice at Whole Foods or at The Fresh Market; I've also found it available in the Northeast at Wegmans supermarkets.

I don't think regulation should be an issue. Here in Florida, producers who follow a rigorous procedure of cleanliness (which, frankly, I'd want anyway) are licensed by the state to sell unpasteurized juice. In Connecticut the same is true for selling unpasteurized milk.

Mind you, it's not cheap. I usually pay $5/half gallon for my unpasteurized grapefruit juice, because the closer source is the more expensive. But to anyone who says he doesn't like grapefruit juice, I say that if you haven't tried the real thing, you haven't tried grapefruit juice.
