Science And Nature, Working Together

People who live on vegetarian diets have weaker bones than their meat-eating counterparts, said Australian researchers. See you wussies, more proof that you can't beat meat. You can beat your own, but that's another story...

A joint Australian-Vietnamese study of links between the bones and diet of more than 2,700 people found that vegetarians had bones 5% less dense than meat-eaters. The issue was more pronounced in vegans, who excluded all animal products from their diet and whose bones were 6% weaker. There was "practically no difference" between the bones of meat-eaters and ovolactovegetarians, who excluded meat and seafood but ate eggs and dairy products, their study discovered. Hey wait - you're saying dairy and eggs are are practically a substitute for meat?

"The results suggest that vegetarian diets, particularly vegan diets, are associated with lower bone mineral density," according to the published results in the American Journal of Clinical Nutrition. "But the magnitude of the association is clinically insignificant," it added. So, you're saying that your findings and the study don't amount to anything important? "Given the rising number of vegetarians, roughly 5% (of people) in western countries, and the widespread incidence of osteoporosis, the issue is worth resolving.". Damn it, is it or is it not a big deal?

That may not make a difference, since tomato plants have been removed from stores in half a dozen states as a destructive and infectious plant disease makes its earliest and most widespread appearance ever in the eastern United States!

Late blight — the same disease that caused the Irish Potato Famine in the 1840s — occurs sporadically in the Northeast, but this year's outbreak is more severe for two reasons: infected plants have been widely distributed by big-box retail stores and rainy weather has hastened the spores' airborne spread. The disease, which is not harmful to humans, is extremely contagious and experts say it most likely spread on garden center shelves to plants not involved in the initial infection. It also can spread once plants reach their final destination, putting tomato and potato plants in both home gardens and commercial fields at risk. Sounds like a good time to save your bone density and eat meat!

Meg McGrath, professor of plant pathology at Cornell University - yes, apparently that is a real job, calls late blight "worse than the Bubonic Plague for plants." She adds in this once in a career moment, "People need to realize this is probably one of the worst diseases we have in the vegetable world...It's certain death for a tomato plant."

Tomato plants have been removed from Home Depot, Wal-Mart, Lowe's and Kmart stores in all six New England states, plus New York. Late blight also has been identified in all other East Coast states except Georgia, as well as Alabama, West Virginia and Ohio. It is too early in the season to know whether infected plants will taint large crops or negatively affect commercial growers. But if that happens, growers could be forced to raise prices to cover costs associated with combating the disease.

Agriculture officials in the various states still are trying to determine where the outbreak started. One major grower who supplies most of the tomato plants to big-box stores, has regularly inspected greenhouses in 38 states, and found no evidence of disease most recently. In the meantime, plant experts are warning gardeners to be on the lookout for the disease and to take quick action if it crops up. The first sign is often brown spots on plant stems, followed by nickel-sized olive-green or brown spots on the tops of leaves and fuzzy white fungal growth underneath. Tomato fruit will show firm, brown spots. Spraying with fungicides can control late blight if begun before symptoms appear, but many plant experts recommend removing and destroying the plants instead to prevent spores from traveling. I suggest a hearty treatment...of meat!
