Food Variety

In 80 Years, We Lost 93% Of Variety In Our Food Seeds

IT’S DOWNRIGHT SCARY TO SEE THE LACK OF DIVERSITY IN THE HEALTHIEST FOODS WE EAT.

Seeds are tricky things. On one hand, we have the whole Omnivore’s Dilemma argument, that industrialized and genetically engineered food is probably bad. And on the other, we have strains of vegetables that can grow four times as much produce on the same plot of land as their heirloom counterparts--a successful, man-dictated genetics that we’ve actually been fueling for millennia. After all, we wouldn’t have the heirloom seeds of today if our grandfather’s grandfather’s grandfather hadn’t saved the seeds from the sweetest watermelons or the most drought-resistant cantaloupes.

I don’t know that any of us can honestly assess the repercussions of our actions, but I do know one thing: This National Geographic infographic by John Tomanio is staggering. Using the metaphor of a tree, it charts the loss of U.S. seed variety from 1903 to 1983. And what you see is that we’ve lost about 93% of our unique seed strands behind some of the most popular produce. (Clever details: Where the root system should be strong, Tomanio has rendered a tree that looks like it could tip right out of the ground.)

In 1903, we had almost 500 varieties of lettuce. By 1983, we had just 36. Radishes, peas, and beets have fared no better. In fact, the most steadfast of the crops has been the tomato, which, probably due to the popularity of strange and tasty heirloom varieties, only lost about 80% of its seed diversity. It’s a shame to lose so many intricacies of nature’s tastiest gifts. But more worryingly, monocultures strip the land of nutrients: Where you once had self-sustaining harvest cycles, you get farm land denuded of nutrients that then needs copious chemical fertilizers to grow more food. And the crops themselves become vulnerable to plant diseases.

Still, a lot has changed in the public consciousness since 1983. Farmers markets aren’t just for hippies anymore--they’re lifestyle statements for everyone from young foodies to soccer moms. And as long as this trend stays alive, so too will many of the heirloom seed strands we have remaining.

Mind-altering microbes: Probiotic bacteria may lessen anxiety and depression

Professor John Cryan, Alimentary Pharmabiotic Centre, University College Cork (Credit: Image courtesy of University College Cork) ScienceDaily (Aug. 30, 2011) — Probiotic bacteria have the potential to alter brain neurochemistry and treat anxiety and depression-related disorders according to research published in the Proceedings of the National Academy of Sciences. The research, carried out by Dr Javier Bravo, and Professor John Cryan at the Alimentary Pharmabiotic Centre in University College Cork, along with collaborators from the Brain-Body Institute at McMaster University in Canada, demonstrated that mice fed with Lactobacillus rhamnosus JB-1 showed significantly fewer stress, anxiety and depression-related behaviours than those fed with just broth. Moreover, ingestion of the bacteria resulted in significantly lower levels of the stress-induced hormone, corticosterone. "This study identifies potential brain targets and a pathway through which certain gut organisms can alte

Probiotics Fight Cancer, Colds and Constipation

Image
It may not surprise you to hear that probiotics can reduce constipation (Italy, Amenta et al. 2006). But what may surprise you, is that probiotics play a role in cancer. They have been shown stimulate production of anti-cancer chemicals (Hatakka et al. 2008). The probiotics, Lactobacillus casei, have also been shown in Tokyo to reduce the risk of bladder cancer, depending on frequency and dosage (Ohashi et al. 2002). Numerous probiotics have been shown to fight viruses such as colds, the flu, rotavirus, herpes and ulcers. In New Delhi, 100 children ages 2-5 were given L. acidophilus for 6 months. These children have fewer incidences of colds, flu, diarrhea and fever than the placebo group (Saran et al. 2002). In Japan, Bio E has conducted several studies in hospital in the Philippines & South East Asia that has shown remarkable improvements & shortened days of recovery on children using Bio-15 & Biogenics MD probiotics.

GMO Sweet Corn - Buyers Beware!

Image
Monsanto and the EPA swore that the genetically engineered corn would only harm insects. The Bt-toxin produced inside the plant would be completely destroyed in the human digestive system and would not have any impact at all on consumers, they claimed. Alas, they’ve been proven wrong on that account as well, because not only is Bt corn producing resistant “super-pests,” researchers have also found that the Bt-toxin can indeed wreak havoc on human health. Bt-Toxin Now Found in Many People’s Blood! Last year, doctors at Sherbrooke University Hospital in Quebec found Bt-toxin in the blood of: • 93% of pregnant women tested • 80% of umbilical blood in their babies, and • 67% of non-pregnant women The study authors speculate that the Bt toxin was likely consumed in the normal diet of the Canadian middle class—which makes sense when you consider that genetically engineered corn is present in the vast majority of all processed foods and drinks in the form of high fructose
