Is Your Olive Oil Pure?


Olive oil fraud is making the headlines after new research discovered that it may be the world's most mislabeled, misrepresented and downright impure food on grocery shelves. Worse, you'll recognize some of the brand names caught red-handed in the liquid gold scandal.

Olive oil fraud has been around since Roman times, and sadly, it has never really been controlled. The pr...
oblem: It's difficult and
costly to produce excellent olive oil, but easy to doctor it and rake in the profits. In the late 1990s, the European Union recognized olive oil as its most adulterated food; now, the U.S.

Pharmacopeial Convention has released a food fraud database that shows a similar state of affairs.
Search the USP database for "olive oil," and you'll find all sorts of reported fraud. These generally fall into three types:

Adulteration

Undoubtedly the most criminal type of fraud, and incredibly common. Olive oil is simply mixed, or replaced entirely, with cheaper oils like hazelnut, sunflower, palm and soy. You won't find this information on the label, as many people with food allergies have found out the hard way.

Extra-Virgin Fraud

In a 2010 study at U.C. Davis, 69 percent of imported olive oils and 10 percent of California olive oils failed to meet U.S. standards for "extra virginity." This means they were of low quality, had oxidized, or had been adulterated with cheaper oils. The list of brands that failed may make you weep a little:
  • Whole Foods 365 100% Italian
  • Rachel Ray
  • Safeway Select
  • Newman's Own Organics
  • Colavita
  • Bertolli
  • Filippo Berio
  • Pompeian
  • Star
  • Carapelli
  • Mezzetta
  • Mazzola

Geographic Fraud

Your olive oil may proclaim that it was made in Italy, but it may just have traveled through Italy on its way from... somewhere else. While it's not necessarily true that oil made in Italy is automatically better than that made anywhere else, Italian olive oil commands a higher price. This practice is technically legal, so don't expect it to stop any time soon. Instead, seek out quality oil regardless of the label.

What To Do

Luckily, there's plenty of amazing olive oil in the world — you just need to seek it out. Look for small, independent producers, and in the springtime, buy freshly produced oil to get olives' antioxidant and health benefits. Look for dark glass bottles, and check for a harvest or milling date. If you live in the United States, stick with California-produced oils, which are less likely to be fraudulent. And take the time to train your palate, by tasting olive oils whenever you can. Once you learn the difference between real and fake, and get a feel for what you like best about olive oil, you'll never go back to the questionable stuff.
Sadly, olive oil isn't alone on the fraud list. Milk, honey, saffron, orange juice, coffee and apple juice are also foods to watch out for, so shop smart!

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

Image
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
