Avoiding the dirty dozen – those fruits and vegetables most contaminated with pesticides

Environmental Working Group has released the seventh edition of its Shopper’s Guide to Pesticides in Produce with updated information on 53 fruits and vegetables and their total pesticide loads.  EWG highlights the worst offenders with its “Dirty Dozen” list and the cleanest conventional produce with its “Clean 15” list.

Analysts at EWG synthesized data collected from the U.S. Department of Agriculture and the Food and Drug Administration from 2000 to 2009.  Produce is ranked based on a composite score, equally weighing six factors that reflect how many pesticides was found in testing of on each type of the produce and at what levels.  Most samples are washed and peeled prior to being tested, so the rankings reflect the amounts of the chemicals likely present on the food when is it eaten.

Notable changes in the new guide included apples’ rank as the most contaminated produce, jumping three spots from last year to replace celery at the top of the “Dirty Dozen” list.  According to USDA, pesticides showed up on 98 percent of the more than 700 apple samples tested.

1 Apple Apples
2 Celery Celery
3 Strawberries Strawberries
4 Peaches Peaches
5 Spinach Spinach
6 Nectarines Nectarines  – imported
7 Grapes Grapes – imported
8 Red Pepper Sweet bell peppers
9 Potatoe Potatoes
10 BlueberriesBlueberries  – domestic
11 Lettuce Lettuce
12 KaleKale/collard greens

Making an appearance in the guide for the first time is the herb cilantro, which had never been tested by USDA until now.  The data showed 33 unapproved pesticides on 44 percent of the cilantro samples tested, which is the highest percentage of unapproved pesticides recorded on any item included in the guide since EWG started tracking the data in 1995.

Also appearing in the guide for the first time are green onions, cranberries and mushrooms.  Mushrooms made the “Clean 15” list, while honeydew was the only item to drop off that list this year.  Cherries dropped off the “Dirty Dozen” list, but lettuce, which has made the list in previous years, were back on.

“Though buying organic is always the best choice, we know that sometimes people do not have access to that produce or cannot afford it,” said EWG President Ken Cook.  “Our guide helps consumers concerned about pesticides to make better choices among conventional produce, and lets them know which fruits and vegetables they may want to buy organic.”

Pesticides can be extremely toxic to human health and the environment. U.S. and international government agencies alike have linked pesticides to nervous system toxicity, cancer, hormone system disruption and IQ deficits among children.

“I really worry that pesticides on food are unhealthy for the tender, developing brains and bodies of young children,” said Dr. Harvey Karp, MD, FAAP, creator of the book/DVD The Happiest Baby on the Block.  ”Parents don’t realize they’re often feeding their little ones fruits and veggies with the highest pesticide residues.  Studies show even small amounts of these chemicals add up and can impair a child’s health when they’re exposed during the early, critical stages of their development.  When pesticide sprayers have to bundle up in astronaut-like suits for protection, it’s clear parents want to feed their families food containing as little of these toxic chemicals as possible.”

“Pesticides, while designed specifically to kill certain organisms, are also associated with a host of very serious health problems in people, including neurological deficits, ADHD, endocrine system disruption and cancer,” said Andrew Weil, MD, Founder and Director, Arizona Center for Integrative Medicine and a renowned medical expert on natural health and wellness. “My advice to consumers is to whenever possible avoid exposure to pesticides, including pesticide residues on food.”

Consumers who choose five servings of fruits and vegetables a day from EWG’s Clean 15 list rather than from the Dirty Dozen can lower the volume of pesticides they consume by 92 percent, according to EWG’s calculations.  They will also eat fewer types of pesticides. Picking five servings of fruits and vegetables from the 12 most-contaminated products would result in consuming an average of 14 different pesticides a day.  Choosing five servings from the 15 least contaminated fruits and vegetables would result in consuming fewer than two pesticides per day.

The health benefits of a diet rich in fruits and vegetables outweigh the risks of pesticide exposure, and EWG strongly recommends that everyone follow USDA’s recommendation to eat five servings of fruits and vegetables every day. The Shopper’s Guide makes it easy to meet that goal while reducing your exposure to pesticides.

Is chocolate good for your heart?

I can’t get enough of John Robbin’s blog lately. If you’ve never heard the name, his father is one half of the famous Baskin-Robbins ice cream empire. He turned down the opportunity to follow in his father’s footsteps, instead taking off to a tiny island with his wife, where they grew 90% of their food for ten years. I have some of his many books on my Amazon wishlist right now, but for now the blog is a wealth of interesting reading.

This post highlights some of the many health benfits of my favourite indulgence. So grab yourself a small bar of dark, fairtrade, organic choclate and enjoy!

Chocolate’s Startling Health Benefits

March 16th, 2011

The food police may find this hard to take, but chocolate has gotten a bad rap. People say it causes acne, that you should eat carob instead, that it’s junk food. But these accusations are not only undeserved and inaccurate, they falsely incriminate a delicious food that turns out to have profoundly important healing powers.

There is in fact a growing body of credible scientific evidence that chocolate contains a host of heart-healthy and mood-enhancing phytochemicals, with benefits to both body and mind.

For one, chocolate is a plentiful source of antioxidants. These are substances that reduce the ongoing cellular and arterial damage caused by oxidative reactions.

You may have heard of a type of antioxidants called polyphenols. These are protective chemicals found in plant foods such as red wine and green tea. Chocolate, it turns out, is particularly rich in polyphenols. According to researchers at the University of Texas Southwestern Medical Center in Dallas, the same antioxidant properties found in red wine that protect against heart disease are also found in comparable quantities in chocolate.

How does chocolate help to prevent heart disease? The oxidation of LDL cholesterol is considered a major factor in the promotion of coronary disease. When this waxy substance oxidizes, it tends to stick to artery walls, increasing the risk of a heart attack or stroke. But chocolate to the rescue! The polyphenols in chocolate inhibit oxidation of LDL cholesterol.

And there’s more. One of the causes of atherosclerosis is blood platelets clumping together, a process called aggregation. The polyphenols in chocolate inhibit this clumping, reducing the risks of atherosclerosis.

High blood pressure is a well known risk factor for heart disease. It is also one of the most common causes of kidney failure, and a significant contributor to many kinds of dementia and cognitive impairment. Studies have shown that consuming a small bar of dark chocolate daily can reduce blood pressure in people with mild hypertension.

Why are people with risk factors for heart disease sometimes told to take a baby aspirin every day? The reason is that aspirin thins the blood and reduces the likelihood of clots forming (clots play a key role in many heart attacks and strokes). Research performed at the department of nutrition at the University of California, Davis, found that chocolate thins the blood and performs the same anti-clotting activity as aspirin. “Our work supports the concept that the chronic consumption of cocoa may be associated with improved cardiovascular health,” said UC Davis researcher Carl Keen.

How much chocolate would you have to eat to obtain these benefits? Less than you might think. According to a study published in the American Journal of Clinical Nutrition, adding only half an ounce of dark chocolate to an average American diet is enough to increase total antioxidant capacity 4 percent, and lessen oxidation of LDL cholesterol.

Why, then, has chocolate gotten such a bum reputation? It’s the ingredients we add to it. Nearly all of the calories in a typical chocolate bar are sugar and fat.

As far as fats go, it’s the added fats that are the difficulty, not the natural fat (called cocoa butter) found in chocolate. Cocoa butter is high in saturated fat, so many people assume that it’s not good for your cardiovascular system. But most of the saturated fat content in cocoa butter is stearic acid, which numerous studies have shown does not raise blood cholesterol levels. In the human body, it acts much like the monounsaturated fat in olive oil.

Milk chocolate, on the other hand, contains added butterfat which can raise blood cholesterol levels. And it has less antioxidants and other beneficial phytochemicals than dark chocolate.

Does chocolate contribute to acne? Milk chocolate has been shown to do so, but I’ve never heard of any evidence incriminating dark chocolate.

Dark chocolate is also healthier because it has less added sugar. I’m sure you don’t need another lecture on the dangers of excess sugar consumption. But if you want to become obese and dramatically raise your odds of developing diabetes, heart disease, cancer and Alzheimer’s disease, foods high in sugar (including high fructose corn syrup) are just the ticket.

Are chocolate’s benefits limited to the health of the body? Hardly. Chocolate has long been renown for its remarkable effects on human mood. We are now beginning to understand why.

Chocolate is the richest known source of a little-known substance called theobromine, a close chemical relative of caffeine. Theobromine, like caffeine, and also like the asthma drug theophylline, belong to the chemical group known as xanthine alkaloids. Chocolate products contain small amounts of caffeine, but not nearly enough to explain the attractions, fascinations, addictions, and effects of chocolate. The mood enhancement produced by chocolate may be primarily due to theobromine.

Chocolate also contains other substances with mood elevating effects. One is phenethylamine, which triggers the release of pleasurable endorphins and potentates the action of dopamine, a neurochemical associated with sexual arousal and pleasure. Phenethylamine is released in the brain when people become infatuated or fall in love.

Another substance found in chocolate is anandamide (from the Sanskrit word “ananda,” which means peaceful bliss). A fatty substance that is naturally produced in the brain, anandamide has been isolated from chocolate by pharmacologists at the Neurosciences Institute in San Diego. It binds to the same receptor sites in the brain as cannabinoids — the psychoactive constituents in marijuana — and produces feelings of elation and exhilaration. (If this becomes more widely known, will they make chocolate illegal?)

If that weren’t enough, chocolate also boosts brain levels of serotonin. Women typically have lower serotonin levels during PMS and menstruation, which may be one reason women typically experience stronger cravings for chocolate at these times in their cycles. People suffering from depression so characteristically have lower serotonin levels that an entire class of anti-depressive medications called serotonin uptake inhibitors (including Prozac, Paxil, and Zooloft) have been developed that raise brain levels of serotonin.

Since I am known as an advocate of healthy eating, I’m often asked about my food indulgences. One of my favorite desserts is a piece of dark organic chocolate, along with a glass of a fine red wine.

I do have a policy, though, to eat only organic and/or fair trade chocolate. This is because of what I have learned about child slavery in the cocoa trade.

May your life be full of healthy pleasures.
