Recently by Mark Sisson: I Have Never Felt Better in My Life
A couple weeks ago, I gave you a list of the top 10 foods you should strive to buy organic. Some of you found the list useful, while others felt a bit overwhelmed and disheartened by the information, saying that it felt like they couldn’t eat anything that wasn’t organic. Today, I’ll try to make things a little better by giving you a list of the foods which are perfectly fine in their conventional form. However, even if the following conventional foods are relatively safe for your health, some would argue that you should still buy organic in order to support the workers and protect the environments exposed to agricultural chemicals. That’s totally valid, and it’s part of the reason why I try to buy organic, but it’s not what I’m discussing here. It’s a topic for another time. Today is about maximizing the health of you and your family while cutting costs when and where you can.
So, what common, Primal staples can you buy conventional?
You won’t see coconut on any Clean 15 or Dirty Dozen lists anytime soon, because the general public has yet to catch on to its fatty, nutty delights. That said, we Primal people eat coconut. We saut with coconut oil and slather it onto vegetables, sweet potatoes, hair, skin, and armpits. We drink and make curries with coconut milk and cream. We obsess over coconut butter, paying tribute to its glory with a greasy spoon. And when we’ve been running or training particularly hard — or it’s hot out — we often reach for the coconut water. We like our coconut, so it’s in our best interest to determine whether we should be buying organic or not.
Luckily for us, it doesn’t look like organic coconut makes a big difference. Several studies have looked for pesticide residues in coconut products and come up virtually empty handed. There’s this 2008 study, which was unable to detect any pesticide residues in crude coconut oil. Poly-aromatic hydrocarbons, which are generated during the coconut flesh quick drying process and are carcinogenic, were detected in crude coconut oil but were removed in the refining process. Virgin unrefined coconut oil, then, may still contain these hydrocarbons, unless it’s wet-milled and processed without quick-drying the flesh. That goes for both organic and conventional coconut oil, to be clear.
In another study, researchers examined 15 samples of coconut water using two different methods of pesticide detection and were unable to detect any of the 11 pesticides they were looking for.
Coconut milk is also going to be as free from pesticides as any other coconut product. Since it’s made from fresh flesh, not the dried, heat-treated stuff, coconut milk should also be free of poly-aromatic hydrocarbons.
Onions don’t just make you cry for cutting them, they make pests weep at the thought of eating them. Onions are naturally resistant to pests, which is probably why just 0.3% of onions tested for chemical residue came up positive. Big Agra may cut corners and prioritize profit over quality or consumer health, but that just means they won’t fork out the money for chemicals if they don’t have to; they’re not comic book villains, dumping drums of noxious endocrine disruptors and carcinogens onto their crops to punish us. Not onion farmers, at least.
So, feel free to go wild with conventional onions, because there is very little, if any, advantage to organic onions from a health perspective. Unlike many other fruits and vegetables, conventionally grown onions have the same level of polyphenols as organically grown onions.
Avocados are another safe food that ends up with some of the lowest pesticide residues around. Maybe it’s the scaly skin and the way they just kinda “lurk” there up in tree tricking pests into thinking they’re up against alligators. Maybe it’s the fact that a bug got burned one too many times with a beautiful looking avocado that turned out to be stringy and brown on the inside. Maybe pests just hate waiting for an avocado to ripen (who doesn’t?) and give up. Actually, even though a somewhat significant amount of chemicals can be used on avocado orchards, they just don’t make it into the fatty, delicious flesh we crave and consume.
Avocado farmers, both organic and conventional, do use extensive amounts of copper as a fungicide. Copper is an essential nutrient, but too much can be harmful. A single Florida avocado contains 0.9 mg, which is about 100% of the RDI, so don’t go around eating several a day.
