Kale, collard and mustard greens, as well as hot peppers and bell peppers, had the most pesticides detected, 103 and 101 pesticides in total, respectively. A single sample of kale, collard and mustard greens had up to 21 different pesticides.
Strawberries and spinach continue to top the annual list of the “Dirty Dozen” fruits and veggies that contain the highest levels of pesticides, followed by three greens – kale, collard and mustard – nectarines, apples, grapes, and bell and hot peppers, according to the Environmental Working Group's 2022 Shopper's Guide ...
However, there is one vegetable that can be partially poisonous to humans: rhubarb leaves. Rhubarb leaves contain oxalic acid, a chemical that can cause death if a human consumes between 5.7 and 11.7 pounds of rhubarb leaves, depending on the specific leaves and the individual's weight, according to Healthline.
Strawberries, Raspberries and Cherries Strawberries are the crop that is most heavily dosed with pesticides in America. On average, 300 pounds of pesticides are applied to every acre of strawberries (compared to an average of 25 pounds per acre for other foods).
As a rule of thumb, washing with water reduces dirt, germs, and pesticide residues remaining on fresh fruit and vegetable surfaces. Washing and rubbing produce under running water is better than dunking it. Wash fruits and vegetables from the farmers' market, your home garden, and the grocery store.
Once again, strawberries, spinach and leafy greens (like kale and collards) are the top offenders. Nectarines, apples and grapes follow, with bell peppers, cherries, peaches, pears, celery and tomatoes stacking on.
Testing of produce sold in the US shows that the Clean Fifteen — including avocado, cabbage, onion, mango, kiwi and broccoli — often contain little or no detectable pesticide residues. Additionally, these residues are well within EPA limits.
1. Spinach. This leafy green tops the chart as one of the most nutrient-dense vegetables. That's because 1 cup (30 grams) of raw spinach provides 16% of the Daily Value (DV) for vitamin A plus 120% of the DV for vitamin K — all for just 7 calories ( 1 ).
Conventional bananas are sprayed with synthetic fertilizers, insecticides, and herbicides. Yes, this is just as bad as it sounds—but not just for you. The workers on many conventional plantations are often exposed to these toxins. This leads to a host of health conditions including skin diseases and kidney failure.
Cabbage and Its Cousins
Cruciferous vegetables, like broccoli and cabbage, have the same sugars that make beans gassy. Their high fiber can also make them hard to digest. It will be easier on your stomach if you cook them instead of eating raw.
Nightshade vegetables, like peppers, potatoes, and eggplant, are are controversial, because many claim they can cause inflammation, according to Cynthia Sass, a registered dietician. This can lead to some pretty serious complications down the line: heart disease, cancer, and diabetes, to name a few.
Sustainability of Blueberries
Unfortunately, domestic blueberries rank a fairly high 16 on the Environmental Working Group's Guide to Pesticides in Produce, a list EWG created to single out produce with the highest loads of pesticide residues. (Here's a list of pesticides commonly found on blueberries.)
Washing with 2% of salt water will remove most of the contact pesticide residues that normally appear on the surface of the vegetables and fruits. About 75-80% of pesticide reduces are removed by cold water washing.
Worst Veggie: Starchy Vegetables
Corn, peas, potatoes, pumpkin, squash, and yams are starchy vegetables. However, not all starch vegetables offer the same nutritional benefits.
1. Spinach And Other Leafy Greens. Spinach and other leafy green vegetables like kale, lettuce, etc. are great for burning belly fat and are very nutritious as well.
Carrots, for example, are well known for their ability to absorb pesticide residues from soils. One study found that concentrations of pesticides in carrots could be as high as 80% of the concentration in the soil, with up to 50% of that concentration contained in the pulp (rather than the peel) of the carrot.
For yard long beans, pesticide residues were reduced by 38–100% after boiling, 27–28% after blanching, and 35–63% after stir-frying. Therefore, cooking vegetables are proven to protect consumers from ingesting pesticide residues.
Produce with irregular surfaces, such as broccoli, should be soaked in cold water for 1-2 minutes to remove impurities from the crevasses. Don't use soap, special washes or bleach to wash produce—these could leave residue behind.
First, conventional coffee is among the most heavily chemically treated foods in the world. It is steeped in synthetic fertilizers, pesticides, herbicides, fungicides, and insecticides – a real mouthful with a bad taste. Not only does the environment suffer from this overload, but so do the people who live in it.
The most effective way to clean pesticide residue off of strawberries is to submerge them in a vinegar bath. In a bowl, mix four parts water with one part white vinegar, then let the strawberries soak in the bowl for 20 minutes. Rinse the strawberries thoroughly with fresh cold water to clean off the vinegar.
