The Most Contaminated Foods You Can Buy at the Grocery Store

Tomatoes – especially cooked or canned tomatoes, including juice and sauce – are high in the carotenoid lycopene, which multiple lab studies have shown is capable of inhibiting the growth of cancerous cells and tumors. About 17% of tomatoes tested, however, contain traces of the pesticide Endosulfan II, a suspected hormone disruptor.

Celery is a negative-calorie food, which means that the body spends more calories breaking celery down than it takes from the vegetable itself, resulting in an average loss of calories. Virtually all commercially grown celery, though, contains the pesticides Chlorantraniliprole and Spinosad, the latter of which is a known bee toxin.

Pears are known to be good for the digestive system and have anti-inflammatory properties. they may also boost heart health and lower the risk of diabetes. The down side? Some 40% of them have been found to contain Pyrimethanil, a possible carcinogen with suspected toxicity.

Besides being a delicious summertime treat, peaches are full of vitamins and minerals, including a healthy dose of vitamin C and antioxidant polyphenols and carotenoids. They may, however, contain the bee toxins Fludioxonil and Phosmet as well as iprodione, a known carcinogen.

Cherries are full of vitamins and minerals, and are a good source of potassium, essential for heart health. Among the pesticides they might contain, though, are Bifenthrin, known as a bee toxin and also a developmental or reproductive toxin.

Bell peppers are high in vitamins and antioxidants, especially vitamin C and carotenoids. Some of their health benefits include improving eye health and reducing the risk of some chronic diseases. Both may contain trace amounts and sometimes significant doses of countless pesticides with deleterious effects on humans.

Grapes are a great source of the antioxidant resveratrol, which some studies suggest may help prevent certain cancers including breast, liver, stomach, and lymphatic cancers. One of the main pesticides grapes contain is Imidacloprid, a strong bee toxin.

Apples – particularly their skin – contain a high concentration of the flavonoid quercetin, which has been studied extensively and is shown to inhibit the proliferation of multiple types of cancer including prostate, breast, lung, cervical, and colon. An apple a day may keep the doctor away, but apple-lovers should be aware that the fruit typically contains numerous pesticides, including Diphenylamine or DPA (which has no known toxicity), Thiabendazole (which may be carcinogenic and contain developmental or reproductive toxins), and Pyrimethanil (suspected of being carcinogenic).

Nectarines are rich in vitamin C, vitamin A, and fiber, among other nutrients. The fruit may help with boosting immunity and lowering blood pressure. The main villain here is formetanate hydrochloride, a neurotoxin.

Carotenoids in leafy greens like kale can also boost the body’s antioxidant defenses, helping to prevent cell damage and inhibit the formation of carcinogens. At the same time, ironically, about half the samples tested contained a suspected carcinogen, Dimethyl tetrachloroterephthalate, or DCPA.

Spinach is high in antioxidant carotenoids including lutein and zeaxanthin that could help protect against cancer of the esophagus, stomach, and mouth. The pesticide known as Permethrin, total was found on about 50% of the samples tested; this is a possible carcinogen, a slight bee toxin, and a suspected hormone disrupter.

Strawberries are high in both vitamin C and ellagic acid, which can help prevent cancers of the skin, lung, breast, esophagus, and bladder. Wash them well, though, as they may contain various quantities of almost 50 pesticides.
