16 Foods You Don't Always Need to Buy Organic

It seems like every week a new study or article is published touting the benefits of going organic -- it's better for our health and our environment. But going organic comes at a cost and it's not one everyone can afford, or even has access to. So where do you compromise? Read on to find out which foods are less likely to contain a significant amount of pesticide residue, and are therefore safest to purchase as conventional (i.e. non-organic), if needed.

1. Onions

There's no need to cry over commercially grown onions from a pesticide standpoint. Onions are significantly lower in pesticide residue than other commercial produce, according to the Environmental Working Group, the leading environmental health research and advocacy organization in the U.S. In addition to enhancing the flavor of dishes, onions provide rich amounts of antioxidants. Onions also have a flavonoid called quercetin, which may help inhibit the growth of H. pylori bacteria, which underlies most stomach ulcers. Eat onions fresh on sandwiches, burgers and salads, or as part of a nutritious base for soups, sauces and stir-fries.

2. Avocados

Avocados are the cleanest fruit -- who knew? The Environmental Working Group tested more 3,000 pieces of produce for agricultural chemical residues only one percent of avocado samples showed any detectable pesticides. This is good news because they're loaded with essential nutrients including potassium, folate and vitamins K, B-6, E and C. Avocados are also popular for their healthy fats. So go head and add them to your smoothies for creaminess, sandwiches in place of cheese or just enjoy fresh on a salad.

3. Pineapple

The thick skin of pineapples absorbs most of the pesticides used for cultivation, making it one of the Environmental Working Group's "Clean 15" -- 15 fruits and vegetables with the least pesticide residue. In fact, 89 percent of the pineapples tested had no resides. This is good news because they're loaded with vitamin-C-and they also contain an enzyme called bromelain which helps our bodies breakd down food and reduce inflammation, the root of many chronic diseases. Hoping to save time? Choose unsweetened frozen pineapple, which is as nutritious as fresh.

4. Asparagus

Asparagus is among the vegetables least likely to contain pesticide residue, according to Environmental Working Group analyses. Asparagus provides rich amounts of the flavonoid rutin -- a powerful antioxidant and anti-inflammatory agent. "Asparagus on the grill is a simple and delicious way to enjoy it," said Dina Aronson, a registered dietitian and president of Welltech Solutions in Montclair, New Jersey. "Try it in place of french fries, dipped in a little garlic aioli or even some creamy hummus." Brush trimmed asparagus spears with olive oil, she suggested, then grill them until tender.

5. Grapefruit

Another reason having "thick skin" is a good thing. Thanks to the grapefruit’s dense peel, pesticides are kept from invading the juicy fruit. And they're also weight-friendly making them a win-win. A 2011 study found that when grapefruit or 100% grapefruit juice was consumed 20 minutes before a meals, participants ate about 30 percent less in total calories. That's huge.

Mangos can help satisfy your sweet tooth without excessive calories or pesticides. Like their friend the grapefruit, their dense peel protects their insides from toxic chemicals used for production. One cup of mango has just 100 calories and it stocked with vitamin A and fiber. Serve mango fresh or pureed with ice and other desired fruits as a tasty, nutritious smoothie. For a healthy dessert, top a bowl of fresh mango cubes with a dollop of Greek yogurt.

If you're given the choice between a non-organic nectarine, peach or kiwi, you may want to opt for the kiwi. While nectarines and peaches fall within the Environmental Working Group's top 10 highest pesticide culprits, kiwis fall in the top 10 most "clean." Though kiwis have a thin skin, the fruit is seldom sprayed with pesticides. The rich fiber helps move things along and keeps your appetite in check.

8. Mushrooms

Mushrooms are some of the least pesticide-ridden veggies. They're also nutrient powerhouses, according to a Leslie K. Kay, a clinical dietitian. And the darker the mushroom, the more flavorful, says Kay, who suggests sautéing or grilling mushrooms at a high heat for the most intense flavor. Add small mushrooms to soups, salads, curries and casseroles. Large mushrooms, such as portobellos, provide fat-free vegetarian alternatives to hamburger patties.

Papaya - ya! About 80 precent of the papaya tested in the study done by EWG was pesticide-free. The fruits vibrant orange color is an indication of it's nutritional punch. One-half of a small papaya supplies 80 percent of your daily recommended intake of vitamin C, along with rich amounts of potassium, folic acid, beta-carotene and fiber. If you're concerned about genetically modified foods, you may want to go organic for this one -- a small portion of the papaya grown in the U.S. comes from GE seedstock.

10. Sweet Peas

Sweet peas have very little pesticide residue and are safe to buy as conventional (i.e. non-organic), according to the Environmental Working Group. One cup of sweet peas supplies a whopping 14 grams of fiber, making them one of the highest-fiber veggies. The Institute of Medicine recommends at least 25 grams of fiber per day per women and 38 grams for men under the age of 50 -- yet Americans consume an average of 15 daily grams. To add fiber, protein and a slew of other essential nutrients to your diet, incorporate frozen peas into chili, soups and casseroles.

Again, that thick skin comes in handy. Pesticide residue are unable to get past the cantaloupe's tough peel, protecting its juicy insides, making it one of Environmental Working Group’s “Clean 15.” “To ripen cantaloupe at home, leave at room temperature,” writes Heather Calcote, a registered dietitian in Washington D.C. Once ripe, Calcote suggests adding diced cantaloupe to brown rice and polenta for added color, flavor and nutrients.

Another reason to get sweet on sweet potatoes: They're less likely to contain high levels of pesticide residue compared to other produce. Loaded with betacarotene, potassium, vitamin C and fiber, they provide a source of satisfying, natural sweetness without excess calories and sugar.

13. Eggplant

An entire cup of cooked, cubed eggplant provides a mere 33 calories, along with valuable amounts of satiating fiber. Many of the pesticides used in producing eggplant do not remain on the skin of the plant, earning it a place on the Environmental Working Group’s “Clean 15” list and making eggplant a safer choice than high-pesticide vegetables. For a tasty dish, grill eggplant slices brushed with olive oil until the outsides are golden-brown. Then add desired seasoning, such as basil, oregano, garlic or a light dusting of sea salt.

14. Cabbage

Leafy vegetables need not be green to be nutritious. Whether white, red or purple, cabbage provides significant amounts of nutrients, including vitamin C and fiber, and markedly low calories, or about 13 per cup of cooked cabbage. Like kale, cabbage is a cruciferous vegetable that may guard against some types of cancer including colorectal cancers according to a recently published study. Unlike kale, which makes the Environmental Resource Group’s list of high-pesticide items, cabbage tends to contain little toxic residue.

The flavor isn’t the only sweet attribute of watermelon. The thick outer casing provides protection from pesticides in the soil. Watermelon may also help soothe those sore muscles and keep your ticker healthy. To keep your calorie intake and weight in-check, swap out high-calorie, low-nutrient sweets in your diet with sweet fruits, such as watermelon. Watermelon also makes a tasty addition to smoothies.
