Some fruits and vegetables are less likely to be contaminated with pesticide residues, so you can feel good about buying them conventional if you are trying to stick to a budget.

Eating more fruits and vegetables—organic or not—is better than eating none at all. Most of us would love to be able to buy organic produce all the time, but it can be expensive. You may wonder if the price is worth it for your health. Pesticides can be absorbed into fruits and vegetables, leaving trace residues. One way to limit your exposure is by choosing organic. But if that's not a financial reality for your family, you can also shop smarter: buy conventional produce that's the least likely to contain pesticide residues and save your organic dollars for produce that tends to have the highest amounts of pesticide residue (aka the Dirty Dozen).

Avocado Toast with Burrata

Every year, the Environmental Working Group (EWG), a nonprofit, nonpartisan organization, releases a Shopper's Guide to Pesticides that identifies fruits and vegetables with the highest and lowest pesticide residues. The Clean Fifteen is the list of foods that are least likely to be contaminated with pesticide residues, so if budget is a concern, you can feel good about buying these 15 fruits and vegetables conventional, starting with the least contaminated food.

1. Avocados

Good news, guacamole lovers! Avocados once again top the Clean 15 list. Of the conventional avocados tested, fewer than 1 percent contained pesticides (with only one pesticide found).

When it comes to pesticides, sweet corn is one of the cleanest conventional foods you can buy (less than 2 percent had any detected pesticide residues). A small amount of sweet corn is grown from genetically engineered seeds, so if you choose to avoid genetically engineered crops, opt for organic corn.

3. Pineapples
