Choosing to adopt whole food nutrition may benefit one who is looking to adopt a healthier lifestyle, but although organic products generally only have water or salt added they can also be more expensive.

"The most important thing to consider is the health benefit of consuming five servings of fruits and vegetables every day," says dietitian Ashley Mullins at Baylor All Saints Medical Center, who adds "that’s the biggest payoff."

While more and more organic products are available at the neighborhood food shelves, they may cost somewhat more, and she says that to gain the most benefit, consumers who may have to choose should opt for products that would normally have the highest level of pesticides unless grown organically.

Fruits such as cherries, apples, imported grapes, peaches, strawberries, nectarines and pears topped the list for pesticide usage by the Environmental Working Group, along with vegetables like lettuce, sweet bell peppers and celery.

Another option may be to consider whole food supplements which offer the consumer the benefits of one healthy food or another, rather than a multivitamin that isolates specific components of several compounds.
