Science is showing that organic fruits and vegetables not only taste better, but they are better for you. Nutrient content in organic fruits and vegetables is, on average, higher than in conventionally grown fruits and vegetables. In many cases, the amount of antioxidants found in organic fruits and vegetables is 30-percent higher compared to conventionally grown produce.
Taste plays a huge factor in converting consumers to try new foods and according to a Minnesota Opinion Research Inc. poll, 43 percent of consumers say taste is a major reason why they purchase organic fruits and vegetables. So what are the other 57 percent waiting for?
"People have a lot of misconceptions about what an organic meal tastes like," says celebrity chef Akasha Richmond. Eighty-five to 90 percent of the ingredients she uses in her A-list recipes are organic. "Because organic is associated with something that is good for you, people think it will be too healthy and have no taste. But after they try it, most people are shocked at how much more flavor some of their favorite foods have."
And while chefs like Richmond have known instinctively for years that organic produce can add flavor to their menus, a new state of science review, published by The Organic Center, shows why organic fruits and vegetables often taste better.
Published studies have analyzed the sensory appeal of organic fruits and vegetables compared to their conventional counterparts.
Organic fruits and vegetables tend to score higher in taste because they are sweeter than conventionally grown foods. Scientists say this is because of the nutrient density of organic produce and their smaller size. Conventional farming methods are designed to produce bigger fruits and vegetables, but increasing cells size adds more water, diluting the concentrations of both vitamins and natural flavors.
Organic apples, strawberries and tomatoes showed some of the most significant differences in taste, according to the report.
The report also dispels another misconception about freshness. Contrary to what most people believe, organic fruits and vegetables often have a longer shelf life than conventionally grown foods. The higher levels of antioxidants, considered a natural preservative, are actually part of what enables some organic fruits and vegetables to store longer. The other contributing factor is the lower levels of nitrates that come from synthetic fertilizers, which aren't used in organic farming.

Organic Plant-Based Foods ARE More Nutritious, and Provide on Average a 25% Nutrition Premium
BOULDER, Colo. - March 18, 2008 - A comprehensive review of 97 published studies comparing the nutritional quality of organic and conventional foods shows that organic plant-based foods (fruits, vegetables, grains) contain higher levels of eight of 11 nutrients studied, including significantly greater concentrations of the health-promoting polyphenols and antioxidants.
In this first comprehensive review of the scientific literature comparing nutrient levels in organic and conventional food completed since 2003, a team of scientists conclude that organically grown plant-based foods are 25% more nutrient dense, on average, and hence deliver more essential nutrients per serving or calorie consumed.
Magnitude of Differences Heavily Favors Organic Foods
Several methods were used to place the magnitude of the differences in nutrient levels between organic and conventional foods into perspective. In two-thirds of the matched pairs favoring the conventional food, the differences in favor of conventional were under 10%, compared to 26% of the matched pairs in which the organic food was more nutrient dense by a margin under 10%.
The premium in favor of the conventional food was 21% or greater in just 15% of the matched pairs in which the conventional food was more nutrient dense, whereas in the more nutrient dense organic food matched pairs, 41% favored organic by 21% or more, and 24% of the pairs were 31% or more nutrient dense.
The largest differences were in the case of the flavonoid quercetin, where the organic foods were 2.4-times more nutrient dense on average, and nitrates, where levels were 1.8-fold lower in organic foods (a desirable nutritional feature).
The consistency of the differences observed, the relative importance of the nutrients for which the organic samples tended to be markedly higher, and the sizable advantage in many of the organic foods within matched pairs lead the team to conclude -
"Yes, organic plant-based foods are, on average, more nutritious in terms of their nutrient density for compounds validated by this study's rigorous methodology."
Commenting on the results, Dr. Neal Davies, a professor in the School of Pharmacology at Washington State University, and a study co-author, said "We have carried out many careful comparisons of both nutrient levels and biological activity of antioxidant polyphenols in organic and conventional foods over the last five years. Not only are we seeing a general trend in favor of the nutrient density of organic food, but also evidence that nutrients are often present in organic foods in a more biologically active form."

ARE More Nutritious, and Provide on Average a 25% Nutrition Premium

Nutrient levels were studied in 236 matched pairs of foods with scientifically valid results on the levels of 10 nutrients, plus nitrates (high levels are undesirable because of food safety risks). Each matched pair contains, for example, an apple crop grown organically and another apple crop from a nearby conventional farm with similar soils, climate, plant genetics, irrigation systems, nitrogen levels, and harvest practices.
The new report is published as a "State of Science Review" by The Organic Center and is entitled "New Evidence Confirms the Nutritional Superiority of Plant-based Organic Foods." The co-authors are Charles Benbrook, the Center's Chief Scientist, Xin Zhao of the University of Florida, and three Washington State University (WSU) scientists Jaime Yanez, Neal Davies, and Preston Andrews. Dr. Andrew Weil, a Center board member, wrote the "Foreword."
