Three new European studies have revealed that organic tomatoes, peaches and processed apples all have higher nutritional quality than non-organic.

Researchers found that organic tomatoes "contained more dry matter, total and reducing sugars, vitamin C, B-carotene and flavonoids in comparison to the conventional ones", while conventional tomatoes in this study were richer in lycopene and organic acids.

Previous research has found organic tomatoes have higher levels of vitamin C, vitamin A and lycopene.

In the latest study, the scientists conclude "organic cherry and standard tomatoes can be recommended as part of a healthy diet including plant products which have shown to be of value in cancer prevention."

A French study has found that organic peaches "have a higher polyphenol content at harvest" and concludes that organic production has "positive effects on nutritional quality and taste".

In a further study just published, organic apple puree was found to contain "more bio-active substances - total phenols, flavonoids and vitamin C - in comparison to conventional apple preserves" and the researchers conclude "organic apple preserves can be recommended as valuable fruit products, which can contribute to a healthy diet".
