MAX FACTS hydroponic news, tips and trivia Study Reveals Organic Tomato Juice Better for You A Spanish study has revealed that organic tomato juice contains more phenolic components than juice from conventionally grown crops. Polyphenols are a family of natural compounds with important nutritional properties that can protect the body against cardiovascular and degenerative diseases and some forms of cancer. Spanish researchers found significant differences between the levels of bioactive components in organic tomatoes and the levels found in those grown conventionally.

The report cited an experiment showing how shoots and fruit have been shown to be three to 17 per cent smaller for every degree Celsius of warming in a variety of plants. “Impacts could range from food resources becoming more limited (less food produced on the same amount of land) to wholesale biodiversity loss and eventual catastrophic cascades of ecosystem services,” warned co-author David Bickford.
