There seems to be a scientific basis for organic foods after all. Recent research found that:
Organic fruit and vegetables may be better for the heart and general health than eating conventionally grown crops, new research has found.
A ten-year study comparing organic tomatoes with standard produce found that they had almost double the quantity of antioxidants called flavonoids which help to prevent high blood pressure and thus reduce the likelihood of heart disease and strokes.
The article also discusses some of the mechanisms that lead to the organic veggies being healthier:
Plants produce flavonoids as a defence mechanism; they are triggered by nutrient deficiency. Feeding a plant with too many nutrients, such as inorganic nitrogen commonly found in conventional fertiliser, curbs the development of flavonoids. The lower levels of flavonoids in conventional tomatoes were caused by “over-fertilisation”, the research team concluded.
So eat your organic veggies before biting into that organic apple pie!
