　　素材段落

　　Organic food is much healthier than conventional food due to its higher levels of antioxidants and lower levels of pesticides. Antioxidants have been linked to a lower risk of cancer and other diseases in humans. Scientists have discovered that organic food contains an average of 17% more antioxidants than conventional food. The reason for this is because plants naturally produce antioxidants to defend themselves against pests and diseases. When pesticides are applied to plants, they lose their need to generateantioxidants for their own defenses. It is also important to note that pesticide residues are found to be three to four times more likely on conventional food as compared to organic food. This data is based on a recent study conducted by Dr. Benbrook from the Center for Sustaining Agriculture and Natural Resources at Washington State University. Pesticide residues can cause dizziness and headaches (as their acute effects) and neurological problems and birth defects (as their long-term effects).
