Many people are confused about the differences among sucrose, fructose, and high fructose corn syrup. As Cathe Olson wrote in her article Sugar, High Fructose Corn Syrup, Agave Nectar: Which Should You Choose? excessive amounts of any of them can lead to a wide range of health problems. The USDA's Food Guide Pyramid recommends limiting added sugars to 12 teaspoons per day. Estimates are that Americans consume three times the recommended amount.The author reported (with a bibliography) that pesticides have been linked to many health problems including infertility, birth defects, and cancer. Therefore, she personally chooses to avoid sweeteners that may contain pesticides, herbicides, chemical bleaching agents, and genetic engineering; using instead organically-grown, unbleached cane sugar and organic raw agave nectar. Because high fructose corn syrup is unavailable in organic form, she does not use it. Each person will need to make a decision about sweeteners and Olson's article may help to shed light on the pros and cons. (Source)
