Ascorbic Acid and the Corn Free Diet
Ascorbic acid is a water-soluble vitamin that acts as an antioxidant in the body, helping to protect cells from damage by free radicals. It is also essential for the synthesis of collagen, absorption of iron, and the maintenance of cartilage, bones, and teeth. In the food industry, ascorbic acid is used as a preservative and nutrient fortifier, helping to maintain the color and flavor of processed foods. It is usually synthesized through the fermentation of cornstarch, which may pose concerns for individuals with corn allergies or sensitivities.
