Answer
Yes, acetic acid is safe to eat in food when used in appropriate concentrations. It's recognized as Generally Recognized As Safe (GRAS) by food safety authorities worldwide when consumed in typical amounts found in foods and vinegar. The diluted form in vinegar (4-7% acetic acid) has been consumed safely for thousands of years. However, concentrated acetic acid (above 10%) can cause burns and should never be consumed directly. In normal dietary amounts, acetic acid poses no health risks and may even offer benefits like improved digestion and blood sugar regulation.
