Learn about the role of E338 (phosphoric acid) in nutrition, its health effects, dietary sources, recommended intake, and alternatives.
E338, also known as phosphoric acid, plays a significant role in nutrition as both a food additive and a natural component of some foods. Phosphoric acid is commonly used in the food industry to add a tangy flavor to carbonated beverages, enhance the shelf life of processed foods, and adjust the acidity of various products.
While phosphoric acid is generally recognized as safe by the FDA, excessive consumption of foods and drinks containing E338 may have negative health effects. Some studies suggest that high intake of phosphoric acid may contribute to bone mineral density loss and dental erosion.
Phosphoric acid can be found in a variety of processed foods and beverages, including soda, processed meats, and some dairy products. It is also naturally present in some fruits and vegetables, albeit in smaller amounts.
As with any food additive, moderation is key when it comes to consuming E338. It is important to read food labels and be mindful of your overall intake of processed foods that may contain phosphoric acid.
If you are looking to reduce your consumption of phosphoric acid, consider opting for natural beverages like water, herbal teas, or freshly squeezed juices. Choosing whole foods over processed options can also help minimize your intake of E338.
