Orange juice, a popular morning beverage, can be challenging for some people to digest and may lead to discomfort, though it does not directly cause gastroenteritis, an inflammation of the stomach and intestines. According to dietitian and nutritionist Nathalie Negro, orange juice contains high levels of organic acids, particularly citric acid, which can irritate the esophagus and contribute to conditions such as gastroesophageal reflux, inflammation, and a burning sensation in the chest. Additionally, its high sugar content, when consumed in large amounts, may cause irritation in the stomach and lead to symptoms such as bloating, discomfort, or even diarrhea. Nathalie Negro suggests that limiting the intake of orange juice is the best approach for minimizing digestive issues. She also emphasizes the importance of proper storage to prevent fermentation, which could lead to harmful bacteria growth and, in extreme cases, food poisoning or gastroenteritis. She recommends that orange juice be consumed at room temperature rather than directly from the refrigerator, as cold temperatures can further irritate the digestive system. Individuals with specific health conditions, such as esophagitis, which is inflammation of the esophagus, or irritable bowel syndrome (IBS), particularly those who experience frequent diarrhea, should be especially cautious when consuming orange juice. For these individuals, the acidity and sugar content of orange juice can worsen their symptoms and lead to increased discomfort. When choosing between homemade and commercially produced orange juice, Negro generally favors the latter. This is because homemade orange juice is more prone to spoilage due to the lack of industrial sterilization processes. Industrial orange juices, on the other hand, are subject to stricter quality control and processing standards. In France, since 2012, it has been illegal to add extra sugar to fruit juices, which may result in commercially available orange juices containing less sugar than homemade versions.
