A Quick Tip by Raederle

Orange juice is a popular beverage. It is a source of vitamin C (ascorbic acid), potassium, folic acid (Vitamin B9). Citrus juices also contain flavonoids that are believed to have beneficial health effects. However, if drunk on an empty stomach, orange juice can exacerbate present gastro-intestinal conditions and/or cause mild and temporary stomach upset. Due to the citric acid, orange juice typically has a pH of 3.5. Drinking or sipping orange juice can therefore cause erosion of the tooth enamel, otherwise known as 'acid erosion'. It is recommended to use a straw so that the juice does not come into contact with the teeth. 200 ml (about 7 ounces) of orange juice accounts for 1 of the recommended 5 pieces of fruit a day.
