Just before I started to type this post, I had a clémentine. Bought a bag of half filled clémentines that costs only £1 from Borough market. I like citrus fruits. However, one of my dentists once told me one time that citrus fruits cause erosion of enamel because of high acid concentration. Well, I guess to have citrus fruits moderately is acceptable in day-to-day life. Over consumption of anything in our diet might have more harm than benefit to our body.
