Medical Miracle in the Quran?

This sort of proof is often offered as evidence of the miraculous and divine nature of the Quran:

IT is a long-established custom among Muslim parents to put a piece of well-chewed date (or other available sweet fruit) in the mouth of a newborn baby. Muslims do this following the practice of the Prophet Muhammad (Pbuh), believing him to be, as the Qur’an says, sent as a healing and a mercy to mankind. We may infer from the way this custom originated that there is a virtue in it. There is - complimentary to the virtue and pleasure of following the Sunnah (the practice of the Prophet) - placing a ‘sugary substance’ inside the mouth of a new-born baby dramatically reduces pain sensation and heart rate. An interesting scientific medical study, published in the British Medical Journal (No 6993, 10 June 1995), proved beyond any doubt the benefit of giving a new-born child sugar, in order to reduce the feeling of any painful procedure like heel pricking for a blood sample or before circumcision.

The study, entitled ‘The analgesic (pain killing) effect of sucrose in full term infants: a randomised controlled trial’, was done by Nora Haouari, Christopher Wood, Gillian Griffiths and Malcolm Levene in the post-natal ward in the Leeds General Infirmary in England. 60 healthy infants of gestational age 37-42 weeks and postnatal age of 1-6 days, were randomized to receive 2ml of one of the four solutions: 12.5% sucrose, 25% sucrose, 50% sucrose, and sterile water (control).

The first group of 30 babies received sugar syrup before a routine blood test (heel pricking, which is usually painful) done to detect jaundice. The other 30 babies were given only sterile water as a control group. Placing 2ml of a 25% or 50% sucrose solution on the tongue before pricking the heel significantly reduced the crying time, compared to babies who got water. Also, their heart rate returned to normal more quickly. The stronger sugar solution had the greater effect, crying being reduced further with increasing concentration of sucrose. From which we may conclude that sucrose (sugar) placed on the tongue may be a useful and safe form of analgesia for use with newborn infants. [...]

Ergo: the custom of placing a date (high in sugar) on the child's tongue shows that Islam miraculously foretold this later scientific development.
