Tea would be great natural whitener: The latest news from the dental industry says that tea, according to the latest research, also helps strengthen tooth enamel and prevent tooth decay.
The most consumed drink in the world, especially in Eastern countries, contains large quantities of fluorine, thus revealing itself as a precious food able to defend our teeth from the attacks of food acids.
In fact, the tea plant absorbs fluoride from the soil, enriching itself with this precious mineral, very useful for dental health.
The study comes this time fromEngland, and precisely by the dietician TJ Bond who, together with the nutritionist Carrie HS Ruxton, has published the results of his studies in the well-known journal Nutrition Bulletin.
The ideal dose to take per day to have a good daily defense of fluoride that guarantees the health of the teeth would be 4 cups of black tea. To declare it is the doctor Carrie, who is also a member of the Tea Advisory Panel Freelance Dietitian of London, who also explained that the longer the tea is left to infuse, the greater the benefits it will bring to the teeth.
The two researchers' study focused on 49 types of tea bags. preparing three infusions from each sachet and mixing the cups. With this method, it was possible to calculate the average amount of fluoride present in each cup.
After the experiment and identified amounts of fluoride from 0.72 to 1.68 mg per cup, they were also able to discover that the greatest quantities of fluoride were found in the cheapest tea bags and in the decaffeinated ones.
The discovery of the two researchers is opening up new possibilities for intervention in the food and pharmaceutical industries, which will focus on products based on black tea.
To enrich this discovery is also another surprising news: milk tea would be an excellent natural whitener for the teeth.
All thanks to casein, the most important protein in milk, which is able to capture tannins, keeping teeth whiter.
This other discovery comes fromUniversity of Alberta and precisely from Ava Chow.
Born from a simple didactic experiment, it then brought to light interesting results, also published
onInternational Journal of Dental Hygiene.
The researcher's study was able to highlight the change in color of the extracted teeth, after they had been kept for a day immersed in pure tea and in latte macchiato tea.
Milk, or rather the casein of milk, has reduced color, with an efficacy index equal to that of many other whitening products on the market and with higher coefficients than even many specific toothpastes.
