The graph shows information about the consumption of sugar and honey and the possibility of tooth decay.
The PH level at which tooth decay is unlikely is 5.5. Below that it's quite possible to happen. The safest of three of them(fruit sugar, cane sugar and honey) is honey. That's because the PH level is falling only for 5 minutes to 4.7, when it stabilises for another 5, and it goes up to safety after 13 minutes in. While fruit sugar makes your PH levels decrease for only five minutes, too, its rise is slower than the one done by honey.
The most dangerous is cane sugar. It makes your PH level go down to 2.5, and it's crawling up very leisurely . Tooth decay is unlikely to occur only after 30 minutes! That's very slow compared to the others.
In conclusion, honey is the least likely to cause tooth decay, while the other two are more alarming.
