We should all be hygienic, right?
Wash our hands, brush our teeth, take a shower every day.
Not so fast, says a new study from Harvard University and published in the journal, Nitric Oxide. One daily hygienic habit, usually praised as very good, can increase your risk for diabetes by 30%.
Researchers analysed information on 1,206 overweight/obese adults collected by the San Juan Overweight Adults Longitudinal Study. The participants were between 40 and 65 years old and free of diabetes and heart problems.
– 43% used mouthwash at least once a day
– 22% used it at least twice a day
…and the rest didn’t use it at all.
Overall, 17% of the participants developed prediabetes or diabetes.
20% of those who used mouthwash at least once a day were struck by either of these two metabolic conditions. A 3% higher risk probably isn’t anything to worry about.
However, of those who gargled with mouthwash at least twice a day, a full 30% succumbed to prediabetes or diabetes, and that is certainly a huge increase in risk.
According to the study authors, over the counter mouthwash poorly discriminates between good and bad bacteria. It is strongly antibacterial and kills all bacteria, including the good ones.
This is problematic, as your body needs certain good bacteria to produce nitric oxide which is, in turn, responsible for regulating insulin levels.
Previous studies have shown that using dental floss and brushing your teeth is very beneficial for your health. But mouthwash seems to be overdoing it with hygiene.
