3. Garlic and Onions
Who cares if they give you bad breath? Garlic and onions can whiten teeth, you know. Joan Salge Blake, a registered dietitian, says it’s because onions contain sulfur. Blake is a spokesperson for the Academy of Nutrition and Diatetics.
Bacteria causes dental carries and tooth decay, but they also prevent you from getting the pearly whites you desire. They create an acidic environment that erodes tooth enamel and makes them susceptible to staining. Bacteria also form plaques which lead to obvious discoloration and yellowing of the teeth. Lucky for you, garlic and onions are rich in thiosulfinates and thiosulfonates, two sulfuric compounds with antibacterial properties. They too are rich in allicin, another compound that stops bacteria from proliferating in the mouth. Altogether, these natural components whiten teeth by preventing the formation of plaque and reducing risks for staining.
Experts say you shouldn’t cook garlic and onions – they should be eaten raw. Cooking breaks down allicin and sulfurs, stripping them of any teeth whitening benefits.
How to whiten your teeth: Add sliced raw onions into sandwiches and salads. You can also use garlic-infused olive oil with foods. If you’re worried about bad breath, just brush your teeth afterwards.
