I was reading my Sunday paper a few weeks ago and saw an interesting article from Parade Magazine that talks about secrets to a bright smile. At the dentist’s office, you often hear about brushing and flossing as a way to keeping your gums healthy; however, the Parade Magazine article passes on findings from a new research. This new research shows ways to help keep gums “in the pink” through eating these five foods.

Here’s what Parade Magazine says about the “5 surprising secrets to a great smile”:

1. Salmon
This fish is rich in omega-3 fatty acids, which reduce inflammation all over the body, including the gums. A study found that people who ate the most omega-3’s slashed their risk of gingivitis by up to 20 percent.

2. Strawberries
They’re bursting with vitamin C, which builds collagen, an important component of healthy gum tissue. In fact, people who consume less than 60 milligrams of C each day (the amount in six large strawberries) are 150 percent more likely to develop gingivitis. But stay away from fizzy vitamin supplement drinks; they have been shown to erode tooth enamel.

3. Whole-Grain Bread
Whole grains contain iron and B vitamins—nutrients essential to gum health. One large study found that eating three servings daily reduced the risk of gum disease by 23 percent. Barley, oatmeal, and brown rice count, too.

4. Green Tea
Hot or iced, this brew is brimming with antioxidants that kill the bacteria that lead to gingivitis. Bonus: The beverage also wipes out the germs that cause bad breath.

5. Pistachios
These nuts are rich in the antioxidant CoQ10, shown to fight gum inflammation. If you already have gingivitis, ask your dentist or doctor whether you could benefit from a CoQ10 supplement.

Surprised? Many are also surprised at the fact that 75% of Americans are affected by some form of periodontal disease (according to the American Academy of Periodontology). Diet plays an important part of overall oral health, and maintaining a healthy diet is a simple way to help keep your gums healthy. As a precaution, check-in with your dentist regularly in order to catch warning signs for gum diseases to maintain your best smile.
