RefinedSugarCouldBeHarmingMoreThanYourTeeth

You've probably heard your dentist say more than once to cut back on sweets. That's good advice not only for keeping your teeth healthy, but your whole body as well.

As a carbohydrate, a macronutrient that helps supply energy to the body's cells, sugar is prevalent naturally in many foods, particularly fruits and dairy. The form of which we're most concerned, though, is refined sugar added to candy, pastries and other processed foods.

Believe it or not, three out of four of the 600,000 food items on supermarket shelves contain refined sugar, often hiding under names like "high fructose corn syrup" or "evaporated cane syrup." So-called healthy foods with labels like "low fat" or "diet" have added sugar and chemicals to replace the taste of fat they've removed.

But perhaps the biggest sugar sources in the average U.S. diet are sodas, energy drinks, and sports drinks. With the added volume of sugar in processed foods, the growing consumption of sweetened beverages has pushed the average American's sugar intake to nearly 20 teaspoons a day—more than three times the recommended daily allowance.

And right along with the increased consumption of sugar, cases of Type 2 diabetes, heart disease and other systemic diseases have likewise risen. And, yes, preventable tooth decay continues to be a problem, especially in children, with sugar a major contributing factor in the prevalence of cavities.

So, what can you do to keep your daily sugar intake within healthy bounds?

  • Check ingredient labels on packaged food for added sugar, chemicals or preservatives. If it contains sugar or "scientific"-sounding ingredients, leave it on the shelf.
  • Be wary of health claims on food packaging. "Low fat," for example, is usually an indicator of added sugar.
  • Drink water or unsweetened beverages instead of sodas, sports drinks or even juices. Doing so will vastly lower your daily intake of sugar.

A healthy diet with much less sugar and regular exercise will help you stay healthy. And with a lower risk for tooth decay, your teeth will also reap the benefits.

3SurprisingFoodsThatCouldHelpYouFightToothDecay

You've no doubt heard about certain foods and beverages that increase your risk for dental disease. These foods, often high in added sugar or acid, can lead to tooth decay or periodontal (gum) disease.

But have you heard about foods with the opposite effect — actually protecting your teeth against disease? Many of these dental-friendly foods are plant-based and fibrous: they stimulate saliva production, one of the mouth's best disease-fighting weapons.

But there are also some foods you might not expect to make the good list for dental health. Here are 3 surprising foods that could help you fight dental disease.

Cheese. We've long recognized milk as important to dental health — but cultured dairy products like cheese are also good for teeth. Cheese stimulates saliva, which neutralizes acid and replenishes the enamel's mineral content. Cheese also contains decay-stopping minerals like calcium, phosphorous and casein. And although milk cheese contains the sugar lactose, this particular type triggers less acid production than other sugars.

Black & green teas. You may have heard about the staining effect of tea, and avoided it as a result. But both forms of tea are also rich in antioxidants, substances that protect us against disease, including in the mouth. Black tea also contains fluoride, which strengthens enamel against cavities. If you drink tea, of course, you should exercise diligent hygiene to reduce any staining effect.

Chocolate. Yes, you read that right, chocolate: unrefined cocoa to be exact, which contains a number of compounds that resist decay. Ah, but there's a catch — chocolate in the form of your favorite candy bar usually contains high amounts of sugar. Sweetened chocolate, then, is a mixed bag of decay-resistive compounds and decay-promoting sugar. To get the benefit you'll have to partake of this favorite food of the Aztecs in a more raw, less sweetened form.

Of course, there's no single wonder food that prevents tooth decay. Your best approach is a diet rich in fresh fruits and vegetables, dairy and quality protein while limiting sugar-added and acidic foods. And don't forget daily brushing and flossing, coupled with regular dental visits for cleanings and checkups. Having a comprehensive dental care plan will help ensure your teeth remain healthy and disease-free.

ReduceSugarConsumption-foraHealthierMouthandBody

Tooth decay doesn't appear out of nowhere. It begins with bacteria, which produce acid that softens and erodes tooth enamel. Without adequate enamel protection, cavities can develop.

So, one of our prevention goals is to decrease populations of disease-causing bacteria. One way is to deprive them of carbohydrates, a prime food source, most notably refined sugar. That's why for decades dentists have instructed patients to limit their intake of sugar, especially between meal snacks.

Ironically, we're now consuming more rather than less sugar from a generation ago. The higher consumption impacts more than dental health — it's believed to be a contributing factor in many health problems, especially in children. Thirty years ago it was nearly impossible to find a child in the U.S. with type 2 diabetes: today, there are over 50,000 documented juvenile cases.

Cutting back isn't easy. For one thing, we're hard-wired for sweet-tasting foods. Our ancestors trusted such foods when there was limited food safety knowledge. Most of us today still have our "sweet tooth."

There's also another factor: the processed food industry. When food researchers concluded fats were a health hazard the government changed dietary guidelines. Food processors faced a problem because they used fats as a flavor enhancer. To restore flavor they began adding small amounts of sugar to foods like lunch meat, bread, tomato sauce and peanut butter. Today, three-quarters of the 600,000 available processed food items contain some form of added sugar.

Although difficult given your available supermarket choices, limiting your sugar intake to the recommended 6 teaspoons a day will reduce your risk for dental and some general diseases. There are things you can do: replace processed foods with more fresh fruits and vegetables; read food labels for sugar content to make better purchasing decisions; drink water for hydration rather than soda (which can contain two-thirds of your daily recommended sugar allowance), sports drinks or juices; and exercise regularly.

Keeping your sugar consumption under control will help you reduce the risk of tooth decay. You'll be helping your overall health too.

ArtificialSweetenersareByandLargeaSafeAlternativetoSugar

Refined sugar is a prime food source for disease-causing oral bacteria. As bacteria consume sugar they produce high levels of acid that over time can erode enamel and leave a tooth vulnerable for decay.

The solution to stopping this vicious process is simple: cut back on eating refined sugar. The reality, though, is a bit more complicated. Many of us seem genetically hard-wired with a “sweet tooth,” perhaps a remnant of our early ancestors' sense that sweet foods were a safe means to obtain energy.

Food manufacturers likewise don't help with making this dietary change — the number of items with added sugar has ballooned over the last several decades. We can trace a lot of this back to the unintended consequences of past government guidelines that called for removing fat from processed foods. But this also removed flavor, so manufacturers began adding sugar (under a myriad of names) to compensate.

Sugar consumption is now a hot health topic for its suspected connection with inflammatory diseases like diabetes and cardiovascular disease, as well as dental health. We now have a love-hate relationship with sugar — we want to show it the door but we can't quite bring ourselves to let it go.

The situation has created a market for artificial sweeteners. The amount and types of sugar alternatives has exploded since saccharine first emerged in the early 1960s. With these increased choices, though, there have also been increased concerns over their health impact, including in the mouth.

This concern has prompted numerous research studies. The conclusion: artificial sweeteners don't adversely affect the health of most people. And, from a dental perspective, artificial sweeteners can have a positive impact on teeth and gum health because unlike refined sugar they don't promote oral bacterial growth.

In fact, one particular sweetener may be even more beneficial to your teeth: xylitol. This sweetener, which comes from a sugar alcohol that oral bacteria can't digest, is often found in chewing gums, hard candies or mints.  In effect, xylitol “starves out” bacteria to help prevent tooth decay.

From a dental perspective, replacing sugar with an artificial sweetener (especially xylitol) can be advantageous. And less sugar could mean more good news after your next dental checkup.

WhytheBottledVarietyMightnotbeYourBestChoiceforCleanDrinkingWater

In recent decades civilization's millennia-long search for clean, safe drinking water has become much easier with modern purification methods. Today, there are few places in the United States without adequate access to potable water. And about three-fourths of the nation's tap water systems add fluoride, credited with helping to reduce tooth decay over the past half century.

But in recent years some have voiced concerns about the safety of tap water and popularizing an alternative: bottled water. Manufacturers of bottled water routinely market their products as safer and healthier than what comes out of your faucet.

But is that true? A few years ago a non-profit consumer organization called the Environmental Working Group (EWG) performed a detailed, comprehensive study of bottled water. Here's some of what they found.

Lack of transparency. It's not always easy to uncover bottled water sources (in some cases, it might actually begin as tap water), how it's processed, or what's in it. That's because unlike water utilities, which are rigorously monitored by the Environmental Protection Agency (EPA), the Food and Drug Administration (FDA) oversees bottled water production with less strenuous guidelines on labeling. Eight out of the top 10 selling brands were less than forthcoming about their water's contents in EWG's investigation.

Higher cost. According to the EPA, the average consumer cost in the last decade for tap water was $2.00 per 1,000 gallons (0.2 cents per gallon). The retail cost for even bulk bottled water is exponentially higher. It can be a costly expenditure for a family to obtain most of their potable water by way of bottled—while still paying for tap water for bathing and other necessities.

Environmental impact. Bottled water is often marketed as the better environmental choice. But bottled water production, packaging and distribution can pose a significant environmental impact. EWG estimated the total production and distribution of bottled water consumes more than 30 million barrels of oil each year. And disposable plastic water bottles have become one of the fastest growing solid waste items at about 4 billion pounds annually.

While there are credible concerns about tap water contaminants, consumers can usually take matters into their own hands with an affordable and effective household filtering system.  EWG therefore recommends filtered tap water instead of bottled water for household use.
