Sugar Is the Only Cause of Tooth Decay

Did You Know…that sugar is the ONLY cause of tooth decay, which negatively impacts virtually every aspect of your health?

On the heels of a UK study that declares sugar is the ONLY cause of tooth decay, we’re sounding the alarm on the deleterious effects of sugar once again.

Researchers from University College London and the London School of Hygiene & Tropical Medicine analyzed public health records from around the world, and what they found was unequivocal:  sugar, in any form, decays your teeth, which in turn erodes your health.

Tooth Decay Around the World 

The study, published in BMC Health, showed that during World War II, when sugar was rationed, tooth decay in Japan was “hugely reduced.”  However, once the war ended and sugar imports to Japan picked back up, tooth decay picked right back up, as well.

Also important were the findings on Nigeria, where sugar consumption is extremely minimal:

Only 2% of Nigerians have tooth decay
92% of American adults have tooth decay
60—90% of American children have tooth decay

America is the land of sugar, after all, with the majority of sugar coming from sodas and fruit juices. 

How Dental Decay Can Ruin Your Health 

Tooth decay ranks among the most common non-infectious diseases in the world.  It doesn’t just cause gum disease; it has a major impact on all aspects of health.

Eating a high sugar diet…

Leaves you susceptible to yeast infections
Exacerbates arthritis and asthma
Raises triglyceride levels
Increases your risk for obesity, hypertension, and type 2 diabetes


Scientists believe that oral bacteria in your mouth enter into your bloodstream and attack all your major organs.  Ultimately this can cause heart attack… dementia… rheumatoid arthritis… and, for pregnant women, premature birth.

For this reason, researchers are advocating for a disciplined cutback in sugar consumption.  They conclude:  “This means that it is now even more important to develop a radical prevention policy with a marked reduction in sugar intake since the use of fluoride on its own is insufficient to reduce substantially the burden of [cavities] over the lifetime of individual.”

They recommend limiting sugar consumption to 3% of total daily calories (which is just 60 calories out of 2000).  In comparison, the World Health Organization (WHO) suggests limiting sugar intake to 5% of total calories, with a 10% maximum.

You can measure your daily sugar intake using an online nutrient assessment tool, such as myfitnesspal.com, and then adjust your sugar consumption accordingly.
