Excess of this food can cause tooth decay and impact dental health and no, it is not sugar

Whenever dental health is talked about, we often think staying away from sugar would solve all the problems. However, a recent study reveals an unexpected food item can lead to tooth decay if consumed in excess amounts. Unlike sugar, which feeds cavity-causing bacteria, this food item is linked to inflammation and oral bacteria changes, and thus impacts overall dental health.


A study conducted by researchers at King’s college London found individuals who consumed higher amounts of Red Meat experienced higher levels of periodontal inflammation. Another study found that higher meat consumption was associated with increased risk for periodontal disease.


How does red meat impact dental health?Red meat affects gums and bone health by causing inflammation, oral microbiome changes and cooking byproducts that promote oxidative stress and tissue damage.

• Inflammation: Red meat is high in saturated fat and can promote the production of pro-inflammatory molecules in the body. Over time, inflammation can break down the bone and ligaments that support teeth which can even lead to tooth loss. Chronic inflammation or swollen gums can lead to periodontitis, which is a condition where gums pull away from teeth.

• Oral microbiome changes: Humans host a complex community of bacteria, and a microbiome resides in the mouth too. Some of these bacteria are good, while some others can be harmful. Diets high in animal protein can increase a bunch of harmful bacteria that are linked to gum disease. Bacteria such as Porphyromonas gingivalis and Treponema denticola, produce enzymes that destroy gum tissue and trigger the immune system, which causes even more inflammation. A plant rich diet on the other hand keeps the harmful bacteria under control.

• Oxidative stress from cooking byproducts: The method of cooking also plays a role in affecting dental health. High-heat methods like grilling, frying or barbecuing can lead to oxidative stress. Compounds released in the process such as advanced glycation end products (AGEs), which can speed up aging of tissues, including gum tissue. Similarly heterocyclic amines (HCAs) trigger oxidative stress and have been linked to DNA damage and inflammation.

It is clear that excess consumption of red meat can quietly damage oral health. But here’s the key, red meat isn’t the enemy. Red meat is an excellent source of high-quality protein, iron, zinc and vitamin B12. All these elements are crucial for healthy gums, teeth and bone. Since the excess of anything can be harmful, red meat too falls in this category. If consumed in moderate amounts, with mindful cooking, red meat can be an excellent nutrient source for the body.
