EBN- A new study has found that your genetic makeup influences how starch shapes your oral microbiome—which in particular affects your risk of tooth decay and gum disease.
According to scientists from Cornell University, the gene AMY1 plays an important role in how bacteria in your mouth respond to starch. So, should you cut out starchy foods.
Most people are warned that if you eat a lot of sugar, make sure you brush your teeth ,” said Dr. Angela Paul, lead author and assistant professor of molecular nutrition at Cornell University, who conducted the research.
The takeaway here is that depending on your AMY1 copy number, you may want to be just as vigilant about brushing your teeth after eating those digestible starches,” she added.
What is AMY1 gene?
The AMY1 gene produces salivary amylase , an enzyme that helps digest starch in the mouth. It also affects the composition of oral bacteria, which may have implications for your dental health. Several previous studies have linked AMY1 to tooth decay and gum disease due to high levels of gut bacteria.
However, it has not been clear how salivary amylase interacts with its main substrate, starch, to alter the oral microbiome and increase disease risk.
How was the study conducted?
According to the researchers, they collected saliva samples from 31 adults, each with different AMY1 copy numbers, added starch to the cultured samples, or biofilms, and observed how the composition of the bacteria shifted.
Should you ditch the starch?
Experts believe the study results don’t mean you should cut starch out of your diet entirely. Starch is an important source of carbohydrates, which play a vital role in a balanced diet when eaten in moderation. They provide energy and fiber, along with essential vitamins and minerals.
Foods rich in starch include cereals, pasta, rice, bread, potatoes, beans, corn, and even bananas.
According to experts, you should reduce starchy foods from your diet, rather than eliminating them completely, and combine them with other nutrient-rich ingredients to improve oral health.
