Eating a diet of whole foods is good for you, no doubt. And, it seems that our early ancestors understood that plants were healthy nourishment, long before the developement of agriculture.
Last summer, an international team of researchers excavated 9,000 year old skeletons in South Sudan. The researchers found that plants played a significant role in their diets.
According to research from the University of York, in England, by extracting chemical compounds and micro-fossils from dental calculus (calcified dental plaque) from ancient teeth, the researchers were able to provide an entirely new perspective on our ancestor’s diets. The researchers found that our ancestors’ ingested the purple nut sedge plant in both pre-agricultural and agricultural periods.
Their research suggests that the plant has the ability to inhibit Streptococcus mutans, a bacterium which contributes to tooth decay. Thus, this may have contributed to the unexpectedly low-level of cavities found in the agricultural population. Additionally, the plant is chock full of carbohydrates, is medicinally useful, is aromatic, and even contains lysine, an essential amino acid.
We’ve all heard this adage before: “A diet rich in nutrients and vitamins is good for you!” or “Eat your leafy greens!” Healthy foods contribute to overall health, which contributes to good oral health. And, that’s something we can all chew on.
