Tooth decay bacteria evolved as diet changed

Tooth decay bacteria evolved as diet changed | Nutrition | Scoop.it
Mesolithic hunter-gatherers living on a meat-dominated, grain-free diet had much healthier mouths that we have today, with almost no cavities and gum disease-associated bacteria, a genetic study of ancient dental plaque has revealed.

 

An international team of researchers, led by a group at the Australian Centre for Ancient DNA, University of Adelaide, extracted DNA from dental plaque from 34 prehistoric northern European human skeletons, and traced the changes in the nature of oral bacteria from the last hunter-gatherers to Neolithic and medieval farmers and modern individuals.

 

"Dental plaque represents the only easily accessible source of preserved human bacteria," says lead author Dr Christina Adler, now associate lecturer in dentistry at the University of Sydney.

 

The researchers found the composition of bacteria changed with the introduction of farming and again 150 years ago during the Industrial Revolution.

 

In contrast to the hunter-gatherer and early agriculturist diet, a modern diet full of refined carbohydrates and sugars has given us mouths dominated by cavity-causing bacteria.

 

"What we found was that the early [hunter-gatherer] groups really had a lot lower frequencies of any of the disease-associated bacteria compared to what you see today [and] that the number of species per person's mouth, or the diversity, was much higher in the past," says Adler.

 

However, while the researchers noted that bacteria associated with dental cavities such as S. mutans became dominant around the time of the Industrial Revolution, the frequency of bacteria associated with periodontal diseases such as gingivitis has not changed much since farming began.

 

This may have implications for the notion that gum disease and associated bacteria are a significant contributor to the recent increase in conditions such as cardiovascular disease and atherosclerotic plaques, says co-author Professor Alan Cooper, director of the Australian Centre for Ancient DNA.

 

"It has been suggested that the presence of this permanent inflammation state along the gums was promoting an immune inflammatory response, which in turn leads to cardiovascular disease," says Cooper.

 

"The idea was that a recent increase in the bacteria P. gingivalis [which causes gingivitis], was associated with the recent increases in cardiovascular disease, however we could show that this particular species has been fairly stable throughout the farming period."

 

The results will no doubt be good news for advocates of the so-called 'paleolithic diet' - high in meat, low in grains. Cooper says it would be interesting to study the effects of the diet on the bacterial population of the mouths, particularly after reseeding with healthy bacteria.

All the way up until the invention of margarine, saturated fats were a staple of our diet. That changed, when a propaganda campaign told us to lay off butter and lard and change over to "healthy" margarine. 

The campaign was so successful, it changed medicine and dietary recommendations. The result: Heart disease has become prevalent in the developed countries, and pharmaceutical corporations made a killing (in more ways than one) with the sale of proprietary "cholesterol lowering" drugs.

FIve diets that have no research support and make little common sense but have had significant popularity.  Eat what you enjoy, but stay lean: avoid what you don't love and continually reasses what you can do without.

Daddyjo's curator insight, July 21, 2014 11:18 AM

Fad diets are just a bunch of bogus nonsense. They make you feel lethargic, tired and weak. At the end of the diet, you may have lost weight, but it is mostly water weight and the minute you go back to your old diet, you gain back everything you have 'lost' and are back to square one. I've done fad diets alot in my past and trust me, it doesn't work! #eatclean

Will Humanity Face a Carbohydrate Shortage? Currently humanity uses around 40% of Earth's photosynthesis

Will Humanity Face a Carbohydrate Shortage? Currently humanity uses around 40% of Earth's photosynthesis | Nutrition | Scoop.it

Photosynthesis is the single most important transformation on Earth. Using the energy in sunlight, all plants—from single-celled algae to towering redwoods—knit carbon dioxide and water into food and release oxygen as a byproduct. Every year, humanity uses up roughly 40 percent of the planet’s photosynthesis for our own purposes—from feeding a growing population to biofuels. Given that growing human population, is there a limit to how much of the world’s photosynthesis we can appropriate?

 

Satellite measurements now allow precise measurements of the amount of photosynthesis taking place on the planet’s seven continents and assorted islands—or what scientists call “net primary productivity.” Such measurements are based on the amount of ground covered by plants, the density of that growth, and observations of temperature, sunlight and available water. Using these measurements, ecological modeler Steven Running of the University of Montana concludes that plants produce nearly 54 billion metric tons of carbohydrates a year—the bulk of it the complex organic chains of cellulose and lignin.

 

Running has also looked back over the past 30 years and discovered that the total amount of photosynthesis is surprisingly stable. Despite local weather that ranged from droughts to floods, plants soldier on producing roughly the same amount of food year in and year out, varying by less than 2 percent annually. This may be because the inputs of photosynthesis also vary so little—sunlight strength fluctuates only mildly, as does precipitation on a global basis. This finding suggests to Running that the plants’ “net primary productivity” might be usefully thought of as a planetary boundary, a threshold or safe limit for human impacts on natural systems.

 

Uur population is estimated to swell to 9 billion by 2050. Will the photosynthesis on this planet be able to keep up?

*Lipid Nanotechnology*

by
Mashaghi S, Jadidi T, Koenderink G, Mashaghi A.

"Nanotechnology is a multidisciplinary field that covers a vast and diverse array of devices and machines derived from engineering, physics, materials science, chemistry and biology. These devices have found applications in biomedical sciences, such as targeted drug delivery, bio-imaging, sensing and diagnosis of pathologies at early stages. In these applications, nano-devices typically interface with the plasma membrane of cells. On the other hand, naturally occurring nanostructures in biology have been a source of inspiration for new nanotechnological designs and hybrid nanostructures made of biological and non-biological, organic and inorganic building blocks. Lipids, with their amphiphilicity, diversity of head and tail chemistry, and antifouling properties that block nonspecific binding to lipid-coated surfaces, provide a powerful toolbox for nanotechnology. This review discusses the progress in the emerging field of lipid nanotechnology.
