Researchers analyzed dental plaque from skeletons in a medieval cemetery in Germany and found that the mouths of these aged humans were home to many of the same bacterial invaders that cause gum disease in the mouths of modern humans.
We knew that calculus preserved microscopic particles of food and other debris but the level of preservation of biomolecules is remarkable a microbiome entombed
The team reconstructed the genome of a major bacterial pathogen and recovered some of the first evidence of food molecules from ancient dental plaque.
and many of them showed signs of gum disease and tooth decay. While a few individuals had surprisingly healthy teeth most of the older adults had lost most or all of their teeth due to wearing decay or dental disease.
The microbe species found in the ancient plaque were remarkably similar to ones found in modern mouths the researchers said.
Gum disease is caused most often by the species Porphyromonas gingivalis Tannerella forsythiatreponema denticola and Filifactor alocis and these microbes were all present on the teeth of the skeletons with dental disease.
Gum diseases are caused usually by infections or inflammation of the gums and surrounding bone. About 47 percent of adults ages 30 or older in the United states have some form of gum disease according to the Centers for Disease Control and Prevention.
Nonhuman primates and other wild animals rarely get dental diseases Warinner said which raises the question What is it about humans that allows these pathogens to grow?
Scientists speculate that modern human diets and lifestyles may be to blame but Warinner's team plans to analyze more ancient populations from other time periods to find out.

Very early studies indicate whey protein may have a role in the body's cancer-fighting abilities.
Whey protein is said also to help control blood sugar lower cholesterol treat asthma and possibly prevent allergies.
Do whey protein supplements work? Whey protein supplements can certainly provide high-quality protein in the diet.
But most health organizations including the Centers for Disease Control and Prevention recommend getting your protein from food
The members of the group taking protein supplements were also less likely to visit doctors for infections during the study published in 2003 in the Journal of Applied Physiology.
because whey protein has a high level of leucine an easily absorbed amino acid according to Joslin Diabetes Center.
People with HIV liver disease diabetes and various cancers can all develop low glutathione levels in the body.

and very preliminary evidence that whey protein may help lower high blood pressure. Whey protein also shows a potential for lowering blood sugar.
A study of 14 people with type 2 diabetes found that combining whey protein with a high-sugar meal increased people's insulin production
and osteoporosis. That's because acids are released into the bloodstream when protein is digested and the body uses calcium to neutralize these acids.
Some research shows high-protein diets are correlated with more fractures but other research has found people with high-protein diets have increased bone density according to the Harvard School of Public health.
Because whey is a dairy product people with milk allergies should avoid whey protein. People who are lactose intolerant should also take caution.
Whey protein supplements can decrease the effectiveness of the Parkinson's drug levodopa. Whey protein supplements may also reduce how much of the osteoporosis drug alendronate is absorbed by the body making the medicine less effective.
Whey protein supplements may reduce the effectiveness of quinolone and tetracycline antibiotics. People with diabetes may experience changes in blood sugar when taking protein supplements.
It is best to talk to your doctor about your athletic goals and personal needs before starting protein supplements.

#It Takes A lot More than Carrots to Beat Cancer (Op-Ed) This article was published originally at The Conversation.
Another story about how some food holds the cure for cancer is making headlines in the Daily Express.
In March the Daily mail claimed that eating carrots is a way to avoid prostate cancer.
and vegetables is associated with a reduced risk of a variety of cancers. But the charity organisation Cancer Research UK stresses the link between diet
and cancer is complex and difficult to unravel#.#That is an important caveat. There is little chance that the key to preventing one of the world s deadliest diseases has been on our dinner plates the whole time.
The lead researcher of the new study Dr. Kirsten Brandt at Newcastle University has been studying naturally occurring chemicals found in certain vegetables called polyacetylenes for many years.
They have been shown to kill leukaemia cells in the laboratory. And a compound which can be extracted easily from something as common and cheap as carrots is bound to arouse interest.
This however is only the first step in testing any potential new anticancer chemicals. In their study Brandt and her colleagues also used a mouse model as proxy for humans
which has a genetic mutation that increases the chances of developing intestinal cancer. Mice fed a diet where a fifth of the food was powdered carrot had fewer and smaller tumours than mice who were fed a normal diet.
The scientists will now look to see if this tumour-preventing effect is seen also in people by doing a small-scale study involving 20 participants.
This if successful will have to be followed up by even larger scale trials before carrots can be considered beneficial in cancer prevention.
Sarah Warner a Phd student in Brandt s research group described her project to me.
whether a portion of carrots consumed per day can affect the risk of someone developing a chronic disease by looking at DNA damage
and biomarkers related to intestinal cancer#she said. All cancers are a result of damaged DNA.
So commonly consumed foods that reduce this damage could be a significant step in preventing cancer especially in individuals who have a genetic predisposition to the disease.
But the current results do not imply that they hold the key to beating cancer#.
#What is perhaps more interesting is that the preparation of the carrots influences how much polyacetylene actually gets from the food into our bodies.
Sarah hopes that contrasting these two varieties of carrots may allow the research team to pinpoint the chemicals that are responsible for their early cancer-protective findings
and it may lead to great advances in the fight against cancer the researchers are not making that claim just yet.

The American Institute for Cancer Research recommends eating lots of fruits and vegetables including apples. The antioxidant content of apples ranks among the highest for fruits and research shows that antioxidants help prevent cancer.
Lung cancer risk can especially be lowered through apples'antioxidants according to Flores. A study in Hawaii found that people who regularly eat apples onions
and white grapefruit cut their lung cancer risk in half. Eating apples in excess will not cause many side effects said Flores.
But as with anything eaten in excess apples may contribute to weight gain. Furthermore apples are acidic

#Food safety Returns To Nature (ISNS) Outbreaks of foodborne diseases carried by bacteria can be a nuisance at best and deadly at worst.
One way to destroy these pathogens is with more pathogens. Bacteriophages are viruses that specifically attack bacteria.

#oe Phages are not human pathogens. The bacteria are the human pathogens#said Paul Ebner a professor of animal sciences at Purdue

Researchers are also looking into ways to treat bacterial infections in livestock using phages but Sulakvelidze said that results from these tests are inconclusive so far.
Antibiotic resistance in bacteria is a crisis. According to the Centers for Disease Control and Prevention each year in the United states at least two million people become infected with bacteria that are resistant to antibiotics
and at least 23000 people die each year as a direct result of these infections.##Phages are a hopeful alternative.

Eating avocados may also lower the risk of heart disease. High levels of homocysteine is associated with a higher risk of heart disease
but the Vitamin b6 and the folic acid found in avocados can help regulate it. One seven-year study published in 2013 found that avocados were associated with a reduced risk of metabolic syndrome

Bananas'high potassium and low sodium content may also help protect your cardiovascular system against high blood pressure according to the FDA.
Vitamin b6 can also help protect against type 2 diabetes and aid in weight loss according to Flores.
Some evidence suggests that moderate consumption of bananas may be protective against kidney cancer. A 2005 Swedish study found that women who ate more than 75 servings of fruits
and vegetables cut their risk of kidney cancer by 40 percent and that bananas were especially effective.
Women eating four to six bananas a week halved their risk of developing kidney cancer.
Bananas may be helpful in preventing kidney cancer because of their high levels of antioxidant phenolic compounds.
However eating the fruits in excess may trigger headaches and sleepiness Flores said. She said that such headaches are caused by the amino acids in bananas that dilate blood vessels.
Overripe bananas contain more of these amino acids than other bananas. Bananas can also contribute to sleepiness
which is characterized by muscle weakness temporary paralysis and an irregular heartbeat. It can have serious consequences
Another potentially significant answer in the long-running mystery behind colony collapse disorder (CCD) may have emerged just:
the scientists found a viral pathogen that typically infects plants spreading inside the bees. The detection of this virus (the Tobacco Ringspot Virus or TRSV) could help explain the decline of honeybees
whether this plant-infecting virus could also cause systemic infection in the bees said Yan Ping Chen a study author who works at ARS.
and that the infection becomes widespread in their bodies said Ji Lian Li another study author who works at China's agricultural science academy in Beijing.
and whether such a virus could cause systemic infection in the honeybees. Since CCD was reported first to have wiped out entire hives across the United states in 2006 and 2007 more than 10 million hives in all researchers have linked strongly toxic viral cocktails to the collapse of the honeybee colonies.
Besides TRSV researchers have linked Israel Acute Paralysis Virus Acute Bee Paralysis Virus Chronic Paralysis Virus Kashmir Bee Virus Deformed Wing Bee Virus
Black Queen Cell Virus and Sacbrood Virus to some degree as causes of honeybee viral disease.
In fact as I wrote last August researchers in the past year have begun to focus on multiple layers of viral infection
or chemical contamination as the most likely reason for CCD. In short waves of either chemical contamination
or viral infections are overwhelming the honeybees and the hives. Last summer for instance researchers from the University of Maryland and the USDA collected pollen from seven major types of crops along the East Coast where CCD has been especially destructive where bees had been in serious decline and fed
them to healthy bees. The pollen fed to the healthy bees contained an average of nine different types of pesticides and fungicides.
because it lacks an internal genomic process that edits out errors in replicated genomes meaning that TRSV can generate all sorts of variant error-filled copies with lots of different infection characteristics that cannot be defended easily once they jump from plants to honeybees and spread throughout the hives.
which these error-filled virus copies become a sort of cloud of genetically-related variants that seemingly work in concert to determine the pathology of their hosts.
and reemerging infectious diseases the researchers said in their mbio study. What is becoming clear the U s
. and Chinese researchers said is that such clouds of viral infections in colonies are likely responsible for the collapse of hives.
Weak colonies those with high levels of multiple viral infections start failing in late fall
and supports the view that viral infections have a significant negative impact on colony survival the U s
