Even healthy people carry viruses in their bodies!

On an average, healthy individuals carry about five types of viruses in their bodies and the same viruses that make us sick can take up residence in and on the human body without provoking a sneeze, cough or other troublesome symptom, says a significant study.

Even healthy people carry viruses in their bodies!

“Lots of people have asked whether there is a viral counterpart (to bacterial flora) and we have not had a clear answer. But now we know there is a normal viral flora and it is rich and complex,” said study co-author Gregory Storch from the Washington University School of Medicine in St Louis. In 102 healthy young adults aged 18 to 40, researchers sampled five body habitats: nose, skin, mouth, stool and vagina.

At least one virus was detected in 92 percent of the people sampled and some individuals harboured 10 to 15 viruses. Analyzing the samples, scientists found seven families of viruses, including strains of the herpes virus that are not sexually transmitted. Strains of papillomavirus were found in about 75 percent of skin samples and 50 percent of samples from the nose.

Not surprisingly, the vagina was dominated by papillomaviruses with 38 percent of female subjects them.  Some of the women harboured certain high-risk strains that increase the risk of cervical cancer. Adenovirus, the virus that cause the common cold and pneumonia, also was common at many sites in the body. It is possible that some of the viruses the researchers uncovered were latent infections acquired years ago.

“But many viruses were found in body secretions where the presence of a virus is an indicator of an active infection. Dormant or latent viruses hide in cells, not in body fluids such as saliva or nasal secretions,” added lead author Kristine M. Wylie, an instructor of paediatrics.

According to researchers, it is very important to know what viruses are present in a person without causing a problem and what viruses could be responsible for serious illnesses that need medical attention.

The study appeared online in the journal BioMed Central Biology.

7 Reasons Vegetarians Live Longer

There’s nothing wrong with eating meat if you’re doing so in moderation (I for one, will never give up the occasional cheeseburger), but research does show that vegetarians tend to be healthier overall, and even live longer.

Now there’s another health perk vegetarians can boast about. A new study published in the journal JAMA Internal Medicine looked at data from seven clinical studies and 32 other studies published between 1900 and 2013 where participants kept a vegetarian diet and found that vegetarians have lower blood pressure compared to people who eat meat.

Here are some other reasons vegetarians may outlive meat-lovers.

1. Low blood pressure: In the latest study, researchers found that not only do vegetarians have lower blood pressure on average, but that vegetarian diets could be used to lower blood pressure among people who need an intervention.

2. Lower risk of death: A 2013 study of more than 70,000 people found that vegetarians had a 12% lower risk of death compared with non-vegetarians. With none of the saturated fat and cholesterol that clogs arteries, vegetarians may be at a lower risk for chronic diseases overall.

3. Better moods: A 2012 study randomly split participants into a three diets: all-meat allowed, fish-only, and vegetarian no-meat. The researchers found that after two weeks, the people on the vegetarian diet reported more mood improvements than those on the other two diets.

4. Less chance of heart disease: Another 2013 study of 44,000 people reported that vegetarians were 32% less likely to develop ischemic heart disease.

5. Lower risk of cancer: Researchers at Loma Linda University in California studied different versions of the vegetarian diet and cancer risk among people at a low risk for cancer overall and discovered that a vegetarian diet may have protective benefits. Although the study is not the final say on the matter, vegans had the lowest risk for cancers, specifically cancers most common among women, like breast cancer.

6. Lower risk of diabetes: Studies have shown that vegetarians are at a lower risk for developing diabetes. While the diet won’t cure the disease, it can lower an individual’s risk by helping them maintain weight and improve blood sugar control.

7. Less likely to be overweight: Research shows that vegetarians tend to be leaner than their meat-eating counterparts, and that they also tend to have lower cholesterol and body mass index (BMI). Some data suggests that a vegetarian diet can help with weight loss and be better for maintaining a healthy weight over time.

People who don’t eat vegetarian can still be very healthy, and a vegetarian diet comes with its own health risks. For instance, research has also shown that vegetarians are at a higher risk for iron deficiencies, and some experts question whether children who are raised vegetarian get the right amount of nutrients for their growing bodies. Making sure you get the right amount of nutrients is important, and keeping your physician in the loop about your eating habits can make sure you’re meeting all the requirements for good health.
