Tips to keeping your teeth white
|
view preview
Whitening treatments do not permanently whiten teeth. If you expose your teeth to foods and beverages that cause staining you may see the whiteness start to fade in as little as one month after treatment. Those who avoid foods and beverages that stain may be able to wait one year or longer before another whitening treatment or touch-up is needed. You worked hard to get your teeth white. Here are some tips to help maintain your pearly whites. - Avoid the consumption of or exposure to products that stain your teeth, such as coffee, tea, and red wine. If you do choose to consume beverages that stain, consider using a straw so that the liquid bypasses your front teeth.
- Brush or rinse immediately after consuming stain-causing beverages or foods.
- Fo

Could dietary salt be the reason for increased incidences of autoimmune diseases?
|
view preview
Researchers at Yale School of Medicine, Harvard Medical School and the Broad Institute have identified a prime suspect in the mystery of an increased incidence of autoimmune diseases in the past few decades—dietary salt. In the paper, researchers showed that salt can induce and worsen pathogenic immune system responses in mice and that the response is regulated by genes already implicated in a variety of autoimmune diseases.

Who needs supplements when you have kiwis?
|
view preview
Researchers from University of Otago have found that a natural fruit source of vitamin C – kiwifruit – is vastly superior to a purified supplement form. The researchers are studying kiwifruit as a source of dietary vitamin C and found that in mice eating kiwifruit, vitamin C uptake was five times as effective as taking a purified supplement form. The study was recently published in the American Journal of Clinical Nutrition, the highest ranking journal for human nutrition research. ...

Try dates, not honey
|
view preview
While they are super sweet, syrup made from this ancient fruit has antibacterial compounds that are more effective than honey. In case you've never had it or seen it before, dates are a thick, dark brown, and super-sweet fruit used in Middle Eastern cuisine. New research suggests that date syrup contains chemical compounds that help ward off a number of bacterial infections, including those caused by Staphylococcus aureus and Escherichia coli. This was discovered after scientists inhibited the growth of these pathogens for about six hours, which researchers say is faster than manuka honey - a honey known for its antibacterial and wound healing properties. ...

E-cigarettes - not as evil as we thought
|
view preview
According to a new report published out of the UK, E-cigarettes are 95% less harmful to your health than normal cigarettes. When supported by a smoking cessation service, they help most smokers to quit tobacco altogether. They have also concluded that there is "no evidence" that they offer young people a gateway into smoking. In fact, the review suggests that e-cigarettes may be contributing to falling smoking rates in the U.K., as 2.6 million adults are now thought to be using the product. They also found that almost all of these adults are ex-smokers, providing evidence that many people are not starting to use the devices after having never smoked in the first place, and instead are using them to either quit or cut down on tobacco. ...

This peanut butter is a health hazard
|
view preview
I was shopping around in Michigan a few weeks ago when I stumbled upon this product proudly made by the Velvet Peanut Butter Company. I was appalled when I read that it's made from Fully Hydrogenated Vegetable Oil, while the trans-fat count is at zero grams - a very misleading claim. This product is literally poisonous for human consumption, yet it is prepared for young children and people of lower socioeconomic status, given its low price tag. Hydrogenated oil is scientifically known to increase LDL 'bad' cholesterol and lower HDL 'good' cholesterol, thereby leading to heart disease and cancer. It should be against the law to feed it to kids. In the United States, labelling a product trans-fat free doesn't necessarily mean it doesn't conta ...

Watch these white blood cells destroy this roundworm
|
view preview
White bloods cells, known scientifically as leukocytes, are immune system cells that fight infect. The immune system is made up of a network of cells, tissues, and organs that work together to protect the body. Sometimes our bodies encounter pathogens like bacteria, or in this case a parasitic worm. Roundworms, or nematodes, are parasites that can infect people by living and feeding in the intestines. There are different kinds of worms that can cause infection, and they can range in length from 1 millimeter to 1 meter. Luckily, this worm was no challenge for these hungry white blood cells. ...

Addicted to hookah smoking, this might change your mind
|
view preview
As cigarette smoking rates fall, more people are smoking tobacco from hookahs: communal pipes that enable users to draw tobacco smoke through water. A new meta-analysis shows that hookah smokers are inhaling a large load of toxicants. According to the study, compared with a single cigarette, one hookah session delivers approximately 125 times the smoke, 25 times the tar, 2.5 times the nicotine and 10 times the carbon monoxide (CO). The latter stat accounts for the light-headedness and high that smokers experience when inhaling the smoke, since CO reduces the amount oxygen capable of binding to circulating red blood cells. In addition to these estimates, the Centers for Disease Control and Prevention recently reported that, for the first time ...

Running reduces tumor size in mice by 50%
|
view preview
According to a new study published in Cell Metabolism, mice who spent their free time on a running wheel were better able to shrink tumors (a 50 percent reduction in tumor size) compared to their less active counterparts. Researchers found that the surge of adrenaline ( epinephrine) that comes with a high-intensity workout helped to move cancer-killing immune (NK) cells toward lung, liver, or skin tumors implanted into the mice. While the research is hopeful for patients looking for inexpensive ways to manage their cancer, more needs to be learned about the effects of exercise on metastasis and longevity, as well as if the observations hold true in humans. Scientists also wants to explore the combined impact of anti-cancer treatments and ex ...

Living without a heart
|
view preview
Stan Larkin (pictured on the right), who's now 25, was diagnosed with familial cardiomyopathy. This form of disease results in the heart having difficulty pumping enough blood through the body. Faced with a lack of compatible heart donors, Stan underwent an operation in 2014 to remove his failing heart and replace it with an external total artificial heart, dubbed the Freedom portable driver. This battery-powered device uses compressed air to pump blood around the body in the same way a heart does, and as the name suggests, it is portable and only weighs 6 kilograms (13 pounds). The device does an incredible job at keeping the patient in a healthy condition while a donor heart becomes available, but it isn’t considered a long-term option. ...
