Trying to lose weight? Try cold herbal tea!

A warm cuppa is already known to aid weight loss.

But drinking tea cold could be even more effective in helping you beat the bulge, research suggests.

Swiss scientists have discovered a cold herbal cuppa helps to burn calories much more than the usual hot version.

The Fribourg researchers scrapped the usual cuppa and investigated the effects of drinking tea made with yerba mate leaves.

The team of researchers found, on average, there was an 8.3% increase in energy expenditure after drinking the cold tea. In comparison, hot tea produced a 3.7% boost.

Fasting for 24 hours regenerates stem cells, study finds

A new study points to one reason fasting may be good for our bodies, with evidence that a 24-hour gap in eating can flick a metabolic switch for regeneration in our digestive system.

By studying the effects of fasting on mice, a team of researchers at MIT found that just one day of calorie restriction substantially improves the ability for stem cells in the intestine to regenerate.

In the fasting mice, however, cells began to break down fatty acids instead of glucose. This stimulated the stem cells to become more regenerative.

“This study provided evidence that fasting induces a metabolic switch in the intestinal stem cells, from utilising carbohydrates to burning fat,” says David Sabatini, an MIT professor of biology and senior author of the paper, published in Cell Stem Cell.


Just living close to livestock might lower allergy risk

Exposure to farms seems to reduce the risk of allergy sensitivity, even among adults, and living close to a livestock farm in particular might curb common allergies, a Dutch study suggests.

Based on more than 2,400 adults in the Netherlands, researchers found that people who lived within 327 meters (1,073 feet) of a farm, but were not farmers themselves, were about 21 percent less likely to experience a range of allergies compared to those living 500 m (1,640 ft) away or more.

The results were similar when researchers looked specifically at proximity to cattle or pig farms, though not for poultry farms. The apparent protection was also seen among people without allergy symptoms, but whose blood test showed a tendency to have an immune reaction associated with common allergies, food allergies, asthma and eczema.

"For 20 years, a large number of studies have shown that allergies are less prevalent in farmers and farmers' children," said senior study author Lidwien Smit of Utrecht University.

Doctors do not always explain sexual side effects of prostate treatments

Medications that treat lower urinary tract symptoms and enlarged prostates may cause sexual dysfunction, but some urologists do not discuss this with patients, according to a survey of doctors.

Although more than half of the physicians said they discuss ejaculatory dysfunction when prescribing the most common treatments, most do not routinely offer alternatives, the study authors report in World Journal of Urology.

"We need to think about the entire picture as doctors. Even if patients are 100% satisfied with the treatment and can urinate perfectly, they may be unhappy that they can't ejaculate anymore," said lead study author Dr. Simone Giona of King's College Hospital in London.

Lower urinary tract symptoms and prostatic hyperplasia - an enlarged prostate - cause difficulty with urination, urgency and leaking. Patients sometimes wait until symptoms worsen before seeking treatment, often because they know treatments could affect sexual function, Giona said.

Marriage may be good for catching melanoma early

Compared to married patients, widows were 70 percent more likely to have early-stage melanoma diagnosed when it was thicker and harder to treat, while divorced people were 38 percent more likely to get diagnosed later and never-married individuals had 32 percent higher odds, the study team reports in JAMA Dermatology.

"We suspect that part of the reason that married patients present with earlier-stage melanoma is from having another pair of eyes on their skin that allows for identification of suspicious lesions," said lead author Cimarron Sharon of the Hospital of the University of Pennsylvania in Philadelphia.

"People in long-term relationships see their partner's skin frequently over time, and are able to notice any new or changing lesions, especially in difficult to see areas, such as the back," Sharon said by email.

Married people may be more likely to spot a deadly skin cancer sooner than their counterparts who aren't part of a couple, a U.S. study of melanoma patients suggests.

My 2 cents:
I have successful removed black spots and melanoma by using tiger balm ointment (red label, which is the stronger type). But there is a side-effect.

After applying for a few days, your skin will be very itchy. It is ok to scratch the itchy part (this is how your body wants you to remove the spots) but remember to cut your finger nails as long finger nails will cause bleeding to your skin.
