Flowers’ smell really can soothe stress

Wondering how to de-stress yourself? Well, then try savour the smell of flowers, lemon or mango, for a new study has revealed that inhaling certain fragrances alter gene activity and blood chemistry in ways that can reduce stress levels.

According to lead researcher Akio Nakamura, people have inhaled the scent of certain plants since ancient times to help reduce stress, fight inflammation and depression, and induce sleep.

Aromatherapy, the use of fragrant plant oils to improve mood and health, has become a popular form of alternative medicine today.

And linalool is one of the most widely used substances to soothe away emotional stress.

During the study, the scientists exposed lab rats to stressful conditions while inhaling and not inhaling linalool.

The findings showed that linalool returned stress-elevated levels of neutrophils and lymphocytes — key parts of the immune system — to near-normal levels.

Inhaling linalool also reduced the activity of more than 100 genes that go into overdrive in stressful situations.

The researchers hope that the findings could form the basis of new blood tests for identifying fragrances that can soothe stress.

The study appears in ACS' Journal of Agricultural and Food Chemistry, a bi-weekly publication. - Indian Express

Yogurt can help lose excess weight

Taking probiotics after Roux-en-Y gastric bypass surgery can help obese patients to lose weight more quickly, according to a new study. Probiotics are the so-called ‘good’ bacteria found in yogurt as well as in over-the-counter dietary supplements that help in the digestion of food.

New research from the Stanford University School of Medicine and Stanford Hospital & Clinics suggests that patients who take probiotics after the gastric-bypass procedure tend to shed more pounds than those who don't take the supplements.

"Surprisingly, the probiotic group attained a significantly greater percent of excess weight loss than that of control group," said John Morton, MD, associate professor of surgery at the medical school who wrote the paper with lead author Gavitt Woodard, a third-year medical student, and five other medical students at the Surgery Center for Outcomes Research and Evaluation in Stanford''s Department of Surgery.

The researchers followed 44 patients on whom Morton had performed the procedure from 2006 to 2007. Patients were randomized into either a probiotic or a control group. Both groups received the same bariatric medical care and nutritional counseling, as well as the support of weight-loss study groups. Both groups also were allowed to consume yogurt, a natural source of probiotics.

In addition, the probiotic group consumed one pill per day of Puritan''s Pride, a probiotic supplement that is available online and in many stores. Morton has no financial ties to the company that makes the supplement. The study showed that at three months, the probiotics group registered a 47.6 percent weight loss, compared with a 38.5 percent for the control group.

The study also found that levels of vitamin B-12 were higher in the patients taking probiotics — a significant finding because patients often are deficient in B-12 after gastric-bypass surgery. The probiotics group had B-12 levels of 1,214 picograms per milliliter at three months, compared with the control group''s levels of 811 pg/mL. Morton said he now recommends probiotic supplements to his patients, and he plans to continue to look for ways to enhance the outcomes from the procedure.

High insulin levels enhance breast cancer risk

Elevated insulin levels in the blood seem to raise the risk of breast cancer in post-menopausal women, according to a new study.

Increased breast cancer risk for post-menopausal women has previously been linked to obesity and diabetes. Both conditions involve insulin resistance, which causes increases in circulating levels of insulin.

Since insulin is known to promote cell division and enhance breast tumour growth in animal models, Einstein College of Medicine scientists reasoned that relatively high insulin levels may contribute to breast cancer risk in women.

"Up to now, only a few studies have directly investigated whether insulin levels are associated with breast cancer risk, and those studies have yielded conflicting results," says Geoffrey Geoffrey Kabat, senior epidemiologist at Einstein and the study's co-author.

"Those other studies were based on just a single baseline measurement of insulin, while our study involved analysing repeated measurements of insulin taken over several years - which provides a more accurate picture of the possible association between insulin levels and breast cancer risk."

Kabat and colleagues analysed data on 5,450 women enrolled in the Women’s Health Initiative, a large multi-centre study investigating the influence of a number of factors on women's health.

Most of the women had participated in the clinical trial part of the study and provided fasting blood samples at its start (baseline) and then at years one, three and six.

The remaining women, who were enrolled in a separate "observational" component of the study, provided fasting blood samples at baseline and at year three of the study. Among all these women, 190 cases of breast cancer were identified over eight years of follow-up.

The analysis revealed a strong association between elevated insulin levels and increased risk for breast cancer, said an Einstein release. These findings were published in online in the International Journal of Cancer. –The Times of India

Adopt a proper diet 'to control diabetes'

Good morning friends. Balance diet must require for those people who have diabetes. We can control it with a proper diet. As most of the people always wanted to eat, people with diabetes should be aware of all the food they will going to eat.

Suffering from diabetes? Fret not, just adopt a proper and healthy diet, for a new study has revealed that using lifestyle interventions on top of existing drug treatments can help controlling high blood sugar levels.

A team at University of Otago has provided intensive dietary advice to improve blood sugar control in diabetics -- even though they're on what is regarded as the best available medication.

The study divided 87 high-risk diabetes patients into two groups. Both received optimized medical care, but patients in one of the groups also received regular one-on-one dietary advice from a dietitian.

Lead investigator Dr Kirsten Coppell said that at the end of the study, measures of glycaemic control were found to have significantly improved in the group receiving the advice. The group also recorded an average weight loss of 2 kg and a 3cm reduction in waistlines.

"Achieving good glycaemic control is a crucial goal in managing diabetes, as it can prevent long-term complications such as kidney failure, heart disease and blindness. Before the widespread introduction of anti-diabetic drugs, the key focus in diabetes care was on diet and lifestyle.

"Our research indicates that while this earlier approach has tended to be forgotten in this modern age of a 'pill for every ill', it still very much has its place in diabetes management," Dr Coppell said. – The Times of India
