(Press-News.org) In a large prospective study published online in the European Journal of Clinical Nutrition*, researchers looked at the association between nut consumption and risk of colorectal cancer among 75,680 women in the Nurses' Health Study, with no previous history of cancer.
Women who consumed a one-ounce serving of nuts, including tree nuts (such as almonds, Brazil nuts, cashews, hazelnuts, macadamias, pecans, pine nuts, pistachios and walnuts), two or more times per week had a 13% lower risk of colorectal cancer (RR, 0.87; 95% CI, 0.72-1.05; P=0.06) compared to those who rarely consumed nuts. "While this association was not statistically significant," stated lead researcher, Ying Bao, MD, ScD, from the Department of Medicine, Brigham and Women's Hospital and Harvard Medical School, Boston, MA, "a possible inverse association was suggested and this has been observed in previous prospective studies as well."
The current study is the most comprehensive study to date looking at long-term nut consumption and colorectal cancer risk and the one with the longest follow-up of 30 years. Colorectal cancer is the second most common cancer in women and the third most common cancer in men worldwide. Risk of colorectal cancer is higher among individuals with excess body weight, and type 2 diabetes. Interestingly, women in this study who consumed the most nuts tended to be leaner. According to Dr. Bao, "Since nuts have been associated with less weight gain and a decreased risk of type 2 diabetes, increasing nut consumption may result in reduced risk of developing colorectal cancer."
Previous research has shown that women in this same cohort, who consumed a one-ounce serving of nuts two or more times per week, had a significantly reduced risk of pancreatic cancer (RR, 0.65; 95% CI, 0.47-0.92; P=0.007) compared to those who largely abstained from nuts.** "These findings are very encouraging," stated Maureen Ternus, M.S., R.D., Executive Director of the International Tree Nut Council Nutrition Research & Education Foundation (INC NREF). "While we've known for years that 1.5 ounces (or 1/3 cup) of nuts per day can help reduce the risk of heart disease, more and more research is showing the potential beneficial effect of nut consumption on other chronic diseases such as diabetes and cancer."

On 9 May we celebrate Europe Day. On this 65th anniversary of the Schuman Declaration 85% of Flemish adolescents and 80% of the adults feel European. 62% of the respondents also feel actively involved in what happens in the European Union. That is the conclusion of a study by the KU Leuven Centre for Political Research.
"I consider myself an EU citizen" and "I am proud to be living in Europe". These are just some of the statements that Soetkin Verhaegen presented to almost 3600 fifteen-year-olds and their parents (of whom over 4300 participated). She found that a surprisingly ...
LAWRENCE -- The cliché version of the American dream usually involves getting married, finding a good job, raising 2.5 kids and buying a home with a white picket fence.
But in recent times spiking prices can make home ownership impossible -- or falling prices can trap homeowners in so-called "upside-down" mortgages, where debt dwarfs the shrinking value of a house.
"To determine the right price of a house, people need to make long-term projections of many uncertain economic variables, such as interest rate," said Shu Wu, associate professor of economics at the ...
ANN ARBOR -- Arginine, a common amino acid found naturally in foods, breaks down dental plaque, which could help millions of people avoid cavities and gum disease, researchers at the University of Michigan and Newcastle University have discovered.
Alexander Rickard, assistant professor of epidemiology at the U-M School of Public Health, and colleagues, discovered that in the lab L-arginine -- found in red meat, poultry, fish and dairy products, and is already used in dental products for tooth sensitivity--stopped the formation of dental plaque.
"This is important ...
TORONTO, May 7, 2015 -- Highly priced cancer drugs get rushed approvals despite poor trial methodology and little effect on the longevity of patients, cautions York University Professor Dr. Joel Lexchin in the School of Health Policy and Management.
"Patients and their doctors should demand that regulators require pharma companies to provide clear evidence of clinical effectiveness of the drugs, resulting from rigorous methodology," suggests Lexchin. "Drug agencies like the Food and Drug Administration (FDA) and the European Medicine Agency (EMA) don't actually look at ...
Compliance with post-treatment surveillance, income level and the travel distance for follow-up care had effects on survival in patients with head and neck squamous cell cancer (HNSCC), according to a report published online by JAMA Otolaryngology-Head & Neck Surgery.
Post-treatment surveillance is a key component for patients with HNSCC, a cancer with a five-year survival rate of only slightly above 50 percent. The National Comprehensive Cancer Network guidelines recommend follow-up should consist of visits at least every one to three months during the first year after ...
The use of cholesterol-lowering statins when men initiated androgen deprivation therapy for prostate cancer was associated with longer time to progression of the disease, according to an article published online by JAMA Oncology.
The gene SLCO2B1 acts as a transporter that enables a variety of drugs and hormones to enter cells. For example, dehydroepiandrosterone sulfate (DHEAS) is a precursor of testosterone and uses SLCO2B1 to get into cells. Similarly, statins use SLCO2B1 to enter cells as well. Previous research has suggested an association between statin use and ...
Crigler-Najjar syndrome is a rare autosomal recessive disorder caused by mutations in the UGT1A1 gene, which result in the toxic accumulation of bilirubin, a substance made by the liver in the body. Indeed, when the UDP-glucuronosyltransferase 1 isotype A1 (UGT1A1), the enzyme responsible for removing bilirubin, doesn't work, the substance accumulates, causing a severe and chronic jaundice, and becoming toxic for the brain and leading to lethality.
Gene therapy has allowed the restoration of an equivalent level of bilirubin to those found in healthy animals

This news release is available in French. Metabolic complications of obesity and overweight, such as type 2 diabetes, are an important challenge to public health. Teams led by Nicolas Venteclef, Inserm Research Fellow (Cordeliers Research Centre, Inserm/Pierre and Marie Curie University Joint Research Unit 1138, Paris, France) and Irina Udalova (Kennedy Institute of Rheumatology, University of Oxford, UK) in collaboration with several teams, have succeeded in elucidating part of the mechanisms involved in the development of these metabolic complications associated with ...
Obesity and depression -- not only lack of sleep -- are underlying causes for regular drowsiness, according to Penn State College of Medicine researchers. They say these findings could lead to more personalized sleep medicine for those with excessive daytime sleepiness (EDS).
As much as 30 percent of the general population experiences EDS -- daytime drowsiness or sleepiness occurring throughout the day that can include irresistible sleep attacks. Feeling overly tired during the day can reduce job productivity and increase errors and absenteeism and may lead to more serious ...
A new, noninvasive nuclear medicine test can be used to determine whether aromatase inhibitor treatment will be effective for specific cancer patients, according to a recent study reported in The Journal of Nuclear Medicine. The research shows that a PET scan with the ligand C-11-vorozole reliably detects aromatase in all body organs - demonstrating the value of its future use to pre-determine the effectiveness of the treatment for breast, ovarian, endometrial and lung cancer patients, potentially reducing unnecessary treatment costs and adverse effects.
Aromatase inhibitors ...
