Search for better biofuels microbes leads to human gut

Scientists have scoured cow rumens and termite guts for microbes that can efficiently break down plant cell walls for the production of next-generation biofuels, but some of the best microbial candidates actually may reside in the human lower intestine, researchers report. Continue reading

Reduced energy density in foods can create healthier food environment, may help to reduce obesity

Reduced energy density in foods can create healthier food environment, may help to reduce obesity

On the heels of new research showing that 16 major food and beverage companies have collectively cut 6.4 trillion calories from U.S. food products, The Obesity Society (TOS) issues an official position statement pointing to the pervasive availability of foods high in calories per unit of weight, or energy density, as a contributing factor for weight gain and obesity. The Society goes further to urge food companies to test and market foods that will help individuals reduce the energy density in their diets and better manage body weight. Continue reading

Comparison of named diet programs finds little difference in weight loss outcomes

Comparison of named diet programs finds little difference in weight loss outcomes

In an analysis of data from nearly 50 trials including about 7,300 individuals, significant weight loss was observed with any low-carbohydrate or low-fat diet, with weight loss differences between diet programs small, findings that support the practice of recommending any diet that a patient will adhere to in order to lose weight, according to a study in the September 3 issue of JAMA . Named or branded (trade-marked) weight loss programs provide structured dietary and lifestyle recommendations via popular books and in-person or online behavioral support and represent a multibillion dollar industry. Debate regarding the relative merit of the diets is accompanied by advertising claiming which macronutrient composition is superior, such as a low-carbohydrate or low-fat diet. Continue reading

Training your brain to prefer healthy foods

Training your brain to prefer healthy foods

It may be possible to train the brain to prefer healthy low-calorie foods over unhealthy higher-calorie foods, according to new research by scientists at the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University and at Massachusetts General Hospital. Published online today in the journal Nutrition & Diabetes , a brain scan study in adult men and women suggests that it is possible to reverse the addictive power of unhealthy food while also increasing preference for healthy foods. “We don’t start out in life loving French fries and hating, for example, whole wheat pasta,” said senior and co-corresponding author Susan B Continue reading

Lead linked to obesity in mice exposed by mothers

When we think of ill effects from lead exposure various neurologic problems usually come to mind. Now researchers at the University of Michigan say another health impact can be added to the list: obesity. Continue reading

Wake-up call for more research into cell metabolism

Wake-up call for more research into cell metabolism

More scientific research into the metabolism of stromal support cells and immune cells — and the role of the metabolism of these cell types in the development of diseases — could open new therapeutic avenues for diabetes, inflammatory conditions and cancer. That was the conclusion of a review article by scientists from VIB and KU Leuven in the leading journal Nature Continue reading

New discovery in living cell signaling

New discovery in living cell signaling

A breakthrough discovery into how living cells process and respond to chemical information could help advance the development of treatments for a large number of cancers and other cellular disorders that have been resistant to therapy. An international collaboration of researchers, led by scientists with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley, have unlocked the secret behind the activation of the Ras family of proteins, one of the most important components of cellular signaling networks in biology and major drivers of cancers that are among the most difficult to treat Continue reading
