Obesity inhibits key cancer defense mechanism

Thu, 26 Apr 18 00:16:10 -0700

Obesity could enhance cancer development while aspirin might prevent it -- a new insight into potential targets for cancer prevention.

Bacteria in the small intestine indispensable for fat absorption

Thu, 26 Apr 18 00:09:00 -0700

A researcher at Midwestern University led a new study showing that Western diets, high in fat and simple sugar, promote the growth of bacteria in the small intestine that increase fat digestion and absorption. The goals of the study were to determine if microbes were required for digestion and absorption of fats, to begin to learn which microbes were involved, and to assess the role of diet-induced microbes on the digestion and uptake of fats.

Mediterranean diet boosts beneficial bacteria

Wed, 25 Apr 18 00:00:50 -0700

Here's another reason to eat a Mediterranean-type diet: it's good for your gut. Scientists at Wake Forest Baptist Medical Center found that eating a plant-based diet enhanced the good bacteria living in the gut by up to 7 percent as compared to only 0.5 percent from eating a more meat-centric, Western diet.

What can a tasty milkshake teach us about the genetics of heart disease?

Tue, 24 Apr 18 00:01:30 -0700

Analysis of high-resolution genomic data in a large study population reveals novel low-frequency polymorphisms that drive response to dietary lipids and medication.

Eating more fish could prevent Parkinson's disease

Mon, 23 Apr 18 00:01:00 -0700

Parvalbumin, a protein found in great quantities in several different fish species, has been shown to help prevent the formation of certain protein structures closely associated with Parkinson's disease. A new study from Chalmers University of Technology, Sweden, shines more light on the link between consumption of fish and better long-term neurological health.

Why zero-calorie sweeteners can still lead to diabetes, obesity

Sun, 22 Apr 18 00:15:10 -0700

Increased awareness of the health consequences of eating too much sugar has fueled a dramatic uptick in the consumption of zero-calorie artificial sweeteners in recent decades. However, new research finds sugar replacements can also cause health changes that are linked with diabetes and obesity, suggesting that switching from regular to diet soda may be a case of 'out of the frying pan, into the fire.'

New DNA screening reveals whose blood the vampire bat is drinking

Fri, 20 Apr 18 00:06:00 -0700

The vampire bat prefers to feed on domestic animals such as cows and pigs. When it does so, there is a risk of transmission of pathogens. Now, a new study describes a new DNA method to efficiently screen many vampire bat blood meal and fecal samples with a high success rate and thereby determine which animals the vampire bats have fed on blood from.

Fat cells seem to remember unhealthy diet

Fri, 20 Apr 18 00:08:20 -0700

Fat cells can be damaged in a short amount of time when they are exposed to the fatty acid palmitate or the hormone TNF-alpha through a fatty diet, a new study shows. The researchers from Novo Nordisk Foundation Center for Basic Metabolic Research hope this new knowledge may be used to develop new preventive strategies for diabetes.

The bugs in your gut could make you weak in the knees

Thu, 19 Apr 18 00:00:40 -0700

Scientists have long thought that osteoarthritis in people who are obese was a consequence of excess wear and tear on joints, but a new study in JCI Insight suggests that the microbiome is the culprit. The study shows that a high fat diet (like the Western diet) can alter gut microbes, increase inflammation throughout the body, and speed deterioration of joints. An interesting twist: a common dietary supplement overturned these effects in mice.

Pregnant moms and their offspring should limit added sugars in their diets to protect childhood cognition

Thu, 19 Apr 18 00:08:50 -0700

A new study published in the American Journal of Preventive Medicine has determined that poorer childhood cognition occurred, particularly in memory and learning, when pregnant women or their offspring consumed greater quantities of sugar. Substituting diet soda for sugar-sweetened versions during pregnancy also appeared to have negative effects. However, children's fruit consumption had beneficial effects and was associated with higher cognitive scores.

UCalgary researchers develop a new method to discover drugs to treat epilepsy

Thu, 19 Apr 18 00:16:10 -0700

For more than a third of children living with epilepsy, the currently approved medications do not stop their seizures. Researchers at the Cumming School of Medicine have developed a new drug screening method to discover drugs to treat epilepsy.

Novel antioxidant makes old blood vessels seem young again

Thu, 19 Apr 18 00:00:10 -0700

Older adults who take an antioxidant that specifically targets mitochondria see age-related changes in blood vessels reverse by the equivalent of 15 to 20 years within six weeks, a new study shows.

People waste nearly a pound of food daily

Wed, 18 Apr 18 00:12:00 -0700

Americans waste nearly a pound of food per person each day, but the exact amount of food we trash differs by how healthy your diet is, a new PLOS ONE study finds. Between 2007-2014, consumers wasted nearly 150,000 tons of food per day. Researchers estimate that food waste corresponded with the use of 30 million acres of land (7 percent of total US cropland) and 4.2 trillion gallons of water annually. Higher quality diets were associated with higher levels of food waste.

Dietary lipids play diverse roles in disease

Thu, 12 Apr 18 00:13:00 -0700

This month's issue of the Journal of Lipid Research features studies examining how fats in the diet affect health, including whether the ketogenic diet is a reasonable cancer therapy; how the type of unsaturated fats in a mouse's chow affects inflammation; and how cells respond to nutrient signals.

The dinosaur menu, as revealed by calcium

Wed, 11 Apr 18 00:03:40 -0700

By studying calcium in fossil remains in deposits in Morocco and Niger, researchers have been able to reconstruct the food chains of the past, thus explaining how so many predators could coexist in the dinosaurs' time. This study was conducted by researchers from the CNRS, ENS de Lyon and Claude Bernard Lyon 1 University, in partnership with the French National Museum of Natural History and Sorbonne University.

Surprising discovery: Sweet tooth gene connected with less body fat

Wed, 11 Apr 18 00:02:40 -0700

Last year researchers from the University of Copenhagen discovered that a particular craving for sweet things may be determined by a genetic variation. Now the researchers, in collaboration with an English group, have discovered that people with this genetic disposition for a sweet tooth have less body fat.

Specific bacteria in the small intestine are crucial for fat absorption

Wed, 11 Apr 18 00:08:20 -0700

A new study -- one of a few to concentrate on microbes in the upper gastrointestinal tract -- shows how the typical calorie-dense western diet can induce expansion of microbes that promote the digestion and absorption of high-fat foods. Over time, the steady presence of these microbes can lead to over-nutrition and obesity.

Gene that makes humans eat more sugar can also lower body fat

Tue, 10 Apr 18 00:10:30 -0700

You are what you eat, the old saying goes. But what if, in fact, you eat certain things because of who you are? Scientists have known since 2013 that a common version of the gene FGF21 makes us consume more carbohydrates. Now, a group of researchers is showing that, despite the effect it has on diet, this gene variant actually decreases fat in the body. The results appear April 10 in the journal Cell Reports.

Vampire bats' bloody teamwork

Tue, 10 Apr 18 00:13:10 -0700

Vampire bats are the only mammals that feed exclusively on blood. The way they manage to do that offers us some remarkable insights into hologentics and evolution.

Fatty liver under stress

Mon, 09 Apr 18 00:14:50 -0700

A poor diet and other risk factors can result in liver disease. This important metabolic organ can become fatty and inflamed. In the long term, this may result in irreversible and life-threatening organ damage (cirrhosis of the liver or 'shrunken liver'). Experts at the German Federal Institute for Risk Assessment (BfR) in Berlin have now analyzed liver cells in vitro to investigate how degenerative fattening and inflammation can impair the body's primary detoxification system.

Binge-eating mice reveal obesity clues

Mon, 09 Apr 18 00:07:20 -0700

Mice fed on a high-fat or chocolate-based diet show abnormal feeding behaviors such as snacking, bingeing and disrupted eating patterns, according to new research from scientists at the Centre for Genomic Regulation (CRG) and the Pompeu Fabra University (UPF) in Barcelona, Spain. The findings of two studies published back-to-back in the journal Addiction Biology help to explain the behavioral triggers leading to obesity and point towards new ideas for preventing weight gain.

New study highlights benefits of weekly nutrition classes to improve type 2 diabetes

Fri, 06 Apr 18 00:08:00 -0700

Eating less enables lemurs to live longer

Thu, 05 Apr 18 00:01:30 -0700

Chronic caloric restriction strongly increases the lifespan of a small primate, the grey mouse lemur. This is one of the results of a ten-year experiment conducted by researchers at the CNRS and the MNHN. Chronic caloric restriction consists in eating a reduced but balanced diet from the outset of early adulthood. Its beneficial effect on lifespan had been established for many short-lived species (worms, flies, mice), but remained controversial for primates, including humans.

Diabetes awareness 'major concern' for UK Asians

Wed, 04 Apr 18 00:03:30 -0700

Links between eating red meat and distal colon cancer in women

Mon, 02 Apr 18 00:00:20 -0700

A new study suggests that a diet free from red meat significantly reduces the risk of a type of colon cancer in women living in the United Kingdom. When comparing the effects of certain diets to cancer development in specific subsites of the colon, scientists found that those regularly eating red meat compared to a red meat-free diet had higher rates of distal colon cancer -- cancer found on the descending section of the colon, where faeces is stored.

Eating more protein may not benefit older men

Mon, 02 Apr 18 00:07:30 -0700

A randomized, clinical trial conducted by Brigham and Women's Hospital investigator Shalender Bhasin, MD, and colleagues has found that higher protein intake did not increase lean body mass, muscle performance, physical function or other well-being measures among older men.

Can a Mediterranean diet pattern slow aging?

Fri, 30 Mar 18 00:14:00 -0700

A series of six articles appearing in the March issue of The Journals of Gerontology, Series A: Biological Sciences and Medical Sciences finds new correlations between a Mediterranean diet and healthy aging outcomes -- while also underscoring the need for careful approaches to the use of data in order to measure the diet's potential benefits.

Fungi found in the guts of healthy adults just travel through

Wed, 28 Mar 18 00:07:20 -0700

Fungi found in the gastrointestinal tracts of healthy adults are largely transient and stem from the mouth or foods recently consumed, according to new research published this week in mSphere, an open-access journal from the American Society for Microbiology.

Compared to nomadic communities, Silk Road cities were urban food deserts

Tue, 27 Mar 18 00:15:10 -0700

Like passionate foodies who know the best places to eat in every town, Silk Road nomads may have been the gastronomic elites of the Medieval Ages, enjoying diets much more diverse than their sedentary urban counterparts, suggests a new study in the Nature journal Scientific Reports.

The connection between diet, obesity, and cancer: Nutrition experts explore the evidence

Tue, 27 Mar 18 00:12:30 -0700

About one third of cancer cases are estimated to be linked to dietary and other modifiable risk factors, especially for obesity-related cancers such as breast, colorectal, ovarian, endometrial, kidney, gallbladder, esophageal, and pancreatic cancers. In this special theme issue of the Journal of the Academy of Nutrition and Dietetics, food and nutrition practitioners and other health professionals take an in-depth look at the relationship between nutrition, obesity, and cancer prevention, treatment, and survival and identify research gaps for future prevention research efforts.

Sulfur amino acid restriction diet triggers new blood vessel formation in mice

Thu, 22 Mar 18 00:04:00 -0700

Putting mice on a diet containing low amounts of the essential amino acid methionine triggered the formation of new blood vessels in skeletal muscle, according to a new study from Harvard T.H. Chan School of Public Health. The finding adds insight to previous research showing that a methionine-restricted diet extends lifespan and healthspan, suggesting that improved vascular function may contribute to these benefits.

Eating pecans had significant effect on biomarkers of heart disease and type 2 diabetes

Thu, 22 Mar 18 00:08:10 -0700

A new study published in Nutrients shows that eating just 1.5 ounces of pecans -- one small handful -- every day may protect adults at risk for developing cardiovascular disease (CVD) and type 2 diabetes (T2D).

FASEB Journal: Study shows offspring response to maternal diet and male hormone

Thu, 22 Mar 18 00:10:50 -0700

How obesity dulls the sense of taste

Tue, 20 Mar 18 00:02:20 -0700

Previous studies have indicated that weight gain can reduce one's sensitivity to the taste of food. Now a study publishing March 20 in the open-access journal PLOS Biology by Andrew Kaufman, Robin Dando, and colleagues at Cornell University shows that inflammation, driven by obesity, actually reduces the number of taste buds on the tongues of mice.

Western diet depletes artery-protecting immune cells

Tue, 20 Mar 18 00:10:00 -0700

New research from scientists at the La Jolla Institute shows how a diet high in fat and cholesterol depletes the ranks of artery-protecting immune cells, turning them into promoters of inflammation, which exacerbate atherosclerotic plaque buildup that occurs in cardiovascular disease. The team has also found that high density lipoproteins (HDL)--more commonly known as

High omega-6 levels can protect against premature death

Mon, 19 Mar 18 00:00:40 -0700

Could omega-6 fatty acids protect you against premature death? The answer is yes, according to a new University of Eastern Finland study. While protecting against death, omega-6 fatty acids also keep cardiovascular diseases at bay.
