Published Mice eating less of specific amino acid -- overrepresented in diet of obese people -- live longer, healthier
(via sciencedaily.com) Original source A new study in mice shows that cutting down the amount of a single amino acid called isoleucine can, among other benefits, extend their lifespan, make them leaner and less frail as they age and reduce cancer and prostate problems, all while the mice ate more calories.
Published Nutrient found in beef and dairy improves immune response to cancer
(via sciencedaily.com) Original source Trans-vaccenic acid (TVA), a long-chain fatty acid found in meat and dairy products from grazing animals such as cows and sheep, improves the ability of CD8+ T cells to infiltrate tumors and kill cancer cells, according to a new study.
Published From the first bite, our sense of taste helps pace our eating
(via sciencedaily.com) Original source When you eagerly dig into a long-awaited dinner, signals from your stomach to your brain keep you from eating so much you'll regret it -- or so it's been thought.
Published Ultra-processed foods and higher risk of mouth, throat and esophagus cancers
(via sciencedaily.com) Original source Eating more ultra-processed foods (UPFs) may be associated with a higher risk of developing cancers of upper aerodigestive tract (including the mouth, throat and esophagus), according to a new study. The authors of this international study, which analyzed diet and lifestyle data on 450,111 adults who were followed for approximately 14 years, say obesity associated with the consumption of UPFs may not be the only factor to blame.
Published Why do some people get headaches from drinking red wine?
(via sciencedaily.com) Original source Researchers think that a flavanol found naturally in red wines can interfere with the proper metabolism of alcohol and can lead to a headache.
Published Feeding dogs raw meat increases the risk of antibiotic-resistant E. coli
(via sciencedaily.com) Original source Feeding dogs raw (uncooked) meat increases their risk of excreting E. coli that cannot be killed by a widely used antibiotic -- ciprofloxacin -- researchers have found from a study of 600 healthy pet dogs.
Published Following a Mediterranean diet reduces the risk of cognitive decline in older people
(via sciencedaily.com) Original source Old people who follow a Mediterranean diet are at a lower risk of cognitive decline, according to a new study. The study provides new evidence for a better understanding of the biological mechanisms related to the impact of the diet on cognitive health in the aging population.
Published Hunger hormones impact decision-making brain area to drive behavior
(via sciencedaily.com) Original source A hunger hormone produced in the gut can directly impact a decision-making part of the brain in order to drive an animal's behavior, finds a new study.
Published People with obesity burn less energy during day
(via sciencedaily.com) Original source A study found people who have a healthy weight use more energy during the day, when most people are active and eat, while those who have obesity spend more energy during the night, when most people sleep. Researchers also found that, during the day, those with obesity have higher levels of the hormone insulin -- a sign that the body is working harder to use glucose, an energy-packed sugar.
Published Peer educators play key role in new recipe development and testing
(via sciencedaily.com) Original source Cooking and recipe demonstrations encourage healthy eating and adoption of unfamiliar foods by class participants.
Published Cycle of fasting and feeding is crucial for healthy aging
(via sciencedaily.com) Original source Fasting interventions, which involve alternating periods of fasting and refeeding, are generally thought to improve health. But these interventions don't work as well in old animals. The question is: Why? By studying the short-lived killifish, researchers have shown that older fish deviate from a youthful fasting and refeeding cycle, and instead enter a state of perpetual fasting, even when ingesting food. However, the benefits of refeeding after fasting in old killifish can be restored by genetically activating a specific subunit of AMP kinase, an important sensor of cellular energy. These mutant fish experienced improved health and longevity, indicating that both fasting and refeeding are needed to confer health benefits and act through AMP kinase to do so.
Published Cut salt, cut blood pressure
(via sciencedaily.com) Original source Nearly everyone can lower their blood pressure, even people currently on blood pressure-reducing drugs, by lowering their sodium intake, reports a new study. It found 70-75% of all people, regardless of whether they are already on blood pressure medications or not, are likely to see a reduction in their blood pressure if they lower the sodium in their diet. Losing one teaspoon of salt a day results in systolic blood pressure decline comparable to effect achieved with drugs.
Published Ground-breaking discovery could pave the way for new therapies to prevent cardiovascular disease and stroke
(via sciencedaily.com) Original source Researchers have discovered the mechanism by which cholesterol in our diet is absorbed into our cells. This discovery opens up new opportunities for therapeutic intervention to control cholesterol uptake that could complement other therapies and potentially save lives.
Published Study finds melatonin use soaring among youth
(via sciencedaily.com) Original source Nearly one in five school-aged children and preteens now take melatonin for sleep, and some parents routinely give the hormone to preschoolers, according to new research.
Published Allergic responses to common foods could significantly increase risk of heart disease, cardiovascular death
(via sciencedaily.com) Original source Allergic responses to common foods such as dairy and peanuts can increase the risk for heart disease and cardiovascular death as much or more than smoking, new research suggests. And these dangerous allergic responses can strike both people with food allergies and those with no obvious allergy symptoms.
Published Early life exposure to broccoli sprouts protects against colitis in inflammatory bowel disease
(via sciencedaily.com) Original source High fiber diets, like those that include broccoli sprouts or other cruciferous vegetables, may reduce disease symptoms and improve quality of life in patients with inflammatory bowel disease (IBD).
Published Clinical trial data suggests prenatal vitamin D reduces a child's risk of asthma
(via sciencedaily.com) Original source A review of 15 years' worth of data found that vitamin D supplementation during pregnancy was linked to reduced rates of asthma and wheezing in children compared to standard prenatal multivitamin.
Published Blood clotting risk quickly drops after stopping hormonal contraceptives
(via sciencedaily.com) Original source Using birth control pills and other hormone-based contraceptives is known to elevate the risk of blood clots, but a new study suggests that this risk largely goes away within two to four weeks after one stops using these contraceptives. The findings can help patients and doctors weigh the benefits and risks of hormonal contraceptives and guide when to stop using them ahead of events that could further increase the risk of dangerous clots, such as major surgery, prolonged periods of immobility, or when tapering anticoagulant medications after a blood clot.
Published Obesity linked to neurodegeneration through insulin resistance
(via sciencedaily.com) Original source Researchers have discovered a link between obesity and neurodegenerative disorders like Alzheimer's disease. Using the common fruit fly, the research shows that a high-sugar diet -- a hallmark of obesity -- causes insulin resistance in the brain, which in turn reduces the ability to remove neuronal debris, thus increasing the risk of neurodegeneration.
Published Visualizing fungal infections deep in living host tissue reveals proline metabolism facilitates virulence
(via sciencedaily.com) Original source Scientists have published the first successful application of 2-photon intravital microscopy (IVM) to image the dynamics of fungal infections in the kidney of a living host. The study reveals that the opportunistic human fungal pathogen Candida albicans requires the ability to metabolize proline, an amino acid obtained from the host, to mount virulent infections.
