Published Study of ancient British oral microbiomes reveals shift following Black Death
(via sciencedaily.com) Original source The Second Plague Pandemic of the mid-14th century, also known as the Black Death, killed 30-60 percent of the European population and profoundly changed the course of European history. New research suggests that this plague, potentially through resulting changes in diet and hygiene, may also be associated with a shift in the composition of the human oral microbiome toward one that contributes to chronic diseases in modern-day humans.
Published Are healthy foods automatically sustainable, too?
(via sciencedaily.com) Original source Perceptions about sustainability and healthy food choices are closely linked, a new study shows.
Published Alcohol consumption may have positive and negative effects on cardiovascular disease risk
(via sciencedaily.com) Original source A new study found that alcohol consumption may have counteractive effects on CVD risk, depending on the biological presence of certain circulating metabolites -- molecules that are produced during or after a substance is metabolized and studied as biomarkers of many diseases. The researchers observed a total of 60 alcohol consumption-related metabolites, identifying seven circulating metabolites that link long-term moderate alcohol consumption with an increased risk of CVD, and three circulating metabolites that link this same drinking pattern with a lower risk of CVD.
Published Fat cells help repair damaged nerves
(via sciencedaily.com) Original source Damage to the body's peripheral nerves can cause pain and movement disorders. Researchers have recently investigated how damaged nerves can regenerate better. They found that fat tissue strongly supports the Schwann cells needed for repair during the healing process.
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 Study reveals surprising link between malnutrition and rising antibiotic resistance
(via sciencedaily.com) Original source Researchers have uncovered startling connections between micronutrient deficiencies and the composition of gut microbiomes in early life that could help explain why resistance to antibiotics has been rising across the globe. The team investigated how deficiencies in crucial micronutrients such as vitamin A, B12, folate, iron, and zinc affected the community of bacteria, viruses, fungi and other microbes that live in the digestive system. They discovered that these deficiencies led to significant shifts in the gut microbiome of mice -- most notably an alarming expansion of bacteria and fungi known to be opportunistic pathogens. Importantly, mice with micronutrient deficiencies also exhibited a higher enrichment of genes that have been linked to antibiotic resistance.
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 Vitamin B12: A key player in cellular reprogramming and tissue regeneration
(via sciencedaily.com) Original source Researchers reveal that vitamin B12 significantly boosts the efficiency of cellular reprogramming, thus holding promise for regenerative medicine. Vitamin B12 supplementation shows potential in speeding up tissue repair in a model of ulcerative colitis -- an observation that points to potential new treatments for inflammatory diseases.
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.
