The food additive carrageenan (E 407) can be responsible for the development of chronic inflammatory bowel disease, ulcers, and increased blood sugar levels in animals. Researchers have now investigated the effects of carrageenan on the human intestine and sugar metabolism. They found increased permeability of the small intestine, most likely due to intestinal inflammation.
Tirzepatide, a new injectable weight-loss drug, reduced the risk of diabetes in patients with obesity and prediabetes by more than 90% over a three-year period, compared with placebo, according to the results of a new study.
Polybrominated diphenyl ethers, or PBDEs, are fire-retardant chemicals that are found everywhere. A mouse study reports that probiotic supplementation can reduce the negative impacts of PBDEs on neurodevelopment, behavior, and metabolism.
A multicenter examination of data demonstrates that for patients with a body mass index at or above 70 kg/m2 metabolic and bariatric surgery is a potent intervention.
Weight-loss and diabetes drug tirzepatide can reduce the risk of death or worsening heart failure for patients with obesity and heart failure with preserved pump function, new research reveals.
Incidence of stroke and ischemic heart disease are declining around the world, except for in a handful of regions, according to a new study. Researchers find that in East and West Sub-Saharan Africa, East and Central Asia and Oceania, ischemic heart disease is increasing, which may be attributed to eight factors that include diet, high BMI, household air pollution and more.
Fiber is something that most of us get far too little of. To change that, we need to actually enjoy eating it. Food researchers have now invented a 'disguise' that solves the problem of the dry and gritty mouth feel of fibers.
As rates of obesity, as defined by body mass index (BMI), continue to climb in the United States, so have efforts to lose weight, including a new era of weight-loss drugs. Yet a new systematic review and meta-analysis found that cardiorespiratory fitness was a stronger predictor of both cardiovascular disease and all-cause mortality than BMI.
Salk scientists have tracked the flow of trans fats using mouse models to describe the molecular mechanisms that cause trans fats to promote atherosclerotic cardiovascular disease (ASCVD), explaining how industrially produced trans-unsaturated fatty acids in our food significantly promote ASCVD and encouraging lawmakers to impose regulations on the use of these fats in food. This new insight into the flow of fats through the body points to new therapeutic targets for mitigating diseases like ASCVD, non-alcoholic fatty liver disease, obesity, diabetes, peripheral neuropathy, and neurodegeneration.
Shifting our diets to be more sustainable can be a powerful way for each of us to address both climate change and global food insecurity, however making such adjustments at the large scales necessary to make a difference globally can be a delicate matter.
Researchers have found a potential method to slow heart failure progression. They fed mice a diet high in soybean protein, which influenced gut bacteria and supported heart health. Analysis showed that this diet increased the production of the short-chain fatty acids in the gut that help to protect the heart.
Researchers have identified a new target to treat atherosclerosis, a condition where plaque clogs arteries and causes major cardiac issues, including stroke and heart attack.
Obesity causes insulin resistance by increasing activation of the sympathetic nervous system and the release of the stress hormone norepinephrine, according to a new study.
Since 1990, childhood obesity has nearly doubled globally, with the U.S. at the forefront. Addressing pediatric obesity requires a multifaceted approach from tackling the influence of social media and advertising on children's food choices to increasing physical activity.
With Medicare now covering semaglutide for people with obesity and cardiovascular disease who don't have diabetes, a study looks at who that might include, depending on what cutoffs prescription plans apply.
People who work the nightshift or odd hours and eat at irregular times are more prone to weight gain and diabetes, likely due to eating patterns not timed with natural daylight and when people typically eat. But is it possible to stave off the ill effects of eating at these 'unusual' times despite it not being biologically preferable? A study says 'yes', and sheds light on how the body knows when to eat. The study explains how researchers discovered a connection between the liver's internal clock and feeding centers in the brain.
Slightly overweight stroke survivors have a lower risk of sustaining disabilities. New research adds another aspect to the obesity paradox but also highlights the importance of considering the population's normal when recommending best practices.
Being a scientist has its challenges. Knowing how to communicate your scientific research in a socially responsible manner can be even more difficult. Thankfully, researchers have identified some of the trade-offs and communication strategies that environmental health scientists can use to communicate more effectively.
More children have overweight in regions with high rates of single parenthood, low education levels, low income and high child poverty. The pandemic may also have reinforced this trend.
Scientists have long suspected the keto diet might be able to calm an overactive immune system and help some people with diseases like multiple sclerosis. Now, they have reason to believe it could be true. Scientists have discovered that the diet makes the gut and its microbes produce two factors that attenuated symptoms of MS in mice.
