Swapping that steak for a fish filet or a veggie burger is not only good for your health, but the planet’s, too, a new study suggests. The study, published in the American Journal of Clinical Nutrition, ranked various diets based on two measures: nutritional quality and “carbon footprint.” And overall, non-meat diets came out on top, on both counts. Researchers found that on average, vegan and vegetarian diets had the smallest carbon footprint — which refers to the amount of greenhouse gases that are churned into the atmosphere in order to produce the foods the diets comprise. Meanwhile, the pescatarian diet — which includes seafood, but no meat — scored highest in nutritional quality, and was more planet-friendly than diets containing meat. On the opposite end of the spectrum were two diets currently in vogue: the high-fat, low-carbohydrate keto diet; and the paleo diet, which centers on foods its proponents say were consumed in prehistoric times — mainly meat, fish, eggs, nuts and vegetables. Those two meat-heavy eating plans, the study found, carried the biggest carbon footprints and lowest dietary quality. (The keto diet may also be tough on the heart, raising levels of “bad” cholesterol and the risk of artery blockages, according to new research presented at a meeting of the American College of Cardiology). Experts said the findings may give consumers some food… read on > read on >
All Eats:
Could the Mediterranean Diet Help People With MS?
A Mediterranean diet may help multiple sclerosis (MS) patients ward off damage to their thinking skills. New research finds that a diet rich in veggies, fruit, fish and healthy fat reduced their risk of developing memory loss as well as losing the ability to concentrate, learn new things or make decisions. A loss of such key mental skills, or “cognitive impairment,” is a common feature of MS, a neurological disease that short circuits critical communication between the brain and body. But the new analysis of diet and mental status among 563 people with MS linked the Mediterranean diet to a 20% lower risk for cognitive difficulties. “Mediterranean diet is a broad term and there are geographical variations,” said lead author Dr. Ilana Katz Sand, an associate professor of neurology at Icahn School of Medicine at Mount Sinai in New York City. “However, it refers to an overall pattern that favors fruits, vegetables, olive oil, nuts, fish, and whole grains and limits meats — particularly red meat — baked goods, and highly processed foods.” Prior research has suggested that Mediterranean diets “have broad health benefits,” Katz Sand added, including some protection against heart disease, obesity, cancer, diabetes, Alzheimer’s and overall mental health decline. “In this study,” she said, “we demonstrate a significant positive association between the level of alignment of one’s diet with a Mediterranean pattern… read on > read on >
FDA Panel Backs Second RSV Vaccine for Older Americans
Following hours of discussion over safety concerns, a U.S. Food and Drug Administration advisory panel on Wednesday recommended approval of a second RSV vaccine, this one made by GlaxoSmithKline, for use in Americans ages 60 and older. The panel’s recommendation was based largely on the results of a trial that tested the GlaxoSmithKline vaccine in the same age group. Those findings, published recently in the New England Journal of Medicine, showed that the shot lowered the risk of symptomatic illness by 83% and of severe illness by 94% in people ages 60 and up. In a two-part vote, the panel voted 10 to 2 in favor of the vaccine’s safety and unanimously on the shot’s effectiveness, the New York Times reported. Meanwhile, the same panel on Tuesday recommended the approval of an RSV vaccine known as RENOIR from Pfizer Inc. On both days, panel members debated the benefits of the vaccines for patients who overwhelmingly avoided hospitalization against rare reports of autoimmune conditions like Guillain-Barré syndrome that emerged shortly after the shots were administered. In addition, two people who were given the GSK vaccine developed acute disseminated encephalomyelitis, a neurological disorder with symptoms that include weakness and loss of vision. One person died. The company and the FDA consider the cases “possibly related” to the vaccine, noting that both patients also received a flu vaccine… read on > read on >
Smoking Plus Mental Illness Can Send Caffeine Intake Soaring
One group of Americans drinks more caffeinated beverages than all others. That’s people who smoke cigarettes and also have serious mental illness, including schizophrenia and bipolar disorder, according to new research. While Americans overall are drinking more caffeinated beverages than ever, this group consumes the highest amount and also has the highest risk of negative health consequences, said researcher Dr. Jill Williams, director of addiction psychiatry at Rutgers Robert Wood Johnson Medical School in New Jersey, and colleagues. “Caffeine is generally considered safe and even has some health benefits,” Williams said in a Rutgers news release. “But we just don’t understand the cognitive and psychiatric effects of high caffeine intake, especially among smokers with mental illness.” The researchers analyzed data from 248 adult smokers who were recruited during a previous study. Participants were either outpatients with schizophrenia or bipolar disorder or from a control group with no psychiatric diagnoses. Each smoked a pack a day. Researchers collected blood samples from the participants to measure their serum caffeine levels. Participants also completed surveys on smoking history, caffeine use, physical health and psychological symptoms. While caffeine intake was highest in those with bipolar disorder, followed by schizophrenia, it was lowest in the control group. Williams suggested several theories that might help explain why this connection exists. First, there’s a well-established association between caffeine and smoking. People who… read on > read on >
Bed Rails Can Help and Harm: FDA Gives Guidance
While adult bed rails are marketed with safety in mind, they need to be used with caution, the U.S. Food and Drug Administration advises. “Many death and injury reports related to entrapment and falls for adult portable bed rail products and hospital bed rails have been reported to the FDA and the CPSC [U.S. Consumer Product Safety Commission],” the FDA said in a new webpage. Use bed rails with care, especially with older adults and people with altered mental status, physical limitations and certain medical conditions, the FDA advised. The FDA regulates bedrails that are sold for medical purposes. These might be used to help someone who is disabled, injured or recovering from surgery to transfer in and out of bed, and reduce the risk of falling or fracture. Those not marketed for medical purposes are instead considered consumer products and are under the jurisdiction of the CPSC. Sometimes these types of equipment are called side rails, bed side rails, half rails, safety rails, bed handles, bed canes, assist bars, grab bars, and adult portable bed rails. The FDA’s new webpage explains some of the risks associated with bed rails and offers some safety advice. Bed rails typically are divided into three distinct types, according to the FDA. There are portable bed rails for adults, portable bed rails used for children, and hospital bed rails… read on > read on >
FDA Panel Backs Pfizer’s RSV Vaccine for Older Americans
In a tight vote, U.S. Food and Drug Administration advisors on Tuesday recommended the approval of an RSV vaccine that could be used in Americans ages 60 and up. The vaccine, known as RENOIR, was developed by pharmaceutical giant Pfizer Inc. The same panel of advisors will weigh the potential approval of another respiratory syncytial virus (RSV) vaccine, this one from GlaxoSmithKline, on Wednesday. “In older adults, RSV can result in serious illness, hospitalization, or even death, so there is a significant need to protect this at-risk population,” Annaliesa Anderson, senior vice president and chief scientific officer for vaccine research and development at Pfizer, said in a news release announcing the panel decision. “We are encouraged by the outcome of today’s… meeting, as it is a testament to the strength of our science and dedication to bringing this important vaccine candidate to the market.” If the FDA follows the recommendation of its advisors, which it typically does, Pfizer’s vaccine would be the first shot to guard against RSV infection, NBC News reported. The U.S. Centers for Disease Control and Prevention would also need to recommend the single shot before it could become available to Americans. Still, the FDA advisors were divided in their recommendation. The panel voted 7-4, with one abstention, to recommend approval of the vaccine based on its efficacy, NBC News reported. FDA… read on > read on >
Could Tiny Plastic Particles Reach the Fetus From Mom’s Food? Rat Study Raises Concerns
Most food and water contains “nano-sized” microplastics, and new animal research suggests these tiny particles pass from pregnant rats to their unborn offspring and may impair fetal development. The same could be true in humans, the study suggests. “Much remains unknown, but this is certainly cause for concern and follow-up study,” said Philip Demokritou, a professor of nanoscience and environmental bioengineering at the Rutgers School of Public Health, in New Jersey. A typical person ingests about a credit card’s worth of microscopic plastic particles each week, Demokritou estimated. This plastic is consumed through food and the air after erosion breaks down items exposed to the environment. Previous studies in pregnant laboratory animals have found adding these plastics to food impairs their offspring, but those studies didn’t determine whether the plastics could pass from mother to baby. For this study, researchers fed these nanoscale plastics to five pregnant rats. Through imaging, they found that those plastic particles permeated the placentas, as well as the livers, kidneys, hearts, lungs and brains, of their offspring. This shows that these plastics can breach the intestinal barrier of pregnant mammals, the maternal-fetal barrier of the placenta and all fetal tissues, the study authors said. “The use of plastics has exploded since the 1940s due to their low cost and versatile properties. From 9 billion metric tons produced over the last… read on > read on >
FDA Takes Action Against Animal Tranquilizer Tied to Fatal ODs
The U.S. Food and Drug Administration said Tuesday that it has taken action to restrict imports of the veterinary tranquilizer xylazine to prevent illicit use of the drug. While veterinarians use products containing xylazine to sedate large animals such as horses and deer, the drug is not safe for people. It is sold on the street under the names tranq, Philly dope and zombie drug. Federal officials say illicit drugs, including fentanyl and meth and cocaine, are often laced with xylazine. The drug has been detected in a growing number of overdose deaths. People who use illicit drugs may not be aware they contain xylazine, the FDA warned. “The FDA remains concerned about the increasing prevalence of xylazine mixed with illicit drugs, and this action is one part of broader efforts the agency is undertaking to address this issue,” FDA Commissioner Dr. Robert Califf said in an agency news release. “We will continue to use all tools at our disposal and partner with the Drug Enforcement Administration and other federal, state, local agencies and stakeholders as appropriate to stem these illicit activities and protect public health.” The FDA wants to ensure that imports of drugs containing xylazine are intended for legitimate veterinary use. That includes ingredients for processing at a facility that makes FDA-approved xylazine, compounding at licensed pharmacies and veterinary practices, as well as… read on > read on >
Could a Common Sweetener Raise Heart Risks?
An artificial sweetener commonly used in processed foods could be increasing people’s risk of heart attack and stroke, a new study argues. Erythritol is a natural sugar alcohol found in many vegetables and fruit. Even the human body produces small amounts of erythritol. But higher levels of the sweetener added to processed foods might increase people’s risk of blood clots, researchers reported Feb. 27 in the journal Nature Medicine. People who had large amounts of erythritol in their blood were up to twice as likely to suffer a heart attack or stroke compared to those with the least amounts, the researchers found. “I think there’s plenty of data here to argue that we should be reading our labels and avoiding erythritol, particularly if you’re at risk for cardiovascular disease,” said senior researcher Dr. Stanley Hazen, chair of cardiovascular and metabolic sciences at the Cleveland Clinic’s Lerner Research Institute. But other experts expressed skepticism, saying more study is required before erythritol can be considered potentially harmful. “At this point, I think that using small amounts of this, whether it should be in some power bar that you eat or you use a granulated form to put it in your coffee or tea or to have occasionally on your oatmeal, I just don’t think it’s a worrisome thing at this point in time,” said Dr. Karen Aspry,… read on > read on >
Milk, or a Plant-Based ‘Milk’: What’s the Nutritional Difference?
Not all milks are created equally when it comes to nutrients. Reading the label can clue you in to what you’re getting out of the beverage, whether it be plant-based or dairy, according to the U.S. Food and Drug Administration. Nutritional content can vary between different plant-based products, the FDA said in a recent news release. Many don’t have the same amount of calcium, vitamin D or other nutrients as dairy milk. The only plant-based beverage that contains a similar enough nutrient content that it can be included in the dairy group in the federal government’s Dietary Guidelines for Americans is fortified soy milk. “The nutrients you get from plant-based milk alternatives can depend on which plant source is used, the processing methods and added ingredients, so check the label carefully,” said Susan Mayne, director of the Center for Food Safety and Applied Nutrition at the FDA. “Has the product been fortified with nutrients such as calcium? How much added sugar is in the product? What is the protein content?” “The Nutrition Facts label on the packaging can help you compare the nutrient content of the various plant-based milk alternatives to milk,” Mayne said. “The label can help you choose the best products to meet your nutrient needs and those of your family.” Plant-based milks can be made from grains, such as oat, quinoa and… read on > read on >
