What Parents Should Know About the FDA's Latest Food Additive Approval
Fact checked by Sarah ScottThe FDA is attempting to phase out petroleum-based dyes from the nation's food supply. It approved one more natural food additive, gardenia (genipin) blue, in addition to three previous one: Galdieria extract blue, calcium phosphate, and butterfly pea flower extract. These approved food additives are generally considered safe, and some are already being U.S. Food and Drug Administration (FDA) just approved a new food additive: gardenia (genipin) blue. It can be used in sports drinks, flavored or enhanced non-carbonated water, fruit drinks and ades, ready-to-drink teas, as well as hard and soft candy. The move comes about two months after the FDA approved Galdieria extract blue, calcium phosphate, and butterfly pea flower extract, in an attempt to phase out petroleum-based dyes from the nation's food supply. 'The FDA's approval likely reflects a response to consumer demand for more natural food coloring options,' says Daniel S. Ganjian, MD, a board-certified pediatrician at Providence Saint John's Health Center in California. 'These additives are derived from natural sources—algae and a flower—which differentiates them from many synthetic food dyes that are chemically manufactured.' But what do we know about the roots and safety of the new FDA-approved food additives? Experts share their thoughts on the FDA's decisions and offer guidance on how parents can select safe, nourishing foods for their children. The word 'additives' gets thrown around a lot when discussing food (and body care products, for that matter). It might be helpful to have a primer or reminder on what experts refer to as additives. 'Food additives are substances added to food to perform specific functions, such as enhancing flavor, color, texture, or preserving freshness,' Dr. Ganjian says. 'They help maintain consistency, improve appearance, and extend shelf life.' However, recent data has pointed to a potential link between synthetic food dyes and behavioral issues and developmental delays in children. "While not all experts agree on the level of harm, one thing is clear: These petroleum-based dyes don't offer any health benefit," says Don Thushara Galbadage, PhD, MPH, an associate professor at Texas Christian University and an expert on food additives and dyes. And that's a key objective of the FDA's approval of these new additives. 'This approval will hopefully make it easier for food companies to use them in their products," says Sotiria Everett, EdD, RD, CDN, CSSD, a clinical assistant professor at Stony Brook Medicine. The FDA-approved gardenia (genipin) blue, Galdieria extract blue, calcium phosphate, and butterfly pea flower extract are not petroleum-based. Some already serve purposes in commonly used items. Here's the breakdown. This is a natural blue food color additive derived from the gardenia fruit. This is already widely used in Asia for food products, such as frozen desserts, jams, baked good, and beverages. Research has found it is not carcinogenic, even in high doses. Galdieria extract blue comes from Galdieria sulphuraria, a species of red algae, explains Dr. Everett. The FDA approved its use in numerous foods, including fruit smoothies, juices, milkshakes, candy, yogurt drinks, and other processed foods. Dr. Everett shares that studies in rats didn't show adverse effects in daily doses of 4,000 milligrams per kilogram of bodyweight and says the estimated exposure to Galdieria extract blue will be far less (325 to 525 milligrams per kilogram daily). The FDA and outside experts currently recognize Galdieria extract blue as generally safe. Butterfly pea flower extract is an additive used to color foods various shades of blue, purple, and green, explains Anthony Hudson, MD, FAAP, ABOM, a pediatrician with Manning Family Children's in New Orleans. 'It is produced through the water extraction of the dried flower petals of the butterfly pea plant,' Dr. Hudson says. Dr. Everett notes that you and your children may have already had foods and drinks with this food additive. It is already in certain foods and beverages, like: Sports drinks Fruit drinks Dairy drinks Candy Yogurt Ice cream 'The FDA approval will expand its use to ready-to-eat cereals, crackers, snack mixes, hard pretzels, plain potato chips, corn chips, tortilla chips, and multigrain chips,' Dr. Everett says. She notes that the Taiwanese government issued a warning in 2019 about using butterfly pea extract in large quantities, with side effects potentially including nausea and diarrhea. However, the Taiwanese government said it could be used in the minimum amount to achieve the desired color. Dr. Galbadage also says butterfly pea flower extract is generally considered safe as a food additive in small quantities. Calcium phosphate is a white, naturally occurring mineral compound that Dr. Ganjian says is also used as a food additive. 'It serves multiple purposes, including as an anticaking agent, a source of calcium, and to modify texture,' Dr. Ganjian says. You also may use it to clean food off your teeth—calcium phosphate is commonly used in toothpastes, explains Lacy Puttuck, MS, RDN, a registered dietitian with Top Nutrition Coaching. 'It's not new, as this additive has been in baby formulas and cereals for years and is usually recognized as safe,' Dr. Galbadage adds. 'Now, it's approved for things like doughnut sugar, white candy melts, and some ready-to-eat meats.' While some changes take significant time, experts believe parents will begin to see these items on more food labels soon. But the full effects are likely at least a year away. 'The FDA has set a timeline for phasing out synthetic dyes, and companies are already responding,' Dr. Galbadage says. 'Some major brands have committed to removing artificial dyes by the end of next year. That means by 2026, your child's cereal, snacks, and even yogurts may still be colorful, but with more natural ingredients behind their color.' How can parents navigate the grocery store in the meantime, and even after the new additives become more prevalent? Trust your eyes when deciding what to put in your mouth and gut. 'Read the ingredients list of food products,' suggests Puttuck. 'Make sure you can read and understand all of the ingredients in a food. This will allow you to make more informed choices for your family.' 'Natural' doesn't always mean 'healthiest' or 'without any risk." Candy and chips with butterfly pea flower still may have more than the daily recommended values of sugar and salt, for instance. Dr. Hudson suggests consuming a diet of single-ingredient foods, like an apple, broccoli, and unprocessed proteins, including legumes, and omega-3-packed fish, such as salmon, without tons of salt. 'Children will follow their caregivers' example,' Dr. Hudson says. 'If the caregivers prepare single-ingredient foods at home and include the children in the growing or purchasing of food and the preparation of the food, they too will eat healthy options.' Repeat after us: You cannot control what your child eats at a birthday party or eats out of a goody bag on the carpool ride home. 'It is hard to completely eliminate these foods, especially in many social occasions, such as birthday parties, movie outings, and other events that families enjoy,' Dr. Everett says. She suggests focusing on practical steps and balance. Swapping foods with 'unnaturally bright colors' like chips for crunchy veggies and hummus at meals and for snacks, is one way to bump items with synthetic dyes into the 'sometimes' territory. Also, whole fruits like watermelon have natural but not added sugars, as many juices do. 'Stay informed but maintain perspective,' Dr. Ganjian agrees. 'Keep up with information from reputable sources like the FDA, but remember that the agency has processes in place to ensure the safety of approved additives. Avoid unnecessary anxiety and focus on a balanced and varied diet.' Read the original article on Parents

Vitamin D supplements may help slow down aging by 3 years
Vitmain D supplements may impact etelemore length and helo slow down aging, according to new research. Bowery Image Group Inc./Stocksy Telomeres, the protective caps at the ends of chromosomes, are an important component of healthy aging. One study found that vitamin D supplementation helps to minimize the shortening of telomeres, which happens as people get older, and thus may protect against diseases tied to age and biological aging. This data adds to the potential protective components of vitamin D, which experts should consider alongside potential risks and additional research. As the authors of this study explained, telomeres help protect the ends of chromosomes. Telomere shortening might increase the risk of death and certain diseases. David Cutler, MD, a board certified family medicine physician at Providence Saint John's Health Center in Santa Monica, CA, who was not involved in the study, told Medical News Today that 'When telomeres become too short, cells enter senescence (a non-dividing state) or apoptosis (programmed cell death). Either condition of cell inactivity or death is thought to contribute to aging and age-related diseases.' The researchers found that vitamin D supplementation helped minimize telomere shortening in white blood cells, which could help slow down biological aging. For this study, researchers used data from the VITAL trial. This trial included a representative sample of adults in the United States who received vitamin D3 supplements, omega-3 fatty acid supplements, or both for around five years. It was a double-blind, placebo-controlled study, so some participants received the supplements while others received the placebo. All female participants were at least fifty-five years old, and all male participants were at least fifty. This data specifically examined a cohort that visited the Harvard Clinical and Translational Science Centre. At baseline and follow-up visits, participants participated in in-person assessments and provided fasting blood samples. Researchers examined telomere length in leukocytes , which are the body's white blood cells, among participants who received supplements and those who received the placebo. Researchers were able to analyze over 2,500 samples from over 1,000 participants. They examined telomere length at baseline and at two- and four-year follow-up, though some data was missing. They conducted a statistical analysis using models to adjust for various covariates. They also did an exploratory subgroup analysis to see how different factors, such as high blood pressure and diabetes, impacted results. Aside from a higher body mass index in the omega-3 fatty acid supplement group, the placebo and intervention groups had similar baseline characteristics. Missing data was also similar between the two groups. Vitamin D appeared to have a positive impact on telomere length. Among participants who received vitamin D, there was only minimal shortening of telomere length at two and four years. In contrast, there was substantial telomere shortening in the placebo group at both time points. Omega-3 fatty acids supplementation appeared to have no significant impact on telomere length. The subgroup analysis further suggested that the effects of vitamin D on telomere length were significant for participants not taking medication for cholesterol, but not for participants who were taking cholesterol medication. Vitamin D also minimized telomere shortening at a statistically significant level for non-white participants. There was no significant interaction with body mass index, but researchers did observe that participants who were not obese had significantly minimized telomere shortening. Also, taking omega-3 fatty acid supplements did not appear to impact the role of vitamin D on telomere length. This analysis of telomere length in this study population does have some limitations. First, most participants were white, and all participants were at least fifty, so it may not be possible to generalize the findings to other groups. Researchers acknowledge that this was a post-hoc analysis of an already completed study and that the study was not originally designed to look at the effects of supplements on leukocyte telomere length. The analysis also excluded participants who did not have data on leukocyte telomere length. It's possible that unaccounted-for factors influenced the results, and the study also has any other limitations found in the original study. Regarding exploratory subgroup analysis results, researchers encourage caution, note limited power, and say people should look at the data as 'hypothesis-generating.' After four years, there were about 37% missing cases. Researchers acknowledge that this reduced power and could be why they did not find omega-3 fatty acid supplementation affected leukocyte telomere length. Future research can explore why vitamin D may have these effects on telomere length. For example, it could be related to an enzyme called telomerase that helps to lengthen telomeres and how vitamin D may protect against DNA damage. Cutler also noted the following limitations of the study: 'The present study involved only a relatively small number of people, looked only at telomeres in white blood cells, and did not look extensively at the health impact of these telomere changes. So, the clinical implications one can derive from this study are quite limited.' This study suggests the potential benefits of vitamin D in relation to aging. The authors suggest that the preservation of telomere length in this study 'could mean a 3-year decrease in aging.' 'As we know already, vitamin D supports bone, immune system and reduces inflammation, but this study is linked directly with telomere preservation which ties into aging and disease prevention. This [study] gives more of a general idea that vitamin D3 could do more than just helping your bones but actually slowing down the cellular age, impressive!' 'If this is confirmed in future studies, this could mean that daily [vitamin D} supplements could actually help reduce risks for age-related diseases. This is a door for new medical guidelines in the future and will be a huge deal for preventive medicine.' — Yoshua Quinones, MD However, it's also important to note the potential risks of vitamin D supplementation. 'While 2,000 units of vitamin D is unlikely to have any negative effects, there may be some risk to vitamin D supplements as they can cause kidney damage and other adverse effects in excessive quantities. Since vitamin D is fat soluble, it can accumulate in our bodies, causing toxicity. So, any potential, as yet unproven benefits of vitamin D need to be weighed against its known risks,' Cutler said.

An L.A. Doctor's House Burned. Now He Treats the Fires' Effects in Neighbors.
Dr. Ashraf Elsayegh's house was one of the first to burn. He stepped out into his backyard atop the Pacific Palisades in early January to find a raging fire leaping from three houses away to two. He gathered his family, helped older neighbors to their cars and fled without a single keepsake. In the days that followed, Dr. Elsayegh, a pulmonologist, did not have a chance to grieve. As he did his rounds with patients at Providence Saint John's Health Center in Santa Monica, Calif., his cellphone was bombarded with neighbors and friends seeking his expert advice. What kind of air purifier? Is an N-95 mask enough? My daughter has asthma — should we rent a place farther away? 'Forty phone calls a day with the same set of questions,' Dr. Elsayegh recalled. So when the chief administrative officer of the hospital invited him into his office to ask Dr. Elsayegh how he could support him and his family, Dr. Elsayegh replied instead, 'Let's open a clinic.' Just three weeks after the blaze tore through neighborhoods of Los Angeles, the hospital's urban fire clinic for pulmonary issues began seeing patients. They came in droves, each with a different set of symptoms and concerns. The clinic has served as an early indicator of the types of health problems developing among those exposed to the fires, ranging from newfound shortness of breath in healthy people to exacerbated symptoms in patients with asthma, C.O.P.D. and other lung diseases. The health effects of an urban fire differ from a those of a wildfire, and when an entire community burns quickly, releasing unquantifiable toxins in unexpected directions for an unknowable period of time, there are long-term health effects that no expert can yet fully calculate. Dr. Elsayegh is making it his mission to support patients from the Palisades and surrounding communities for months and years into the future, when, he fears, cleanup crew members and others with chronic exposure may begin to show signs of severe lung diseases, like asbestosis and silicosis, and even cancers like mesothelioma. Another long-term concern is pulmonary fibrosis, a progressive disease in which scarring thickens and hardens lung tissue, making it difficult for oxygen to move into the bloodstream. Dr. Elsayegh describes a lung with pulmonary fibrosis as 'a stiff balloon from the party store' — your face flushes as you try to force air inside, but it simply refuses to inflate. As a former Palisades resident intent on returning to the neighborhood, Dr. Elsayegh is also doubling as a trusted confidant, drawing on his personal experience to help his patients face uncertainties and find solutions — or next steps, at least. 'In an ideal world, I would go in there and say, 'Everyone that lives in the Palisades and in L.A. County, let's all move. Let's all go somewhere else and we don't have to worry about this,' ' he said. 'That's not reality. I'm trying to find this unbelievably difficult balance of helping us return to normalcy or return to our life, but doing it as safely as possible.' In early February, Dr. Elsayegh pulled up a chair next to Dana Michels, a cybersecurity lawyer and healthy mother of three who had gone to check the damage at her house and now could not shake a cough. 'Sweetheart, you're not moving air at all,' Dr. Elsayegh said, listening to her lungs through a stethoscope and quickly ordering a breathing test and a nebulizer, to start. A pulmonary student asked to take a listen, then glanced up at Dr. Elsayegh, looking confused. 'I'm not hearing anything,' the student said. Dr. Elsayegh gave a single nod. After years of renting, Ms. Michels and her husband got their first mortgage almost four years ago; it was a family milestone. Now, with their Palisades home smoked through, the family is split between two rental apartments in Marina del Rey — one for boys, one for girls — and they are navigating a new school, new insurance paperwork and new prescriptions to manage the wheezing. Another patient, Andrew Orci, was dealing with the effects of lung scars, which had resulted from cancer treatments more than a decade ago. Mr. Orci's family was staying in an Airbnb in West Hollywood, far enough from the debris to avoid dust plumes, but Dr. Elsayegh explained that he would still need to be on the lookout for severe shortness of breath in the coming months. His lungs were fragile, and his exposure to pollutants from the burning homes could significantly worsen the course of his condition. Waves of new patients in March and April showed toxins had made their way farther and farther from the Palisades, affecting people who had been nowhere near the fire's epicenter when it was raging. One person in Brentwood, about five miles inland, told Dr. Elsayegh that his bronchiectasis, a condition involving excess mucus in the airways, had worsened once trucks from the Palisades began driving through his neighborhood, hauling loads of debris. Barbara Effros, 67, already had chronic bronchitis when wind off the fire zone carried dust all the way to her windowsills in Culver City, about nine miles southeast. Now, Ms. Effros, who used to walk three miles per day, could hardly get from the car to the hospital check-in counter. 'It feels like I smoke a pack of cigarettes a day and I'm at 12,000 feet,' she said, 'like there's a clogged straw in my throat.' Dr. Elsayegh's mental framework for the pulmonary aftermath of the Palisades fire comes not from the burning of more than 5,000 buildings in Southern California but from that of an iconic two 3,000 miles away. On Sept. 11, 2001, Dr. Elsayegh was a medical resident in New York City. He remembers his hospital's mad rush that day to transfer all patients out of the city and make space for those injured from the falling World Trade Center towers, only to see their wards lie vacant through the night. 'Either you died, or you were relatively OK,' he said. It was only months after the attacks, when residents near ground zero had settled back into their apartments and workers had been inhaling dust and toxins in the pit, that a slew of patients began showing up at his hospital, complaining of shortness of breath. Jen Croft, who monitored the air quality in the Los Angeles area after the fires with the Interagency Wildland Fire Air Quality Response Program, said the destruction of Sept. 11 was not a perfect comparison, given the different materials, footprint and heat source, but that some elements of the aftermath would be similar. And indeed, Dr. Elsayegh is now beginning to see an uptick in patients coming through the clinic, including firefighters who are complaining of worsening asthma and other symptoms. He plans to visit firehouses throughout the region in May, measuring lung function in those who might still be putting off care. For a while, new marks of the disaster were everywhere Dr. Elsayegh looked. His medical assistant at the clinic suffered asthma attacks, calling in sick. Dr. Elsayegh needed to call pharmacies and remind them to contact patients instead of mailing prescription medicines to the home addresses on file, since many had burned down. After a catastrophe, doctors like Dr. Elsayegh sit at the nexus of physical and mental health care. Suicide rates typically surge after natural disasters, as do cases of anxiety, depression and post-traumatic stress, so Dr. Elsayegh often talks with his pulmonary patients about the trauma. 'I tell them, 'Don't forget: I'll take care of your lungs, but here are some ideas and some strategies, including therapists,'' he said. 'You need more than the 15 minutes they have with me.' Luciana Brafman, an environmental activist and film producer, came to see Dr. Elsayegh because she developed a grueling respiratory infection after driving into the Palisades while wearing only a surgical mask. But in the waiting room, her strongest concern seemed to be the broader effects of the crisis. Ms. Brafman described her ongoing film project about recent floods in Brazil and how it dovetailed with swirling fears about the effects of the Palisades fire on nearby marine life. She eventually needed medication to sleep but was still plagued by the same nightly dream: grabbing her son and running for cover. At the end of a long clinic day, Dr. Elsayegh sat with Susan Kanowith-Klein, an 80-year-old who felt physically fine — despite a history of pulmonary issues — but emotionally spent. Ms. Kanowith-Klein's home in the Palisades had survived the fire, but she wondered aloud about whether air quality test results were legitimate, whether hazardous soot meant she should relocate and, deep down, whether her community would ever be the same. She missed her water aerobics class and her yoga practice; she was in her fourth temporary living situation while she decided whether to move back. 'How's your home?' Ms. Kanowith-Klein asked Dr. Elsayegh, wiping away a tear. He answered simply, 'Gone.'
