Seafood Lovers Beware: Study Links PFAS Chemicals to High Consumption

Published

on

A recent study has raised concerns about the potential exposure to harmful chemicals, specifically PFAS, from frequent seafood consumption. These toxins, often referred to as “forever chemicals,” persist in the body indefinitely once ingested.

The study, published in Exposure and Health, suggests that regular seafood eaters may be at a higher risk of exposure to these chemicals, which have been linked to a range of health issues, including cancer, fetal abnormalities, high cholesterol, and thyroid, liver, and reproductive disorders.

The research team conducted a detailed analysis of PFAS concentrations in fresh seafood and surveyed eating habits in New Hampshire, a state known for its high seafood consumption. They tested 26 types of PFAS in the most commonly consumed fish: cod, haddock, lobster, salmon, scallop, shrimp, and tuna. The results revealed that shrimp and lobster contained the highest levels of PFAS compounds.

“The scientific community is working hard to understand more about the overall risk-benefit tradeoff of consuming seafood,” said Megan Romano, PhD, an associate professor of epidemiology at Dartmouth’s Geisel School of Medicine. “Part of the current challenge for consumers is that some of the traditionally safer seafood choices in terms of mercury content may have higher concentrations of other pollutants, like PFAS.”

The study’s findings have underscored the need for more stringent public health guidelines regarding seafood intake, particularly in coastal areas with PFAS pollution. Kathryn Crawford, the first study author and an assistant professor of environmental studies at Middlebury College, emphasized that exposure to PFAS via seafood is a function of both the amount of seafood people eat and the concentrations of PFAS in seafood.

“We found that people in NH consume more seafood on average than other parts of the U.S. Also, the region has been home to PFAS-related industries, which can release PFAS into the environment that can ultimately bioaccumulate in organisms like fish and shellfish,” Crawford added.

The study’s findings suggest that people in areas with PFAS pollution and high seafood consumption may be exposed to more PFAS than elsewhere. This has led to calls for the development of public health guidance for seafood consumption that takes these findings into account.

“There needs to be more awareness and strict guidelines on what is considered safe with these chemicals,” said Julia Zumpano, a registered dietitian with the Cleveland Clinic center for human nutrition. “People should limit known sources or PFAS in non-stick cookware, personal care products, cleaning products, grease resistant products, water resistant fabrics, stain resistant products.”

Pregnant individuals and children are particularly vulnerable to excessive seafood consumption. “Pregnancy and early childhood are periods of rapid development with a person’s life, which makes them susceptible to chemical exposures that might interfere with these normal developmental processes,” Crawford said.

David Love, PhD, an expert in food systems and sustainability and associate professor at John Hopkins Bloomberg School of Public Health, explained that pregnant and nursing individuals and young children cannot tolerate chemicals found in certain types of seafood, especially when consumed in large amounts.

Experts agree that the findings of the new study add to our understanding about the risks of PFAS exposure. David Love said, “PFAS is an emerging risk that we should be aware and continue to monitor and evaluate, but we are not yet able to set national guidance for seafood.”

For the general public, seafood should be limited to about 12oz per week, but fish high in mercury should be consumed less frequently, according to Zumpano. She also recommended choosing fish from the ‘best choices’ list most often, limit fish from the ‘good choices’ list and avoid fish in the high mercury list.

“Choose low mercury canned tuna, ideally that has been tested for mercury content,” Zumpano said. This study highlights the importance of a balanced diet and the need for consumer-friendly recommendations about seafood consumption.

Urgent Alert: Major Recall on Popular Herbal Supplements Due to Undisclosed Drug Risks

Published

on

By

People across the United States often take supplements to boost their health, but it’s crucial to remember that the U.S. Food and Drug Administration (FDA) does not give pre-market approval for dietary supplements. Consequently, if safety issues surface, they typically arise after consumers have already had the chance to purchase and use the products. Currently, this situation is unfolding as two separate supplements are being recalled due to undisclosed drug ingredients.

The FDA recently disclosed a company announcement regarding the first of these supplement recalls. The announcement, made on July 15, concerns a voluntary recall by SoloVital.com, a California-based company, of all batches of its Umary Acido Hialuronica (Hyaluronic Acid) supplements. This product, promoted and sold for pain relief, is distributed nationwide via the company’s online store.

“The recall was ordered after an FDA laboratory analysis confirmed that the Umary supplements were tainted with two hidden drug ingredients: diclofenac and omeprazole,” according to the recall notice.

“Products containing diclofenac and omeprazole cannot be marketed as dietary supplements.”

Diclofenac is a non-steroidal anti-inflammatory drug (NSAID). It can “cause increased risk of cardiovascular events, such as heart attack and stroke, as well as serious gastrointestinal damage, including bleeding, ulceration, and fatal perforation of the stomach and intestines,” warns the FDA. There may also be harmful interactions with other medications, particularly if consumers use multiple products containing NSAIDs.

On the other hand, omeprazole is a proton pump inhibitor (PPI) typically used to treat stomach acid-related disorders. However, it “may cause serious skin reactions, abdominal pain, diarrhea, nausea, and headache,” according to the FDA. This surreptitious ingredient can potentially camouflage stomach problems and may negatively interact with other medications.

SoloVital is currently contacting its customers via email to arrange product returns. In the meantime, consumers who have the affected Umary supplements are being strongly advised to cease usage and return them to their original place of purchase.

Yet, there’s a second supplement of concern that might be in your household. Following closely on the heels of the Umary recall, the FDA released another company announcement about another supplement recall on July 16. This one concerns the voluntary recall of some Infla-650 Herbal Dietary Supplement Capsules by Guru Inc., a Georgia-based company.

These Infla-650 Herbal supplements were also found to contain hidden diclofenac. In addition, they also included undisclosed acetaminophen and phenylbutazone. This poses a significant risk to consumers due to the danger of unintentional acetaminophen overdose, especially if consumers are also taking other products containing acetaminophen.

“Acetaminophen overdose can cause liver damage (hepatoxicity), ranging in severity from abnormalities in liver function to acute liver failure, and even death,” according to the recall notice. Furthermore, the presence of phenylbutazone, an NSAID previously discontinued for human use in the U.S., is concerning due to its risk of causing potentially fatal injuries, specifically bone marrow toxicity.

The recalled Infla-650 supplements, marketed as an herbal dietary supplement for pain relief, were distributed nationwide and sold online. Like SoloVital, Guru Inc. has initiated communication with its distributors and customers for product return. Consumers are urged to stop use and return any recalled Infla-650 supplements to their place of purchase.

Gastroenterologist’s Top 5 Foods for a Happier, Healthier Gut

Published

on

By

The health of our gut is pivotal, playing a significant role in our overall wellbeing by processing food, absorbing necessary nutrients, and expelling toxins. As noted by internal medicine physician William W. Li, MD, “The more diverse your microbiome, the healthier your gut. This translates into lower inflammation and a reduced risk for chronic diseases like heart disease and type 2 diabetes. It can also promote faster healing, a more streamlined metabolism and even better mood.” So, what foods nurture the gut and boost its health? Here are five gut-friendly foods that gastroenterologist Joseph Salhab, DO, incorporates into his daily diet.

Sourdough Bread

Dr. Salhab, an avid baker, champions sourdough bread as a gut-friendly food. “For my gut-friendly breads, I love sourdough,” says Salhab. He explains that sourdough is “lower in gluten and other bloat-causing agents than other breads,” making it a healthier choice for your gut. The fermentation process of sourdough also leads to an increase in prebiotic and probiotic properties, which benefit the gut’s health, per a 2021 report in the journal, Microorganisms.

Kefir Cheese

After toasting a slice of his homemade sourdough bread, Salhab enjoys it with a thin spread of kefir cheese. This cheese is “naturally rich in probiotics,” which are great for gut health. Kefir, a fermented milk-like beverage, boasts several health benefits, including “anti-inflammatory, anti-oxidative, anti-cancer, anti-microbial, anti-diabetic, anti-hypertensive, and anti-hypercholesterolemic effects,” according to a study in the Foods journal.

Greek Yogurt

When he’s not enjoying his sourdough toast, Dr. Salhab starts his day with Greek yogurt as it is a food naturally high in probiotics. He garnishes it with blueberries and raspberries, which he says, “help my gut bacteria thrive and they help with memory and focus.”

Avocados

Dr. Salhab cherishes avocados, a food high in fiber and packed with essential nutrients. As per Johns Hopkins Medicine, avocados promote healthy digestive function due to their potassium content. Plus, avocados are a low-fructose food, which helps to reduce bloating.

Sliced Tomatoes

With his sourdough toast and smashed avocado, Salhab adds slices of tomatoes, a “great prebiotic.” As outlined by Best Life, prebiotics serve as food for the gut’s microflora, differing from probiotics as they remain in the gut. Tomatoes can also lower your risk of heart disease, cancer, and boost immunity, as per Cleveland Clinic.

After discussing these gut-friendly foods, it’s clear that maintaining a healthy gut contributes to our overall health and wellbeing. By incorporating nutritious and diverse foods like sourdough bread, kefir cheese, Greek yogurt, avocados, and tomatoes into your diet, you can support a healthier, more diverse microbiome. As Dr. Salhab demonstrates, these foods can be delicious and provide a variety of other benefits, ranging from improved memory to reduced risk of chronic diseases. So, why not consider including them in your meal plan to help your gut strive?

Unlock the Secret Perks of Echinacea From Immune Support to Skin Care

Published

on

By

Introducing the multifaceted supplement that’s been revered for centuries for its potential health benefits: Echinacea. Once employed as a versatile medicinal herb to fight off diseases like scarlet fever and diphtheria, echinacea is now classified as a dietary supplement meant to enhance your overall well-being, not cure ailments. Many tout echinacea as a formidable immune booster, but the benefits don’t stop there. So, let’s delve into six surprising health benefits that echinacea supplements can provide.

Potential Anti-Inflammatory Properties

“Echinacea’s potential to reduce inflammation in the body is intriguing. It could help with minor skin irritation or sore throats by calming the body’s inflammatory response,” shares Raj Dasgupta, MD, a medical reviewer for NCOA. While research is underway to confirm the extent of these benefits, the initial anecdotal evidence is promising.

Speeding Up Wound Recovery

Echinacea isn’t just potentially beneficial internally, but externally as well. A 2023 study in the Molecules journal revealed echinacea’s antimicrobial and aseptic effects, which can aid in faster wound healing by warding off infections.

“It works by stimulating the immune system to send healing cells to the injured area,” explains Dasgupta. Nonetheless, he emphasizes that further research is needed and that echinacea should not substitute proper medical treatment for wounds.

Dermatological Effects

Your skin might love echinacea, too! A 2010 study identified echinacea purpurea as beneficial for protecting skin from oxidative stress and improving its hydration.

“Studies suggest it may be helpful for chronic conditions like eczema,” Dasgupta adds. Still, a call for more research to confirm this has been echoed.

Immune System Booster

Perhaps the most well-known potential benefit of echinacea is an immune system boost. Despite traditional use, Dasgupta urges caution, saying, “While traditionally used for colds, the evidence for its effectiveness is mixed. Some studies show a slight reduction in cold duration.”

Anxiety Alleviation

Could echinacea play a role in managing anxiety? A 2021 study found anti-anxiety and anti-depressant effects in subjects who took echinacea supplements for six weeks. Chris Mohr, PhD, RD, a fitness and nutrition advisor, explains, “It has potential anti-inflammatory properties, and chronic inflammation is linked to anxiety.” He does stress that it shouldn’t be used as a first-line anxiety treatment, however.

Regulating Blood Sugar Levels

There’s preliminary research suggesting that echinacea might assist blood sugar regulation, although this data is based on animal studies and has not been replicated in humans yet.

“If data do emerge to support the animal studies, this could be beneficial for those with prediabetes or those who need to manage blood sugar as part of a larger health plan,” proposes Mohr.

Echoing what might be the golden rule of dietary supplementation, our health journey is as unique as we are. What works for one may not work for all. So always be sure to consult with a healthcare provider, especially if you have chronic diseases or autoimmune conditions, before incorporating echinacea or any new supplement into your diet. From potentially reducing inflammation to possibly boosting your immune system, the old yet new echinacea might just be the versatile dietary supplement your health routine needs.
