Spring Allergy Guide: Pollen Forecast, Peak Times And Relief Tips
Spring tends to bring a surge in pollen, triggering allergies for millions of Americans.
Understanding when different types of pollen are at their highest can help allergy sufferers prepare and manage their symptoms effectively. Here's a breakdown of peak pollen times and triggers to watch for this spring:
Tree pollen is the first major allergen of the season, typically peaking in late winter through early spring (February to May, depending on location). Common culprits include oak, maple, birch, cedar, and pine trees. Warm, dry, and windy days exacerbate tree pollen levels, while rainy days can help clear the air.

Grass pollen takes over as tree pollen levels wane, with peak levels occurring from late spring into early summer (April to June). Bermuda, ryegrass, Timothy, and Kentucky bluegrass are common offenders. Grass pollen is particularly potent on warm, breezy afternoons.
Ragweed pollen is most notorious in late summer and fall (August to November). This resilient plant thrives in rural and urban areas alike, and a single plant can release billions of pollen grains into the air on a windy day.

Mold spores can trigger allergies at any time of year but spike in the spring and fall due to an increase in moisture. As melting snow, spring rains, and rising temperatures create damp environments, mold thrives in leaf piles, soil, and decaying wood. Unlike pollen, mold spores remain active in cool, humid conditions, making them a year-round concern for some allergy sufferers.
Researchers from the American College of Allergy, Asthma and Immunology found that pollen levels are lowest between 4:00 a.m. and noon, making early mornings the best time for allergy sufferers to go outside. In contrast, pollen counts peak between 2:00 p.m. and 9:00 p.m., so limiting outdoor activities during those hours can help to reduce symptoms.
Websites and apps can also alert you to high pollen days to help you plan accordingly. By staying informed about peak pollen behavior and taking preventive measures, allergy sufferers can better navigate the season with fewer flare-ups.

How thousands of unreviewed ingredients got into our food — and what FDA can do about it
At least 1,000 ingredients in food products on our grocery store shelves have never been checked for safety by the Food and Drug Administration. Dozens have raised serious safety concerns among experts. How did the FDA allow this? The answer can be found in the agency's lax interpretation of a little-known legal designation that lets companies decide for themselves if ingredients in their products are safe. Fortunately, there are steps the agency can take right now to stem the flow of potentially unsafe ingredients into our food supply. Environmental Defense Fund outlined these steps in a letter we recently sent to the agency, but first let's take a closer look at how we got here. 'Generally Recognized as Safe' is a designation Congress created in 1958 to allow commonly used food ingredients to bypass the FDA's pre-market safety review process. It was meant for food substances — such as oils, vinegar, baking soda and common spices — that were widely considered safe due to their long history of everyday use. Since 1958, this status has been coopted to cover a universe of foods that extends far beyond its original intent. According to FDA regulations, a chemical can receive the designation if experts widely agree that scientific evidence shows its use to be safe. But because 'Generally Recognized as Safe' wasn't meant for newer ingredients, Congress allowed ingredients so designated to skip the FDA's premarket approval process — despite requiring similar evidence for other additives. Under the agency's current interpretation, companies can designate the use of a substance as safe and take products with that substance to market without informing the FDA or the public of its decision. While companies may voluntarily submit a notice to FDA offering safety evidence, they are not required to — and often don't. Our organization estimated that manufacturers have notified FDA of fewer than half of the ingredients they market as safe under the 'Generally Recognized' standard. Companies that do bother to submit a notice to the FDA are free to withdraw it at any point and take their product to market, provided they can cite evidence of its safe use. But this 'evidence' is often far from independent. Companies can, and often do, enlist their own employees or handpicked consultants to conduct their safety assessments. The result is a process riddled with conflicts of interest that lets unsafe foods into Americans' homes. We analyzed 'Generally Recognized as Safe' notices received by the FDA, obtained via a Freedom of Information request, and found that of the 1,163 submitted by companies between 1997 and April 2024, 192 were later withdrawn, with safety concerns cited in at least a dozen cases. We also identified 31 ingredients that companies have advertised to be recognized as safe, such as in press releases, trade publications and on their own websites (see the Appendix of our letter). However, we were unable to find the scientific evidence required under this standard to demonstrate these ingredients are commonly regarded as safe among experts. This raises red flags that FDA should be taking seriously. Although a comprehensive fix to the 'Generally Recognized' standard will require legislation from Congress, there are significant steps the FDA can take right away to ensure a more rigorous determination process that better protects Americans' health. Starting today, the FDA can use existing authority to remove safe designations from ingredients it deems unsafe and take them off the market. It can also notify manufacturers, importers, distributors and retailers that the substance is no longer recognized as safe. In addition, the FDA can enforce the requirement that companies base safety designations on publicly available data. Although this won't curtail companies' ability to self-declare substances as safe, it will require those who do to be transparent in citing their evidence. Third, the FDA can enforce the requirement that safety assessments consider vital health information such as a substance's dietary sources, potential cancer risks and the cumulative health effects of similar substances. Finally, the FDA can make companies revise and resubmit their data for review when they submit 'Generally Recognized as Safe' notices that fail to comply with the criteria. The 'Generally Recognized as Safe' designation is far from a perfect system, but it can work better if it is interpreted and enforced more comprehensively. If the FDA is serious about protecting public health, it should start by fully exercising the tools already at its disposal.

Eating more of these plant-based foods could lower your risk of heart disease and diabetes
Eating more nuts, fruits, vegetables, and whole grains may help to reduce your risk of contracting deadly heart disease and type 2 diabetes. Researchers said this week that people who consumed more phytosterols — a natural compound found in plant foods — significantly delayed both of the conditions. Furthermore, eating more of them was linked to reduced inflammation, markers of better insulin regulation, and differences in the gut microbiome that may contribute to healthy metabolism. The study was not designed to confirm why this is the case, but the researchers said their findings strengthen the evidence. More than 7000,000 Americans die from heart disease and some 101,000 die from diabetes. 'Our findings support the dietary recommendation of adhering to healthy plant-based dietary patterns that are rich in vegetables, fruits, nuts and whole grains,' Dr. Fenglei Wang, a research associate at the Harvard T.H. Chan School of Public Health, said in a statement. 'These findings can help people make informed dietary choices.' Wang presented the observational findings on Tuesday at the flagship annual meeting of the American Society for Nutrition. Some phytosterol-rich foods include corn, almonds, broccoli, bananas, and wheat bread. Previous research had found that eating foods with phytosterols can help to improve peoples' health by lowering bad cholesterol, and may reduce the risk of cancer. However, most clinical trials have used high doses of the phytosterols that were beyond what someone might get through just their own diet. The new research is the first to show the benefits as part of a normal diet. To reach these conclusions, Wang and his colleagues looked at data from more than 200,000 American adults that were a part of three studies. All of the participants were nurses or other health professionals and nearly 80 percent were women. Over the course of 36 years, more than 20,000 of them developed type 2 diabetes and nearly 16,000 developed heart disease. The participants' answers to food-frequency questionnaires allowed the researchers to estimate their individual intake of phytosterols, as well as three individual phytosterols known as β-sitosterol, campesterol and stigmasterol. Those who ate the most consumed the most phytosterol had about four to five servings of vegetables, two to three servings of fruits, two servings of whole grains, and half a serving of nuts each day. This made them 9 percent less likely to develop heart disease and 8 percent less likely to develop type 2 diabetes compares to those in the bottom fifth percentage for phytosterol intake, the research showed. Looking at the individual phytosterols, similar associations were observed for β-sitosterol. But, the same was not true for campesterol or stigmasterol. In addition, the researchers analyzed blood samples, looking at the products of metabolism — also known as metabolites — from more than 11,000 people and other metabolic biomarkers in blood samples from over 40,000 participants. They found that phytosterol and β-sitosterol levels were tied to favorable metabolites and metabolic markers relevant to heart disease and diabetes. That signaled a possible reason for the association. 'Our clinical biomarker and metabolomic results suggest the involvement of insulin activity, inflammation and the metabolism of metabolites associated with type 2 diabetes and cardiovascular disease,' said Wang. 'This suggests that phytosterol might reduce risk by alleviating insulin resistance and inflammation.' In a group of just 465 participants, they examined the gut microbiome, or the trillions of microscopic organisms inside the intestines. They found several microbial species and related enzymes linked to higher intake of phytosterols that may affect the production of metabolites associated with a lower risk of diseases. 'We found that the gut microbiome might play a role in the beneficial associations. Some species, such as Faecalibacterium prausnitzii, carry enzymes that could help degrade phytosterol, potentially influencing host metabolism,' Wang said.

The Bulletin June 4, 2025
The rundown: Health and Human Services Secretary Robert F. Kennedy Jr.'s vow to "Make America Healthy Again" could fall short when it comes to chronic disease, experts have warned. Here's how. Why it matters: Nearly 130 million Americans are estimated to have at least one form of chronic disease, which could be heart disease, cancer, diabetes, obesity or hypertension, according to the Centers for Disease Control and Prevention. The proposed cuts to Medicaid funding and work requirements for eligibility to the benefits, which are set to come as part of the broader GOP budget bill, could leave many with chronic disease without access to vital care. As many as three in four adults enrolled in Medicaid report having one or more chronic conditions, and many are unable to work the hours needed to meet the new eligibility requirements, according to nonprofit health policy research and news organization, KFF. So, while some may be medically exempt, others will lose their health coverage, meaning their conditions could worsen without access to care. Read more in-depth coverage: Health Experts Call Out RFK Jr. Policy Changes: 'New Inconsistency Every Day' TL/DR: Experts told Newsweek that, while the Trump administration's ambition to "defeat" the "epidemic" is clear, whether its policies will help or hinder chronic-disease patients remains to be seen. What happens now? Ross Brownson, director of the Prevention Research Center at Washington University in St. Louis, Missouri, told Newsweek that Medicaid cuts would "likely have a detrimental effect on chronic disease risk among the most vulnerable populations," adding Medicaid-enrolled adults have significantly higher rates of chronic disease than individuals privately insured.
