Before beginning his tenure as secretary of the United States Department of Health and Human Services, Robert F. Kennedy Jr. posted an old picture of his father, Bobby Kennedy, and another man at a drive-in fast food restaurant on the social media platform X. RFK Jr. took the family photograph as an opportunity to rail […]
If the new Dietary Guidelines for Americans (DGA) 2025-2030 report has taught us anything so far, it’s that people love to argue about food as much as they love to argue about politics. And given that the Guidelines–jointly issued on January 7, by the Department of Health & Human Services and the Department of Agriculture—is […]
GLP-1–based therapies, including glucagon-like peptide-1 receptor agonists (e.g., semaglutide), dual incretin agonists (e.g. tirzepatide), and forthcoming GLP-1–modulating drugs like retatrutide, have rapidly reshaped the clinical management of obesity, type 2 diabetes, and cardiometabolic disease. In less than a decade, these drugs have moved from the weight management and endocrinology niches to much wider use in […]
(This article was originally published on Dec. 3, 2025 on Undark.) For decades, U.S. marriage rates have been on the decline while the average age at which Americans have children has risen. Alongside this, birth rates have dropped — a phenomenon the Health and Human Services Secretary Robert F. Kennedy, Jr. has called a “national […]
(This article was originally pubished on Dec. 11, 2025, on Undark) For decades, the treatment of clinical depression has followed the same outdated flow chart: Try one antidepressant, then another, then a combination, then maybe just one more. Finally, when all pharmaceutical attempts fail, consider other approaches. This protocol, called step therapy, has come under […]
Autoimmune diseases disproportionately affect women. This is especially true for lupus (formally known as systemic lupus erythematosus), as about nine in 10 people with the condition are female. Lupus can cause inflammation and pain and commonly affects the skin, joints, and organs including the heart and kidneys. Scientists have long observed an association between infection […]
In a move that could out-MAHA MAHA, the City of San Francisco is suing Kraft Heinz, Coca Cola, Nestle, Kellogg, and six other producers of ultra-processed junk foods, claiming the companies have knowingly “engineered a public health crisis” by marketing highly addictive, nutrient-poor, sugar- and salt-laden foods linked to higher incidence of diabetes, fatty liver, […]
It takes gumption to cold-call the co-discoverer of the DNA double helix and ask him if he’d be willing to take a look at the anti-cancer potential of a food-derived natural product. David Wales and Rick Jahnke, the co-founders of American BioSciences, did just that back in August 2009, when they emailed James Watson, chancellor […]
Extensive research over the past several decades has revealed a dynamic connection between the gut and the bones. It turns out that bone health and strength is closely tied to the health of the digestive system. Gastrointestinal disorders contribute to the development of osteoporosis and, by extension, risk of fractures. This line of research suggests […]
For overweight people, diet-based weight loss interventions are a critical factor in restoring health. But dieting alone without concurrent exercise—which is the reality for many—results in loss of skeletal muscle along with the fat. And that can be very problematic. Some studies indicate that loss of fat-free mass (aka muscle) accounts for between 25%–30% of […]
