    S01E07 | Mediterranean Diet: Can Olive Oil and Nuts Protect Your Heart?

    Can eating more olive oil, nuts, and vegetables really reduce your risk of heart attacks and strokes? In this episode of Health Without Homework, we explore the landmark PREDIMED trial, one of the most influential studies of the Mediterranean diet, published in the New England Journal of Medicine. Researchers followed more than 7,400 adults at increased cardiovascular risk and found that those assigned to a Mediterranean diet supplemented with extra-virgin olive oil or nuts experienced approximately 30% fewer major cardiovascular events compared with a group advised to reduce dietary fat. But what does that 30% reduction really mean? Do you need to eat four tablespoons of olive oil every day? And is the Mediterranean diet really better than simply eating less fat? We also explore the study's controversial history, why the original publication was withdrawn and revised, and what the findings mean for everyday eating. In this episode: What the Mediterranean diet actually includes What the PREDIMED trial discovered about heart health Why relative and absolute risk tell different stories What scientists learned from the study's methodological problems Simple, practical ways to incorporate Mediterranean-style eating into your routine No miracle foods. No complicated diets. Just science you can understand and use. Read the original research: Estruch R, et al.

    S01E06 | Food for Healthy Aging: What Should You Eat to Age Well?

    Can the foods you eat today influence how well you think, move, and feel decades from now? In this episode of Health Without Homework, we explore a fascinating 2025 study published in Nature Medicine that followed more than 105,000 adults for up to 30 years to investigate which eating patterns are associated with healthier aging. The researchers weren't just interested in living longer. They wanted to understand what helps people reach older age with their memory, physical abilities, mental health, and independence intact. In this episode, we explore: Which eating patterns were most strongly linked to healthy aging How Mediterranean, DASH, MIND, and other diets compare Why fruits, vegetables, nuts, beans, and whole grains matter What the research says about ultraprocessed foods Whether one diet is really better than the others Simple, affordable food choices that may support long-term health One surprising finding? People who followed the healthiest eating pattern had 86% higher odds of healthy aging compared with those who followed it least closely. But what does that number actually mean, and can we be sure food was responsible? We break down the research in plain English, separate evidence from hype, and discuss what you can take away for everyday life. No miracle diets. No complicated meal plans. Just science simplified.

    S01E03 | Do Social Media Warning Labels Work?

    What if Instagram, TikTok, and other social media apps came with health warning labels? In this episode of Health Without Homework, an ICU physician and a nurse break down a new randomized study published in JAMA Health Forum that tested social media warnings in 1,012 teenagers and young adults ages 13–29. Researchers compared warnings about mental health, depression and anxiety, sleep, body image, addiction, and other potential harms with a simple “take a break” reminder. The health-focused warnings were generally rated as more persuasive than a basic screen-time reminder, especially messages about mental health and depression and anxiety. But there is an important catch: the study measured how persuasive the warnings seemed—not whether people actually spent less time on social media or experienced better mental health. We discuss what the study found, what it did not prove, whether people might eventually tune warnings out, and what parents and everyday social media users can reasonably take away from the research.

    Why Do So Many People Stop Semaglutide? | S01E02

    Semaglutide and other GLP-1 medications have changed obesity treatment, but there is a less discussed question: what happens after people actually start taking them? In this episode of Health Without Homework, we break down a new nationwide study from Denmark that followed more than 157,000 adults who started semaglutide for obesity. By 12 months, about 49% had discontinued treatment, and roughly 1 in 4 people who stopped later restarted. We look at who was more likely to stop, why cost and side effects may matter, what the study can and cannot tell us, and why real-world treatment is often more complicated than simply being “on” or “off” a medication. The bigger question is not just whether semaglutide works, but whether people can realistically afford, tolerate, access, and continue it long enough to maintain the benefit. Study: Mailhac A, et al.
