Science You Can Use: Butter, Brisk Movement, and a Fruit for Better Sleep

A new Science You Can Use episode — three studies that translate into simple, real-world steps you can take today. In this episode, Dr. Wendy Bazilian brings evidence to life with approachable explanations, practical tips, and the kinds of changes that actually fit into your day.

Whether you’re a nutrition pro, wellness enthusiast, or just someone trying to feel a little better each day, you’ll walk away with useful, doable takeaways.

Study 1: Plant-Based Oils and Mortality SuZhang Y, Chadaideh KS, Li Y, et al. Butter and Plant-Based Oils Intake and Mortality. JAMA Intern Med. 2025;185(5):549–560. doi:10.1001/jamainternmed.2025.0205

• Summary: Higher butter intake was linked to a 15% increased risk of total mortality; higher plant-based oil intake (olive, avocado, chia, walnut) was linked to a 16% reduced risk. Just two teaspoons a day of plant-based oil instead of butter was associated with a 17% lower risk of death.
• Practical Tip: Swap in olive, avocado, or chia oil for sautéing or dressings a few times a week.
