Understanding Seed Oils: What You Need to Know

Why Routine Matters

Health advice is everywhere online—and not all of it is accurate or helpful. One topic that’s been popping up a lot lately is seed oils. You’ve probably heard influencers or read wellness trends warning people to avoid oils like canola, corn, soybean and peanut oil, suggesting they cause inflammation and other health issues. As a result, some people cut them out of their diets completely. But are seed oils really the villains they’re made out to be? Let’s take a closer look.

Not all oils are bad—in fact, many contain fats that our bodies need to function properly. Most oils (including seed oils) are made up of a mix of different types of fat, and when used in moderation, they can absolutely be part of a healthy diet.

The key is balance. Cooking with oils occasionally and using appropriate portion sizes is typically okay, especially when your overall diet is rich in whole foods like fruits, vegetables, lean proteins and whole grains (unless advised otherwise by your doctor).

Seed Oils and Processed Foods

Seed oils are often found in processed foods, such as chips, packaged snacks, fast food and baked goods. These foods also tend to be high in added sugar, sodium and refined carbohydrates.

So, if someone stops eating seed oils and starts feeling better, it might not be just because of the oils. Today’s Dietitian points out that the real benefit may come from cutting back on ultra-processed foods. In other words, people often feel better because they’re eating more real, whole foods, not just because they removed seed oils.

The Bottom Line

Your body needs healthy fats to function—and seed oils can be one of many sources. The goal isn’t to avoid all oils, but to use them in moderation as part of a balanced and nutritious diet. Before making significant changes to your eating habits based on trends, it’s best to look at the bigger picture and rely on trusted, evidence-based sources.
