Seed oils have become one of the most argued-about ingredients in food. Some people avoid them completely. Many dietitians say the fear is overblown. Here's what seed oils are, what each side says, and how to avoid them at breakfast if you choose to.
What are seed oils?
Seed oils are pressed or extracted from the seeds of plants. The ones you'll see most on labels:
- Canola (rapeseed) oil
- Soybean oil
- Corn oil
- Sunflower and safflower oil
- Cottonseed oil
- Grapeseed and rice bran oil
Oils that come from a fruit rather than a seed, like olive, avocado and coconut oil, aren't seed oils.
The case against seed oils
People who avoid seed oils usually point to four things:
- Omega-6 fats. Seed oils are high in linoleic acid, an omega-6 fat. Critics argue that modern diets have far more omega-6 than omega-3, and that this imbalance drives inflammation.
- Industrial processing. Many seed oils are refined at high heat, and some are extracted with chemical solvents like hexane.
- Oxidation. Polyunsaturated fats break down more easily with heat, especially when oil is reused for frying.
- Where they show up. Seed oils are in a huge share of ultra-processed foods: chips, fried food, packaged snacks and many breakfast products.
What the research says
Many nutrition researchers don't think seed oils themselves are harmful. A review of the evidence from the Academy of Nutrition and Dietetics found that:
- Randomized trials haven't shown that linoleic acid raises inflammation markers in people.
- Replacing saturated fat with seed oils tends to improve cholesterol levels.
- Solvents like hexane are almost entirely removed during refining.
The 2025–2030 Dietary Guidelines for Americans take a middle path. They list non-seed oils like olive oil as the preferred choice for cooking, and name butter and beef tallow as options too. They don't tell people to avoid seed oils outright.
Our take
The science on seed oils themselves is still debated, and we're not going to tell you they're poison. But both sides tend to agree on one thing: seed oils are everywhere in ultra-processed food. Cutting them out tends to cut out a lot of that food too.
That's why we keep Beef Cakes simple. Our pancake and oatmeal cups use coconut oil or no added oil at all, with organic whole grains and collagen protein.
How to skip seed oils at breakfast
- Read the ingredient list, not just the front of the box. Look for the oils listed above.
- Watch "vegetable oil." It's usually soybean or a blend of seed oils.
- Cook with olive oil, avocado oil, butter or coconut oil at home.
- Check packaged pancake mixes, granola and breakfast bars. Many include canola or sunflower oil.
Every Beef Cakes cup is seed-oil-free. See exactly what's in each one on our seed-oil-free breakfast page.
Quick answers
Are seed oils bad for you?
The research is debated. Reviews of randomized trials haven't found that seed oils raise inflammation markers, and replacing saturated fat with them tends to improve cholesterol. Many people still limit them, partly because they're common in ultra-processed foods.
Is coconut oil a seed oil?
No. Coconut oil comes from the fruit of the coconut, not from a seed oil crop like canola or soybean.
Is olive oil a seed oil?
No. Olive oil is pressed from the olive fruit. The 2025–2030 Dietary Guidelines list non-seed oils like olive oil as the preferred choice for cooking.
Do Beef Cakes contain seed oils?
No. Beef Cakes cups use coconut oil or no added oil at all.
