Cyanide in apple seeds is toxic in proper amounts, should I avoid consuming apple seeds, or apples completely?
Toxicity of certain compounds in meat or other foods has nothing to do with the food itself being healthy or unhealthy.
Similarly how antioxidant, vitamin or macronutrient content has nothing to do with that particular food being healthy or unhealthy.
Promoting the idea that a particular food or ingredient is healthy or unhealthy is promoting orthorexic behavior, an obsession over what to include or not include in your diet because of a made up measure of (un)healthiness.
Here's a riddle for you: if seed oils were not toxic, why are mice given seed oils as low as 4-5% of calories in order to cause cancer in the presence of other carcinogens? They don't get cancer with the carcinogens alone, they have to add the seed oils to trigger the cancers.
There are similar studies on meat/Neu5Gc being combined with fibre to reduce the toxicity - more carcinogens present the less fibre there is.
There are similar studies on casein/whey.
These studies do not make meat, milk, cheese or seed oils inherently unhealthy or show that you can't have them as a part of a healthy diet.
edit: doing a quick Google Scholar search I can find a bunch of studies that show positive outcomes after regular consumption of flaxseed (rich in omega 3s) or pumpkin seed (rich in omega 6) oils. These studies do not make these oils healthier.
20g of flaxseed oil (180kcal) contains a bunch of ALA, pick a massively low conversion ration to DHA/EPA of 0.5% or 1% or whatever, and you'll see that you'll get very near if not over the recommended daily amounts of 250-750mg.
Maybe, I don't have the exact figure either but it is known that a specific mutation (which I don't have) is needed for efficient conversion. This is telling that at some rather recent point (agriculture) humans started consuming less animal fats.
