Do vegetable & seed oils cause inflammation?

We try to be aware of the past and present books available on topics. Some of us really like reading. I am sure some are 100% convinced vegetable/seed oils in all amounts cause a HUGE amount of inflammation. But what does the science suggest?

Diving into the research. You asked, and we're responding.

The arthritis foundation has stated that these oils taken in excess trigger pro-inflammatory chemicals. Their conclusion is, "They aren’t especially bad and shouldn’t be avoided, but you don’t want them to dominate your intake."

Will using less than 100 mg per day of organic sunflower oil, listed under "Other Ingredients" on a supplement facts panel, elevate your inflammation?

The data says, "No."

(1) This amount is not considered excessive.
(2) It is not heated.
(3) The amount is not significant enough to modify the Omega-6/Omega-3 ratio. Further, many of us are increasing omega-3 fats with chia seeds, flaxseeds, fish, etc.
(4) This sunflower oil is not ultra-processed and is not being delivered in ultra-processed foods known to also cause inflammation.

As with many aspects of diet, it's important to consume vegetable oils and seed oils in moderation.

Some might argue that "even a little vegetable oil & seed oil daily" is akin to "death by a thousand cuts." What does the data say? In the case of vegetable oils & seed oils, small amounts offer health benefits:
(1) Heart health
(2) Decrease risk of diabetes
(3) Decrease inflammation

"Seed oils are high in omega-6 fatty acids, a type of polyunsaturated fat that isn’t necessarily bad for you. In fact, your body needs a little bit of them! In small amounts, they’re good for your cholesterol and help protect you from heart disease."
