Ophthalmologist Chris Knobbe argues that excess omega-6 seed oils are a unifying cause of chronic diseases of civilization such as diabetes and macular degeneration. He presents the case at Low Carb Denver 2020.
HN commenters point to it in nutrition threads as the strongest case against seed oils, though it is a contested claim.

I think the best talk of the health dangers of seed oils is in the following video: Dr. Chris Knobbe - 'Diseases of Civilization: Are Seed Oil Excesses the Unifying Mechanism?' [1] If you're short on time, you can skip directly to the trials data section [2] 1. this video 2. this video
The idea that animal products are unhealthy seems to be misguided. It seems more likely that the supposedly "heart healthy" seed oils are causing heart disease. The Carnivore Code has some very good insights (at least in my opinion) [1] And this talk on how seed oils are destroying our health is also pretty interesting: this video [1] [LINK]
Recommended viewing: Dr. Chris Knobbe - Diseases of Civilization: Are Seed Oil Excesses the Unifying Mechanism? this video Here's a slide where he shows that soybean oil induces diabetes (in mice): this video The talk makes the case on how it's also applicable to humans.
Not all fats are created equal. There's data pointing that Omega-6 fatty acids (primarily vegetable/seed oils and trans fats) are harmful. See the following talk by Dr. Chris Knobbe: this video You can jump here for the studies: this video
> Animal feed is usually not suitable for human consumption, so while technically there would be an abundance of food, it would not be edible by humans. > For corn for example, 7% of the harvest is suited for human consumption. The efficiency coefficient is pretty terrible if we throw away the remaining 93%. We don't need to produce those 93% of corn at all. We can reforest fields/pastures used for meat production and store a busload of CO2 in the process - [LINK] > Farm areas that can grow human edible food tend to not be used for animal feed. I don't know ... 75% of fields are used for animal agriculture, so one can easily get to that conclusion, but in my experience, those areas are intermixed (is it a word?). [LINK] > The efficiency coefficient of food turned into compost is not that great with a lot of it turning into methane, get eaten by bacteria, and runoff into the oceans and water supplies. How much methane does composting produce depends on composting method, aerobic composting is significantly better in this regard and in the end, composting is better than putting the food/organic materials into landfills. Feeding the soil bacteria and enhancing the soil profile (with compost) is a good thing. We need more of those little critters. Not so sure about the runoff - I think that argument applies to pesticides/herbicides, where it's a big problem. Compost is an organic matter, a soil in the end - but soil erosion is a problem, so I tend to agree :) [LINK] > Vegetarian
