There is a ton of info, just look around. Also, what is the common ingredient in all processed foods? This is what is making people fat. Omega-6 integrates in body fat, easily oxidized and unstable, rendering our own fat inaccessible for energy, so we're chronically hungry, tired, and inflamed. Than add in sugar and salt for hyperpalability. We've been hacked.
Seed oils are nothing more than industrial waste sold as food for profits.
This orthorexic behavior by labeling certain foods as unhealthy or healthy is the real problem.
Any kind of diet needs to be accompanied by a proper lifestyle. Eating a high calorie diet and then not having any physical activity is just asking for a bunch of metabolic issues.
Particular food item is not healthy or unhealthy, toxic or rejuvenating. It's the lifestyle+diet that can be labeled as healthy/unhealthy.
These are the worst ones: Canola, Corn, Cottonseed Soy, Sunflower, Safflower, Grapeseed, and Rice bran.
Also, olives and coconuts are fruits.
This idea that physical activity will balance out an unhealthy diet is wrong and has been proven wrong by decades of people attempting just that. It doesn't work. Once your metabolism is damaged by your diet, no amount of physical activity (if you can muster it) will fix it.
There's a bunch of papers on Neu5Gc, should I start being scared of meat toxicity?
Diet containing seed oils can be healthy. Nowhere have I made an argument that an unhealthy diet will be countered by physical activity.
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.
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.
Sufficient omega-3 intake doesn't entirely mitigate the ills from omega-6 anyway, and there are other toxins in seed oils as well.
