Vegetable (and seed) oil is concerning because:
- It frequently comes from foods that really weren’t “meant” to produce oil. The prime example would be corn – a food that was predominately fiber, vitamins, and a little protein and fat. Imagine how difficult / how much work it would take to extract 1 liter of oil from corn…
- During that extraction, not that much vitamin E will be extracted. Vitamin E, an anti-oxidant, exists in foods high in omega 6 to protect the fats from oxidization.
- That processing (along w/ the more steps to make it palatable and pretty), storage for weeks/months/years in clear plastic, exposure to heat and light, etc, can oxidize the omega 6.
If you are eating a healthy balanced diet – eat foods that you could find in nature, in the quantities you could find in nature, as you could prepare in nature – there is really no reason to fear omega 6.
Certainly avoid omega 6 high oils such as corn, soy, canola, etc, but only b/c they are unstable & inflammatory chemically, provide little nutrition to start with, and go through more extensive processing that other foods.
But I would not worry about the omega 6 present in a couple handful of raw nuts a day…or found in 1 avocado…or even high quality olive oil, which will be cold pressed and still maintain some Vitamin E.
Where Do You Find the Most Vegetable Oil?
In prepared foods and restaurants they see a lot of use. In homes, it depends. Plenty of people still use generic store brand vegetable oil, which are typically soybean oil, and canola oil(including non-stick sprays like PAM), which has a moderate linoleic acid content and much higher than olive, palm, and coconut.
Olive oil sees heavy use among certain ethnic foods(Italian, Mediterranean) and coconut is rather new in the mainstream and doesn’t pair well with many foods because it does have a strong flavor(unlike canola, grape, olive, soybean, etc).
Effects of Saturated Fats on the Body
Dr Rhonda Patrick was explaining some of the biochem behind the effects of saturated fats on the body. She was describing how saturated fats are not bad for you by themselves, but when combined with eating lots of sugar it can cause the formation of Small Dense LDL Particles.
