he last 100 years or so, people have increased their consumption of added fats. However, this is entirely explained by a drastic increase in the consumption of refined vegetable oils, such as soybean oil, corn oil, cottonseed oil and canola oil.
These oils are very high in omega-6 fatty acids, which humans never consumed in such large amounts before.
There are many serious concerns with these oils. They are highly sensitive to oxidation and cause increased oxidative stress in the body. They have also been linked to increased risk of cancer.
Alternatives: Use healthier fats like coconut oil, butter, extra virgin olive oil or avocado oil instead.
