Introductions

Myth-Busting Seed Oils
So in terms of the science, vegetable oils, which includes industrial seed oils, reduce cardiovascular disease risk, they lower all-cause mortality, and they at least modestly lower breast cancer risk, doesn’t seem to affect other cancer incidents very much. But breast cancer there does seem to be a signal. What matters is that we’re getting enough Omega 3s, not the Omega 3 relation to Omega 6, and we definitely want to be making sure we’re getting enough Vitamin E. – Dr. Sarah Ballantyne, PhD
In addition to two comprehensive articles about seed oils written by both Stacy and Dr. Sarah, listen as they tackle the following myths with science-supported facts:
- The consumption of industrial seed oils represents an evolutionary mismatch.
- Eating industrial seed oils raises our omega-6-to-omega-3 fatty acid ratios, with significant consequences for our health.
- Industrial seed oils are unstable and oxidize easily.
- Industrial seed oils are unstable and oxidize easily, processed with harsh solvents, deodorized, and chemicals added to improve color and smell.
- When industrial seed oils repeatedly cycle up and down in temperature (as restaurants do in fryers), even more toxic byproducts form.
- All seed oils are derived from genetically modified crops.
