About ten years ago, some fifty years after concerns were first raised about a possible link between trans fats and heart attacks, the U.S. Food and Drug Administration (FDA) ruled that partially hydrogenated oils, the primary dietary source of trans fats in ultraprocessed food items, were no longer “generally recognized as safe” in human food. Processed food manufacturers were given three years to reformulate their products or to request an exemption. This action was predicted to prevent thousands of fatal heart attacks a year. Multiply that by 50 years to get an idea of the effect trans fats have on your heart. Continue reading

About Omega-3s and Omega-6s
This week I’d like to share some of the things I’ve learned about two specific polyunsaturated fatty acids, omega-3 and omega-6 fatty acids.
Let’s start with omega-3 fatty acids. These are compounds in the form of a long chain of carbon molecules with several double bonds, each of which acts as a pivot point. Flexible pivot points confer the ability to move in many directions, essential for movement and flexibility. Omega-3s owe their flexibility to all those double bonds, the last of which is located just three carbons from the tail, or omega, end of the molecule. That’s why it’s called an omega-3 fatty acid. Omega means end. In contrast, omega-6 fatty acids contain fewer double bonds, and the last one is located six carbons from the tail. Hence, omega-6. Continue reading
