2. The Shocking Truth About Seed Oils and Their Impact on Our Health

Healthy AF | Healthy After 50

Today we are tackling a very important topic - seed oils and their impact on our health. As you probably know, seed oils are also known as vegetable oils, and they're everywhere in processed foods and restaurants.

The top ones to watch out for are soy, safflower, sunflower, corn, cotton seed, canola, grape seed, and rice brown oils. These oils are high in linoleic acid, an omega-six fatty acid that's been linked to the rise in obesity, type two diabetes, heart disease, and non-alcoholic fatty liver disease.

Dr. Kate Shanahan, who is one of the first to raise the alarm about the negative impact of these oils, has coined the term "hateful" for these oils. And it's no wonder - these oils are incredibly high in linoleic acid compared to the traditional fats we've been using for thousands of years. In fact, linoleic acid has increased from 9% of our body fat in 1959 to 22% in 2008, which can only come from our diets.

The problem with these seed oils is that they're relatively new to our food system, and they've only been around since the introduction of Crisco in 1911. Prior to that, we didn't see much of the diseases that these oils have been linked to. And it's not just the correlation - if you look at the numbers, you'll see that the use of these oils has paralleled the rise in obesity, type two diabetes, and heart disease, while traditional fats like tallow, butter, lard, olive oil, and coconut oil have not shown the same correlation.

Hit play to hear this episode of the Healthy AF podcast is all about educating you about the dangers of seed oils and how to make informed choices about what you eat. The information about the correlation between these oils and the rise in diseases is backed up by peer-reviewed studies, and it's something that we all need to be aware of. By choosing to avoid these hateful oils and opting for traditional fats, we can help keep our bodies healthy and strong.
