What do experts say about health hazards & benefits of seed oils?
Seed oils, such as those extracted from sunflowers, canola, and flaxseeds, have gained popularity in recent years due to their supposed health benefits. However, critics have raised concerns about the potential health hazards associated with these oils. One of the main concerns is the presence of hexane, a chemical considered hazardous in gaseous form. But what do experts say about the health hazards and benefits of seed oils?
Toxic byproduct of hexane: A myth or reality?
Proponents of seed oils have long been criticized for their alleged connection to hexane, a chemical solvent used in the oil extraction process. Critics claim that hexane residues can be found in seed oils, posing a significant health risk to consumers. However, experts argue that the presence of hexane residues is not a cause for concern.
According to Eric Decker, a Massachusetts University Food Science professor, the residue of hexane in seed oil is not dangerous. “The amount of hexane in seed oil is incredibly small,” Decker said in an interview. “You would need to consume an enormous amount of seed oil to reach a level of hexane that would be considered harmful.”
Inflammation markers: The verdict
Another concern surrounding seed oils is their potential to increase inflammation markers in the body. Inflammation is a natural response to injury or infection, but chronic inflammation has been linked to various diseases, including heart disease, cancer, and Alzheimer’s. Critics of seed oils claim that they can exacerbate inflammation, leading to a range of health problems.
However, experts from Ohio University’s Food Science department have debunked this myth. According to Dr. Kathryn Dewey, a professor at Ohio University, “Seed oils don’t increase acute or chronic inflammation markers.” In fact, some seed oils, such as those rich in omega-3 fatty acids, may even have anti-inflammatory properties.
Health benefits of seed oils
Despite the controversy surrounding seed oils, experts agree that they can provide numerous health benefits when consumed as part of a balanced diet. Here are some of the key benefits:
- Heart health: Seed oils are rich in unsaturated fats, which can help lower LDL (bad) cholesterol levels and reduce the risk of heart disease.
- Brain function: Omega-3 fatty acids found in seed oils, such as flaxseed oil, have been shown to improve brain function and reduce the risk of depression.
- Anti-inflammatory effects: As mentioned earlier, some seed oils may have anti-inflammatory properties, which can help reduce the risk of chronic diseases.
- Skin health: Seed oils can be used topically to moisturize and nourish the skin, reducing the appearance of fine lines and wrinkles.
Conclusion
While critics have raised concerns about the potential health hazards associated with seed oils, experts argue that the benefits of these oils far outweigh the risks. The presence of hexane residues is minimal and not considered harmful, and seed oils do not increase inflammation markers. In fact, some seed oils may even have anti-inflammatory properties.
When consumed as part of a balanced diet, seed oils can provide a range of health benefits, from improving heart health to reducing inflammation. So, the next time you’re cooking up a storm in the kitchen, consider reaching for a seed oil to add some extra nutrition to your meal.
