What do experts say about health hazards & benefits of seed oils?
Seed oils, which are rich in unsaturated fatty acids, have been a topic of debate among health enthusiasts and nutritionists. While some critics claim that these oils contain toxic byproducts of hexane, a chemical considered hazardous in its gaseous form, other experts argue that the residue of hexane in seed oils is not dangerous. In this blog post, we will delve into the world of seed oils, exploring both the potential health hazards and benefits, and what experts have to say about them.
What are seed oils?
Seed oils are extracted from various plant seeds, such as sunflower, canola, and flaxseed. These oils are rich in unsaturated fatty acids, which are considered healthy fats. Unsaturated fats help lower cholesterol levels, reduce blood pressure, and improve heart health.
The critics: hexane and its byproducts
One of the main concerns about seed oils is the use of hexane, a chemical solvent, in the extraction process. Hexane is considered hazardous in its gaseous form, and some critics argue that it can leave behind toxic byproducts in the final product. These byproducts, they claim, can cause harm to our health.
However, experts argue that the residue of hexane in seed oils is not a cause for concern. According to Massachusetts University Food Science Professor Eric Decker, “The amounts of hexane residue in seed oils are extremely low and would not be expected to cause harm to human health.”
The benefits of seed oils
Despite the concerns about hexane, seed oils have been shown to have numerous health benefits. These benefits include:
- Heart health: The unsaturated fats in seed oils help lower cholesterol levels, reduce blood pressure, and improve blood lipid profiles, all of which can reduce the risk of heart disease.
- Anti-inflammatory properties: Some seed oils, such as flaxseed oil, contain omega-3 fatty acids, which have been shown to have anti-inflammatory properties, reducing the risk of chronic diseases such as arthritis and cardiovascular disease.
- Brain health: The omega-3 fatty acids in seed oils have also been shown to promote brain health, reducing the risk of depression, anxiety, and other mental health disorders.
- Skin health: Seed oils are often used in skincare products due to their moisturizing and anti-inflammatory properties, which can help reduce the signs of aging and improve skin health.
The science behind seed oils
To better understand the health effects of seed oils, we need to look at the science behind them. According to an Ohio University Food Science professor, “Seed oils don’t increase acute or chronic inflammation markers.” This means that seed oils do not cause inflammation in the body, which is a major risk factor for chronic diseases such as heart disease, diabetes, and cancer.
In fact, a study published in the Journal of Agricultural and Food Chemistry found that flaxseed oil, a type of seed oil, reduced inflammation in rats with colitis, a condition characterized by chronic inflammation in the colon.
Conclusion
While critics of seed oils claim that they contain toxic byproducts of hexane, experts argue that the residue of hexane in seed oils is not a cause for concern. Seed oils have been shown to have numerous health benefits, including heart health, anti-inflammatory properties, brain health, and skin health. The science behind seed oils suggests that they do not increase inflammation markers, which is a major risk factor for chronic diseases.
In conclusion, seed oils are a healthy and nutritious addition to a balanced diet. While it is important to be aware of the potential concerns about hexane, the evidence suggests that the benefits of seed oils far outweigh the risks. So, go ahead and include seed oils in your diet – your body will thank you!
