What Do Experts Say About Health Hazards & Benefits of Seed Oils?
Seed oils have been a topic of debate in the health and wellness community, with some experts claiming they pose health hazards, while others argue they are a healthy choice. Among the concerns are the unsaturated fatty acids they contain, as well as the potential presence of toxic byproducts like hexane. But what do the experts really say about the health benefits and risks of seed oils? Let’s dive into the science.
Critics of seed oils claim that the unsaturated fatty acids they contain can lead to inflammation in the body, which is a known precursor to chronic diseases like heart disease, diabetes, and cancer. They also point to the potential presence of hexane, a chemical considered hazardous in gaseous form, which is used in the extraction process of seed oils. However, this is where the experts come in to set the record straight.
Massachusetts University Food Science Professor Eric Decker, an expert in the field of seed oils, says that the residue of hexane in seed oil is not a cause for concern. “The amounts of hexane that are left in seed oils are extremely low, and it’s not like you’re going to get a huge dose of hexane by consuming these oils,” said Decker in an interview with a leading health publication.
But what about the inflammation concerns? According to Ohio University Food Science professor, seed oils do not increase acute or chronic inflammation markers. This is a crucial finding, as inflammation is a major risk factor for many chronic diseases. In fact, research has consistently shown that whole grains, nuts, and seeds, which are rich in healthy fats, can actually help reduce inflammation in the body.
Another expert, Dr. Dariush Mozaffarian, a cardiologist and epidemiologist at Tufts University, has conducted extensive research on the health effects of seed oils. He has found that seed oils, particularly those high in omega-3 fatty acids, can help reduce the risk of heart disease by lowering triglycerides and blood pressure.
So, what are the benefits of seed oils? For starters, they are rich in healthy fats, which can help reduce inflammation and improve heart health. They are also high in antioxidants, which can help protect against cell damage and reduce the risk of chronic diseases. Additionally, seed oils are a good source of essential fatty acids, which are important for brain function and development.
But which seed oils are considered healthy, and which should be avoided? According to the experts, some of the healthiest seed oils include:
- Flaxseed oil: Rich in omega-3 fatty acids, flaxseed oil has been shown to reduce inflammation and improve heart health.
- Chia seed oil: High in omega-3 fatty acids and antioxidants, chia seed oil is a great choice for heart health and anti-inflammatory support.
- Hemp seed oil: Rich in essential fatty acids and antioxidants, hemp seed oil is a great choice for brain function and overall health.
- Walnut oil: High in omega-3 fatty acids and antioxidants, walnut oil is a great choice for heart health and anti-inflammatory support.
On the other hand, some seed oils should be avoided, including:
- Canola oil: High in omega-6 fatty acids, which can promote inflammation, and often contains genetically modified organisms (GMOs).
- Soybean oil: High in omega-6 fatty acids and often contaminated with pesticides and heavy metals.
- Cottonseed oil: High in omega-6 fatty acids and often contains contaminants like pesticides and heavy metals.
In conclusion, while some critics claim that seed oils are a health hazard, the experts say otherwise. With their rich content of healthy fats, antioxidants, and essential fatty acids, seed oils can be a valuable addition to a healthy diet. Just be sure to choose the right types of seed oils, and avoid those that are high in omega-6 fatty acids or contaminants.
