What do experts say about health hazards & benefits of seed oils?
Seed oils, which are extracted from the seeds of plants like sunflowers, canola, and flax, have been a topic of controversy in recent times. Critics of seed oils claim that they contain toxic byproducts of hexane, a chemical considered hazardous in gaseous form. However, experts in the field of food science have debunked these myths and revealed the science behind the benefits and potential hazards of seed oils.
One of the main concerns about seed oils is the presence of hexane, a chemical solvent used in the extraction process. Critics argue that hexane residues in seed oil can be harmful to human health. However, Massachusetts University Food Science Professor Eric Decker disputes this claim, stating that the amount of hexane residue in seed oil is negligible and poses no significant health risk.
Decker’s statement is backed by scientific research. A study published in the Journal of Agricultural and Food Chemistry found that the levels of hexane residue in commercial seed oils are well within the acceptable limits set by regulatory agencies. The study concluded that the risk of hexane toxicity from consuming seed oils is extremely low.
Another concern about seed oils is their potential to increase inflammation in the body. Some critics claim that the high levels of unsaturated fatty acids in seed oils can lead to chronic inflammation, which is linked to various diseases such as heart disease, cancer, and Alzheimer’s. However, Ohio University Food Science Professor Dr. Kathryn Dewey disagrees with this notion.
According to Dr. Dewey, seed oils do not increase acute or chronic inflammation markers. In fact, some seed oils, such as flaxseed oil, contain anti-inflammatory compounds that may even help reduce inflammation in the body.
So, what do the experts say about the health benefits of seed oils? According to Dr. Decker, seed oils are a rich source of essential fatty acids, vitamins, and antioxidants, which can provide numerous health benefits. For example, omega-3 fatty acids found in flaxseed oil have been shown to reduce triglycerides, improve blood lipids, and lower blood pressure.
In addition to their potential health benefits, seed oils are also a popular choice for cooking and baking due to their mild flavor and high smoke point. Canola oil, for example, is a popular choice for frying and sautéing due to its neutral flavor and high smoke point of 468°F (242°C).
Despite their benefits, seed oils are not without their limitations. Some seed oils, such as canola oil, are often genetically modified, which can be a concern for those who prefer non-GMO products. Additionally, some seed oils may contain pesticides and other contaminants, which can be a risk for those who consume them in large quantities.
In conclusion, while seed oils may have some potential health hazards, the experts agree that the benefits of seed oils far outweigh the risks. With their rich source of essential fatty acids, vitamins, and antioxidants, seed oils can provide numerous health benefits and can be a healthy addition to a balanced diet. However, it is important to choose high-quality seed oils that are free from contaminants and pesticides, and to consume them in moderation as part of a balanced diet.
