There are many authoritative scientific experiments proving that flaxseed oil is a natural vegetable oil with multiple health benefits. It is known as the "smart oil" for brain health and intelligence, the "fat-scraping oil" for cleansing blood vessels and reducing fat and weight. It also helps regulate "three highs" (high blood pressure, high blood sugar, and high cholesterol), prevent diabetes, relieve allergic dermatitis and eczema, and has anti-cancer effects.
Flaxseed oil is quite "delicate" because it contains alpha-linolenic acid, which is not heat-resistant and is easily oxidized at room temperature. Therefore, it has a low smoke point. High-temperature cooking can produce many harmful substances and also diminish its health benefits. Thus, flaxseed oil is suitable for cold dishes, soups, or mixed with yogurt.
There are two types of flaxseed oil: cold-pressed and hot-pressed. Cold-pressed oil is not subjected to high temperatures or excessive processing, retaining many beneficial nutrients for the human body, including alpha-linolenic acid and Vitamin E. It is typically light yellow in color with a light, pleasant aroma. Hot-pressed flaxseed oil undergoes high-temperature heating, is generally dark brown in color, and has a rich, roasted aroma. Many nutrients are lost during the heating process. Therefore, when purchasing flaxseed oil, it is recommended to choose cold-pressed flaxseed oil as the first choice. Relatively speaking, cold-pressed flaxseed oil is more nutritious and has greater health benefits, making it safer and healthier to consume.
Due to its sensitivity to high temperatures and susceptibility to oxidation, it is recommended to store flaxseed oil in a refrigerator. After use, ensure the cap is tightened tightly. Once opened, try to use the flaxseed oil within a short period of time; it should not be kept for too long.
