Understanding the fundamental characteristics of various oils enables better selection. Additionally, what should be considered when using oils? Below, our food and beverage website explores the best cooking oils for daily use.
I. Best Everyday Cooking Oils
1. Corn Oil
Extracted from corn germ, this high-quality vegetable oil boasts over 97% human absorption rate. Rich in natural antioxidant vitamin E, it helps lower cholesterol levels, strengthens muscle and cardiovascular function, and enhances immune resistance.Corn oil has excellent thermal stability, making it suitable for stir-frying and deep-frying. 2. Lard Contains high levels of saturated fatty acids. Excessive consumption may lead to hyperlipidemia, fatty liver, atherosclerosis, and obesity. However, lard remains essential as its cholesterol serves as a raw material for the body to produce steroid hormones, adrenal cortex hormones, sex hormones, and synthesize vitamin D.The alpha-lipoprotein in lard can extend lifespan, a property lacking in vegetable oils. 3. Peanut Oil Rich in oleic acid, lecithin, vitamins A, D, E, K, and bioactive natural polyphenols, it reduces platelet aggregation, lowers total cholesterol and LDL levels, and prevents arteriosclerosis and cardiovascular diseases.Peanuts are prone to contamination by Aspergillus flavus, whose toxins exhibit potent carcinogenicity. Therefore, crude peanut oil is unsafe. When purchasing, always select premium branded peanut oil from reputable stores or supermarkets. Rich in monounsaturated fatty acids and vitamin E, peanut oil boasts better heat stability than salad oil, making it an excellent high-temperature cooking oil.
4. Olive Oil
The most expensive option. It contains the highest levels of monounsaturated fatty acids among all edible oils. It effectively lowers LDL cholesterol while raising HDL cholesterol, thereby helping prevent cardiovascular diseases and reducing the risk of cholecystitis and gallstones.Olive oil also contains vitamins A, D, E, K, and carotene, which help improve digestive function, enhance calcium deposition in bones, and delay brain atrophy. Among all cooking oils, olive oil commands the highest price because the olive oil sold in China is primarily imported.The advantage of olive oil lies in its richness in monounsaturated fatty acids—oleic acid. Research confirms that polyunsaturated fatty acids like linoleic and linolenic acids can cause oxidative damage in the body, and excessive consumption is equally detrimental to health; saturated fatty acids tend to raise blood lipids. Oleic acid, as a monounsaturated fatty acid, avoids both these adverse effects and possesses excellent heat resistance.When purchasing olive oil, opt for extra virgin for the highest quality. Olive oil possesses a distinctive, delicate aroma suitable for stir-frying, though its maximum safe cooking temperature should not exceed 190°C (370°F). It also enhances the flavor of cold dishes when used as a dressing.Its fatty acid composition is favorable, rich in linoleic acid, which significantly lowers serum cholesterol levels and helps prevent cardiovascular diseases. Soybeans also contain substantial amounts of vitamins E and D, along with abundant lecithin, all highly beneficial for human health. Additionally, soybean oil boasts a high human digestibility rate of 98% and is inexpensive, offering excellent overall value. However, soybean salad oil cannot withstand high temperatures, making it unsuitable for high-heat stir-frying or deep-frying.
6. Sunflower Oil
Sunflower oil is rich in essential fatty acids and unsaturated fats. Its high linoleic acid content helps regulate metabolism, stabilize blood pressure, significantly lower cholesterol, prevent vascular hardening, and guard against coronary heart disease. It also contains abundant active vitamin E, which activates capillaries and promotes blood circulation.Refined sunflower oil is suitable for simmering and stir-frying at moderate temperatures but is not recommended for deep-frying.
7. Blended Oil
Blended oil is a cooking oil made by combining two or more refined oils in specific proportions. It blends nutrition with flavor, offering consumers enhanced taste and richer nutritional value. It is suitable for everyday stir-frying.
