Vegetable oils help lower blood lipids: A guide to scientific selection and consumption.
Consuming more vegetable oils is recommended: Domestic and international studies have proven that rice bran oil can lower serum cholesterol levels. According to reports, young women who consume rice bran oil experience a cholesterol reduction of approximately 17%; when combined with safflower oil, the effect is even better, lowering serum cholesterol by 19%–21%. Therefore, individuals with hyperlipidemia should consume rice bran oil regularly.
Peanut oil, rapeseed oil, soybean oil, sunflower seed oil, sesame oil (or fragrant oil), salad oil, and cottonseed oil are commonly used vegetable oils, rich in unsaturated fatty acids, which are composed of monounsaturated and polyunsaturated fatty acids. Research and experiments have demonstrated that monounsaturated fatty acids are very effective in lowering low-density lipoprotein cholesterol (LDL-C) and total cholesterol (TC) levels, but have a weaker effect on increasing high-density lipoprotein cholesterol (HDL-C) levels compared to polyunsaturated fatty acids. Polyunsaturated fatty acids are composed of linoleic acid and linolenic acid. Linoleic acid is an essential fatty acid for the human body. This fatty acid cannot be synthesized by the body and must be obtained from food. Vegetable oils contain a large amount of linoleic acid, with sunflower seed oil having the highest content (up to 66%), soybean oil (51%), cottonseed oil (48%), and sesame oil (41%). Research and observation have long proven that it plays an important role in lowering serum total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TG). Linolenic acid not only significantly lowers serum total cholesterol (TC) and triglyceride (TG) levels but also raises high-density lipoprotein cholesterol (HDL-C) levels. However, vegetable oils contain relatively little linolenic acid; soybean oil contains only 6.5%. Therefore, for individuals with hyperlipidemia, the latter should be chosen over animal oils; eat more vegetable oils and less animal oils. This not only lowers blood lipid levels but also effectively prevents atherosclerosis and coronary heart disease. It should also be noted that vegetable oils are high-energy foods; to prevent obesity, they should not be consumed excessively.
Improper vitamin supplementation and frequent consumption of sugary drinks: A double health risk warning
This article reveals that blindly supplementing with vitamins (such as calcium and vitamin D) is not only ineffective but may also increase the risk of death and poisoning.

Dinner time affects heart health: Eating before 6 PM helps prevent high blood pressure and diabetes.
A study by the American Heart Association revealed that eating dinner too late (after 6 PM) and with excessive calories significantly increases the risk of high blood pressure and prediabetes, thus threatening heart health. It is recommended to have dinner before 6 PM and control calorie intake; this is an important lifestyle adjustment for protecting the heart and preventing cardiovascular disease.
