In our daily lives, fats and fats are indispensable and important ingredients for our cooking. However, not all oils and fats are good for our health. In recent years, there has been a lot of controversy about whether soybean oil is healthy, but in reality, some oils and fats can be far more harmful than soybean oil. The doctor admits that there are three kinds of oils that should arouse our vigilance and try to avoid consumption. This article will help you make a more informed choice by dissecting the unhealthy factors of these three types of fats.1. Trans fatty acidsTrans fatty acids, also known as "devil fats," are synthetic fats. It is mainly found in partially hydrogenated vegetable oils, such as margarine, margarine, etc. Trans fatty acids can increase the crispy taste of food and extend the shelf life during food processing, so they are widely used in baked and fried foods.
However, trans fatty acids are extremely harmful. Studies have shown that trans fatty acids increase the risk of cardiovascular diseases, such as coronary heart disease, stroke, etc. In addition, it may affect the growth and development of infants and young children, causing damage to the nervous system and immune system. Therefore, doctors strongly recommend avoiding fats and fats that contain trans fatty acids.
Anatomy of knowledge points:
Trans fatty acids**: Partially hydrogenated vegetable oils are the main trans fatty acids**. During the hydrogenation of vegetable oil, some unsaturated fatty acids undergo a configuration transformation to form trans fatty acids.
Dangers of trans fatty acids: Trans fatty acids increase the level of LDL cholesterol (bad cholesterol) and decrease the level of HDL cholesterol (good cholesterol), which increases the risk of cardiovascular disease. In addition, it may affect the growth and development of infants and young children and the normal functioning of the nervous system.
How to avoid trans fatty acids: When buying food, pay attention to the ingredient list on the food label and avoid buying foods that contain ingredients such as "partially hydrogenated vegetable oil", "margarine", "margarine", etc. At the same time, reducing the consumption of fried and baked foods can also reduce the intake of trans fatty acids.
2. Palm oil
Palm oil is an oil extracted from palm fruit and is widely used in food processing, cooking, and cosmetics. While palm oil has some nutritional value in some ways, excessive intake of palm oil can have negative effects on human health.
Palm oil is high in saturated fatty acids, especially palmitic acid. Excessive intake of saturated fatty acids increases the risk of cardiovascular diseases, such as high blood pressure, coronary heart disease, etc. In addition, palm oil may affect the body's absorption and utilization of fat-soluble vitamins.
Anatomy of knowledge points:
Palm oil** and applications: Palm oil is an oil extracted from the fruit of palm trees, which is widely used in food processing, cooking, cosmetics and other fields. Because of its good stability and relatively low **, it is favored by many food manufacturers.
Harm of palm oil: Palm oil has a high content of saturated fatty acids, especially palmitic acid. Excessive intake of these saturated fatty acids increases the risk of cardiovascular disease. In addition, long-term high intake of palm oil may also affect the body's absorption and utilization of fat-soluble vitamins, leading to malnutrition.
How to reduce palm oil intake: When buying food, pay attention to the ingredient list on the food label and avoid buying foods that contain a lot of palm oil. At the same time, reducing the consumption of fried and puffed foods can also reduce the intake of palm oil. In daily cooking, you can choose to replace some palm oil with other vegetable oils to reduce your intake of saturated fatty acids.
3. Gutter oil
Gutter oil is a kind of inferior oil that is illegally produced and sold, mainly in kitchen waste oil, swill oil, etc. Gutter oil is simply processed and then reintroduced to the market for use in cooking and food processing. Due to the complexity of gutter oil and the unhygienic processing process, it may contain a large number of harmful substances and bacteria.
Long-term consumption of gutter oil can cause serious harm to human health. The harmful substances in gutter oil may cause damage to organs such as liver and kidneys, and even cause serious diseases such as cancer. In addition, the bacteria in gutter oil can also cause acute health problems such as food poisoning. Therefore, doctors strongly recommend avoiding the consumption of gutter oil.
Anatomy of knowledge points:
Gutter oil: Gutter oil is mainly used in kitchen waste oil, swill oil, etc. These waste oils and fats are collected by criminals and then re-introduced to the market after simple processing.
Hazards of gutter oil: Due to the complexity of gutter oil and the unhygienic processing process, it may contain a large number of harmful substances and bacteria. Long-term consumption of gutter oil can cause serious harm to human health, such as liver and kidney damage, cancer, etc. In addition, the bacteria in gutter oil can also cause acute health problems such as food poisoning.
How to avoid gutter oil: When eating out, choose a formal and hygienic restaurant; When buying food, pay attention to check the information such as food labels and production dates; Try to avoid buying unidentified bulk fats and fried foods. At the same time, strengthening food safety awareness and understanding food safety knowledge is also an effective way to avoid the hazards of gutter oil.
In conclusion, the three types of fats and fats that doctors warn us to try to avoid are trans fatty acids, palm oil, and gutter oil. These oils and fats can pose serious health risks due to factors such as **, processing methods or hygienic conditions. To protect our health, we should choose healthier oils**, such as vegetable oils such as olive oil and canola oil, and consume them in moderation. At the same time, strengthening food safety awareness and understanding food safety knowledge is also an important measure for us to protect the health of ourselves and our families.
