In modern society, people are paying more and more attention to healthy eating, and they are becoming more cautious about the choice of fats and fats. Lard, as a traditional edible oil, once occupied an important position in China's food culture. However, with the popularization of health concepts, the health effects of lard have gradually become the focus of attention. This article will reveal the true face of lard to help you make healthier eating choices.
1. The composition and nutritional value of lard.
Lard, as the name suggests, is an edible oil made from the fat tissue of pigs that is refined by heating. Its main components are saturated fatty acids, which account for a large proportion of total fatty acids. In addition, lard also contains a certain amount of monounsaturated fatty acids and polyunsaturated fatty acids, as well as a small amount of vitamin E, cholesterol and other nutrients.
From the perspective of nutritional value, lard, as an oil, can provide energy for the human body, help the absorption of fat-soluble vitamins, and participate in the construction of cell membranes. However, the high saturated fatty acid content in lard makes it a risk factor for cardiovascular disease. Therefore, when consuming lard, we need to control our intake reasonably to maintain a healthy diet.
2. Health effects of lard.
1.Cardiovascular disease.
The high saturated fatty acid content in lard makes it a risk factor for cardiovascular disease. Excessive intake of saturated fatty acids can lead to elevated levels of low-density lipoprotein cholesterol (LDL-C) in the blood, which in turn increases the risk of arteriosclerosis and cardiovascular disease. Therefore, long-term consumption of lard in large quantities may adversely affect cardiovascular health.
2.Obesity problems.
Lard is a high-energy-density food, and excessive intake can easily lead to excess energy intake, which in turn leads to obesity. Obesity is a risk factor for a variety of chronic diseases, including cardiovascular disease, diabetes, hypertension, etc. Therefore, controlling lard intake is of great significance for the prevention of obesity and chronic diseases.
3.Harmful substances produced during cooking.
During high-temperature cooking, lard may produce some harmful substances such as trans fatty acids and acrylamide. These harmful substances pose a potential threat to human health, such as increasing the risk of cardiovascular disease, affecting growth and development, etc. Therefore, during the cooking process, heating lard at high temperatures for a long time should be avoided as much as possible to reduce the production of harmful substances.
3. Healthier eating choices.
1.Diversification of oils and fats.
In order to maintain a healthy diet, we should minimize our intake of lard and use other vegetable and animal oils instead. For example, vegetable oils such as olive oil, camellia oil, and flaxseed oil are rich in monounsaturated and polyunsaturated fatty acids, which are beneficial for cardiovascular health. At the same time, proper intake of animal oil, such as fish oil, chicken fat, etc., can supplement the essential fatty acids required by the body.
2.Consume in moderation.
Oils and fats are one of the nutrients the body needs, and it is not wise to cut them out completely. Moderate intake of fats, especially those rich in unsaturated fatty acids, can help maintain physical performance. It is recommended that the total amount of fat consumed per day should be controlled at about 25-30 grams, of which the intake of lard should be controlled within 5-10 grams.
3.Increase dietary fiber.
Dietary fiber helps reduce the absorption of cholesterol, which reduces the risk of cardiovascular disease. Therefore, we should add foods rich in dietary fiber, such as vegetables, fruits, whole grains, etc., to our diet. At the same time, eating more low-fat and high-protein foods such as fish and lean meat can help reduce the intake of saturated fatty acids.
4.Rational cooking methods.
During the cooking process, try to avoid heating the grease at high temperatures for a long time to reduce the production of harmful substances. Methods such as low-temperature cooking, steaming, and boiling can be used to maintain the nutrient content of food and reduce food safety risks.
Summary: As a traditional edible oil, lard once occupied an important position in China's food culture. However, with the spread of health perceptions, we need to have a deeper understanding of what lard really looks like in order to make healthier dietary choices. By controlling the intake of lard reasonably, diversifying the intake of fats and fats, increasing the intake of dietary fiber, and adopting reasonable cooking methods, we can enjoy delicious food while maintaining good health.
