“Eat less lard. If you eat too much, you will get heart disease and cancer!”

Today, Xiao Liu began to persuade Grandpa Liu to eat less pigs It’s oily. Grandpa Liu is 72 years old this year. He has been eating lard for decades. In recent years, his grandson who went to college said that lard was unhealthy and told him to eat less.

“You young people don’t know that lard is a good thing with high nutritional value.” Grandpa Liu retorted with his eyes wide open.

“Experts have all said that lard is too high in saturated fat, which is not good for nutrition!” Xiao Liu Zhen said eloquently.

“So many people used to eat lard, but now I’m not living well!”

“Now What is the age, in the past it was the poor who had to eat lard.”

… No one, there was a quarrel.

Lard is a highly controversial food, which has always been in the nutritious and garbage Repeatedly jumping between foods, is it nutritious, will it cause cancer and heart disease?

I. Will eating too much lard cause cancer?

In recent years, there have been many doubts about lard. The reason why lard is considered unhealthy is mainly because it is rich in saturated fatty acids< /strong>. Excessive intake of saturated fatty acids is associated with an increased risk of atherosclerosis, coronary heart disease, diabetes, rectal cancer, and breast cancer. Therefore, many people think that for the sake of health, they can no longer eat lard.

Most animal fats contain40~60% saturated fatty acids, 30~50% monounsaturated fatty acids plus a small amount of polyunsaturated fatty acids. Vegetable oils contain 10-20% saturated fatty acids plus 80-90% unsaturated fatty acids.

In fact, lard is not as unhealthy as you might think! Lard health is not healthy, mainly depends on the amount of intake. Although unsaturated fatty acids are healthier than saturated fatty acids, they should not be consumed in excess. A large intake of unsaturated fatty acids will also form fat in the body, leading to an increased risk of various diseases.

Dietary Guidelines for Chinese Residents 2016 states that adults consume cooking oil daily Should be limited to 25~30g.

Potential cancer risk of vegetable oil may be greater than lard in some respects !

Beijing Satellite TV has conducted experiments on vegetable oil and animal oil, and found that the smoke points of vegetable oil and lard are 155.5 degrees in the experiment , 197 degrees. The lower the smoke point temperature, the easier the fat in the oil is decomposed, and the easier it is to be oxidized during the cooking process, resulting in carcinogens. When frying and cooking at high temperatures, it may be safer to use lard than vegetable oil.

Second, will eating lard often cause heart disease?

At present, whether saturated fatty acids will increase cardiovascular disease is still controversial, but some studies have pointed out that saturated fatty acids are not related to cardiovascular disease. A 2020 joint analysis of studies by the American Heart Association found no association between saturated fatty acid intake and risk of heart disease.

Hu Xinzhi, Department of Health Management, The Third Xiangya Hospital, Central South University pointed out that low-density lipoprotein cholesterol can It is divided into two types: A and B. Type A is characterized by large volume and fluffy. This kind of low-density lipoprotein cholesterol is difficult to penetrate into the blood vessel wall and will not significantly increase the risk of cardiovascular disease; while type B is bulky. Small, dense, B-LDL cholesterol enters blood vessels more easily, leading to an increased risk of cardiovascular disease.

After natural saturated fatty acids such as lard enter the body,It will lead to an increase in the content of low-density lipoprotein cholesterol type A in the body, rather than the easily oxidized type B, so the occurrence of cardiovascular disease and lard not significantly related.

So lard is a mediocre food. If it is some healthy people, proper consumption of lard will not bring too much risk to health. If you already have cardiovascular disease, you still need to control the intake of fat in your daily diet, and try to eat less lard.

Third, people often eat lard in the past, why are there so few people with heart disease and cancer? More now?

In times of economic difficulties in the past, lard was indeed a precious edible oil and nutrients. Now that people’s lives have improved, many people feel that lard is unhealthy and eat less lard , Why do more people get heart disease and cancer? 1. In the past, the calorie consumption was large, and the total fat intake was not high

In the older generation In that generation, lard was even considered one of the best foods due to material scarcity. Most of the people at that time required heavy physical labor, and the calorie consumption was very large. However, the total fat intake of the body is very low, in this case the risk of cardiovascular disease is low.

2. Now the diet structure has changed, and many people are overnourished

Modern people Most people do not have insufficient nutritional intake, and most people eat well, with sufficient or even excessive calorie intake. In this case, consuming lard may lead to excessive nutritional content in the body. In addition, most modern people do not need to do heavy physical labor, and the body consumes too few calories and consumes too much calories, which easily increases the risk of various diseases, including heart disease and cancer.

< p>The occurrence of heart disease and cancer is often the result of a combination of factors. We cannot simply blame it on a certain food. There is no good or bad food. It is good food, but if it is used incorrectly, it will bring health risks. In life, we should learn how to eat healthy, instead of directly pulling some foods into the “blacklist” and never hiring. #HealthStar Plan# #Health2022#
