Imagine a simple ingredient that not only enriches your table, but also protects your health before you know it. This is pork liver, a health treasure that we are familiar with but may not have a deep understanding of.
Let me take you back to last winter, when Mr. Li, a 70-year-old retired teacher, suffered from a long period of high blood pressure and blood sugar problems, and his quality of life was greatly reduced. However, on the advice of his doctor, he began to selectively incorporate pork liver into his diet plan. After a few months, Mr. Lee's blood pressure and blood sugar levels improved significantly, and he felt more energetic and his quality of life improved significantly. The secret behind this is the seemingly ordinary pork liver.
Analysis of the nutritional composition of pork liver: it is not only delicious, but also a treasure trove of health
Pork liver, as a common ingredient in daily diet, its nutritional value and health benefits should not be underestimated. This part will deeply explore the rich nutrients in pig liver and its important role in human health, and provide practical knowledge for middle-aged and elderly people who love health and wellness.
Rich source of iron
Pork liver is an excellent source of iron, especially for the prevention and improvement of anemia. Iron is a key component of red blood cell formation and is essential for oxygen transport and energy metabolism.
Compared to plant-based iron sources, the iron in pig liver is more easily absorbed by the body.
A natural reservoir of vitamin A
Pork liver is rich in vitamin A, which has a positive effect on the maintenance of vision health, skin maintenance and immune system function.
It also helps maintain mucosal tissue health and strengthens the body's resistance to bacteria and viruses.
Excellent source of protein
Protein is an important component in building and repairing body tissues. The high-quality protein in pork liver aids in muscle maintenance, tissue repair, and the production of enzymes and hormones.
For middle-aged and elderly people, it is especially important to consume high-quality protein in moderation to maintain physical function and health.
A treasure trove of trace elements
Pork liver also contains a variety of trace elements, such as copper, zinc, selenium, etc., which are essential for maintaining a variety of physiological functions in the human body.
These trace elements have a positive effect on immune system function, wound healing, and thyroid function, among other things.
Cholesterol in pig liver
Despite its high nutritional value, pork liver also contains high cholesterol. Therefore, the health status of the individual should be taken into account when consuming, and people with hypercholesterolemia or heart disease should consume with caution.
Pork liver: a natural treasure trove for lowering blood pressure, blood sugar and blood lipids
The relationship between pig liver and blood pressure, blood sugar and blood lipids
Pork liver, as a common ingredient, is not only rich in nutrients, but may also play an important role in regulating blood pressure, blood sugar, and blood lipids. First of all, pork liver is rich in iron and B vitamins, which are essential for maintaining normal blood pressure levels. Iron contributes to the formation of red blood cells, which improves blood circulation and oxygen delivery, which in turn may be beneficial in lowering blood pressure. B vitamins, especially vitamin B12 and folic acid, are essential for cardiovascular health and help reduce levels of homocysteine, an amino acid linked to the risk of high blood pressure and heart disease.
In addition, minerals and proteins in pork liver may help with blood sugar control. These nutrients help regulate the function of insulin, a key hormone that regulates blood sugar levels. However, the current research on the direct effect of pig liver on blood sugar control is insufficient, and more scientific evidence is needed.
Regarding blood lipids, some components in pig liver, such as phospholipids and essential fatty acids, may be beneficial in maintaining normal blood lipid levels. These nutrients are essential for the integrity and function of cell membranes and may also help regulate lipid levels in the blood.
Recommendations for rational consumption of pork liver
Moderate amount is king: It is recommended to consume pork liver 1 to 2 times a week, no more than 100 grams each time. Excessive consumption may lead to problems such as excess vitamin A.
Cooking methods are diverse: pork liver can be made into stir-fries, stews or soups. Avoid excessive frying to avoid increasing unnecessary fat intake.
Pair with vegetables: Eat with vegetables rich in vitamin C such as tomatoes and green peppers to help improve the efficiency of iron absorption.
Pay attention to food safety: Choose fresh pork liver and cook it thoroughly until cooked through to avoid food infectious diseases.
