Mr. Zhang is 65 years old this year. He has always enjoyed eating meat, especially fatty meat. Every time he gathers with his old friends, he can’t do without a few pieces of delicious braised pork. However, after a recent physical examination, the doctor told him that his blood pressure was slightly high and advised him to control his diet. Mr. Zhang was puzzled: Does fatty meat really raise blood pressure? Can he still enjoy his favorite foods?
With doubts, Mr. Zhang attended a health lecture in the community. The keynote speaker, Dr. Wang, is a senior cardiovascular expert with many years of clinical experience. Dr. Wang noticed Mr. Zhang’s doubts and decided to use his example to start today’s lecture. He straightforwardly said, “Today, let’s talk about the relationship between fatty meat and blood pressure, and see if hypertensive patients can really eat fatty meat.”
The Relationship Between Fatty Meat and Blood Pressure: The Truth Revealed
The main component of fatty meat is fat, especially saturated fatty acids. Saturated fatty acids are solid at room temperature, and excessive intake can lead to high cholesterol in the blood, which in turn causes atherosclerosis. Atherosclerosis can lead to decreased blood vessel elasticity, obstruction of blood flow, and ultimately result in high blood pressure.
Saturated Fatty Acids and Atherosclerosis
Saturated fatty acids are mainly found in animal fats, such as the fatty parts of pork, beef, and lamb. When too much saturated fatty acids are consumed, the level of low-density lipoprotein cholesterol (LDL-C) in the blood increases. This “bad” cholesterol tends to deposit on the arterial walls, forming atherosclerotic plaques. These plaques narrow and stiffen the arteries, increasing resistance to blood flow and raising blood pressure.
High-Fat Diet and Blood Lipid Levels
A high-fat diet not only increases cholesterol levels in the body but also leads to weight gain. Obesity is an important risk factor for high blood pressure. Excessive body fat increases the burden on the heart, causing it to pump blood more forcefully, thereby raising blood pressure. In addition, a high-fat diet also affects endothelial function, increases inflammation reactions, all of which are closely related to the occurrence and development of high blood pressure.
Effects of Blood Lipid Levels on Blood Pressure
Blood lipid levels directly influence blood pressure. High levels of low-density lipoprotein cholesterol and triglycerides make the blood viscous, slow down blood flow, increase pressure in the blood vessels, thus causing an increase in blood pressure. At the same time, low levels of high-density lipoprotein cholesterol (HDL-C), known as “good” cholesterol, cannot effectively clear excess cholesterol from the blood, increasing the risk of atherosclerosis and further elevating blood pressure.
Supported by Scientific Research
Several studies have shown a significant correlation between high saturated fatty acid intake and high blood pressure. A large cohort study involving tens of thousands of people found that those with a higher intake of saturated fatty acids had a significantly higher incidence of high blood pressure than those with lower intake. Additionally, clinical trials have confirmed that reducing saturated fatty acid intake can effectively lower blood pressure.
From this data, it is clear that a diet high in saturated fatty acids does increase the risk of high blood pressure. Therefore, for hypertensive patients, it is essential to control their intake of saturated fatty acids.
Dietary Recommendations for Hypertensive Patients: How to Scientifically Manage Diet to Maintain Health
For hypertensive patients, scientifically managing their diet is vital for controlling blood pressure. By meticulously choosing ingredients and controlling intake, blood pressure can effectively be maintained within a normal range.
Reduce Saturated Fat Intake
Saturated fats are primarily found in animal fats and some plant oils. A high intake increases LDL-C in the blood, leading to atherosclerosis and consequently raising blood pressure. Hypertensive patients should minimize consumption of fatty meat, full-fat dairy products, and high-fat snacks, opting for lean meats, skimmed milk, and low-fat products as substitutes.
Increase Unsaturated Fat Intake
Unsaturated fats have protective effects on the cardiovascular system, lowering total cholesterol and LDL-C levels. Hypertensive patients can moderately increase their consumption of foods rich in unsaturated fats, such as fish (especially deep-sea fish), olive oil, nuts, and seeds. It is recommended to consume at least two servings of omega-3 fatty acid-rich fish per week.
Control Sodium Intake
Excessive sodium intake is a significant factor causing high blood pressure. Hypertensive patients should limit their daily sodium intake to no more than 2000 milligrams, equivalent to 5 grams of salt. Reduce the intake of processed foods, canned foods, and pickled foods, as these often contain high levels of sodium. When cooking, use low-sodium salt or other seasonings like herbs and spices as alternatives to table salt.
Increase Intake of Potassium, Calcium, and Magnesium
Potassium, calcium, and magnesium have regulatory effects on blood pressure. Potassium-rich foods include bananas, oranges, potatoes, and spinach; calcium is primarily sourced from dairy products, tofu, and green leafy vegetables; magnesium can be obtained from nuts, whole grains, and legumes. Hypertensive patients should ensure their diet includes sufficient amounts of these minerals to help control blood pressure.
Consume More Vegetables and Fruits
Vegetables and fruits are rich in dietary fiber, vitamins, and minerals, helping to lower blood pressure. It is advisable to consume at least five servings of vegetables and fruits per day, selecting dark-colored vegetables and fruits such as spinach, carrots, blueberries, and tomatoes, as they contain more antioxidants beneficial for cardiovascular health.
Limit Alcohol Intake
Excessive alcohol consumption can raise blood pressure and is high in calories, contributing to obesity. Men should not exceed two standard drinks of alcohol per day, and women should not exceed one. One standard drink is equivalent to 350 milliliters of beer, 150 milliliters of wine, or 45 milliliters of spirits.

Daily Life Tips
Avoid Processed Foods
Processed foods often contain high amounts of sodium and saturated fatty acids. Try to choose fresh ingredients and cook at home. This not only helps control sodium intake but also ensures the nutritional value of the food.
Use Healthy Cooking Methods
Adopt steaming, boiling, stewing, baking, and other methods, avoiding frying and deep-frying, which can reduce fat intake. Use healthy fats like olive oil, limit the amount of oil used, with one tablespoon per cooking session.
Monitor Blood Pressure Regularly
Hypertensive patients should monitor their blood pressure regularly to understand their own blood pressure changes and make timely adjustments to their diet and lifestyle. Equip the home with a blood pressure monitor and measure at least twice a week.
Engage in Moderate Exercise
Moderate exercise is beneficial for blood pressure control. It is recommended to engage in 30 minutes of moderate-intensity exercise daily, such as brisk walking, swimming, or cycling. Exercise helps in weight management and improves cardiovascular function.
Maintain a Positive Mindset
Psychological stress can also affect blood pressure. Hypertensive patients should maintain a positive mindset and engage in relaxation activities such as listening to music, reading, or meditating to relieve stress.
By managing diet and daily life effectively, hypertensive patients can control their blood pressure, reduce the risk of cardiovascular diseases, and maintain good health.
