Femoral head necrosis has a nickname: “coronary heart disease of the femoral head”. The reason is that among patients with ischemic necrosis of the femoral head caused by various reasons, more than 85% of cases have abnormal liver function, which manifests as lipid metabolism disorders, and tiny fat droplets block the capillaries that nourish the femoral head, which is similar to coronary artery atherosclerotic heart disease (abbreviated as coronary heart disease) in patients with high blood lipids, hence the name “coronary heart disease of the femoral head This pathological change is similar to coronary artery sclerosis heart disease (abbreviated as coronary heart disease) in patients with high blood lipids, hence the name “coronary heart disease of the femur.
Therefore, lowering blood lipids can fundamentally improve the blood supply to the femoral head and facilitate the repair of necrotic bone.
Blood lipids include four groups of substances – triglycerides, glycerol, cholesterol, and free fatty acids. The hyperlipidemia we often mention generally refers to high cholesterol or triglycerides in the body.
Therefore, lowering cholesterol is an important measure in the treatment of femoral head necrosis.
In the clinic, we often encounter patients asking if there is a way to lower blood cholesterol without medication. The answer is yes! The way to lower cholesterol is in the little things of daily life. A bowl of oatmeal, a small handful of walnuts, etc. will become the scavenger in your blood vessels, removing the waste in your blood vessels, the culprit of coronary heart disease and femoral head necrosis – cholesterol.
Simple adjustments to your diet, along with regular exercise and other healthful habits, can lower cholesterol levels and allow necrotic femoral bones to repair themselves faster.
Here are just a few of the major types of foods that can significantly lower cholesterol
Whole grains such as oats
Soluble fiber in the diet of whole grains such as oats can reduce the absorption of cholesterol. A daily intake of 5 to 10 grams or more of soluble fiber can lower total cholesterol and LDL cholesterol and reduce the self-synthesis of cholesterol in the body.
Whole grains such as oats, barley, corn and millet are rich in soluble fiber, which can reduce the “bad cholesterol” (LDL cholesterol) that causes atherosclerosis, and oats in particular are richer in evidence. 1.5 cups of cooked oatmeal per day provides 6 grams of fiber, and if you add fruit such as bananas, you add 4 grams of fiber. Studies have shown that replacing pasta with 100 grams of oatmeal per day for 6 weeks can significantly reduce “bad cholesterol” and waist circumference.
Walnuts and other nuts
Walnuts and other nuts are rich in unsaturated fatty acids, saturated fat is very low, a moderate daily consumption of nuts, can reduce total serum cholesterol and bad cholesterol levels. After replacing 20% of total calories with walnuts for 4 weeks, total cholesterol dropped by 0.58 mmol/L and bad cholesterol dropped by 0.47 mmol/L. Recent studies have shown that patients with hypercholesterolemia can significantly lower their cholesterol by eating a little bataan wood (American almonds) every day compared to eating equal calorie desserts. Moderate daily intake of dried fruits (42g) such as walnuts, bataan wood, hazelnuts, peanuts and pistachios can reduce the risk of heart disease. However, do not consume salted or sweetened nuts. Nuts are high in calories and moderation is important. Avoid eating too many nuts that lead to weight gain, it is recommended to replace foods high in saturated fatty acids with nut portions, for example, walnuts or almonds instead of meat, kernels spinach and cashew nuts celery.
Foods rich in or with added phytosterols
Phytosterols are widely found in vegetable oils such as corn oil and sesame oil and in plant foods such as fruits and vegetables, legumes, nuts and grains. Phytosterols lower blood cholesterol by competitively inhibiting the absorption of cholesterol and do not affect HDL cholesterol levels. Daily intake of 1.5g-2.4g of phytosterols can reduce dietary cholesterol absorption by 30%-60% and reduce bad cholesterol by 10%-15%. The daily requirement of phytosterols is at least 2 g. The same effect can be achieved by adding phytosterols or sterol esters to foods, such as yogurt with added phytosterols.
Soy products
Soybean is rich in vegetable protein, unsaturated fatty acids, calcium and B vitamins, isoflavones, phytosterols and soy oligosaccharides and other healthful ingredients, and is an important source of high-quality protein in the diet. Soy has a hypolipidemic effect, the daily intake of soy products can reduce bad cholesterol by 5 to 7 percent. It is recommended to consume 30 to 50 grams of soybeans per day, which is approximately equivalent to 200g of tofu, 100g of dried tofu, 30g of bean curd, 700g of tofu brain or 800g of soy milk, respectively.
Vegetables and Fruits
Vegetables and fruits are nutritious, low in calories, rich in vitamins, folic acid and soluble fiber, and rich in antioxidants to neutralize free radicals in the body and reduce oxidative stress. An apple a day is comparable to the effect of statin lipid-lowering drugs. Many prospective studies have shown a negative correlation between coronary heart disease and stroke and vegetable and fruit intake. The results of meta-analysis showed that consuming an extra serving of vegetables or fruits (about 100 grams, 2 taels) per day reduced the risk of coronary heart disease by 4% and stroke by 5%. It is recommended to have at least two servings of fruits and three servings of vegetables per day. Two servings of fruits are preferably two fruits, and one serving of fruits refers to a fresh fruit equivalent to the size of a softball, for example, an apple. Three servings of vegetables are preferably three, for a total of one pound. One serving of vegetables is defined as 77g in weight and one serving of fruit is defined as 80g in weight.
Olive Oil
Olive oil contains powerful antioxidants that can lower the “bad” cholesterol but leave behind the “good” cholesterol. You can substitute 2 tablespoons (23g) for animal fat for heart health. Olive oil is high in calories, do not exceed the recommended amount. Extra virgin and virgin olive oils contain more antioxidants that are good for blood vessel health and are more effective in lowering cholesterol.
Deep-sea fish and other seafood
Deep-sea fish and other seafood are rich in fish oil, which is good for cardiovascular health. Although the omega-3 fatty acids in fish oil cannot lower “bad cholesterol”, they can lower serum triglycerides and raise “good cholesterol”, which is good for cardiovascular health and has a certain effect on the prevention of coronary heart disease. They are also effective in reducing blood pressure and the risk of blood clots. The American Heart Association recommends eating at least two servings of fish (100g each) per week. Omega-3 fatty acid rich mainly deep-sea fish, including: sardines, tuna, cod, salmon, scallops and swordfish.
Control the intake of meat foods and fried foods
Cholesterol and triglycerides do not exist alone in the blood, but are combined into lipoproteins, that is, mainly HDL and LDL. The higher the HDL is within a certain range, the better, because its main components are phospholipids and cholesterol which are good for the body, and the lower the LDL is, the better. What is commonly referred to as good cholesterol is high-density cholesterol, and bad cholesterol is low-density cholesterol.
Saturated fat raises total cholesterol, “bad cholesterol” and triglyceride levels and is high in some fats and oils such as beef, lamb, pork and processed meats, full-fat dairy products and palm oil and animal oils. Dietary intake of saturated fat controlled at 5% to 6% of total calories is more appropriate to significantly reduce LDL cholesterol levels. 50 kg adult male, pork as the only source of saturated fat, to achieve saturated fat provides 5% to 6% of total calories, the amount of lean pork per day is about 70 grams, not more than 500 grams per week; if you also drink whole milk, then The latest “Dietary Guidelines for Americans” released in 2015 recommends controlling cholesterol from food sources and avoiding cholesterol-rich foods such as animal offal, skin, brain and egg yolks and cream.
Trans fats raise “bad” cholesterol and lower “good” cholesterol, and the effect of raising bad cholesterol is comparable to that of saturated fats. In addition to the good taste of trans fats and all the harm, it is best not to eat. However, the food label does not specify trans fat, the ingredients list includes “palm oil”, “vegetable hydrogenated oil”, “margarine (cream)”, ” artificial fat”, “hydrogenated oil”, “shortening”, “refined oil”, “phytolipid ” etc., understand that these are trans fatty acids. Potato chips, French fries, fried products, some milk teas, margarine, cookies and cakes are high in trans fatty acids.
Adopt good lifestyle habits
Get proper physical exercise: stick to 30 minutes to 1 hour of exercise daily. Depending on the individual’s condition, either walking, cycling or swimming can achieve the purpose of exercise, but be persistent.
Quit smoking and alcohol: Smoking lowers HDL cholesterol (“good” cholesterol) levels; smoking also reduces the body’s tolerance for physical activity, making it more difficult to bring cholesterol down to healthy standards through exercise. Alcohol can promote liver cholesterol synthesis, which can increase blood lipids.
Live a regular life and maintain a good state of mind.
According to the blood lipid test, the physician should allocate the medication, and should never purchase the medication without permission to avoid adverse reactions.
