Excessive iron is bad for the heart (article source: Xinhua News Agency, Beijing)

A recent study by American scientists shows that foods with excessive iron are prone to heart disease.

Dutch scientists have found that when a gene in the human body mutates, the possibility of suffering from heart disease doubles. This gene is associated with a hemochromatosis, which causes patients to consume too much iron from food. Generally, the human body contains 2 to 4 grams of iron, and the iron content in patients with hemochromatosis is as high as 20 grams. In the United States, one in every 3,000 people suffers from this disease.

High-fat breakfast is easy to induce heart disease (article source: Sichuan Daily) □ Pu Zhaohe

"Have a good breakfast" is a popular view. Recently, Dutch scientists suggested that eating too much fat for breakfast may induce heart disease, because all fat is malignant.

Nutritionists at the University of Heneghan in the Netherlands believe that it doesn't matter what kind of fatty oil you eat, whether it is animal oil or vegetable oil. It is quantity that plays a decisive role. Because the high fat content in food will lead to the increase of coagulation factor VIIIA, which will lead to the sharp increase of thrombin, and this enzyme plays a catalytic role in blood clots that cause infarction.

The researchers divided 9 1 elderly women into two groups for testing. The first group ate a hearty breakfast with 50% fat before blood test. At this time, the content of v ⅱ a in their blood is greatly increased. The other group only ate low-fat foods, such as yogurt, fruits and cereals. As a result, the content of V Ⅱ A after breakfast was significantly lower than that before breakfast.

Last year, researchers did a similar experiment: subjects ate four kinds of breakfast, each of which was provided with 50% calories by fat, but the types of fatty acids were different, including highly saturated animal fat, stearic acid, linoleic acid and linolenic acid. Breakfast includes buns, margarine, ham, cake and orange juice. The experimental results show that all fats increase coagulation factors, and there is no difference in the types of fats.

Patients with heart disease should not take too much calcium (article source: article excerpt)

A large number of scientific studies have confirmed that calcium deficiency in people's daily diet leads to hypertension, so many clinicians advocate that patients with cardiovascular diseases should have a high calcium diet. However, Professor Clausing of Stanford University and others found that excessive calcium supplementation in patients with heart disease can lead to sudden death.

Professor Clausing pointed out that there are 200,000 fatal heart disease patients in the United States every year, mainly due to cardiac ischemia, and the concentration of carbon dioxide suddenly rises, resulting in a large number of calcium ions flowing into myocardial cells and sudden death due to calcium deposition. Some scholars pointed out that heart patients with signs of sudden death should take low-dose calcium antagonists for a long time to reduce the occurrence of sudden death. Therefore, patients with cardiovascular diseases such as hypertension and coronary heart disease should take calcium supplements or calcium agents reasonably under the guidance of specialists to achieve the purpose of lowering blood pressure.

Smoking can also cause cardiovascular disease (article source: Beijing Youth Daily) ■ Text/Xiao Baiyun

As we all know, smoking may cause lung cancer, but you may not know that smoking also harms the cardiovascular system. It can lead to the following cardiovascular diseases:

Autopsy study of prospective follow-up of atherosclerosis and retrospective investigation of smoking show that smoking is closely related to atherosclerosis. Smoking can promote the formation and aggravation of atherosclerotic plaque on arterial wall. Some people have studied the relationship between smoking and myocardial arteriole injury, and found that arterial wall lesions, fibrosis and thickening, atherosclerosis, calcification and vitreous thickening are closely related to smoking. The World Health Organization pointed out that the dual effects of smoking and overnutrition have a positive effect on the development of coronary atherosclerosis, especially for mental workers.

Smoking is one of the three independent factors of coronary heart disease. A large number of studies have proved that smoking can work independently regardless of other risk factors. Smoking is responsible for 30% of the death rate of coronary heart disease in the United States, and the death rate of coronary heart disease of smokers is 70% higher than that of non-smokers. There is an obvious dose-effect relationship between smoking and mortality of coronary heart disease. The more years of smoking, the greater the total mortality of coronary heart disease.

Nicotine and carbon monoxide in the smoke of cerebrovascular disease can cause cerebral arteriosclerosis and vascular stenosis, and carbon monoxide can reduce the blood oxygen content, leading to hypoxia and functional decline of brain cells. According to the research of American Cancer Society, the mortality rate of cerebrovascular diseases of smokers is higher than that of non-smokers, and the mortality rate of stroke soon drops to the level of non-smokers after quitting smoking.

Peripheral atherosclerotic disease Smoking is the strongest inducing factor of peripheral atherosclerotic occlusive disease. Smoking damages the function of liver cells, leading to hyperlipidemia and peripheral vascular diseases. Investigation shows that the clinical manifestations of smokers appear 8- 10 years earlier than those of non-smokers. The influence of quitting smoking on peripheral arterial occlusive disease is indirect, and the risk of peripheral vascular disease of smokers is gradually close to that of non-smokers.

Low-fat diet is not conducive to coronary heart disease (article source: Life Times) Han Yang

Some patients with coronary heart disease think that the diet should be low in fat and cholesterol, so they dare not eat meat, eggs, milk and even vegetable oil, so that their bodies are getting thinner and thinner. As a result, people's hemoglobin is very low, and the oxygen content of myocardial blood supplied by coronary artery is reduced, causing myocardial ischemia. In this state, it can only be compensated by accelerating blood circulation. Increased blood circulation will naturally increase the workload of the heart, thus forming a vicious circle. Severe anemia can also lead to anemic heart disease in people with healthy hearts, which is more harmful to patients with coronary heart disease. Therefore, it is incorrect for patients with coronary heart disease to overemphasize the low-fat and low-cholesterol diet.

What are the dietary requirements of patients with hypertension and heart disease?

Dietary recuperation of patients with hypertension and heart disease should be based on specific conditions. Generally speaking, we should pay attention to the following issues:

(1) Controlling the amount of salt The main components of salt are chlorine and sodium. If the sodium salt intake is too much, under the action of some endocrine hormones, it can cause arteriole spasm and raise blood pressure.

Stand up. At the same time, sodium salt also has the function of absorbing water. If you take too much sodium salt, you will store water in your body, which will increase the burden on your heart. Therefore, the supply of sodium salt in daily diet should be less than 3 grams; Salty foods such as pickles, pickled mustard tuber and bean curd with soy sauce are best eaten less or not.

(2) Controlling the supply of heat energy Patients with hypertension and heart disease should eat more foods with low calories. When the total heat energy is too high, serum cholesterol usually rises. If the patient is overweight, he should control his diet.

(3) Limit the amount of fat and cholesterol. Try to avoid eating foods containing animal fat and high cholesterol, such as animal fat, fat, liver,

Kidney, brain, lung, egg yolk, roe, etc. Edible vegetable oil and bean products can be used. But vegetable oil should not be too much, because too much vegetable oil will also make patients obese.

(4) Avoid irritating food. Try to use less spicy condiments such as ginger, pepper and pepper noodles in your diet. Smoking and drinking are strictly prohibited, and bad things such as drinking strong tea and strong coffee are removed.

Hobbies.

(5) Eat more fresh vegetables and fruits, and often eat some fresh vegetables, fruits, bean sprouts, kelp, laver, fungus and other foods to prevent arteriosclerosis. Ordinary food

Using celery, weeds, tomatoes and other foods can lower blood pressure. Patients with heart disease should eat more fruits, such as hawthorn, Rosa laevigata and grapes.

Dietary factors to avoid rheumatic heart disease

(1) Do not eat bitter, cold and spicy food: Most patients with rheumatic heart disease have deficiency of heart and spleen. If they eat too much bitter cold food, it will damage the yang of the human body and aggravate the condition. In addition, foods such as peppers and mustard will make the heart beat faster and increase the burden on the heart. Moreover, this food will cause constipation, because it is difficult to defecate too hard, which will increase the burden on the heart and even cause accidents. ?

(2) Strictly control the intake of salt: strictly control the amount of salt, and also strictly limit the amount of various foods pickled with salt, so as not to cause water and sodium retention in the body and increase the burden on the heart.

(3) Quit smoking and drinking, strong tea and coffee: Because when cigarettes burn, they can produce a lot of carbon monoxide. After carbon monoxide is inhaled into the body, it can cause systemic vasoconstriction, combine with hemoglobin in the blood, and reduce its function of transporting oxygen, resulting in myocardial ischemia and hypoxia, which is not good for the heart. Exciting and stimulating drinks such as wine, strong tea and coffee can raise blood pressure, enhance the excitability of nervous system, lead to an increase in heart rate and even induce arrhythmia, thus increasing the burden on the heart and damaging the function of myocardial valves. Therefore, patients with rheumatic heart disease should ban smoking and excite stimulating drinks.
