Cholesterol of plant can help you health and longevity

Filed cholesterol, perhaps most people are familiar with, some people can be clearly and logically to say what foods are high cholesterol, the harmful effects on human beings.
However, when plants cholesterol, I am afraid that people know very much. Cholesterol What exactly is a plant component? Plants What are the benefits of cholesterol on the human body? What are high cholesterol content in food plants? See nutrition expert analysis introduction.

Plant cholesterol - lowering blood cholesterol

As the name suggests, plant cholesterol is present in plants similar to cholesterol substances (scientific name plant sterols), the chemical structure of plant sterols and cholesterol are similar, but different role and cholesterol. Plant sterols are a big family, there are 70 kinds of natural plant sterols structurally similar, but the content is high, and the study included relatively clear β sitosterol, vegetable oil sterols stigmasterol and so on.

Plant sterols is an active ingredient in plants, is quite beneficial to human health. Found that plant sterols have lower blood cholesterol, inhibit breast proliferation and modulate immune function and so on. Which lower cholesterol is the most definite conclusion. Research has shown that plant sterols and cholesterol in the intestine can be competitive, to reduce cholesterol absorption, can effectively reduce the blood in patients with hyperlipidemia "bad" cholesterol - total cholesterol and low density lipoprotein cholesterol - the content without affecting the blood's "good" cholesterol - high density lipoprotein cholesterol - levels of hyperlipidemia in patients with good lipid-lowering effect. According to statistics, diet, plant sterol intake, the more risk of heart disease and other chronic diseases, the less the risk. Currently, many international organizations and scholars have suggested that high intake of food containing plant sterols to reduce the incidence of chronic diseases including coronary heart disease.

High levels of plant sterols which food

Cereals in the cereal, the flour content of plant sterols is much higher than rice, wheat flour per 100 grams of plant sterols in the average content of 59 mg. The more sophisticated processing, lower levels of plant sterols. The whole wheat flour> standard powder> prosperous powder> dumpling powder>. Per 100 grams of different brands and the origin of rice, roughly the same levels of plant sterols, an average of 13 mg. Cereals, such as Zimi, Yiyiren, buckwheat, barley, millet, corn and other plant sterols were higher, on average more than 60 mg.

Nutrition recommendations: our dietary guidelines, recommended adult daily intake of 300 to 600 grams of food grains. In accordance with an average of 400 grams, if the flour is the staple food intake is approximately 480 mg of plant sterols, if simply eating the rice, then the intake of less than 110 mg of plant sterols, the two differ greatly. Staple food is rice for residents, three meals a day at least one meal should be replaced by pasta, such as noodles, bread, etc., at dinner, you can also add some purple rice, small rice, corn powder grains, so the more reasonable.

According to the determination of all plant foods contain plant sterols, but the high content of vegetable oil beans, nuts, etc., although the grains, fruits, vegetables, the relatively low levels of plant sterols, but because their daily food consumption large, but also to provide mankind with a lot of plant sterols.

Beans legumes grains of plant sterol content than higher per 100 grams of soybean, the plant sterol content of more than 100 milligrams, black beans and green beans are also high levels of plant sterols. Tofu is the most common soy products, tofu per 100 grams of plant sterol content was also 30 mg. Although the water more than milk, but the content of plant sterols to 7 mg. Although China is the hometown of soybean, but the daily intake of Chinese residents was only 4 grams of dried beans, soy products is 11? Yan 8 grams, intake or seriously inadequate.

Nutrition recommendations: normal intake of soy products and more. Such as a cup of soy milk per day (250 grams), can provide about 20 mg of plant sterols. At least three times a week to ensure food tofu, each intake of 50 grams. Not only increased intake of plant sterols, but also provide high quality protein and other nutrients. Also often cook some miscellaneous Douyu, as catering or refreshments.

Fruits and vegetables: fruits and vegetables are important foods in the daily diet. They not only provide rich nutrients such as vitamins, and cellulose, but also provide plant sterols. Compared with other foods, fruits and vegetables in the moisture content of large, relatively low levels of plant sterols, but because of people's consumption is also large, and its role can not be ignored. Vegetables, cauliflower, broccoli, lettuce and other relatively high levels of plant sterols. Wax gourd, eggplant, bell peppers, etc. lower levels of plant sterols. Fruit, orange, orange, hawthorn and other relatively high levels of plant sterols, watermelon, cantaloupe and other lower levels of plant sterols.

Nutrition recommendations: eat 400 to 500 grams of vegetables, fruits, 100 ~ 200 grams. At present our residents is generally low intake of vegetables and fruits, such as intake of less than 300 grams of vegetables, fruit and only 45 grams. Whether increased vitamin, mineral intake, or increased intake of plant sterols, we should eat more fruits and vegetables, choose cauliflower, oranges and other relatively high plant sterol content of food.

Vegetable oil vegetable oil is one of the highest levels of plant sterols foods. To common per 100 grams of vegetable oil, for example, soybean oil and plant sterol content was about 300 mg; peanut oil 250 mg; sesame oil and canola oil for more than 500 mg. Can be said that vegetable oil is the diet an important source of plant sterols.

Nutrition recommendations: daily intake to 25 grams of vegetable oil is suitable. At present, both urban and rural areas have more than the intake volume of the big cities even more serious. Vegetable intake too much will cause excessive heat, increasing obesity and chronic diseases such as cardiovascular disease incidence. So, do not blindly increase the intake of vegetable oil in order to get more plant sterols. Appropriate adjustments to the reader the type of edible oil, such as corn germ oil, or rapeseed oil as the main cooking oil, if you replaced every 25 grams of peanut oil corn germ oil, you can change the case of calorie intake more intake of 100 mg of plant sterols.

Cholesterol "Good" and "Bad"

Cholesterol than animals, plants also contain cholesterol, steroids and the valley known as the bean steroids, they are absorbed in the small intestine, have lower blood cholesterol, the body is for the good.

Modern people are often scared of the cholesterol that it is detrimental not a profit thing, in fact this is a bias. High cholesterol level is to promote atherosclerosis, diabetes increased in heart, brain, the risk of lower limb vascular complications, but it is also the human body there must be one of the few nutrients.

Cholesterol is an important component of body cell, the synthesis of vitamin D and helps digestion important source of acid, synthesized in the body is an important material for the adrenal cortex hormones.

Moreover, cholesterol is not just from food, most of their synthesis in vivo, it limits the amount of cholesterol in the entry can only partly reduce blood cholesterol levels. Therefore, cholesterol is relatively limited, mainly suitable for patients with high blood cholesterol, such as blood cholesterol higher than 250mg/dl, or on the body of harmful LDL are higher and the body has a protective effect on high-density lipoprotein low patients.

Generally, patients as long as eating food with high cholesterol, such as organ meats, egg yolks, fish roe, crab, etc. on it. Cholesterol than animals, plants also contain cholesterol, steroids and the valley known as the bean steroids, they are absorbed in the small intestine, have lower blood cholesterol, the body is for the good.

High cholesterol eat eggs will get heart disease?

Some on the heart health of seven kinds of ideas, some correct and some wrong, see what your idea needs to be updated.


These four approaches are wrong

To maintain a healthy heart, I just abide by a low-fat diet on the line

Have a heart-healthy recipes need to include a useful body fat. To efforts to control the intake of saturated fat because saturated fats raise cholesterol levels. To avoid the intake of trans fatty acids (many processed biscuits, cookies and other snacks in there), this fat is particularly dangerous. Try to unsaturated fats (olive oil, canola oil, peanut oil, sesame and corn oil, nuts, etc.) instead of saturated fat, which helps lower cholesterol levels. In addition, we control the calories and food intake, which is composed of an important factor in heart-healthy recipes.

Never allow yourself to be the only way to eat

If you usually can keep the heart healthy recipes, and occasionally eat a rich dessert or a steak is no problem. Eat nuts, dark chocolate and drink alcohol are also good for the heart, as long as you, but quantity.

My total cholesterol level is low, you can sit back and relax

Total cholesterol level can not fully reflect the situation. Depends on LDL (low density cholesterol) and HDL (high density cholesterol) levels, the former high levels increase the risk of coronary heart disease risk, if the latter is high, we can reduce this risk.

You can have unlimited consumption of heart-healthy olive oil and canola oil

Even if the "good" fat in also contains some saturated fat. And vegetable oils contain saturated fat with calories contained in the same.

These three views are correct

Egg damage the heart as previously thought not serious

Eggs not previously thought the heart killer. Nutrition experts recommend a daily intake of cholesterol of 300 mg or below in each egg yolk contains 215 milligrams of cholesterol, so you eat 2 to 3 week egg is appropriate.

Using margarine instead of butter will help lower cholesterol.

Overall, soft or liquid margarine that contains saturated fat than hard margarine, which may contain harmful trans fats. Nutrition experts suggest that as consumption of margarine containing plant sterols, which help lower cholesterol.

If you are concerned about their cholesterol levels, reducing saturated fat diet lowers cholesterol more important than

The saturated fat in food than anything you eat can increase blood cholesterol levels are.

To heart health, you should consider adding the following five kinds of table is conducive to cardiovascular health food, should also eat three kinds of food.

5 kinds of food should eat

--- American Heart Association recommends fish and more fish, especially salmon, mackerel and albacore tuna are more like fatty fish, eat at least twice a week. These fish are rich in Ω-3 fatty acids can reduce the risk of coronary heart disease.

--- Recent studies have found that soybean, soybean, soy milk, soy products like tempeh can reduce the body's total cholesterol and LDL levels while raising HDL levels. U.S. Food and Drug Administration to allow soybean producers in the product package statement, the daily intake of 25 grams of soy protein can reduce the risk of heart disease.

Beans and nuts --- Researchers at Harvard School of Public Health following a heart attack on a group of survivors of the investigation. Their latest survey found that eat 1 / 3 cup dried beans can reduce the risk of heart attack 38%. Almond, pecan and peanut all help to protect the heart, but only for a day to eat one (about 42.5 grams).

--- Oats contain oat fiber not only reduces the body's total cholesterol and LDL levels, but also lower blood pressure.

--- Garlic Garlic contains compounds that help lower cholesterol. The researchers also noted that garlic had lower blood viscosity and antioxidants, can prevent a heart attack.

The three kinds of food should not eat

Red meat: The meat contains a lot of blocked arteries of saturated fat, is not conducive to heart health.

Soft drinks: soda contains a lot of simple sugars and calories, obesity among children and adults is one of the food.

French fries: French fries contain saturated fat and trans fat, will cause people to obesity, increased risk of heart disease.

A cup of soy milk a day to lower cholesterol

You want to lower your cholesterol, change in eating habits can do to help you? In general, changes in eating habits can lower cholesterol from 10 to 20 percent. Here are the five best foods to lower cholesterol.

Soybean

Research shows that daily intake of about 25 grams of soy protein can lower cholesterol. "Now the market, there are a lot of soy products high." A registered dietitian, said. Supermarket, you can buy soybeans, soy nuts, soy ice cream and cereal, biscuits and soy protein to do the fries.

Legume

Beans of any kind of beans and lentils. Recommended to eat three half-cup per week, were beans, you do not cook, use canned beans or some cake on it. A week, eat more rice, beans or tofu or a meat eating food, which really is very magical beans.

Oat

High-containing water-soluble oat fiber, soluble fiber like a sponge, it can actually absorb cholesterol, and the discharge of your cholesterol in vitro. 3 grams of oat fiber per day can lower cholesterol and LDL cholesterol. In other words, every day you should eat a half cup of cooked oatmeal.

Nuts

Single-fat, can lower LDL and raise HDL cholesterol. Single fat in nuts and seeds in general (pumpkin, sunflower, etc.), avocados and various oils, such as vegetables, olive oil, safflower, sunflower and rapeseed. But this does not mean you can afford to eat these foods.

Functional Foods

In the food sector, a condition known as "functional food" products. This food is to make people more healthy or more pleasant and designed, it can prevent diseases.

Each of these foods good for your health. But do not forget to develop a balanced and healthy diet, even if you have already put the food on the diet plan, but that does not mean you can not eat other food restrictions, you must also minimize eat those carbohydrates, sweets, Pork class and fried foods. Lower cholesterol, you should eat these foods, they can also help you lower blood pressure, improve cardiovascular health.

Reasonably good cholesterol diet

 The lack of thorough briefing, many people fear food containing cholesterol: stay away from fat, even when eating eggs, eating egg white, throwing away the yolk. But there are longevity, said once a month to eat pig heart, liver, stomach and the like. In the end should look at how cholesterol? Experts pointed out: "In fact, cholesterol is not entirely harmful to human things, in a nutshell, more is not good, not do less, the key is to eat!
Lack of cholesterol: the elderly lose memory

Cholesterol is a lipid in food, most of the body's own synthesis, in part through dietary intake. Animal foods and plant foods, contain steroid substances.

Among them, the animal food such as pork, beef, mutton, eggs and animal organs in animals with steroids, called cholesterol; plant food such as noodles, bean contained plant sterols, called Valley corticosteroids or steroids beans; bacteria category such as fungus, mushroom, seaweed within the steroids, called ergosterol.

Cholesterol is a component of brain cells, brain cells of nutrients. Lack of cholesterol, can cause fetal damage, dementia children, the elderly lose memory. Therefore, children, pregnant women and the elderly high cholesterol should be more appropriate. Synthesis of cholesterol or steroid hormones in the body of raw materials, without it, no synthetic hormones. No hormones, it would be "men are not men and women are not women," the.

Cholesterol: "good" and "bad" parts

Cholesterol is not alone in the bloodstream, combined with the lipids. Case: combined with phospholipid, said high-density lipoprotein cholesterol, which can drive away the vessel wall, plays a clear role in blood vessels; the other is low-density lipoprotein, it is easily in the vascular wall precipitation, resulting in arterial occlusion. Normal coronary heart disease patients, low-density lipoprotein levels in the blood is relatively high.

The elderly: intake of cholesterol diet

Food cholesterol into the human body, and will not immediately turn into blood cholesterol, but also after some digestion and absorption. A healthy adult, the body's cholesterol is about 50q-80Qo it has two blocked: One day removed from the body through the intestine, and second, the whole body through the liver.

Under normal circumstances, the synthesis of cholesterol in the human body has its own regulatory function: cholesterol intake more food, the body will reduce the number of synthesis: cholesterol intake of less food, they synthesized much more. Therefore, a metabolism of normal people, the number of cholesterol intake, will not affect too, as long as the Society of diet can match with the swap.

However, the elderly endocrine and lipid metabolism, reduce, easily lead to self-regulatory function of the disturbance. In addition, long-term nerve excessive pressure, hypertension, obesity, genetics, and little activity, also cause dysfunction of this self-regulation, then, if more than dietary cholesterol intake, will cause blood lipid cholesterol increased gradually Atherosclerosis. In this case, control of dietary cholesterol intake will be very necessary.

With good food: reducing cholesterol synthesis and absorption

The cholesterol content in food is not stereotyped. Animal cholesterol content in different organs are different than the protein in egg yolks, caviar higher than the fish muscle, crab meat, crab Wong higher than in Ukraine mullet fish eggs high.

Different parts, cholesterol levels are not the same as seed shrimp, shrimp brain, Ukraine eggs, egg yolk cholesterol more, while a smaller part of the body activities, such as beef and mutton legs stick, Heliconia, etc., lower cholesterol . This can be selected, to avoid foods with cholesterol and more.

Eat meat and vegetarian dishes with food in mind, do not just eat a food, should pay attention to animal food, including dietary fiber with high and contains vitamins, trace elements and more vegetables, fruits, beans, whole grains and other food to eat. This helps the excretion of cholesterol, can reduce cholesterol synthesis and absorption.

For example, the eggs contain cholesterol, fasting should not eat in the morning, so easily and quickly absorbed into the intestine, but should contain fiber and eat more vegetables. Again, garlic fried eggs fried eggs than good, because the garlic over fiber to the stomach to stimulate eggs to go down, increase drainage, reduce absorption.

High cholesterol do not eat more squid

Stall on the delicious roasted squid string is a lot of people love to eat. However, people with higher cholesterol to note that eating should be minimal, because each contained 100 grams of squid, 233 mg cholesterol, than we generally think of pork with high cholesterol but also around twice.

Cholesterol is essential for the maintenance of human health and substance, it can synthesize vitamin D, calcium and phosphorus metabolism of the body involved in promoting the development of bones and teeth play an important role. In addition, the synthesis of sex hormones in the body, cholesterol has also played a very strong effect. However, we all know, cholesterol intake more, it will lead to hypercholesterolemia, and thus the formation of coronary heart disease and other so-called "rich man's disease." For a healthy person, the daily intake of no more than 500 milligrams of cholesterol is beneficial to health; while hypercholesterolemia (plasma total cholesterol that exceeds 200 mg / 100 ml) patients, the daily cholesterol intake must not exceed 300 mg, can guarantee will not let illness worse.

Cholesterol mainly in animal foods, plant foods such as rice and flour and other cereals, vegetables, fruits and nuts in little. As living standards improve, people eat more and more animal food, but what are the high cholesterol content, content which is low, many people are not very clear. In addition to other squid, egg yolks, liver, pig brains, Crab, etc., are all relatively high cholesterol content, per 100 grams in total cholesterol levels above 200 mg, in particular the Crab and pig brains, which were 466 cholesterol mg and 2571 mg. Shrimp, pork intestines, pig haunch moderate cholesterol, 100 grams of food per 100 milligrams to 200 milligrams. Octopus, sea cucumber, milk and other foods low cholesterol levels, all in the 100 mg or below.

Although high cholesterol levels, but after all squid are high in protein and low fat nutrition, the health benefits, as long as the amount of food, patients with hypercholesterolemia not over 50 grams per day, can be healthy, can enjoy delicious.

Note: often heard music to lower cholesterol

According to the United States, "Health Day" Web site reported that listening to music not only mold character, can lower cholesterol levels, play a role in improving heart health.

Researchers at the University of Maryland survey of nearly ten thousand local residents, their average age of 36 years. The results showed that regular listening to your favorite music, their blood vessel function of transport than those who never listen to music 26%. Researchers analyzed, music can increase blood levels of nitric oxide, and nitric oxide to help prevent blood clots, reduce "bad cholesterol" in the accumulation of blood vessels. The study also found, often heard, "Red Hot Chili Peppers," and Madonna's music, can increase endurance; and 18th-century symphony, you can improve the brain's attention; but heavy metal music and make high blood pressure, unhealthy.

The study leader, Michael Miller said that although the music elevated the role of nitric oxide lasted only a few seconds, but the cumulative effect will last for a long time, but also beneficial to people of all ages. Therefore, he suggested that people in his spare time, may wish to listen to on a daily half-hour of music.
