Cholesterol is a waxy, fat-like substance made in the liver and found in certain foods, such as from animals, like dairy products (whole milk), eggs and meat. The body needs some cholesterol in order to function properly. However, too much cholesterol can increase a person’s risk of developing heart disease. There are several factors that contribute to high cholesterol — some are controllable while others are not.
Uncontrollable risk factors
– Gender: After menopause, a woman’s LDL-cholesterol level (“bad” cholesterol) goes up, as does her risk for heart disease.
– Age: Your risk increases as you get older. Men aged 45 years or older and women aged 55 years or older are at increased risk of high cholesterol.
– Family history: Your risk increases if a father or brother was affected by early heart disease (before age 55) or a mother or sister was affected by early heart disease (before age 65).
Controllable risk factors
– Diet: The saturated fat and cholesterol in the food you eat raise total and LDL-cholesterol levels.
– Weight: Being overweight can make your LDL-cholesterol level go up and your HDL level go down.
– Physical activity/exercise: Increased physical activity helps to lower LDL- cholesterol and raise HDL-cholesterol (the “good” cholesterol) levels. It also helps you lose weight.
What is high cholesterol?
What are LDL and HDL cholesterol and triglycerides?
Cholesterol travels through your blood attached to a protein. This cholesterol–protein package is called a lipoprotein. Lipoproteins are either high density, low density, or very low density, depending on how much protein there is in relation to fat.
Low-density lipoprotein cholesterol (LDL) is called “bad” cholesterol because it can cause cholesterol buildup and blockage of your arteries. LDL is mostly fat with only a small amount of protein. By lowering LDL cholesterol, you can reduce your risk of atherosclerosis, heart attack, stroke, and other complications.
High-density lipoprotein cholesterol (HDL) is sometimes called “good” cholesterol because it helps prevent cholesterol from building up in your arteries. It is mostly protein with only a small amount of fat. HDL cholesterol helps clear the bad cholesterol from the body by picking up leftover cholesterol from the bloodstream and carrying it back to the liver for disposal. If you are at risk for heart disease, it may be beneficial to raise your HDL cholesterol levels. Low HDL cholesterol increases the risk of coronary artery disease. High levels of HDL appear to help protect against atherosclerosis, heart attack, stroke, and other complications.
Triglyceride is one kind mixture, it is composed by three fatty acids and glycerine. The triglyceride has composed the major part from animal and the vegetables fat, it is the main lipin of the blood flows. The triglyceride and the protein union may compose the highly concentrated lipoprotein (HDL, beneficial cholesterol) and low density lipoprotein (LDL, harmful cholesterol). As for an adult in the blood gathers the triglyceride content is, every 1,/10 liter of blood contains 200 milligrams of triglycerides.
The blood content of triglyceride may reduce through the diet. Low fat, low alcohol, low sugar in diet can reduce the triglyceride in the blood. Take more fruits, vegetables and grains can reduce the triglyceride content in the blood, as it can reduces heart disease risk as well.
What are the symptoms of high cholesterol?
Generally, high cholesterol is a “silent” condition that rarely causes its own symptoms. As a result, many people do not realize that they have high cholesterol.
You may, however, have symptoms caused by a serious illness associated with high cholesterol, such as atherosclerosis, stroke, peripheral arterial disease, or inflammation of the pancreas. Atherosclerosis is a narrowing of your arteries that can lead to coronary artery disease (CAD). Unfortunately, by the time you have symptoms of CAD, such as chest pain, the arteries in your body are usually severely diseased already. Your first symptom of high cholesterol could be a heart attack or a stroke.
Inherited forms of high cholesterol, such as familial hypercholesterolemia, can cause physical signs that you or your doctor may notice. The most common is the formation of xanthomas, which are cholesterol deposits below the skin.
What lifestyle changes will I have to make?
First, patient should carry on the diet adjustment, improvement life style as well as control performs to the above influence factor. At the same time, carry on the medicine treatment again. This includes:
(1) Take less high fat food: Strictly choose content low cholesterol food, like vegetables, bean product and so on, especially vegetables with high fibers . It may reduce absorption of cholesterol in the intestines.
(2) Take less sweet food: The sugar may change into the endogen triglyceride in the liver relay, makes in the blood plasma the triglyceride density to advance, meets the limit sweets taking in.
(3) Reduces body weight: Person who is overweight, should under the doctor instruction to reduce body weight, 1 ~ 2 kilograms each month is most suitable. The principle diet to reduce weight is low fat, low sugar, have enough protein.
(4) Increase the physical strength activity and the exercise: The physical strength activity not only can increase the consumption of the heat energy, moreover strengthen the organism metabolism, enhances in certain vivo enzymes, lipoprotein esterase activeness, in particular advantageous to the triglyceride transportation and the decomposition, thus reduces the lipin in the blood.
(5) Quit smoking & have a little of wine: Right amount of wine, may make high density lipoprotein in the blood serum obviously to advance, reduces the low density lipoprotein level. Therefore, right amount of wine is possible to cause the coronary disease the prevalence rate to drop. Excessive drinking or drinks wine for a long time, may stimulate the liver to synthesize the more endogens triglyceride, makes in the blood the low density lipoprotein density to advance causes the high cholesterol sickness. Therefore, the middle-aged person is not encourage to drink.
(6) Avoids from hypertension: Intense of the mood, overexcited, may cause the cholesterol and the triglyceride content in the blood increase. Apply small dosage of the sedative for this kind of situation.
Top 5 Foods to Lower Your Cholesterol
TOP 1: Oats
Oatmeal is full of soluble fiber, which we know lowers LDL levels. When you digest fiber, it becomes gooey. Researchers think that when it’s in your intestines, it sticks to cholesterol and stops it from being absorbed. So instead of getting that cholesterol into your system — and your arteries — you simply get rid of it as waste.
TOP 2: Omega-3
Vegetable base omega-3 fatty acids (flaxseed)
Omega-3 fatty acids have been shown to lower triglycerides, which are a type of fat in the bloodstream. Omega-3 fatty acids may also slow down the growth of plaques in the arteries and reduce inflammation throughout the body.
TOP 3: Soy Protein
A number of studies show that soy protein may lower “bad” LDL cholesterol and triglycerides without lowering “good” HDL cholesterol.
TOP 4: Walnuts
Walnut not only can strengthen the brain, cosmetology. The newest research also discovered, often eats the walnut can reduce the human body cholesterol, protects the cardiovascular.
TOP 5: Plant Sterols and Stanols
For nearly 50 years it has been known that plant sterols and stanols, also called phytosterols and phytostanols, lower blood cholesterol levels by partly blocking absorption of cholesterol in the gut. Now, they are widely available in a range of food products for those who want to lower their cholesterol levels. The soybean and the coarse edible grain all are the plant sterols and stanols main origin.
