Health is wealth. There is no denying fact that everyone wants a healthy life. But unfortunately, most of the people don’t know how to live healthy. You know, live healthy lowa has such a power which brings businesses, friends, families, communities very close to yourself. However, this article will tell you some essential facts about cholesterol and fats in order to live healthy.
There has never been anything more confusing communicated from the medical establishment to consumers than the discussion of cholesterol and fat in our diet. For nearly 40 years now we have heard little other than the harm that comes from consuming too much fat. Medical science has shown evidence that the higher your total cholesterol level and LDL (bad cholesterol), the greater is your risk of developing cardiovascular disease. As a result of all of the medical and media attention to the harmful aspects of fat in our diets, we have become fearful of fat. The reality is that not all fats are bad and to the contrary, fats are really very essential for our health. The body requires carbohydrates, proteins, and fats to survive. Fat is required to build our cell membranes, brain cells, nerves, and many of our hormones. Fat is not our problem, but rather the kinds of fat we consume. The biochemistry behind the different fats in our body will help differentiate between a good fat and a bad fat.
You know, cholesterol is an essential fat in several aspects of our health. Basically, it is a hard, waxy fat found in many animal products (especially egg yolks, meat and certain dairy products like milk) and it is also produced by our liver. Cholesterol is needed by the body for the production of hormones, for example, testosterone, estrogen, and cortisol and is also needed to make bile acids and cell membranes. The body actually uses cholesterol to help control the flexibility of the cell membrane. More cholesterol is added to the cell membrane if it is too flexible and will be removed if the cell wall becomes too rigid. This problem is accentuated even more for Americans who are deficient in the polyunsaturated good fats and eating too many trans-fatty acids.
For your kid information, cholesterol received its bad reputation because it is the type of fat that is found in the hardened plaque in the arteries. For this reason, elevated cholesterol levels have been believed to be the cause of hardening of the arteries leading to heart attacks and strokes. For the past decade we have all been trying to eat less fat and cholesterol in our diets. The ironic truth is that if we don’t get enough cholesterol from our diet our liver will produce what is needed. Therefore, the amount of cholesterol we get in our diet has very little, if any, influence on the amount of cholesterol we have floating around in our blood stream. Our cholesterol levels instead are primarily related to the amount of saturated fat and high-glycemic carbohydrates that we consume in our diet.
Very few free fatty acids can be found in our blood stream. Have you ever tried to mix oil or fat in the water? It doesn’t work well. Same thing happens in our blood for fat. Most of the fats are carried around in transport vehicles which are commonly known as lipoproteins. LDL or low density lipoproteins are the transport vehicles that carry these fats from the liver to the other cells of the body. HDL or High Density Lipoproteins picks up excess cholesterol and triglycerides that are in our blood stream and carries them to the liver. The liver is then able to metabolize the triglycerides and cholesterol further and either sends them out to other cells for their use or, in the case of cholesterol, can also excrete it in the bile.
Almost all of you have heard that LDL cholesterol is bad and HDL cholesterol is god. But the fact is both LDL and HDL cholesterol are simply transport vehicles for both cholesterol and triglycerides and both are really very important for moving fat around the body.
