Types of Fat and Cardiovascular Risk: Cholesterol
Cholesterol is a structural component of cell membranes of our body. In addition, after he made other important functional molecules, vitamin D, steroid hormones and bile acids in bile. That is, there is a cholesterol our body produces naturally and one that we get from food.
Cholesterol is transported in blood bound to proteins and other fats, forming the so-called lipoproteins. The best known by the general population are HDL-c or good cholesterol and LDL-c or bad cholesterol. HDL is considered good because they lead cholesterol from peripheral cells to the liver, preventing it from accumulating in the blood vessel walls. Read the rest of this entry »
Types of Fat and Cardiovascular Risk
The types of fat recommended for a healthy diet are the unsaturated fatty acids, there are different types but the most representative are the polyunsaturated (such as omega-3 fatty acids, characteristic of sea fish) and monounsaturated (especially oleic acid, present in olive oil and olives).
Polyunsaturated fats help reduce total cholesterol levels (both HDL-C, also called good cholesterol, and LDL-c or bad cholesterol) and triglycerides. In this group are the omega-6 fatty acid linoleic and omega-3, called EPA and DHA. In the omega-3 also includes the fatty acid linolenic acid, since from it our body produces fatty acids EPA and DHA. Linoleic (omega-6) and linolenic (omega-3) are essential fatty acids.
This means that our bodies can not produce by itself and must ingest them through food that make up the diet. Read the rest of this entry »

People Who Walk Slowly, More Prone to Cardiac Death
Walking slowly not only delay the arrival at destination: According to a French team, the greatest who walk slow are nearly three times more likely to die from heart disease than those who walk faster.
The message to the general population is to maintain fitness in old age would have important implications and preserve life and function (muscle).
The expert said the study, published in BMJ, also suggests that a test of walking speed can know better the health status of older patients.
Previous studies have associated the slow gait with an increased risk of death in a given period, as well as to falls and other adverse health consequences, but none had shown the highest risk if the concentrated heart disease or other cause .
Aspirin, just for heart patients
People who have no obvious cardiovascular problems should not take aspirin as protection, says a study.
Investigation of Drugs and Therapeutics Bulletin (DTB)-Drug and Therapeutics Bulletin, says that the drug can cause severe internal bleeding and does not prevent death from cardiovascular disease (disorders of the heart and blood vessels).
He added that doctors should carry out a review of all patients currently taking aspirin as a protective measure against heart disease. Eating a low-dose daily aspirin is already widely used to prevent episodes of these disorders in people who have had problems such as heart attacks or strokes.
This approach, known as “secondary prevention is well established and past research has confirmed its benefits.
However, it is believed that many thousands of people in several countries taking the drug as a protective measure against cardiovascular disease before showing any symptoms.
“There is growing scientific evidence shows that benefits can not be identified by the use of aspirin in patients who have suffered heart attacks or strokes in the past,” the BBC said Dr. Ike Ikeanacho, editor of the DTB.
“At best, aspirin has a slight potential benefit in these people. But this benefit is offset by a real risk of the drug, including internal bleeding,” adds the scientist.
