Biochemistry Fats, Diet, and Heart Disease

Biochemistry plump outs, Diet, and Heart Disease Fat can sometime be a word that gives people the chills when they construe about it. It is one of the three main sources of calories to our diet and a major(ip) part of ones dietetical requirement. There are three kinds of productive saturated, polyunsaturated and monounsaturated. The degree of saturation is dependent on the amount of double and multiply bonds in the chemical makeup. Saturated fats are known to increase the bodys levels of snag serum (blood) cholesterol. Along with cholesterol, saturated fats can deposit on the inner walls of blood vessels a condition known as atherosclerosis.When the mental objects arteries become clogged with cholesterol and fats, blood flow can be restricted or only blocked, leading to severe chest pain and heart attack. Polyunsaturated and monounsaturated fats truly have a cholesterol- dismaying effect. By substituting polyunsaturated fats for the saturated fats in your diet, you can ac tually help control cholesterol levels. Too some(prenominal) dietary fat can also contribute to weighed down. Being overweight can aggravate high blood pressure, place excess tense up on your heart, and make it more difficult to stay active and physically fit, thus having a negative impact on your overall cardiovascular health.For about three decades, health institutions like the American Heart Association, subject area Institutes of Health, World Health Organization, and opposites advised people to reduce dietary fat by limiting fat intake to fewer than 30 percent of daily calories. Their claim was that a low fat diet finally resulted in the reduction or elimination of risk for heart sickness although there wasnt much evidence to support the notion of low-fat diets in the beginning.In an oblige published in the Journal of the American Medical Association on February 8, 2006, in a 8th year Womens Health Initiative dietary Modification Trial, about 49,000 women with almost i dentical rates of heart attack, stroke, and other forms of cardiovascular disease were followed to see the effect of a low-fat diet and those not on the diet. Their results showed that women on the low-fat diet didnt lose or gain every more weight than women who followed their usual diets. The important thing to note from these kinds of studies was the reference of fat in the diet.For example the Mediterrean style diet is high in fat but these fats are from plant sources such as chromatic oil, nuts and seeds which are low in saturated fat intake. The western diet on the other hand has fats from animal sources which are unremarkably saturated and produces a higher risk for heart disease. In conclusion, as research grows on diet and heart disease, its becoming clearer that looking at at a single nutrient in isolation cannot show us the whole story about a persons heart disease risk. People eat foods, not nutrients, and they eat them in an overall dietary pattern.The traditional Mediterranean Diet pattern, in contrast, appears to lower the risk of heart disease, stroke, and metabolic syndrome, a constellation of factors that increases the chances of developing heart disease and diabetes. So if you are concerned about heart health, impart attention to your overall diet, not just to the type of fat. Citation Barbara, H. (2006) et al.
