High Cholesterol Essay

In chapter 3 Dr. Moalem talks about how cholesterol rises too. Like when you consume alcohol, your body detoxifies it and then extracts calories from it. It's a difficult process that involves many different enzymes and a lot of organs, although most of the process takes place in the liver. First, an enzyme called alcohol dehydrogenase converts the alcohol into another chemical called acetaldehyde; another enzyme—cleverly called acetaldehyde dehydrogenase—converts the acetaldehyde into acetate. And a third enzyme converts

Dairy should not be a primary food group on the dietary guidelines set by the government because of its many negative effects on human health (given that people care about their health and the health of those around them). Dairy and other animal products are the only food sources which contain cholesterol. Arguments have been made saying that humans need to consume cholesterol in order to have a healthy balance of fats; these arguments fail to acknowledge that our bodies naturally produce all the cholesterol that it needs. And many studies have been conducted to support the theory that consumption of dietary cholesterol overloads arteries and can cause heart disease, artery disease, as well as sudden heart attacks. The Department of Community Health and Preventative Medicine at Northwestern University Medical School worked to interpret an international study based on data from the Food and Agriculture Organization and the World Health Organization. The overall conclusion was that “…dietary cholesterol levels are consistently related to CHD (coronary heart disease) mortality rates” (Stamler). A study conducted by Lena Ohlsson at the Laboratory of Gastroenterology and Nutrition within the prestigious Lund University in Sweden also linked dietary cholesterol and milk fat with artery disease and other metabolic disorders. In short, the abstract of her lab report said that low-density lipoprotein (LDL)—“bad” cholesterol—was found to be directly associated with coronary artery

People with high cholesterol are at greater risk of developing heart disease, according to the American Heart Association. People with diets high in saturated fats---like those in meat, dairy and eggs---are more likely to have high cholesterol levels. To reduce cholesterol, the American Heart Association recommends limiting the intake of saturated fat, trans fat and cholesterol, and eating more plant-based foods.

A decrease of corn chips and potato chips with an increase of 5-9 servings of vegetables a day can assist to reduce LDL level

“You're more likely to have high cholesterol that can lead to heart disease if you have any of these risk factors such as smoking, obesity, large waist circumference, poor diet, lack of exercise and diabetes.” (Mayo Clinic Staff)

The Framingham study and others that followed showed us that HDL-cholesterol is an independent cardiovascular risk factor and that the increase of HDL-cholesterol of only 10 mg/dL leads to a risk reduction of 2-3% (PubMed.gov, Nov. 2012). Higher levels of HDL cholesterol result in a risk of cardiovascular disease closer to the default risk. Cardiovascular disease risk increases then plateaus with greater ratios between total cholesterol and HDL cholesterol. Thus, higher levels of HDL cholesterol proportionate to levels of total cholesterol relate to lower cardiovascular disease risk (Lecture #3). Having a HDL-cholesterol of 60 mg/dL and above is the best place for a person to be. A bit lower, but considered a good HDL-cholesterol level standing is 40-49 mg/dL for men and 50-59 mg/dL for women. All three of us, me, my mother, and the case study Danny are in good standing regarding HDL-cholesterol levels, my mother with 55 mg/dL, me with 50 mg/dL, and Danny with 40

In a study conducted in 1985 observing primates, it was determined that the major effect of dietary cholesterol is its LDL raising effects. High intakes of cholesterol increase the number of circulating LDL’s and it can also change its size and composition. [12] It was during this time period that the mechanisms by which SFA are thought to increase blood cholesterol concentrations came about. One mechanism for the increase in LDL cholesterol levels is the suppression of LDL receptor activity. Studies in tissue cultures have shown that increasing the cholesterol content of a cell will down-regulate synthesis of LDL receptors. [13] This will lead to an increase in concentration of blood cholesterol. Another cause for an increase in blood cholesterol concentration through intake of dietary SFA is the composition of the newly secreted lipoproteins. With a high saturated fat intake, the LDL’s become rich in cholesterol esters, leaving the triglycerides in the blood. [14] The use of non-human primates in

Our body naturally produces cholesterol through the liver, we can also obtain cholesterol from consumed products. We need small amounts of cholesterol to produce hormones, bile, and vitamin D. Cholesterol doesn’t dissolve in the bloodstream once it is inside the body. It needs to be carried by two types of lipoproteins called low density lipoproteins(LDL) and high density lipoproteins(HDL). The more cholesterol we consume, the more LDL and HDL we produce. HDL is

High cholesterol can be avoided with many different easy ways that benefits the body in other ways. According to studies from NHBLI, saturated fats and diets high in cholesterol should be avoided to lower cholesterol. Saturated fat is the main reason of high cholesterol. Saturated means that means that it contains liquid, or is a a watery type substance. Eating cholesterol directly is also a main reason for high cholesterol after a person eats a meal that is very high in cholesterol. Studies from NHBLI prove that being more physically active can reduce the chances of high

There are two types of cholesterol, low-density lipoprotein (LDL) and high-density lipoprotein (HDL). LDL is

Cholesterol is a lipid that helps manufacture vitamin D on the surface of the skin, produces hormones, maintains cell membranes, and possibly helps cell connections in the brain.3 Based on what is known about calcium transporting throughout the body we can infer that cholesterol also has a similar process. When there is an imbalance of cholesterol homeostasis we can have high density lipoprotein (HDL) which is known as good cholesterol, or low-density lipoproteins (LDL) which is known as bad cholesterol. Lipoproteins differ in size, shape, composition, function, and contribute to vascular

I come from a very large Mexican family where there is a lot of meat, cheeses, fried food, butter and of course always a lot of sweets. Due to this diet there are many health related concerns in my family, three being diabetes, high blood pressure and high cholesterol, although high cholesterol seems to be more of a genetic issue rather than a food related one. Even so, the diet we maintain does not help lower it. Due to this diet and genetics, I have very high cholesterol myself; my doctor even shocked me by saying that I could have a heart attack by the time I’m 25. This obviously scared me and I knew then that there needed to be a change in my diet.

Foods high in LDL are food like steaks, and dairy products like cheese, they are high in saturated fat. Also trans-fat, which include milk, beef, and eggs. These are other foods that contain trans fatty acids that include, fried foods, bread, baked goods, cookies, crackers, chips, and vegetable shortening. (Timberlake, 2014, pg. 525)

One source of great mortality and morbidity in Europe and North America is the cardiovascular disease, Atherosclerosis. It is recognized as a chronic inflammatory disease of the intermediate and large arteries characterized by the thickening of the arterial wall and is the primary cause of coronary and cerebrovascular heart disease (Wilson, 2005). It accounts for 4.35 million deaths in Europe and 35% death in the UK each year. Mortality rate are generally higher in men than pre-menopausal woman. Past the menopause, a woman’s risk is similar to a man’s (George and Johnston, 2010). Clinical trials have confirmed that lipid accumulation, endothelial dysfunction, cell proliferation, inflammation matrix alteration and foam cell formation are

Atherosclerosis is a type of arteriosclerosis. Arteriosclerosis is a general term for the thickening and hardening of arteries. Atherosclerosis, or hardening of the arteries, is a pathological situation in which plaque builds up inside the arteries. Plaque is usually made of cholesterol, fatty substances, cellular products, calcium and fibrin (a clotting material in the blood). Atherosclerosis is the leading cause of mortality and morbidity from cardiovascular disease (CVD) around the world. The magnitude of this problem is so high that atherosclerosis claims more lives than all types of cancer combined and the financial burden are considerable1. It a complex, chronic pathological
