Discuss the Link of Coronary Heart Disease and a High Fat Diet
First of all, what is a coronary heart disease? Coronary heart disease is when the artery starts to get narrow because of the fat that builds on to it (British Heart Foundation, 2015). As artery is a major oxygenated blood transporting vessel, coronary heart disease can lead to insufficient oxygen and blood flow to the heart and around the body. The pain that associated with this symptom is known as angina and if atheroma (Fatty material) breaks off and cause the blood clot, heart attack may occur.
There is a correlation between high blood lipid level and CHD and other heart diseases. Blood lipid level can be also called as cholesterol. High level of cholesterol is mainly because of diets concentrated in saturated fats and trans fats. Popular saturated fats are cheese and animal products and an example of trans fats are processed foods, cakes, cookies and fast foods. Saturated fats have same arrangements of molecules which make fats stack up easily. A routinely stacked saturated fats will not easily be broken down than unsaturated fats which are in irregular shapes. Irregular shapes, when stacked up have lots of spaces and increases the surface area allowing a faster breakdown of fat. Trans fats are hydrogenated oils and stay in semi-hard fats. On the other hand, unsaturated fats such as fish, seed, nuts, are all beneficial for the heart’s health.
However, the most important fact is that no matter what fat it is, if the consumption of fat is more than 37% of normal consumption of daily calories, the risk of getting a coronary heart disease increases. Also, it is recommended that an adult should not have more than 10% of its energy consumed in fat and for risk groups such as elders, consumption of fat is recommended to not exceed 7% of one's energy consumption.(Federation, 2016).

ReplyDelete-Background information concisely presented
-Use of statistics
EBI:
-You could mention other researches/experiment that supports the statistics (on the third paragraph)
Question:
-You've mentioned about the shape of the fat; is it the shape of the fat molecules or the way it is actually stacked in the arteries?
Q- First of all, the fat structure mentioned in this text meant the chemical structure of a fat molecule. Saturated fat molecules only have a single bond between each carbon, showing that there is a limited option with how the structure would look like. Therefore when they collide or goes together, the molecules will be stack up regularly with not much gap in between. However, unsaturated fats have more than one bond between carbon molecules which does not allow regular shape, making it difficult for fat molecules to be stacked up on each other.

ReplyDelete-Good explanation of the terms and clear layout.
-Concise writing
EBI:
-More researches and statistics may substantiate your claims.
Question:
In what ways are the unsaturated fat good for our health? What are the specific benefits that it puts on us?
Unsaturated fats decreases the risk of cardiovascular disease, and provide energy and vitamin. Unsaturated fat protects the heart and moreover, decrease the chance of some type of cancer.
