The correlation between high fat diet
and CHD.

Diet
is one of the biggest risk factors of CHD. Regarding it, there is a clear
research a high fat diet has a very strong correlation with coronary heart
diseases.
Fat is composed
of fatty acid and glycerol, and the type of a fatty acid in our body largely
changes the risk of causing CHD. There are two types of fatty acids: saturated
fatty acids and unsaturated fatty acids. Saturated fatty acid’s carbon atoms in
the hydrocarbon chain are bonded to the maximum number of hydrogen atoms and
saturated with hydrogen. Thereby, they have no double bonds between any of the
carbon atoms. Saturated fatty acids can be deposited inside the arteries, and
when they combine with cholesterol they cause atherosclerosis, which is a
disease that decreases the size of lumen and lead to hypertension. In addition,
research suggests that in countries where the diet is high in saturated fatty
acids, it is likely to increase chance of getting CHD. Despite the harmfulness
of saturated fatty acids, the Masai people have very low incidence of CHD. It
shows the importance of genetic factors in preventing diseases as their main
diet is based on milk and meat and the blood of goats and cows, which are rich
in saturated fatty acids.
Unsaturated fatty acid has one or more double
bonds in the hydrocarbon chain and they have two types of fatty acid in itself:
cis fatty acid and trans fatty acid. In contrast to saturated fatty acid, has
low incidence of causing CHD. People with Mediterranean style diet, which is
rich in unsaturated fatty acids rarely have CHD. Unlikely to saturated fatty
acids, they do not form plaques that block up the arteries, which are created
when fatty acids combine with cholesterol. However, it also causes CHD when
excessive amount of ‘trans’ fatty acids are ingested.
In conclusion,
generally the intake of saturated fatty acids is more likely to cause CHD compared
to unsaturated fatty acids. However, having unsaturated fatty acids may also
cause CHD if they take large proportion of a diet, since all fatty acids are
high in energy and able to cause obesity, which gives a strain to a heart.

What went well:
답글삭제- detailed explanation of the differences between saturated vs unsaturated fats
- specific examples such as 'Masai people'
Even better if:
- you included some examples of foods that contain high saturated fat / unsaturated fat/ trans-fatty acids
Questions:
-What is the difference between 'trans' fatty acids and other fatty acids?
- What about Masai people's genetics make them less prone to CHD?
not responding
삭제Q1-The difference between cis and trans is that the two H atoms are on the same side of the double bond (cis), compared to being on opposite sides (trans). This may not seem like much of a difference, but it affects the shapes of the molecules. In a cis configuration, the double bond creates a kink in the fatty acid.
삭제Q2
-could not find relevant information about it.

WWW: Concise and straight to the point. The implications of a high-fat diet summarised well. Could use of case studies (Masai and Mediterranean)
답글삭제EBI: Could refer to more than one sources. Stating some examples of food with high saturated fat/trans-fat/unsaturated fat content could have helped.
What can we replace trans-fat and saturated fats in our diet with?
What are the recommended amount of daily fat-intake? (in terms of food, not in grams. e.g. half a spoon of margarine)
-Q1
삭제•fruits, vegetables,
•whole grains,
•low-fat dairy products,
•poultry, fish and nuts,
•while limiting red meat and sugary foods and beverages.
-Q2
3 tablespoons of butter=36g of fat
You gave different examples of diet related to different cultures, which was great idea. They supported the idea that unsaturated fats are good for health. It was interesting that Masai people are less likely to gain CHD because of their genetic factor. I think for further research for CHD treatment, their genomics could be interesting to study.
답글삭제Coronary Artery Bypass Grafting
삭제CABG is a type of surgery in which arteries or veins from other areas in your body are used to bypass (that is, go around) your narrowed coronary arteries. CABG can improve blood flow to your heart, relieve chest pain, and possibly prevent a heart attack.
Cardiac Rehabilitation
Your doctor may prescribe cardiac rehabilitation (rehab) for angina or after CABG, angioplasty, or a heart attack. Nearly everyone who has coronary heart disease can benefit from cardiac rehab. Cardiac rehab is a medically supervised program that may help improve the health and well-being of people who have heart problems.

This is a good blog that is clear in its conclusion. You have explained the difference between saturated and unsaturated fats (you could have provided diagrams) and that one is believed to be more harmful than the other. I like that you have weaved the Masai and the Mediterranean diets into your article. Be careful, though, to draw such firm conclusions regarding diet and CHD and their causal relationships.
