Question
1. Plaque Formation in Arteries: High levels of LDL cholesterol in the bloodstream can lead to formation of plaques" in the arteries. What are the potential health consequences of coronary arteries being clogged by "plaques"? Name some specific foods that might lead to increased LDL cholesterol in the bloodstream What do these foods contain that could cause this? 2.

Nutrition Facts Serving Size 1az Servings per container4 %Daily Value : How many grams of total fat would a person consume10 Total F if he/she ate the whole container? How many calories are from fat per serving? " Calculate the percentage of the total calories per serving that come from total fat? Pr Based on a 2,000 calorie diet, what percent of the USDA's percent daily value for total fat would be consumed per serving? Calculate the percent if the whole container was consumed? .
Explanation / Answer
1] * Plaque formation in the inside of the arteries narrows down their lumen, thus making the blood flow slow and requiring more effort by the heart. If left unchecked, the plaque might completely block the arterial passage, stopping the blood flow to that part of the body where the artery goes. This is a life-threatening situation.
Plaque is formed when there is an excess of fats, cholesterol, calcium and other substances in the blood.
Coronary artery provides blood to the heart. If there is plaque formation in the inside of this artery the blood flow to the cardiac muscles will be obstructed and the cardiac muscles will not get enough oxygen. This will result in a heart attack that can prove fatal for the person.
* LDL or low-density lipoprotein is one of the five major groups of lipoproteins. It is considered bad because it leads to a build-up of cholesterol in the arteries
Saturated fats are mostly found in animal foods like beef, lamb, poultry, and pork. Milk and milk products such as butter, cream, cheese etc are other sources of animal fats. Plant products like coconut and coconut oil, palm and palm kernel oil, chips and other fatty food items are also rich in saturated fats and increase the LDL levels in the blood.
* The above-mentioned food items contain a lot of saturated fats and cholesterol which raises the LDL level in the blood.
2] Total fat = 11g
Saturated fat = 3g
Trans fat = 2g
* 16g
* Calories = 155
* % of total fat = 11/16 * 100
= 68.75%
Trans Fat --
Trans fat or trans fatty acids are made up of unsaturated fatty acids. These are a type of unsaturated fats that occur in small amounts in nature but can be produced commercially on a large scale from vegetable oils.
Saturated fats have no double bonds between the carbon atoms but trans fats have one or more double bonds between their carbon atoms. To make it saturated, it will have to be hydrogenated to remove the double bonds.
