******New answers please*****

The purpose of this assignment is to understand processes within organ systems and organisms that control the body to maintain homeostasis.

Apply critical thinking to answer the following:

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 Labels: Analyze the nutrition label attached and answer the following questions:

• How much total fat, saturated fat and trans fat does this product contain per serving?

• How many grams of total fat would a person consume 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.

• Based on a 2,000 calorie diet, what percent of the percent daily value for total fat would be consumed per serving? Calculate the percent if the whole container was consumed.

• Based on what you know about trans fats, do you think there are hydrogenated oils in this product? Explain.

Answer 1

Q 1.Plaque Formation in Arteries: High levels of LDL cholesterol in the bloodstream can lead to formation of “plaques” in the arteries.

• The potential health consequences of coronary arteries being clogged by plaques.

Answer :- The coronary arteries supply blood, oxygen and nutrients to your heart.

1. A buildup of plaque can narrow these arteries, decreasing blood flow to your heart.
2. Eventually, the reduced blood flow
3. may cause chest pain (angina), shortness of breath, or other coronary artery disease signs and symptoms.
4. A complete blockage can cause a heart attack.

• Name some specific foods that might lead to increased LDL cholesterol in the bloodstream.

Answer :-

1. fatty cuts of meat.
2. full fat dairy products such as milk, cream, cheese and yoghurt.
3. deep fried fast foods.
4. processed foods such as biscuits and pastries.
5. takeaway foods such as hamburgers and pizza.
6. coconut oil.
7. butter.


• What do these foods contain that could cause this?

Answer :-

There are two types of cholesterol.

These are based on the type of protein that transports it through the bloodstream:

Low-density lipoproteins deposit one type of cholesterol throughout the body. As this kind of cholesterol is likely to build up, people often refer to it as “bad” cholesterol.

High-density lipoproteins (HDL) collect bad cholesterol from the arteries and bring it back to the liver for disposal. For this reason, people refer to HDL cholesterol as “good” cholesterol.

The bloodstream absorbs swallowed cholesterol poorly and has little effect on cholesterol levels after several hours. It may absorb some of this cholesterol, however, and it might reach the arteries. Limiting high-cholesterol foods might still be beneficial.

Foods that contain cholesterol and may be best avoided include:

red meat

sausage

bacon

organ meats, such as kidney and liver

Foods to include

It is important to note that a completely fat-free diet can also be harmful because it would deplete the levels of good carbohydrates, impair normal nerve and brain function, and possibly increase inflammation.

Choosing healthful fats can help lower bad cholesterol levels while maintaining and in some cases increasing good cholesterol levels.


Q 2. Nutrition Labels: Analyze the nutrition label attached and answer the following questions:

• How much total fat, saturated fat and trans fat does this product contain per serving?

Answer :-eating a diet with too much saturated fat and cholesterol. ... know how much “bad” fat is in foods. ... ments that contain 0.5g or more of trans fat per serving will ... breads, followed by animal products and margarine.


• How many grams of total fat would a person consume if he/she ate the whole container?


Answer :-In a healthy diet, about 30 percent of total daily calories should come from fat. This means eating about 50 to 80 grams of fat each day. Fat gives the body energy, too, but the body changes only about 10 percent of fat into glucose.

• How many calories are from fat per serving?

Answer :-To get this percentage, divide calories from fat by total calories (this information appears on the food label) and then multiply by 100. For example, if a 300-calorie food has 60 calories from fat, you divide 60 by 300 and then multiply by 100. That food has 20% of its calories from fat.

• Calculate the percentage of the total calories per serving that come from total fat.

Answer :-Multiply the grams of saturated fat by 9 = (xx) the number of saturated fat calories in the food item. b. Divide (xx) the number of saturated fat calories in the food item by the total number of calories in the food item = % of saturated fat. 1) Fat – 3 x 9 = 27 fat calories; 27/90 = 30% total fat.
