Some low food or non-fat contain large amount of sugar to replace the fat contain of the food. How theses lead to increased fat in the body even though the item is not fat?

Effects of Dietary Fats on Lipoprotein Levels Cholesterol that is made by the liver or that enters the body from food does not dissolve in blood, so it is carried through the bloodstream by lipoproteins. Low-density lipoprotein (LDL) carries cholesterol to body tissues such as artery walls, where it can form deposits associated with cardiovascular disease. Thus, LDL is often called bad cholesterol. Highdensity lipoprotein (HDL) carries cholesterol away from tissues to the liver for disposal, so HDL is often called good cholesterol. In 1990, Ronald Mensink and Martijn Katan published a study that tested the effects of different dietary fats on blood lipoprotein levels. Their results are shown in Figure 2.23. Figure 2.23 Effect of diet on lipoprotein levels. Researchers placed 59 men and women on a diet in which 10 percent of their daily energy intake consisted of cis fatty acids, trans fatty acids, or saturated fats. Blood LDL and HDL levels were measured after three weeks on the diet; averaged results are shown in mg/dL (milligrams per deciliter of blood). All subjects were tested on each of the diets. The ratio of LDL to HDL is also shown. Source, Mensink RP, Katan MB, Effect of dietary trans fatty acids on high-density and low-density lipoprotein cholesterol levels in healthy subjects. NEJM 323(7):43945. An elevated risk of heart disease has been correlated with increasing LDL-to-HDL ratios. Rank the three diets according to their predicted effect on cardiovascular health.

Lipids are transported from the intestine to the liver by (a) chylomicrons (b) HDLs (c) LDLs (d) glycerol transporters (e) leptin

The preferred energy sources for the body are ________.

Why is it important for the diet to provide enough carbohydrates in order for the body to be able to make optimal use of dietary protein? Why might a high-protein diet not be the healthiest option for weight loss and weight loss maintenance?

Why are proteins especially important to children, pregnant women and people who are ill? What functions does protein perform in the body? Discuss why foods rich in complete protein are usually more expensive than foods containing incomplete proteins. Tell what amino acids are, and explain their importance. Which elements are proteins composed of? Explain/elaborate. Describe the process of digestion and absorption Explain why the body requirements fuel even during sleep. Describe metabolism. Why healthcare professional should practice the rules of good nutrition themselves From your personal experience, explain why certain foods are enjoyed more than other that are commonly available in the local area.

Why are people who consume many of their carbohydrates in the form of high-fructose corn syrup (HFCS) more apt to overeat than people who consume carbohydrates in the form of starches?   Explain how some starchy foods are healthier than others. What are three healthier starchy foods and why?

Starch and sugar have the same number of calories per gram. However, not all vegetables are equally calorie-dense. For example, a serving of boiled sweet potato provides about 1.2 calories per gram, while a serving of kale yields only 0.3 calories per gram. What could account for the difference in the calories your body obtains from these two foods?

A young man says that he is consuming much more protein in his diet than the recommended amount. He feels that he needs the extra amount just in case he wants to build more muscle mass in the near future. How would you respond to him? Group of answer choices It should be fine because the cells in his body will store the extra amino acids for future use. If he has excess calories in his diet, he may gain fat from converted protein. The extra protein will be used as fuel instead of carbohydrate. His body won't digest the extra protein and will eliminate the excess in feces. The excess amino acids can only be stored for up to 48 hours.

What are the essential amino acids and how does the body get them? Give an example of one of them and how it can be obtained. Briefly discuss why they are important to overall health and the consequences (health disorders) if they are missing from the diet. Why is a protein's structure important? What can happen if there are any changes? Provide an example and cite sources.
