Relative to coronary heart disease, why is there a major focus on dietary fat?
According to current dietary recommendations, trans fat intake should be limited. How is this best accomplished?
Group of answer choices
Select foods containing manufactured rather than naturally occurring trans fats.
Read labels to select foods that say “polyunsaturated fatty acid free.”
Choose foods with <10% of calories from saturated fat per serving and no hydrogenated oils in the ingredients list.
Use fat replacers, such as olestra, which provide the same nutrient content as regular fats without being saturated.
Avoid all processed foods such as bakery items, packaged cookies, and store-bought bread.
Which of the following is not true for reducing the risk of heart attacks?
if saturated fat in the diet is replaced with unsaturated fats, the risk for heart disease decreases
replacing total fat or saturated fats with carbohydrates is not associated with reduced risk of heart attacks
if saturated fat in the diet is replaced with refined carbohydrates, risk for heart disease increases
saturated fats in the diet should be replaced with polyunsaturated and monounsaturated fats
if saturated fat in the diet is replaced with refined carbohydrates, risk for heart disease decreases

- High blood-cholesterol levels are dangerous because of their correlation with atherosclerosis and consequent heart attacks and strokes. Is it possible to eliminate all cholesterol from the bloodstream by having a diet that includes no cholesterol? Is it desirable to have no cholesterol at all in your body? Explain your answer.arrow_forwardEffects 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. In which group was the level of LDL (bad cholesterol) highest?arrow_forwardEffects 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.

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.

- Unhealthy saturated fats are often animal-based, while the more healthy unsaturatedfats are often plant-based. What is the difference between saturated and unsaturated fats inwhole cow’s milk vs. soy milk according to the image?arrow_forwardCurrent dietary recommendations to reduce the risk of coronary heart disease include all of the following EXCEPT O Eliminate all dietary cholesterol from your diet, such as that found in egg yolk, because it is the main cause of heart disease. O Consume more monounsaturated and polyunsaturated fats such as those found in olive oil, fish, nuts, and avocados instead of saturated fats found in red meats. O Increase consumption of oats, legumes, and soy products that may help lower blood cholesterol levels. O Try to eliminate trans-fats from your diet completely.arrow_forwardIdentify ALL of the following which are TRUE regarding cholesterol and disease: if an artery leading to the heart is blocked, a heart attack could result O Artery inflammation can increase the risk of clots and thromboses; this could lead to arterial blockage (reduced blood flow in an artery) blood vessel inflammation can become self-perpetuating; where inflammation occurs, it becomes more likely that inflammation will continue, especially when blood LDL are high and HDL are low An arterial plaque can increase the chance of developing hypertension exercise has no effect on blood cholesterol dietary artificial trans fats seem to increase LDL and decrease HDL more than both dietary saturated fats and dietary cholesterol in most people (that is, trans fats are worse than sat fats and cholesterol) if a product lists "partially hydrogenated" oil as an ingredient, it contains some trans fat even if it is less than .5 g per serving. hypertension can put extra strain on the heart and increase…arrow_forward
- Diamond and her family enjoy eating foods that are closer to nature. They have an indoor herb garden that they maintain year-round. To celebrate her love for plants and herbs, Diamond created a podcast encouraging her community to eat more plant-based foods. Diamond recently declared herself as a lacto-ovo vegetarian since she enjoys dairy products and eggs. Diamond is very active and likes the convenience of boiled eggs and nuts as protein sources. Do you think that Diamond can reasonably get enough protein from her new diet, considering she stands 5 feet 11 inches tall and weighs 155 pounds?arrow_forwardDiamond and her family enjoy eating foods that are closer to nature.

- Why is hydrogenation so appealing that companies will continue to include hydrogenated oils in their products despite the social stigma that trans fats have acquired? If hydrogenation is supposed to produce saturated fats, then why do its byproducts include these undesirable trans unsaturated fats? Eliminating fat from the diet to decrease health risks, yet many nutrition arguments are being made about the importance and value of fats in a balanced diet. Discuss these points and how you feel fats can be incorporated into a healthy diet, if at all.arrow_forwardThe Dietary Guidelines for Americans make all of the following suggestions except: 1) choose diets that emphasize dark green, red and orange vegetables. 2) include beans and nuts. 3) choose foods low in saturated and trans fats. 4) choose diets that emphasize more refined and enriched grain products. 5) choose a diet low in added sugars, solid fats and sodium.arrow_forwardEgg yolks contain a high amount of cholesterol, but they also contain a high amount of lecithin.
