What else can I help you with?
Would impaired fat absorption in the intestines interfere with vitamin A absorption?
Yes.
Do you need dietary cholesterol?
No. Your liver is capable of producing cholesterol and hormones from saturated fat. Vegans do not consume dietary cholesterol, yet can be perfectly healthy with an otherwise balanced diet.
What group of food is cholesterol?
Cholesterol is not a food it is a waxy steroid of fat that is produced in the liver or intestines of mammals.
Infants depend on dietary fat and cholesterol for formation of what?
Brain and nerve tissue
Lymphatic vessels serve to absorb fat molecules from the?
Lymphatic vessels serve to absorb fat molecules from the intestines, transporting them through the lymphatic system to the bloodstream. This process allows for the efficient absorption and distribution of dietary fats within the body for energy production and storage.
What is a characteristic of the blood cholesterol level?
It can be lowered more effectively by reducing dietary intake of saturated fat than of cholesterol
What are the largest lipoproteins ranging in diameter up to 0.5 produced by intestinal epithelial cells from the fats in food?
The largest lipoproteins produced by intestinal epithelial cells from dietary fats are chylomicrons. These lipoproteins can range in diameter from 75 to 1,200 nanometers, making them the largest class of lipoproteins. Chylomicrons are primarily responsible for transporting dietary triglycerides, cholesterol, and fat-soluble vitamins from the intestines to other tissues in the body. They are formed in the enterocytes of the intestinal lining after the absorption of dietary lipids.
Where is the predominant site of dietary fat?
The small intestine is the main site of dietary fat digestion. The small intestine is part of the gastrointestinal tract. The majority of fat absorption occurs in the ileum of the small intestines Fats (or lipids) are digested using the enzyme lipase (made in the pancreas and small intestine) throughout the small intestine. The products of this reaction are glycerol and 3x fatty acid molecules.
What is the best description of a daily low saturated fat and low cholesterol eating plan?
Less than 7 percent of calories from saturated fat and less than 200 mg of dietary cholesterol.
Is cholesterol present in oils?
Generally not; oils are liquid lipids, and cholesterol is an animal fat. Most dietary oils are vegetable extracts, and hence have no cholesteral whatsoever.
What three substances can raise the blood cholesterol level and what is this a concern?
Saturated fats, dietary cholesterol, and trans fat and its a concern because you could get a heart attack
Why is cholesterol vital for health?
It is used in cell membranes and is the substrate for making sterol hormones and vitamin D. Cholesterol is made in then liver and humans have no dietary requiment for cholesterol. Cholesterol is converted into bile acids. Bile acids act as a solute to cholesterol in the gallbaldder, preventing gallstone formation, help the absorption of fat soluble vitamins and emulsify fats so they are avalible to pancreatic lipase. Bile acid production is the only method for excreating excess cholesterol.
