|
Obesity is known to be a dietary factors in causing
Cancer Cardiovascular disease Type 2 diabetes Also obesity is linked to Gallstones Osteoarthritis High blood pressure or hypertension |
|
|
What is atherosclerosis
|
It is deposition of fatty substance is in the walls of the coronary arteries deposition in the coronary artery walls narrow size of the lumen this restricts blood flow to the heart muscle which may cause oxygen starvation
|
|
|
How does too much salt in your diet increase the risk of getting chd
|
Excess salt in your diet will decrease the water potential of your blood as result more water is held in your blood and blood pressure increases this leads hypertension. hypertension can damage the inner lining of the arteries which is one of the early steps in the process of atherosclerosis.

|
How does too much fat or lipids in the diet increase the risk of chd
|
Saturated fats found in animal fats tend to be more harmful than unsaturated fats found in plants
|
|
|
How does cholesterol in the diet increase the risk of chd
|
Cholesterol is not a triglyceride but have similar properties too much cholesterol in the blood is harmful high blood cholesterol concentration has been linked to a lot of deaths from coronary heart disease the concentration of cholesterol in the blood should be maintained below 5.2 mmol dm ^ -3
|
|
|
Why is cholesterol in the blood
|
Restaurant is essential to the normal functioning of the body it is found in cell membranes and skin.
|
|
|
what are lipo proteins
|
Lipoproteins in the blood are cholesterol in a form that will mix with water views are tiny balls of fat combine with proteins and there are two types of lipo proteins they are
high density lipoproteins Low density lipoprotein |
|
|
what are high density lipoproteins
|
Hdl are produced by unsaturated fats cholesterol and proteins they carry cholesterol from the body back to the liver to make bile hdlove are associated with reducing blood cholesterol levels therefore they reduce the depositions in the artery walls and they even help remove fats from artery walls.
|
|
|
What are low density lipoproteins
|
Ldls are a combination of saturated fats cholesterol and protease they carry cholesterol from the liver to the body tissues and too much fat is consumed in the diet then ldls in the blood will rise.
|
|
|
How do we control the levels of ldl and hdl in our diet
|
We can't eat lycopodium but we are diets have a significant effect upon a lipo proteins concentration in a blood eating a lot of saturated fat increase the concentration of ldls in our blood
Eating a low fat diet for reduced the overall concentration of lipo proteins Eating a high proportion of unsaturated fats increase the proportion of hdl in the blood Eating polyunsaturated fats help reduce the concentrations of ldl in the blood Eating monounsaturated fats would help to reduce the concentration of ldl in the blood |
