There is little doubt that choice of food is the best medicine not just for a sound and healthy heart but also for lowering blood cholesterol levels. This is best done by cutting back on saturated fats and limiting other cholesterol rich foods. About 80 percent of the body’s cholesterol is manufactured in the liver and 20 percent is derived from dietary sources. By itself the cholesterol found in food is safe but becomes a health concern when it gets oxidized as is seen in processed foods, cakes and cake mixes, cured and processed meats, dehydrated milk etc.
What is cholesterol?
Cholesterol is a wax like substance required by the body for many vital functions. Our nervous system, brain and the cell membranes require cholesterol for their normal functioning. It is also necessary for the manufacture of sex hormones and in the digestion of fats.
For its transportation in the blood it gets attached to lipoproteins, mainly high density lipoproteins or HDL and low density lipoproteins or LDL (lipids bound to proteins are called lipoproteins). The density is determined by the amount of protein that is bound to cholesterol. Approximately 20 to 25 percent of the blood lipoproteins are high density lipoproteins. They protect our body against cardiovascular diseases. They help remove cholesterol from the cells and arteries and carry it back to the liver where it is processed and the excess is excreted through the bile. About 60 percent of the blood lipoproteins are low density lipoproteins known as bad cholesterol. They carry cholesterol to the blood vessels and cells.
Food sources:
The most common sources of dietary cholesterol are animal products like eggs, red meat, dairy products and shell fish like prawns. Many people often ask if eggs are hazardous to health. The truth is that if you are leading a healthy and active lifestyle and if you have normal cholesterol levels, having moderate amounts of eggs (3 to 4 a week) will not cause much harm. Saturated animal fats and transfats found in processed foods are the real enemies.
Healthy digestion and consumption of healthy fibrous foods help to maintain a constant level of cholesterol in the blood stream. But this level can change or rise with age, a diet high in saturated fats and a poor lifestyle. A diet high in polyunsaturated fats and fiber helps to lower levels of blood cholesterol while a diet high in meats, cream, full cream dairy products and white flour tend to increase the amount of cholesterol in the blood thereby increasing the risk of heart diseases. Cholesterol becomes an issue when an excess of low density lipoproteins are present in the blood. This accelerates plaque formation on the arterial walls. These fat deposits on the lining of the arteries cause the vessels to become less elastic leading to a condition known as Atherosclerosis. These plaques restrict the flow of blood through the arteries and cause clots to be formed. When this occurs in any of the major blood vessels of the heart or brain it causes a stroke or serious coronary problems.
Experts are of the opinion that diet alone does not create a high risk of heart diseases. Smoking habits, heredity, activity level, obesity and life style parameters play an equally important role. A reading above 200mg/dl is considered borderline and above 250mg/dl is considered high risk for developing heart diseases.
A common question that is often asked is how to increase the HDL (good cholesterol) and how to decrease the LDL (bad cholesterol).
This can be done by increasing your intake of fruits, vegetables like greens, broccoli, capsicums and other high fibrous vegetables. It’s also advised to increase ones consumption of oils that have beneficial effects on your health. Oils high in omega-3 fats found in soy beans, walnuts, fish oils, flax seed oil and olive oil are very useful in raising the HDL levels. Restricting your intake of foods like saturated fats from red meats, cheese, cream, high fat milk, junk foods and processed foods will go a long way in reducing your LDL or the bad cholesterol.
