OMEGA-3 FATTY ACIDS

More Americans die each year from heart disease than any other disease. As we age, our risk of heart disease increases, especially after menopause for women. Several other factors are attributed to our risk as well. Some, such as genetics, are out of our control. However, many risk factors have been proved to increase our risk of heart disease. These factors include smoking, high blood cholesterol levels and hypertension. Many other factors are likely to increase our risk of heart disease, including diabetes, physical inactivity, low HDL (‘good’) cholesterol levels and obesity. Several dietary links are being examined as to determine their role in either promoting or reducing cardiovascular risk. Omega-3 fatty acids have been shown to reduce risk of cardiovascular disease.

Saturated Fatty Acids

Saturated fatty acids are fatty acids with no double bonds (see fatty acids for a visual image of a saturated fatty acid). They are not essential for human metabolic processes but provide energy or are deposited in fat depots.

Fiber

Current estimates suggest 59,700,000 Americans have one or more types of cardiovascular disease. By far, cardiovascular disease has been the number one killer in the United States since 1900. An American dies on average every 33 seconds from cardiovascular disease. Understanding the relationship of our lifestyle and dietary factors to our risk of cardiovascular disease is vital to protecting ourselves as much as possible. Several factors have shown to increase the risk of cardiovascular disease. Low dietary fiber intakes are one such factor.

Trans fatty acids
Excess dietary fat is often times the culprit of many diseases. Excess dietary fat is associated with an increased risk of developing cardiovascular disease. However, not all fat is created equal. Much research has shown saturated fat to be the most undesirable form of fat. Monounsaturated fats appear to have heart healthy benefits. However, another important variety of fat to consider is trans fatty acids. Trans fatty acids have been shown to have adverse affects similar to saturated fat. Since consumption of trans fatty acids in the typical American diet is increasing, we must give attention to this health risk.

Cholesterol is carried in the blood in the form of lipoproteins, which are dynamic particles with protein on the outside and an inner core of cholesterol and fats. Both lipoproteins and apolipoproteins are strong predictors of CHD risk. The term dyslipidemia applies to a high blood level of total cholesterol (TC), as well as other abnormalities in blood lipid levels including an elevated low density lipoprotein cholesterol level (LDL-C), a decreased high density lipoprotein cholesterol (HDL-C) level and an elevated very-low-density lipoprotein (VLDL) and triglyceride level.
