Step #4: Slash your intake of saturated fat.

Butter. Sour cream. Mayo. These foods—as well as fatty cuts of meats—are high in the saturated fats that elevate "bad" LDL cholesterol, leading to plaque buildup in arteries. Limit saturated fats to 5 percent or less of your total calories (divide your weight by 12 to get the daily total limit in grams). For example, try replacing butter with vegetable-based oils, particularly olive and canola oil, both of which contain good amounts of heart-healthy monounsaturated fats, and by swapping in lean poultry, fish and beans for higher-fat meats.

Step #5: Junk the junk food.

Many packaged snacks, crackers, bakery goods and some margarines contain artificial trans fats (a.k.a. hydrogenated oils), which increase "bad" LDL even more than saturated fats, according to recent research by Walter Willett, M.D., at the Harvard School of Public Health. In a 2003 interview with EatingWell, Willett blamed trans fats for millions of unnecessary premature deaths from heart disease. Read labels carefully: if a package claims "zero trans fat," the amount per serving may be less than 0.5 g and could have been rounded down to zero. The only way to be sure you’re getting a product without trans fats is to avoid products that include "hydrogenated oil." Better yet, stock up on nutrient-rich vegetables, fruit and nuts.

Step #6: Fill up on fiber.

Various studies link a high-fiber diet with a lower risk of heart disease. In a Harvard study of female health professionals, people who ate a high-fiber diet had a 40 percent lower risk of heart disease than those who ate a low-fiber diet.

Aim to include plenty of foods that are rich in soluble fiber, which, studies show, can help lower "bad" LDL. Soluble fiber binds bile acid, a key component in fat digestion that our bodies make from cholesterol. We can’t digest fiber, so when bile acids are bound to it, they get ushered out of the body as waste. This causes the body to convert more cholesterol into bile acids, which ultimately has the effect of lowering circulating cholesterol levels. Foods high in soluble fiber include oatmeal, barley, beans, okra and eggplant, and citrus fruit, such as oranges.

Step #7: Replace refined grains with whole ones.

Eating too many refined carbohydrates (e.g., white bread, pastries, white pasta) fuels the body’s ability to make triglycerides. What’s more, processed grains are quickly converted to glucose, which raises blood glucose levels and may predispose one to developing type 2 diabetes, a risk factor for developing heart disease. Choose whole grains, such as brown rice, wheat berries and quinoa and whole-wheat pastas, which contain more fiber (which slows down the conversion of starches to glucose) and healthful fats than processed grains.

Step #8: Go fish.

Consuming two or more servings of fish per week is associated with a 30 percent lower risk of developing coronary heart disease over the long term, studies show. Fish contain omega-3 fats, which lower levels of triglycerides in the blood that may contribute to blood clotting. Omega-3s also lower blood pressure slightly and can help prevent irregular heart rhythms. (Flaxseed oil, canola oil and walnuts also contain omega-3 fats.)liuxuepaper.com
