Cutting back on saturated fats may reduce your risk of cardiovascular disease, but what replaces the saturated fat you're eating now is important, too.

The Academy of Nutrition and Dietetics and the United States Department of Agriculture suggest you keep your saturated fat intake to no more than 10 percent of daily calories (your total fat intake should supply around 20 to 35 percent of your calories).

 A person who needs 2,000 calories per day should consume no more than 22 grams of saturated fat. That's the amount of saturated fat found in four ounces of cheddar cheese, two cups of ice cream, or two large cheeseburgers. Some diets, such as the DASH diet, reduce that recommended amount even further -- to about seven percent of your caloric intake. But there doesn't appear to be much evidence that reducing your saturated fat intake that low -- or eliminating it all together -- would be any more or less beneficial.

If you regularly eat more than the recommended 10 percent of your calories from saturated fat, it's probably worth the effort to reduce your saturated fat intake to that level, especially if you have problems with cholesterol or high blood pressure. But that's only part of your dietary plan for reducing your cardiovascular risk -- you need to replace those saturated fats with good fats and reduce your total calorie intake if you are overweight or obese.

Eating too much saturated fat appears to elevate your levels of LDL cholesterol (the bad kind) and may lead to a pro-inflammatory state, both of which increase your risk of cardiovascular disease. Reducing the excess saturated fats should reduce those risks, but that may not happen if you replace the saturated fats with refined carbohydrates (white bread, pasta, sugar, high fructose corn syrup, etc).

If you replace the excess saturated fats with polyunsaturated fats or monounsaturated fatty acids (the good fats found in fish, nuts, seeds, legumes, canola and olive oils), you probably will reduce your risk of cardiovascular disease because the good fats reduce elevated LDL cholesterol levels and reduce inflammation.

Increasing your intake of polyunsaturated fats may also help to reduce elevated blood pressure; however, those good fats don't appear to have much of an affect on insulin sensitivity, which is a risk factor for both cardiovascular disease and diabetes.

Don't replace the excess saturated fats with artificial trans fats. They're often found in stick margarine, shortening, and foods made with partially hydrogenated oils. Trans fats appear to increase your risk of cardiovascular disease, probably even more than saturated fats. 

Your saturated (and total) fat intake isn't the only part of your diet that effects your heart health. Overweight and obesity are also risk factors for cardiovascular disease -- losing weight may also help to reduce high blood pressure and improve your cholesterol. It's important to eat a balanced diet that includes lean proteins, healthy fats, plenty of fruits and vegetables, whole grains, and low or non-fat dairy products.
