Heart disease is still the nation's number-one killer. Exactly what keeps your heart healthy is still a bit controversial, but what we do know is that being physically active, eating fruits and vegetables, reducing certain types of saturated fats, and increasing "good" fats all help. Here are a few swaps that could help you have a healthier heart.1. Snack on pistachios.
Research in the Journal of the American College of Nutrition has shown that a four-week pistachio diet containing moderate amounts of heart-healthy fat decreases risk factors for heart disease with no weight gain. Another study, done at Penn State, compared two groups, one following a cholesterol-lowering diet and another that added pistachios to the same diet. Researchers concluded that eating either 1.5 or 3 ounces of pistachios daily reduced the risk of cardiovascular disease by significantly reducing LDL (bad) cholesterol levels. In addition, the higher daily dose reduced lipoprotein ratios.
While pistachios are packed with fiber, vitamins, and potassium, a mere half-ounce of pistachios (24 nuts) has approximately 85 calories. So, eat them sparingly, account for them in your daily caloric budget, or use them to replace high-calorie, high-fat foods like chips, which have about 150 calories per ounce.
A diet high in whole-grain foods is associated with a significantly lower risk of cardiovascular disease, including heart disease and stroke, according to an analysis by researchers at Wake Forest University School of Medicine. (Read more about whole grains at www.dietdetective.com/content/view/1141/2/.)
Consuming 2.5 servings of whole grains daily is associated with a 21 percent lower risk of cardiovascular disease compared with consuming 0.2 servings. These results were published in the journal Nutrition, Metabolism & Cardiovascular Diseases. Make sure to look for "100 percent whole grain" on labels or for specific types of whole-grain flour, such as "whole wheat," as the first ingredient.
Use Glad SimplyCooking Microwave Steaming Bags: Put your washed vegetables into the bag, seal it, place in the microwave, and minutes later you have steamed vegetables without adding water or oil. Vegetables are high in fiber, and a diet rich in fiber can help lower blood cholesterol and reduce your risk of heart disease.
You don't have to switch all at once. Go from whole milk to 2 percent, then 1 percent, and before you know it you'll be a skim milk aficionado. One cup of whole milk has almost 5 grams of saturated fat, whereas skim milk has only 0.125 grams, not to mention the calorie savings (146 calories per cup for whole milk vs. 83 calories for skim).
If you're looking to save calories and saturated fat, using a margarine spray such as I Can't Believe It's Not Butter or Smart Balance is a good way to start (10 calories per 10 sprays). Butter has 100 calories per tablespoon and contains more than 7 grams of saturated fat.
People who significantly cut back on salt could reduce their chances of developing cardiovascular disease by 25 percent, according to a report in the British Medical Journal. Furthermore, researchers found that lower salt intake could cut the risk of death from cardiovascular disease by up to 20 percent.
By using garlic instead of salt, you not only get the benefit of lower blood pressure, you also get the health perks of garlic, such as fighting cancer and possibly reducing the risk of cardiovascular disease by lowering total LDL (bad) cholesterol without affecting HDL (good) cholesterol.
The Healthy Heart Handbook for Women, published by the National Heart, Lung, and Blood Institute (NHLBI), includes statistics, quizzes, and charts. It's free and a great resource.
Instead of that big, thick steak, which has saturated fat and lots of calories, try wild salmon, which has high concentrations of omega-3's. One of the key benefits of omega-3 fatty acids is that they significantly reduce the risk for sudden death from cardiac arrhythmias and deaths from many causes in patients with coronary heart disease.
A study in the Journal of Epidemiology and Community Health suggests that even low levels of weekly exercise drive down blood pressure and boost overall fitness. And while current recommendations are to get 30 minutes of moderately strenuous exercise on at least five days of the week, even a few minutes a day is better than nothing.
Avoiding certain saturated fats can be one of the keys to heart health (being a healthy weight and eating "right" also matter), so switching your current oil (e.g., palm or corn oil) to olive oil, which has some "good" fat, can help. The Food and Drug Administration actually lets olive oil manufacturers make a health claim stating that 2 tablespoons of olive oil daily "may reduce the risk of coronary heart disease."
However, just because olive oil is heart healthy doesn't mean you can use it with impunity -- it still has 120 calories per tablespoon. So use it to replace existing fat in your diet. And use it sparingly, or try a cooking mister or spray.
