Getting to the Heart of a Healthy Diet: Protein-Rich Foods
by Cynthia M. Johnson, MA
Protein can come from dairy products, meats, poultry, fish, nuts, legumes, and soy. Our bodies use them to:
You should choose your proteins with care. Some proteins (like red meat) are high in saturated fats. Eating too much of these fats may cause harm over time. There are many healthy forms of protein to choose from, though.
How Protein Choices Affect Your Health
Choose the Right Ones
Full fat dairy products (whole milk, yogurt, cheese), poultry skin, and many cuts of red meat are high in saturated fat. Saturated and trans fats raise bad (LDL) cholesterol and triglycerides, while lowering good (HDL) cholesterol. A high level of LDL in the blood raises the risk of coronary artery disease (CAD). This can lead to a heart attack. You can lower the risk by choosing lean meats and low- or non-fat dairy products and watching your serving sizes.
Plant based proteins like legumes are a good option. They have little saturated fat. You can add them to your meals so that you get enough protein without cholesterol risks.
Keep Arteries Healthy
Fish has less total fat and saturated fat than meat and poultry. Some fish are high in fat, but this fat is mostly omega-3 fatty acids—a type of polyunsaturated fat. Unsaturated fats, both mono and poly, are heart healthy. Omega-3s are thought to help keep arteries from hardening and to help keep blood from clotting and sticking to artery walls. Omega-3s may also help lower the risk of atherosclerosis and heart attacks.
Dark meat fish have higher amounts of omega-3 fatty acids. Keep in mind that fish oil pills have not been proven to have the same benefits.
Lower Blood Pressure
Keeping your blood pressure within normal limits will also help keep your heart healthy. The DASH diet (and the DASH-Sodium diet) have been shown to lower blood pressure in people with hypertension. It does this with low-fat dairy, lean meat, fish, poultry, eggs, and whole grains.
Learn About Serving Size
The American Heart Association says we should eat no more than 5.5 ounces of fish, shellfish, poultry (without skin), or trimmed lean meat per day. A serving is 3 ounces, which is about the size of a deck of cards. This is the same as:
You should also eat at least 2 servings (1 serving = 3 ounces) of fish per week to get the benefits of omega-3 fatty acids. Fish high in omega-3 fatty acids are:
Some fish have high mercury levels. If you plan on getting pregnant, are pregnant, or are a nursing mother, you should not eat shark, swordfish, tilefish and king mackerel. You can learn more about fish and mercury exposure at the http://www.epa.gov/mercury/advisories.htm website.
Shellfish can be higher in cholesterol than other kinds of fish, so try to limit how much you eat.
You can still eat meat but look at the type of meat you choose. Good choices are:
The healthiest ways to cook these lean meats are by:
Here are some healthy cooking tips:
Beans and peas are the mature forms of legumes. They are great sources of protein, dietary fiber, and can be counted as a vegetable or a protein serving. Here are some ways to add them:
Nuts are also plant protein, so toss a handful on vegetables, in stir fry, or in yogurt. They are good for you and the crunch adds extra texture.
In the Dairy Case
Dairy products are an added source of protein but can also have a lot of saturated fats. People who eat or drink dairy products should use low- or non-fat milk, yogurt, or cheese.
Make these changes slowly over time. Find healthy dairy products you like and try many types. Here are some easy ways to make small changes:
Take a few of these tips and start to work them into your daily menu. Healthy eating does not have to be boring or leave out all your favorite foods. Watch your serving sizes on foods that are higher in saturated fats and look for ways to swap them with healthier proteins or fats in your favorite meals. You may find the healthier versions taste just as good!
