A Balanced Diet Part VII: Fats, Oils and Sweets

We all love dessert, but we also probably eat more than we should.  Consuming fats is an important part of our diet, but the wrong amounts of the wrong types can lead to weight gain, obesity, and increased risk of heart disease.  Because of these risks, we want to consume the least amount of food in this group.  Oils and fats are different, and since sweets have lots of fats, they are included in this group.  The oils most people are familiar with include canola oil, olive oil, and corn oil, while the fats are butter, chicken fat, and stick margarine.  Sugary sweets include brownies, cookies, cakes, and soft drinks.

Oils contain essential nutrients, are liquid at room temperature, and are needed to help our bodies function.  Fats are also an essential part of the human diet, but unlike oils, they are solid at room temperature.  Fats come with more trans- or saturated fat than oils do, and it is important to be careful how much you eat.  Unsaturated fats (HDL) are healthy, but saturated fats (LDL) can lead to the weight gain, obesity and risk of heart disease mentioned earlier.  While oils and fats both contain a mixture of saturated and unsaturated fatty acids, solid fats contain more saturated and trans-fats than oils.  Saturated fats are mainly found in animal products and should make up less than 10% of daily caloric intake.  Fats as a whole should not account for more than 30% of daily caloric intake.  Respecting this guideline is important because one gram of fat contains nine calories, which is more than twice that of protein and carbohydrates (four grams each) and makes it very easy to consume too much fat.  Sugars, even though they also have four calories per gram, bring mostly empty calories into our diets.

The food we eat fulfills most of our daily needs for oil through things such as nuts, cooking oil and salad dressing.  Even though we get oils from our food, remember that they do contain calories.  That makes checking labels and looking for options with no trans-fat and little to no saturated fat a big part of maintaining a healthy diet.  By using oils sparingly when cooking, cutting down on sugary after dinner treats and ceasing to drink sodas, you can control your intake of bad fats and sugars, while helping lower your risk for weight gain and heart disease.

A Balanced Diet Part VI: Milk, Yogurt and Cheese

We all love ice cream, milkshakes, and cheese trays, but making the right dairy choices in the dairy group, as well as all other food groups, is the key to maintaining a healthy diet.  The dairy group includes cheese, milk, yogurt, soymilk, and all the products made from them.  Lots of important nutrients come from dairy products, but it is possible to have too much of a good thing when it comes to things like cheese and ice cream.  Getting the proper amount of dairy products may reduce the risk of osteoporosis, and has been shown to improve bone health.  Calcium is especially important during childhood, as bones are growing and mass is accruing.  Good dairy intake is also a source of reduced risk for cardiovascular diseases and type 2 diabetes, as well as having been shown to lower blood pressure in adults.

Milk, yogurt and cheese all contain calcium, protein, potassium, and vitamin D.  Calcium serves as the building blocks for bones and teeth by helping them grow and maintain their mass.  Vitamin D works with the body to help it absorb calcium, reduce inflammation and boost immune function.  Dairy protein, just like the protein found in the Meat Group, helps build muscle and provide energy, while potassium can help maintain healthy blood pressure.

Choosing low-fat or fat-free dairy products is best because they contain little to no solid, or saturated, fat.  Saturated fats contain high levels of LDL (low-density lipids), bad cholesterol, and a diet high in LDL can increase risk for coronary heart disease.  Whole milk and many cheeses are high in saturated fats, so limiting dairy choices to low- and non-fat options is important when trying to control your intake or empty calories.

Even when consuming low- and non-fat dairy products, following the suggested guidelines for daily servings, and adjusting based on increased activity, is part of maintaining a balanced diet.  For the Dairy Group, three servings are recommended each day, though dairy products should not exceed 30% of caloric intake per day.  One serving is considered one cup of milk [fat-free (skim) or low-fat (1% or 2%)], one eight ounce container of yogurt, 1½ ounces of hard cheese, one third cup of shredded cheese (cheddar), two ounces of processed cheese (American), one cup of pudding made with milk, one cup of frozen yogurt, 1½ cups ice cream or one cup of calcium-fortified soymilk.

It can be hard to make good choices, but here are some ways to make it simple.  Order lattes and cappuccinos with fat-free milk, add fat-free or low-fat milk to oatmeal instead of water, use yogurt as a dip for fruits and vegetables, and use low-fat cheese to top casseroles and soups.  Be sure to avoid raw (unpasteurized) milk, chill perishable foods promptly and keep separate raw and cooked foods.  Follow these guidelines and you’ll be sure to make good Dairy Group choices to help you maintain your balanced and healthy diet.

A Balanced Diet Part V: Meat, Poultry, Fish, Beans, Eggs and Nuts

Is the name of this group enough to get you interested?  With so many choices out there for protein sources, it can be challenging to know what the best ones are.  Foods in this group include beef, pork, venison, chicken, duck, flounder, tuna, lima beans, pinto beans, shellfish, peanut butter, and almonds.  Wow.  Not only does this group contain a wide variety of choices, it provides a long list of healthy body benefits.

Nutrients pulled from the protein group range from, as expected, protein, which is also found in fats and carbohydrates and provides calories for energy, to iron, which carries oxygen to the blood.  The antioxidant Vitamin E, zinc that helps the immune system function and magnesium for building bones are all found in meat, poultry and fish.  Elements in each of the foods in this group are also the building blocks for muscles, cartilage, skin, blood, integral enzymes and hormones.  Omega-3 fatty acids are present in seafood, and 8 ounces of fish per week may help prevent heart disease.  The risk of potential heavy metal poisoning from consuming certain fish species frequently is greatly outweighed by the benefits of omega-3s.  Nuts and seeds are a high calorie food great for snacks.  They also aid in reducing the risk of heart disease, though it is important to limit sodium intake by eating unsalted nuts.

Making the right meat, poultry and fish choices is hard, so here are some tips for getting the best you can:  Cholesterol is only found in animal source foods, and fatty meats contains lots of low density lipids (LDL), or bad cholesterol.  LDL is a root cause of coronary heart disease risk, so choose lean meats and cut excess fat off before cooking.  Eliminate excess cooked fat by draining during cooking, limiting breading, and using low fat sauces and gravies.  Vary your lean meat choices, while mixing in fish at least twice per week.  Skip the egg yolks, take them out of hard boiled eggs, separate them from cooked eggs or purchase premade egg whites since yolks contain plenty of LDL as well.  Eating lots of fat usually leads to an excess consumption of calories, and that means extra time at the gym to maintain or lose weight.  Be sure to read labels, and know processed meats often contain excess sodium and more fat than raw foods.

After you’ve picked the right foods, you should consume between 5 and 6 ounce equivalents per day in the protein group, and the amount should be increased in proportion with activity.  One ounce of meat, poultry or fish, one egg, one tablespoon of peanut butter, ½ ounce of nuts, ¼ cup cooked beans or ¼ cup cooked peas all count as one ounce equivalents.  When preparing raw protein group foods, be sure to separate raw food from what is already cooked.  Thawing meats, poultry and seafood should occur quickly, in a microwave or by submerging in cool water.  After thawing raw meat or poultry, it should not be washed, but any and all cooking utensils, cutting boards and pans should be cleaned with hot, soapy water between each food item it touches.  A great way to avoid consuming raw or undercooked meats, poultry and eggs, which can carry salmonella, E. coli and other nasty food borne illnesses, is to use a meat thermometer.  After cooking, protein group foods should be chilled or frozen promptly.

Vegetarians can get enough protein from non-meat, poultry or seafood choices in this group, but vegetarian diet will be addressed entirely in its own segment.  For more information on the Meat, Poultry, Fish, Eggs, Nuts and Seeds Group, visit http://www.choosemyplate.gov/food-groups/protein-foods.html.  Be sure to stay tuned for next week’s segment, A Balanced Diet Part VI: Milk, Yogurt and Cheese!

A Balanced Diet Part IV: Fruits

Whole grains and vegetables for every meal are great, but here’s a good way to add even more variety to your diet: eat fruit!  Fruit is colorful, flavorful and good for you.  The Fruit group is made up of berries (blueberry, raspberry, strawberry), citrus (orange, grapefruit, tangerine), melons (watermelon, honeydew, cantaloupe), tropical (banana, mango, pineapple), stones (cherry, peach, plum) and others (apple, grape, pear).  Eating a healthy amount of fruit per day can reduce the risk of heart disease, help protect against some types of cancer, reduce the risk of diabetes and obesity, lower blood pressure and decrease bone loss.  It is also low in fat and sodium while rich in potassium, dietary fiber, Vitamin C (helping with growth, healing wounds, maintains healthy teeth and gums), folic acid (reduces risk of birth defects and aids in formation of red blood cells), and Vitamin A (an antioxidant).

Fruit is classified as whole or cut fruit or 100% fruit juice that arrives on your plate (or in your glass) fresh, canned, frozen, dried or pureed.  A serving of fruit can be one large apple, one cup of natural applesauce, one cup of 100% fruit juice, one cup of grapes, one large orange, or eight big strawberries.  Two to four servings per day are recommended, the equivalent of one to three cups.  Following these recommendations allow the dietary fiber content of fruit to provide fullness without the high caloric content of many other diet choices.

Half of each plate should contain fruits and vegetables to ensure that all the nutritional value of your meal is to getting into your system.  Eating fruit raw will provide the best benefits since processing or canning can cause nutrients, vitamins and water to be lost.  A good way to get enough fruit is to keep whole fruit on the table or counter.  Pre-cut packages can be kept in the refrigerator with dip or low fat dressing, tossed on top of cereal, mixed in with waffles and pancakes, or stirred up with yogurt.  Make sure to clean fruit under running water and dry before preparing and eating, as well as keeping cleaned fruits away from raw meat, seafood and poultry.

Take an apple to work and keep sliced oranges in the refrigerator and you’ll be ready to get your proper amount of fruit per day!
