September is National Whole Grains Month! Whole grains are natural sources of vitamins, minerals, fiber, and other nutrients that are essential for good health. The Dietary Guidelines for Americans, 2010 recommends that at least half of your grain choices should be whole grains.
Try these tips to add more whole grains to your meals and snacks:
- Start with a hearty breakfast that features whole-grain cereals such as steel-cut oats, bran flakes, or shredded wheat. Eat breakfast on the run? Try switching to whole-wheat toast or whole-grain bagels instead of plain bagels. Substitute low-fat bran muffins for pastries.
- Lunchtime sandwiches using whole-grain breads or rolls are full of flavor and fiber. Swap out white-flour tortillas with whole-grain corn tortillas.
- Dinner sides can really shine when you replace white rice with exotic black or red rice or wheat bulgur. Add wild rice or barley to soups, stews, and casseroles. Whole-grain pastas give a nutty flavor to many dishes.
- Snacks can feature whole grains too: popcorn, graham crackers, or granola bars are tasty, healthy options.
- And don’t forget dessert: brown rice pudding, oatmeal cookies, or whole-wheat baked goods are just the ticket—wholesome and satisfying.
Remember, eating a variety of whole grains not only ensures that you get more health-promoting nutrients but also helps make your meals and snacks more interesting. The U.S. Department of Agriculture has more information about the health benefits of whole grains and even more tips on how to include them in your diet.
For some people, eating certain foods can cause serious allergic reactions, even death! The most common food allergens are milk, eggs, fish and shellfish, tree nuts (such as almonds, walnuts, and pecans), peanuts, wheat, and soy. Other food allergies are possible, so it’s important to read food labels for ingredient information if you are at risk. Click here for more information.
Sodium—a component of table salt—is an essential element. It helps your muscles and nerves function correctly and maintains the proper balance of your body’s fluids. However, too much sodium in your diet may increase your risk of high blood pressure, heart attack, stroke, and certain types of cancer.
The average American consumes about 3,400 milligrams (mg) of sodium every day, mostly in the form of salt. But the current Dietary Guidelines for Americans recommends that adults limit their sodium intake to just 2,300 milligrams per day—roughly the amount in one teaspoon of table salt.
The guidelines also recommend that certain “at-risk” groups limit their sodium intake to about 1,500 mg per day: adults over the age of 51, African Americans, and people who have high blood pressure, diabetes, or kidney disease.
Recently, the Institute of Medicine (IOM) looked at the evidence supporting the current recommendations regarding sodium intake. IOM concluded:
- Research supports current recommendations to reduce sodium intake to about 2,300 mg daily.
- More research is needed to support the recommendation that those “at risk” should cut back to 1,500 mg or less a day.
Bottom line? If you’re in an at-risk group, speak to your doctor or registered dietitian about whether you should reduce your salt intake. For just about everyone else: Cut back on the salt.
How? Most of the sodium Americans consume comes from processed foods—tomato sauce, soups, canned foods, bread, and prepared mixes—but it can also come from foods naturally high in sodium—cheese and some types of seafood. Also, many restaurant foods are high in sodium, but sometimes you can request low sodium items. The best way to ensure a low sodium diet is to eat whole foods such as fresh or frozen fruits and vegetables; lean, unprocessed poultry and fish; unsalted nuts; whole grains; and low-fat dairy products such as skim milk or yogurt.

June is National Fresh Fruits and Vegetables Month. And it’s no wonder—during the warm summer months many fresh fruits and vegetables are at their peak. So take advantage of nature’s bounty and make an effort to include more fruits and vegetables into your family’s diet. Here are some tips to help:
- Start early: Top your morning breakfast cereal with fresh berries, bananas, or peaches for added flavor and nutrition.
- Add some crisp lettuce leaves and juicy tomato slices to a sandwich or wrap.
- Kids love foods they can “dip,” so encourage them to dip their veggies in a delicious, healthy fresh tomato salsa.
- Keep fresh veggies and fruits on a platter in the refrigerator so kids (and you!) can grab some any time—cooling off by the pool, reading a book, or cooking dinner.
- Go to a farmers’ market to find the freshest, in-season produce.
- Plant your own garden—or just a small tomato plant on the back porch. There’s nothing quite like homegrown fruits and vegetables.
- Have some dessert! Fruits are full of natural sweetness—the perfect way to round out a meal.
Eating fruits and vegetables may reduce your risk of cancer, diabetes, and many other diseases. To find out how many fruits and vegetables you and your family should be eating, use this great calculator from the Centers for Disease Control and Prevention. The U.S. Department of Agriculture has more information about the benefits of eating fruits and vegetables as well as lots of great tips to help you incorporate fruits and vegetables into your diet.
Some recent evidence suggests that probiotic foods can contribute toward a healthy population of microorganisms in your digestive tract (gut). But what exactly are probiotic foods?
According to the World Health Organization (WHO), probiotic foods contain “live microorganisms which, when consumed in adequate amounts as part of food, confer a health benefit on the host.” In other words, they are foods that contain microorganisms (primarily bacteria and yeast) that may play a role in keeping the human gut healthy.
An astonishing number and variety of microorganisms—some good and some bad—occupy every nook, cranny, and passageway of our bodies. Most inhabit our digestive tract and play key roles in digesting food and digestive health. Maintaining the proper balance of good and bad organisms is essential. In fact, having more “bad” than “good” microorganisms is also associated with increased risk for short-lasting diseases such as colds and gastroenteritis and long-lasting diseases such as asthma and certain types of cancer.
More than 5,000 different strains of bacteria may reside in the average person’s digestive tract, which makes it hard to determine which ones might be good and which ones might be bad. But generally speaking, two strains seem to offer the greatest benefit to humans—Lactobacillus and Bifidobacterium. Both can be found in many widely available probiotic foods.
Fortunately, it’s easy to find probiotic foods these days. Take a walk down the dairy aisle of your local grocery store and you’ll likely find yourself inundated with products promising a variety of beneficial health effects, many of which are attributed to the products’ probiotic content. Choices include traditional fermented foods such as yogurt, kefir, and buttermilk as well as foods far from the dairy aisle such as sauerkraut, pickles, and miso (a soybean product).
Keep in mind that if you eat a greasy cheeseburger, fries, and a sugary soda followed by a yogurt “chaser,” it’s unlikely you’ll see much benefit from the probiotic organisms in the yogurt. The greatest benefits from eating probiotic foods occur when they are part of a diet that includes whole grains, plenty of fruits and vegetables, and low-fat sources of dairy and protein. For more detailed information, read “Oral Probiotics: An Introduction” from the National Center for Complementary and Alternative Medicine.
According to the 2010 Dietary Guidelines for Americans, solid fats and added sugars (SoFAS) contribute nearly one-third of the average person’s daily calories!
Solid fats, as the name implies, are solid at room temperature; they include both saturated and trans fats. They tend to raise “bad” (LDL) cholesterol, increasing your risk for heart disease. Sources of solid fats include butter, cheese, meats, and foods made with these products, such as cookies, pizza, burgers, and fried foods. For more information, read how to tell the difference between solid fats and oils.
Added sugars can contribute to weight gain and tooth decay. Although some foods such as fruit and milk contain naturally occurring sugars, added sugars are usually found in processed foods such as sodas, sports or energy drinks, candy, and most dessert items. It can be hard to identify added sugars on food labels, but you can learn how to recognize hidden sources of sugar.
Foods containing SoFAS are often high in calories but don’t provide many important nutrients such as vitamins, minerals, or fiber. Fortunately, it’s easy to cut back on SoFAS by eating a diet rich in whole foods such fruits and vegetables, whole grains, low-fat dairy products, and lean sources of protein, and following the MyPlate guidelines.
Synthetic drugs are laboratory-made substances marketed and sold as alternatives to illegal drugs such as marijuana, cocaine, and amphetamines. Although most are advertised as “all-natural,” they may have serious health effects and violate the Uniform Code of Military Justice (UCMJ). HPRC takes a look at two examples of synthetic drugs, their legal status, and how they can affect service members in “HPRC’s Answer: Synthetic Drugs of Abuse.”
The annual Army “Strong B.A.N.D.S.” campaign is set to launch for another year beginning in May. Strong B.A.N.D.S. promotes physical fitness, nutrition, optimal health, and resilience by focusing on Balance, Activity, Nutrition, Determination, and Strength—forming the acronym B.A.N.D.S. The campaign has activities at numerous garrisons to help educate soldiers, their families, and civilians. Strong B.A.N.D.S. is a campaign of the U.S. Army Installation Management Command Family and Morale, Welfare and Recreation directorate and is “designed to energize and inspire community members to live a healthy lifestyle.”
Check out the website for detailed information and to see if there is a Strong B.A.N.D.S. activity near you.
Carnitine is a naturally occurring substance in the human body that helps cells use fat for energy. The liver and kidneys can produce carnitine from amino acids provided by the diet, but carnitine also comes from many foods, especially red meat, and is an ingredient in many dietary supplements and energy drinks.
Sometimes doctors use carnitine to treat certain heart conditions. Recent clinical trials suggest that carnitine supplements may help reduce many of the complications associated with heart attacks, such as chest pain and irregular heart rhythms.
But new research suggests that long-term consumption of dietary carnitine also may play a role in the development of atherosclerosis—“hardening of the arteries”—especially in people who eat red meat regularly. So what’s the bottom line? More research is needed to determine the risks and benefits associated with carnitine.

Energy drinks have been in the news lately, mostly due to media reporting on a group (doctors, researchers, scientists, and politicians) writing to the Food and Drug Administration (FDA) to express concern over the use of these drinks by adolescents. Much of the concern has to do with the amounts of caffeine in these drinks, among other issues. Energy drinks also may contain large amounts of other stimulants, including guarana, yohimbe, yerba mate, kola nut, methylsynephrine, Citrus aurantium (Bitter Orange), and Ma Huang (ephedra). Although listing the total amount of caffeine on the label would help, consumers should be aware that there are often other stimulants in energy drinks.
The American Academy of Pediatrics has written several articles over the last year about the potential risks associated with the adolescent population using energy drinks. One very recent article outlines the harmful effects of energy drinks on adolescents, including increased heart rate, high blood pressure, anxiety, digestive problems, sleep disturbances, and dehydration. The withdrawal effects after habitually consuming energy drinks is also an issue, as it can lead to headaches and attention problems. Also, the ingestion of energy drinks by adolescents who take prescription drugs for Attention Deficit Hyperactivity Disorder (ADHD) or who have eating disorders or diabetes is another topic of concern.
The amount of caffeine contained in energy drinks is not regulated, as the FDA does not regulate caffeine in foods or beverages, except that the maximum concentration for caffeine in cola beverages is 71 mg per 12 oz. The amount of caffeine in energy drinks ranges from 50 to more than 500 mg per can or bottle. The American Academy of Pediatrics recommends that children and teens drink no more than 100 mg of caffeine per day. To put that in perspective, an eight-ounce cup of coffee typically contains about 100 mg of caffeine (or more), and the most popular caffeine-containing sodas contain around 30 to 55 mg in a 12 oz. can. Not knowing how much caffeine and other stimulants are contained in energy drinks is a potential health threat.
Furthermore, the caffeine and other stimulants contained in the energy drinks, when combined with alcohol, can mask the symptoms of alcohol intoxication, potentially leading to risky behavior. The American Academy of Pediatrics advises parents and doctors to talk to children about the dangers of mixing alcohol and energy drinks, and the Centers for Disease Control and Prevention has a fact sheet on the potential risks.
Parents, educators, and healthcare professionals need to focus on educating adolescents about potential problems associated with consuming these high-stimulant products. Companies are heavily marketing their products by featuring athletic superstars, which causes children and adolescents to confuse energy drinks with sports drinks. Generally speaking, adolescents don’t need energy drinks, and they should be made aware of the potential dangers. It’s definitely a case of “buyer beware.”
