Roughly one in 3 children in the U.S. is overweight or obese, but you can do something about it. Obese children are more likely to be obese as adults and at risk for diabetes and other health conditions, so it’s important to act early. September is Childhood Obesity Month, so there’s no better time to start.
Let’s Go! is a childhood obesity prevention program to help kids eat better, be more physically active, and live healthier lives. Just remember their “5-2-1-0” countdown message:
5 – Get your kids to eat at least 5 fruits and vegetables every day. Make it fun with kid-friendly recipes. Let your kids choose fruits and veggies at the store that they want to try, help prepare meals and snacks in the kitchen, or even plant a vegetable garden together.
2 – Cut down kids’ screen time to 2 hours or less a day. (No screen time for those under 2.) Get them to try other ways to be entertained, such as playing a game or going on a scavenger hunt. These types of activities will get your kids’ bodies and minds working.
1 – Kids need at least one hour of moderate to vigorous physical activity every day. Sound like a lot? Just think of it as playing instead of exercise! Make it a family affair. Go to the playground, play a sport, or simply go for a walk around the neighborhood together.
0 – Zero sugar-sweetened sodas, sports drinks, and fruit drinks. Instead, have your kids drink water and fat-free or one-percent milk. If your kids aren’t fans of plain water, add a little pizazz with some sliced berries, citrus fruits, melons, or kiwis. And they can eat the fruit when they’re finished drinking!

It’s cause for concern: Approximately 30% of teens consume energy drinks on a regular basis. Energy drinks provide no nutritional benefit and can actually pose health risks to adolescents, including increased heart rate, high blood pressure, anxiety, digestive problems, sleep disturbances, dehydration, and even death. Teens who consume energy drinks are also more likely to engage in unhealthy behaviors such as drinking more sugar-sweetened beverages, smoking cigarettes, and using drugs and alcohol.
Many of the negative effects associated with energy drinks are due to the large amounts of stimulants in these beverages. Their caffeine content can range from 50 to more than 500 mg per can or bottle. The American Academy of Pediatrics recommends that children and teens:
- consume no more than 100 mg of caffeine per day (equal to about 2 cans of caffeine-containing soda or one 8 oz. cup of coffee) and
- avoid energy drinks altogether.
However, the amount of caffeine teens consume from energy drinks is trending upwards, in part due to heavy marketing with celebrity athletes. Be sure to talk to your teens about the potential problems associated with energy drinks, and make sure they don’t confuse them with sports drinks.
You can take control of how your daily eating habits help or hurt your body’s joints. The physical demands of training and missions—along with day-to-day exercise, overuse, injury, and aging—can take their toll on your joints over time. There are certain eating habits you can practice to help keep your joints happy and healthy for the long run.
- Aim for a healthy weight. Extra weight means extra stress on your joints – walking alone can cause your knees to take on 3–6 times your body weight. Maintain a healthy weight or lose weight if you need to. Visit HPRC’s Fighting Weight Strategies for ideas.
- Fight inflammation. Include omega-3 fatty acids on your plate to reduce your body’s inflammation. Salmon isn’t your only source; foods such as English walnuts, flaxseeds and their oil, canola oil, and other fish contribute omega-3s to your eating plan. See HPRC’s omega-3 table for more foods rich in omega-3s.
- Fill up on fruits and veggies. Fruits and vegetables, all of which are nutrient-heavy, have been linked to a lower incidence of joint diseases such as osteoarthritis and rheumatoid arthritis. Fill half your plate with fruits and vegetables at meals, and build snacks around them too.
- Revive with vitamin C. Because of its role in forming collagen (the main component of connective tissue) and as an antioxidant, foods high in vitamin C are important for joint health. Oranges, Brussels sprouts, strawberries, red peppers, and kiwi are excellent sources.
Focusing on a healthy weight and filling up on nutrient-rich foods, along with regular exercise and stretching, can help optimize the long-term health and performance of your joints.
The Food and Drug Administration (FDA) is again warning about the dangers of powdered pure caffeine. At least 2 deaths (both teenagers) were associated with it in 2014, yet it continues to be sold, primarily in bulk online. FDA recently sent warning letters to 5 distributors of pure powdered caffeine, warning about potential serious health effects. FDA notes that it’s difficult to determine the difference between a safe amount and a toxic amount but that one teaspoon is roughly equivalent to 28 cups of coffee. For more information, read FDA’s update and HPRC’s 2014 article.
Make at least half of your grain choices whole grains. Unlike refined grains, whole grains contain all parts of the grain and are good sources of fiber and other nutrients that are essential for good health. Try these tips so you can enjoy more whole grains in every meal and snack:
- Breakfast: Start with a hearty breakfast that features whole-grain cereals such as steel-cut oats or shredded wheat. Have to eat breakfast on the run? Try switching to whole-wheat toast or whole-grain bagels instead of plain bagels.
- Lunch: 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, brown, or red rice, quinoa, or bulgur. Add wild rice or whole-grain barley to soups, stews, and casseroles. In the mood for noodles? Try whole-wheat pastas for added texture.
- Snacks: Snacks can feature whole grains too. Air-popped popcorn, whole-grain crackers, and granola bars are tasty and healthy options to keep you going throughout the day.
Can’t tell if some of your grain products are whole? Look at the ingredients list and make sure the first ingredient says “whole wheat” or “whole grain.” HPRC also has a grains table that points out nutritious grains (with and without gluten). And keep in mind that words such as “100% wheat” and “multigrain” don’t necessarily mean whole grain. For more information, visit the Whole Grains Council.
Many factors affect your sleep, including stress and exercise, but your diet can also have a huge impact on the quality of your sleep, particularly in the hours before you go to bed. By improving your evening food habits you can sleep better, which can have a positive impact on your mental and physical performance, immune function, relationships, and overall health and well-being. Try these tips to be on your way to a better night’s sleep:
- Limit caffeine. Caffeine can disturb your sleep even many hours later. If you typically drink coffee or tea in the afternoon or after dinner, opt for a decaffeinated version. And be wary of hidden sources of caffeine.
- Avoid alcohol. Some people think of alcoholic beverages as a nightcap to help you sleep better. While it may help you go to sleep faster, it also reduces sleep quality by waking you up in the middle of the night.
- Eat balanced meals. Eating balanced meals daily will help you get all the nutrients you need, such as B vitamins and magnesium, to promote better sleep. A balanced plate is ½ a plate of fruits and vegetables, ¼ plate of whole grains or starchy vegetables (corn, peas, potatoes), and ¼ protein, plus a serving of healthy fat (oil, avocado). In addition, your body takes long to digest fats, so eating too much fat may keep you from falling asleep.

The post-workout recovery phase is just as important as the workout itself. Refueling with the right nutrients can help your body heal damaged muscles, build more muscle, and replace nutrients lost during exercise to prepare you for your next workout or mission. A combination of protein and carbs in a snack is the key for recovery. It’s also important to drink enough fluids for rehydration. The best time to refuel is within 45 minutes after your workout, but if you plan to have a meal within 2 hours, you can skip the snack. Otherwise, you might be eating too many calories, which would spoil all your hard work. For more guidelines and snack ideas, please visit HPRC’s Peak Performance: Refueling.
You missed a meal and plan to exercise soon or your next meal is hours away, but your stomach is rumbling – what can you do? One way to fill your nutritional gaps is with nutrient-packed snacks.
Nutrient-packed snacks should consist of both “plants” and protein. Plants—such as fruit, vegetables, and whole grains—contribute carbohydrates, vitamins, and minerals. Protein—including low-fat dairy, lean meats, nuts, and seeds—contribute to muscle building and repair. Here are some simple snack ideas to have on hand during your workday, at the gym, and during missions to keep you at the top of your game, both mentally and physically:
- Apple or pear with 2 tbsp of natural peanut butter or almond butter
- Homemade trail mix –2 tbsp of dried fruit (any kind) mixed with a handful of nuts or seeds (any kind)
- Whole-grain crackers with 1 oz of cheese
- Whole-grain English muffin with 2 slices of turkey
- Slice peaches or plums, add to 1 cup of cottage cheese or plain Greek yogurt, sprinkled with cinnamon
- Cut-up veggies like carrots, cucumbers, bell peppers, and sugar snap peas; dip in hummus or bean dip
Low glucose (blood sugar) from lack of food can affect memory, learning, and attention. In addition, inadequate fuel can slow down your physical performance and your ability to recover from injuries, strenuous exercise, or difficult missions. Snacking can be a great way to fuel your body between meals and provide extra nutrition if you’re highly active.
But don’t forget to look at your portion sizes! Remember, this is a snack, not a meal. Snacking when you’re not truly hungry or large portion sizes can result in weight gain. Learn more about stocking your snack drawer.
Carbohydrates are essential fuel for muscles and provide a source of quick energy. But is it true that eating extra carbs before an athletic event or mission will improve your performance? Carbs becomes especially important when you put your body to test during athletic competitions and events. If your body’s available carbs run out, fatigue sets in and you can “hit the wall.” To avoid this, many athletes load up on extra carbs such as bread, pasta, and rice. Read more about the concept behind carb loading and how it can affect your performance.
Getting the right nutrients at the right time can give you the edge you need when it comes to performance. Are you drinking the right kind of beverage to keep you hydrated? Do you know what to eat after a workout to optimize your recovery? Find answers to these questions and more in HPRC’s FAQS: Fueling for Performance.
