A ketogenic diet (KD) is one that’s very high in fat, moderate in protein, and very low in carbohydrates. Traditionally, KDs have been used to help treat children with epilepsy (seizure disorder), but over the past few years they have gained popularity in the athletic community for purported performance-enhancing effects. At this time, the scientific evidence does not support the use of KDs to improve performance; in some cases, it can even decrease performance. It also can be difficult to maintain a ketogenic diet due to its extreme dietary constrictions, which come with potential negative side effects. Read more...
Those TV ads your children enjoy watching impact their food choices and their health. Kids see many commercials that advertise foods high in fat, sodium, and/or added sugars, especially during Saturday-morning children’s TV programming. The more kids are exposed to advertisements of unhealthy foods, the more likely they are to request—or sometimes beg—to eat them.
TV commercial viewing has also been linked to children’s weight problems. Kids who watch these commercials have an increased chance of eating foods containing too many calories and few nutrients. And the impact of TV commercials on kids’ food choices extends beyond what they eat at home. It’s also been linked to how often families eat at fast-food restaurants.
The American Academy of Pediatrics recommends children under 2 years old avoid all TV and screens, while children 3 and over watch no more then 2 hours of TV each day. Limiting the amount of time your kids watch TV means more time for them to be physically active. And less TV time means kids are exposed to fewer commercials that encourage unhealthy food choices.
Make sure to watch what your kids are watching—that means the shows and the commercials. When possible, watch TV together and move more during commercial breaks. Encourage them to get active by doing some jumping jacks, sit-ups, or push-ups!
Remember that commercials can influence kids’ food choices, so teach them to spot advertising tricks too. Keep the conversation going about the importance of healthy eating habits. Heading to the grocery store? Point out nutritious alternatives to your little ones, and ask older kids to help compare labels.
While there has been some discussion about whether adults should drink milk, most reliable scientific evidence shows that drinking milk offers many benefits. There are some important facts to consider when deciding whether to include milk in your meal plan.
- Milk contains calcium, vitamin D, and potassium. Most Americans don’t consume enough of these 3 essential nutrients, especially those who don’t drink milk. These all-important nutrients are necessary for bone growth, most of which takes place by the age of 18. However, they’re also needed to maintain bone as you age.
- It’s low-calorie! If your goal is weight maintenance or weight loss, fat-free (skim) and no-added-sugar flavored choices contain relatively few calories. And they’re rich in nutrients.
- Digestion problems? If you’re lactose intolerant, lactose-free milk and fortified soy milk are great alternatives.
- Chocolate milk makes an excellent post-workout beverage. It helps with refueling because it contains protein to rebuild muscles and carbohydrates to replenish energy stores.
The jury’s still out on whether milk-fat content matters, so follow the U.S. Department of Agriculture (USDA) recommendations on consuming low-fat and/or fat-free choices. And stay within the New Dietary Guidelines for Americans' recommendations for 3 daily servings of low-fat or fat-free dairy foods for anyone 9 and older. If you like milk, keep drinking it.
Your children and adolescents could benefit in many ways if your family eats at least 3 meals a week together. Dinnertime usually works best with family schedules, but other mealtimes work as well. Keep the following in mind when you sit down together at your next meal.
- Children and adolescents eat healthier. When kids eat with their families, they usually consume more fruits and vegetables. Kids also take in more fiber, calcium, and iron. And they drink fewer sodas and eat less saturated fats.
- Healthy habits have staying power. Adolescents who share in more family meals tend to eat healthier after they leave the nest, so this tradition can have lasting importance.
- Eating and talking together enables parents to tune into their kids’ needs. You might learn valuable information about your children’s friends, school, and interests—heading off any potential problems. They could also learn your thoughts on current events, healthy behaviors, and what matters to your family.
Sometimes parents feel that the task of putting meals together is too cumbersome. Meals can be quick and simple. They don’t have to be organic, costly, or even perfect. Simply being together around a shared table and eating a nutritious meal can do wonders for a family. Want a bit of encouragement? The majority of teens actually enjoy eating dinner at home with their families!
Knowing what to order in a restaurant or dining hall can be challenging when you’re trying to eat healthy on a budget. But there are ways to eat right and save money too.
- Check out the prices! Higher-priced entrées usually appear in the top right of a restaurant menu or menu board because that’s where your eyes tend to look first. You might want to think twice before placing your order.
- Look for deals. Higher-priced entrées are sometimes mixed with other offerings where you might overlook their prices. So make sure to check out what else is on the menu and compare prices. You might feel good about selecting something lower in price, even if it’s more than you’d usually spend. Choose wisely.
- Avoid the urge to splurge. Menus with red typeface and mouthwatering descriptions increase your appetite. Heading out for a fun night with friends? You could be tempted to spend more or order more food, which can leave you seeing red too. Sticking to your budget saves calories and dollars. Examine the menu carefully for tasty, healthy options.

Armed with this new intel, you can look forward to your next meal out without buyer’s remorse!
Breakfast really is the most important meal of the day. Eating cereal with milk, for example, nourishes your body with potassium, calcium, and vitamin D. Since 50% of all milk is consumed during breakfast, you might fall behind nutritionally if you skip your morning serving.
Studies show that breakfast eaters often weigh less and feel less hungry later in the day than those who skip breakfast. They often have improved concentration, problem-solving abilities, and hand-eye coordination too. If you’re an endurance athlete, fuel up at breakfast for peak performance.
Aim for a well-balanced meal by including any 3 of the following: grains, dairy, protein, fruits, vegetables, and healthy fats. Read more...
Are you including plenty of iron-rich foods in your eating plan? If you tire easily, have trouble concentrating, or experience shortness of breath, you might not be getting enough iron. It’s an essential nutrient that helps carry oxygen throughout your body, and it’s especially important if you engage in daily exercise.
Anyone’s at risk for iron deficiency, so be sure to eat a variety of iron-rich foods. Otherwise, your physical and mental performance could suffer.

Since the number one killer of men and women in the U.S. is heart disease, it’s important to know your cholesterol numbers. Cholesterol, an important substance made by your liver, forms cell structures, produces hormones, and helps with digestion. Here are the cholesterol numbers to know:
- Good, or high-density lipoprotein (HDL), cholesterol helps prevent fat and cholesterol from clogging your arteries. Know your HDL: Think H for healthy! A healthy number is greater than 60 mg/dL.
- Bad, or low-density lipoprotein (LDL), cholesterol can cause cholesterol buildup and block your arteries. Know your LDL: Think L for lousy! A healthy number is less than 100 mg/dL.
- Your total cholesterol score should be less than 200 mg/dL.
Starting at age 20, get your cholesterol checked every 5 years. Doctors use these numbers along with your age, blood pressure, and weight to help you manage your cardiac health. Smoking, diabetes, and heredity play important roles too.
There are ways to manage your cholesterol and heart health! Regular physical activity can lower LDL and raise HDL. A diet low in saturated fats can help as well, so make sure to check out the New Dietary Guidelines for Americans.

March is National Nutrition Month® and the Academy of Nutrition and Dietetics is encouraging everyone to enjoy different food traditions and celebrate the role that food brings to their lives. This year’s theme, “Savor the Flavor of Eating Right,” points out that the how, where, when, and why are just as important as what you eat. Making sure to enjoy the sights, sounds, memories, and interactions associated with eating are essential. Slowing down and taking time to appreciate the positive emotions that accompany mealtime are also important steps to developing a sustainable healthy-eating plan. Developing an eating pattern that includes nutritious and flavorful foods is the best way to savor the flavor of eating!
Every March, the Academy sponsors its month-long nutrition education campaign to share its message that improving overall well-being requires a lifelong commitment to healthful lifestyle behaviors, including nutritious eating practices and regular physical activity. Be sure to visit the Academy's website and check out its resources on food, health, fitness, and more.
