Milk and milk products provide calcium which is important for bone health. Choose low-fat or fat-free milk, cheese, and yogurt to reduce your intake of fat and calories. Switching from whole milk to 1% milk will save 50 calories and over 5 grams of fat per serving. Try using low or fat-free yogurts and milk in dips, salad dressings, and cream soups.

Eggs and cholesterol


Eggs are a good source of protein but the yolks are high in cholesterol; egg whites are cholesterol-free. A diet high in cholesterol may contribute to high blood cholesterol levels and increase your risk of heart disease. Experts recommend that you limit your cholesterol intake to less than 300 mg a day if you are a healthy individual and less than 200 mg a day if you have heart condition. Since one egg has about 213 mg of cholesterol, consider limiting other sources of cholesterol on days you eat eggs. The Mayoclinic offers tips to reduce cholesterol intake.

 

 

How strong are your bones?

HPRC Fitness Arena:
Strength-training for your bones.

We don’t give much thought to our skeletal systems until we do something that results in a broken bone. But bones play a vital role in a person’s general health and fitness. Our bones support us, allow us to move, and protect our vital organs from injury. They also store minerals—such as calcium and phosphorus—that are released into the bloodstream when our systems need them, for example, for muscle contractions.

Bone loss usually occurs gradually over a long period of time. By taking steps now to maintain healthy bones, you could ward off medical conditions such as osteoporosis.

One way to maintain optimal bone health is to eat foods rich in calcium and vitamin D. Without enough vitamin D, the body cannot absorb enough calcium from the foods we eat. This causes calcium to be taken our bones, which prevents the growth of new bone and results in weaker bones.

Good sources of calcium include low-fat dairy products, nuts and seeds, beans, broccoli and other leafy green vegetables, and fortified products such as orange juice that have added calcium. Good sources of vitamin D are egg yolks, fatty fish, beef liver, and milk with vitamin D. We also make vitamin D when our skin is exposed to the sun, although not everyone is able to get enough vitamin D this way.

Another way to keep your bones strong is to engage in physical activity. The best exercises are the strength-building and weight-bearing kinds such as walking, climbing, lifting weights, and dancing.

Other ways to maintain bone health include preventing falls by reducing the risk factors that you can control. Improve your balance and strength through exercise, maintain good vision, and make sure that your home is free of “falling dangers” such as poor lighting and loose rugs. Risk factors such as smoking, alcohol, medications, and body weight are also controllable. Smoking cigarettes, like vitamin D deficiency, can keep your body from using the calcium in your diet. Alcohol and certain medications (glucocorticoids, for example) also can cause your bones to become weak or lose mass. Moreover, being too thin increases one’s risk of developing weak bones that are more likely to break. If necessary, boost your diet with calcium and vitamin D supplements. Also consider talking to your physician about your bone health.

You may have heard again and again how important calcium and vitamin D are. Maybe you’ve even taken some or all of the steps above. But if you haven’t, start now and take action! Eat the right foods and exercise for strong bones.

Choose juice drinks wisely

With so many fruit juices on grocery shelves, do you find yourself asking, “Which one do I choose?"


With so many fruit juices on grocery shelves, do you find yourself asking “Which one do I choose?"  Look for fruit juices that are labeled “100 percent fruit juice” and read the ingredients.

Don't ignore your thirst

HPRC Fitness Arena:

Do you feel thirsty most or all of the time? According to HealthDay News, this could indicate a medical problem such as diabetes, infection, or kidney, liver, or heart failure. Other possible causes may include eating a spicy or salty meal, bleeding that causes significant blood loss, or certain medications. If you frequently experience excessive thirst and don’t know why, make an appointment with your health care provider.

Choose a better granola bar

Granola bars are great for a quick snack, but they're not all the same.

Granola bars are great for a quick, convenient snack.  Be sure to read the Nutrition Facts label to choose a bar that contains some protein and fiber, which will help you stay full longer. Some granola bars are high in sugar and fat, and also total calories. Next time you’re in a store, compare labels and look for one that has at least 4 grams of protein, 3 grams of fiber, and less than 200 calories.

Not all carbohydrate foods are equally effective

HPRC Fitness Arena:
Certain foods raise blood sugar better than others. It's important to what to eat after a moderate to high intensity mission or exercise.

As stated in the Warfighter Nutrition Guide (chapter 5) , certain foods raise blood sugar, or glucose, levels better than others. Ultimately, blood glucose from foods you eat are stored in the muscles and liver, in the form of glycogen, to supply energy for future physical activity.

The term glycemic index (GI) is used to describe how high a particular food will raise blood glucose. A high GI food is more effective for replenishing muscle and liver stores of glycogen than one with a low GI. Immediately after a moderate/high intensity mission or exercise, eat foods and beverages that have a moderate to high GI to replenish the glucose used up.
