Do you know what a serving size is for different food groups? Here are a few helpful tips for standard serving sizes:
A one-cup serving of cereal or other grain is about the size of your fist; one medium fruit is about the size of a baseball; a half-cup serving of ice cream is about half a baseball; three ounces of meat, fish or poultry is the size of a deck of cards.

The FDA held a press conference on 12/15/2010 announcing that it was sending a letter to all dietary supplement trade associations, as well as posting a message to consumers, about the growing problem related to the sale of various misbranded drug products masquerading as "dietary supplements."
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.
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.
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.
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.
The Wall Street Journal is reporting on the problem of how to package healthy snacks for vending machines.
One of the biggest makers of vending machines, and fruit and vegetable marketer Fresh Del Monte Produce Inc. say they are tackling this problem with a new machine specifically designed to dispense whole bananas and fresh-cut fruits and vegetables.

Do you find the nutrient claims listed on many foods confusing? You are not alone!
Such claims are strictly defined by the Food and Drug Administration (FDA). Here are common cholesterol-related nutrient content claims with a detailed description of what each means. If a food claims to be cholesterol free, it means that one serving of the product contains less than two milligrams of cholesterol and two grams or less of saturated fat. Low cholesterol means that one serving contains 20 or fewer milligrams of cholesterol and two grams or less of saturated fat. Finally, reduced cholesterol means at least 25 percent less cholesterol than the regular product and 2 grams or less of saturated fat. Arm yourself with this information and be an educated consumer next time you shop.
It’s important to eat something after a strenuous workout to replenish muscle stores of carbohydrate and have plenty of protein available to repair the body. Try a peanut butter and jelly (PBJ) sandwich for a great post workout meal! It’s cheap and packed with nutrition if you use natural peanut butter without added sugar and fats, and whole-grain bread.

KENS Channel 5 in San Antonio, TX has posted an article on their website that reports that, according to the military, the number of prospective recruits are just too fat to enlist, which is making it difficult to fill their ranks.
The article cites a non-profit group called Mission Readiness, made up of retired senior military leaders, who feel there is a solution to the problem.
The group has a three-point approach that would solve the obesity problem for prospective recruits:
- Get the junk food and high-calorie beverages out of our schools.
- Increase funding for the school lunch program.
- Support the development, testing and deployment of proven public-health interventions.
