Nutrient density is a metric that compares the amount of nutrients you get to the number of calories you consume. A nutrient-dense food gives you a lot of bang for your buck when it comes to nutrition. For example, an entire cucumber, unpeeled, has just 45.2 calories, but you get almost 2 grams of protein, 1.5 grams of fiber and nearly 50 grams of calcium.
In contrast, 1 ounce of plain potato chips has 155 calories and 10 grams of fat. Potato chips do have some phosphorus, potassium and magnesium, but there are much better sources of these minerals available.
To meet your nutritional needs on the go, reach for these nutrient-dense foods:
If you're not sure what to pack, here are a few ideas:
If you're packing snacks for someone else, make sure you ask about their dietary restrictions before you buy prepackaged foods or cook a special meal. You may need to accommodate one or more of the following:
Large portion sizes may turn healthy snacks into unhealthy snacks. For example, 1 ounce of whole almonds has 164 calories and 14.1 grams of fat. Almonds are also packed with protein, fiber and minerals, so they're a good choice as long as you limit your intake. If you eat 3 ounces, your caloric intake increases to 492, which is nearly one-third of the 1,600 calories per day recommended for seniors who don't do some type of daily exercises.
If possible, avoid packing hot foods. These foods must be kept at 140 degrees Fahrenheit or higher to prevent foodborne illness. Unless you can take a slow cooker with you, it's tough to keep foods at this temperature while you're on the go. If you take cold foods, keep them in a cooler with a bag of ice or several ice packs.
Nobody likes soggy food. If you plan to use salad dressings, sauces or condiments, pack them in their own containers. Otherwise, the liquid will soak into bread, croutons and other dry items. For example, if you plan to pack sandwiches, keep the mustard, mayo and tomato slices in separate dishes.
Reusable containers cost a little more than plastic bags and other disposable items, but they're well worth the investment. If you use a glass or plastic container, you don't have to worry about messing with plastic wrap, aluminum foil or other products. These containers may also keep food fresher, as many of them have locking lids.
