Is there more to hydration than water?
Water is a great choice for staying hydrated, but it isn't your only option. Beverages such as milk, juice and herbal tea can also help you meet your daily fluid needs. Foods also contribute to your daily fluid needs. Many fruits and vegetables, such as watermelon and spinach, are 90 percent or more water by weight.
Working out? Remember to drink up
If you do any activity that makes you sweat, you need to drink extra water to cover the fluid loss. It's important to drink water before, during and after a workout. Hot or humid weather can make you sweat and requires additional fluid.
Eat more of these key nutrients
The typical American diet is low in fiber, vitamin D, calcium, iron and potassium. For this reason, they're listed on the Nutrition Facts label to encourage Americans to choose foods rich in these important nutrients.
Don't go cuckoo for coconut water
Coconut water is the clear fluid inside coconuts. Because it has natural electrolytes, such as potassium, sodium and manganese, it's popular for rehydration after exercise. But coconut water isn't calorie-free, which means plain water is still the smart choice for a post-workout drink.
What's considered moderate alcohol use?
Moderate alcohol use for healthy adults typically means up to one drink a day for women and up to two drinks a day for men. One drink is 12 ounces (355 milliliters) of beer, 5 ounces (148 milliliters) of wine or 1.5 ounces (44 milliliters) of distilled spirits (80 proof).
What's the difference between juicing and blending?
Juicing extracts liquid from fresh fruits and vegetables. This liquid contains most of the vitamins, minerals and phytonutrients but very little of the fiber found in whole fruits and vegetables. Blending, on the other hand, purees the edible parts of fruits and vegetables. Thus, less fiber is lost.
Juicing is no substitute for whole foods
Juicing fresh fruits and vegetables produces a liquid that contains most of the vitamins, minerals and phytonutrients found in the whole fruit or vegetable. However, healthy fiber is lost during most juicing. So be sure your diet also includes a variety of whole fruits and vegetables.
