You may be well aware that vegetables are a crucial part of a healthy diet, but not all vegetables are created equally. In fact, there are a range of vegetables, from starchy root vegetables to leafy greens and water-packed veggies like cucumbers and squash. All food provides energy through calories, yet some foods are well-known for their energy-boosting power. Fiber-rich vegetables are the most powerful when it comes to providing long-lasting energy and hydrating nutrients to the body.
Why You Crash
To understand what foods provide the best energy, it may be helpful for you to know which foods sap your energy and cause you to crash. Often, dieters seek energy-boosting foods because they notice a sudden fatigue, or "crash," after certain meals -- or while cutting calories. This crash occurs because of a drop in blood sugar. According to registered dietitian Cynthia Sass in "Shape" magazine, one culprit -- sugar -- hits the bloodstream quickly, causing a sudden rise in energy. This steep and sudden rise is followed by a fast crash, as the sugar is quickly burned as fuel and depleted. Because most sugary foods like cakes, candy and soft drinks do not contain vitamins and antioxidants, they offer no long-term energetic effects. Sass suggests cutting out junk foods and, instead, satiating the sweet tooth with fruit, a food that contains sugars but is also packed with fiber, vitamins and antioxidants.
Fiber and Vegetables: Long-lasting Energy
One reason vegetables provide long-lasting energy is their high fiber content. Because vegetables like green beans, broccoli, cauliflower and asparagus are full of healthy fiber, they fill the body and fuel it for a longer period of time than foods higher in calories and lower in fiber. New York City-based registered dietitian Caren Feingold said in "Shape" magazine that focusing on feeding your body as many nutrients as possible is the best way to energize your body. This maximizes the stored energy your body can use from the food you eat.
Dehydration and Energy
Dr. Martin Lipsky, a professor and chairman of the department of family medicine at Northwestern University Feinberg School of Medicine and Evanston Northwestern Healthcare, said in "Fitness" magazine that dehydration is one of the main culprits of low energy and fatigue. Dehydration causes decreased circulation of the blood, since the body is trying to conserve energy. When this happens, the muscles are cut off from oxygen, making them feel tired and lethargic. Drinking water, along with consuming nutritious, hydrating vegetables such as cucumbers, carrots, celery and peppers will help your body maintain its water balance and keep your muscles energized.
Tips for Adding More Fiber-rich Vegetables to your Diet
If you do not eat many fruits and vegetables, adding them into your diet by replacing sugary snacks with healthier options is easy with a little planning. Cutting fiber-packed veggies like celery, carrots and snap peas and placing them in plastic baggies can help you grab a healthier, more hydrating snack on the go. Similarly, water-rich fruits like apples and pears are easy to toss in a handbag or gym bag and provide a much healthier snack than chips, candy or sugar-filled bars. Replacing starches like white rice and potatoes at dinner with steamed green beans, broccoli and asparagus will raise your fiber count even further and help your metabolism continue to burn throughout the day and night.
